Definitions

  • Hydraulic brake system with high pressure source and pedal operated metering valve
  • the present invention relates to a hydraulic dual-circuit brake system according to the preamble of claim 1.
  • brake systems are already used for vehicles which have a front axle-rear axle brake circuit division and, for the purpose of traction control, have a pressure line from the high-pressure source to the brake circuit of the driven wheels.
  • Brake systems of this type have the advantage that only one high-pressure source is required for pedal-operated normal braking, for brake slip control and for traction control, which can also optionally provide pressure medium for level control of the vehicle.
  • Active braking i.e. brake pressure build-up independent of the brake pedal, is required under certain conditions in both brake circuits. For example, traction control with diagonal brake circuit division requires the possibility of active braking of both wheel brakes on the driven axle.
  • the object of the present invention is to upgrade a brake system of the type mentioned at the outset as cheaply as possible for active braking in both brake circuits.
  • the principle of the present invention is to dispense with a further pressure source, but to ensure brake circuit separation even during active braking by means of suitable valve arrangements.
  • a suitable valve arrangement has a check valve in each pressure branch, which leads from the pressure line to the individual brake lines, which prevents the pressure medium from flowing back from the brake circuits into the pressure line.
  • the pressure line itself can then be blocked by a switching valve, so that the pressure medium connection from the high pressure source past the metering valve to the brake circuits is prevented as long as active braking is not required.
  • Another suitable valve arrangement provides a switching valve in each of the two pressure branches. Although this solution is somewhat more expensive than the former, it has the advantage that active braking can also be carried out selectively in one of the two brake circuits without influencing the other brake circuit.
  • FIG. 1 shows the hydraulic circuit diagram of a brake system according to the invention
  • Fig. 2 shows a section of an inventive
  • Fig. 1 shows a hydraulic circuit of a brake system with diagonal brake circuit division, which is suitable for traction control.
  • the brake system has a storage container 1, to which the suction side a high-pressure pump 2 is connected.
  • This high-pressure pump 2 loads a high-pressure accumulator 4 via a pressure-limiting valve 3.
  • the pressure-limiting valve 3 limits the pressure in the high-pressure accumulator 4 and short-circuits the pressure side of the high-pressure pump 2 with the storage container 1 as soon as the high-pressure accumulator 4 has reached its desired boost pressure.
  • High-pressure pump 2, pressure-limiting valve 3 and high-pressure accumulator 4 together form a high-pressure source 5, the pressure of which is used for the function of the entire brake system.
  • the high-pressure source 5 is connected via a priority valve 6 to a metering valve 7, which supplies the pressure to a hydraulic control unit 8 depending on the actuation of a brake pedal 9.
  • the priority valve has the task of providing a level control system NR with the high pressure of the high pressure source 5 only if this high pressure does not cause braking - be it with or without Pedal actuation - is required.
  • the priority valve 6 on the one hand feeds the metering valve 7, which forwards the brake pressure to the hydraulic control unit 8 depending on the pedal travel, and on the other hand the pressure line 10, which is led directly into the hydraulic control unit 8 bypassing the metering valve 7.
  • the pressure line 10 also has a safety accumulator 45, which is able to provide a reserve pressure if the priority valve 6 should switch incorrectly and the high pressure of the high pressure source 5 is not available.
  • the metering valve 7 also has a relief line 13, into which a relief line 14 of the level control NR opens.
  • the relief line 13 leads to the reservoir 1. It serves to reduce the brake pressure when the brake pedal 9 is released.
  • Two symmetrically constructed brake circuits I and II extend from the metering valve 7, the brake lines 11 and 12 of which also lead into the hydraulic control unit 8.
  • the brake line 11 is divided into two brake branches 16 and 17 at a node 15.
