SKI SUSPENSION FOR SNOWMOBILES

摘要

In a snowmobile ski suspension each ski is carried on a trailing swing arm pivotally mounted in the front of the snowmobile. The swing arm carries a steering tube in which the ski leg is pivotable about a generally upright axis. A hydraulic damper-coil spring assembly is attached between a mounting on the lower end of the swing arm, and a bracket within the front part of the snowmobile, and controls upwards and downwards deflection of the ski assembly. The skis on opposite sides of the vehicle are interconnected by a transverse torsion bar stabilizer which is arranged to transmit deflection forces from the ski on one side to the ski on the opposite side and vice versa, and thus enhance the roll stability of the machine.
