Abstract
A method for ascertaining an operating variable of a drum brake, the method using forces acting on supporting bearings. The invention further relates to an associated drum brake assembly, an associated analysis unit and an associated storage medium.
Claims10
A method for ascertaining an operating variable of a drum brake, the method comprising:
- measuring a first bearing force on a leading brake shoe of the drum brake with a first sensor;
- measuring a further bearing force on a trailing brake shoe of the drum brake with a second sensor;
- recording the first bearing force and the second bearing force;
- calculating an operating variable, wherein the operating variable is a brake torque based on a difference between the first bearing force and the further bearing force multiplied by a predetermined factor;
- and
- applying the calculated braking torque to the drum brake.
3 more elements
A drum brake assembly comprising:
- a leading brake shoe;
- at least one supporting bearing for the leading brake shoe;
- a trailing brake shoe;
- at least one further supporting bearing for the trailing brake shoe;
- at least one force sensor on the supporting bearing for measuring a bearing force produced in the supporting bearing by the leading brake shoe;
- at least one further force sensor on the further supporting bearing for measuring a bearing force produced in the further supporting bearing by the trailing brake shoe;
- and
- an analysis unit, having instructions for calculating an operating variable, wherein the operating variable is a brake torque based on a difference between the first bearing force and the further bearing force multiplied by a predetermined factor.
