Abstract:
A hydraulic system for a slip-regulated dual circuit braking system includes two separating valve receiving holes disposed between a plurality of wheel brake connections which open up into the receiving body and the valve receiving holes of a first valve series include a plurality of inlet valves.
Abstract:
A hydraulic unit for a slip-controlled braking system includes a housing body provided with a flange surface into which at least one additional bore joins. The bore, in addition to a cable through bore arranged in the housing body, is covered by an electromotor and/or a control device. The additional bore is either a leakage receiving bore or a noise reducing chamber.
Abstract:
The invention relates to an electrohydraulic assembly for an electronically controlled brake system with an accommodating member which includes accommodating bores for electrohydraulic valves, accommodating bores for hydraulic supply devices and an accommodating bore for at least one roller bearing, and with hydraulic channels and pressure fluid ports, as well as with an electric motor comprising a rotor with a shaft that is mounted with the roller bearing in the associated accommodating bore in the accommodating member and used to drive the supply devices, and with an electronic control unit being connected to the electric motor by means of a plug penetrating a through-bore in the accommodating member.The objective is to provide a safe and comfortable operating characteristics even in consideration of extreme environmental influences.This object is achieved because the electrohydraulic assembly includes at least two brake circuits and at least two supply devices per brake circuit, and because the accommodating bores for the supply devices are arranged on top of each other along a first imaginary plane that extends in parallel to the shaft.
Abstract:
A trailer device for driving stabilization of vehicle combinations is provided. In order to design a device for driving stabilization of passenger vehicle trailers in a cost-effective and simple manner, a brake system for braking the trailer by an overrun brake and for stability regulation is designed so as to have separating valves, switching valves, inlet and outlet valves and a pressure build-up pump. A stabilizing coupling is also connected by means of a second pressure medium pump to actuators which can vary the clamping force of the stabilizing coupling between the trailer and tractor vehicle if the second pressure medium pump conveys pressure medium from the storage tank into or out of the actuators.
Abstract:
An electrohydraulic unit assembly for a motor vehicle comprising a receiving body defining a sealing face and at least two connectors fastened to the receiving body of the unit, oriented substantially parallel one to another and separated by a defined distance from one another. Each connector is configured for connecting a fluid conduit to the unit. Each connector includes a screw fitting for fastening the respective hydraulic connection to the receiving body of the unit such that a sealing face of the screw fitting or a sealing face of the fluid conduit is seated on the sealing face of the receiving body. Each screw fitting is rotatably connected to the body and includes two spanner flat portions having different spanner widths.

The objective is to provide a safe and comfortable operating characteristics even in consideration of extreme environmental influences. This object is achieved because the electrohydraulic assembly includes at least two brake circuits and at least two supply devices per brake circuit, and because the accommodating bores for the supply devices are arranged on top of each other along a first imaginary plane that extends in parallel to the shaft.
Abstract:
The present invention discloses a hydraulic fluid accumulator comprising a housing having an interior subdivided into three chambers, with the first chamber being filled with a gas and separated from the second chamber by a first media separation element, the second chamber being filled with a fluid and separated by a second media separation element from the third chamber that is also filled with a fluid and connected to a hydraulic port. To safeguard an effective separation of media within the hydraulic fluid accumulator and, thus, a significant increase in its functional safety, the present invention arranges for the second media separation element to be embodied by a metal piston delimiting a chamber that can be vented in the housing.

Abstract:
A conveying device for a vehicle brake system, to convey pressure fluids into at least one vehicle brake, or to convey pressure fluids into a pressure fluid accumulator, or to convey pressure fluids into a master brake cylinder with at least one moveable piston (2) in a receptacle (4) to displace pressure fluids from a working chamber (5′), has at least one non-return valve (9, 9′) to vent the working chamber (5) and to temporarily separate a hydraulic connection between the working chamber (5) and a hydraulic channel, whereby the non-return valve (9) must have at least one valve seat (11) and one valve body (12).To achieve the simplest possible assembly of the non-return valve (9), the valve seat (11) is assembled from several special valve seat segments (13,14).
Abstract:
Disclosed are hydraulic/electronic control units (1, 2) for an electronic brake control system. A hydraulic/electronic control unit of current ABS/TCS/ESP systems essentially includes a central hydraulic block (6) and an electronic control unit (1) including control electronics on a control circuit board (4). The circuit board (4) is structured in such a way that it is insulated completely towards the outside on at least one first side (28) and includes an essentially smooth surface. Thus it is possible to use the hydraulic block (6) for cooling the circuit board (4).
