Abstract
A snowmobile includes a frame and a tractive assembly pivotably coupled to the frame. The tractive assembly includes a first rail, a second rail, a first crossmember extending between the first rail and the second rail, an arm having a first end pivotably coupled to the frame and an opposing second end, and a stop assembly. The stop assembly includes a second crossmember coupled to the arm, a cam coupled to the second crossmember, a first bracket coupled to first ends of the first crossmember and the second crossmember, a second bracket coupled to opposing second ends of the first crossmember and the second crossmember, and one or more stops coupled to at least one of the first bracket or the second bracket, the one or more stops configured to engage a portion of the cam to selectively prevent rotation of the arm.

A snowmobile comprising:
- a frame;
- and
- a tractive assembly pivotably coupled to the frame, the tractive assembly including:
- a first rail;
- a second rail;
- a first crossmember extending between the first rail and the second rail;
- an arm having a first end and an opposing second end, the first end pivotably coupled to the frame;
- and
- a stop assembly including:
- a second crossmember coupled to the arm;
- a cam coupled to the second crossmember;
- a first bracket coupled to first ends of the first crossmember and the second crossmember;
- a second bracket coupled to opposing second ends of the first crossmember and the second crossmember;
- and
- one or more stops coupled to at least one of the first bracket or the second bracket, the one or more stops configured to engage a portion of the cam to selectively prevent rotation of the arm.
A snowmobile comprising:
- a frame;
- and
- a tractive assembly pivotably coupled to the frame, the tractive assembly including:
- a first rail;
- a second rail;
- a first crossmember extending between the first rail and the second rail;
- a first arm having a first end and an opposing second end, the first end pivotably coupled to the frame;
- a second arm having a first end and an opposing second end, the first end of the second arm pivotably coupled to the frame;
- a stop assembly including:
- a second crossmember coupled to the first arm and the second arm;
- a cam coupled to the second crossmember;
- a first bracket coupled to first ends of the first crossmember and the second crossmember;
- a second bracket coupled to opposing second ends of the first crossmember and the second crossmember;
- and
- one or more stops coupled to at least one of the first bracket or the second bracket, the one or more stops configured to engage a portion of the cam to selectively prevent rotation of the first arm and the second arm;
- and
- a block stop configured to engage at least one of the first bracket or the second bracket to selectively prevent rotation of the first bracket and the second bracket, the block stop extending between the first rail and the second rail.
A snowmobile comprising:
- a frame;
- and
- a tractive assembly pivotably coupled to the frame, the tractive assembly including:
- a first rail;
- a second rail;
- a first crossmember extending between the first rail and the second rail;
- an arm having a first end and an opposing second end, the first end pivotably coupled to the frame, a first angle defined between the arm and the first rail;
- a stop assembly including:
- a second crossmember coupled to the arm;
- a cam coupled to the second crossmember;
- a first bracket coupled to first ends of the first crossmember and the second crossmember, a second angle defined between the arm and the first bracket;
- a second bracket coupled to opposing second ends of the first crossmember and the second crossmember;
- and
- one or more stops coupled to at least one of the first bracket or the second bracket, the one or more stops configured to engage a portion of the cam to selectively prevent rotation of the arm, the second angle limited by the one or more stops;
- and
- a block stop configured to engage at least one of the first bracket or the second bracket to selectively prevent rotation of the first bracket and the second bracket, the block stop extending between the first rail and the second rail, the first angle limited by the block stop;
- wherein a first distance from the first crossmember to a rearmost portion of the snowmobile is greater than a second distance from the block stop to the rearmost portion of the snowmobile, and a third distance from a surface engaged by the tractive assembly to the first crossmember is less than a fourth distance from the surface engaged by the tractive assembly to the block stop.
