BIKE + CAR = MOTOMOBILE | MODEL CONSTRUCTION

They parted ways at the dawn of the automobile, and since then, the development lines are not intersecting until now… we are Talking about a motorcycle and car.

The first has always attracted consumers and their qualities of speed, maneuverability, and simplicity, and, importantly, relatively low retail price. The only quality always been fair criticism: motorcycle, unfortunately, does not provide even basic comfort. Among them, and the inconvenience of landing — top, in position, resulting in long trips to the numb muscles. Yes, and “jump” in the saddle of a motorcycle not too comfortable — this equally applies to the driver and the passenger.

A considerable disadvantage of a motorcycle is its complete vulnerability to weather conditions, which makes this vehicle almost summer. Not only that: even in good warm weather, the rider has to equip yourself accordingly to protect yourself from the wind and dust. Well, among other things, the vulnerability of the driver and passengers not contribute to of risk of injury at.

The solution suggests, I think, is obvious: to provide a motorcycle with a lateral trailer the closed fairing, a motorcycle saddle-bag to replace two adjacent automobile seats. Here’s a motorcycle, I think, would be free from the above disadvantages of the tools of daily use.

I offer a “Home” — one of the variants of this bike with an unusual location of the engine: on the side leading the rear wheels, it has.

The layout engine is located above the gas tank will clear up space between the front and rear wheels for chairs for driver and passenger. The passenger seat is easily removable; this allows you to have a large enough cargo area to transport various weights, including long items up to 2.1 m. this area is Suitable for equipment bed for one person.

The fairing of the machine, called my motomobile asymmetrical shape (is also consistent with the asymmetric layout of the chassis), two-door. All these features of the layout and laid in motomobile — a vehicle chassis which corresponds to the layout of the motorcycle with a sidecar, and the level of comfort for driver and passenger — regular passenger vehicle.

Fig. 1. The layout of the motomobile “Veksha“:

1 — the driver’s seat, 2 — front wheel with fork (scooter Tulitsa), 3 — the rear (driving) wheel, 4 — passenger chair, 5 — engine type T-200 (scooter Tulitsa), 6 — pinion and gear wheel transmission, 7 — “broken” the steering shaft with hinges gook, 8 — fuel tank 9 — side wheel, 10—tubular frame.

Fig. 2. The power unit motomobile “Vecchio”:

1 — engine type T-200, 2 — gear transmission, a 3 — frame of motomobile, 4 — wheel hub (of the scooter), 5 — axle rear wheel, 6 — axle swing arm suspension, 7 — gear transmission, 8 — shaft drive gear, 9 — flexible coupling coupling, 10 — trailing arm suspension 11 rear shock absorber (motorcycle), 12 — bracket, 13 — pivot hinge swing arm, 14 — pole hinge.

Fig. 3. Motomobile “Vecchio” at various stages of its manufacture:

1 — the machine — frame with wheels, engine and fuel tank; 2 — frame machine with mounted on it a frame and Polikom; 3 — car frame covered with fiberglass and duralumin sheets; 4 — fully assembled motomobile.

The drawings and photographs reflect the sequence of manufacturing “Vecchio”. Frame — flat welded from steel tubes Ø 32 mm with a wall thickness of 2 mm. the Engine is hung on the frame by means of brackets similar to brackets scooter Tulitsa (which, in fact, borrowed motor T-200M working volume of 200 cm³ and a power of 14 BHP).

Torque from the output shaft of the gearbox is transmitted to the rear wheel by a chain, as most light and medium motorcycles (and scooters), and through flexible coupling on a pair of cylindrical gears and a smaller set on the axis of the longitudinal swing of the suspension arm, and one double — axle rear wheels. It is a big trial run a lower gear in accordance with oscillations of the lever of the suspension on rough roads. Elastic suspension member of the rear wheel is motorcycle rear shock absorber, hinged in welded to the frame bracket.

Suspension side of the wheel is made also for longitudinally oscillating the lever — similar to the rear wheel.

For the front of the bridge used a regular fork scooter Tulitsa complete with shock absorbers, wheel and steering column.

The wheel “Vecchio” — type motorcycle, with arms specially selected forms. With the turning fork it is connected with the intermediate shaft on two Hooke joints. This scheme allows to choose the optimal tilt steering colony in accordance with the landing of the driver.

Fairing motomobile — mixed design: it has aluminum frame of curved templates angular profiles combined with the shell — part is also dural, from a sheet thickness of 1 mm, the part is fiberglass.

So first on the frame of the motomobile dural mounted the bottom and then going from an angular profile frame fairing; the joints of the profiles in this case are enhanced by kerchiefs of duralumin sheet. In the middle of the machine is fixed an arc of security — it is also dural, from the profile type “t”; its shape corresponds to the cross section of the body.

As already mentioned, the casing frame is combined. First, the frame is sheathed mm sheet aluminum, and then glued a layer of fiberglass cloth on the epoxy binder. The roof and the bottom of the motomobile — only GRP; the same material is laminated and the front wheel fairing and the headlight housing. After curing of the resin housing vyshkurivaetsya and, if necessary, podsalivaya with the subsequent polishing of the surface. The hood over the front wheel wikiepedia separately, according to the gypsum dummy.

Door motomobile also collected from dural profiles with a covering of sheet duralumin with the subsequent covering it with fiberglass epoxy resin. Inside the cabin glued sheet foam and then faux leather.

Electrical, instrumentation and controls motomobile correspond to the regular equipment scooter Tulitsa. Its maximum speed when driving with a passenger reaches 80 km/h fuel Consumption per 100 kilometers at a speed of 70 km/h is 3.9 l. Dry weight is only 193 kg — that is almost the same as that of a motorcycle with a sidecar type IZH. Close to the motor and the dimensions of the “Vecchio” — 2110X1420X1325 mm.

As the test showed, “Vaxjo” perfectly “holds” the road, easy to drive, stable in turns.
