    Abstract: A fluid cooled drum brake system (10) comprises a drum (12) having an inner circumferential surface (14) to which is attached a layer of friction material. Two sets of brake shoes (18a, 18b) are rotationally fixed within the drum (12). Each shoe (18a, 18b) has an outer surface which forms a braking surface (20) facing the friction material, a fluid inlet, a fluid outlet, and a number of fluid flow paths in fluid communication between the fluid inlet and the fluid outlet, and extending beneath the braking surface (20). A pair of double acting hydraulic piston (28) applies force to the brake shoes (18a, 18b) to urge their respective braking surfaces (20) against the friction material. A cooling fluid circulates through the fluid flow paths to extract heat from the shoes (18a, 18b) and the braking system (10).

    Abstract: A hydraulic brake system (10) for operating service brakes (12, 14) and (16) is provided with first and second master cylinders (20, 22) which feed into input ports (26) and (28) of a valve (24). Dupli cate hydraulic circuits (30) and (34) are coupled with respective output ports (32) and (36) of the valve (24). Each of the hydraulic circuits (30) and (34) also includes a common circuit po rtion comprising a selective valve (44) and common line (42) leading to brake (16). The system (10) also includes hand brake (18) which is electrically deployed and manually released. A controller (52) controls operation of the system (10) to switch between master cylinders (20) and (22), and hydraulic circuits (30) and (34), depending on sensed fluid pressure. In the event of switching both master cylinders (20) and (22) to one of the hydraulic circuits (30) or (34), and a controller continuing to sense low fluid pressure, the common circuit is isolated. In the event of a sensed complete hydraulic failure, the controller (52) automatically deploys the park brake (18).

When the hydraulic pistons (16) are operated to push the brake shoes (14) into contact with the drum (12) to provide a service brake effect, the park brake (36) can be deployed whereby the pins (38) engage the brake shoes (14) to hold them against the drum (12) after release of the pistons (16), to provide a park brake. The pins (38) are selectively engaged with and disengaged from the shoes by action of corresponding solenoids (40).

    Abstract: A brake actuator includes an annular housing (10b) having first and second opposite radial faces (A and B). Cavities are formed in the housing (10b), some opening onto face (A) and some onto radial face (B). Two pistons (16) are disposed in each of the cavities and are movable under the influence of fluid pressure exerted from within the respective cavities to a braking position where the pistons (16) extend axially away from the cavity. The piston (16) bear against a backing plate of respective brake pads (68) forcing the brake pads (68) against brake discs (54 and 56). By providing cavities on both faces (A and B) of the housing (10b), an actuator can simultaneously apply brake pads to two spaced apart rotating discs (54 and 56). A plurality of actuators can be coupled together to act on a plurality of axially spaced apart brake discs to form a multi-pad multi-brake system.

    Abstract: A park brake (14) is incorporated into a housing (10) of a disc brake system (12). The housing (10) is in the form of an annular ring having a plurality of cavities (16) for housing service brake pistons which act on brake pads (18) to selectively force the brake pads (18) onto a brake disc to produce a surface brake effect. The park brake (14) includes an actuator (23) supported by the housing (10) which is switchable between an applied state where it forces the brake pad (18) into contact with the brake disc of the system (10) independent of the action of the service brake pistons to produce a park brake effect, and a released state where the actuator (23) allows the brake pad (18) to become disengaged from the brake disc. The actuator (23) includes a hydraulically operated park brake piston (27) having a rod (24) extending therefrom. The rod (24) is slidably retained within a hole (26) formed in the housing (10) and is arranged to abut or otherwise apply force to the brake pad (18). When fluid pressure is applied to the pad brake piston (27) it retracts the rod (27) into the housing (10) releasing the park brake (14). In the absences of the application of fluid pressure, a spring (34) of the actuator (23) operates to switch the actuator (23) to an applied state where the rod (24) pushes on the pad (18) forcing it into contact with the brake disc thereby providing the park brake effect.
