A brake dust trap for a drum brake, the brake dust trap having an annular shape arranged to be received in a groove formed circumferentially in a drum of the drum brake to trap particulate matter generated by the drum brake, wherein the brake dust trap is arranged to be retained in the groove to rotate along with the drum, and removable from the drum brake for disposal of trapped particulate matter.

Brake dust trap for a drum brake

A brake drum system () for a wheel of a vehicle, comprising a brake drum () rotatable with the wheel, the brake drum having an inner surface () adapted to receive a friction-generating lining when a driver applies the brakes of the vehicle; a wheel end hub () adapted to be located radially between a drive axle of the vehicle and the brake drum (); and a substantially circular spring element () for concentrically aligning the brake drum () with the wheel end hub (), the spring element being adapted to be clamped between the brake drum and the wheel end hub for providing a radially directed spring force, wherein the spring element has an outer surface adapted to be pressed against the brake drum and an inner surface adapted to be pressed against the wheel end hub.

Brake drum system for a wheel of a vehicle

The present disclosure relates to a brake drum for a drum brake for a vehicle. The brake drum comprises a braking surface adapted to receive at least one brake shoe of the drum brake. The brake drum further comprises a cooling arrangement comprising a set of cooling conduits located between a braking surface and an outer surface. The material of the brake drum located radially between the set of cooling conduits and the braking surface at an inner axial cross-section has an inner axial aggregate thermal conductance and the material of the brake drum located radially between the set of cooling conduits and the braking surface at the outer axial cross-section has an outer axial aggregate thermal conductance. Accordingly, the inner axial aggregate thermal conductance is different from the outer axial aggregate thermal conductance.