  • the brake branch 16 leads via an inlet valve 18 to the wheel brake 20 of a non-driven wheel.
  • the brake branch 17 passes through a separating valve 22 and leads via an inlet valve 19 to the wheel brake 21 of a driven wheel.
  • outlet lines 23 and 24 lead via an outlet valve 25 and 26, respectively, into a main outlet line 27, which opens into the relief line 13.
  • These outlet lines 23, 24 and 27 serve to reduce the brake pressure as part of a slip control.
  • the pressure line 10 is provided within the hydraulic control unit 8 with an electromagnetically actuated, normally closed 2-2-way valve 28 and, downstream of this check valve 28, is divided into two pressure branches 29 and 30.
  • Each of the pressure branches 29 and 30 is provided with a check valve 31 or 32 which prevents pressure medium from flowing back to the pressure line 10.
  • the pressure branch 29 opens into the brake branch 17 between the isolating valve 22 and the inlet valve 19. Accordingly, the pressure branch 30, which is assigned to the brake circuit II, opens into the associated brake circuit 33, which leads to the wheel brake 34 of a driven wheel.
  • the brake system shown in the case of a diagonal brake circuit division, permits active braking by the high-pressure source 5, bypassing the metering valve 7, only into the wheel brakes 21 and 34 of an axle. If the possibility of active braking for both wheels of a brake circuit is to be realized, then only the brake branches 16 and 35, which lead to the wheel brakes 20 and 36 of the additionally actively braked wheels, have to be on the other side of the isolating valve 22 and 37 from the brake line Branch 11 or 12. This means that the isolation valves 22 and 37 are then arranged in the brake lines 11 and 12 and the nodes 15 and 38 are shifted to the other side of the isolation valves 22 and 37, respectively.
  • valve combination 40 As an alternative to the illustrated valve combination 39 consisting of shut-off valve 28 and check valves 31 and 32, a valve combination 40 according to FIG. 2 can also be used in the circuit diagram of FIG. 1.
  • the pressure line 10 is not provided with a check valve in this version, but the Pressure branches 29 and 30.
  • Each of the two check valves 41 and 42 is an electromagnetically operated, normally closed 2-2-way valve.
  • the valve arrangement 40 is also suitable for a brake system which allows active braking in the wheel brakes of both axles.
  • the check valves 28, 41 and 42 remain closed with each pedal-operated braking. Therefore, the safety store 11 between the priority valve 6 and the metering valve 7 cannot discharge unless the level control system NR requires pressure medium from the safety store 11. Basically, however, the high pressure from the high pressure source 5 is provided.
  • the pressure control on the wheel brakes 20, 21, 34, 36 takes place in a manner known per se via the inlet valves and the outlet valves of the hydraulic control unit 8.
  • the brake systems according to FIGS. 1, 2 or in a modified form with a possibility for active braking on both vehicle axles thus have the advantage that a reliable circuit separation is effected by the valve arrangements 39 and 40, so that a single high-pressure source 5 for all purposes the brake application is sufficient.

Abstract

L'invention concerne un système de freinage hydraulique à double circuit, pour véhicules automobiles, comportant une source haute pression hydraulique (5) dont la pression peut être acheminée dans deux circuits de freinage (I et II) par l'intermédiaire d'une soupape de dosage (7) actionnée par la pédale. L'avantage de ce type de système réside dans le fait qu'une seule source haute pression suffit pour chaque type de freinage, à savoir l'antiblocage et l'antipatinage ainsi que le freinage normal. Afin de permettre un freinage actif dans les deux circuits de freinage, il doit être possible de raccorder la source haute pression aux deux circuits de freinage en contournant la soupape de dosage (7), tout en conservant la séparation des deux circuits. Ce but est atteint au moyen d'un ensemble soupape (39) présentant, dans la conduite de pression (10) menant de la source haute pression (5) aux circuits de freinage (I et II), une soupape d'arrêt en aval de laquelle la conduite de pression (10) se divise en deux ramifications (29, 30). Les ramifications sont équipées de soupapes anti-retour (31, 32) qui empêchent un reflux du fluide sous pression. Il est également possible d'équiper chaque ramification (29, 30) d'une soupape d'arrêt.
