This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. More particularly, the traction assembly comprises a sprocket wheel which has a different size and number of sprocket teeth depending on whether the traction kit replaces the front wheels or the rear wheels of the vehicle. The sprocket wheel of the traction kit can also be configured such that its sprocket teeth are laterally offset. The traction kit can also comprise an anti-torque system that prevent physical contact between the traction kit and the vehicle and that can bias the position of the traction kit in order to improve the steering performance. Finally, the traction assembly can comprise a pivotable extension which lengthens the traction assembly and improves its traction capabilities.

This invention relates to an endless traction band that is used to propel band laying vehicles [i.e., vehicles which use endless traction bands rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.]. A novel sprocket wheel having a plurality of radially extending and offset teeth cooperates with an endless traction band having a plurality of holes. Longitudinally consecutive holes define either meshing areas or clip areas. The meshing areas are adapted to be engaged by the sprocket wheel and the clip areas are adapted to support clips.

A bearing for use with a snowmobile track is disclosed. The bearing includes an axle surrounded by a sleeve which is free to rotate when the snowmobile track is driven by the machine. The rails of the suspension systems of the snowmobile ride on the rolling surface resulting in reduced friction. The bearing can be used in a clip on the track or can be included in the track itself. A lubricious coating is utilized to reduce friction between the axle and the sleeve or bushing rotating about the axle.
