摘要:
A traction assembly for replacing a wheel on a vehicle is disclosed. The traction assembly uses a traction band disposed about a sprocket wheel, idler wheels and road wheels for propulsion. The idler wheels and road wheels are pivotally mounted to a support frame which is coupled to the sprocket wheel via a support arm. The support arm is pivotally yet non-drivingly connected to the sprocket wheel and is pivotally connected to the support frame. The support arm is able to pivot forwardly and rearwardly, albeit in a limited fashion, with respect to the support frame. Such forward and rearward pivotal movements allow the weight of the vehicle to be transferred on the trailing portion, i.e. either the front or the rear portion, of the support frame depending on the direction of movement of the vehicle, thereby generally preventing the leading portion from diving or digging into the ground.

The present invention generally provides a wheel replacing traction assembly which uses, for propulsion, a longitudinally extending endless track disposed around and cooperating with a sprocket wheel, idler and/or road wheels and a supporting frame. The endless track generally comprises an inner wheel-engaging surface and an outer ground-engaging surface, the latter being provided with traction lugs. The outer surface further comprises at least one laterally extending portion which also extends along the circumference of the track; the traction lugs located on this laterally extending portion being generally higher than the traction lugs located on the remainder of the outer surface.

This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. The traction assembly pivots around a pivot point located under the traction axle of the vehicle. This pivot point is preferably longitudinally displaced in relation to such axle.

This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. More particularly, the traction assembly comprises a sprocket wheel which has a different size and number of sprocket teeth depending on whether the traction kit replaces the front wheels or the rear wheels of the vehicle. The sprocket wheel of the traction kit can also be configured such that its sprocket teeth are laterally offset. The traction kit can also comprise an anti-torque system that prevent physical contact between the traction kit and the vehicle and that can bias the position of the traction kit in order to improve the steering performance. Finally, the traction assembly can comprise a pivotable extension which lengthens the traction assembly and improves its traction capabilities.

This invention generally relates to track systems and traction assemblies for use as wheel replacement for normally wheeled vehicles. The track system uses a traction band disposed about a sprocket wheel, idler wheels and road wheels for propulsion. The idler wheels and road wheels are typically pivotally mounted to a support frame, itself configured to be coupled to the sprocket wheel via a support member. The track system also comprises a movement limiting link mounted both to the support member and to the vehicle frame. The movement limiting link limits longitudinal and lateral movements of the track system, such as to prevent contact between the track system and the vehicle.

A membrane applying apparatus comprises a wheeled frame adapted to ride on a surface to be covered with the membrane. The rear end of the wheeled frame is generally configured to support a roll of membrane. The apparatus also comprises a roller support frame pivotally mounted to the wheeled frame at the rear end thereof. The roller support frame pivotally supports an idler roller and a pressing roller for respectively guiding and pressing the membrane as the membrane is unrolled during its application. The roller support frame is pivotable between an operative position in which the idler roller and pressing roller respectively guides and presses the membrane, and an inoperative position. In the inoperative position, the roller support frame is pivoted substantially upwardly, thereby providing access to the rear end of the wheeled frame to allow the installation or removal of the roll of membrane.

A drive system has a drive-system frame operatively connectable to a vehicle. The drive-system frame is capable of pivotal movement relative to the longitudinal axis of the vehicle to steer the vehicle. The drive-system frame is incapable of pivotal movement with respect to the frame of the vehicle in a plane parallel to the longitudinal axis and normal to the ground when the vehicle is on flat level terrain and steered straight. A rail is pivotally mounted to the drive-system frame. A ground-engaging endless belt is in sliding engagement with the rail. The belt is operatively connectable to an engine to propel the vehicle. The drive system is operatively connectable to the steering device of the vehicle. A steering angle stopper is disposed on the vehicle such that a steering linkage of the vehicle does not bear a force created when the stopper is engaged. A vehicle is also described.
