ABSTRACT:
A vehicle supplementary spring assembly is adapted to supplement the spring force provided by a leaf spring of the vehicle. The spring assembly includes an elongate coil spring which forms an axially extending passage having a wall of helical configuration defined by the inner surface of the coils of the coil spring. A first anchoring insert 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. A first connector member is connected to the anchoring insert and is adapted to connect the supplementary spring assembly to a first reaction point on the vehicle. A second connector member is connected to the other end of the coil spring and is adapted to connect the supplementary spring assembly to a second reaction point on a 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, said supplementary spring assembly being 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.
