20080196984 | Parking brake device and vehicle brake system provided with such a parking brake device - The invention relates to a parking brake device comprising a spring element and an actuating element that acts upon the spring element, wherein by applying an actuating force to the actuating element the parking brake device is transferrable between a brake-inactive release position and a brake-active parking position. In the invention, it is provided that the spring element is biased in the release position and that the spring element upon transfer from the release position to the parking position yields only upon attainment of an actuating-force threshold value that is determined by the bias. | 08-21-2008 |
20090050420 | Reduced-Noise Electric Brake Actuator - An electric brake actuator is described. The actuator comprises a housing, an electric motor, a device for torque transmission and an element for torque delivery. The device for torque transmission is a gear mechanism with a gear shaft which is parallel to the motor shaft, wherein the torque is transmitted from the electric motor to the gear mechanism by means of a belt drive. The distance between the motor shaft and the gear shaft is fixed by means of a rigid spacer, the opposite ends of which are located on different sides of the plane which is defined by a belt of the belt drive. | 02-26-2009 |
20100314207 | ACTUATOR DEVICE AND METHOD FOR CONTROLLING THE ACTUATOR DEVICE - An actuator device for use in a land vehicle, comprising an actuator for actuating a wheel brake of the land vehicle, a control unit for controlling the actuator and a processing unit. The processing unit is connected to the control unit and an external main control unit in order to route signals of the main control unit to the control unit. The actuator device further comprises a memory for storing actuator-specific information. This memory is connected to a monitoring unit. The monitoring unit is connected in turn to the control unit and the processing unit. | 12-16-2010 |
20100320041 | Single-Part Carrier for an Electric Parking Brake Actuator with Planetary Gear Set - A brake actuator for an electrical parking brake comprises an electric motor and a planetary gear set. The axes on which the planet wheels are carried on the planet carrier are joined substance-to-substance to the planet carrier, i.e. formed in one piece with it or for instance mounted on its surface by means of atomic or molecular forces. Recesses on the axes can receive a lubricant. Spacers between the planet carrier and planet wheels can reduce the contact surface in the axial direction. | 12-23-2010 |
20130180811 | Assembly for an Electromechanical Brake Actuator - The invention relates to an assembly for a brake actuator which is provided, for example, for an electromechanically operated parking brake. The assembly comprises a drive device and a gear device for generating and transmitting a torque to a brake device, a carrier element having a first mounting device to which the drive device and the gear device are mechanically secured, and a housing having a housing lower portion which has a second mounting device, on which the carrier element together with the drive device and gear device is arranged in a self-supporting manner by means of the first mounting device. | 07-18-2013 |
20130203554 | Sub-Assembly for an Electromechanical Brake Actuator - The invention relates to a subassembly for a brake actuator, which is provided for an electromechanically operated parking brake. The subassembly comprises a drive device and a gearing device, which comprises in succession a first, second and third gear stage for transmitting a torque generated by the drive device. The first gear stage is designed in the form of a gearwheel or belt drive, the second gear stage is designed in the form of a gearwheel mechanism, and the third gear stage is designed in the form of a planetary gear, wherein a planet carrier of the third gear stage receives a first gearing shaft for a sun gear of the planetary gear and an output-side gearwheel of the second gear stage that is coupled to rotate with the sun gear, and bearing elements for planet gears of the third gear stage. The invention further relates to an electromechanical brake actuator and to an electric parking brake, which include the sub-assembly. | 08-08-2013 |
20130213746 | Vehicle Brake System for a Motor Vehicle and Method for Controlling the Vehicle Brake System When the Parking Brake Function is Activated - A vehicle brake system, comprising a hydraulically controllable disk brake device, which has an electromechanical actuating device for activating a parking brake function, wherein the vehicle brake system has a hydraulic circuit having a hydraulic pressure source and controllable hydraulic functional elements in order to hydraulically control the disk brake device according to a service brake action of a driver or according to an automatic activation of a driving assistance system, wherein the vehicle brake system further comprises a control device in order to control the electromechanical actuating device according to a parking brake action of the driver or according to an automatic activation of the parking brake function. In order to avoid overload states the control device is designed to control at least one of the hydraulic functional elements in such a way that, before the parking brake function is activated by controlling the electromechanical actuating device, a hydraulic volume currently acting on the disk brake device in order to produce a hydraulic pressure that causes a service brake action can be hydraulically isolated. | 08-22-2013 |
