Wheel alignment control system for vehicles

A wheel alignment control system for a vehicle having a pair of road wheels opposing each other in the transverse direction of said vehicle, for controlling a wheel alignment factor of said wheels while said vehicle is traveling, comprising:

• vehicle speed detecting means for detecting a vehicle speed of said vehicle;
• control means for receiving a speed data signal from said vehicle speed detecting means representing a current value of said vehicle speed;
• and
• wheel alignment means operatively connected to said control means to receive therefrom a control signal based on said current value of said vehicle speed, for thereby changing and setting said wheel alignment factor in accordance with said current value of said vehicle speed;
• said wheel alignment factor comprises a camber angle of said road wheels;
• said wheel alignment setting means comprises a pair of support members each respectively supporting one of said road wheels, a pair of shock absorbers each having an outer end of a base portion thereof pivotally connected to a corresponding one of said support members, and actuating means connected to said support members for rotatably displacing each of said support members about the base portion of a corresponding shock absorber so as to change said camber angle of said road wheels;
• and
• said control means supplying said actuating means with said control signal for changing and setting said camber angle.

• said wheel alignment factor comprises a static toeing quantity of said rear wheels;
• said wheel alignment setting means comprises a pair of support member each respectively supporting one of said road wheels and each provided with a bracket projecting downwardly therefrom, a pair of radius arms oriented longitudinally of said vehicle body, each radius arm being pivotably attached at a rear end thereof to the bracket of a corresponding one of said support members and at the forward end thereof to a mobile shaft arranged transversely of said vehicle body, and activating means for displacing each of said said mobile shafts horizontally so as to change said toeing quantity between said road wheels;
• and
• said control means supplying said actuating means with said control signal for changing and setting said toeing quantity.
