Publication number: 20200189645Abstract: An inner column is adjustable (movable) relative to an outer column in a vehicle body front-rear direction. Multiple wire insertion holes are provided in a wire locking member attached to a lower portion of the inner column. Inserting a wire insertion portion of the wire member into one of the wire insertion holes from each of the left and right sides restricts movement of the inner column relative to the outer column and the locked mechanism is set to a locked state. Operating an operation lever to turn a turning shaft turns and moves a cam portion on an outer peripheral portion of the turning shaft integrally with the operation lever. In this case, left and right tilted surfaces of the cam portion expands the wire member to the left and right and causes the wire insertion portions to disengage from the wire insertion holes to unlock the lock mechanism.Type: ApplicationFiled: December 16, 2019Publication date: June 18, 2020Inventor: Osamu FUJIMURA

Publication number: 20200189647Abstract: A steering shaft for a motor vehicle includes a hollow shaft and an inner shaft which is arranged coaxially in the hollow shaft. The inner shaft is configured to be telescoped relative to the hollow shaft in the direction of the longitudinal axis of the steering shaft and is connected in a torque-transmitting manner to the hollow shaft via at least one rolling body. The rolling body is received in a rolling body cage such that it can roll in the direction of the longitudinal axis between the inner shaft and the hollow shaft. In order to achieve a high operational reliability with a relatively low manufacturing complexity, the rolling body cage has at least one seal element which bears sealingly against the hollow shaft and/or the inner shaft.Type: ApplicationFiled: December 4, 2017Publication date: June 18, 2020Applicants: THYSSENKRUPP PRESTA AG, thyssenkrupp AGInventor: René Marco SCHMIDT

Publication number: 20200189648Abstract: A steering column may include an inner casing tube that rotatably mounts a steering shaft, an outer casing unit in which the inner casing tube is displaceable and fixable in an axial direction, and an energy absorption device operatively disposed between the casing tube and the casing unit. The energy absorption device absorbs at least some energy in a crash event when the casing tube is telescopically displaced relative to the casing unit. The energy absorption device may have at least two deformation strips fastened to the casing tube, and a deformation slide may be disposed on each strip. Each deformation slide may be connected to the casing unit and may encompass and jam external narrow sides of the respective deformation strip so that each deformation slide deforms the respective deformation strip when the deformation slide in a crash event is displaced in the axial direction on the deformation strip.Type: ApplicationFiled: October 18, 2017Publication date: June 18, 2020Applicants: THYSSENKRUPP PRESTA AG, thyssenkrupp AGInventor: Markus DOMIG

Publication number: 20200189649Abstract: A steer-by-wire steering system for a motorized vehicle includes a feedback actuator to simulate a steering feel to a steering device. The feedback actuator has an electric motor with a motor shaft connected to a driver input shaft to be able to transmit a torque. The motor shaft is able to be rotated in at least one rolling bearing. The rolling elements of the at least one rolling bearing are arranged in a magnetorheological fluid and the feedback actuator further includes an electromagnet to pass a magnetic field through said magnetorheological fluid for stiffening the fluid and restricting movement of the rolling element.Type: ApplicationFiled: August 29, 2017Publication date: June 18, 2020Applicants: THYSSENKRUPP PRESTA AG, thyssenkrupp AGInventors: Kristof POLMANS, Imre SZEPESSY, Arne SCHACHT, Markus DOLD
