Embodiment Construction

[0024] figure 1 and 2 A hydraulic system 10 of a vehicle brake system (not shown) is shown, which comprises a square hydraulic block 12 and a drive motor 14 which is fastened externally to this hydraulic block 12 . The drive motor 14 has a cup-shaped motor housing 16 , which is fastened in a conventional manner to the side of the hydraulic block 12 by means of at least two screws 18 and thus holds the drive motor 14 on the hydraulic block 12 .

[0025] The drive motor 14 drives a motor shaft 20 , which protrudes through a bore 22 into the hydraulic block 12 and is mounted in the hydraulic block 12 by means of a motor shaft bearing 24 . Furthermore, bearing caps 26 are provided as A bearing caps for delimiting the motor interior 28 , for accommodating the motor shaft bearing 24 and for pre-centering the drive motor 14 prior to assembly on the hydraulic block 12 .

[0026] Attached to the motor shaft 20 is an eccentric 30 which, during operation, rotates together with the moto...

Abstract

The invention relates to a hydraulic unit for vehicle brake system with motor bearing, and provides a hydraulic unit (10) of a vehicle brake system having a hydraulic block (12) and a drive motor (14) externally arranged on the hydraulic block (12) for driving at least one pump element (36) and a motor shaft (20) is supported on the hydraulic block (12) by means of a motor shaft bearing (24), the motor shaft bearing (24) is fixed to the hydraulic block (12) with a wedge member (40).

Description

technical field [0001] The invention relates to a hydraulic system of a vehicle braking system with a hydraulic block and a drive motor, which is arranged on the outside on the hydraulic block for driving at least one pump element and whose motor shaft is supported by means of a motor shaft bearing on the hydraulic block. Furthermore, the invention relates to the use of such a hydraulic device in a vehicle braking system. Background technique [0002] A hydraulic system is used in a vehicle brake system to be able to provide a brake pressure regulated by means of brake fluid in an associated brake circuit. For adjusting the brake pressure, the hydraulic system includes a hydraulic block or a block-shaped housing in which a plurality of bores are arranged. These housings also serve as pump housings for the corresponding pump elements. The individual pump elements are formed by a pump piston and a pump cylinder, in which the pump piston is mounted so as to be movable back a...
