Abstract:
The invention relates to anticorrosive paint for producing an anticorrosive coating, one such coating, and a method for removing the anticorrosive coating. In order to remove the coating in a more favourable manner while simultaneously ensuring protection against corrosion, the anticorrosive paint, and thus the anticorrosive coating produced therefrom, comprise protective substances which react with oxygen. The anticorrosive coating is rubbed off by the abrasive effect of the brake linings during braking, while the protective substances of the anticorrosive coating are rubbed into the brake surface.
Abstract:
Arrangement for releasable fastening of an annular brake disc (2) to a rotatable brake disc carrier (4), such as a wheel hub, which supports a brake disc, whereby the brake disc's internal periphery is provided with driving protrusions (6) which are separated in the circumferential direction, face radially inwards towards the centre (C) of the disc and engage in a corresponding number of external axial grooves (8) between ridges (10) which run axially on the outside of the carrier (4). The extent of the driving protrusions (6) is smaller than the width of the grooves (8) in the circumferential direction of the carrier so that between adjacent sets of mutually engaging driving protrusions and grooves a spacing gap (12) may be formed to accommodate a spacing device (14) fastened removably therein which fits into and fills the spacing gap and hence fixes the brake disc (2) relative to the carrier (4). The spacing device (14) is provided at its axially opposite ends with shoulder portions (18, 20) which prevent mutual axial movement between the brake disc and the carrier.
Abstract:
A disc brake (10) of the kind comprising an axially fixed hub (15) and at least one slidable brake disc (12, 14) comprises resilient means (26) acting between the disc (12, 14) and the hub (15) to control certain aspects of the movement of the brake disc (12, 14) during use. Despite the thermal differential (A) arising in use between the brake disc (12, 14) and the central hub (15) due to the localised heat generation (E) of the spot-type automotive brake (10) and the mass and thermal capacity differences between the hub (15) and the brake disc (12, 14), whereby the hub would be expected to provide a more satisfactory mounting, resilient means (26) acting between the disc (12, 14) and the hub to control the disc dynamics is mounted on the disc (12, 14), this leading to advantages in terms of independence of the resilient bias with respect to disc position and disc (12, 14) relationship to another disc (if present) and with respect to simplicity of mounting and avoidance of dirt entrapment.
Abstract:
A vehicle wheel brake system (9) for a wheel suspension assembly has an anti-lock braking system ("ABS") to provide a higher resolution brake apply and brake release relative to an ABS system having a single, fixed brake disc. The brake system comprises a mounting hub (14) for a road wheel mounted on the wheel suspension assembly for rotation about a rotational axis. At least two slidable brake discs (38, 41) are mounted to slide axially along the hub between braking and off-brake positions and provide signals when the wheel condition is within preset parameters relative to the speed of the vehicle. A brake actuator system is operable manually and is operable automatically by the ABS controller to operate the caliper and a frequency of brake apply and with release of at least double the frequency of brake apply and release of a fixedsingle brake disc system.
Abstract:
The invention relates to a method for producing brake disks with friction surfaces consisting of ceramic materials, especially composite materials. At least one ceramic part is placed in a diecasting mould and is joined to molten metals by casting under pressure, in order to obtain a rotationally symmetrical body. Said body contains at least one ceramic (composite) segment that is symmetrical to the axis of rotation of the metal body and projects beyond at least one surface of the metal body that is perpendicular to said axis.
Abstract:
The invention relates to a bainitically hardened brake disk comprising at least one ring-shaped cast disk (1) body with radially extending ring sections in contact with brake shoes (2). Said brake disk is mounted on the hub of a bicycle wheel (5) for braking purposes. In order to avoid noise emissions and vibrations, the inventive disk is made of cast iron, is highly tough and has a low weight. The aim is to avoid the disadvantages of combining disk brakes with an aluminium wheel hub. The inventive disk is characterised in that it has a thoroughly bainitically hardened body (1) made of cast iron with lamellar graphite (AGI), the brake disk is designed as a single piece and is linked to the wheel hub (5) through composite casting by forming a positive material fitting joint (15) in the area where the hub (5) is connected to the base (3) of the disk.
Abstract:
The invention relates to a braking device for the wheels of a motor vehicle, comprising a brake drum (1) on the side of the wheel and a dirt collector plate (2) on the side of the vehicle, which engages with a peripheral rib (3) in a ring-shaped cavity (4) in the front face (5) of the brake drum (1) opposite the dirt collector plate (5) without any contact to form a maze-like seal. In conventional brake systems the dirt collector plate is usually made of two parts with a welded ring-shaped rib. According to the invention, the dirt collector plate (2) is produced from a steel sheet section by means of stamping and deep-drawing and the peripheral rib (3) is formed by non-cutting shaping with the dirt collector plate in a single piece.

Abstract:
A brake rotor (10) includes a radially hat section (12) having a central mounting face (14) for mounting the rotor (10) with an outer friction portion (30) extending from the cylindrical hat wall (16). The outer friction portion includes a pair of opposite, flat annular friction rings (52, 54) adapted to interface with associated friction members. The outer friction portion of the rotor further includes a core (40) extending radially outwardly from the cylindrical hat wall (16) of the hat section (12). A layer of a sound dampening material (48, 50) is secured between the pair of outer friction ring sections (32, 34) and the core. The rotor (10) of the invention transmits less noise than conventional rotors.
Abstract:
A rotor (10) for caliper disc brakes and the like has an outer friction portion including an annular support plate (32) having a friction ring section on both of the major surfaces thereof adapted to interface with an associated friction member, such as a brake pad. Each of the friction ring sections is formed of a plurality of circumferentially spaced apart fins (42, 44). Each of the fins, (42, 44) includes a substantially flat friction surface (42a), so that the plurality of such surfaces (42a) combine to define an annular, non-continuous friction surface on each face of the support plate (32). The rotor (10) of the invention combines the strength of a solid rotor with the desirable increased cooling characteristics of a vented rotor.
