An undercarriage assembly for a track-type vehicle is described. The assembly comprises at least one closed-ring rubber belt, internally provided with a continuous insert made of a plurality of metal elements embedded in the rubber mass that constitutes the rubber belt. The metal elements are positioned at a fixed and predetermined distance apart from one another, which determines the pitch of the rubber belt. The rubber belt further encloses therein one or more reinforcing elements, each consisting of a metal wire bundle oriented according to an axis substantially parallel to the longitudinal development central axis of the rubber belt. The assembly also comprises a plurality of rolling elements of each rubber belt, consisting of at least one drive sprocket, configured to mesh with the metal elements of the continuous insert and to rotationally move the respective rubber belt, of at least one idler wheel and of a plurality of rollers. Each drive sprocket consists of a gear integral with at least one disk arranged on a plane parallel to the development plane of the gear. An annular groove is interposed between the gear and each disk and each disk is provided with a smooth circumferential surface that engages with a predefined portion of the inner surface of the rubber belt, so as to absorb one part of the contacting forces that are generated between the rubber belt and the entire plurality of rolling elements of the rubber belt.

A track system for traction of a vehicle (e.g., a snowmobile, an all-terrain vehicle (ATV) etc.). The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may have various features to enhance its traction, floatation, and/or other aspects of its performance, including, for example, a lightweight design, enhanced tractive effects, an enhanced heat management capability, an enhanced resistance to lateral skidding (e.g., on a side hill), an adaptive capability to adapt itself to different conditions (e.g., ground conditions, such as different types of snow, soil, etc.; and/or other conditions), an adjustability of a contact area of its track with the ground, and/or other features.

Endless vehicle tracks including a body having an outer surface formed of an elastomeric material displaying a series of ground engaging profiles longitudinally spaced along the outer surface, and an inner surface formed a urethane reinforcement material. The inner surface generally displays a series of longitudinally spaced guide-drive lugs for retaining the track on the vehicle and/or driving the vehicle. The urethane reinforcement defines the inner surface of the body. The urethane reinforcement may define wheel path regions of the body, and the urethane reinforcement may even form the guide-drive lugs. The endless vehicle track may further include a fabric reinforcement layer disposed beneath or upon the outer surface of the upper face of the guide-drive lugs. The urethane reinforcement is formed from an admixture including a castable urethane material liquid which fills a mold and hardens to form the urethane reinforcement. The mold also includes a metal reinforcement therein.

A vehicle includes a plurality of track systems, a fluid pump, a plurality of fluid lines fluidly connecting the fluid pump to at least some of the tires of the wheels of each of the track systems, a plurality of pneumatic inflation actuators, a plurality of pneumatic deflation actuators, and a system controller. The system controller is in electronic communication with the fluid pump, the plurality of pneumatic inflation actuators, and the plurality of pneumatic deflation actuators. The system controller is operable to selectively adjust fluid pressure in select ones of the wheels of any one of the track systems of the vehicle by actuating corresponding ones of the plurality of pneumatic inflation actuators and the plurality of pneumatic deflation actuators. A track system has at least one of the leading idler wheels, trailing idler wheels, and mid-roller wheels including a tire containing a fluid.

An endless track belt for a submersible, autonomous vehicle is disclosed. The track belt includes an outer surface with raised track elements that are configured to both engage a supporting surface and selectively receive external grip elements configured to engage the supporting surface. The track belt also includes an inner surface with continuous, annular ridges. The continuous ridges are configured to secure the endless track belt to a drive pulley in a manner that prevents lateral movement while allowing for some longitudinal slip during rotational movement of the belt.

Monitoring vehicles comprising track systems or tires to obtain information regarding the vehicle, including information regarding the track systems or tires, such as an indication of a level of wear, a rupture like a break, a puncture, chunking, de-bonding, etc., which can be used for various purposes, such as, for example, to convey the information to a user (e.g., the operator); control the vehicle (e.g., a speed of the vehicle, operation of a work implement, etc.); transmit the information to a remote party (e.g., a provider such as a manufacturer or distributor of the track systems or tires); etc.

A tracked powered chair is described. A side drive assembly comprises a powered sprocket, a forward non-powered two wheel bogey, and a rearward non-powered two wheel bogey. Each bogey has a respective pivot member pivotally fastened at a first pivot member end between the first and second bogey wheels, and a second pivot member end fastened to the frame such that the forward and rearward bogey each pivot independently from one another around its respective pivot member. The geometry of the drive assembly creates a non-isosceles shaped triangular appearance (no two sides are of equal length).

A work vehicle may include a load sensor, an engine, a drive train driven by the engine and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further comprise a temperature sensor configured to sense a temperature and a vehicle control system configured to receive the sensed temperature and a vehicle load from the load sensor. The vehicle control system is configured to output a work speed vehicle alert based upon a combination of the temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor.

An oscillation limited driven steering track assembly includes a track mechanism coupled to and driven by a hydraulic motor. The motor is pivotally secured about a steering axis to a stub axle which partially supports a land vehicle. A longitudinally extensible and retractable apparatus extends between the track mechanism and the stub axle. One end of the apparatus is pivotally secured to a post secured to and extending from the track mechanism parallel with the motor shaft axis of rotation. A yoke is provided between the apparatus other end and pivotally secures the apparatus to the stub axle about the steering axis and, also, about a pivot axis perpendicular to the steering axis. Oscillation of the track mechanism about the motor shaft is limited by the apparatus. Simultaneously, the apparatus does not interfere with the track mechanism while the mechanism is rotated about the steering axis for steering the vehicle.

A tracked vehicle with a chassis comprising an upper frame structure connected to a lower frame structure, the lower frame structure spanning a longitudinal distance along a longitudinal direction of the vehicle, wherein over a first portion of the longitudinal distance, the lower frame structure overlaps with the upper frame structure and wherein over a second portion of the longitudinal distance, the lower frame structure does not overlap with the upper frame structure. The tracked vehicle may also comprise an operator cabin, power plant mounted to the upper frame structure and a plurality of track assemblies for traction of the tracked vehicle. Each track assembly is mounted to the lower frame structure of the chassis and comprises a drive wheel; an end wheel; and a plurality of support wheels therebetween; and an endless track disposed around the plurality of wheels for engaging a ground on which the tracked vehicle travels.
