Abstract
Abstract In a ball-joint type front-wheel suspension system, a disc wheel is supported in a vertically oscillatable manner by a knuckle and a spindle connected to the vehicle body. A brake supporting plate is secured to a flange of the spindle, or to the mounting portion of the knuckle in the case of a front wheel drive. A caliper of a disc brake is formed integrally with the brake supporting plate at one side thereof. A lower mounting seat is formed integrally with the brake supporting plate at the other side thereof. By way of the lower mounting seat and a ball joint or a joint pin, a lower arm is installed so that steering of the wheel is possible.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
In a knee action wheel suspension systems for vehicles, of the type including vertically movable arm means secured at one end to the vehicle, a knuckle having an upper mounting seat means, ball joint means securing the upper mounting seat means to the arm means, a spindle extending from the knuckle, and a flange at the inner portion of the spindle, the improvement comprising a brake actuator carrying member having a planar portion juxtaposed and secured to said flange and having a lower mounting seat formed integrally therewith for securing to said arm means by second ball joint means; said planar portion having a generally U-shaped recess defining an opening on the periphery of said planar portion, whereby said planar portion may be slipped over said spindle to at least partially embrace the same with said Ushaped recess for juxtaposition and securing of said planar portion to said flange.
Claim 2
Dependent Claim
