20080251310 | Vehicle Steering System - A vehicle steering system for motor vehicles has a steering handle operable by the driver and connected to steerable vehicle wheels in terms of effect to determine a direction of driving. The vehicle steering system includes a hydraulic working cylinder having two directions of effect, as well as a hydraulic pressure source, which applies hydraulic pressure to a valve assembly. The valve assembly controls the magnitude of the hydraulic pressure conveyed to the working cylinder and determines the direction of effect of the working cylinder. The valve assembly has two separated valves, the first valve determining the direction of effect of the working cylinder, while the second valve controls the working pressure for the hydraulic working cylinder. | 10-16-2008 |
20090008199 | Motorcycle Brake System - A hydraulic motorcycle brake system includes an accommodating member for the hydraulic connection of two master brake cylinders to the front-wheel brake and rear-wheel brake having several pressure channels for the front-wheel circuit and rear-wheel brake circuit, and allowing manufacture in a simplest possible manner, and a pair of wheel brake connections connectable to the rear-wheel brake and front-wheel brake open into a lateral surface of the accommodating member, the wheel brake connections being arranged between a pair of pressure connections that are connectable to the two master brake cylinders. | 01-08-2009 |
20090039701 | Motorcycle Brake System - A hydraulic motorcycle brake system whose brake circuits are provided with a valve circuit which prevents the pressure which can be generated by the pump from reacting on the manually activated or foot-activated master brake cylinder. | 02-12-2009 |
20090184567 | Motorcycle Braking System - A hydraulic motorcycle braking system is disclosed. In the hydraulic motorcycle braking system a pump suction valve, which is situated in a braking circuit that does not contain an isolating valve or a change-over valve, has a higher opening pressure than a pump suction valve which is situated in a braking circuit provided with an isolating valve and a change-over valve. Accordingly, pressure oscillations initiated during the start-up of the pump cannot have a retroactive effect or only have a slight retroactive effect on the actuated brake master cylinder. | 07-23-2009 |
20090250923 | Unit With At Least Two Hydraulic Connections Fastened To It - 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. | 10-08-2009 |

20090295221 | Hydraulic Trailer Brake System - 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. | 12-03-2009 |
20100117448 | BRAKING SYSTEM FOR MOTOR VEHICLES - In order to embody an electrohydraulic brake system of the brake-by-wire type in a way which is optimized in terms of installation space, it is proposed that a booster device for boosting the activation force which is transmitted to a pressure sensor by the brake pedal is composed of a booster module, which is connected upstream of the pressure sensor, and of a hydraulic pressure source, and in that the pressure sensor forms, with the booster module, a first functionally capable assembly which can be handled independently, and a pressure source, an electronic open-loop and closed-loop control unit and a valve block which accommodates the pressure control valves form a second functionally capable assembly which can be handled independently and which is arranged spatially separate from the first assembly. | 05-13-2010 |
20100202908 | SUPPLY DEVICE - A supply device for the supply of pressure fluid into at least one vehicle brake or into a pressure fluid accumulator, wherein a piston is movably arranged in an accommodating member, a carrier bears a non-return valve arranged coaxially to the piston for the purpose of ventilating a working chamber into which the piston plunges, and wherein a resetting spring is arranged between the carrier and the piston. A multi-piece cage facilitating inserting the resetting spring into the cage parts, the cage parts comprise fastening means that lock the cage due to relative displacement of the cage parts, and the resetting spring is caged and simultaneously elastically preloaded under the relative displacement of the cage parts. | 08-12-2010 |
