Abstract:
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.
