摘要： The present invention to provides a drum brake that generates the same braking force when a vehicle moves forward and backward. A first lever is connected to a second lever by a strut. A fourth lever provided with an anchor member and a third lever for connecting the fourth lever and the first lever to the end of the fourth lever) opposite to the anchor member across a screw which is the center of swing of the fourth lever. Accordingly, when the vehicle moves forward, an anchor load is received by the anchor member and the second lever. When the vehicle moves backward, the anchor load is received by the anchor member and the first lever.

摘要： A drum brake is provided of the leading-trailing shoe type in which a single piece spring installed as a part of the assembly holds down the brake shoe assemblies against the backing plate and also retracts the shoes after brake actuation. The single piece spring also retains the lower ends of the shoes against the anchor plate. This arrangement eliminates the need for separate shoe hold-down springs and separate upper and lower return springs, resulting in a significant reduction in parts and labor for assembly.

摘要： A brake assembly including a pair of brake shoes having adjacent ends pivotally mounted to a support and an actuator disposed between the ends of the brake shoes. The brake shoe webs are recessed at one end to engage a fixed anchor pin. The recess provides an arcuate bearing surface adapted to bear against a portion of the pin and permit pivoting movement of the brake shoe about the pin as the brake is actuated and released. The recess is also so oriented relative to the pin that the recess abuts the pin and prevents the brake shoe from moving away from the anchor pin. The brake assembly also includes an anchor pin having axially spaced cylindrical bearing areas adapted to radially, slidably receive the open ended recesses of a dual web brake shoe and a pair of oppositely facing surfaces extending radially outward at axially spaced locations on the pin to abut the brake shoe webs and prevent the anchor pin from being axially displaced from the support.

摘要： Backing plates are normally bolted to wheel gear housings and brake shoes are normally biased against such backing plates. Hydraulic or pneumatic lines normally proceed externally of the housing and over the backing plate to connect with a wheel cylinder which motivates the brake shoes. Such hydraulic lines can be easily damaged. A wheel brake arrangement (10) is disclosed which eliminates external hydraulic or pneumatic lines and eliminates such a backing plate. At least one conduit (33) is formed within a housing (12). The conduit (33) is connected directly to a wheel cylinder (28). The wheel cylinder (28) is mounted to one end (24) of the housing (12). A biasing structure (50) can serve for biasing a brake shoe (26) into contacting relation with one end (24) of the housing (12). A piloting arrangement (49) can serve for properly aligning the wheel cylinder (28) to motivate the brake shoe (26) and to receive pressurized fluid from the conduit (33).

摘要： A brake support assembly to be mounted on a vehicle axle housing for supporting a brake shoe assembly and an actuator therefor comprising a backing plate adapted to be fixedly mounted on a vehicle axle housing and two anchoring plates removably attached to the backing plate for pivotally supporting the brake assembly. Each anchoring plate includes projections which correspond to bores in the backing plate for positioning the anchoring plate at a predetermined position on the backing plate whereby the anchoring plate may be removed and replaced while maintaining a constant positioning of the brake assembly. In a first embodiment, the anchoring plate includes integral projections extending therefrom. In a second embodiment, the anchoring plate includes a tapered bore extending therethrough for supporting a pin. The pin extends from the plate defining the projection which corresponds with the bore in the backing plate. The backing plate also includes a pocket for retaining a spherical bushing which provides a low friction support for the actuator shaft whereby the bushing allows for small amounts of variation in the alignment of the actuator shaft.

摘要： A drum brake assembly includes a pair of brake shoes which are movable to a braking position by a hydraulic actuator. In order to maintain the pair of brake shoes adjacent the drum an adjuster is disposed between the pair of brake shoes opposite the hydraulic actuator. The adjuster carries a parking mechanism to manually move the pair of brake shoes to the braking position independently of the hydraulic actuator. The parking mechanism comprises a pair of levers which are pivotally connected to projections on the adjuster and the levers oppose one of the pair of brake shoes such that pivoting of the pair of levers moves the adjuster and the other brake shoe away from the one brake shoe. A spacer and a washer are disposed between the one brake shoe and abutment surfaces on each pair of levers and the adjuster movably supports the spacer and the washer.
