A tracked vehicle is provided. The tracked vehicle includes a frame, a driving mechanism installed in the frame, and two track wheels respectively arranged on the left and right sides of the frame. The driving mechanism drives the track wheels to rotate. The track wheel includes a track body, a first main support, a second main support and a third main support provided in the track body. The first main support, the second main support and the third main support are connected to the vehicle frame through the first, second and third connecting rods respectively. The second main support is provided with an auxiliary support frame having one end hinged to the second main support, and the other end of the auxiliary support frame is provided with a first roller contacting with the inner side of the track body.

A vehicle includes a chassis, an engine coupled to the chassis, a power source coupled to the chassis, and a track assembly. The track assembly includes an electric motor coupled to the chassis, a first drive wheel coupled to the electric motor and pivotally coupled to the chassis, a second drive wheel coupled to the engine and pivotally coupled to the chassis, and a track engaging the first drive wheel and the second drive wheel. The engine is configured to provide mechanical energy to the second drive wheel to drive the track and propel the vehicle. The electric motor is configured to receive electrical energy from the power source and provide mechanical energy to the first drive wheel to drive the track and propel the vehicle.

A track assembly mounted to a rotating wheel drive of a vehicle that includes a frame with inboard and outboard frame members having a center gap between them. A bearing housing is mounted to the outboard frame member. A hub adaptor has a peripheral wall forming a hollow interior that receives the wheel drive. Separate annular flanges are connected to and extend away from inner and outer surfaces of the peripheral wall and connect to the wheel drive and a sprocket surrounding the hub adaptor. As the hub adaptor rotates within the bearing housing, the sprocket rotates within the center gap of the frame. Idler are rotatably connected to opposed ends of the frame. An endless track is routed over the sprocket and around the idlers. The endless track engages with and is driven by rotation of the sprocket in order to circulate the track about the frame in a generally triangular path.

A track system for a vehicle on a ground, wherein the track system may be designed to enhance ride quality (e.g., comfort), stability, load distribution on the ground, manoeuvrability (e.g., steerability), adaptability to ground and/or working conditions, and/or other aspects of the track system and/or the vehicle, such as by being movable relative to a frame of the vehicle (e.g., horizontally, vertically, and/or pivotally), resiliently supporting wheels of the track system (e.g., with elastomeric bushings or other components), and/or varying how much of the track engages the ground (e.g., reducing that to facilitate turning).

In accordance with the present disclosure, a track chain assembly for a work vehicle may comprise of a link set, a unitary link, and a bushing assembly. The link set may include a first link and a second link. The unitary link may include a single link. The bushing assembly may couple the link set and the unitary link for relative rotation between the link set and the unitary link.
