Abstract: The invention relates to a hydraulic braking system having a device for controlling brake slip, drive slip, and/or the driving stability of a vehicle. Among other things, such devices use pumps, valves, and reservoirs to control brake pressure in the wheel brakes in accordance with wheel slip occurring at the particular wheels. These components are in contact with each via a hydraulic circuit. The hydraulic circuit is built into a hydraulic block that has spaces for installing the components and channels for hydraulic contact. The invention makes possible a particularly compact and reduced-weight design of the hydraulic block and at the same time low manufacturing costs. For this purpose an advantageous layout and sealing of channels relative to each other and to the surrounding area is provided.

Abstract: The invention relates to a device for suspending a unit, especially a hydraulic unit of an electronically traction-controlled brake system of a motor vehicle. The unit is suspended in a receptacle provided on the vehicle such that vibrations are damped. Hydraulic units of vehicle brake systems are usually equipped with an electric motor for driving pumps located in the hydraulic unit. The brake pressure in the wheel brakes can be modulated via the pumps. The pump drive can cause mechanical and hydraulic vibrations in the unit which can result in unwanted operational noise in case the vibrations are transmitted to the vehicle body without being damped. The improved device is manually preloaded due to limited space for using tools. A clamping mechanism is guided in an axially movable manner on an armature which is fixed to the hydraulic unit and which can be moved from a basic position into a clamping position. The clamping mechanism is interlocked with the armature in both positions.

Abstract: The invention relates to a hydraulic vehicle brake system having a service brake which can be actuated by muscle force and having a device for regulating the wheel slip. It is proposed in such a vehicle brake system to use suction pumps in connection with specially-designed accumulators. The accumulators have separating elements which in each case separate a first accumulator chamber from a second accumulator chamber. An inflow opens out into the first accumulator chamber, and an outflow, which is separate from the inflow, outlets out of the first accumulator chamber. The separating element is arranged so as to be freely movable between two end positions, and in one of its end positions, blocks a pressure medium connection of the inflow to the outflow.

Abstract: The invention relates to a hydraulic assembly of a vehicle brake system with traction control. Hydraulic assemblies include a housing block, which is to be fitted with hydraulic components, and an electronic control unit for activating the components. It is known for a hydraulic connection for a pressure sensor to be provided on a housing block and for the signal of the pressure sensor to be taken into consideration for brake pressure regulation in the control unit. The invention proposes an advantageous arrangement of at least one second hydraulic connection for a second pressure sensor on the housing block in combination with blind bores of the hydraulic connections. The blind bores can be positioned in a variable fashion and formed with different lengths during the production of the housing block. In this way, it is possible for the pressure in different hydraulic partial regions of a vehicle brake system to be sensed in an application-specific manner.

Abstract: The invention is based on a hydraulic unit for regulating the brake pressure in a vehicle brake system. Hydraulic units of such a type are the core component of an anti-lock vehicle brake system, of a drive slip vehicle brake system or of a vehicle brake system which regulates driving stability.

On account of the arrangement, the housing block can be reduced in terms of its dimensions, and can be produced with a lower weight and more simply in terms of production. For this purpose, according to the invention, the pressure fluid connection from one of the ports of the master brake cylinder to the suction side of one of the pump elements extends through the valve receptacle of the switching valve.

The control unit housing and the hydraulic assembly housing form a receiving chamber with a covering for at least one electrical component. The at least one electrical component is arranged in the receiving chamber in a sealed manner at least in the region of contact faces between the component and the chamber. For each component, one seal is applied in a fluid process and is assigned individually to the relevant electrical component to be arranged. The seal is applied in the region of the contact faces between the component and the covering of the electrical component, the control unit housing, and the hydraulic assembly housing.

Abstract: A hydraulic unit is elastically supported by means of elastomer elements, through which bolts pass, on two legs of a mounting bracket that extend perpendicular to one another. The leg of the mounting bracket has recesses, open counter to the mounting direction of the unit, for receiving the elastomer element.

With the shortened elastomer element, a positive and nonpositive engagement with the leg of the mounting bracket is achieved.

Abstract: A pressure fluid reservoir for a traction-controlled vehicle brake system; a reservoir unit including a plurality of pressure fluid reservoirs; and a method for producing a pressure fluid reservoir are disclosed. The pressure fluid reservoir with its structural size unchanged, has a larger installation space for a restoring element cooperating with a reservoir piston and at the same time can be produced economically. To that end, as the reservoir piston, a component reshaped in non-metal-cutting fashion from a sheet-metal material is proposed, on whose circumference an encompassing receptacle for a piston seal is integrally formed, likewise in non-metal-cutting fashion. The reservoir piston can be produced by deep drawing; the receptacle for the piston seal can be produced by roller-burnishing. Both method steps can be performed economically in one combined operation.

Abstract: A vibration-damping device for mounting a unit on a mounting face, including a bell-shaped housing, a damping body of vibration-damping material disposed in the housing, a rigid core received in the damping body, and fastening means associated with both the core and the housing. The damping body is cup-shaped and offset in its outside diameter at least once jointly with the core, and the open end of the housing is closed with a closure whereby a positive engagement is established among the components. As a result, the device is capable of damping tensile and compressive forces on the unit equally. The damping devices can be disposed on a common outside area of the unit.
