| 摘要 |
The invention relates to a shaft arrangement, in particular a wheelset shaft arrangement for a rail vehicle, comprising a shaft element (105), in particular for transmitting a drive torque, a first hub element (106.1), and a second hub element (107.1), said shaft element (105) defining an axial direction, a radial direction, and a circumferential direction. The first hub element (106.1) and the second hub element (107.1) sit on the shaft element (105) adjacently to each other in the axial direction and in a fixed manner in the axial direction and in the circumferential direction. The first hub element (106.1) has a first rigidity in a load direction, in particular in the axial direction, while the second hub element (107.1) has a second rigidity in the load direction. A spacer unit (108) is arranged between the first hub element (106.1) and the second hub element (107.1) in the axial direction, said spacer unit (108) being connected to the first hub element (106.1) and the second hub element (107.1). The spacer unit (108) has a third rigidity in the load direction at least in an initial non-deformed state in order to reduce an operational axial force which acts upon the first hub element (106.1) and the second hub element (107.1) along the axial direction in particular when the shaft element (105) is bent, said third rigidity being lower than the first rigidity and/or the second rigidity. |
