Patent number: 9175737Abstract: A drum brake module for motor vehicles operable by electric motor and performs at least one parking brake function, having an electromechanical actuator mounted on one side of the armature plate and a rotational-translational movement converter converting a rotational drive rotational movement into a translational activation movement of brake shoes arranged on a side of the armature plate facing away from the actuator in a brake drum, and including at least one supporting device between the brake shoes such that the latter can carry out an activation movement in the direction of the brake drum. A drive nut is supported by the rotational-translational movement converter in an axially secure and rotatable fashion on the armature plate to assist the braking force. The drive nut drives a spindle arrangement mounted in a rotationally fixed and axially displaceable fashion and engages with an activation cable on at least one brake shoe.Type: GrantFiled: February 2, 2012Date of Patent: November 3, 2015Assignee: Continental Teves AG & Co. oHGInventors: Uwe Bach, Holger von Hayn, Ralf Sundheim, Wolfgang Ritter, Ahmed Sefo, Jürgen Balz, Jens Hoffmann, Martin Semsch, Götz Mehner, Dirk Sundheim

Patent number: 9132815Abstract: Disclosed is a brake actuation unit for actuating a ‘brake-by-wire’ type brake system for a motor vehicle. The brake system includes a brake booster operable via a brake pedal mounted on a shaft and via an electronic control unit depending on the driver's request, and an element to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. Also included are a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and is formed of a simulator spring, which is arranged in terms of effect between a force-transmitting part connected to the brake pedal and a simulator housing, which is mounted on the shaft by means of two bearings. The simulator housing (22) includes a cylindrical area (26) for the accommodation of the two bearings (27, 28). This measure renders it possible to reduce the deformations that occur during actuation of the pedal travel simulator to a great extent.Type: GrantFiled: August 3, 2006Date of Patent: September 15, 2015Assignee: Continental Teves AG & CO., OHGInventors: Holger Von Hayn, Jurgen Schonlau, Manfred Ruffer, Thomas Sellinger, Torsten Queisser, Lazar Milisic
