Abstract: The strut, mounted in the vicinity of the brake application mechanism and bearing with each of its ends against each of the shoes (3, 4), has a device which automatially extends according to the wear of the friction components and which consists of a nut-and-bolt system (8-11) operated by a pawl (12) engaging with teeth (11) integral with the nut. The pawl (12) is mounted on an elastic leaf (13) integral with the strut and separated elastically therefrom by a rocker lever (14) which, by tilting, allows the leaf (13) to move toward the strut when the shoes are pushed apart, thus enabling the pawl (12) to cause the nut (11) to rotate and, therefore, the length of the strut to increase. A bimetallic strip (30) is capable of counteracting the tilting movement of the lever (14) when the brake is hot.

Abstract: The invention relates to spring (40) for a disc brake. The spring is mounted elastically in an opening (68) of a caliper and exerts on the support plates (26, 28) a radial force (F1) as well as a tangential force (F'5) ensuring that the plates assume a preferred lateral position. The spring (40) comprises a metal leaf with two main arms (42, 44) connected to each other and to a central arm (48) by a main fold (46), the spring having the general shape of a "trident", the end prongs of which comprise the main arms (42, 44), the latter cooperating by way of their free ends (50) with a surface (52) formed on the caliper (10) and by way of central portions (54) with bearing surfaces (56) formed on the support plates, the central arm (48) having at its free end (62) a Z-shaped fold cooperating with two surfaces (64, 66) of the caliper, the main fold (46) having a lug (74) cooperating radially with another surface (76) of the caliper (10).

Of the ends (46, 54) of the central portion (34), one end (46) incorporates an extension (44) which enters with a predetermined radial clearance into a hole (48) formed facing it in the calliper (10).

According to the invention, the caliper (18) has two openings (54, 56), the first opening (54) receiving the rear arm and the corresponding pins (14) and permitting the radial extraction of the friction elements (36, 38), and the second opening (56) receiving the front arm (26) and the corresponding pins (16).

Abstract: The invention relates to a multi-disc brake comprising a stationary rotary disc (1) and a moveable rotary disc (2) which is mounted on a splined sleeve (5) sliding on a splined part (3a) of a hub (3) of axis (4) and with which the disc (1) is solid. An assembly of friction pads (6 to 9) can interact with the discs (1,2) under the action of a hydraulic jack (13). The splines (23,25) of the hub and of the sleeve are protected from dirt by deformable diaphragms (20,26) which are turned in on themselves and which are arranged so as to be shielded from the thermal radiation emitted by the braking members (1,2,6 to 9).

Abstract: The subject of the invention is a disc brake of the type with a caliper (1) mounted to slide on a fixed support (4) by a column (3). The caliper (1) incorporates a brake motor (9) acting directly on an inner pad and via the caliper (1) on an outer pad. The two pads are received so as to slide in an orifice (5) formed in the caliper (1). The pads are locked in the orifice by a key (20). According to the invention, the inner pad incorporates a semi-circular lug (25) mounted in a semi-circular receptacle (24) formed in the fixed support (4) so as to prevent the caliper (1) from tilting about the column (3) when the pads are in place and are locked by the key (20). The invention may be utilized with the brakes of motor vehicles.

Abstract: The invention relates to a multi-disc brake comprising a stationary rotary disc (1) and a movable rotary disc (2) which is mounted on a splined sleeve (5) sliding on the hub (3) of axis (14) and with which the disc (1) is solid. An assembly of friction pads (6-9) can interact with the discs (1, 2) under the action of a hydraulic jack (13). To prevent any rattling at the start of each braking operation, elastic blocks (50) are inserted inside housings provided in the system of splines of the sleeve (5) and of the hub (3) and, when expanded, draw the flanks of the splines against one another in working contact during a braking operation.

Abstract: The subject of the invention is a disc brake of the type with a caliper (14) mounted so as to slide on a fixed support (2) by means of a pin (15). The caliper (14) incorporates a brake actuator acting directly on a friction pad (12) and, through the sliding caliper (14), upon the other pad (13). The pads (12, 13) are guided at least partially by transverse housings (7, 8) in the fixed support (2). According to the invention, the single pin (15) is positioned opposite the rear end portion of the inner friction pad (12), viewed in the direction of foward motion, in such a way that the orthogonal projection of the pin (15) onto the brake disc (6) is at least partially on the path of the latter, and viewed in the direction of motion slightly downstream of the corresponding guide housing (8) formed in the fixed support (2). Applicable to the braking systems of motor vehicles.

The device (10) is made in a single piece from a sheet of stainless spring steel.

Abstract: The brake comprises two shoes lined with friction elements stressed by a clamping mechanism located between two first ends of the shoes, a fixed anchoring block located between the other two ends of the shoes, and a spacer (44) mounted in the vicinity of the clamping mechanism and bearing by each of its ends on each of the shoes.

Abstract: In a disc brake of the type in which at least one fluid pressure actuated piston is associated with a caliper to urge a first friction element directly onto a first friction face of the disc, the caliper being slidable by way of at least one column on a torque-taking member to urge by reaction a second friction element on to the other side of the disc, a locking connection is provided between the second friction element and the column to immobilize the column with respect to the caliper through a removable support connection provided between the second friction element and the caliper. The locking connection is preferably comprised of at least one extension of the backing plate of the second friction element, this extension being designed to fit into a corresponding slot in the at least one column.

Abstract: The invention relates to a mechanical control device for a disc brake. The mechanical control device comprises two members 28, 32, 128, 132 extensible in an axial direction with respect to the brake disc upon relative rotation therebetween. These members are respectively connected to a control member 34, 134 and to a piston 20, 120 associated with a friction member 22, 122. Adjusting means 56, 156 comprise an annular element 58, 158 cooperating by way of one-way toothings 60, 62 with the member 28, 128 connected to the control member in order to turn relative to member 28, 128 upon brake actuation, when the wear of the friction member 22, 122 is greater than a predetermined value. Upon return of the control member 34, 134 to its idle position, a friction spring 48, 148 inserted between the piston 20, 120 and the member 28, 128 permits this member 28, 128 to turn relative to member 32, 132, thus adjusting for the wear of friction member 22, 122.
