Abstract

A rocking compensation system for rail vehicles includes actuators which are arranged within primary helical compression springs of bogies for a targeted height adjustment of a bogie frame of the bogie.

Claims (9)

1. A roll compensation system for rail vehicles, having a car body, a wheel axle and a bogie with a bogie frame, the roll compensation system comprising:

a primary helical spring stage with primary compression springs;

a secondary spring stage with secondary compression springs;

said secondary spring stage disposed between the bogie and the car body; and

actuators disposed between the wheel axle and the bogie frame and within said primary helical compression springs for a targeted height adjustment of the bogie frame.

2. The roll compensation system as claimed in claim 1 , wherein operating modes are assigned to a moving vehicle, and a predetermined control of the bogie frame by the actuators is assigned to each operating mode.

3. The roll compensation system as claimed in claim 2 , wherein the operating modes include “straight ahead”, “curve to left” and “curve to right”, and wherein a one-sided height adjustment of the bogie frame occurs in the operating modes “curve to left” and “curve to right”.

4. The roll compensation system as claimed in claim 3 , wherein the predetermined height adjustment compensates for a tilt angle of approximately 3 degrees.

5. The roll compensation system as claimed in claim 1 , wherein the actuators are hydraulic cylinders.
