Damping device for e.g. car, has crosspiece whose ends are connected to grooves, such that crosspiece is in helical-sliding connection with cylindrical body to transform uni-axial stress of tube into biaxial torsion compression stress

摘要

The device has a deformable tube (14) and a transmission unit with a hollow cylindrical body (10) that is provided with helical grooves (25). The cylindrical body actuates a crosspiece (12) associated with a disk. Ends of the crosspiece are connected to the grooves, such that the crosspiece is in helical-sliding connection with the body to transform uni-axial stress of the tube into biaxial torsion compression stress. Independent claims are also included for the following: (A) a road transport vehicle including a damper device (B) a railway transport vehicle including a damping device (C) an overhead transport vehicle including a damping device (D) a device for testing plastic behavior of different material and including a damping device.
