A ventilating wheel provides a plurality of angled vanes extending from a hub. The ventilating wheel secures to the slide rail of a snowmobile suspension system. An endless track extends over the underside of the slide rail. A Hyfax may secure to the slide rail interposed between the track and slide rail to reduce friction therebetween. The ventilating wheel is in rolling contact with the track and is rotated thereby to draw air and snow over the slide rail. In some embodiments, air and snow flow over the radiator is induced. The ventilating wheel may serve as an idler wheel defining the shape of the track. In other embodiments, the ventilating wheel mounts to a straight portion of the slide rail and serves to reduce pressure on the Hyfax. In still other embodiments, the ventilating wheel serves only to increase air and snow circulation.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A cooling system for a snowmobile suspension system comprising: an endless track encircling a space; a linear bearing for supporting the endless track; and a ventilating wheel coupled to the linear bearing and having a portion thereof in rolling engagement with the endless track, the ventilating wheel having a plurality of vanes, each vane having an aerodynamically contoured surface oriented at to an angle with respect to a rotational plane of the ventilating wheel, the angle being greater than parallel and less than perpendicular with respect to the rotational plane, the plurality of vanes operating to move air through at least a portion of the space encircled by the endless track. 2. The cooling system of claim 1, further comprising a low-friction material interposed between the linear bearing and the endless track and arranged to receive air from the space encircled by the endless track. 3. The cooling system of claim 1, wherein the ventilating wheel further comprises: a hub rotatably mounted to the linear bearing; and a rim circumscribing the plurality of vanes and secured to the distal ends thereof, the rim in rolling engagement with the endless track. 4. The cooling system of claim 3, wherein the endless track engages a substantial angular portion of the rim. 5. The cooling system of claim 3, wherein the track tangentially contacts the ventilating wheel. 6. The cooling system of claim 1, comprising multiple ventilating wheels each secured to the linear bearing. 7. The cooling system of claim 1, wherein the linear bearing includes two slide rails arranged substantially adjacent and substantially parallel to one another. 8. A cooling system for a snowmobile comprising: an endless track; a linear bearing for supporting the endless track; and a ventilating wheel coupled to the linear bearing comprising a hub rotatably mounted to the linear bearing, a plurality of vanes extending radially from the hub, at least one of the vanes having an aerodynamically contoured surface that is acutely angled relative to the plane of rotation of the ventilating wheel to draw air past the at least one of the vanes and over a desired region of the linear bearing, the acutely angled aerodynamically contoured surface having an angle being greater than parallel and less than perpendicular with respect to the plane of rotation, and a rim in rolling engagement with the endless track, the rim circumscribing the vanes and secured to the distal ends thereof, the vanes being the sole means securing the rim to the hub. 9. The cooling system of claim 8, wherein the vanes comprise substantially planar members angled relative to the plane of rotation of the ventilating wheel, to draw air between the vanes during wheel rotation. 10. The cooling system of claim 8, wherein the endless track engages a substantial angular portion of the rim. 11. The cooling system of claim 8, wherein the track tangentially contacts the rim. 12. The cooling system of claim 8, further comprising a low-friction material interposed between the linear bearing and the endless track, the plurality of vanes of the ventilating wheel drawing air and snow toward an interface located between the endless track and the low-friction material. 13. The cooling system of claim 8, wherein the linear bearing comprises two parallel slide rails. 14. The cooling system of claim 13, wherein multiple ventilating wheels engage each slide rail. 15. A cooling system for a snowmobile comprising: an endless track slidably secured to the snowmobile; a ventilating wheel mounted to the snowmobile, the ventilating wheel comprising a hub rotatably mounted to the snowmobile, a plurality of vanes extending generally radially from the hub, each vane having an aerodynamically contoured surface oriented at to an angle with respect to a rotational plane of the ventilating wheel, the angle being greater than parallel and less than perpendicular with respect to the rotational plane to permit air flow over the aerodynamically contoured surface such that the air is moved past the aerodynamically contoured surface and over a desired region of the snowmobile as the wheel spins, and a rim circumscribing the vanes and secured to the distal ends thereof, the rim in rolling engagement with the endless track. 16. The cooling system of claim 15, wherein the vanes are the sole means securing the rim to the hub. 17. The cooling system of claim 16, wherein the snowmobile comprises a linear bearing mounted thereto in sliding contact with the endless track, the ventilating wheel being mounted to the linear bearing having the rim in rolling engagement with an inner surface of the endless track. 18. A method for cooling a snowmobile comprising: providing a ventilating wheel having angled, flow-inducing vanes, said wheel being secured to a linear bearing of a snowmobile suspension, the vanes angled relative to a plane of rotation of the ventilating wheel such that an aerodynamically contoured surface of each vane is oriented with respect to the plane of rotation such that a substantial portion of the aerodynamically contoured surface has an angle greater than parallel and less than perpendicular with respect to the plane of rotation; and rotating the ventilating wheel to move air between the vanes of the ventilating wheel and to increase an amount of airflow in a desired region of the linear bearing. 19. The method of claim 18, wherein rotating the ventilating wheel includes driving the track of the snowmobile. 20. The method of claim 18, wherein the ventilating wheel comprises: a hub rotatably mounted to the linear bearing; wherein a plurality of the vanes extends radially from the hub; and a rim in rolling engagement with the endless track, the rim circumscribing the vanes and secured to the distal ends thereof.
