摘要： Various embodiments of a snowmobile are disclosed. The lower arm is arranged below the upper arm. The lower arm includes proximal portions and connected to the ski support frame. The lower arm extends outwardly from the proximal portions and in the vehicle width direction and connects the ski support frame and the ski. The proximal portions and of the lower arm are positioned higher than the lower end of the engine. At least a portion of the lower arm is positioned higher than the rotational center of the crank shaft. This structure can prevent the center of gravity of the vehicle body from becoming high and reduce running resistance when the vehicle traveling in deep snow.

摘要： The present specification relates to a snowmobile. The upper arm includes two proximal portions connected to the vehicle frame and the upper arm extends outwardly from the two proximal portions in the vehicle width direction and the upper arm is connected to the knuckle. The two proximal portions are rotatable so that the knuckle and the skis can move up and down relative to the vehicle frame. The axis Ax2, passing through the rotation center C2 of the two proximal portions of the upper arm, goes through a position of the rotation center of the secondary shaft or through a position above the rotation center of the secondary shaft. This structure can reduce the force acting on the vehicle body frame via the upper arm and prevent an increase in the force.

摘要： This specification relates to a snowmobile. Each of the right suspension and the left suspension includes a damper capable of expanding and contracting according to the vertical movement of the lower arm and a spring that exerts spring force in the expansion/contraction direction of the damper. The cylinder of the right damper and the cylinder of the left damper are connected to each other through a hydraulic fluid channel so that the hydraulic fluid flows between the cylinder of the right damper and the cylinder of the left damper. This snowmobile can reduce the difference in contact pressure on snow surface between the left ski and the right ski, when the vehicle turns.
