この発明は、砂地や軟弱路面の走行に適する前後輪駆動
自動二輪型に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a front and rear wheel drive motorcycle suitable for running on sandy or soft road surfaces.

になっている。(Prior art) In general, motorcycles have an engine connected to a multi-gear transmission via a manual clutch, and traditionally connected to the rear wheel with a chain, so that the engine drives the rear wheel and the front wheel drives the engine. It is designed to be steered. Then, depending on the running speed, the multi-gear transmission is selectively switched between two gears as appropriate to drive the vehicle.
又、差動クラッチなどを介して、伝動軸の出力を分岐し
、前輪も駆動するようにしたものがある。In addition, there are some models in which the output of the transmission shaft is branched via a differential clutch or the like to drive the front wheels as well.

スムースな走行ができない不便がある。(Problems to be Solved by the Invention) A motorcycle whose engine drives only the rear wheels becomes unable to run if the rear wheels slip, and cannot run smoothly on soft roads (such as sand). Further, in a vehicle that drives front and rear wheels, it is necessary to provide a differential clutch or a differential device in order to absorb the difference in rotation between the front wheels and the rear wheels. Moreover, the differential OJ device 6 requires a non-slip device that can transmit driving force to the other wheel when one wheel slips, making the device large and expensive to manufacture. . In addition, on sandy or soft roads, the road surface resistance is large, so with multi-gear 11 transmissions, the vehicle speed will drop significantly while changing the gears.
This has the inconvenience of not being able to run smoothly.

する。In view of the above, this invention connects two continuously variable belt transmissions to one end of the crankshaft of the engine, drives the front wheels and the rear wheels with the two continuously variable belt transmissions, and rotates the front and rear wheels. The front and rear wheel drive automatic that absorbs the difference with a continuously variable belt transmission and can run smoothly with continuously variable speed, and can be manufactured lightweight and inexpensively by compactly attaching two continuously variable belt transmissions to one end of the crankshaft. The purpose is to obtain a two-wheeled vehicle.

The front and rear wheels are each driven by a stepped belt transmission, with the fixed pulley of the drive side pulley connected to the crankshaft in the center, and two movable pulleys of the continuously variable belt transmission on both sides of the fixed pulley. The reason is that they are shared.

されてスムースに走行できる。(Function) In the two continuously variable belt transmissions, as the rotation of the crankshaft increases, the movable pulleys of the two driving pulleys move toward the fixed pulley as the centrifugal way 1 expands, so that the belt is not wound. Increase the diameter and automatically increase speed steplessly. The fixed pulley has belt rests on both sides and is also used as the drive pulley for the two continuously variable belt transmissions, so the length of the fixed pulley to be attached to the crankshaft can be shortened, and the length of the crankshaft can be shortened. The length can be shortened and the impact can be made 21 times lighter. Two continuously variable belt transmissions each drive the front and rear wheels, absorbing the difference in rotation between the front and rear wheels, and continuously shifting automatically, allowing smooth running on sandy or soft roads. Even if one of the wheels slips, the wheels on the other side are driven and the vehicle can run smoothly.

等速ボールジヨイント２４が設ＧＪである。The driving pulley 5.6 is a pair of a movable pulley 7.8 and a fixed pulley 9, and the movable pulley 7.8 includes:
A centrifugal weight 10.11 is installed inside, and the rotation of the centrifugal weight 10.11 spreads outward along the slope, and the movable pulley 7.8 is moved toward the fixed pulley 9 and brought closer to the belt. The diameter of the winding should be increased. The fixed pulley 9 has tapered belt contact surfaces on both sides and also serves as the fixed pulley 9 of the two continuously variable belt transmissions 3.4. Therefore, only one fixed pulley 9 is required, and the crankshaft 2 can be made short and compact. The driven pulley 11 of one continuously variable belt transmission 3 is
Centrifugal clutch 1 located behind the crankshaft 2 for starting
2 and a gear reducer 13, and further connected to a rear wheel 15 via a chino 14. The driven pulley 16 of the other continuously variable belt transmission 4 is disposed above and in front of the crankshaft 2, and is connected to the face width 20 via a centrifugal clutch 17 for starting, a gear reduction gear 1118, and a chino 19. The front fork 21 to which the front wheel 20 is attached can be steered by turning it left and right with a handle 22, and a constant velocity ball joint 24 is installed in the middle of the chino 19 at 23.
