Suspension device for vehicles

摘要

A suspension device for motor driven vehicles such as snowmobiles comprises a pair of slide rails which are resiliently suspended under the vehicle body to ensure engagement of the ground-engaging portion of a flexible endless track with the ground, the endless track being driven by a drive sprocket wheel journalled on the front portion of the vehicle body and stretched at its rear portion over rear idler wheels journalled on the rear portions of the slide rails. The resiliency of the suspension device is adjusted to prevent skidding of the rear portion of the endless track.
