摘要： A control apparatus (12) for a brake system (10) having a housing (40) with a first (42) and second (46) cylindrical members located in first (44) and second (46) bores. The first (42) and second (46) cylindrical members and corresponding first (50) and second (54) valve seat members define first (52) and second (56) chambers within the first (44) and second (46) bores which are connected to a source of pressurized fluid. First valve means (68) are located in the first chamber (52) and second valve means (70) are located in the second chamber (56). A first plunger means (72) in the first bore (40) and a first valve seat member (50) define a first brake chamber (74) which is connected to a first set (16) of wheel brakes and a second plunger means (76) in the second bore (48) and a second valve seat member (54) define a second brake chamber (78) in the second bore (46) which is connected to a second set (16′) of wheel brakes in the vehicle. A first stem (82) of the first plunger means (72) and a second stem (88) of the second plunger means (76) is connected to a balance lever (100) connected to an input rod (18). An input force applied to the input rod (18) simultaneously moves the stems (82,88) to initially interrupt communication between chambers (74,78) and a reservoir 84. Thereafter, further movement of stems (82,88) moves balls (67,67′) away from valve seat members (50,54) and allows metered pressurized fluid to be communicated to the first (16) and second (16′) set of wheel brakes to effect a primary brake application. In response to dynamic conditions sensed by a cpu (17), solenoid valves (21,25) are activated to allow pressurized fluid to move the first (50) and second (54) valve seat members into corresponding engagement with first (72) and second (76) plunger means initially interrupt communication between chambers (74,78) and reservoir (84). Thereafter, further movement of the first (50) and second (54) valve seat members allows metered pressurized fluid to be communicated to the first (16) and second (16′) set of wheel brakes to effect a secondary brake application and attenuate a dynamic condition experienced by the vehicle.

摘要： A hydraulic brake booster has a housing with a stepped bore for retaining a cylindrical piston and a control bore for retaining a control valve. The cylindrical piston defines, with the stepped bore, an output chamber, a relief chamber and a power chamber; and includes a second stepped bore for a reaction piston. The reaction piston includes an axial bore, receiving a plunger defining an actuation chamber and a poppet valve. The input force initially moves the plunger and poppet valve to interrupt communication between the actuation and relief chambers; and thereafter moves the plunger to pressurize fluid in the actuation chamber, creating an input signal. The input signal activates the control valve; generating a regulated pressurized fluid, supplied directly to a second set of wheel brakes and acts on the cylindrical piston, to pressurize operational fluid supplied to a first set of wheel brakes.

摘要： A hydraulic brake booster (12) having a housing (100,200) with a first bore (102) separated from a second bore (104). The first bore (102) retains a power piston (50) and the second bore (104) retains a control valve (60). The first bore (102) is connected by a passage (112) to the second bore (104) that is connected to a source of pressurized supply fluid (24). In responsive to a desired braking force being applied to the input member (30,30′), the lever arrangement (80) moves the control valve (60) to allow controlled pressurized supply fluid to be communicated from the second bore (104) by way of passage (12) to the first bore (102). The hydraulic brake booster (12) is characterized by adjustable regulator means (300) connected to the first bore (102) for communicating a proportional reaction signal to the input member (30, 30′) that is derived from the controlled pressurized supply fluid to produce a variable gain between the input force applied to the input member (30, 30′) by the operator and the operational force developed through the power piston (50) to effect a brake application.

摘要： A brake booster wherein second and third pistons are separated within a bore of a master cylinder to define second and third chambers. Compensation valves control the flow fluid from a reservoir to the bore while a passage in the second piston connects the second chamber with the third chamber that is connected to the reservoir through an tilt valve that is held opened by pressurized fluid acting on a fourth piston. A control valve responds to a resiliently applied force from an input rod carried by the third piston to supply pressurized fluid to the brake system. In an event pressurized fluid is unavailable, a spring moves the fourth piston and a sixth spring to moves the tilt valve against a seat to seal the third chamber and create a hydraulic lock. Further movement of the third piston correspondingly moves the second piston to effect a manual brake application.

摘要： A brake system (10) having a brake booster (12) that is responsive to an operator brake input for providing a first input force to a master cylinder (13) to develop a first brake application and is responsive to a hydraulic input for providing a second input force to a master cylinder (13) to develop a second brake application. An electronic control unit (ECU) (40) receives first input signals from sensors (19) indicative of a speed for each wheel (14,14′,18,18′) in a brake system of the vehicle. The ECU (40) supplies a pump (42) with an operational input signal when a sensed wheel speed indicates a wheel lock may occur between a wheel and a surface during a brake application and simultaneous activates a decay valve (17) to release pressurized fluid from actuation of the wheel brake associated with the wheel. When the sensed condition is obviated, the ECU (40) supplies a signal to close the decay valve (17) and open a build valve (15) to provide secondary pressurized fluid from a pump (42) to the wheel brake to resume and complete the first brake application. The ECU (40) also receives an input from a pressure sensor (52) associated to with an accumulator (22) and when the fluid pressure in the accumulator (22) is below a preset pressure, the ECU (40) supplies the pump (42) with an actuation signal through which pressurized fluid is developed and communicated to maintain the fluid pressure in the accumulator (22) above the preset pressure. The ECU (40) supplies valves (56,58,34) associated with the accumulator (22) with an input signal to deliver pressurized fluid from the accumulator (22) as the hydraulic input to effect the second brake application.

摘要： A master cylinder (12,212) including a housing (40,40a) with a bore (42,42a) for retaining a piston assembly (100,200) to define a first chamber (54) that is connected to wheel brakes (14,14′) in a first brake circuit and a second chamber (56) that is connected to wheel brakes (18,18′) in a second brake circuit. The piston assembly (100,200) includes a sleeve (102,202) and a concentric cylindrical body (110,210) whose respective first and second end surface areas define a first effective area (D1) while the second end surface area of the cylindrical body (110,210) defines a second effective area (D2) within the bore (42,42a). A valve (60) activated by axial movement of an input member (30) allows operational hydraulic fluid to be simultaneously communicated to the wheel brakes (14,14′) and the first chamber (54) where the operational hydraulic fluid acts on the first effective area (D1) to move the piston assembly (100,200) and pressurize fluid in the second chamber (56) to develop pressurized fluid that is communicated to wheel brakes (18,18′) to complete a first brake application. In an absence of operational hydraulic fluid in the first chamber (54), a manual input acts on the cylindrical (body 110,210) to move the second effective area (D2) into the second chamber (56) and pressurize fluid therein to initiate a second brake application.

摘要： A back-up power assisted braking system substitutes an intermittently actuated secondary source of pressurized hydraulic fluid such as a traction control/anti-lock pump and motor (41) for the normal braking power assist upon the detection of a failure in the primary power assisted braking system. A failure may be detected in responsive to sensing simultaneous brake pedal (23) displacement and a lack of fluid flow for providing an abnormality signal. Also, a failure may be detected by sensing a predetermined difference between the commanded braking force (45) and the actual braking forces (38, 49). There is a pressure transducer (45) which provides an indication of brake pedal commanded braking force and a hydraulic circuit (43, 53 or 55, 51) interconnecting the secondary source outlet, the individual wheel brake actuators (14) and secondary source inlet. A normally open solenoid operated valve (31, 47) is interposed in the hydraulic circuit between the wheel brake actuators and the secondary source inlet, and a control arrangement is coupled to the pressure transducer to provide an output voltage for enabling the solenoid of the solenoid operated hydraulic valve having a magnitude which varies directly as the indicated operator commanded braking force. Thus, the voltage level determines the braking force during back-up braking.
