Abstract: A drum brake has a pair of brake shoes (40) moveable radially outwardly into contact with an associated brake drum to provide a handbrake function by a cross strut (100) which acts between the brake shoes or between pivoting brake operating levers (14) which actuate the brake shoes. A handbrake lever (18) is pivoted on one brake shoe or brake operating lever (14) and contacts one end of the strut to displace the other brake shoe or brake operating lever towards the drum to apply the associated shoe against the drum and by reaction through the strut to also force the other brake shoe or brake operating lever toward the drum to apply the other shoe against the drum. The strut (100) is in two parts (101,102), one part being connected for movement with each respective brake shoe or operating lever, the strut parts having inter-engageable formations in the form of teeth (103,104) which when engaged allow the strut (100) to transmit axial force between the shoes or operating levers.

Abstract: The present invention concerns a sensor system for monitoring at least the wear of lining material of a disc brake. It may also be used to monitor the stroke of the brake actuator. The sensor system receives signals from a first external and/or internal means and a second sensor means indicative of at least two different conditions of the brake. The major part of the sensor system is received on a cap to be fixed to the caliper and giving a measuring reference. The first means monitors the occurrence of a brake movement. The second sensor means monitors the actual position of a part indicating the wear of the brake lining material and/or the stroke of the brake actuator.

A release mechanism is associated with the brake arm, and is positioned about the pivot. A self adjusting mechanism is associated with the brake arm and release cable. The self adjusting mechanism is positioned about the pivot.

Abstract: A park brake includes a brake lever that is movable about a pivot. A release mechanism is associated with the brake lever and includes a pawl adapted to contact and lock with a sector. A trigger is linked with the pawl and is moveable to change a moment of the pawl relative to the sector allowing selective movement of the brake lever.

Abstract: An automatic clearance adjusting device 10 that automatically adjusts the position of brake shoes (3, 4) based on the wear includes an adjuster gear that is rotatably depending on the amount of how much the brake shoes are parted from each other, a cam plate (25) rotated integrally with the adjuster gear (23) to drive the strut (27) that restricts the position of the brake shoes (3, 4), and an adjuster restricting lever (33) that restricts the rotation of the adjuster gear (23) based on the pressing force from the wheel cylinder (6) that parts between the pair of brake shoes (3, 4).

Abstract: This dual mode drum brake provides less stroke loss during the brake operation; a stable parking brake effectiveness; and a comfortable feeling for the operator during the brake operation. A wheel cylinder actuator (15) is positioned between ends (11d) and (12d) of first and second brake shoes (11), (12); an anchor block (16) is positioned between the other ends (11e) and (12e); a shoe clearance adjustment device (18) is extended adjacent to the wheel cylinder actuator (15); a parking brake actuator (23) is extended adjacent to the anchor block (16); a bent portion (22c), formed on one side (22b) of a pivot lever (22) pivotally supported on the first brake shoe (11), is inserted between the first brake shoe (11) and the shoe clearance adjustment device (18) while the other side (22d) of the pivot lever (22) functionally engages with the parking brake actuator (23).

Abstract: An adjuster strut (10) for use in a drum brake assembly. The adjuster strut (10) has an adjustable elongate extent with first and second engagement means (17,37) disposed at opposite ends thereof for engaging opposed braking members (11,12,35) of a brake assembly. The first engagement means (17) is arranged for receipt and support within an inwardly opening slot (19,20) formed in one of the braking members (11,12,35) and includes an end face (18) for abutting engagement with the inner end wall (19a,20a) of the slot opening (19,20). The first engagement means (17) further includes a first channel (21) extending rearwardly from the face (18), for receiving therein an edge or wall portion (hereinafter an “edge portion”) defining the slot opening (19,20). The braking members can include opposed cross-sectionally T-shaped brake shoes and a parking brake lever disposed adjacent the inwardly extending web of one of the brake shoes.

Abstract: An adjuster mechanism in a drum brake wherein a rotation of a star wheel on a shaft of an extendable strut is limited to a single increment define the pitch of a plurality of teeth on the star wheel. The limitation is achieved by a lever that is carried by a web of a brake shoe has a first blade that in perpendicular alignment with a first tooth of the plurality of teeth while a second blade is offset from a second tooth and located in a plane that is substantially parallel with the pitch. When the lever is pivoted on the web through a predetermined angle, the first blade slides into engagement with a third tooth while the second blade moves through the offset and into engagement with the second tooth to connect the lever with the star wheel. Any further pivoting of the lever by movement of the web toward the drum results in the lever and star wheel moving together.

Abstract: It is an object of this invention to provide an automatic shoe clearance adjustment device for a drum brake mechanism designed to improve its durability by eliminating a gap, which is caused due to the manufacturing tolerances between the operating end surface of a brake shoe and the extended portion of an adjustment lever. To that end, a long hole (81) is formed to extend horizontally in the actuating direction of a service brake actuator (50); and the adjustment lever (80) is pivotally supported via a pin (14) with a capacity of making a rotation relative to the brake shoe (20) and a capacity of making a relative slide in approximately the same direction in which the service brake actuator (50) operates.

Abstract: It is an object of this invention to provide a drum brake device which solves a problem of decreasing the strength of a back plate near an anchor block and reduces potential damage to the parking brake cable. A pivot lever 60 is pivotally mounted on one brake shoe 20. Upper and lower portions of the pivot lever functionally engage with the other brake shoe 30 via struts 81, 70. A parking brake actuator 90 which pivotally supports on the upper strut 81 and activates upon an activation of a parking brake is arranged to be adjacent to a service brake actuator which activates upon an activation of a service brake. Preferably an operational part of the parking brake actuator is projected out from the brake back plate.

Abstract: A brake adjuster comprises a variable length strut (16) having two end portions (30, 31) and an intermediate portion (32) therebetween which is in screw threaded engagement with one of the end portions (31). A pawl (39) is attached to the other end portion (30) and engages an array of ratchet teeth (38) the intermediate portion (32). As the end portions of the strut (30, 31) move apart during a brake application the pawl (39) rides up a flank of a ratchet tooth (38a) and if the movement apart exceeds a predetermined amount engages behind the tooth (38a). When the end portions (30, 31) move towards each other in the next brake disengagement, the intermediate portion (32) is rotated relative to said one of the end portions (31) to increase the effective length of the strut (16). The pawl (39) may be bi-metallic and arranged to disengage the ratchet teeth (38) if the temperature of the adjuster rises above a predetermined level.

Abstract: A adjustment lever (80) has dual-functions characterized in that when an actuating force to a brake shoe (20) to move outward reaches predetermined magnitude, a device (80g) prevents over-adjustment of shoe-to-drum clearances disables a device (70) to restrict return positions of brake shoes inhibiting the brake shoes movement in the direction to separate each other and when a brake temperature rises certain degree, a device (80d) to prevent over-adjustment of brake shoe-to-drum clearances disables the device (70) to restrict return position inhibiting the brake shoe movement as well.

The middle segment of a long link (11) is pivotable in the middle of the one brake shoe (2).
