20090026985 | Method for Actuating an Electromagnetic Valve - A method for is provided actuating at least one electromagnetic valve containing at least one coil, which can be excited by an excitation current, and an armature, in which the excitation current can be set such that, in response to a signal for actuating the armature from one position into another position, it causes the actuator to move as a result of an excitation current threshold being exceeded, and is kept at a value which is lower by comparison in order to hold the armature in a specific position. The excitation current, which is greater than zero but below the excitation current threshold, is applied at least temporarily to the electromagnetic valve even if no signal for actuating or for holding the armature is present. | 01-29-2009 |
20090020375 | Disc Brake for a Commercial Vehicle - A commercial vehicle disc brake has a caliper that straddles a brake disc that can be functionally connected to brake pads having a brake lining supporting plate and a friction lining secured thereto. At least one closure cover encloses and hermetically seals a chamber for housing functional parts of the brake. The disc brake is designed such that the closure cover is form-fittingly connected to the brake caliper. | 01-22-2009 |
20090014262 | Disc Brake and Brake Pad for a Commercial Vehicle - A disc brake for a commercial vehicle includes a caliper which, in use, straddles a brake disc. A closure cover closes-off an opening of the caliper. A brake pad includes a lining carrier plate and a friction lining material fastened thereon. The closure cover and the lining carrier plate have a respective elevation and recess which correspond to each other in a coded manner. | 01-15-2009 |
20090000881 | Disc Brake for a Commercial Vehicle - A disc brake is provided for a commercial vehicle, having a brake caliper and brake pads, which make contact with a brake disc. At least one brake pad, together with a carrier plate and a friction lining fixed on the latter, can be pressed against the brake disc by a brake application device via at least one rotatable control spindle and a pressure piece which is operatively connected to the latter and is connected fixedly to the carrier plate. A folding bellows, which is fastened such that it cannot rotate to the brake caliper and bears freely for the unimpeded rotation of the control spindle and yet in a sealing manner against said control spindle, is provided for sealing the outlet region of the control spindle out of the brake caliper. | 01-01-2009 |
20080309154 | Method For Controlling a Pneumatic Braking System - A method for controlling a pneumatic braking system of a utility vehicle that includes a service brake and an electric parking brake, an electronic control unit being provided for controlling the electric parking brake. The parking brake assists a brake intervention of the utility vehicle when there is a circuit failure of the service brake. | 12-18-2008 |
20080289914 | Disk Brake, in Particular for a Commercial Vehicle - A disc brake, particularly for a utility vehicle, includes a caliper that is fastened to a brake support and is provided with a receiving chamber for a clamping mechanism, as well as a brake disc which can be effectively connected to brake pads. The disc brake includes a retaining clip, which is removably fastened to the caliper while supporting springs that act upon the outer edge of the brake pads. One end of the retaining clip positively lies in a receptacle of the caliper while the other end thereof is retained by a fastening element. The fastening element has two limbs, which are secured in holes provided in the caliper on both sides next to the retaining clip. | 11-27-2008 |
20080284241 | Combined Service Brake and Spring-Loaded Brake Cylinder with Internal Ventilation - A combined service brake and spring-loaded brake cylinder includes an air-bleed valve having a piston supporting a valve body, which is guided inside a cylinder in an axially displaceable manner, and at least one first pressure spring supported on the piston being loaded against a first valve seat on the piston. The piston is loaded by at least one second pressure spring which is supported on the piston rod, in such a manner that the valve body is pushed toward a second valve seat on the piston rod and away from the first valve seat. A first piston area of the piston is loaded by the pressure in the spring chamber in a direction that lifts the valve body from the second valve seat and a second piston area by the pressure inside the service brake chamber in a direction that pushes the valve body toward the second valve seat and lifts it from the first valve seat, whereby a flow connection is established between the service brake chamber and the spring chamber by the valve seat and/or when the valve seat is lifted from the second valve seat. | 11-20-2008 |
20080283685 | System and Method for Externally Fastening Cables or Lines to a Brake Cylinder - A fastening device for externally fastening cables or lines to housings, especially to the housing of brake cylinders, includes a fastening pin that can be locked in a breather of the housing. A connecting channel is configured in the fastening pin via which channel, in the locked state, the interior of the housing communicates with the atmosphere. | 11-20-2008 |
20080277215 | Holding Device for the Brake Linings of a Disk Brake and Associated Brake Lining - A brake lining for a disc brake of a road vehicle has a blade-type retaining spring for the lining. At least two peripheral lining springs are situated on each brake lining, adjacent to the retaining spring, and exert a compressive force on at least some sections of the periphery of the lining carrier. The springs are configured in such a way that they respectively cover an edge region of the brake lining carrier, with the latter having at least two corner regions. | 11-13-2008 |
