Abstract
Abstract A bogie wheel system adapted for use with snowmobiles is provided herein. The bogie wheel system comprises elongate first members rotatably mounted at one end on a support means and coil springs normally urging the other end of the first members downwardly. Second members are aligned with the first members and aligned with the track of the snowmobile and have axles mounted transversely of the track with bogie wheels rotatably mounted thereon. Resilient members are disposed between the first members and the second members and means are provided for securing them in aligned relation.

Claim 1
Independent Claim
242 words
Bogie wheel means for a snowmobile-type vehicle having a drivable, endless track for motive power and means for driving the track, the track having a first portion thereof normally in contact with the ground and a second portion thereof suspended over the first portion, said bogie wheel means comprising: horizontally disposed support means formed on said vehicle between the first and second portions of the track and disposed transversely of the track; elongate first members mounted proximate one end thereof on said support means and extending rearwardly thereof, said first members being rotatable about the longitudinal axis of said support means; spring means normally urging the other ends of said first members downwardly; second members aligned with the track, one of said second members being aligned with each of said first members; at least one resilient member disposed between each said first member and its aligned second member, said at least one resilient member having an upper end and a lower end, said upper end secured to said first member and said lower end secured to said second member; means securing said first members, said resilient members, and said second members in aligned relation; at least two horizontally disposed axles mounted on each of said second members and disposed transversely of the track; bogie wheels, at least one of said wheels being rotatably mounted on each of said axles and normally contacting the upper surface of the first portion of the track.
