Abstract
A vehicle braking system in which an annular piston brake and a booster to generate an amplified output force for actuating the brake are combined to form an integrated unit. The booster is mounted on an axle casing in which the piston brake is located so that the amplified force acts directly on fluid in a chamber to displace the piston brake. A self-bleeding facility for the brake fluid is provided via the booster.
Claims18
A vehicle braking system comprising:
- a brake for a wheel of a vehicle;
- and
- a booster to boost an input force and generate an amplified output force to actuate said brake, said booster and said brake combined in an integrated unit wherein said booster has a boost piston working in a bore to generate said amplified output force in response to a pressure applied to a power chamber under control of a valve, in turn, responsive to said input force;
- and
- wherein said valve controls communication between said power chamber and either one of a reservoir tank and a pressurized fluid supply in response to said input force.

A vehicle baking system comprising:
- a brake for a wheel of a vehicle;
- and
- a booster to boost an input force and generate an amplified output force to actuate said brake, said booster and said brake combined in an integrated unit wherein said brake includes a piston slidable in a bore to apply a braking force under a control of a fluid pressure in a chamber responsive to said amplified output force of said booster;
- and
- wherein said chamber is self-bleeding when said brake is inoperative.
