摘要： An electrically actuated hydraulic power cylinder (10, 100, 200) for use in a vehicle braking system. The power cylinder includes an electric motor (12, 102, 202), a rotary-to-linear actuator for converting rotary motion of the electric motor to a linear motion, and a hydraulic cylinder. In a preferred embodiment, the rotary-to-linear actuator is a roller screw assembly (14, 104, 204). The roller screw assembly converts rotational motion generated by the motor into axial movement of a piston which is disposed within the hydraulic cylinder. The movement of the piston pressurizes a volume of fluid. The pressurized fluid flows through an outlet port (20) connected to either a single wheel brake cylinder (21) or a plurality of wheel brake cylinders, thereby actuating the associated wheel cylinder. In a specific embodiment of the invention, the roller screw assembly is incorporated into the internal structure of the motor for compactness and weight reduction. Also, the hydraulic cylinder may be integrated into a wheel brake assembly for compactness and weight reduction.

摘要： An improved structure for an electro-mechanical disc brake caliper assembly. The electro-mechanical disc brake caliper assembly includes an electro-mechanical actuation mechanism, a piston unit, and a freewheeling clutch. The electro-mechanical actuation mechanism includes an electrical actuating unit, an eccentric actuating lever, a mechanically actuated piston unit, and an automatic adjustment mechanism. The electrical actuating unit includes an electric motor and a motor spindle operatively coupled to the motor so as to convert rotary motion of the motor into axial movement of the motor spindle. The motor spindle operatively engages the lever so as to cause the lever to pivot relative to a lever pivot axis. The piston unit is operatively coupled to the lever and includes a piston spindle and a piston. The piston spindle is operatively coupled to the lever so as to be axially moved during actuation of the lever. The piston spindle is operatively coupled to the automatic adjustment mechanism so as to cause adjustment of the piston spindle during actuation of the electro-mechanical actuation mechanism if the piston moves more than a predetermined brake clearance distance. The freewheeling clutch is adapted to limit the adjustment provided by the automatic adjustment mechanism.

摘要： An electrical actuation mechanism (40) adapted for use in a disc brake assembly (10) includes an electrical actuation mechanism (40) adapted to be secured to an inboard leg (12) of the caliper (11) of the disc brake assembly (10). The electrical actuation mechanism (40) includes a housing (41) and electrical motor (42) disposed in the housing (41) and a spindle (43) disposed in the housing (41) and operatively coupled to the motor (42) by a conversion gear assembly (48, 44, 43) which is effective to convert rotary motion generated by the motor (42) into axial movement. A dampening structure (53) can be comprised of elastomeric material (52) or a fluid filled chamber (85) defined between the piston (71) and the shaft (72). The dampening structure (63) reduces the radial loads acted upon the piston (71) from being transmitted to the shaft (72). The electrical actuation mechanism (40) may also be equipped with sensor (99) for sensing the axial position of the piston (71), a clutch, to couple and uncouple the electric motor (42) from the conversion gear assembly (48, 44, 43) and a mechanism (100) which prevents back drive motion of the electrical motor (42).

摘要： An antilock/traction control/vehicle stability braking system hydraulic circuit using a fluid flow intensifier (98) to provide a rapid application of fluid pressure to brakes during a TC/vehicle stability control operation at a flow rate that is greater than is normally available from an ABS pump (60) alone. The intensifier (98) increases the fluid flow as a function of using a stepped piston (105) operating within respective input (99) and output (103) chambers having different effective diameters. The intensifier (98) also includes an intermediate chamber (101) into which fluid dumped from a brake cylinder is drawn rather than being lost to a master cylinder reservoir (12). The fluid thus remains in the hydraulic circuit, ensuring that a desired ratio of pedal travel versus pressure is maintained after a transition from TC/vehicle stability braking to ABS-base braking.

