A track assembly is to be mounted on a drive axle of a vehicle. The track assembly has a frame, at least one leading idler wheel mounted to the front of the frame for rotation about a transverse leading idler wheel axis, at least one trailing idler wheel mounted to the rear of the frame for rotation about a traverse trailing idler wheel axis parallel to the leading idler wheel axis, a single drive wheel assembly, and at least two slide rails. The slide rails have corresponding forward-facing portions, central portions, and rearward-facing portions. The forward-facing portions project from the front ends of the central portions by a projection that is greater than a length of the central portions. A vehicle having the track assembly is also encompassed. A kit of track assemblies is also encompassed.

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

Disclosed is a method and device for determining potential damage of an endless track of a tracked vehicle. Said vehicle comprises at least one track assembly comprising a drive wheel member, a tension wheel member, a set of road wheels and said endless track disposed around said wheels. Said endless track is rotated by means of said drive wheel member during drive. The method comprises the steps of: receiving, from at least one sensor, measurement information associated with vibrations of said endless track; based on the information received from said at least one sensor, determining if there is a natural frequency of said endless track and if so determining the natural frequency of said endless track; and, based on the determination associated with natural frequency, determining whether there is a potential damage to the endless track.

A track system for traction of a vehicle (e.g., an all-terrain vehicle (ATV), an agricultural vehicle, etc.) may be designed (e.g., may comprise non-pneumatic tires) to enhance its use or performance and/or that of the vehicle such as, for example, by being lightweight and/or by better handling loads, including, for instance, those resulting from track tension within the track system and/or from unevenness or other aspects of the ground, including encounters (e.g., impacts) with obstacles on the ground (e.g., rocks, portions of trees, debris, bumps, abrupt changes in ground level, etc.). The track system may comprise tension-based non-pneumatic tires.

A track roller unit for an agricultural working machine has at least one first guide roller and one second guide roller. The first guide roller is mounted on a first supporting arm and the second guide roller is mounted on a second supporting arm. At least one support roller is situated between the guide rollers, and a track belt wraps around the guide rollers and the at least one support roller. A hydropneumatic damping element is assigned to at least one guide roller and/or one support roller. At least one regulated restrictor device, which is assigned to a damping element, is provided and is designed in such a way that its flow resistance is adjustable during the operation of the track roller unit.

A vehicle platform comprises a central body that can support one or more implement configurations, such as sprayer booms, or planting row units. A plurality of adjustable legs extends downward from the central body. An arm assembly has a first end and a second end opposite the first end. The first end is pivotably coupled the central body and the second end coupled to a support beam. A plurality of nozzle assemblies is supported from the support beam. An arm actuator is arranged to control a transverse position of the support beam and the nozzle assemblies with respect to a reference point on the central body, such that each nozzle assembly may be aligned with a row of seeds or plants.

Track systems for traction of an off-road vehicle, such as an all-terrain vehicle (ATV), a snowmobile, etc. The track systems may have various features to enhance their traction and/or other aspects of their use and/or performance, such as, for example, to better adapt to a suspension of the off-road vehicle (e.g., by compensating for and/or otherwise adapting to alignment settings, namely camber, caster and/or toe), to improve ride quality (e.g., by better absorbing impacts or vibrations within the track systems), and/or to facilitate their installation and/or adjustment on the off-road vehicle.

An idler assembly for a track roller frame includes a housing element having a central cavity, the housing element being connectable to an end of the track roller frame. A yoke element is movably disposed in central cavity and has spaced apart first and second arms, the yoke element is connectable to a longitudinally extending piston in the track roller frame. At least one key element couples the yoke element to the housing element such that the yoke element is movable relative to the housing element. An idler wheel is rotatably supported between the first and second arms.

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.

A tracked vehicle having a track tensioner and a method for adjusting a track tension of a continuous track of a tracked vehicle is disclosed. The track tensioner includes a ball head spindle engaged with an idler wheel support that is engaged with an idler wheel. The idler wheel is engaged with the continuous track. The ball head spindle linearly moves relative to a hull of the tracked vehicle to increase or decrease the tension of the continuous track. A locking device selectively locks the ball head spindle from moving. An energy is supplied to the ball head spindle and the locking device to move or lock the ball head spindle from moving. An operating unit, a control unit, and an energy supply unit control movement of the track tensioner allowing the track tension to be adjusted from the interior of the tracked vehicle.
