Abstract
The vehicle drum brake comprises a plate, at least one segment comprising a core and a brake lining, a spring able to keep the core of the segment in an axially balanced position, means for prestressing the spring wherein said means for prestressing the spring include stop means limiting the ability of the core of the segment to move axially.
Claims14
A drum brake, comprising:
- a plate;
- at least one segment including a core and a brake lining;
- a spring configured to keep the core of the segment in an axially balanced position;
- means for prestressing the spring in a prestressing direction;
- and
- stop means configured to limit an ability of the core of the segment to move axially in a stopping direction,
- wherein the stop means and the prestressing means are separate parts,
- wherein the stop means include an axial skirt outside the spring and extending in an axial direction that is parallel to an axis of the spring,
- wherein the stop means include a washer rigidly attached to the axial skirt,
- wherein the stopping direction is the same as the prestressing direction and the axial direction,
- wherein the axial skirt has a length in the axial direction that is equal to or greater than a compressed length of the spring in the axial direction, the compressed length being a length of the spring in the axial direction concurrently with the spring being at least partially compressed in the axial direction,
- wherein,
- the prestressing means include a stud anchored to the plate by a first extremity, a second extremity of which defines an end-of-travel position for the washer,
- the spring contacts the washer at a spring contact point of the washer,
- the stud contacts the washer at a stud contact oint of the washer, and
- the washer includes a central recess, and the stud contact point is at the central recess, such that the spring contact point is distal from the core in relation to the stud contact point in the axail direction.
