Problems solved by technology

However, this preferential treatment of the receiving opening for the delivery device results in a space-consuming positioning of the remaining components
This embodiment has the disadvantage that all other components with corresponding connecting channels have to be constructed to a certain extent around the receiving opening of the delivery device
This results in a correspondingly high cost and complexity of drilling technology

Embodiment Construction

[0025] according to figure 1 , the electrohydraulic braking system 1 comprises an actuating unit 2 with a master cylinder 3 and two wheel brakes FR, FL, RR, RL each arranged in two different hydraulic circuits, the wheel brakes being clustered ground and independently connected to the primary pressure chamber PC or the secondary pressure chamber SC of the master cylinder 3 .

[0026] In the connection between the master cylinder 3 and the wheel brakes FR, FL, RR, RL there is another hydraulic unit 4 with an electronic control unit ECU that can realize braking or driving anti-slip control. For this purpose, the hydraulic unit 4 comprises, in the receiving body 21, inlet valves 5-8, which are open when there is no current, and outlet valves 9-12, which are closed when there is no current, which are connected in pairs to the wheel brakes FR, FL, RR. , upstream of RL.

[0027] By activating the outlet valves 9-12 which are closed when there is no current and discharging the hydr...

Abstract

The invention relates to a hydraulic unit for slip-controlled braking systems having a plurality of receiving holes (23-28) for transport devices (15a, 15b, 15c; 16a, 16b, 16c) associated with a plurality of hydraulic circuits bundled into groups, wherein the receiving holes (23-28) are disposed at a distance from each in parallel with the upper side (22), and a drive shaft having eccentrics located at the plane spacing for driving the transport devices (15a, 15b, 15c; 16a, 16b, 16c). In order to provide a compromise optimized for manufacturing a small, convenient hydraulic unit, it is proposed according to the invention that three theoretical planes (E1, E2, E3) are arranged in parallel to the upper side (22), each receiving two V-shaped receiving holes for transport devices (23-28) disposed at an angle to each other, and that the drive shaft comprises three separate eccentrics for driving said transport devices (15a, 15b, 15c; 16a, 16b, 16c).

Description

technical field [0001] The invention relates to a hydraulic unit having the features of the preamble of claim 1 . Background technique [0002] Units of this type are preferably used in electrohydraulic braking systems, in which the driver of the vehicle issues a braking request which is controlled by the braking system to a certain extent on the basis of corresponding actuators, preferably at Executed taking into account the detected environmental conditions. [0003] In electrohydraulic braking systems, pressure is built up in the wheel brakes either directly by means of a pressure source, usually in the form of a positive displacement pump device with pistons, or indirectly based on a pressure accumulator. These mechatronic systems always include complex electronic units with numerous software as well as complex hydraulic units based on hydraulic circuit structures (Schaltplan) and ensure suitable accommodation of the various hydraulic and electrohydraulic components con...
