Problems solved by technology

[0003] Electromagnetic interference immunity of the pump motor is more difficult in the hydraulic modulator and thus in the entire vehicle interior, since relatively high currents must flow here for the operation of the pump motor

Embodiment Construction

[0022] The figures each show a hydraulic modulator 10 which has as main component a pump motor 12 which has a pump housing 14 at least partially surrounding it. On the pump motor 12 , an electrical connection terminal 16 protrudes through the pump housing 14 , where it has two electrical connection leads 18 protruding from the pump housing 14 , which are contact pins. Furthermore, these contact pins extend to the controller 22 through holes 20 formed in the pump housing 14 . The electrical connecting wire 18 is electrically connected to the controller 22 by means of an elastic bow clip 24 .

[0023] For the electromagnetic anti-interference of this hydraulic modulator 10, each has an electromagnetic anti-interference circuit 26 to be pushed onto the electrical connection lead 18, and this electromagnetic anti-interference circuit is electrically connected with the electric connection lead of the pump motor 12 on one side, and the other side is connected with the electric conne...

Abstract

The present invention relates to a hydraulic power pack (10) for hydraulic braking system of vehicle. The pack has a pump motor (12) and an electroconducting pump housing (14) partially surrounding the motor, a control apparatus (22), and at least an electric connecting link (18) is installed between a control apparatus (22) and the motor (12). According to this invention, there is an electromagnetic interference suppression circuit (26) in the hydraulic power pack, which is connected between the link (18) and the housing (14).

Description

technical field [0001] The invention relates to a hydraulic modulator for hydraulically controlling the braking device of a vehicle, which comprises a pump motor, a conductive pump housing at least partially surrounding the pump motor, a controller, and at least one electrical connection wire between the control device and the pump motor . Background technique [0002] In hydraulically controlled vehicle brake systems, as is currently used for motor vehicles, hydraulic modulators are used, by means of which hydraulic system fluid can be supplied and / or pumped to the corresponding wheel brakes of the motor vehicle, in particular with assistance export. In order to obtain the auxiliary force, a pump is provided in the hydraulic modulator, which pump can be selectively driven by the pump motor. The operation of the pump is regulated by means of a controller, which is operatively connected to the pump motor via at least one electrical connection line. [0003] Since relativel...
