摘要:
In an underpressure power brake for motor vehicles with a fixed power brake housing (1) and a control housing (8) which is axially movable in relation to the power brake housing (1), there is a sealing ring (14) fitted between the power brake housing (1) and the control housing (8) with a stop (13) for an actuating piston (12), in which the actuating piston (12) is axially movably fitted on the control housing (8) and is designed to actuate a triggering switch (11) to trigger the electromagnetic actuator of the underpressure power brake.

The proposal is for a motor vehicle hydraulic braking system with an actuating unit which is secured to the splashboard of a motor vehicle and actuated by a brake pedal. In order to eliminate the risk of injury especially in a rear end collision, the invention proposes that means (12 - 17, 22, 23, 26, 27) be provided with which, in the event of an accident resulting in deformations of the front of the vehicle, an increased volume requirement for the braking system is simulated, thus producing an increase in the actuating travel of the actuating unit (1, 2).
摘要:
The brake system proposed has a brake line (3) linking the brake-pressure generator (1) with several wheel brakes (2), at least on pressure-control valve (7, 7'), associated with each wheel brake (2), which controls the hydraulic link to the wheel brake (2), a pump (4) which pumps to the wheel brake (2) hydraulic fluid stored in an accummulator (13) connected to a suction line, sensors to measure the wheel rpm and an evaluation circuit (12) for control of wheel slip. The hydraulic-fluid link between the brake-pressure generator (1) and the brakes (2) is provided by the brake line (3) to which the pump (4) is connected, also connected into the line is a monitoring device with a multiple-way valve (5) and a pressure sensor (6) which determines the pressure occurring at the brake pressure-control valve (7).
摘要:
A braking system for electrically driven vehicles consists essentially of a driven front axle (VA) and an undriven rear axle (HA) in the form of a triple-circuit (I, II, III) compound system consisting of hydraulic friction brakes (3, 4, 10, 11) and an electro-regenerative (II) braking system, in which the electro-regenerative braking system makes use of one of the electric drive motors of the motor vehicle for braking and power recovery. The actuation of the friction brakes connected to the second and third braking circuits and the braking force distribution between the front and rear axles are controllable by means of an electronic regulator which receives information via e.g. the brake pedal position and evaluates this information to control the brakes acting on the driven wheels.

The foot-pedal unit (1) described comprises an accelerator pedal (6), a brake pedal (7) and a clutch pedal (8), each of the three pedals (6, 7 and 8) actuating an associated electronally controlled device (potentiometers 9, 10; switch 11) and the pedal unit being pre-assembled and connected by means of electrical terminals to a power supply (2) and a data bus (4). The invention makes available an easy-to-assembly pedal unit which does not require holes in the pedal region of the vehicle bodywork. In addition, the pedal unit (1) satisfies the requirements of the modern manufacturing industry for, for instance, modular design and timely delivery.

摘要:
L'invention concerne un système d'assistance de freinage à dépression pour automobiles, dont la soupape de commande (12) peut être actionnée au moyen d'un électroaimant (20), indépendamment d'une tige de commande (7) qui déplace un piston de soupape (9). L'électroaimant (20) actionne un troisième siège étanche (24) qui permet une ventilation de la chambre de travail (3). Afin de maintenir à un niveau aussi bas que possible la force extérieure d'actionnement exercée par l'électroaimant, l'invention suggère que l'électroaimant (20) soit monté coulissant dans le boîtier de commande (5), tout en étant solidaire du piston de soupape (9), de manière que le troisième siège (24) puisse être déplacé de manière synchrone avec le piston de soupape (9).
摘要:
The invention concerns a brake-actuating device for a motor vehicle parking brake, said device comprising a handbrake lever (1) which acts on two wheel brakes via two brake cables (4, 5). In order to assist manual actuation, the device further comprises an additional electric motor (7) which applies at least some of the actuating force.
摘要:
A vacuum power brake for motor vehicles has a control valve (12) which can be actuated by an electromagnet (20) independently from an actuating rod (7) which pushes a valve piston (9). The electromagnet (20) actuates a third sealing seat (24), allowing the working chamber (3) to be vented. In order to keep the external actuating force to be supplied by the electromagnet (20) as low as possible, the electromagnet (20) is slidingly arranged in the control housing (5) and is fixed to the valve piston (9), so that the third sealing seat (24) is synchronically movable with the valve piston (9).
