Abstract

A cuboid hydraulic block of a slip control system of a hydraulic vehicle brake system has a lateral face, an opposite lateral face, at least two long sides, a short side, and an opposite short side. All receptacles for solenoid valves of the slip control system are disposed in the lateral face of the hydraulic block. Receptacles for hydraulic accumulators of the slip control system and connecting bores for a master brake cylinder are disposed in the opposite lateral face of the hydraulic block. Receptacles for hydraulic pumps of the slip control system are disposed in the long sides of the hydraulic block. An electric motor for driving the hydraulic pumps is disposed on the short side of the hydraulic block. Connecting bores for wheel brakes are disposed in the opposite short side of the hydraulic block.

First claim

The invention claimed is:

1. A cuboidal hydraulic block for a hydraulic assembly of a slip control system of a hydraulic vehicle brake system, comprising:
a first large side;
two opposing longitudinal sides adjacent to the first large side;
two opposing transverse sides adjacent to the two longitudinal sides, at least one of the two transverse sides being adjacent to the first large side;
a plurality of first receptacles defined in the first large side of the hydraulic block, the plurality of first receptacles configured for valves of the slip control system, the plurality of first receptacles including:
four inlet valve receptacles configured to receive inlet valves and arranged in a first row parallel to the two transverse sides;
four outlet valve receptacles configured to receive outlet valves and arranged in a second row parallel to the two transverse sides; and
two intake valve receptacles configured to receive intake valves and two isolating valve receptacles configured to receive isolating valves, the two intake valves and two isolating valves arranged in a third row parallel to the two transverse sides; and

at least one second receptacle disposed in at least one of the two longitudinal sides of the hydraulic block, each second receptacle of the at least one second receptacle configured for a hydraulic pump of the slip control system,
wherein a first transverse side of the two transverse sides of the hydraulic block is configured as a motor side for the attachment of an electric motor, the electric motor configured to drive the hydraulic pump arranged in each second receptacle.

2. The hydraulic block as claimed in claim 1 , further comprising an eccentric space defined in the motor side and configured for a pump eccentric, the pump eccentric configured to drive the hydraulic pump arranged in each second receptacle.

3. The hydraulic block as claimed in claim 1 , further comprising at least one third receptacle disposed in a second large side situated opposite the first large side.

4. The hydraulic block as claimed in claim 1 , further comprising:
a first connection bore disposed in a second transverse side situated opposite the motor side, the first connection bore configured to hydraulically connect to a hydraulic wheel brake; and
a second connection bore disposed in a second large side situated opposite the first large side, the second connection bore configured to hydraulically connect to a master brake cylinder.

5. The hydraulic block as claimed in claim 1 , wherein all receptacles configured for solenoid valves of the slip control system are disposed in the first large side.

6. The hydraulic block as claimed in claim 1 , wherein the at least one second receptacle includes a plurality of second receptacles, each second receptacle of the plurality of second receptacles configured to receive one of the hydraulic pumps of the slip control system.

7. The hydraulic block as claimed in claim 6 , wherein the hydraulic block has a thickness defined perpendicular to the first large side, the thickness being greater in a region of the one or more oblique second receptacles.

8. The hydraulic block as claimed in claim 6 , wherein one or more oblique second receptacles of the plurality of second receptacles are oblique with respect to the first longitudinal side, the two longitudinal sides, and the two transverse sides of the hydraulic block.
