Problems solved by technology

However, when the elasticity of the caliper is high (and therefore low stiffness), the overall properties of the friction brake change only slightly, because the changed lining elasticity does not play a significant role

Embodiment Construction

[0021] then with the help of figure 1 The invention is further explained by way of example with the aid of a schematically shown friction brake 1 in the form of a floating caliper disc brake. Floating caliper disc brakes are sufficiently known per se, so that the properties and function of floating caliper disc brakes and the basic installation of eg floating caliper disc brakes in vehicles are not further explained here. In principle, however, the invention can also be used for other types of brakes, for example drum brakes. It is also possible to provide another friction surface than a brake disc or a brake drum, for example a more or less flat surface, for example as a brake for a linear movement.

[0022] figure 1 A friction brake 1 is shown comprising a floating brake caliper 2 as a brake caliper, which surrounds a friction surface in the form of a brake disk 4 here. A fixed (with respect to the floating brake caliper 2 ) brake lining 3 and a movable (likewise with r...

Abstract

In an electrically actuated friction brake (1) with a nonlinear force-distance behaviour, in which an actuating part of a pressing device (10) is rotated for braking by an actuating means (20) between an initial actuating angle (alphaA) and a final actuating angle (alphaE) in order to press a brake lining (6) against a friction surface to generate a braking torque (TB), the influence of the brake lining elasticity, which changes due to wear, cannot be ignored. The thereby changing force-distance behaviour of the friction brake (1) is compensated by adjusting the initial actuating angle (alphaA) of the actuating part for the friction brake (1) on the basis of the current wear state of the brake lining (6).

Description

technical field [0001] The invention relates to a braking system with an electrically actuated, non-linear friction brake and a method for operating an electrically actuated, non-linear friction brake, wherein, for braking, an actuating part of a pressure device is activated via an actuating mechanism Rotation between the initial actuation angle and the final actuation angle in order to press the brake lining against the friction surface to generate a braking torque, wherein the pressing device is arranged on the wear adjuster. Background technique [0002] In addition to conventional hydraulic and pneumatic brakes, variously actuated friction brakes are known today, which for example press the friction linings by means of an electric motor onto the friction surfaces of the friction brake, such as screw drives (for example for parking brakes, but experimentally also used for running brakes) or so-called wedge brakes, as described, for example, in DE 103 92 252 B4. Therein, ...
