摘要： A hydraulic brake booster (12) for use in a brake system (10) having a first housing (100) with a first bore (102) separated from a second bore (104). The first bore (102) retains a power piston (118) and the second bore (104) retains a control valve arrangement (170). A push rod (30) of an input arrangement (49) is connected to the power piston (118) and linked to the control valve arrangement (170) by a lever arrangement (50). A second housing (200) encloses the control valve arrangement (170), lever arrangement (50) and a projection (117) that extends from the power piston (118) to define a cavity or relief chamber (202) having a permanent low pressure. The input arrangement (49) supplies the control valve arrangement (170) with an input force in response to a braking force applied to the push rod (30) to regulate the communication of pressurized supply fluid from the second bore (104). The hydraulic brake booster is characterized in that the regulated supply fluid acts on the first piston (118) to develop a corresponding operational fluid pressure which is communicated to a first set of wheel brakes (14,14′) while the regulated supply fluid is directly communicated to a second set of wheel brakes (18,18′) to effect a brake application.

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 control apparatus for a brake system having a housing with a first bore for retaining a spool valve and a second bore for retaining a selector valve. A cap separates the first bore into a first chamber and a second chamber. The first chamber has an inlet port connected to a source of fluid under pressure, a gear port for connected the source of fluid under pressure to a hydraulically operated device, a relief port connected to a reservoir and an outlet passage connected to a selector valve which communicates pressurized fluid through an outlet port to a brake booster. The second chamber is connected to the reservoir and the second bore. The a spool valve has a peripheral surface with first and second grooves separated by lands and an internal operational passage connecting the second groove to the outlet passage. A first return spring positions the spool valve in the first bore such that pressurized fluid is communicated to the hydraulically operated device by way of the inlet port, first groove and gear port. An actuating apparatus has an input piston that is located in the second chamber for receiving an input force of an operator, a plunger which extends through the cap to be partly located in the first and second chambers, a second return spring for urging the input piston toward a rest position and an actuation spring for connecting the input piston with the plunger. An input force moves the input piston in the second chamber to communicate an actuation force to the spool valve by way of the actuation spring and plunger to position the spool valve and restrict communication between the first groove and the gear port and divert operational pressurized fluid to the outlet passage to effect a brake application. The movement of the input piston within the second chamber is modified by communication of fluid therefrom to the selector valve to provide a smooth rate of actuation for the spool valve and to provide a back up source of operational pressurized fluid in the absence of the source of pressurized fluid.

摘要： A remotely located brake booster for supplying an input force to a pressurizing device to develop pressurized fluid to effect a brake application. The brake booster responds to an actuation signal in the form of pressurized fluid being communicated from a control apparatus activated by an operator. The brake booster has a housing with a bore and a piston located therein to define an operational chamber. The housing has an inlet port through which pressurized fluid from the control apparatus is receiving by the operational chamber. The piston moves from a rest position to an actuation position in response to pressurized fluid being received in the operational chamber to produce the input force for operating the pressurizing device. The brake booster is characterized by an outlet port located in the housing for connecting the operational chamber with a reservoir to allow pressurized fluid to directly flow from the control apparatus to a reservoir by way of the operational chamber to modify the temperature of fluid therein to maintain the viscosity of the fluid at a level sufficient for the piston to return from an actuation position to the rest position within a desired time period and to remove any contamination, including air, that may be present in the operational chamber.

摘要： A secondary source of braking for large hydraulically braked vehicles utilizing the available power source (38) provided by typically available anti-skid and traction control braking systems. The anti-skid braking system is used to control the secondary braking function in a manner optimal to the operating condition of the vehicle. Unique distinctive operating modes are used when the vehicle is either moving (79, 81, 83), or stationary (57, 59, 73). The advantages of the stationary mode are fast time response and high output pressure controlled with a minimum of pump operation and fluid movement. The advantages of the dynamic mode are the ability to modulate brake pressure in response to the driver's command.

摘要： A drum brake for use in a brake system (10) having first (14) and second (16) shoes retained on a backing plate (20). The first brake shoe (14) has a first end (22) connected to an actuator (12) and a second end (26) connected to an anchor arrangement (24) and the second brake shoe (16) has a first end (36) connected to the actuator (12) and a second end (38) connected to the anchor arrangement (24) The actuator (12) responds to an input signal during a brake application by moving the first (14) and second (16) brake shoes into engagement with a drum (18). The anchor arrangement (24) includes a load sensor (64) for measuring a torque generated between the first (14) and second (16) brake shoes and the drum (18). The anchor arrangement (24) has a bracket (44) with a base (46) having first (48) and second (50) side walls which are secured to the backing plate (20). The first side wall (48) has a first central opening (56) therein while the second side wall (50) has a second central opening (58) therein. A core member (64) of the load sensor is retained by the bracket (44) between the first (48) and second (50) side walls is connected to a controller (28). First linkage (66) extends through the first opening (56) for connecting the first brake shoe (14) to the core member (64) while a second linkage (74) extends through the second opening (58) for connecting the second brake shoe (16) to the core member (64). A first linear dimension defined by the core member (64) and first (66) and second (74) linkages is less that a second linear dimension between the first (48) and second (50) side wall such that a gap "x" is created. The first (14) and second (16) brake shoes on engagement with the drum (18) defining a leading brake shoe and a trailing brake shoe. The leading brake shoe produces a first force which moves the core member (64) within the gap "x" to bring one of the first (64) and second (74) linkages into engagement with said bracket (44) and thereafter compress the core member (64) and independently modify an output signal generated therein to define an operational torque developed during a brake application.

摘要： A brake system (10) having a control member (12) through which a remotely located master cylinder (18) is selectively supplied with either a first operational fluid developed by a first pump (14), a second operational fluid developed by a second pump arrangement (500,600) or a third operational fluid from a storage system (302) as a function of a brake force applied to an input push rod (16) and a sensed flow of operational fluid through a shuttle valve (64) to the master cylinder for effecting a desired brake application. A electronic control unit (200) receives an input signal corresponding to the brake force and a sensed flow to activate the second pump arrangement (500,600). Whenever the fluid pressure of the first operational fluid is insufficient, the second pump is activated and the second operational fluid supplants the operation of the master cylinder (18) by the first operational fluid to effect the desired brake application. Whenever both the first fluid pressure in the first operational fluid and the second fluid pressure in the second operational fluid are insufficient, an operator applies additional the input force to the input member (16) and moves an actuation piston (58) past a tilt valve (318) to allow a third fluid pressure in a third fluid retained in the storage system (302) to be communicated to the master cylinder (18) to effect a desired brake application.
