ABSTRACT:
A steering stabilizer is connected between a fixed point on a vehicle frame and a moving point in the steering linkage which connects the vehicle's steerable wheels to the steering gears. The stabilizer includes a single coil spring and two pairs of connecting rods. One of the pairs of rods is secured to the fixed point of the vehicle frame and the other pair is connected to the vehicle steering linkage. The rods have left and right arms positioned adjacent opposite ends of the spring so that the connecting rods can transmit movement of the steering linkage (relative to the fixed point) to the spring to compress the spring when the steering linkage moves both away from as well as towards the fixed point on the frame. The spring is dimensionally sized and the left and right arms are selectively spaced so that the stabilizer is self centering in the absence of external forces acting on the steering linkage. In a first embodiment, the left and right arms of the rods are connected to form a loop encircling circumferential portions of the coil spring, whereas in the second embodiment the left and right arms do not form such a loop in order to facilitate assembly of the stabilizer.
