Embodiment Construction

[0041] figure 1 According to the prior art, a schematic sectional view of a braking device 1 for a vehicle is shown. The braking device 1 here has an automated (automatic) parking brake (parking brake) which can apply a clamp for securing the vehicle by means of an actuator 2 (brake motor). tight. For this purpose, the actuator 2 of the parking brake drives a spindle 3 , in particular a spindle 3 , which is supported in the axial direction. At its end facing away from the actuator 2 the spindle 3 is provided with a spindle nut 4 which, in the pressed state of the automated parking brake, rests on the brake piston 5 . In this way, the parking brake transmits force electromechanically to the brake pads 8 , 8 ′ or to the brake disc 7 . In this case, the spindle nut abuts on the inner end face of the brake piston 5 (also referred to as the rear face of the brake piston base or the inner piston base). The spindle nut 4 is displaced in the axial direction during the rotational ...

Abstract

The invention relates to a method for carrying out a parking braking process in a motor vehicle having a service brake and a parking brake, wherein a hydraulic force component is superimposed on a mechanical force component in order to obtain the braking force for the parking brake. The total clamping force of the vehicle braking process. According to the invention it is provided that during each parking braking operation a superposition of these two force components takes place.

Description

technical field [0001] The invention relates to a braking device for a motor vehicle and a method for actuating the braking device by means of a superposition of different force components. Background technique [0002] The well-known automated parking brake systems, so-called APBs (automated parking brakes), are designed in such a way that they can usually be completely by means of parking brake actuators, for example by means of electromechanical actuators. brake to provide the necessary parking brake force. Only in a few special cases, e.g. when the parking brake actuator is hot and / or the voltage is low, the following can occur: e.g. the electromechanical actuator (also called electromechanical regulator) hydraulic assistance becomes necessary. The known parking brake systems can only provide the necessary parking brake force, since they are designed according to the corresponding load characteristics of the actuation by means of a single parking brake actuator. . In...
