SU1252213A1 - Device for transmitting torque to wheel pair - Google Patents

Description

This invention relates to railway transport, in particular to wheelsets of rail vehicles.

The purpose of the invention is to improve the speaking performance by ensuring an even distribution of the traction moment over the wheels.

The drawing shows the device dll transmission of torque to the wheelset.

The device contains a hollow shaft 1 output element 2 of the gearbox, spanning axis 3, on which the wheels 4 and rigid elements 5 and 6 connected to the wheels 4 and the hollow shaft 1 are rigidly fixed. The tangential stiffnesses of the elastic elements 5 and 6 are chosen from the following expression:

The device works as follows.

When transmitting the torque moment 15 from the output element 2 of the gearbox to the wheels 4, it is distributed between the left and right wheels 4 in proportion to the tangential stiffnesses of the respective power branches. But 20, since these stiffnesses are the same, then the moments transmitted to the wheels 4 are the same, i.e. In the contacts of the left and right wheels 4 with the rails, in general, the same sy-, 2S coupling loops arise.
