Abstract
A force generating system including a lever mechanism fixed with respect to and interacting with a varying elastic deformation force take-up system and at a force application point of a given lever arm length; an energy-storing force generating device which acts upon the lever mechanism at a changeable position of its lever arm for supplying a portion of the energy stored in it when the lever arm length is increased and for at least partially taking up again the energy taken up by the force take-up system, when the lever arm length is decreased; and an adjusting arrangement for the controllable changing of the position in which the force generating device acts upon the lever arm of the lever mechanism. The force generating system is used in a disk brake system.

A force generating system for generating a reversible working stroke with a variable force acting upon a force take-up system which, because of varying elastic deformation, develops a counterforce which changes as a function of the stroke, comprising:
- a lever mechanism including a pivot point fixed with respect to a force take-up system and including a lever arm for interacting with said force take-up system at a force application point of a given lever arm length;
- an energy-storing force generating device which acts upon the lever mechanism at a changeable position of its lever arm for supplying a portion of the energy stored in it when the lever arm length is increased and, for at least partially taking up again the energy taken up by the force take-up system when the lever arm length is decreased;
- an adjusting arrangement for the controllable changing of the position in which the force generating device acts upon the lever arm of the lever mechanism;
- and
- a sensor for detecting the position in which the force generating device acts upon the lever arm of the lever mechanism.
In a brake system including a disk brake between a pair of brake shoes which form a force take-up system having elastic deformation varying over a working stroke and a force generating system for generating a reversible working stroke with a variable force to the brake shoes, the force generating system comprising:
- a lever mechanism including a pivot point fixed with respect to a force take-up system and including a lever arm for interacting with said force take-up system at a force application point of a given lever arm length;
- an energy-storing force generating device which acts upon the lever mechanism at a changeable position of its lever arm for supplying a portion of the energy stored in it when the lever arm length is increased and, for at least partially taking up again the energy taken up by the force take-up system when the lever arm length is decreased;
- an adjusting arrangement for the controllable changing of the position in which the force generating device acts upon the lever arm of the lever mechanism;
- and
- a sensor for detecting the momentary angular position of the force generating device.
