An assembly is provided for limiting the displacement of a track system mounted to the axle of a vehicle. The assembly generally comprises an anchor bracket and a stabilizing rod. The anchor bracket is configured to be fixedly mounted to the chassis of the vehicle whereas the stabilizing rod is pivotally and slidingly mounted, at one end, to the anchor bracket, and generally only pivotally mounted, at the other end, to the track system. While allowing limited rotation, the limiting assembly generally prevents excessive rotation of the track system about the axle.

1. A displacement limiting assembly for use with a track system mounted to an axle of a vehicle, the track system comprising a sprocket wheel coupled to the axle, a frame assembly mounted to the sprocket wheel, wheels mounted to the frame assembly, and a traction band disposed about the sprocket wheel and the wheels, the traction band defining a ground contacting area with a ground surface, the vehicle comprising a frame, at least one suspension arm pivotally connected to the frame and coupled to the axle, the at least one suspension arm being displaceable between an extended position, a normal position and a retracted position, the displacement limiting assembly comprising an anchor bracket configured to be fixedly mounted to the frame of the vehicle, and a stabilizing member comprising a first end pivotally mounted to the anchor bracket at a location distinct from the suspension arm whereby the location does not directly follow the displacements of the suspension arm, and a second end configured to be pivotally mounted to the frame assembly of the track system, whereby the stabilizing member maintains the ground contacting area of the traction band substantially parallel to the ground surface when the suspension arm moves between the extended, normal and retracted positions. 2. A displacement limiting assembly as claimed in claim 1, wherein the anchor bracket comprises an aperture, wherein the first end of the stabilizing member extends through the aperture, and wherein the first end is further slidingly mounted to the anchor bracket. 3. A displacement limiting assembly as claimed in claim 2, wherein the stabilizing member comprises a first resilient element mounted to the first end on a first side of the aperture, and a second resilient element mounted to the first end on a second side of the aperture, whereby the first and second resilient elements limit the sliding movements of the first end of the stabilizing member with respect to the aperture. 4. A displacement limiting assembly as claimed in claim 3, wherein at least one of the first and second resilient elements is an elastomeric bushing. 5. A displacement limiting assembly as claimed in claim 3, wherein at least one of the first and second resilient elements is a spring. 6. A displacement limiting assembly as claimed in claim 1, wherein the axle is the rear axle of the vehicle. 7. A displacement limiting assembly for use with a track system mounted to an axle of a vehicle, the track system comprising a sprocket wheel coupled to the axle, a frame assembly mounted to the sprocket wheel, wheels mounted to the frame assembly, and a traction band disposed about the sprocket wheel and the wheels, the traction band defining a ground contacting area with a ground surface, the vehicle comprising a frame, at least one suspension arm pivotally connected to the frame and coupled to the axle, the at least one suspension arm being displaceable between an extended position, a normal position and a retracted position, the displacement limiting assembly comprising a stabilizing member comprising a first end configured to be pivotally mounted to the frame of the vehicle at a location distinct from the suspension arm whereby the location does not directly follow the displacements of the suspension arm, and a second end configured to be pivotally mounted to the frame assembly of the track system, whereby the stabilizing member maintains the ground contacting area of the traction band substantially parallel to the ground surface when the suspension arm moves between the extended, normal and retracted positions. 8. A displacement limiting assembly as claimed in claim 7, wherein the first end of the stabilizing member is configured to be pivotally mounted to an anchor bracket configured to extend from the frame of the vehicle and being integral with the frame of the vehicle. 9. A displacement limiting assembly as claimed in claim 8, wherein the anchor bracket comprises an aperture, wherein the first end of the stabilizing member extends through the aperture, and wherein the first end is further slidingly mounted to the anchor bracket. 10. A displacement limiting assembly as claimed in claim 9, wherein the stabilizing member comprises a first resilient element mounted to the first end on a first side of the aperture, and a second resilient element mounted to the first end on a second side of the aperture, whereby the first and second resilient elements limit the sliding movements of the first end of the stabilizing member with respect to the aperture. 11. A displacement limiting assembly as claimed in claim 10, wherein at least one of the first and second resilient elements is an elastomeric bushing. 12. A displacement limiting assembly as claimed in claim 10, wherein at least one of the first and second resilient elements is a spring. 13. A displacement limiting assembly as claimed in claim 7, wherein the axle is the rear axle of the vehicle. 14. A vehicle comprising a frame, a rear axle, and at least one suspension arm pivotally connected to the frame and coupled to the rear axle, the at least one suspension arm being displaceable between an extended position, a normal position and a retracted position, the vehicle having mounted thereto a track system comprising a sprocket wheel coupled to the rear axle, a frame assembly mounted to the sprocket wheel, wheels mounted to the frame assembly, and a traction band disposed about the sprocket wheel and the wheels, the traction band defining a ground contacting area with a ground surface, the vehicle comprising a stabilizing member comprising a first end pivotally mounted to the frame of the vehicle at a location distinct from the suspension arm whereby the location does not directly follow the displacements of the suspension arm, and a second end pivotally mounted to the frame assembly of the track system, the stabilizing member maintaining the ground contacting area of the traction band substantially parallel to the ground surface when the suspension arm moves between the extended, normal and retracted positions.
