摘要:
L'invention concerne un frein à disque dans lequel un organe de friction (18, 20) ancre et coulisse par ses extrémités circonférentielles sur un organe support de couple (10). L'organe de friction coopère par des surfaces convexes (46, 48) avec des surfaces concaves (50, 52) definies dans l'organe support, le rayon de courbure des surfaces concaves étant supérieur à celui des surfaces convexes. L'organe de friction est reçu avec un jeu circonférentiel prédéterminé dans l'organe support, et des moyens élastiques (54) maintiennent les surfaces concaves et convexes en contact tout. en sollicitant l'organe de friction en éloignement d'au moins une de des positions d'ancrage. Application au freinage des véhicules automobiles.
摘要:
A disk brake for vehicles (1), especially for utility vehicles, comprising brake shoes (6,6') on both sides of the brake disk (10) and brake linings (8), a clamping device which clamps one of the brake shoes (6), and a power transmission device to transmit clamping force to the brake shoe (6') on the other side of the disk brake. Disk brake is characterized by the fact that power transmission device is shaped like a fully enclosed frame (14), especially a rolled frame, which absorbs the clamping forces. A modular element (15) enables brake mechanism to be pre-mounted and improves structural rigidity.
摘要:
Entre l'étrier (10) chevauchant le disque de frein (2) et le support fixe (1, 3, 4) est disposé au moins un organe élastique (30) fixé à l'étrier ou au support fixe et portant en appui sur l'autre élément de façon à pouvoir se déformer élastiquement d'une quantité prédéterminée, au-delà de laquelle il est susceptible de se déplacer par rapport à l'élément auquel il n'est pas fixé, pour, dans un premier temps, exercer une force de rappel après engagement du frein tout en pouvant suivre, par glissement incrémentiel, l'usure de la garniture extérieure (8) du frein.

The disc brake caliper (11) includes a cylinder (19) and a bridge (12), the bridge having an inboard portion (13) which attaches to the cylinder, a central portion (15) and an outboard portion (14). Inboard (22) and outboard (23) friction pad assemblies are arranged to be brought into contact with opposite faces of a disc (29). The bridge (12) is formed of a resiliently flexible material and is shaped and configured such that under braking conditions the outboard portion (14) is able to resiliently deflect relative to the inboard portion (13) in a direction transverse to the axis (32) of the cylinder (19) and substantially parallel to the direction of movement of the disc (29) at the region where the friction pad assemblies (22,23) are in engagement with the faces of the disc. The bridge (12) and cylinder (19) may be separately formed and connected together or they may be integrally formed.
摘要:
The present invention comprises an integrated disc brake (50) and drum brake (120) construction. A support member (12) is supported by a vehicle axle (14) and extends radially outwardly to provide support for a housing (52) of the disc brake (50). The housing (52) is secured by bolts (93 or 94) to the support member (12), the housing (52) having through openings (54) for receiving rod members (75). The rod members (75) each have one end (76) secured to the support member (12) and a second part (90) and the other end has an opening (77) for an internal bore (78) extending therein. The disc brake (50) includes an axially movable yoke (60) attached to guide pins (82) extending into bores (78) of the rods (75) for slidable movement therein. The second part (90) extends radially to provide support for an inner brake pad (20) and may extend axially away from the housing (52) to provide an anchor support (91) for shoulders (132, 142) of drum brake shoes (130, 140). The support member (12) supports a mechanical actuator (121) which may be operated to bias the drum brake shoes (130, 140) into engagement with a drum portion (42) of the brake disc (40) in order to effect a parking brake operation.
