摘要： A brake system includes a reservoir and a motor-driven master cylinder operable during a backup braking mode by actuation of an electric motor of the master cylinder to generate brake actuating pressure at first and second MC outputs. A power transmission unit provides pressurized hydraulic fluid to a PTU output for actuating first and second pairs of wheel brakes in a normal non-failure braking mode. The power transmission unit includes a side-mounted electric PTU motor configured to selectively pressurize the hydraulic fluid by transmitting rotary motion to a ball nut assembly of the power transmission unit via a force translator mechanically interposed between the electric PTU motor and the ball nut assembly. First and second two-position three-way valves each selectively control hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to a corresponding pair of wheel brakes.

摘要： A brake system control module for use in a brake system is provided. The brake system control module includes a reservoir tank having a brake fluid level sensor. The brake system control module automatically determines if the brake fluid level sensor detects a low fluid level in the reservoir tank and monitors a value of sensors to determine if the value of the sensors is less than or greater than evac and fill start and stop thresholds. The brake system control module further manages an evacuation and a filling of the brake system based on the value of the sensors.

摘要： A parking brake for a wheel rotor having a brake pad associated therewith includes a housing defining first and second passages. First and second pistons are provided in the respective first and second passages. Spindles are threadably connected with each piston. A clutch unit is connected to the spindles. The clutch unit has a first condition allowing relative rotation between the spindles and the pistons such that the pistons are axially movable within the passages and into engagement with the brake pad in response to hydraulic pressure applied to the pistons. The clutch unit has a second condition preventing relative rotation between the spindles and the pistons such that pistons remains engaged with the brake pad when hydraulic fluid pressure is removed from the pistons.

摘要： A testing method includes the steps of: (1) providing a negative pressure generator; (2) generating a negative pressure in a fluid passageway and a chamber which are in fluid communication with a guiding section of a fluid reservoir wherein a second sensing element is affixed to a guiding section of the fluid reservoir; (3) transferring a fluid flow stream from the guiding section to the chamber via the fluid passageway and drawing a float having a first sensing element from an upper position to a lower position within the guiding section; (4) generating a signal via the first and second sensing elements as the float moves relative to the second sensing element within the guiding section; and (5) transmitting a signal to at least one of a control unit or a graphical user display.

摘要： A brake system for selectively actuating at least one of a pair of front wheel brakes and a pair of rear wheel brakes includes a reservoir and a master cylinder. A power transmission unit is configured for selectively providing pressurized hydraulic fluid. A pair of rear brake motors selectively electrically actuate rear parking brakes. An electronic control unit controls at least one of the power transmission unit and the pair of rear brake motors. A normally-closed DAP valve is located hydraulically between the power transmission unit and at least one of a two-position three-way valve and at least the selected one of the pairs of wheel brakes. An isolation valve and a dump valve are associated with each wheel brake.

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： A brake system for selectively actuating at least one of a pair of front wheel brakes and a pair of rear wheel brakes of a vehicle, one of which is hydraulically actuated and the other of which is electrically actuated, includes a reservoir. First and second integrated control units are in fluid communication with the reservoir and respective ones of the hydraulically actuated wheel brakes. The first and second integrated control units have first and second power transmission units connected to first and second electronic control unit, respectively. Each electronic control unit is configured to control a corresponding power transmission unit and a selected one of the electrically actuated wheel brakes on a contralateral side of the vehicle from the selected one of the hydraulically actuated wheel brakes which is actuated by the power transmission unit.

摘要： A brake system with a wheel brake has a fluid reservoir and a valve assembly in fluid communication with the reservoir via a first conduit. The valve assembly is in fluid communication with the wheel brake via a second conduit. The valve assembly includes a bypass valve which only permits fluid flow from the first conduit to the second conduit when the fluid pressure within the first conduit is above a predetermined pressure level above atmospheric pressure. The valve assembly further includes a check valve in a parallel path arrangement relative to the bypass valve such that the check valve permits fluid flow from the second conduit to the first conduit, and prevents fluid flow from the first conduit to the second conduit. The brake system further includes a first source of pressurized fluid providing fluid pressure for actuating the wheel brake, wherein the first source of pressurized fluid is selectively in fluid communication with the second conduit.
