| 20120013173 | BRAKE SYSTEM HAVING SIMULTANEOUS OR PARTIALLY SIMULTANEOUS PRESSURE GENERATION AND REDUCTION IN THE WHEEL BRAKES FROM DIFFERING WHEEL CYLINDER PRESSURE LEVELS - A braking system may include a brake booster, the piston-cylinder system of which is driven by an electric motor, wherein at least one working chamber of the piston-cylinder system is connected by hydraulic lines to at least two wheel brakes, a wheel brake being allocated a 2/2-way switching valve in each case and the hydraulic connection lines between the wheel brakes and the piston-cylinder system being closable, optionally separately or jointly, by means of the 2/2-way switching valves, so that a pressure can be adjusted in the wheel brakes one after the other in terms of a multiplex method and/or simultaneously, the electric motor and switching valves being activated by a control device, and in that the hydraulic connection line from the working chamber of the piston-cylinder system to the respective magnetic valve has a flow resistance RL | 01-19-2012 |
| 20110031072 | BRAKE SYSTEM WITH ADAPTIVELY CONTROLLABLE BRAKE LINING CLEARANCE - The invention relates to a hydraulic brake system comprising a master brake cylinder ( | 02-10-2011 |
| 20110006596 | BRAKE SYSTEM COMPRISING AT LEAST ONE CONVEYING UNIT FOR REDELIVERING BRAKE FLUID TO THE WORKING CHAMBERS OF A BRAKE BOOSTER - The invention relates to a brake system comprising an electromotive drive device for a brake booster having at least one piston, the at least one piston being driven by the drive device for pressure build-up and pressure relief in at least one wheel brake and being mechanically adjustable by means of a brake actuator, especially in the form of a brake pedal, only in the event of malfunction of the drive device, at least one decoupling valve for closing and opening the brake line being arranged in the brake line between every wheel brake and a working chamber of the brake booster. The brake system is characterized in that at least one delivery unit delivers, when required, brake fluid from a reservoir to the respective working chamber of the brake booster via at least one supply line that is connected to a brake line or the brake booster, especially to a working chamber, a controlled valve for opening and closing the respective supply line being arranged in every supply line. | 01-13-2011 |
| 20100089054 | ADAPTIVE FREE-TRAVEL REDUCTION - The invention relates to a brake system, an operating device, in particular a brake pedal, and a control and regulating device, wherein the control and regulating device controls a drive apparatus on the basis of the movement and/or position of the operating device, wherein the drive apparatus moves a piston of a piston/cylinder system, so that a pressure is set in the working chamber of the cylinder, wherein the working chamber is connected to at least one wheel brake via at least one pressure line, wherein the operating device acts on a pedal tappet and moves said pedal tappet, and the pedal tappet is connected to a travel simulator and acts on a displaceably mounted coupling element by means of a spring, wherein the pedal tappet and the coupling element are locked to one another by means of a fixing device, wherein the coupling element can be locked or fixed to and/or released or disconnected from the panel tappet by means of the fixing device optionally in any desired positions or in at least two different positions relative to said pedal tappet. | 04-15-2010 |
| 20090309447 | POLYPHASE MACHINE COMPRISING A BELL-SHAPED ROTOR - The invention relates to an electrical polyphase machine comprising an inner stator ( | 12-17-2009 |
| 20080231134 | Electric Drive Having A Bell-Shaped Armature And External Permanent Magnet Elements - The invention relates to an electric drive having a stationary outer and inner stator and a rotor, a plurality of permanent magnet elements being disposed on the rotor for producing an excitation flux and at least one electrical field coil being provided. The rotor comprises at least one bell-shaped part having a cylindrical wall and a base wall. Said base wall is mounted perpendicularly and the cylindrical wall coaxially in relation to the axis of the rotor shaft. The base wall is connected to the rotor shaft for transmitting a force or a torque. The permanent magnet elements rest on one side on the cylindrical wall and are secured side by side to the rotor of the drive in the peripheral direction. The permanent magnets, interact with the outer and inner stator, to give magnetic circuits which completely extend through the cylindrical part of the rotor in the radial direction, the permanent magnet elements being arranged only on the exterior of the cylindrical wall. | 09-25-2008 |
