摘要： A non-return valve for a vehicle hydraulic-power brake system. The non-return valve has a valve-seat part in the form of an apertured disk, onto which is pressed a valve cage in which a valve ball is disposed as shut-off member and a helical compression spring is disposed as valve spring. A bowl-shaped filter is secured in a depression in the valve-seat part opposite the valve cage.

摘要： A brake system includes a single chamber power transmission unit, a plurality of wheel brakes, and an iso/dump control valve arrangement associated with each wheel brake of the plurality of wheel brakes. A reservoir is hydraulically connected to the single chamber power transmission unit and to each of the iso/dump control valve arrangements. A pump piston is associated with at least one wheel brake. The pump piston is driven by a second electric motor for selectively providing pressurized hydraulic fluid from the reservoir to the iso/dump control valve arrangement of the at least one associated wheel brake. First and second switching valves are provided, and are two-position, three-way type valves, each hydraulically interposed between at least one iso/dump control valve arrangement and both of a selected pump piston and the output line of the single chamber power transmission unit. First and second electronic control units are provided.

摘要： An axle valve module of a compressed air brake system includes a relay valve with a control pressure input connected to a control pressure line which can be connected via a changeover valve alternately to a brake pressure line conducting an introduced brake pressure or to a reservoir pressure line conducting a reservoir pressure. ABS inlet and outlet valves are each formed as a pressure-controlled diaphragm valve with assigned pilot valve, wherein the pilot valves are configured as cyclically controllable 3/2-way magnetic switching valves, A shut-off valve is arranged in the control pressure line of the relay valve, between the changeover valve and the control pressure input of the relay valve or the branch point of a control pressure line of the ABS valves, via which shut-off valve the control pressure present at the control pressure input of the relay valve can be locked in as required.

摘要： A drive control apparatus is applied to a drive system that is mounted to a vehicle, drives wheels of the vehicle by a motor, and brakes the wheels by a brake apparatus. The drive control apparatus determines a road-surface state of a travel road of the vehicle. The drive control apparatus suppresses slipping of the vehicle by correcting a drive torque by correcting at least either of a motor torque and a brake torque. When determined that the drive torque is to be corrected, the drive control apparatus adjusts a correction amount of the drive torque by adjusting the motor torque with higher priority than the brake torque in response to be determined that the road-surface state is rough.

摘要： A power-operated hydraulic brake system for a wheeled vehicle includes a main brake line; a brake valve configured to input a target brake pressure into the main brake line, the brake vale configured to be actuated via a brake pedal; a plurality of wheel brake lines branching off from the brake valve, each of which leads to an actuating unit of a wheel brake; and a valve assembly of an ABS control system. The valve assembly includes an inlet valve arranged between the main brake line and one of the wheel brake lines, and an outlet valve arranged between the relevant wheel brake line and an unpressurized return line. The inlet valve and the outlet valve are pressure-controlled 2/2-way switching valves with correspondingly large switching cross sections, and the inlet valve and the outlet valve are each assigned at least one pilot valve designed as a solenoid switching valve.

摘要： A method for operating a motor vehicle brake installation. An electrically controllable pressure modulation device having a pump-valve arrangement is hydraulically arranged between the primary brake system and the front axle brakes. The pump-valve arrangement includes, for each front brake, a first valve, arranged between the inlet valve of the primary brake system and the brake, and an electrically activatable pump, with a suction and pressures ports. The pressure port is connected to the brake. In the presence of a predetermined condition of the primary brake system and of an actuation of the master brake cylinder by the driver, a build-up of brake pressure at the front axle brakes is performed by the pump-valve arrangement. The pressure set by the pump-valve arrangement is higher than the brake pressure in the master brake cylinder, whereas the brake pressure of the master brake cylinder prevails at the brakes of the rear axle.

摘要： An electromechanical actuator for use in a hydraulic braking circuit of a vehicle comprises an electric motor having a stator and a rotor, and a linear actuator that is located within the motor. The linear actuator comprises an elongate shaft having a screw part at one end carrying an external thread that extends along a portion of the shaft, and a fixing part at the other end shaft, the linear actuator further comprising a drive nut that surrounds the screw part of the shaft and is located at least in a retracted position inside an enlarged bore of the first portion of the rotor body, the drive nut being connected to the screw part through a set of balls that engage the threads of the drive nut and screw part, and the fixing part of the shaft includes a tapering portion that engages a complimentary tapering portion of the bore in the second portion of the rotor body.

摘要： A plug-type driver assistance device includes an external brake module and an auxiliary control module. The external brake module includes a hydraulic pump and a control valve group, the control valve group includes an inlet valve and an outlet valve, and the hydraulic pump is connected between the inlet valve and the outlet valve. The auxiliary control module includes a receiving unit, a processing unit and an output unit. The processing unit selectively switches to the original vehicle control mode or the assist driving mode. The original vehicle control mode means that the processing unit receives the accelerator pedal signal and controls the output unit to output the accelerator pedal signal. The assist driving mode means that the processing unit receives the surrounding information of the vehicle, and generates an analog pedal signal and an analog braking signal.
