Crafts made from rubber tires. Crafts from tires for the garden (42 photos): making a flower bed, practical crafts and an ottoman

I don’t think anyone will argue with the fact that a velomobile is good for health. Well, for lovers of technical creativity it is doubly useful, as it allows you to gain invaluable experience before creating more serious designs. Velomobile, about which we'll talk, was designed and manufactured in the station workshop young technicians(SUT) of our city, together with the club members. I must say that the idea of ​​​​creating it came to me much earlier, and therefore I prepared the materials and most of the spare parts (in particular, the wheels) myself, at my own expense. True, the wheels and materials were mostly picked up from abandoned bicycles, so the costs were not so great.

Velomobile - two-seater, four-wheeled. The front wheels are steering, the rear wheels are driving. The carriage has two pedal drives - each for its own wheel.

The frame of the velomobile is welded, two-spar. However, both side members and the front cross member are made as one piece - bent from a pipe with an outer diameter of 40 mm - from the handrail of a decommissioned city bus. The ends of the side members are bent upward and, together with the traverses welded to them, serve as supports for the seat backs.

A rear cross member is welded between the seat back supports - it serves as the upper support for the suspension units (springs and hydraulic shock absorber) rear axle.

The front support of the seats themselves is a low portal, supported by its uprights on both side members and also connecting them. A handbrake handle is mounted in its middle, and gear shift levers are mounted at the ends of the crossbar.

Rear axle is pretty unusual design. Its basis is a closed subframe welded from the arches of the backrests metal beds. On its sides, the axle shafts of the drive wheels with a three-speed block of drive sprockets are fixed in bearings.

Double, four wheel, two-wheel drive velomobile with soft suspension on all wheels

A parking brake disc is mounted (welded) on the left axle shaft. The service brakes are pliers and act on the front wheels. The subframe is connected to the frame (or rather to the portal) by means of a swinging axis and two oblique levers made from equal-flange angle No. 2.5.

The front wheel suspension is independent on springs. The springs are placed in the bushings of the steering knuckle axles. The suspension travel is small, and it only absorbs minor road irregularities. Therefore, to soften the impact from larger irregularities, soft rubber bumpers (thick washers) are also installed on the axle on both sides of the bushings.

The rear wheel suspension is “semi-independent”. The subframe is suspended on springs (from the Karpaty moped) with a hydraulic shock absorber from the Verkhovyna moped. The wheels of the car are different. The front ones are from a Kama bicycle, the rear ones are from a Ural bicycle. But both of them were altered: their hub bushings were replaced with longer ones (twice).

It should be noted that assembling a wheel is not an easy task, and to facilitate this operation a jig was made. A circle with a diameter equal to the wheel rim was cut out of a sheet of plywood, and four stop stands were fixed around its circumference, with a height equal to the part of the hub protruding beyond the rim. Then the new (elongated) hub was secured with a bolt with a spacer in the center of the plywood circle and the wheel was equipped with spokes - first the spoke was inserted into the hole in the hub flange, and then its end into the hole in the rim and tightened with light tension. After installing all the spokes, the wheel was removed from the jig and the spokes were finally tensioned, checking for the absence of a figure eight in the wheel.

The front wheels are swivel. The steering is homemade. It consists of a steering wheel, a tubular shaft and a rack-and-pinion steering mechanism with a transverse tie rod. The rack and the rod end are connected using a ball joint. The other end of the rod is connected to the steering knuckle lever of the right wheel, and from it to the left wheel there is another one - an inter-wheel steering rod. Claw-type working (running) brakes are also mounted on the front wheels.

The velomobile has a pedal drive. The driver and passenger each have their own, three-speed, independent. Three gear speeds are enough to move over any rough terrain. But it must be admitted that with an empty velomobile weighing 55 kg, it is difficult for one person to pedal even at the lowest speed when moving uphill.

The pedal units are cut assemblies from old road bike frames and welded at a convenient distance from the seats to the side members. The three-speed sprocket blocks of the rear axle shafts are homemade, and only the sprockets themselves are used from a touring bike. Homemade and drive chain tensioner-switch.

The crew seats are homemade. Their base, attached at four points to the frame elements, is made of a 1.5 mm thick duralumin sheet. The base is covered with a lining - a foam mat, which is covered with a cover made of bright nylon fabric.

On a long journey I usually took a plastic cape with which I covered other necessary things placed in the trunk. The trunk was a mesh stretched between the side members and the front axle beam in the bow of the carriage (not shown in the drawing, but clearly visible in the photograph).

I would also like to note that for connection various elements frames and suspensions into a single design used household welding machine, and most of the small rotation parts (axles, bushings, etc.) are turned on a small school lathe.

I admit that, in addition to trips on official business, I used the velomobile for two seasons (in the warm season) for trips to work and back home. In addition, on weekends I used it for outings into nature with my wife or brother.

After two years of operation, the D-4 engine was installed on the velomobile, and specifically on its rear left wheel, and its other “life” began as a “motormobile”. It is this version of the velomobile, converted into a motorcycle crew, that is shown in the photo.

