Publication number: 20220228635Abstract: A drum brake having a brake drum, brake shoes, a carrier plate and a load measurement device in the region of an abutment is mountable on a steering knuckle. The abutment has a cylinder in which two pistons are guided, on the outer end faces of which the abutment ends of the brake shoes rest and the inner end faces of which are each supported by a spring on a step in the cylinder. A hollow peg projects from the outside of the cylinder and penetrates an opening in the carrier plate, such that it can be received in a receiving space in the steering knuckle resting on the carrier plate or in a reinforcement element fixed on the steering knuckle.Type: ApplicationFiled: May 20, 2020Publication date: July 21, 2022Applicant: Continental Teves AG & Co.

Patent number: 10752226Abstract: A brake device having a hydraulic booster stage for a hydraulic motor vehicle brake system is provided, which brake device, within normal boosting operation, can be operated both in an autonomous, driver-independent actuation mode with electronic control and in a manual actuation mode controlled by the driver, and outside normal boosting operation, can be operated in an emergency mode with a non-boosted actuation force generated by the driver alone, in the case of which brake device it is proposed that, within normal boosting operation, each actuation mode is assigned a dedicated piston in a booster housing of the booster stage, which piston is acted on directly with the boosting force and transmits this mechanically to components connected functionally downstream.Type: GrantFiled: November 18, 2016Date of Patent: August 25, 2020Assignee: Continental Teves AG & Co. oHGInventors: Falk Petzold, Adrian Messner, Manfred Rüffer, Michael Jürging

Patent number: 9784264Abstract: A pump assembly for supplying negative pressure to a pneumatic brake booster, wherein the pump assembly has at least two elastic displacement elements which are moved by connecting rods, the connecting rods each being rotatably mounted on an eccentric element. The eccentric element has a bearing seat element and a force element. At least two eccentric elements are secured next to each other on a drive shaft that rotates about an axis of rotation and an interlocking anti-rotation device is provided that determines a defined angular position of the eccentric elements relative to each other about the axis of rotation. In order to improve the ease of assembly and simplify the manufacturability, the anti-rotation device is designed as shaped elements of the bearing seat element in such a way that they engage in each other in an interlocking manner when the eccentric elements are in a defined angular position relative to each other.Type: GrantFiled: April 25, 2014Date of Patent: October 10, 2017Assignee: Continental Teves AG & Co. oHGInventors: Stephan Krebs, Jens Bacher, Heinrich Kreh, Lazar Milisic, Michael Jürging, Marcel Niepenberg, Jose Gonzalez, Karlheinz Seitz, Hans-Michael Koppel, Falk Petzold, Rolf Fellinger, Thomas Oeffner, Paul Wiebe, Stefan Imhof, Manfred Rüffer
