摘要： Counter braking force acting on a secondary shoe is input to one end portion of a control lever supported with an anchor pin vertically provided on a backing plate in such a manner that the control lever is capable of swinging. An inner end portion in the radial direction of the control lever engages with a strut for pressing a primary shoe against a brake drum. Pressing force A with which the strut is pressing the primary shoe against the brake drum is drastically reduced when braking force, that is, the counter braking force increases and slightly reduced when the braking force, that is, the counter braking force decreases, whereby an increase or a decrease in the braking force is made automatically controllable.

摘要： A drum brake device is provided which facilitates the pre-mounting of a long link, without increasing the number of components or the cost of the device. The long link (44) is pivotable on the central segment of one brake shoe (13). An engagement hook (48) protrudes from one or the other of the long link (44) or the one brake shoe (13). A notched groove (25) is formed in the other component thereof. The engagement hook (48) is inserted into the notched groove (25). The rotation of the long link (44) relative to the one brake shoe (13) will cause the long link (44) and one brake shoe (13) to be superimposable and detachable.

摘要： An improved drum brake assembly in which brake shoes are mounted on a backing plate and coact with a rotating brake drum mounted on an axle and in which a mechanical brake adjuster has a movable component for adjusting the running clearance of the brake shoes, in which the brake drum has an adjustment access opening formed in its generally radial portion and in spaced relation to the brake backing plate. This access opening is alignable with the movable component of the brake adjuster by rotating the brake drum on the axle so as to position the access opening in opposed relation to the position of the movable component. The access opening is sized so as to provide for the insertion of a brake adjusting tool from a position adjacent the lateral side of the drum to engage the movable component, for the purpose of adjusting the shoes, and obviating the necessity of moving under the vehicle to access the movable component through the conventional access hole formed in the backing plate. The access opening is formed as an arcuately elongated slot, the long walls of which provide a convenient pry surface for the brake adjusting tool.

摘要： An automotive drum brake assembly includes first and second brake shoes mounted on a backing plate. A wheel cylinder for braking actuation is mounted between the brake shoes. An adjuster screw assembly is held between the brake shoes by an adjuster spring. The adjuster screw assembly includes a pivot nut threaded onto an adjuster screw. In one embodiment, a sleeve includes a first portion slidably mounted on the pivot nut, a second ramp portion covering the screw threads and a third portion opposite the pivot nut. The second portion, preferably formed as a frustoconical ramp, is slid by the adjuster spring to travel with the adjuster screw as it unthreads from the pivot nut, thereby shielding threads from corrosive elements.

摘要： A drum brake (10) includes a backing plate (11) supporting a pair of drum brake shoes ( 12, 14) having brake shoe webs (16, 18). An opposing pair of brake shoe ends (26, 28) have adjacent thereto a combination drum brake shoe hold-down bracket and cable guide (60) attached to the backing plate (11) . The hold-down bracket and cable guide (60) has a pair of securement portions (61) extending laterally or transversely, via axial projections (62) and ends (64) , relative to the center of revolution (A) of the drum brake (10) and which engage the drum brake shoe webs (16, 18) to assist in maintaining the brake shoes (12, 14) in operative position. Each portion (61) of the hold-down bracket and cable guide (60) extends laterally toward one another via an axially extending portion (65) that curves in an annular path to form a center portion (67) that defines a cable guide path (68). A parking brake cable assembly (40) is captured within the cable guide path (68) so that it will not interfere with other brake components. The brake shoe hold-down bracket and cable guide (60) provides a positive method for preventing the brake shoes (12, 14) from lifting off the backing plate (11) and guiding the parking brake cable assembly (40).

摘要： A brake lever for an S-cam brake has a worm wheel (3) engaging the S-cam shaft and a worm screw (4) meshing therewith. A clutch wheel (6) on the worm screw forms a clutch (8) therewith under the bias of a compression spring (9). A control movement is transmitted from an external reference point to the clutch wheel via a pinion (15), a carrier wheel (16) and a control screw (18), the common axis of these three parts being perpendicular to the worm screw, wherein the control screw meshes with the clutch wheel. The carrier wheel can be turned relative to the pinion an angular distance corresponding to the desired slack and is biassed to one end position by a torsion spring (17), which is also used to engage a one-way clutch (19) between the carrier wheel and the control screw.

摘要： A drum brake assembly includes a pair of brake shoes which are carried by a backing plate and engageable with a hydraulic actuator. The hydraulic actuator is operable to move the pair of brake shoes from a rest position to a braking position. A strut extending between the pair of brake shoes cooperates with a parking arm to move the pair of brake shoes to the braking position during a parking brake application. A support assembly on the backing plate is disposed opposite the hydraulic actuator for the purpose of absorbing braking torque developed by the pair of brake shoes. The support assembly comprises a pair of slots and a lever. The lever is movable in response to movement of the parking arm to adjust the position of the pair of blocks relative to each other. In a first position the blocks are in abutment with the backing plate while in a second position the blocks are free to move a limited amount relative to the backing plate. Moreover, the lever imparts a separating force to the pair of brake shoes via the blocks during a parking brake application to expand the brake shoes radially. This expansion is in addition to the movement imparted to the brake shoes by the strut and parking arm.