This velomobile dad made it for his beloved Zlatushka. You have already often met our daughter in my other publications, where we do various crafts. Nowadays there are a lot of battery-powered cars in stores that need to be charged frequently, and they are of no use, while the velomobile develops perfectly.

This is a worthy analogue to the usual bike, which will allow you to teach your baby to ride. The velomobile is, as the name suggests, a hybrid bike and car. It's four wheeled vehicle, which is equipped with a comfortable seat and steering wheel, similar to a regular car.

Such a vehicle cannot develop high speed; there is no need to be afraid that the child will fall out.

The design itself a velomobile is like that that it is difficult to turn it over. It stands stable on all four wheels, so you don't have to worry. Now dad happily walks with little daughter and catches admiring glances and shares his experience on how to make one yourself velomobile

Publications on the topic:

Our children love to make crafts with their own hands. Creativity attracts them with the opportunity to show their abilities and do something interesting.

As part of Book Week kindergarten An exhibition of homemade books was held. Since I am not only a teacher, but also a mother of two children who...

I propose to make a gift for our mothers from scrap material. Goals: To make flowers with your own hands for family and friends. Tasks:1.

Dear colleagues! Women's Day is just around the corner! I would like to present to your attention a master class on making a flower for your gift.

With the onset of summer, I really want to decorate my area. Various items are used, to which we give a chance for a second existence. So out.

March 8th is coming soon, what to give on this wonderful day? After all, the teacher deserves great reward for your work! So I decided to do it myself.

Do you know what a velomobile is? You can not only teach your children how to ride a bicycle, but it is also quite possible for adults to use it as a means of transportation. Did you know that you can assemble a velomobile with your own hands if you have drawings for a model with four wheels and the desire to do it? No? Then this article is just for you.

A velomobile is not just a toy for a child

A little history

The history of the creation of four-wheeled models began shortly after the invention of the first bicycle. Already in the 19th century there were drawings in which inventors tried to make carriages with a drive, like a bicycle, from pedals. Even cars had their own special variations on bicycle technology.

During times Soviet Union everything unnecessary was removed for mass production. Nowadays, basically this type of transport is nothing more than a children's tricycle. But there are still true connoisseurs of velomobiles, and today we’ll talk about how to make one at home.

Four-wheeled velomobile

Application of a velomobile

A bicycle structure that has four wheels is called a velomobile. It would seem that its use is more than limited, but in fact such an instance can be found in many areas.

Making a velomobile at home

Nowadays, everything can be bought, and a four-wheel velomobile is no exception. But its cost is more than high, and it does not always reflect your needs or desires. Therefore, you can try to make such an interesting and not so familiar vehicle yourself.

A bicycle is good, but with a roof and even a motor, it’s absolutely cool! Lightweight, comfortable, economical and covered with a tent on top for protection from rain and wind... a lot of positive things can be said about the development from JMK-Innovation - PodRide.

Many similar homemade products, as shown in the photo, are made all over the world, and there are even small-scale projects.

At the presentation of the Tesla Model, it was called a “mass electric car.”

Technical characteristics of the electric bicycle:

• Size: height - 145 cm, width - 75 cm.
• Weight: 70 kg.
• Power: (250 W, 0.33 HP).

Of course, PodRide looks like an amusement park car, but it’s more fun. After all, she is really capable of driving on the roads, and not best quality!

... and also pull a semi-trailer, also on bicycle wheels! Swedish designer and engineer Mikael Kjellman decided to make his contribution and added a new model to the technological cabinet of curiosities. His creation, PodRide, accommodates one passenger plus a trolley with luggage.

Four for stability, a lighter frame, a chain drive, pedals, a steering wheel, a seat, a folding rain canopy - that’s what a velomobile is! But the most important thing is the electric motor, with a power of 250 W or 0.33 hp. and a battery for it.

There is no room in the cabin for a large backpack. There is only a small compartment behind the driver's back.

The weight of PodRide turned out to be even less than that of its inventor - about 70 kg.

The driver sits on a soft seat with a backrest. All information about the trip is displayed on a pair of displays, one of which is the smartphone screen. PodRide even has a heated windshield and windshield wipers (though manually operated), and a fan to prevent fogging of the polymer windows.

On aluminum frame with air suspension, four wheels with a diameter of 20″ are fixed. The front ones turn, and the rear ones are driven by an electric motor through a 14-speed chain transmission (two sprockets in front and seven in the rear). The engine operates in “assistant” mode, helping the driver pedal and overcome inclines. On a non-incline section of the track, PodRide can accelerate to 25 km/h and travel up to 60 km on a single charge.

Due to the trapezoidal shape of the tension body, it rubs a little at the shoulders, but effectively leans forward when landing and on bumps.

It is also easier to ride on snow and sand because of the four wheels, and lighting equipment can be installed more powerfully than on a bicycle. Even in the salon there is LED lights so that it’s not so scary to go. Everything is very cool! See for yourself:

A good bike can go faster and further, but in winter or in inclement weather, riding a PodRide is clearly more comfortable. You don’t get wet in the rain, you remain protected from the wind and from traffic police :) The author of the invention registered his development as an electric bicycle and rides anywhere without insurance and the risk of losing his driver’s license.

