    摘要: A device for automotive vehicles for both traction control and cruise control is equipped with a common servo motor (13) which, by way of a self-locking gear (14), by way of a switchable friction gear (17) and by way of a linkage (23, 24; 25, 26) acts upon a transmission device interposed into the path of force transmission from an accelerator pedal (1) to the throttle-flap (2) of an internal-combustion engine or to the adjusting lever of the injection pump of a spark-ignition engine. Depending on the switch position of the friction gear (17), the servo motor (13) permits control of either the traction (VR) or the speed (GR). During traction control, a release of the accelerator pedal (1) leads at any time to closing of the throttle-flap (2), while an increase of the pedal force does not have any effect on the position of the throttle-flap. After the activation of cruise control, it is still possible to increase the engine power by further depressing the accelerator pedal (1).

    摘要: A brake system with hydraulic force boosting comprises a master cylinder (1) and an auxiliary pressure supply system including a hydraulic pump (10), the driving motor (M) of which is actuated when the brake is applied. The pressure in the working chambers (18,19) of the master cylinder (1) results in the re-switching of valve arrangements (2,3) with the result that the controlled auxiliary pressure is applied to the wheel brakes (4-7) in lieu of the master cylinder pressure (1). For pedal travel simulation, a hydraulic cylinder (37) is connected to a work chamber (19), with the piston (38) of the hydraulic cylinder being displaceable against a restoring spring (39) and against the controlled auxiliary pressure. A pressure-controlled multidirectional valve (40) provides for a connection of the auxiliary pressure source.

    摘要: In a brake slip control apparatus fed by auxiliary energy for use in a vehicular hydraulic brake system, copmrising a master cylinder assembly (12) actuatable by the brake pedal, and with auxiliary energy being supplied into the working chamber (16) of the master cylinder, a positioning tube (39) is arranged axially slidable between stops which causes the master cylinder piston (23) to assume a defined position in the event of application with auxiliary energy. To this end, an undular washer (50) is located between the pedal-side end of the positioning tube (39) and the collar or step (51) of the braking pressure generator (1) isolating the master cylinder assembly (12) from a hydraulic brake power booster (11), with the positioning tube (39) being pressed against the undular washer (50) which pressure-tightly closes an intermediate chamber (54) provided between the master cylinder piston (23) and the booster piston (57) enclosed by the step (51) so that the master cylinder piston (23) is hydraulically locked.

    摘要: A slip-controlled brake system for automotive vehicles comprising two static brake circuits (17, 18) into which a pressure medium is introduceable from a dynamic pressure medium circuit (21, 23) during the control operation, and one dynamic brake circuit (14). Directional control valves (7, 8, 9) are interposed in the brake circuits (14, 17, 18). The directional control valves permit a reduction of the pressure in the wheel brakes and a return flow of the pressure medium to the storage reservoir (3). In addition, two pressure-controlled three-way/two-position valves (40, 40') are interposed in the rear wheel brake circuit (14) between the rear axle regulating valves (6, 9) and the wheel cylinders of the rear wheel brakes (HL, HR). The valves are actuated by the pressure in the front wheel brake circuits (17, 18). The three-way/two-position valves (40, 40') have the effect of reducing the pressure in the diagonal rear wheel break circuit in the event of a failure of one of the front wheel brake circuits due to a defect.

    摘要: A brake system with hydraulic brake force boosting comprises a master cylinder (1), to which the wheel brakes (36 to 39, 36' to 39') are connected, as well as of an auxiliary-pressure supply system (11, 12) and of an auxiliary-pressure control valve (10) which causes an auxiliary pressure proportional to the pedal force (F). Inserted into the pressure fluid conduits from the master cylinder (1) to the wheel brakes (36 and 39, 36' to 39') are pressure-controlled multidirectional valves (15, 15', 16, 16') which, in their initial position, provide for hydraulic communication between the master cylinder (1) and the wheel brakes. After a second switch position has been assumed, the auxiliary-pressure source (11, 12) will be connected to the wheel brakes (36 to 39, 36' to 39'), whereby dynamic braking is effected instead of the master cylinder (1).

    摘要: A hydraulic brake system (FIG. 2) composed of a master cylinder (30) coupled to the brake pedal (46), wherein there is provided a hydraulic booster (31) with a booster piston (91) and a booster chamber (35), and an auxiliary pressure proportional to the pedal force (F) develops in the booster chamber (35) during braking by way of a brake valve (6) actuated by the brake pedal (46). With the booster (31) intact, the auxiliary pressure prevailing in the booster chamber (35) acts by way of a pressure line (85, 87) on the two-stage piston (20) of a fast-fill cylinder (18), whose small stage (95) is immersed into a filling chamber (22) and, during the brake action, presses the pressure fluid available in the filling chamber (22) by way of pressure line (33) into the one brake line (37) connected to the working chamber (34) of the master cylinder (30). When the booster fails, the two-stage piston ( 20) of the fast-fill cylinder (18) remains in its initial position so that the piston (92) of the master cylinder (30) merely brings about pressure build-up in the two brake circuits (36, 37). The piston is moved by the brake pedal (46) by way of the actuating rod (11) and the piston rod (8).

    摘要: A hydraulic brake system for automotive vehicles with a master brake cylinder (1) connected to an unpressurized reservoir and with a brake line (13, 14) connected to a working chamber (4, 5) of the master brake cylinder and leading to pressure control valves of a brake slip control device (40). The pressure control valves are followed by at least one wheel brake (18, 19) with the working chamber (4, 5) of the master brake cylinder (1) being connectable to a pressure medium source (29) upon the start of the brake slip control device. To ensure that in brake systems of different vehicle types, the wheel brakes of which have clearances differing in size, the same master brake cylinder can be used without the master brake cylinder having an undesired long pedal travel and thus a great overall length. This is achieved in that, upon the onset of the application of the brake pedal (3), a pressure medium amount coordinated with the clearance of the brakes can be suppled from the pressure medium source (29) to the brake cylinders of the wheel brakes (18, 19).
