Abstract

The invention relates to a wheelset for vehicles, particularly for rail vehicles, comprising a first wheel (1), a second wheel (2) and an axle (3), wherein the axle (3) comprises at least a first shaft portion (4), a second shaft portion (5) and a third shaft portion (6) which are connected to one another, wherein at least one shaft portion of the at least first shaft portion (4), the second shaft portion (5) and the third shaft portion (6) is designed as a hollow shaft which can be filled with a fluid, or at least comprises a cavity which can be filled with fluid. According to the invention, at least the first shaft portion (4) is detachably connected to the second shaft portion (5) to create advantageous construction conditions. This provides a wheelset system which can be flexibly designed and allows for component integrity monitoring.

Description

technical field [0001] The invention relates to a wheel set for a vehicle, in particular for a rail vehicle, having a first wheel, a second wheel and a wheel set shaft, wherein the wheel set shaft comprises at least one first shaft part , a second shaft and a third shaft, the first shaft, the second shaft and the third shaft are connected to each other, wherein at least the first shaft, the second shaft and the third shaft At least one of the shaft parts is configured as a hollow shaft that can be filled with a fluid or has at least one cavity that can be filled with a fluid. Background technique [0002] Wheel axles must transmit forces between the wheels and enable the arrangement of wheel components, such as drive and brake components, wheel bearings, etc., on the wheels. In addition, high component and operational safety, low mass, long service life and low costs are design goals. Since wheelsets are safety-relevant components, condition assessment is important in orde...
