Abstract

An adjustable pivot module for an endless track which aims at optimizing the adjustment of a track assembly, regardless of the geometry of the track assembly. The adjustable pivot module may be configured to be mounted in different positions to account for geometric and performance constraints. The pivot pin module comprises a housing adapted to pivotally receive a pivot pin from a vehicle or equipment. The module is adapted to provide different offset values with regard to a horizontal axis and/or a vertical axis.

First claim

1 ) A track system for a vehicle, the track system comprising:
a support frame pivotally mounted to an attachment point of the vehicle; a plurality of wheels pivotally mounted on the support frame; and an endless track disposed around the plurality of wheels, the endless track defining an overall perimeter of the track system, wherein the track system is movable with regards to the attachment point along the width and/or the length of the vehicle.

2 ) The track system of claim 1 , the track system comprising a pivot module, the pivot module being adapted to be mounted to the support frame, the pivot module comprising a portion adapted to pivotally receive the attachment point.

3 ) The track system of claim 2 , the support frame comprising a receiving surface adapted to receive the pivot module in different positions.

4 ) The track system of claim 3 , wherein the pivot module is movable following a 180 degrees rotation about an axis substantially perpendicular to a plane defined by the receiving surface and/or following a translation with regards to said plane.

5 ) The track system of claim 2 , wherein the attachment point is a protruding portion, a longitudinal axis of the protruding portion being substantially parallel to the width of the vehicle, and wherein the pivotally receiving portion is a hollow portion adapted to receive the protruding portion.

6 ) The track system of claim 5 , wherein the hollow portion and the protruding portion have complementary cylindrical shapes.

7 ) The track system of claim 3 , wherein the pivot module is mounted to the receiving surface of the support frame using fasteners.

8 ) The track system of claim 7 , wherein the pivot module and the receiving surface comprise corresponding fastener receiving locations for attaching the pivot module to the receiving surface.

9 ) The track system of claim 8 , wherein the receiving surface comprises a plurality of fastener receiving locations for attaching the pivot module on the receiving surface at a plurality of locations.

10 ) The track system of claim 1 , wherein at least one of the plurality of wheels is a drive wheel.

11 ) A vehicle comprising a track system as claimed in claim 1 .

12 ) A method for adjusting a position of a track system with regards to the length and/or the width of a vehicle having a pivotal attachment point adapted to receive said track system, the method comprising the step of moving the track system longitudinally and/or transversally in relation to the pivotal attachment point.

13 ) The method for adjusting the position of the track system of claim 12 , the method further comprising the step of moving a pivot module with regards to a support frame of the track system, the pivot module being adapted to be mounted on a receiving surface of the support frame, the pivot module comprising a portion adapted to engage the pivotal attachment point of the vehicle, wherein the movement of the pivot module changes a position of the portion with regards to the support frame.

14 ) The method for adjusting the position of the track system of claim 13 , the method further comprising the steps of:
releasing the pivot module such that the pivot module is able to move with regards to the receiving surface; moving and/or rotating the pivot module with regards to the receiving surface; and attaching the pivot module to the receiving surface.

15 ) The method for adjusting the position of the track system of claim 14 , the method further comprising the steps of:
removing fasteners from holes of the receiving surface and holes of the pivot module; aligning holes of the pivot module with different holes of the receiving surface; and fastening the pivot module to the receiving surface.
