Publication number: 20160186825Abstract: A combined vehicle brake which has a hydraulically actuable service brake and an electromechanically actuable parking brake device. The present invention is based on the problem of improving the known ball screw drives for use in vehicle brakes, of making simple automated assembly possible, and in addition of opening up the possibility to increase cycle times. A spring element of double helical type which is configured differently in sections is provided, in a middle section, that is to say in the drive thread turn, which substantially do not impede the elastically pliable adaption of the spring element to the helically wound drive thread turn, and wherein a bearing section is additionally provided at at least one end of the spring element, which bearing section has an increased transverse rigidity or has it impressed onto it in comparison with the middle section.Type: ApplicationFiled: August 4, 2014Publication date: June 30, 2016Inventors: Thomas Winkler, Dieter Füller, Thomas Hess, Patrick Walter, Jürgen Bauer, Jürgen Völkel

Patent number: 8925692Abstract: A system and method for an electromechanically actuable parking brake for motor vehicles, which is embodied as a drum brake of the “duo-servo” type. The parking brake has a brake actuating device which can be actuated by an electromechanical actuator, is designed as an expander element and acts on two brake shoes, the expander element being supported via a spring energy storage device, may be designed as a diaphragm spring assembly, and being spreadable by a predetermined length of travel, when the parking brake is actuated, to apply an application force. In order to provide a sufficiently large hot parking travel, the length of travel travelled by the expander element to apply the application force when the parking brake is actuated can be moved as a function of at least one motor vehicle state parameter.Type: GrantFiled: September 4, 2008Date of Patent: January 6, 2015Assignee: Continental Teves AG & Co oHGInventors: Joachim Funke, Rüdiger Puff, Jürgen Völkel

Patent number: 8794720Abstract: A method to limit overheating of a brake equipped with an electromechanically actuable parking brake including the steps of: driving a threaded spindle by an electric motor until a power drain (Imax), corresponding to a brake application force (F), is reached; detection of a travel distance (x0) of the piston corresponding to the brake application force (F) of the brake caliper in a locked state; determination of a second travel distance (x1) by adding a further travel distance value (x11), which corresponds to the desired clearance value, to form (x0); driving of the electric motor until the second travel distance (x1) has been covered by the brake piston; and comparing the vehicle speed with a predefined first speed value, at the upward transgression of which the electric motor is driven once more in the release direction until a further, previously defined travel distance (x12) has been covered.Type: GrantFiled: September 3, 2008Date of Patent: August 5, 2014Assignee: Continental Teves AG & Co. oHGInventors: Marcus Schumann, Christof Maron, Jürgen Völkel
