- the sensor bore 31 is above or below the master cylinder bore 9 in a center plane of the hydraulic block 1 between tween the engine side 7 and the opposite control unit side 15 is arranged.
- Another possibility are two sensor bores 31 parallel to the master cylinder bore 9, which, starting from the opposite fastening sides 13, extend beyond the central plane 24 into the hydraulic block 1.
- the two sensor bores 31 are offset from one another in the circumferential direction of the main brake cylinder bore 9, so that they do not open into one another.
- one of the two sensor bores 31 is drawn with dashed lines, which is offset in the circumferential direction of the master cylinder bore 9 to the right.
- the sensor bore 31, which is not visible in the opposite fastening side 13, is preferably arranged in a mirror-inverted manner, that is to say on the opposite side of the center plane between the motor side 7 and the control unit side 15.
- a box-shaped control unit housing 33 is attached to the control unit side 15 of the hydraulic block 1, the open side of which faces the hydraulic block 1 and is closed by the hydraulic block 1. In Figure 3, the control unit housing 33 is not shown.
- the control unit housing 33 covers the external force cylinder 5, the cylinder 21 of the pedal travel simulator 17, the Ven tildome 23 ", 27" and the pressure sensors 25, 26 and protects them by sealing on the control unit side 15 of the hydraulic block 1 from water and corrosion.
- a printed circuit board 34 with one or more integrated circuits, microprocessors and / or other electronic components is arranged, which form an electronic control unit 35.
- the electronic control unit 35 receives signals from, among other things, the pressure sensors 25, 26 and the electric motor 6 of the external power brake pressure generator 8 and controls or regulates the electric motor 6, the solenoid valves 22, 23, 27 and the like hydraulic components of the brake pressure control and slip control.
- the electronic control unit 35 is the same regardless of which of the two opposing fastening sides 13, 13 'is used to fasten the hydraulic block 1.
- the control device 35 used is independent of which of the two opposite fastening sides 13, 13 'of the hydraulic rocker 1 is or will be attached. This applies in any case to the hardware of the control device 35; the software can be adapted.
- the hydraulic block 1 can be fastened and used with one and the same electronic control unit 35 either on the first fastening side 13 or on the opposite second fastening side 13 '.
- a multi-pole electrical plug connection 36 for the electronic control unit 35 and a power supply for the electric motor 6 is integrally formed on the control unit housing 33.
- the plug connection 36 is located under the lower transverse side 18 of the hydraulic block 1 and is accessible from the direction of the engine side 7 for inserting a mating connector not drawn.
- the holes can have internal threads for connection of brake lines with screw nipples or threadless for connection of brake lines with nipples by caulking, in particular with self-clinch nipples, which are caulk pressure-tight when pressing into the material holes.
- the brake lines are another hydraulic block, not shown, which has some of the hydraulic components of the external power vehicle brake system 3, or wheel brakes can be connected to the hydraulic block 1. So that the brake line connections 37 are easily accessible on the hydraulic unit 2, for example, in the engine compartment, they are as far away as possible from the attachment side 13, 13 ', with which the hydraulic block 1 is attached to the bulkhead of the vehicle, not shown, for example.
- two brake line connections 37 are provided on a side of the center plane 24 of the hydraulic block 1 facing away from the first fastening side 13 for fastening the hydraulic block 1 or hydraulic unit 2 to the first fastening side 13 in FIG. Because there is too little space for two brake line connections 37 on the first fastening side 13 facing side of the center plane 24, the hydraulic block 1 has only one brake line connection 37 on the side facing away from the second fastening side 13 'for fastening to its second fastening side 13' Central plane 24, which is drawn in Figure 1 with broken lines.
- One of the two brake line connections 37 on the side of the center plane 24 facing the second fastening side 13 ′ is used as the second brake line connection 37, namely the brake line connection 37, which is further away from the second fastening side 13 ′.
