A suspension system for supporting a ground engaging member relative to a frame is provided. The suspension system includes a torsion axle assembly including an arm, an axle coupled to the ground engaging member and connected to the arm, a shaft connected to the arm and a tube that is connected to the frame. The tube is configured such that at least a portion of the shaft is received in the tube and supported by the tube for rotation relative to the tube and the frame. A lockout assembly includes a coupling mechanism that is selectively operable to fix the shaft against rotational movement with respect to the tube.

Vehicles, systems and methods for providing articulating two section vehicles with tracks, and a front body attached superstructure with telescopic forklift, for use on all terrain condition applications. The vehicle can include front and rear track assemblies that can tilt up and down while traveling over different ground surfaces. Each of the track assemblies can have rotatable articulating/oscillating track wheels which can traverse different contoured surfaces. The right and left tracks on both the front and rear track assemblies can separately extend outward and inward from underneath the vehicles to add stability to the vehicles. The cab can be raised and lowered to add greater visibility for the operator. Hydraulics can be used for raising and lowering the extendable boom and operator cab, as well as controlling the body articulating hinge, the articulating tracks and the tilting controls for the front track assembly.

Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

A track driven work machine including a body, a first track laying assembly pivotally connected to the body, and a second track laying assembly pivotally connected to the body. The second track laying assembly is spaced apart from the first track laying assembly in a direction transverse to a running direction of the track laying assemblies. In order to navigate uneven grounds, the track driven work machine includes a hydraulic system for synchronizing pivotal movement of the first and second track laying assembly and which is configured to pivot the second track laying assembly in an opposite direction to the first track laying assembly when the first track laying assembly is pivoted in a first direction, and vice versa.

A vehicle comprises a chassis, a seat, a motor, an endless drive track, and a rear suspension assembly supporting the endless drive track. The rear suspension assembly includes a left slide and right slide rail, at least one rear suspension arm being operatively pivotally connected to one of the slide rails and the chassis, with at least one coupling block being connected thereto. A rear stopper is connected to one of the slide rails, the rear stopper being disposed within a range of motion of the at least one coupling block in a first position and being disposed out of the range of motion of the at least one coupling block in a second position. The vehicle includes a control cable and an actuator, the rear stopper moving between the first and second positions when moving the actuator between first and second actuator positions.

A track assembly for a vehicle includes: a frame; a plurality of track-contacting wheels; an endless track disposed around the track-contacting wheels; a rotation limiting device for limiting rotation of the track assembly relative to a vehicle frame; a connection bracket for connecting the rotation limiting device to the frame; and a bushing assembly slidably connecting a device connecting end of the connection bracket to an elongate support of the rotation limiting device. The bushing assembly includes an inner bushing slidably mounted to the elongate support, an outer bushing affixed to the device connecting end, and a resilient element connected between the bushings. The resilient element is resiliently deformable such that: the inner bushing is rotatable relative to the outer bushing such that an inner bushing axis can be angled relative to an outer bushing axis; and the inner bushing is axially movable relative to the outer bushing.

The present invention provides a ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof. Through cooperation of a push rod motor and a rotating pair, multi-angle cutting is achieved, and energy consumption needed by mowing operation is reduced. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower. The use of a right-angle bypassing obstacle avoidance mode realizes precise obstacle avoidance of the mower, and achieves the operation purpose of not excessively relying on operators.
