Patent number: 7731004Abstract: The invention relates to a brake lining (1) comprising a lining support plate (2) which is provided with a friction lining (7) arranged on the surface thereof. A damper plate (3) is placed on the opposite to the friction lining (7) second face of the lining support plate (2). Said damper plate (3) comprises integrated anchoring elements (4) for preventing lateral sliding thereof, wherein said anchoring elements (4) pass through a recess embodied in the lining support plate (2) and are engaged with the friction lining (7). Damping layer (6) on which a brake piston can act during braking is disposed on the damper plate (3) opposite to the lining support plate (2). An adhesive layer (8) is applied between the damper plate (3) and the lining support plate (2) in such a way that the damper plate (3) is fixable to the lining support plate (2).Type: GrantFiled: October 18, 2005Date of Patent: June 8, 2010Assignee: TMD Friction GmbHInventor: Willmut Roehling

Patent number: 7728259Abstract: A brake lining comprises a lining support plate, an underlayer material and a friction lining. The brake lining is clamped between a pressure plate and a holding fixture, which forms a hole matrix and inside of which electrodes are accommodated. A power supply is connected to the electrodes. The adjacent electrodes have different polarities. A current flow is produced between adjacent electrodes as a result of the different polarities. The field lines extend in the shape of an arch. An arrangement of this type permits the friction lining to be scorched. For hardening, a potential gradient can also be applied between the electrodes and the support plate. The current then flows and the entire friction lining is permeated. This results in a homogenous heating of the friction lining. The invention enables an efficient hardening of the friction lining. It is also possible to conduct a hardening and scorching simultaneously. The invention also enables the friction lining to be pressed during the heat treatment.Type: GrantFiled: September 12, 2002Date of Patent: June 1, 2010Assignee: TMD Friction GmbHInventor: Wolfgang Hogenkamp

Patent number: 6481544Abstract: A disk brake and brake pad set that includes a brake disk (2) and two brake pads (4, 6) wherein each brake pad (4, 6) has a carrier plate (8) and a friction lining layer (10, 12) arranged on the carrier plate (8). Each friction lining layer (10, 12) has a central area (22) of identical layer thickness,an area (14, 16; 18, 20) of reduced layer thickness at at least one end of the brake pad (4, 6),and a separating line (24) that defines an edge between the central area (22) and the at least one area (14, 16; 18, 20) of reduced layer thickness. When the two brake pads (4, 6) are arranged opposite each other on either side of the brake disk (2) the areas (14, 16; 18, 20) of reduced layer thickness of the friction lining layers (10, 12) are tangential to the brake disk (2) and the areas (14, 16; 18, 20) of reduced layer thickness of the friction lining layers (10, 12) and the separating lines (24) are arranged asymmetrically relative to each other.Type: GrantFiled: October 21, 1999Date of Patent: November 19, 2002Assignee: TMD Friction GmbHInventors: Joerg-Dieter Brecht, Karl-Heinz Oehl
