Publication number: 20220196002Abstract: A reciprocating piston lubrication pump with a component is proposed having an opening, which has at least one cylinder-shaped part, and with at least one piston, which comprises a radially outer surface built at least partly by a coating. A clearance between the radially outer surface of the piston and the component is between 1 ?m and 20 ?m when the radially outer surface is positioned in the cylinder-shaped part. The surface hardness of the coating at the radially outer surface is 2 to 10 times higher than that of a region of the component, which forms the cylinder-shaped part.Type: ApplicationFiled: December 21, 2021Publication date: June 23, 2022Inventors: Xiaobo Zhou, Tobias Mueller, Azeez Abdul, Heinz Rühl, Christine Matta, Mohammed Faid, Ileana Nedelcu, Thomas Eichhorn, Gunther Wenskat

Patent number: 9944265Abstract: A method for controlling a brake pressure booster with hydraulic brake boosting wherein the activation of an additional pressure source takes place upon exceeding a specified brake cylinder pressure threshold value. The threshold value lying between 50% and 100%, preferably between 70% and 80%, of a pressure limit value, from which the operating travel/brake pressure curve without additional brake pressure assistance has a knee point. Further upon exceeding a specified piston rod activation travel limit value, which lies at 20% to 100% of the available travel, preferably at 40% to 60% of the available travel. Furthermore, the speed of the vehicle, its lateral deceleration and its longitudinal deceleration can be used as criteria. Deactivation takes place on falling below a specified piston rod deactivation travel limit value. Based on selection of activation/deactivation criteria additional brake pressure boosting can be operational during braking maneuvers.Type: GrantFiled: July 15, 2014Date of Patent: April 17, 2018Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Thomas Eichhorn

Patent number: 9889836Abstract: An electromechanical braking device for a braking system including a master brake cylinder including an electric motor, an adjustable output rod, and a gear, the electric motor being connected to the output rod at least via the gear so that a power transmission path is present via which a motor output is at least partially transmittable to the output rod so that the output rod is adjustable, the electromechanical braking device including at least one elastic component situated within the power transmission path which is configured so that the at least one elastic component is not compressible below a control point of the electromechanical braking device, but during the occurrence of pressure peaks in the master brake cylinder which are above the control point of the electromechanical braking device, the at least one elastic component is compressible. Also described is a braking system for a vehicle.Type: GrantFiled: May 5, 2014Date of Patent: February 13, 2018Assignee: ROBERT BOSCH GMBHInventors: Dirk Mahnkopf, Andreas Schlichenmaier, Stefan Seitz, Otmar Bussmann, Bertram Foitzik, Thomas Eichhorn
