OFF-ROAD ALL-WHEEL DRIVE MOTORCYCLE Russian patent published in 2023 - IPC B62M7/02 B62M17/00 

FIELD: mechanical engineering.

SUBSTANCE: e invention relates to the field of mechanical engineering, in particular to all-wheel drive off-road motorcycles. The motorcycle contains a main, seat frame with a seat, front and rear wheel drive and a steering fork. The main frame is rigidly connected to the seat frame. The seat frame is connected by a spring-loaded shock absorber to the rear wheel swingarm. The swing axis of the rear wheel is fixed in the main frame and together with the shock absorber forms the rear suspension of the motorcycle. The pivot point of the rear wheel is at the center of mass of the motorcycle, dividing its mass into two equal parts. The front wheel, rigidly fixed in the steering fork, is connected to the main frame of the steering column by a bearing assembly. The motorcycle engine output shaft is connected to the rear wheel drive sprocket by a single chain drive. The output shaft of the engine is connected with the front wheel by the first chain drive connected to the bearing assembly with the constant angular velocity bearing, and the second chain drive connected to the said bearing assembly and the front wheel drive sprocket.

EFFECT: design simplification.
