摘要:
A disk brake having a caliper (1) which straddles a disk (2), a carrier (3) fixed to the vehicle, a cylinder (4) secured to the caliper and closed by a piston (5) and two friction pads (10,11). Two cylindrical and mutually parallel guide pins which slide in corresponding housings. These housings being partially formed by bores (8, 9) made in the carrier (3) for maintaining the caliper (1) with the cylinder (4). The first bore (8), over first and second contiguous sections (s1, S2) of its length, has first and second respective inside diameters (D1, D2), the second diameter (D2) of which is greater than the first diameter (D1). The smaller diameter (D1) being formed on the same side of the first housing as the opening of the bore (8) and the first housing is formed, in addition to the first bore (8), from inside (130) a ring (13) made of elastomeric material.

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.
摘要:
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.
摘要:
A disk brake for a motor vehicle having a caliper (10) and a support (40) which slide with respect to each other to move first (17) and second (20) friction pads into engagement with a disk (30) to effect a brake application. A guide arrangement which allows the caliper (10) to slide with respect to the carrier (40) has a first guide tube (49) connected to the support (40) with a first bore (53) located at right angles to the disk (30) and an external surface (55) which slideable accomodates a first end of each of the first and second friction pads (17,20).
摘要:
A drum brake having a support plate (10) with first and second shoes (12,14) slidably mounted thereon. Each of the shoes (12,14) having a web (12a,14a) and a rim (12b,14b) with a face for receiving a friction lining (16,18). Each web (12a,14a) has a first end and a second end. The rim holds the friction lining in a position to engage a drum (20) in response to an input force applied to the first end of the webs (12a,14a) of the shoes (12,14) by a hydraulic actuation device (22). A bearing member (28) is secured to the support plate (10) and is connected to a second end of the webs (12a,14a). A spacer device (40) arranged in the vicinity of the hydraulic device has a variable length to establish a spacing between the shoes (12,14) and drum (20). A mechanical actuation device (50) secured to a web (14a) of shoe (14) has a first actuation lever (60) and a second lever (70). A force applied to the first lever (60) is articulated through the second lever to act on the web (12a) of shoe (12) such that a brake force is substantially distributed to bring each friction lining (16,18) into engagement with the drum (20) and effect a brake application.
摘要:
A disc brake comprises a caliper mounted slideably relative to the axis of the rotating disc, on a fixed support by way of an axial column, two friction members mounted on carrier plates anchored and axially slideable inside an opening in the fixed support so as to come into frictional engagement with the opposing sides of the disc when a brake motor is operated, and a locking element extending axially between at least one opening formed in the caliper and at least one opening formed in the fixed support so as to help guide the caliper on the fixed support and prevent it pivoting about the column when it assumes its normal operating position. A spring is mounted on the caliper on the side located circumferentially at a distance from the axial column, the mounting portion being elastically mounted inside at least one opening provided in the caliper for the locking element to pass through, the mounting portion surrounding substantially the part of the locking element passing through said opening, the rigid working portion being capable of biasing elastically the friction-member carrier plates substantially radially towards the axis of the disc.
摘要:
Multiple disc brake comprising a first rotary disc fixed to a hub connected to a rotating member to be braked and at least one second rotary disc capable of sliding axially relative to the hub and to the first disc. A first axial guide sleeve (16) fixed to the first disc (1) is arranged coaxially relative to a second axial guide sleeve (18) fixed to the second disc (2) and is connected to this second sleeve (18) by way of several grooves (22), rolling members (27) being in contact with at least one face of these. The invention is used on multiple disc brakes for land vehicles.
摘要:
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.
摘要:
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.
