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.

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).

A novel sprocket for a track drive of a mobile robot may allow for some deformation of the track so that the track better conforms to the surface on which the robot travels. The novel sprocket also may prevent excessive track deformation or deflection that may result in undesirable de-tracking.

A track component for use with a track assembly includes a gyro sensor that monitors a track wrap angle of the track chain assembly about the idler wheel, or the drive sprocket.

A farm implement is provided having a frame and first and second track assemblies for assisting in moving the farm implement along a ground surface in a line of travel. The first track assembly and the second track assembly are positioned on opposite lateral sides of the frame. The first track assembly has a first track frame, a first idler wheel, and a first brake assembly. The first idler wheel has an inboard side facing toward a center of the first track frame and an outboard side facing away from the center the first track frame. The first brake assembly has a first disc coupled to the first idler wheel on the outboard side of the first idler wheel, a first caliper couplable to first and second sides of the first disc, and a first torque arm coupled to the first track frame and a spindle of the first idler wheel. The first caliper is mounted on the first torque arm, and the first caliper is configured to clamp down on the first and second sides of the first disc in order to slow and/or stop rotation of the first idler wheel.

A tensioner for adjusting a tension in an endless track of a track system is disclosed. The tensioner includes a resilient portion and a wheel connecting portion. The resilient portion is connectable to a frame of the track system, the resilient portion being oriented generally vertically. The wheel connecting portion is pivotally connectable to the frame of the track system, is connected to the resilient portion and is configured to connect to an idler wheel assembly. A track system having the tensioner is also disclosed.

A crawler traveling device includes a first wheel; a second wheel spaced from the first wheel; a support frame that supports the first wheel and the second wheel; a third wheel disposed above the support frame; an endless crawler wound around the first wheel, the second wheel, and the third wheel; and a vehicle-height changing mechanism that changes a position of the support frame in the vertical direction with respect to the third wheel. The vehicle-height changing mechanism has an actuator that is capable of contracting in the vertical direction and that changes the position of the support frame in the vertical direction with respect to the third wheel.
