Embodiment Construction

[0022] according to figure 1 The view shows the roll compensation system with height adjustment of the bogie frame by means of hydraulic cylinders, which are arranged inside the main helical pressure spring and are always lifted against gravity on the outside of the curve, and on the curve descend on the inside.

[0023] This function advantageously has the effect of increasing the superelevation effect in curves, so that by increasing the travel speed in curves the travel time of rail vehicles on the corresponding section can be shortened without changing the track layout.

[0024] The height adjustment not only compensates for the roll angle due to spring stiffness in the main and secondary spring stages, but also deliberately overcompensates, so that the maximum lateral acceleration acting on the passenger remains within the required range.

[0025] When a certain transverse acceleration threshold value is reached, the control unit raises / lowers the bogie frame at a value ...

Abstract

The invention relates to a rocking compensation system for rail vehicles, wherein actuators are arranged within the primary helical compression springs of the bogies for targeted height adjustment of the bogie frame.

Description

technical field [0001] The invention relates to a roll compensation system for a rail vehicle. Background technique [0002] When the rail vehicle is running on a curve, a torque is generated due to the centrifugal force, whereby the vehicle is tilted in the direction of the outer side of the arc. Due to this inclination, the coordinate system is also rotated for the passengers in the compartment and a component of the acceleration due to gravity now acts as a lateral acceleration, which can be perceived as particularly disturbing. [0003] Especially when driving quickly through curves with high transverse accelerations on the wheelset, the permissible values ​​for the passengers would be significantly exceeded without additional measures. [0004] The so-called leaning technique is known from the prior art for car control in connection with track curves, in which a car of a railway vehicle can tilt to the inside of the curve and thereby reduce the perceived lateral accele...
