Publication number: 20240084870Abstract: An end-stop control valve can progressively add end-of-stroke damping resistance to complement the damping force provided by a main piston in a damper tube. The end-stop control valve may include a piston that is secured on a piston rod and selectively engages a catch piston, both of which are longitudinally movable within the damper tube. As the piston approaches the catch piston, an annular pocket of hydraulic fluid is created longitudinally and radially between the piston and the catch piston. As the piston continues to approach the catch piston, a cross-sectional area through which hydraulic fluid exits the pocket decreases, thereby gradually increasing the resistance of the end-stop control valve. In addition, a spring disc secured on the piston rod may contact a valve seat on the catch piston and provide resistance by elastically deforming in a longitudinal direction before the contact surfaces of the piston and catch piston engage.Type: ApplicationFiled: November 21, 2022Publication date: March 14, 2024Applicants: Thyssenkrupp Bilstein of America Inc., thyssenkrupp AGInventors: Peter KROPCZYNSKI, Jayson MOORE, Thomas MCGUIRE

Publication number: 20240084873Abstract: An end-stop control valve can progressively add end-of-stroke damping resistance to complement the damping force provided by a main piston in a damper tube. The end-stop control valve may include a piston that selectively engages with a catch piston, both of which are longitudinally movable within the damper tube. To reduce bypass around the piston, a piston band wrapped at least partially around the piston may engage with a sidewall of the catch piston just prior to engagement of the catch piston and the piston, although at least some hydraulic fluid can flow through a pathway of the piston band. A spring disc that moves with the piston may also engage with the catch piston just prior to engagement between the catch piston and the piston. The spring disc may elastically deform to contribute end-of-stroke resistance leading up to engagement of the piston and the catch piston.Type: ApplicationFiled: November 21, 2022Publication date: March 14, 2024Applicants: Thyssenkrupp Bilstein of America Inc., thyssenkrupp AGInventors: Peter KROPCZYNSKI, Jayson MOORE

Publication number: 20240084872Abstract: A vibration damper includes an end-stop control valve that progressively adds end-of-stroke damping force to complement the damping force provided by a main piston. The end-stop control valve may include a valve piston assembly that has a valve piston insert, a piston that is disposed radially outside the valve piston insert, and a valve disc stack-up that is supported on a hub of the valve piston insert and a valve seat of the piston. The valve piston insert and the piston may be arranged so as to be longitudinally movable relative to one another. Consequently, the preload of the valve disc stack-up increases as the valve piston assembly contacts a catch piston and begins end-of-stroke damping. Transitioning from an initial preload to a maximum preload during the end-of-stroke damping event progressively increases damping resistance and thereby improves NVH characteristics.Type: ApplicationFiled: September 26, 2022Publication date: March 14, 2024Applicants: Thyssenkrupp Bilstein of America Inc., Thyssenkrupp AGInventor: Peter KROPCZYNSKI

Patent number: 11926376Abstract: A method for determining a risk of instability of a calculation of an angle ? of a steering shaft of a motor vehicle can be employed where a first gear wheel is fixed to the steering shaft and cooperates with a second gear wheel and a third gear wheel, which are smaller than the first gear wheel. The number of teeth of the first gear wheel is n. The number of teeth of the second gear wheel is m. And the number of teeth of the third gear wheel is m+1. The angles ? and ? of the two smaller gear wheels are determined and the angular position ? of the steering shaft is calculated by evaluating the equation ? = m * ? + ( m + 1 ) * ? - ( 2 ? m + 1 ) * k * ? 2 ? n , with ? being an angle of the sensor range and a whole number k given by k = round ? ( ( m + 1 ) * ? - m * ? ? ) , wherein the risk of instability is determined by calculation of a stability margin t according to t = k - ( ( m + 1 ) * ? - m * ? ? ) .Type: GrantFiled: February 2, 2018Date of Patent: March 12, 2024Assignees: thyssenkrupp Presta AG, thyssenkrupp AGInventor: Roland Gémesi
