A tracked climbing vehicle containing a compliant suspension apparatus to prescribe the distribution of forces on the adhering members in the tracked climbing machine. The compliant suspension apparatus is configured to negotiate irregularities in a climbing surface without the vehicle tracks losing full surface contact and adhesion by distributing the loads from the climbing machine chassis to the adhering traction members in a specific prescribed fashion. The apparatus thus avoids exceeding the allowable force in any adhering traction member and significantly improves the performance of the climbing machine.

Track assemblies (242; 300) for power machines (100; 200) include a track frame (243; 302), including a primary portion (304) and a second portion (306) moveable with respect to the primary portion. A plurality of rollers (248; 316) are positioned along the primary portion of the track frame relative to each other and the center of gravity of the power machine to provide an improved capability to compensate for vibration generated as the power machine moves over a support surface. In some aspects, a portion of a tensioning idler (e.g., 310) is positioned within a cylinder defined by one of the plurality of rollers.

Conveyance vehicles such as snow bikes and snowmobiles having an endless track system driven by a combustion engine are enhanced in performance with a torque assist system. The torque assist system includes an electric motor that is coupled to drive the track in parallel with the original internal combustion engine through either its own track drive, or through the drive system of the engine. The motor can be a spindle drive motor or hub motor. Torque assist is generated through a torque assist throttle input coupled to a motor controller. A battery temperature assist system diverts heated cooling fluid from the engine cooling system to heat the battery through its own heat exchanger. The controller is coupled to a processing device such as a smart phone that executes apps configured to provide parametric data to the controller and to receive parametric data from the controller through a user interface.

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.

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 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.
