A track system for a vehicle having a rear swing arm that is movable between a compressed suspension position and an extended suspension position. The track system has a frame and a dynamic traction device. The frame is pivotably attachable to the swing arm. The dynamic traction device has at least two elongate portions, one of which is movable relative to the other between a retracted position and an extended position and biased toward the retracted position. In use, the elongate portions interconnect the vehicle and the frame. When the vehicle is lifted off terrain, during at least a part of a movement of the swing arm from the compressed suspension position toward the extended suspension position, the dynamic traction device applies a torque to the frame and thereby changes a longitudinal angular position of the frame counter-clockwise relative to a left side of the vehicle.

A track hitching structure is for a wheeled crane and the wheeled crane, and includes a vehicle frame and a connecting cross beam. The first end of the connecting cross beam is connected with a track. The second end of the connecting cross beam is connected with the vehicle frame. The second end of the connecting cross beam is higher than the first end of the connecting cross beam. The vehicle frame is connected with the track by the connecting cross beam with one high end and one low end, so the long-distance force transfer from the track to the race of the vehicle frame can be handled, then the shortcomings of tedious structure, large size, large weight and the like of the connecting device caused by a horizontal connecting cross beam are avoided, and the reliability and the working performance of the entire crane are improved.

A vehicle comprising at least a first wheel (6) mounted in a first side area of the vehicle and a second wheel (6′) mounted in a second side area of the vehicle is disclosed. The vehicle comprises a track device (8) configured to be brought into engagement with the ground (10). The vehicle comprises a control member (32) configured to adjust the pressure with which the track device engages the ground, wherein the pressure is determined on the basis of measurements performed by one or more detection members configured to detect one or more variable parameters of the vehicle or external information received by the vehicle.

Provided is a track drive for outdoor power equipment including a support frame and a drive axle configured to attach to an associated drive hub. A hub bearing is mounted on the drive axle and the support frame enabling the drive axle to rotate relative to the support frame. A drive sprocket is attached to the drive axle and includes an interior half sprocket and an exterior half sprocket. The half sprockets are located on either side of the support frame. Drive teeth are spaced radially about the drive sprocket. The drive sprocket is movably engaged with an endless track to transmit force to rotate the endless track and propel the outdoor power equipment. A kit for adding or replacing a track drive of outdoor power equipment is also provided.

Example techniques have been presented for providing tracked vehicles with deployable towing wheels. Such techniques involve a track vehicle having a vehicle body, a track coupled to the vehicle body, and a wheel assembly coupled to the vehicle body. The wheel assembly includes a wheel and is operable to assume a towing position in which at least a portion of the wheel extends below the track and enables the tracked vehicle to be towed on the wheel without the track making ground contact.

The present invention generally relates to vehicle and machinery in agriculture, construction, forestry, mining and powersport. It further generally relates to track systems and traction assemblies used with such vehicles. The track assembly includes components having particular features that, alone or in combination, participate in decreasing the vibrations 5 undergone by the vehicle. According to embodiments, split frames are used with suspension, tandem subassemblies, “tridem subassemblies”, adjustable damping components, drive shaft openings, lowering of resulting the track band tension and rosta assemblies.

Track system for a vehicle having a chassis and a drive shaft extending laterally outwardly from the chassis includes: An attachment assembly having a leading pivot and a trailing pivot. A multi-member frame assembly including: a leading frame member pivotably connected to the attachment assembly via the leading pivot for pivoting about a leading pivot axis; a trailing frame member pivotably connected to the attachment assembly via the trailing pivot for pivoting about a trailing pivot axis; a leading wheel-bearing frame member at least indirectly pivotably connected to the leading frame member; a trailing wheel-bearing frame member at least indirectly pivotably connected to the trailing frame member. A damper interconnecting the leading frame member and the trailing frame member. A leading idler wheel assembly; a trailing idler wheel assembly; support wheel assemblies; a gearbox; a sprocket wheel; and an endless track.
