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.

A track system comprising a dynamic tensioning device located between an idler wheel and the support frame as to apply proper tension in the track. The dynamic tensioning device is adapted to block at its current length upon the occurrence of a determined condition. The dynamic tensioner is adapted to substantially maintain its length when an acceleration and or deceleration of the track system reaches a predetermined value. For instance, such characteristic is relevant in an event of emergency braking. A dynamic tensioner would become contracted and the tension in the endless track would become too low. A low tension could cause the endless track to ratchet.

A mobile farm implement includes a track assembly with a plurality of arms that are pivotally coupled to support idler wheels and bogie wheels such that the track assembly is able to better conform to the terrain when the implement is towed behind a tractor or otherwise moved.

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 support structure having an axle and a multi-linkage assembly including first and second linkages for connecting at least one support wheel assembly to a frame member of a track system is disclosed. The first and second linkages are connectable to the frame member and the axle, and cooperatively define an imaginary pivot, which defines a pivot axis about which the axle can pivot due to the multi-linkage assembly. A support structure having an axle, at least one resilient body, and frame and axle clamping assemblies is also disclosed. The at least one resilient body, connectable to the frame member and the axle by the frame and axle clamping assemblies, defines an imaginary pivot, which defines a pivot axis. The at least one resilient body is deformable such that the axle is pivotable about the pivot axis. Track systems having the support structures and resilient assemblies are also disclosed.

A support structure having at least one connecting member, a shaft, at least one axle transversally connected to the shaft and at least one resilient member for connecting the at least one support wheel assembly to a frame of a track system is disclosed. The at least one resilient body defines an aperture, in which one of first and second portions of the shaft is received, and has an inner portion that is fixedly connected to the one of first and second portions and an outer portion that is fixedly connected to the at least one connecting member. Upon resilient deformation of the at least one resilient member, the shaft is rotatable, and the at least one axle is pivotable, about the longitudinal axis. The at least one resilient body biases the shaft toward an initial position upon rotation thereof. A track system having the support structure is also disclosed.
