A track assembly for providing traction to an off-road vehicle, such as an agricultural vehicle, a construction vehicle, or another work vehicle, in which the track assembly may comprise a suspension between a frame of the track assembly and a bogie carrying roller wheels of the track assembly.

A track assembly for providing traction to an off-road vehicle, such as an agricultural vehicle, a construction vehicle, or another work vehicle, in which the track assembly may comprise a suspension between a frame of the track assembly and a bogie carrying roller wheels of the track assembly.

The invention relates to a track assembly for a tracked vehicle. Said track assembly comprises a track support beam configured to support road wheels, a drive wheel member, and a drive arrangement for drive wheel member operation and an endless track disposed around said road wheels and drive wheel member. Said drive arrangement comprises a brake arrangement for braking the drive wheel member, and a drive axle coaxially arranged relative to a centre axis of said drive wheel member for rotating said drive wheel member. Said brake arrangement is configured to be journaled in bearings in connection to a portion of the drive axle. Said brake arrangement comprises a torque arm configured to be connected to said track support beam so as to essentially prevent rotation of a brake housing of said brake arrangement about said centre axis.

In one aspect, a system for adjusting a position of an idler wheel of a track assembly for a work vehicle relative to the ground may include a track assembly having a first idler wheel. The system may also include a first actuator configured to move the first idler wheel between a lowered position relative to the ground and a raised position relative to the ground. Furthermore, the system may include a controller communicatively coupled to the first actuator. The controller may be configured to receive inputs indicative of an anticipated or actual change in a direction of travel of the work vehicle. The controller may further be configured to control the first actuator to move the first idler wheel from the lowered position to the raised position in response to determining that the work vehicle has initiated a change in the direction of travel.

Disclosed is an unmanned vehicle suitable for mountains and hills and an attitude adjustment method, relating to the technical field of intelligent agricultural equipment in mountainous and hilly regions. The unmanned vehicle includes a frame and side arms arranged on both sides of the frame. The lower end of each side arm is provided with a traveling device, and each side arm is provided with an attitude adjustment device. The attitude adjustment devices are respectively connected to both sides of the frame, and the attitude adjustment devices are configured to adjust an attitude of the frame. The frame is provided with a control structure and a triaxial angle sensor, both of which are electrically connected to the control structure, and the triaxial angle sensor is configured to detect an angle of inclination of the frame. The unmanned vehicle can achieve the slope adaptation in the mountainous and hilly areas.
