Apparatus for adjusting toe angle of wheel

In a suspension having two arms extending laterally of a car body and spaced mutually in front and to the rear of each other in the direction of the length of the car body, and a carrier rotatably connected about a vertical axis to outer ends of said two arms to support a wheel, an apparatus for adjusting a toe angle of said wheel, comprising:

• a toe adjuster connected to an inner end of one of said two arms and mounted on the car body, said adjuster including means for displacing said inner end in one plane to change a toe;
• and
• an electric motor for operating said toe adjuster, wherein said means for displacing comprises a worm wheel meshing with a worm fixed on a rotary shaft of said motor, a shaft coupled with said worm wheel and fixed to a pair of circular collars at a position eccentric to centers of said collars, wherein said collars are spaced apart from each other along the axis of said shaft, a pillow rotatable integrally with said shaft and having a convex spherical surface on an outer periphery and an outer tube fitted onto the pillow having an inner periphery including a concave spherical surface and a pair of tapered surfaces diverging from the concave spherical surface, whereby said outer tube may move relative to said pillow with at least two degrees of freedom, and wherein said one of the arms is secured fixedly to said outer tube.

In a suspension having on each side of a car body two arms extending laterally of the car body and spaced mutually in front and to the rear of each other in the direction of the length of the car body, and a carrier rotatably connected about a vertical axis to outer ends of said two arms of each side of the car body to support a wheel, an apparatus for adjusting toe angles of the wheels disposed on both sides of the car body, comprising:

• a pair of two adjusters, each of which is connected to an inner end of one of said two arms of each side of the car body and mounted on the car body, each adjuster including means for displacing said inner end in a horizontal plane two dimensionally to change a toe;
• and
• at least one actuator means for operating said toe adjusters.
