Abstract: An endless snowmobile track for traction of a snowmobile. The endless snowmobile track comprises a ground-engaging outer side for engaging the ground on which the snowmobile travels and an inner side for engaging at least one drive wheel of the snowmobile. The inner side comprises a friction drive surface for frictional engagement with the at least one drive wheel such that, when each of the at least one drive wheel rotates, friction between the friction drive surface and the at least one drive wheel moves the endless snowmobile track to propel the snowmobile on the ground. An endless all-terrain vehicle (ATV) track for traction of an ATV is also provided.

Abstract: There is provided a stud mount comprising a stud-receiving passage studs are inserted by force. Each stud is anchored in a stud mount to a reinforced portion of the track independently of reinforcing rods thereof, thereby allowing a reduced complexity of machining of a stud mounting cylinder and strengthened mechanical and traction properties of the track.

Abstract: An endless track for traction of a vehicle, such as a construction vehicle, an agricultural vehicle, a forestry vehicle or a military vehicle. The endless track has an enhanced elastomeric material curing capability. In one embodiment, each of a plurality of elastomeric projections of the endless track, such as guide/drive projections or traction projections, comprises elastomeric material defining a cavity to enhance a curing process during manufacturing of the endless track. The cavity may be shaped such that, during the curing process, a heat conductor positioned in the cavity conducts heat from the heat conductor to the elastomeric material of the projection.

Abstract: An endless track for traction of a vehicle, such as a construction vehicle, an agricultural vehicle, a forestry vehicle or a military vehicle. In one embodiment, the endless track comprises a plurality of track sections connected to one another. Each track section comprises: a body having an inner side for facing wheels of the vehicle and a ground-engaging outer side for engaging the ground; and a connector for connecting the track section to an adjacent one of the track sections at a joint, the joint being flexible in a widthwise direction of the endless track.

Abstract: A vehicle with a frame connecting a driver wheel, an idler wheel and mid-roller wheels, an endless track belt being tensioned around the driver wheel and the idler wheel and being in contact with the mid-roller wheels on a lower run thereof, the mid-roller wheels being arranged in bogies, including a front bogie having a first pivot axis, a middle bogie and a rear bogie arranged in tandem having a second pivot axis, wherein the first pivot axis and said second pivot axis act as load transfer pivots.

Abstract: A track assembly for providing traction to an all-terrain vehicle (ATV) or other tracked vehicle. The track assembly may comprise a wheel device for contacting an inner side of an endless track such that a longitudinal end segment of the endless track turns around the wheel device. The wheel device allows a change in curvature of the longitudinal end segment of the endless track when the longitudinal end segment of the endless track contacts an obstacle on the ground. In some embodiments, the wheel device may comprise a resilient wheel that is elastically deformable. In other embodiments, the wheel device may comprise a wheel carrier carrying a plurality of carried wheels.

Abstract: A track formed of a molded rubber base sandwiching a cord layer, followed by a cross bar and a single layer of ply fabric extending longitudinally of the track.

Abstract: A rubber track for tracked vehicles, comprising a rubber belt with an inner surface and a ground-engaging surface, the ground-engaging surface comprising a series of traction lugs spaced apart in a longitudinal direction of the track at a first pitch, the inner surface provided with a series of drive lugs spaced apart in the longitudinal direction of the track at a second pitch, wherein the rubber belt comprises at most one reinforcing rod, embedded in a rubber material thereof and extending transversally substantially over an entire width of the track, at every two traction lugs.

Abstract: An endless belt body for a track assembly, comprising through holes, between traction lugs of the ground-engaging surface thereof, along a length thereof, located in at least one of: i) the central region of a width of the endless belt body, and ii) on the lateral parts of the width of the endless belt body.

Abstract: Treads for a track having at least one face, front or rear, that is uneven due to the presence of steps, indentations, or projections for example, thus providing a multi-edge ground contacting surface. The treads may further have an increasing cross section from a top part thereof to a bottom part thereof, the top pan having a section smaller than the bottom part.

Abstract: An endless belt body for a track assembly, comprising through holes, between traction lugs of the ground-engaging surface thereof, along a length thereof, located in at least one of: i) the central region of a width of the endless belt body, and ii) on the lateral parts of the width of the endless belt body.

Abstract: The present invention provides an endless track belt allowing an enhanced traction of a tracked vehicle over a range of surface conditions, by providing tread on the ground-engaging surface having a top part and a bottom part, the top part being flexible, whereas the bottom part is rigid. On a loose underground such as powder snow, the flexible top part of the tread bends to apply a compacting action on the underground, while, on a packed underground, the rigid bottom part of the tread has a grabbing action on the underground.

Abstract: A wheel structure driven by an endless track belt tensioned around a drive wheel and an idler wheel thereof, comprising a plurality of supporting mid-roller wheels provided between the drive wheel and the idler wheel, a second endless belt being tensioned around this plurality of mid-rollers.

Abstract: There is provided a wheel assembly and associated method of mounting wheels about a hub, by providing a hub comprising a shoulder having a clearing space allowing a wheel introduced by one side of the hub to be pivoted to an opposite side thereof.

Abstract: A one-piece track comprising, along each opposite edge thereof, regions having an accordion-type structure, which allows these regions to have a variable longitudinal length along each opposite edge of the track according to a movement of the tracked vehicle and to a corresponding inclination of the track.

Abstract: A track for a tracked-vehicle in which the driving power is transferred from the motor to the track through the driving sprocket via the profiles of the ground-contacting surface of the track, wherein the ground engaging surface is reinforced, at least in portions thereof where the sprocket passes, by reinforcing a base of the profiles in these portions.

Abstract: An endless track for a recreational vehicle, such as a snowmobile on all-terrain vehicle, is formed of an endless body made of rubber material having a ground engaging side and an inner side, the outer side displaying a series of longitudinally spaced profiles extending along the track; the track is characterized in that the rubber material of one profile has a hardness which is greater than the hardness of the rubber material of one or more of the succeeding profiles.

Abstract: There is provided an endless track belt laterally reinforced by embedding high elongation cords on each peripheral sides of the endless track belt to prevent cuts formed on the periphery of the belt by sharp objects from propagating further towards the inner width of the endless track belt.

Abstract: The ground engaging outer side of an endless track of a track-propelled vehicle displays a series of longitudinally spaced profiles which are defined by a central portion and two opposite lateral portions; the rubber material of the lateral portions of the body has a hardness which is greater than the hardness of the rubber material of the central portion of the body.
