ALL WHEEL DRIVE MOTORCYCLE Russian patent published in 2014 - IPC B62M17/00 B62M7/00 

FIELD: transport.

SUBSTANCE: invention relates to all wheel drive motorcycle. All wheel drive motorcycle includes frame with telescopic front wheel yoke, fuel tank, internal combustion engine and front and rear wheel drive installed on the frame. The drive is made in the form of clutch for coupling with output shaft connected to infinitely variable transmission on the output shaft of which universal joint is installed which is connected with driving shaft of rear wheel via spline joint with bevel gear and pinion of rear wheel drive. On the same output shaft, driving sprocket of front wheel drive chain is rigidly fixed. The driven sprocket is fixed on front drive driving shaft mounted in two bearings fixed to frame and located under fuel tank. On the other end of driving shaft, driving bevel gear is rigidly fixed which rotates large intermediate bevel gear positioned at an angle of 90° to driving shaft axis. Large gear axis coincides with yoke mounting assembly axis and is fitted in bushing of yoke rotation on its independent bearings, where driven bevel gear taking torque from intermediate bevel gear is fitted on butt end of divided driving shaft having spline joint and installed in bearings the bodies of which are mounted on inner side of yoke. On the lower end of driving shaft, the second small bevel gear is fitted which transfer rotation at an angle of 90° to large bevel gear which is fixed to side surface of front wheel hub which wheel is installed on axle.

EFFECT: improvement of motorcycle performance characteristics.
