Patent number: 9284999Abstract: A disc brake assembly having a guide pin disposed in a bore of an anchor bracket such that a guide pin axis is offset relative to a bore axis whereby there is provided at least one defined point of contact between only a portion of the guide pin and a portion of an inner surface of the bore. The guide pin includes at least one slot having a member, which is formed separate from the guide pin, and disposed therein to bias the guide pin in the bore thereby offsetting the guide pin axis relative to the bore axis. The member includes a first member formed from an elastomeric material and a second member formed from a metal material, wherein the second member is configured to retain the member in the slot.Type: GrantFiled: March 15, 2013Date of Patent: March 15, 2016Assignees: Kelsey-Hayes Company, Lucas Automotive GmbHInventors: Kraig Gerber, Guido Zenzen

Patent number: 8905201Abstract: Vehicle disk brake designed as a service brake and as a parking- or immobilizing brake, having a brake anchor plate, which is to be fastened to the chassis of a motor vehicle by at least one screw bolt and in which two guide bolts are accommodated in order to guide a brake caliper displaceably relative to the brake anchor plate, and having a hydraulic chamber, in which a brake piston is accommodated in order to bring friction linings into and out of frictional engagement with a brake disk. A separately manipulable assembly is built onto the vehicle disk brake and has an electric motor as well as an electronic control and power device in order, independently of a hydraulic actuation of the brake piston, to actuate the brake piston via a rotary-to-linear motion converter in the sense of bringing the friction linings into and out of engagement with the brake disk.Type: GrantFiled: July 21, 2009Date of Patent: December 9, 2014Assignee: Lucas Automotive GmbHInventors: Frank Laubenthal, Dirk Hees, Guido Zenzen

Publication number: 20140151165Abstract: In a method for producing a brake carrier for a disc brake of a vehicle braking system, wherein the brake carrier has at least one guiding shaft for guiding a brake lining in a guiding direction in relation to a receiving region for a brake disc, first a brake carrier blank is produced in a casting step and then the brake carrier blank is reworked. In the casting step, the brake carrier blank forms two converging tapers, facing the receiving region, in the region in which the guiding shaft is formed and, during the reworking, material is removed in the region of the tapers to produce the at least one guiding shaft, with the effect that the receiving region for the brake disc has a predetermined clear width transversely in relation to the guiding direction.Type: ApplicationFiled: April 5, 2012Publication date: June 5, 2014Applicant: LUCAS AUTOMOTIVE GMBHInventors: Guido Zenzen, Marco Becker, Florian Rössinger, Jochen Becker

Patent number: 8517152Abstract: The invention relates to a disk brake for a motor vehicle brake system having a frame-type housing, at least two brake pad arrangements, which are accommodated in the frame-type housing and between which a brake disk that is rotatable about an axis of rotation may be accommodated, and at least two guide bolts, which are mounted on the housing and on which at least one of the brake pad arrangements is guided with play in an axially displaceable manner. To avoid undesirable noises in this disk brake it is provided that on the brake pad arrangement guided on the guide bolts at least one spring element is mounted, which biases said brake pad arrangement relative to the guide bolts into a position corresponding to a tilting movement that results during braking of the brake disk from a braking torque acting on the brake pad arrangement.Type: GrantFiled: November 16, 2009Date of Patent: August 27, 2013Assignee: Lucas Automotive GmbHInventors: Guido Zenzen, Marco Becker, Michael Schog, Florian Rössinger

Patent number: 7431132Abstract: A disc brake comprises a brake carrier, which is fastenable to the vehicle and is provided with bolts at the leading side and at the trailing side of the brake, which during braking take up the forces acting upon the brake linings. The relative dimensions and arrangements of the bolts and of the brake lining are such that, upon introduction of a brake force that is capable of decelerating the vehicle up to a maximum value in the region of 0.1 g, only tensile forces act upon the brake lining.Type: GrantFiled: September 19, 2005Date of Patent: October 7, 2008Assignee: Lucas Automotive GmbHInventors: Michael Schog, Karl-Heinz Wollenweber, Christian Schroeter, Dirk Hees, Guido Zenzen

Patent number: 6394235Abstract: A hydraulic vehicle brake (10) has a hydraulic chamber (16) which sealingly accommodates a brake piston (18) which can slide along an axis (A). The brake piston (18) acts upon a friction member and can be moved by means of hydraulic pressure which is supplied to the hydraulic chamber (16) into an actuating position in which it presses the friction member against a rotor (brake disk, brake drum, etc.). In order to be able to use the vehicle brake (10) besides its function as a hydraulic service brake also as a parking brake, a spindle/nut arrangement (24) is provided which is driven by an electric motor (42) and arranged coaxial to the axis (A) of the brake piston (18), the nut (30) of which arrangement (24) is secured against rotation, and by rotation of the spindle (26) as a function of the sense of rotation can either be moved into contact with the brake piston (18) or be moved away from the brake piston (18) translatorily along the axis (A).Type: GrantFiled: January 21, 2000Date of Patent: May 28, 2002Assignee: Lucas Industries plcInventors: Gregor Poertzgen, Karl Friedrich Wörsdorfer, Ralf Erben, Guido Zenzen
