摘要:
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.

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.

A pump unit for a hydraulic vehicle brake system with traction control has an electric motor driving a radial piston pump. A rotor shaft of the pump unit has a hollow shaft with two standardized, hardened cylindrical pins that are press-fitted into the ends of the hollow shaft. The rotor shaft can be produced simply, economically, and without metal-cutting machining. The hollow shaft has high bending and torsional strength. The rotor shaft has a small diameter at the bearing points, which makes a small bearing diameter and thus a small installation space for the pump unit possible.

A piston pump for a hydraulic brake system for a vehicle with a slip control system. For economical production, the piston pump includes a piston as a composites part with a core of steel that is surrounded by a lubricant jacket of plastic. By way of example, the lubricant jacket is applied to the core by spray-coating, or is pressed onto the core or slipped onto the core. The lubricant jacket economizes by dispensing with expensive post-machining of the piston surface by grinding, for instance, and improves the sliding properties of the piston.

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 clamping means disposed on the bolt, the elastomer element is axially shortened and pressed against both the recess and side faces, located on either side of the recess, of the leg of the mounting bracket. With the shortened elastomer element, a positive and nonpositive engagement with the leg of the mounting bracket is achieved.

Pressure pulsations are damped in and a hydraulic unit by a device including a housing with an inlet and an outlet having a throttle and a filter preceding the throttle. The filter and the throttle are combined into a one-piece function element, which can be produced without metal-cutting machining and which can be fixed in the interior of the housing. This preceding filter prevents clogging of the throttle by contaminants in the pressure fluid, without requiring additional expense for parts or assembly. The function element can be produced economically in a minimum number of work steps, can be manipulated without problems, and in an advantageous refinement makes it possible to avoid unwanted accumulations of air in the device.

In a pump housing, in block form, of a vehicle brake system, having a top side which is manufactured to final dimensions and a bottom side which is manufactured to final dimensions, the final dimensions of the top side and of the bottom side are obtained by means of a non-cutting deformation process starting from a blank.

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 bloc 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.