摘要： The method and system for controllably restricting the on time of a pump (32) of an electro-hydraulic control system for a hydraulic brake system by modelling the amount of hydraulic brake fluid in a low pressure accumulator (LPA) of the hydraulic brake system. Sensors (24) sense wheel speed of their respective wheels (20) of a vehicle. Control valves (34, 36), including isolation and dump valves, together with the pump (32), vary the amount of brake fluid in the LPA. A control unit (26) electrically coupled to the pump (32), the control valves (34, 36) and the wheel speed sensors (24), initially detects an electro-hydraulic control event based on the sensed wheel speeds and then activates the control valves (34, 36) and pump (32) which vary the amount of brake fluid in the LPA. The control unit (26) models the amount of brake fluid in the LPA during the activation and controls the state of the pump (32) based on the modelled amount of brake fluid in the LPA. The modelled amount of brake fluid in the LPA consequently is based on the on time of the pump (32) and the total on time of all of the dump valves (34, 36) in the electro-hydraulic control system.

摘要： Method and system for testing components, such as a motor, of a vehicular system capable of controlling the relative slip between a vehicle wheel and a road surface, for functionality prior to performing antilock functions utilizing a progressively increasing energization duty cycle, so as to minimize perception of noise by the vehicle operator by minimizing motor energization duration and minimizing peak motor rotational speed. The method includes energizing the motor successively with a plurality of electrical signals, each electrical signal being applied to the motor for a predetermined period of time and having at least one pulse having a width which is progressively increased with respect to the width of the at least one pulse of the previous electrical signal. Each pulse has a width sufficiently long to permit motor operation to test functionality and yet sufficiently short so that the noise associated with the operating motor during this test is minimized.

摘要： A vehicle brake system (10, 350, 400, 430, 460, 500, 530, 560, 600, 750, 800, 820) having a pilot-operated brake valve (70, 130, 424, 474, 514, 532, 580, 614, 660, 775). The brake system has a wheel brake (22, 23, 358, 360, 362, 364, 566, 568, 572, 574, 602, 604, 606, 608, 752, 754, 756, 758, 802, 804, 806, 808, 822, 826, 828) and a master cylinder (12) operatively connected to the wheel brake via first fluid conduit (16, 416, 417, 516, 518, 534, 536). The brake system further includes a pedal simulator (100, 562, 564, 652) for storage of pressurized fluid and an isolation valve (26, 28, 366, 368, 418, 419, 444, 576, 578, 628, 634, 850). The isolation valve is moveable between a first position, wherein fluid is permitted to flow from the master cylinder to the wheel brake via the first fluid conduit, and a second position, wherein fluid is prevented from flowing from the master cylinder to the wheel brake via the first fluid conduit. A source of pressurized fluid (61, 612, 782) is in fluid communication with the wheel brake via a second fluid conduit (20, 538, 582, 618, 784). The pilot-oprated boost valve (70, 130, 424, 474, 514, 532, 580, 614, 660, 775) regulates the flow of fluid through the second fluid conduit from the source of pressurized fluid to the wheel brake.

摘要： A vehicular brake system (10, 110) having vehicle stability management (VSM) includes a hydraulic master cylinder (12, 112) connected to wheel brakes (30, 31, 128-131) via brake conduits (26, 124, 126). A pump (54) generates fluid pressures and pressure control valves (44, 46, 56, 58) located between the master cylinder (12, 112) and the wheel brakes (30, 31, 128-131) regulate the fluid pressures at the wheel brakes (30, 31, 128-131) to achieve ABS and traction control. A medium pressure accumulator (66) stores fluid pressurized by the pump (54) which is supplied to the wheel brakes (30, 31, 128-131) via associated control valves (70, 72) to achieve VSM braking control. The brake system has low power requirements because the medium pressure accumulator (66) does not have to be filled quickly, yet the stored pressurized fluid can be released to the wheel brakes (30, 31, 128-131) to quickly produce the braking pressures necessary for initiating most VSM applications. The pump (54) is used to supplement the accumulator pressures to achieve full VSM control.
