In a vehicle that drives wheels, it is necessary to provide a differential clamp or a differential device in order to absorb the difference in rotation between the front wheels and the rear wheels due to steering. Moreover, the differential gear needs to be equipped with a non-slip device that can transmit and drive the drive horn to the middle wheel on the other side even if the middle wheel on the J side slips, which increases the size of the device and increases the manufacturing cost. arrive. Furthermore, on sandy or soft roads, the resistance of the road surface is large, so the multi-stage mountain transmission has the inconvenience of slowing down while changing gears, making it impossible to run smoothly.

二輪車を得ることを目的とする。In view of this, the present invention connects two continuously variable belt transmissions to one end of the crankshaft of the engine, so that the two continuously variable belt transmissions can be compactly accommodated on one side of the engine case. A stepless belt transmission drives the Mi wheels and the rear wheels separately, and the difference in rotation between the front and rear wheels can be absorbed by the stepless belt transmission, which eliminates the need to install a differential clutch, making it possible to produce at low cost, and improving speed change operation. To provide a surface wheel drive motorcycle which can run smoothly without the need for bamboo and can run without any trouble even if one side slips.

な場所でも乗り越えることができる。(Function) Since the drive pulleys of the two continuously variable belt transmissions are mounted side by side on one end of the engine crankshaft, the two continuously variable belt transmissions can be housed compactly on one side of the engine case. The difference in rotation between the front wheels and the rear wheels due to front wheel steering is
Since it can be absorbed by a continuously variable belt transmission, there is no need for a differential clutch, etc., and it can be manufactured in a small size and at low cost. On the other hand, a continuously variable belt transmission automatically shifts gears and does not require shifting, so it can run smoothly on sandy or soft roads. Even if one wheel slips, the driving force is transmitted to the other middle wheel, allowing the vehicle to overcome any slippage.
