摘要： A hydraulic brake assembly (12) includes a housing (24) having first and second side-by-side bores (30), each defining a respective master cylinder assembly. Each master cylinder assembly includes a master cylinder piston (32) slidably movable by actuation of a respective brake pedal (18a, 18b) to and between an active position and an inactive position. A spool (74) slidably disposed within a piston bore (70) of the master cylinder piston (32) is operable in a first mode to direct hydraulic fluid from a quick-fill chamber (62) to a master cylinder chamber (50) at a first pressure upon initial movement of the master cylinder piston (32) from the inactive position toward the active position. The spool (74) is operable in a second mode to direct hydraulic fluid from the quick-fill chamber (62) to a tank (20) when pressure in the master cylinder chamber (50) reaches a predefined threshold.

A first rod piston element is movable into at least a first partial pressure chamber of the first pressure chamber in such a way that a first partial residual volume of the first partial pressure chamber which is fillable with liquid is reducible by moving the first rod piston element. The master brake cylinder also includes a second partial pressure chamber of the first pressure chamber which is delimited from the first partial pressure chamber via at least one partial partition and into which a second rod piston element is movable in such a way that a second partial residual volume of the second partial pressure chamber which is fillable with liquid is reducible by moving the second rod piston element. Moreover, a manufacturing method is described for a master brake cylinder.

摘要： A brake master cylinder arrangement includes a housing with a cylindrical recess, a pressure piston moveable in the cylindrical recess along a longitudinal axis and guided in a sealing manner, and a reservoir for storing brake fluid that is fluidically connected via a fluid channel to the housing. The pressure piston and the housing enclose a pressure chamber that is connected to a fluid circuit of the brake system. Depending on the position of the associated pressure piston, the pressure chamber is either fluidically connected to the fluid reservoir or disconnected therefrom. In a region that axially spans the sealing arrangement in a starting position of the pressure piston, the outer circumferential surface of the pressure piston has profiling that provides a fluidic connection between the fluid reservoir and the pressure chamber.
