摘要： A retrofit pneumatic circuit complements an existing factory braking system to preserve the original function of the driver's foot pedal while also adding the ability for a computer to actuate the brakes separately and independently. In the event where both the primary and secondary drivers are actuating the brakes at any time, the braking force applied is the maximum of the two. In the preferred approach, a shuttle valve is connected between a primary proportional valve and a copy of that proportional valve. Directional control valves are also included to isolate both the input and the output portions of the secondary circuit in order to enforce positive shutdown of computer control. One directional valve blocks a supply pressure to prevent bleeding of the system in any situation where pressure is requested when computer control is supposed to be disabled. A second directional valve vents any built-up pressure to the atmosphere, so that any residual pressure does not actuate the brakes after computer control is disabled.

摘要： A braking system in a hybrid vehicle is provided. The braking system includes a master cylinder having a first outlet, a second outlet, and a piston disposed therein and translatable from a proximal end to a distal end in response to brake pedal displacement. A brake fluid reservoir supplies hydraulic fluid to the master cylinder. A first fluid circuit connects the first outlet of the master cylinder to the brake fluid reservoir. A second fluid circuit connects the second outlet of the master cylinder to wheel brakes and supplies hydraulic fluid from the master cylinder to the wheel brakes in response to brake pedal displacement. The first outlet of the master cylinder is disposed between the second outlet and the proximal end of the master cylinder such that initial brake pedal displacement transfers brake fluid from the master cylinder to the fluid reservoir to inhibit hydraulic braking during regenerative braking.

摘要： A primary piston composed of a skirt and an intermediate back wall having a rear face receiving the servobrake thrust rod and a forward face for the telescoping rod and the spring pushing the secondary piston. The front of the skirt has longitudinal grooves open in front and closed in the rear. The thickness of the skirt beneath the grooves and the part of the skirt between two successive grooves in the peripheral direction form a front face enabling the principal piston to push the secondary piston. The principal piston is made of a single piece of plastic material.

摘要： A main brake cylinder for a hydraulic vehicle brake system of a motor vehicle is disclosed. The main brake cylinder includes an electric motor that is operated as a generator for decelerating the motor vehicle. For service braking, pressure is applied to a brake circuit by the main brake cylinder and to another brake circuit by a hydraulic pump. In order to reduce a pedal force, a first piston has a smaller piston surface and a second piston only moves if a greater brake fluid volume is required. A preloaded hydraulic accumulator limits an increase in pressure.

摘要： A motor vehicle “brake-by-wire” system having an actuating unit, including a brake master cylinder, actuatable by a brake pedal, has a housing and a piston, arranged displaceably in the housing and, with the housing, delimits a pressure space. The brake master cylinder piston is a stepped piston with two differing size hydraulic active surfaces; a first, small active surface assigned to the pressure space, and a second, large active surface assigned to a filling space. In the “brake-by-wire” operating mode, the filling space is connected to the travel simulator via a pressure medium line such that, in the “brake-by-wire” operating mode, the first small active surface is effective, and, in the recoil plane after a closing travel has been overcome, the second, large hydraulic active surface is effective and the active surfaces are switched over depending on a hydraulic pressure in the pressure space and on the pedal force, respectively.
