摘要： A drum brake assembly for use with a wheel end electric drive motor arrangement can generate brake dust, which may accumulate on the electric motor and cause heat retention problems that are detrimental to motor performance and longevity. These issues are addressed by providing an assembly including a support attachable to a vehicle axle element, brake shoes pivotally mountable on the support, and a wheel spindle interconnected with one end of the axle element. A wheel hub is rotatable around the spindle, and an electric motor unit is disposed between an end of the axle element and the spindle to produce rotation of the hub relative to the axle element. A brake drum is securable to the hub for rotation with the hub relative to the spindle by way of the electric motor unit. The brake drum includes a circumferential perimeter wall overlying the brake shoes, and a fan rotor is interconnected with that wall for rotation together with the drum and the wheel hub relative to the spindle. A perforated dust shield is attachable to the support on an axial side of the brake shoes opposite the fan rotor, such that, during vehicle operation, air drawn by blades on the fan rotor through openings in a wall of the brake drum carries debris out through perforations in the dust shield and away from the wheel end motor and brake assembly. A vehicle including the assembly mentioned and a process of ventilating that assembly are also discussed.

摘要： 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.

摘要： The rotation-actuated drum brake uses both inner and outer sets of brake shoes, which are actuated in a radial manner, to contact the inner and outer surfaces of a cylindrical brake drum. The inner and outer sets of brake shoes are disposed within an annular brake housing and are constrained to move radially. An actuator selectively drives rotation of a rotating disc having a plurality of arcuate slots defined therein. This drives roller guides of the inner and outer sets of brake shoes to roll within respective ones of the arcuate slots. The driven rolling of the roller guides drives the radial motion of the inner and outer sets of brake shoes to simultaneously frictionally engage the inner and outer surfaces of the cylindrical brake drum.

摘要： An illustrative example drum brake device includes a drum having an inner, braking surface. At least one brake shoe includes a friction lining and a support structure for the friction lining. The support structure includes a window having a first portion that is wider than a second portion. A shoe mount is configured to be received through the first portion of the window and engage the support structure adjacent the second portion of the window in a manner that resists movement of the brake shoe in two dimensions and allows selective movement of the brake shoe in a third dimension for allowing the friction lining to selectively engage the braking surface.
