<p>A vehicle supplementary spring assembly (10) is adapted to supplement the spring force provided by a leaf spring of the vehicle. The spring assembly includes an elongate coil spring (12) which forms an axially extending passage having a wall of helical configuration defined by the inner surface of the coils of the coil spring (12). A first anchoring insert (13) is configured to be in threaded engagement with the wall of the passage and is adapted to be screwed into one end of the coil spring (12). A first connector member (18) is connected to the anchoring insert (13) and is adapted to connect the supplementary spring assembly (10) to a first reaction point on the vehicle. A second connector member (34,37) is connected to the other end of the coil spring (12) and is adapted to connect the supplementary spring assembly (10) to a second reaction point on the vehicle. The first and second reaction points are selected in use such that a tensile force applied between the reaction points will supplement the action of the leaf spring in supporting the vehicle. The supplementary spring assembly is adapted to apply a tensile force between said first and second reaction points, said tensile force being selectively variable by varying the position of the anchoring insert along the length of the passage. <IMAGE></p> |
