Abstract

A hydraulic automotive vehicle brake system with brake slip control and automatic brake management for traction control and/or driving dynamics control includes a braking pressure generator which is hydraulically connectable to at least one wheel brake and a pressure fluid accumulator by way of pressure modulation valves, at least one pump which is connected with its suction side to a pressure fluid accumulator and with its pressure side to a pressure fluid conduit that extends from the braking pressure generator to the wheel brake, the pressure fluid conduit comprising the pressure modulation valves and a pressure sensor that is connected to the pressure fluid conduit in between the braking pressure generator and the pressure modulation valves. The pressure sensor is accommodated in a housing which houses the pressure modulation valves.

Claims

1. A hydraulic automotive vehicle brake system with brake slip control and automatic brake management, including a braking pressure generator which is hydraulically connectable to at least one wheel brake and a pressure fluid accumulator by way of pressure modulation valves, at least one pump which is connected with its suction side to the pressure fluid accumulator and with its pressure side to a pressure fluid conduit that extends from the braking pressure generator to the wheel brake, the pressure fluid conduit comprising the pressure modulation valves and a pressure sensor that is connected to the pressure fluid conduit in between the braking pressure generator and the pressure modulation valves, the pressure sensor being accommodated in a housing which houses the pressure modulation valves,

wherein a cover is attached to the housing and is arranged on the pressure modulation valves and the pressure sensor, and wherein the cover includes a carrier plate, the carrier plate providing an electrical connection to the pressure sensor.

2. The brake system as claimed in claim 1,

wherein a plug connector is fitted between the cover and the pressure sensor.

3. The brake system as claimed in claim 2,

wherein a profile seal is interposed between the plug connector and the pressure sensor.

4. The brake system as claimed in claim 1,

wherein the pressure sensor includes in a sensor housing a capacitive transducer which is connected to electric and/or electronic components.

5. The brake system as claimed in claim 1,

wherein the pressure sensor and the pressure modulation valves are attached in parallel stepped bores of the housing by way of a self-caulking engagement.
