ABSTRACT:
A stabilizer apparatus which can be connected to the steering mechanism of a vehicle such that movement of the vehicle wheels from a neutral position is resisted by a spring assembly. The apparatus is characterized by a camber plate affixed to the steering arm at the underside of the steering knuckle sleeve and having a fulcrum recess abutting the wheel kingpin. A recovery bar of the same size as the camber plate is held generally parallel thereto by a pair of cables connecting their ends. The recovery bar has a fulcrum pin aligned with the camber plate fulcrum recess and underlying the vehicle axle. The spring assembly has a first coil spring connected in compression between a mounting member and the fulcrum pin and aligned with the king pin and fulcrum pin to urge the recovery bar rectilinearly away from the wheel in a direction parallel to the vehicle axle, and a pair of second coil springs connected in tension between the mounting member and the recovery bar and arranged at equal distances on each side of the first coil spring to urge the recovery bar away from the wheel. Turning movements of the vehicle wheel will move the recovery bar axially toward the wheel, and will be resisted by both the first coil spring and one of the pair of second coil springs.
