摘要:
In order to minimize the vacuum-dependent force component acting upon the valve body of a vacuum brake booster that is equipped with a pneumatically pressure-compensated control valve without requiring constructive modifications of the valve gear casing that accommodates the control valve, the invention includes a radially inner limit as well as the radially outer limit of a pressure compensation chamber in the valve gear casing, which is limited by the valve body, is formed by a guide part that guides the valve body.

A compact hydraulic unit for slip-controlled brake systems with several hydraulically, mechanically and/or electrically operable functional elements (e.g. accumulator, valve elements, pressure generating and driving elements) arranged in an accommodating member, with several pressure fluid channels connecting the functional elements. The pressure fluid channels create a hydraulically operable connection between at least one pressure fluid supply means and one pressure fluid consumer. A control device can be connected with the valve and the driving elements by means of electrical conductors. The valve elements are arranged in several valve accommodating bores of the valve accommodating member in a first and a second row. Pressure fluid bores are provided between the two diametrically extending valve rows which connect the valve elements and location bores containing the pressure generating element and the driving element. Outside the two valve rows, there are further location bores in the valve accommodating member in which pressure accumulator pistons are positioned.

The present invention relates to a hydraulic brake system with slip control, including a brake line which connects a braking pressure generator to several wheel brakes, at least one pressure modulation valve associated with each wheel brake to control the hydraulic connection to the wheel brake, a pump which supplies stored pressure fluid to the wheel brakes by way of a pressure fluid collecting means connected to a suction line, and sensors to determine the rotational speed of the wheels and an evaluating circuit to control the wheel slip. The pressure fluid connection between the braking pressure generator and the wheel brakes is established by a brake line, to which the pump is connected, wherein a multi-way valve and a monitoring device including a pressure sensor is inserted into the brake line to sense the pressure prevailing at the pressure modulation valve of the wheel brake.

A circuit arrangement for a brake system with electronic brake force distribution control includes circuits which determine the deceleration of the rear wheels and the deceleration of a vehicle or a corresponding reference quantity. The discrepancy of the filtered rear-wheel deceleration from the vehicle deceleration is evaluated for brake force distribution control. To this end, an output signal is produced by way of a differentiator and integrator comparing the rear-wheel deceleration and the vehicle deceleration, and the output signal is evaluated for the control of the braking pressure in the rear-wheel brakes.

A reset device for a blinker switch includes a pivoting reset element which is used which has two lateral arms on which opposing springs extending through the switch housing act. These springs both tension the reset element with respect to the steering spindle and produce a torque tending to restore the reset element to its middle setting. The problem of the invention is to do without the conventional draw springs. The invention solves this problem by means of a single compression spring acting on the reset element and providing both a force in the longitudinal direction of the reset element and the desired restoring torque.

An electromechanically actuated disc brake system for motor vehicles comprising a floating caliper and an actuating unit mounted with the caliper. The actuating unit is an electric motor which, by interpolation of a reducing gear, powers an actuating element, which in turn controls one of two sliding friction linings mounted inside the brake caliper, to interact with the disc brake. With the intent to reduce axial dimensions of the actuating unit, the present invention includes an electric motor with a rotor of ring-shaped design to radially surround the reducing gear.

A driving crank for a windshield wiper system, wherein the crank lever is made of deep-drawn sheet metal. The crank lever has a rear part and a circumferential edge beaded towards one side of the rear part. At one end, the crank lever has an opening with an edge beaded towards the same side so as to form an inner cone. To prevent the inner cone from expanding and to reliably transmit high torques between the driving crank and the shaft to be secured in the opening, and vice-versa, the inner cone is expanded from the rear part.

A brake unit for motor vehicles with electric drive with a hydraulic pressure transducer and hydraulic friction brakes to increase the brake effect applied by the electric drive motor. The cooperation of the electric drive motor with the hydraulic friction brakes is controlled by an electronic controller. To increase the reliability of operation of the brake unit by making possible the buildup of hydraulic pressure in the friction brakes associated with the driven axle in the case of a failure of the electronic controller or of the entire electric system of the vehicle, the pressure transducer is arranged as a two-circuit main brake cylinder, to the first pressure space of which the friction brakes acting on the nondriven axle, and to the second pressure space of which the friction brakes acting on the driven axle are connected, wherein the connection between the second pressure space and the friction brakes acting on the driven axle is by at least one shut-off valve, which can be switched over electrically and is open in the currentless state.

A water- and/or dust-tight toggle switch has an LED switch. The LED or other luminous elements are impermeably shielded from the surroundings by a housing of a comparatively simple design. The housing is provided with cast windows which make possible light output from the luminous element disposed within the interior of the housing. Favorable refinements pertain to the arrangement of a light guide on the actuator cap and also the protection of the inserted plug through extended, guided-down housing walls.
