(57) Abstract:

Usage: of the invention in mototransportnye tools. The use of this power plant with an output shaft opposite the hinge axis of the suspended wheel and shaft with universal joints at both ends, connecting the output shaft and the wheel hub to the drive wheels. 4 Il.

The invention relates to mechanical engineering and can be used in the construction of motorcycles, scooters, mopeds.

Known mototransportnye transmission in which torque from the output shaft of the propulsion system to the drive wheel is transmitted via a chain drive or shaft with an angular gear (construction and maintenance of motorcycles. Century, Chinaeu, 1982 M. Chamberlain, S. 8).

A disadvantage of the known devices is the low reliability and a large mass unsprung parts.

The objective of the invention is to improve the reliability and reduce the unsprung mass parts mototransportnye transmission.

This goal is achieved by the fact that the hub is pivotally suspended wheels are directly connected to the output shaft of the power unit through a shaft with universal joints at both ends.

With the Yong General view of the device; in Fig. 2 the V-belt transmission with the option of Fig. 3 transmission directly driven by the output shaft of the box; Fig. 4 transmission with angle gear.

Mototransportnye transmission is suspended from the hinge arm 1, which is located on the hub 2 drive wheel 3. On the reverse side, opposite the axis of the wheel 3 is an output shaft of the power unit 4, which is connected to the hub 2 by the shaft 5 with the drive shafts 6 and 7.

Mototransportnye transmission can be used in conjunction with V-belt option. For example, in Fig.1, where the torque from the engine 1 through the driving pulley 2, the belt 3 and the driven pulley 4 is supplied to the propeller 5. Between the driven pulley 4 and the propeller shaft 5 is mounted in the gear transmission to the desired gear ratio.

Mototransportnye transmission can be used directly driven by the output shaft gear box changes gears (Fig. 3), if, for example, a scooter and power plant, which includes the engine, clutch and gearbox changes gear in one unit 1, and is located in the rear part of the scooter.

Mototransportnye transmission can be used with the power plant, consisting and is, 4). In this case, the torque from the engine from the gearbox changes gears 1 through the shaft 2 and the angular gear transmission 3 is transmitted to the propeller shaft 4. Angular gear transmission mounted on the frame of motorcycles and scooters motionless.

When driving motorcycles and scooters torque from the output shaft of the power unit 4 through the shaft 7, the shaft 5 and the shaft 6 is transmitted to the leading wheel 3. This transfer allows the wheel 3 when the motion to oscillate the lever 1.

This eliminates the contradictions inherent in the prototype. You can create motorcycles and scooters of high reliability, any composition with high performance.

Mototransportnye transmission containing a power unit with a device for transmitting torque to the drive wheel, pivotally suspended drive wheel, wherein the hub is pivotally suspended wheels are directly connected to the output shaft of the power unit through a shaft with universal joints at both ends, whereby the output shaft of the power plant is perpendicular to the plane of rotation of the wheel.
