The invention relates to a tracked vehicle comprising a vehicle body and a track assembly pair. Said track assembly pair is arranged to suspendedly support said vehicle body allowing relative movement between said vehicle body and each track assembly (21) of said track assembly pair. Each track assembly (21) comprises a track support beam (22) configured to support a plurality of road wheels (23, 23a), a drive wheel (24), and a motor (110) for operating said drive wheel (24), an endless track (25) being disposed around said road wheels (23, 23a) and drive wheel (24). Said motor (110) is fixedly arranged to said track support beam (22). Said motor (110) is arranged in connection to the drive wheel (24) such that a motor axle essentially coaxially coincides with a centre axis (Z) of the drive wheel (24).

A track kit for a vehicle, the track kit having two track assemblies, each track assembly featuring an endless track and a pinch wheel in contact with the external side of the endless track, the pinch wheel having a pinch wheel axle being rigidly connectable to a chassis of the vehicle.

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 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.

The invention is related to the class of small-scale tracked transportation vehicles, which can be used for towing a person and cargo using a sledge, for example. The motorized towing vehicle comprises a frame supporting a caterpillar drive, a platform supporting an engine with a transmission, a luggage space, an assembly for connecting to the object being towed object, a control device, and an object being towed. The caterpillar drive includes a caterpillar track, a metal subframe, a driven shaft and a driving shaft with pinions, and torsion-type wheel bogie. The control device consists of a steering wheel with handles and controls. The object being towed comprises a driver's workplace. The frame consists of a platform and a rigid framework enclosing the platform along the entire perimeter, including the luggage compartment with an additional luggage space above. The design of the frame and platform is asymmetrical relative to the track because of an extension of the platform in one direction. The subframe is in the form of metal side plates connected to the frame with brackets bent into an S-shape. The subframe plates accommodate a track tightening mechanism in the form of an eccentric and self-aligning bearings. An all-weather hood is used for protecting the engine and luggage space. The road performance of the motor towing vehicle has been improved.

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).

A track for traction of a vehicle, such as an agricultural vehicle, an industrial vehicle (e.g., a construction vehicle), a military vehicle, or another off-road vehicle, is provided. The track comprises a ground-engaging outer surface for engaging the ground and a plurality of traction projections projecting from the ground-engaging outer surface and distributed in a longitudinal direction of the track. The traction projections may be designed to enhance their resistance to deterioration during use. For example, a blowout resistance of each traction projection may be enhanced to prevent or at least reduce a potential for blowout of the traction projection under repeated loads which may induce heat buildup within it. Also, a wear resistance of the traction projection may be enhanced such that the traction projection wears less rapidly. A system for protecting a track against potential occurrence of blowout is also provided.

A crawler monitoring system according to the present disclosure includes a sensor configured to acquire information on a distance between an elastic crawler and a drive wheel and a monitoring member configured to monitor whether a measured value measured based on the information from the sensor is a preset predetermined value or more.

A tracked ATV includes a frame, a track coupled to the frame, and a power source supported by the frame and drivingly coupled to the track. The tracked ATV further includes a steering and drive assembly, which has a first hydraulic pump coupled to the tracks for large radius turns. The steering and drive assembly also has a second hydraulic pump coupled to the tracks for small radius turns.

A core bar for an elastic crawler, the core bar having high durability against a twisting force acting on the core bar during use and an elastic crawler using the core bar are provided. A core bar 30 for an elastic crawler including a long core bar base 31, a pair of projection portions 32L, 32R that project at a center portion in a longitudinal direction of the core bar base 31, and a pair of rail portion 34L, 34R that project from the core bar base 31 on opposite outer sides of the pair of projection portions 32L, 32R and each include a track roller support surface 35 supporting a track roller 56 rolling on an inner circumferential surface of the elastic crawler 10, includes a pair of rail extension portions 36L, 36R that project from the core bar base 31 and each include a top surface 37 formed in such a manner as to continue from the track roller support surface 35, the top surface 37 extending from the rail portion 34L, 34R toward the center side in the longitudinal direction of the core bar base 31.
