  • brake systems are known, for example, from DE 42 32 311 Cl and from DE 43 29 139 Cl. In both cases, these are brake systems which are suitable both for brake slip control and for automatic brake actuation.
  • During a brake slip control they operate according to the return feed principle.
  • the two return pumps of the anti-lock control are used as pressure sources for the automatic activation of the wheel brakes.

  • the pressure outputs of the return pumps are shut off against the pressure outputs of the precharge cylinders and the latter to the suction sides of the return pumps.
  • the precharge cylinders are both actuated by a common precharge pump, which acts on the piston surfaces of the precharge cylinder with their delivery pressure.
  • the precharge pump is connected to the reservoir with its suction side.
  • the pressure of the charging pump initially closes a seat valve, as in the case of a master cylinder, which blocks the connection from the pedal-operated master cylinder to the wheel brakes.
  • a pressure is then built up in the brake line, which pressure is also available on the suction side of the return pump.
  • the precharge cylinders of the two publications differ in that DE 42 32 311 Cl has two separate precharge cylinders, each with a drive pressure chamber, the drive pressure chambers being connected to the precharge pump via a common pressure line, while in DE 43 29 139 the two precharging cylinders have a common, centrally arranged drive pressure chamber which is connected to the pressure side of the precharging pump.
  • the corresponding pistons of this precharging device move apart as soon as the precharging pump builds up pressure.

  • the principle of the present invention is to arrange the precharging pump above the master cylinder, so that the feature of a closed brake system is provided without further design measures.
  • Such an arrangement of the precharge pump above the master cylinder is not limited to those brake systems in which precharging is required in both brake circuits, but can also be used for those brake systems in which only the return pump of a brake circuit has to be precharged .
  • the precharging pump is functionally connected in parallel with the switching valve between the master cylinder and the container and thus a short circuit of the precharging pump is made possible as long as no pre-pressure is required, the precharging pump can convey pressure medium in a circuit without great energy loss. This has the advantage that the precharging pump can be started even before the need for a precharge and that only the switching valve has to be closed in order to provide the precharge of the precharging pump immediately. In this case, the precharge pump does not have to start up.
  • the return pump is optimized for achieving high delivery pressures and can therefore only deliver a comparatively small volume flow.
  • the precharge pump delivers a maximum volume flow at low pressures. This is particularly important when initiating an automatic braking process if the air clearances of the wheel brakes concerned must first be overcome.

Abstract

Pour précharger les pompes de refoulement (17) à auto-amorçage d'un système de freinage à régulation antipatinage, par exemple à des températures basses, il est prévu de monter une pompe de suralimentation (28) entre le réservoir (22) et le maître-cylindre (1), qui refoule un fluide hydraulique dans un ou dans les deux raccords d'alimentation (23, 24) du maître-cylindre (1). Le fluide hydraulique parvient côté aspiration des pompes de refoulement (17) par commutation d'une électrovanne de commutation (19) et d'une électrovanne de séparation (4). Pour un freinage normal, il est prévu une liaison munie d'une soupape de commande (27), entre le réservoir (22) et le maître-cylindre (1). Cette soupape de commande (27) est fermée à des fins de précharge de la pompe de refoulement (17). La soupape de commande (27) peut être une électrovanne ou une soupape à actionnement hydraulique.
