Abstract

The invention relates to a camber control suspension of a vehicle that can form a stable camber angle even at the time when the vehicle rolls as well as when bumping and rebounding, including a camber control rack and camber control links which function to control camber of wheels by stopping or moving according to the vertical motion of both wheels. As a result, a most stable ground contact state of the tires at all times is achieved to sufficiently enhance the groiund contact force of the tires at any running state of the vehicle.

Claims

1. A camber control suspension comprising:

two roll detecting links respectively connected to a front part of a wheel rotational center at a knuckle of a left wheel and to a rear part of a wheel rotational center at a knuckle of a right wheel which form a L shape and are bent at a position where the links cross with a vertical line passing through the wheel rotational center of the wheels;

a rotary support bracket contacting a vehicle body and which guides rotations of two roll detecting links;

a differential gear unit including two side gears respectively installed at each end of the two roll detecting links;

a worm gear located on an exterior of a gear case of the differential gear unit;

a camber control rack formed with a gear meshing with the worm gear and horizontally installed with a vehicle axle to provide a horizontal linear motion;

camber control links connecting respective sides of the camber control rack to the wheel knuckles; and

lower links supporting a lower side of the wheel rotational centers of the knuckles against a frame of the vehicle.

2. The suspension, as defined in claim 1, wherein the two roll detecting links are connected to the knuckles through ball joint links which comprise one end ball joint vertically connected to the roll detecting links and another end ball joint connected to the knuckles.

3. The suspension, as defined in claim 1, wherein the camber control rack is installed over a case of the differential gear and the camber control links are connected to transmit the linear motion of the camber control rack to an upper side of the wheel rotational center of both wheel knuckles.
