A suspension system for a tracked vehicle includes a track roller configured to contact and roll relative to an inner surface of a track. In some examples, the track roller includes an axle member, a roller mounting bracket mechanically connected to the axle member, a frame mounting bracket configured to attach to a frame of the tracked vehicle, and a plurality of coil springs disposed between the roller mounting bracket and the frame mounting bracket. The plurality of coil springs is configured to reduce an impact force transferred from the track roller to the frame of the tracked vehicle.

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.

The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.

A track drive of an agricultural production machine is disclosed. The track drive includes a driving wheel, a front deflection roller, a rear deflection roller, a continuous caterpillar track around the driving wheel and the deflection rollers, and middle rollers between the front and rear deflection roller. The track drive further includes a track frame and a swing frame. Using the swing frame, the track drive pivots about a first axis of the agricultural production machine, and the track frame pivots about a second axis of the swing frame. The second axis is at a distance from the first axis, and a spring system or damper system is positioned between the track frame and the pivot frame. The deflection rollers are positioned on the track frame with the middle rollers positioned on a common support element, which is positioned pivotably about a third axis on the track frame.

A track system for traction of a vehicle, such as an all-terrain vehicle (ATV), an agricultural vehicle, etc. The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may be configured to facilitate adjustment of certain aspects of its operation, including, for example, how it is positioned and/or can move relative to a frame of the vehicle, based on one or more factors, such as, for instance, a user's preferences (e.g., riding style, desire to “feel” the ground, etc.), an environment of the track system (e.g., a profile of the ground, such as a slope or steepness or a levelness of the ground; a compliance of the ground, such as a softness or hardness of the ground, etc.), a state of the track system (e.g., a speed and/or a direction of motion of the track, etc.), a state of the vehicle (e.g., a speed and/or direction of the vehicle, etc.), and/or any other suitable factor. For instance, the track system may comprise a control mechanism configured to adjust an anti-rotation device that is configured to restrict movement of the track system relative to the frame of the vehicle. The control mechanism may be configured to adjust the anti-rotation device in response to a command, which may be input via a user interface or automatically generated by a controller.
