Abstract
A brake drum for a drum brake of a motor vehicle, the brake drum having: a ring section extending concentrically about a rotation axis; and a circular wall section extending at an angle to the rotation axis; wherein in the brake drum has at least one portion that deviates from at least one of: a) a rotation symmetric configuration of the brake drum with respect to the rotation axis; b) a material comprised by at least one other portion of the brake drum.
Claims8
A brake drum for a drum brake of a motor vehicle,
- the brake drum having:
- a ring section extending concentrically about a rotation axis;
- and
- a circular wall section extending at an angle to the rotation axis;
- wherein the brake drum has at least one portion such that the brake drum itself is rotation asymmetric with respect to the rotation axis, and
- wherein the at least one portion deviates from
- a rotation symmetric configuration of the brake drum with respect to the rotation axis;
- wherein the at least one portion comprises at least one recess extending axially inward from an axial end face of the ring section, and
- wherein the at least one recess is positioned rotation asymmetric with respect to the rotation axis.
