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.

A track for traction of a vehicle, such as an all-terrain vehicle (ATV), a snowmobile, an agricultural vehicle, etc. The track may have rigidity (i.e., stiffness) characteristics to enhance its traction, floatation, and/or other aspects of its performance. For example, in some embodiments, a lateral bending stiffness of a carcass of the track may be symmetric while a longitudinal bending stiffness of the carcass of the track may be asymmetric.

A resistance to wear, edge-cutting or other deterioration of a track for a vehicle and/or other aspects of the track may be enhanced, including by enhancing internal reinforcements (e.g., cores) of the track, such as by providing certain flexibility characteristics to these internal reinforcements of the track, and/or by monitoring the track and controlling the vehicle, notifying a user, etc.

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 described.

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 track system includes an attachment assembly including at least one of a first pivot defining a roll pivot axis, a second pivot defining a pitch pivot axis, and a third pivot defining a yaw pivot axis of the track system. A frame assembly is disposed laterally outwardly from the attachment assembly and connected to the attachment assembly. The track system further includes at least one actuator for pivoting the frame assembly about at least one of the roll and yaw pivot axes, and at least one monitoring for determining, at least indirectly, at least one of a state of the track system and a ground surface condition. The at least one monitoring sensor is communicating with a track system controller to control the operation of the at least one actuator based on the at least one of the state of the track system and the ground surface condition.

A track system for traction of a vehicle (e.g., a compact track loader or other construction vehicle) which may be designed to improve ride quality (e.g., reduce vibrations) for an operator and/or enhance other aspects of its performance or that of the vehicle. For example, a track of the track system may be frictionally driven and without transversal rigid parts (e.g., metallic cores). Also, power generation and transmission functions may be implemented by the track system. For instance, a motor and a transmission may be at least mostly contained within the track system.

One general aspect includes a tethered temperature sensor for use within a vehicle track. The tethered temperature sensor includes one or more sensors for measuring temperature located in a high strain and high temperature region of the vehicle track. The sensor also includes circuitry configured to control and/or monitor the one or more sensors and located in a low strain and low temperature region of the vehicle track. The sensor also includes a housing to contain the circuitry. The sensor also includes an encapsulating material that fills an interior of the housing.

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 tread pattern for a vehicle track, such as an endless track for earth-moving equipment, comprises a plurality of blocks. Each block includes two lateral traction portions extending in substantially opposite directions. The two lateral traction portions are longitudinally aligned and each define a pair of walls defining a plurality of steps. In some examples, each lateral traction portion may define an L-shape. For example, the lateral traction portions of each block may define a protrusion to define the L shape, and, in some examples, the protrusions may extend in opposite longitudinal directions. In some examples, the lateral traction portions of each block may be the same shape, where one lateral traction portion may be oriented at about 180 degrees relative to the other lateral traction portion.
