Abstract
A snowmobile assembly including a chassis and suspension system. The suspension system configured to allow a selected suspension travel. The snowmobile further including a cooling system assembly.
Claims20
A snowmobile assembly, comprising:
- a chassis assembly having a tunnel assembly;
- a skid plate assembly having a skid plate surface;
- a track having a contact surface configured to propel the chassis and a skid surface configured to contact the skid plate assembly;
- an engine housed at least partially within the chassis assembly configured to drive the track;
- a suspension assembly configured to connect the chassis and the skid plate assembly in a moveable manner, the suspension assembly including:
- a first torque arm extending from a first end to a second end, and
- a second torque arm extending from a third end to a fourth end;
- wherein the first end is fixed to the chassis assembly at a first fixation point such that the first torque arm is operable to rotate about the first fixation point;
- wherein the third end is fixed to the chassis assembly at a second fixation point such that the second torque arm is operable to rotate about the second fixation point and the third end is configured to be coupled to an upper guide roller assembly;
- and
- wherein the skid plate surface is operable to travel at least about 20 centimeters from a full extension to a full collapse position relative to the second fixation point.
