Abstract: A track system for traction of an off-road vehicle such as a snowmobile or an all-terrain vehicle (ATV). The track system comprises a track-engaging assembly and a track disposed around the track-engaging assembly. The track system may be configured to have a reduced noise profile so as to generate less noise, enhanced track rigidity characteristics to improve its traction and floatation, and/or other features improving use and performance of the off-road vehicle.

Abstract: A treaded traction device for model vehicles is provided. The treaded traction device includes a biasing assembly and a tensioning assembly. The biasing assembly includes a first bias support fixed relative to a vehicle hub and a second bias support fixed relative to a traction hub. The biasing assembly also includes a coil and a dampener attached to the first and second bias supports. The treaded traction device is biased to result in one end being lower than another end. The tensioning assembly includes an idler wheel and a first and second tension support. The tension supports may be rotated to move the idler wheel, releasing tension on a surrounding tread. When the tension is released, the surrounding tread may be removed or replaced.

Abstract: A track assembly is to be mounted on a drive axle of a vehicle. The track assembly has a frame, at least one leading idler wheel mounted to the front of the frame for rotation about a transverse leading idler wheel axis, at least one trailing idler wheel mounted to the rear of the frame for rotation about a traverse trailing idler wheel axis parallel to the leading idler wheel axis, and a single drive wheel assembly. The drive wheel assembly includes a sub-frame removably securable to the frame in any one of a plurality of longitudinal securement positions on the frame, and a drive wheel rotationally mounted on the sub-frame for rotation about a drive wheel axis. The drive wheel is operatively connectable to the drive axle of the vehicle. A pair of track assemblies is also described. A vehicle having the pair of track assemblies is also described.

Abstract: A guard assembly is provided for use with a track assembly for a vehicle. The guard assembly includes a guard body having a rigid portion made of a first polymeric material and a flexible portion made of a second polymeric material different from the first polymeric material. The first polymeric material has a greater modulus of elasticity than the second polymeric material. A vehicle including a guard assembly, namely including a guard body is also contemplated.

Abstract: Track systems for traction of a vehicle in which a spacing of laterally-adjacent ones of the track systems in a widthwise direction of the vehicle is adjustable. This may facilitate use of the vehicle in different conditions (e.g., in different field configurations, such as in different configurations of row crops, where the vehicle is an agricultural vehicle). For instance, the spacing of the laterally-adjacent ones of the track systems may be adjustable while the laterally-adjacent ones of the track systems are connected to a powertrain of the vehicle and/or without requiring use of additional parts (e.g. spacers).

Abstract: A track drive for outdoor power equipment has a support frame with a centerline and a hub bearing attached to the support frame. A drive sprocket having a nesting interior half and exterior half is attached to the hub bearing, which enables the drive sprocket to rotate relative to the support frame. The drive sprocket is attached to an associated drive hub of a piece of outdoor power equipment. Drive sprocket teeth are spaced radially about the drive sprocket, with a first set of drive teeth attached to the interior half sprocket and located on an interior side of the support frame. A second set of drive teeth are attached to the exterior half sprocket and located on an exterior side of the support frame. The drive sprocket transmits a rotational force to an endless track to rotate the endless track and propel the outdoor power equipment.
