Patent number: 10962072Abstract: A friction lining for a brake pad of a braking system includes a solid body of friction material having plurality of slots intersecting at a vortex zone formed as a circular recess in the friction lining. The slots open into the vortex zone at offset locations to promote circulation of air within the vortex zone. The slots extend along a horizontal arc that follows the curvature of a rotor of the braking system when in use. Vertical slots may be included that also open into the vortex zone at offset locations.Type: GrantFiled: December 14, 2016Date of Patent: March 30, 2021Assignee: Federal-Mogul Motorparts LLCInventors: David Douglas Muffley, David Thornton Pindar, Daniel Evan Berard, Kazuhiko Isono

Patent number: 8800728Abstract: A heavy-duty vehicle brake assembly with a sealing interface includes a brake shoe, which includes a shoe table mounted on a web and a brake lining mounted on the shoe table. The shoe table is coated with a zinc-rich coating to form the sealing interface between the brake lining and the shoe table. The sealing interface resists the formation of corrosion cells on the brake shoe table, which in turn reduces the build-up of significant rust between the brake shoe table and the brake shoe lining, thereby preventing cracking and potential dislodging of the lining, while also facilitating replacement of linings when they eventually wear. A method of constructing a heavy-duty vehicle brake assembly with a sealing interface is also provided.Type: GrantFiled: March 9, 2012Date of Patent: August 12, 2014Assignee: Hendrickson USA, L.L.C.Inventor: Dhawal Dharaiya

Publication number: 20130213750Abstract: A brake system of an elevator, an escalator or a moving walkway includes a brake device with at least one brake shoe. The brake shoe has an effective surface which during brake use is pressed against a friction surface, which is moving or movable relative to the effective surface, of a counter-member. The brake system also includes a feed device which is supplied by a fluid source. A fluid can be fed between the effective surface of the brake shoe and the friction surface, which faces it, by means of the feed device. The friction between the effective surface and the friction surface can be influenced by the feed of the fluid.Type: ApplicationFiled: February 15, 2013Publication date: August 22, 2013Applicant: INVENTIO AGInventor: INVENTIO AG

Publication number: 20110024244Abstract: A brake lining, particularly for a commercial vehicle disc brake, and an associated adapter (5, 6), and a disc brake having said brake lining and the adapter (5, 6) for commercial vehicles have a carrier plate (1) with a friction lining (2) disposed thereon and at least one force application region (3, 4) on the side thereof facing away from the friction lining (2). An adapter (5, 6) is in a contact position with the force application region (3, 4) in the operating position of the brake. The adapter, in turn, is in working contact with a brake plunger or a brake piston. In order to fix the adapter (5, 6) and the carrier plate (1) at least in the radial direction (11) and circumferential direction (12), mounting means (7, 8) are provided on the carrier plate (1), with corresponding mounting means (9, 10) provided on the adapter. The adapter (5, 6) is thereby simply disposed on the force application regions of the carrier plate (1) and releaseably connected thereto.Type: ApplicationFiled: February 25, 2009Publication date: February 3, 2011Applicant: TMD Friction Services GmbHInventor: Willmut Roehling

Patent number: 7377368Abstract: A disc brake has a brake carrier (10) with at least two bolts (16a, 16b, 18a, 18b) which stand axially to the brake disc for guiding a brake lining (32a, 32b). The plane (P) spanned by the bolt axes has a smaller radial distance (D) from the disc axis (A) than the centroid of the friction lining.Type: GrantFiled: September 19, 2005Date of Patent: May 27, 2008Assignee: Lucas Automotive GmbHInventors: Michael Schog, Karl-Heinz Wollenweber, Christian Schroeter, Dirk Hees, Guido Zenzen

Patent number: 7275625Abstract: A disk brake pad controls rotation of a disk rotor by pushing a friction surface against the disk rotor while it is rotating. The disk brake pad is formed with respective chamfered portions at respective end portions of the disk brake pad at the incoming and outgoing disk-rotor-rotation sides thereof. An edge of an end portion of the friction surface of the disk brake pad at the incoming disk-rotor-rotation side, and an edge of an end portion at the outgoing disk-rotor-rotation side are formed in a stepped bending shape such that a length of the friction surface in a circumferential direction of the disk rotor becomes shorter in a center of rotation direction of the disk rotor.Type: GrantFiled: July 22, 2004Date of Patent: October 2, 2007Assignee: Advics Co., Ltd.Inventors: Nobuyuki Oi, Katsuaki Ishii, Yuichi Takeo

Patent number: 4031988Abstract: One or both ends of a skateboard has its effective lower surface of the platform brought nearer to the ground than the remainder of the platform by the addition of a block or blocks which comes into contact with the ground when the rider elects to ride the skateboard on only one of the two sets of wheels. The existence and shaping of this block assists the rider to maneuver and control the board and avoids the wear of an irreplaceable part of the board. The block is moulded plate of suitable material attached to the underside of the board the major opposing sides of the plate being elliptical. For control purposes the shape over a 120.degree. central sector of the major side is significant but for wear factor reasons it is extended to 160.degree.. No part of the radius should be less than 15 mm, or more than 110 mm. and the contact periphery should have a rounded shoulder to provide a satisfactory area of initial contact.Type: GrantFiled: April 28, 1976Date of Patent: June 28, 1977Inventor: David John Hill
