Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

A track driven work machine including a body, a first track laying assembly pivotally connected to the body, and a second track laying assembly pivotally connected to the body. The second track laying assembly is spaced apart from the first track laying assembly in a direction transverse to a running direction of the track laying assemblies. In order to navigate uneven grounds, the track driven work machine includes a hydraulic system for synchronizing pivotal movement of the first and second track laying assembly and which is configured to pivot the second track laying assembly in an opposite direction to the first track laying assembly when the first track laying assembly is pivoted in a first direction, and vice versa.

A work machine includes a drive wheel, a drivable track engaged with the drive wheel, a deformable spacer coupled to the drive wheel, and a secondary weight coupled to the deformable spacer. The deformable spacer facilitates oscillation of the secondary weight relative to the drive wheel to limit vibrations of the work machine.

The present invention is related to a track unit for a vehicle, such as an agricultural harvesting combine. The track unit according to a first embodiment of the invention comprises one or more bogies arranged between front and rear guide wheels. The bogies are provided with wheel pairs that are rotatably arranged about a longitudinal axis of the bogie itself, and are thereby capable of adapting individually to transversal oscillations caused by the terrain. Preferably, the bogies are furthermore equipped to adapt to longitudinal oscillations as well, by the longitudinal portion of the bogie being rotatable about a transversal axis. According to a second embodiment, the track unit of the invention is equipped with a cutter, non-rotatably mounted on one or both outer faces of the rear guide wheel, in a position where said wheel is in direct contact with the track, the cutter being configured to cut crop material that is transported upwards between the rear guide wheel and the track when the track unit moves forward.

A track assembly for assisting in moving a farm implement along a ground surface in a line of travel is provided. The track assembly includes a tilt arm comprising front and rear ends. The track assembly includes a camber arm coupled to the tilt arm such that the camber arm permits the tilt arm to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel. The camber arm is located between the front and rear ends of the tilt arm.

The invention is about a crawler driving device, which includes a main frame, a rotary driving wheel designs over the main frame, idler wheels design at both ends of the main frame, as well as multi-pair interval roller wheels mounted at the bottom of the main frame for fore-after driving direction, and crawlers sleeved on the outside of the drive wheels, the idler wheels and the roller sets. The driving wheel of the current invention and the tooth block inside the crawler belt are in meshing structure, so as to drive the crawler belt to rotate. The roller wheels at the bottom can swing up and down during the driving, and supporting the system as well. the roller wheels swing up and down with the rotating shaft in the middle of the mechanical balancers as the fulcrum. In case of uneven terrain, the four sets of roller wheels at the both ends of the balancer can be force-buffered at the same time, so as to ensure the stable ground drive and keeping the vehicle smoothly moving. The idler wheels guide direction, and the tensioning mechanism realizing the tension adjustment between the track and the wheel under the action of the hydro-cylinder.
