関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a straddle-type four-wheel vehicle used for traveling on rough terrain, etc., and more specifically, to a wheel suspension system for a straddle-type four-wheel vehicle in which rear wheels are supported by separate suspensions. Regarding.

It is also required from the viewpoint of safety that the driver obtains stable maneuverability. A suspension installed in a vehicle in order to obtain such stable maneuverability is particularly important in this type of vehicle. By the way, in conventional tricycles developed for this type of purpose, a drive axle with a rear wheel attached thereto is supported by a swing arm, and a rear suspension is disposed between the swing arm and the frame. However, with such tricycles, when either of the left or right wheels receives an impact from an uneven road surface while driving, the vehicle body may tilt or the like.
The impact applied to the wheels was directly applied to the car body, resulting in poor driving stability. On the other hand, this is not a desirable structure for four-wheeled vehicles as well, as it has poor followability to the road surface.
本発明は、上記事情に鑑みてなされたもので、
路面からのシヨツクを吸収し、走行時における車

懸架装置を提供することを目的とする。 The present invention was made in view of the above circumstances, and
It is an object of the present invention to provide a wheel suspension system for a straddle-type four-wheeled vehicle that can absorb shock from the road surface and improve the stability of the vehicle body during driving.

動軸を二点で支持するようにしたことにある。 A feature of the present invention is that each rear wheel is provided with a separate drive shaft, each of these drive shafts is supported by an individual swing arm and suspension, and the output of the engine is transmitted to each sprocket provided on the drive shaft. In the wheel suspension system for a straddle-type four-wheeled vehicle, one end of the swing arm is rotatably supported on the main frame, and the other end is bifurcated to sandwich the sprocket and drive the drive shaft. This is supported by two points.

The output is transmitted to the output shaft 13, and the left and right sprockets 14 1 and 14 2 rotate simultaneously. The rotational power of these sprockets 14 1 and 14 2 is transmitted to the sprockets 15 1 and 15 1 through chains 16 1 and 16 2 .
15 2 will be transmitted separately. Next, as the sprockets 15 1 and 15 2 rotate, the drive shafts 4 1 and 4 2
rotate, and the rear wheels 3 supported by the drive shafts 4 1 and 4 2 rotate at the same time. And when running,
When an impact is applied to one rear wheel 3 due to unevenness of the road surface, only the rear wheel 3 to which the impact is applied vibrates, and the vibration is absorbed by the suspension 6 1 or 6 2 . In this way, the impact applied to one rear wheel 3 is not transmitted to the other rear wheel 3, so that the vehicle body can maintain a stable posture.