In addition to simplicity - the main advantage of a bicycle, this walking stroller has advantages over its “ancestor”, the main ones being good stability in motion and when stopping and a comfortable driver’s position, like in a car.

The prototype was a velomobile published in some magazine. But its rather complex space frame, two-stage drive and steering made us think about how to simplify these components and make the car lighter. I believe that the problem was solved and we even received a copyright certificate for the production of an industrial design.

I offer readers a description and drawings of an improved velomobile.

This “reduction” of the prototype velomobile led, in fact, to the creation new car- only the layout remained from the previous one: two front steering wheels and one driving rear one. Therefore, before moving on to the description of the bicycle stroller components, it is worth noting those of them that were affected by the most radical changes.

Firstly, the frame was lightened to 4.5 kg - instead of being spatial it became planar. Secondly, a two-stage drive with an intermediate shaft (reduction gear) was simplified to a single-stage with an extended chain, which increased the coefficient useful action transfers. Third, the multi-speed drive wheel hub was replaced with a single-speed one, eliminating the need for a hand brake. Fourth, the steering wheel was moved from under the seat to its usual place - on the column in front of the driver, which eliminated the extra step in the steering. Finally, fifthly, The “chaise lounge” seat was replaced by a simpler but rigid one with a backrest tilted back, which provided better support when pressing the pedals with the feet, which is especially important when going uphill.

As a result of such alterations, the overall machine weight decreased to 20 kg(for the prototype it was 26 kg), providing almost the same consumer qualities as the prototype with a multi-speed drive.

Step-by-step construction of a velomobile

A steering column 330 mm long from a pipe with a diameter of 28 mm is welded to the traverse at the front. Its stability is ensured by two figured scarves.

The wheelbase (the distance between the wheel axles) of the bicycle stroller, compared to the prototype, is slightly reduced (the turning radius has also decreased), and the track (the distance between the front wheels) has been increased.

The chassis, wheel suspension and steering are quite simple. The rear drive wheel, like a bicycle wheel, is attached to the ends of the fork side members. The suspension of the front steering wheels, although it differs from a regular bicycle suspension and is more similar to a car's pin suspension, is also simple - the camber and toe angles of the wheels are not adjustable.

The pins are loosely inserted into bronze plain bearings (fluoroplastic can also be used) of the bushings at the ends of the traverse, tightened from above with castle nuts and cottered through holes drilled in the threaded ends of the pins. The pivots have cube-shaped heads with through side holes with a diameter of 12 mm. The axles (trunnions) of the front steering wheels are secured in these holes.

A groove and two diagonal blind M4 threaded holes are made at the bottom edge of the head of each kingpin. The ends of the rotary arms are secured in the grooves with two M4 screws each. Their other ends are pivotally connected to flattened tie rod ends made of steel rod with a diameter of 7 mm. In the middle of the rod, an eye is welded for hinge connection of the free end of the steering bipod. The other end of the bipod is welded to the lower end of the steering shaft, made of a thin-walled steel pipe with a diameter of 21 mm, in the upper part of which a longitudinal slot is made.

The shaft in bronze (or fluoroplastic) sliding bearings is placed in the steering column, the steering column is inserted into it on top, and all the parts in the slot are tightened with a clamp. Two more clamps on the same shaft at the top and bottom of the steering column prevent its longitudinal displacement.

The drive (transmission) is no different from the drive of a regular road bike, only the chain is slightly longer. Its tension is regulated by moving the rear wheel hub axis in the grooves of the fork tips. When the chain is stretched, it is enough to remove one or two links from it to make dragging adjustment possible again.

The seat of a bicycle stroller is ordinary - like a chair, only its back is tilted at a significant angle for a more comfortable position for the driver. The base of the seat is an arc made of a thin-walled steel pipe with a diameter of 16 mm with four crossbars made of a steel U-shaped profile with dimensions of 55x10 mm. The seat and back cushions are attached to the tyurechins. The pillows are simple: foam rubber is glued to a plywood base and covered with leatherette on top.

The location of the seat on the frame was chosen taking into account the optimal distribution of the load from the driver’s weight on the wheels. It was also taken into account that the driver’s seating height should provide him with necessary review when moving in traffic. Therefore, the seat is installed on two rack-brackets made of the same profile as the crossbars, only the size of the shelves is 15 mm. The brackets are attached to the frame side members with a pair of brackets using four M5 bolts each. This mount allows, if necessary, to move the seat (back or forward) to adjust the distance to the pedals according to the driver’s height.

Simplification of the design of the bicycle stroller, in comparison with the prototype, did not entail the final elimination of the previous elements that created (albeit insignificant) comfortable riding conditions. If desired, without changing the frame and steering, you can install a multi-speed drive, a fairing with a windshield and roof, and a seat headrest, thus turning the stroller back into a velomobile.
