Patent number: 11987192Abstract: A bumper crossmember for a motor vehicle having a crossmember extending transversely to the longitudinal axis of the vehicle and two crashboxes connected thereto. Each crashbox is connected with its end facing away from the vehicle to the crossmember in a respective end section thereof, and with its end facing the vehicle is connectable to a structural component of the vehicle, e.g., a longitudinal member. The crossmember has a corrugated structure in the area where a crashbox is connected. A tow sleeve is integrated into the bumper crossmember in the connection area of the crashbox. The tow sleeve is held in a vertex structure of the corrugated structure in a form-fitting manner in the z and y directions, the vertex area of this vertex structure facing away from the crashbox, with the lateral surface of the tow sleeve on the flanks facing one another and forming the vertex structure.Type: GrantFiled: September 3, 2020Date of Patent: May 21, 2024Assignee: KIRCHHOFF AUTOMOTIVE DEUTSCHLAND GMBHInventors: Alexander Günther, Lena Kremer, Maria Schmitt, Marco Töller

Patent number: 11912218Abstract: A bumper crossmember comprising a wave structure oriented in the vertical direction (z direction), wherein the wave structure comprises at least three apex structures which extend in the bumper crossmember longitudinal direction and are adjacent in the vertical direction. This crossmember comprises a first length section that follows its longitudinal extent, at least one second length section that follows its longitudinal extent, and at least one transition section that is arranged respectively between these length sections. In the second length section, the wave structure is inverted with respect to the first length section, in that the opening direction of the apex structures switches in the transition section. In the transition section, there is at least one additional apex-forming structure, the apex of which is offset in the frontal direction (x direction) with respect to a frontal plane (yz-plane) in which at least two apex structures that are adjacent in the longitudinal sections lie.Type: GrantFiled: January 24, 2020Date of Patent: February 27, 2024Assignee: KIRCHHOFF AUTOMOTIVE DEUTSCHLAND GMBHInventors: Patrick Tlauka, Cristina Matthey, Ralf Stegmeyer, Rolf Peter Röttger, Marco Töller, Rolf Schwarzer, Stephan Lagin, Maria Schmitt, Lena Kremer

Patent number: 8793998Abstract: A torque transmission device includes a first shaft is coaxially borne relative to a second shaft via at least one roller bearing. An adjusting device adjusts the amount of torque transmitted from the first shaft to the second shaft by changing the internal bearing friction experienced by the at least one roller bearing. In one embodiment, the adjusting device causes one ring of the at least one roller bearing to axially displace relative to a second ring of the at least one roller bearing, thereby changing the amount of bearing friction experienced by roller bodies disposed between the first and second rings and thus the amount of torque transmitted from the first shaft to the second shaft.Type: GrantFiled: December 10, 2009Date of Patent: August 5, 2014Assignee: Aktiebolaget SKFInventor: Marco Schmitt

Patent number: 8360020Abstract: A method for determining a scanning ratio for a characteristic curve for the operation of an electromechanical valve for a camshaft adjuster in which an ambient temperature and a relative motion of a camshaft are determined at a reference point. In accordance with a specific ambient temperature and other operating conditions such as e.g., engine rpm, a holding scanning ratio is determined. Subsequently, at least one additional scanning ratio of an operating state is determined for a scanning ratio characteristic for the valve.Type: GrantFiled: November 24, 2007Date of Patent: January 29, 2013Assignee: Schaeffler Technologies AG & Co. KGInventors: Jochen Auchter, Marco Schmitt

Patent number: 7387097Abstract: The invention relates to a device (101) for varying the control times of gas exchange valves of an internal combustion engine, with a hydraulic actuation device (102) and with a control valve (103). The device (101) according to the invention is provided with mid-position locking of a hydraulic actuation device (102). Furthermore, the device (101) according to the invention ensures that, in the event of the failure of an actuation unit (112) which regulates the control valve (103), the hydraulic actuation device (102) is locked in the mid-position and the lock is maintained until the actuation unit (112) is repaired. Furthermore, the device (101) according to the invention makes it possible to start the internal combustion engine in a position locked in a mid-position, without a movable element (105) of the hydraulic actuation device (102) butting against a side wall of a pressure space (104) when the internal combustion engine is started.Type: GrantFiled: October 5, 2005Date of Patent: June 17, 2008Assignee: Ina-Schaeffler JGInventors: Marco Schmitt, Jochen Auchter

Patent number: 7261072Abstract: The invention relates to a device (101) for altering the control times of gas exchange valves of an internal combustion engine, having a hydraulic actuating device (102) and a control valve (103). The device (101) according to the invention is provided with centre-position locking of a hydraulic actuating device (102). Furthermore, the device (101) according to the invention ensures that if an actuating unit (112) which governs the control valve (103) fails, the hydraulic actuating device (102) is locked in the central position and the locking is maintained until the actuating unit (112) is repaired. Furthermore, the device (101) according to the invention allows the internal combustion engine to be started in a locked position in a central position without a moveable element (105) of the hydraulic actuating device (102) striking a side wall of a pressure space (104) when the internal combustion engine is started.Type: GrantFiled: October 6, 2005Date of Patent: August 28, 2007Assignee: Schaeffler KGInventor: Marco Schmitt
