Abstract
A hydraulic block of a slip control system of a hydraulic vehicle brake system includes a hydraulic accumulator, a hollow storage cover, and an accumulator cylinder defined partly by a blind hole in the hydraulic block and partly by the hollow storage cover. The blind hole is closed by the hollow storage cover. An accumulator piston of the hydraulic accumulator is sealed and guided to or close to the ends in the blind hole in the hydraulic block and in the storage cover.
Claims6
A hydraulic block for a hydraulic assembly of a brake control system of a hydraulic vehicle brake system, comprising:
- a hydraulic accumulator including:
- a hollow accumulator cover arranged on the hydraulic block so as to protrude from the hydraulic block;
- an accumulator cylinder defined partly by a blind hole in the hydraulic block and partly by the hollow accumulator cover;
- and
- an accumulator piston received in an axially movable fashion in the accumulator cylinder,
- wherein the accumulator cover guides the accumulator piston at a first end portion facing away from the hydraulic block, and
- wherein, at a second end portion facing the hydraulic block, the accumulator piston is sealed and guided in the blind hole of the hydraulic block.
A method for mounting a hydraulic accumulator on a hydraulic block for a hydraulic assembly of a brake control system of a hydraulic vehicle brake system, the method comprising:
- inserting an accumulator piston of the hydraulic accumulator in a blind hole in the hydraulic block that partly defines an accumulator cylinder in a such a way that the accumulator piston is axially movable in the accumulator cylinder and is guided at a second end portion of the accumulator piston by the blind hole;
- and
- placing an accumulator cover, which is radially movable relative to the blind hole in the hydraulic block until the accumulator cover is secured to the hydraulic block and which partly defines the accumulator cylinder, on an end of the accumulator piston facing away from the hydraulic block such that the accumulator cover protrudes from the hydraulic block;
- coaxially orienting the accumulator cover with the accumulator piston;
- and
- securing the accumulator cover to the hydraulic block such that the accumulator cover guides the accumulator piston at a first end portion of the accumulator piston that faces away from the hydraulic block.
