A brake assembly having a brake spider that may receive an anchor pin or a sleeve that receives an anchor pin. Features such as splines may be provided with the anchor pin to help secure the anchor pin to the brake spider or the sleeve. Engagement features may be provided with the sleeve to help secure the sleeve to the brake spider.

An axle assembly and a method of assembly. An outboard wheel is mounted to an outboard mounting arrangement of a wheel hub. An inboard wheel and a brake drum are mounted to an inboard mounting arrangement of the wheel hub such that a brake drum mounting arrangement of the brake drum is axially positioned between the inboard wheel and the inboard mounting arrangement.

A brake lock system for a pumpjack brake apparatus comprises a latch handle lever pivotally mounted at a location on a pumpjack, a countershaft rotatably mounted on the pumpjack, latch handle linkage, and control linkage that transitions movement and force of the latch handle lever to a latch arm with a latch dog for pivoting the latch arm to insert the latch dog in a notch in the pumpjack brake apparatus. The latch handle, latch handle linkage, control linkage, and latch arm have dimensions that provide a mechanical advantage of the latch handle lever over the latch arm.

A force-shunting device including a tube defining a main axis and an inner wall, a first member sliding within the tube, a primary leg arranged obliquely, attached to the first member and including a primary pad in frictional contact with the inner wall, such that, when an external force is applied in a first direction on the first member, the primary leg rubs, or grips by mechanical camming, against the inner wall, the tube thus reacting all or part of the external force, the device including a second member mounted within the tube, sliding along the main axis and securely provided with a driving element of the primary pad so as to reduce the friction on the inner wall, to unprime the rubbing or mechanical camming.

Disclosed is an electronic parking brake. The electronic parking brake is provided with an operating lever, which is configured to support first and second brake shoes, which are installed at both sides inside a drum, and push the first and second brake shoes toward an inner surface of the drum when a pivot lever is pulled, and is electronically activated to operate the pivot lever to brake the drum, and the electronic parking brake includes a housing mounted on a vehicle body; an actuator installed at the housing and configured to generate a driving force for braking; a power conversion unit having a nut member configured to be rotated by receiving the driving force from the actuator, and a spindle member screw-coupled to the nut member to allow a rectilinear movement; and a parking cable configured to move according to a reciprocal linear movement of the spindle member, operate the parking brake, release an operation of the parking brake, and be connected to an end of one side of the spindle member, wherein the parking cable has a predetermined length and is formed with a single integrated type steel bar body to prevent occurrence of a bending deformation.

A braking device including: a loading plate; a pair of front wheels and a pair of rear wheels; a handle provided with clamping units; buffer units installed at the loading plate; and a braking unit that includes: a plurality of engaging grooves formed along a rim of a circular recesses; a brake bar disposed between the rear wheels; an actuating link supported by the brake bar and connected to a hinge portion; a connecting link connected to the actuating link by an interlocking bar; a connecting spring connected to the brake bar and the interlocking bar, a push switch fixed at an upper side of the connecting link, and a foot brake pedal fixed at an upper side of the push switch and has a top surface exposed at the top of the loading plate.

In a braking apparatus, a forcing device forces a movable portion in a direction that places a friction member in contact with a rotating body. A braking force releasing device displaces the movable portion in a direction in which the friction member separates from the rotating body in opposition to the forcing device. A buffering member is disposed between a fixed portion and the movable portion, and is made of a flexible material. A deforming device deforms the buffering member by pressing the buffering member in a direction that is perpendicular to the direction of displacement of the movable portion.

The present disclosure relates to a drum brake and a noise prevention device of the drum brake. The drum brake is provided in a vehicle, and includes a brake drum provided to be mounted on a wheel and including at least one bolt accommodation hole and a noise prevention device connected to one end of an axle shaft and configured to connect an axle flange including at least one bolt hole and the brake drum. Accordingly, vibrations of the axle shaft and the drum brake may be separated to prevent squeal noise.
