Rail vehicle having increased side-wind stability

Abstract

The invention relates to a rail vehicle, for which a direction of travel is specified and which has a leading bogie at a front of the rail vehicle with respect to the direction of travel and a trailing bogie at the end of the rail vehicle which is directed counter to the direction of travel. The leading bogie and the trailing bogie are each equipped with an anti-roll stabilizer. The roll stiffnesses of the anti-roll stabilizers of the leading bogie and of the trailing bogie are selected to be different such that, when side wind acts on the rail vehicle, unequal wheel unloading at the leading and trailing bogies is counteracted.

1 - 7 . (canceled) 
     
     
         8 . A rail vehicle, comprising:
 a direction of travel defining a front end of the rail vehicle facing in the direction of travel and an end of the rail vehicle facing counter to the direction of travel;   a leading bogie at said front end and a trailing bogie at said end facing counter to the direction of travel, said leading bogie and said trailing bogie each being equipped with a respective anti-roll stabilizer;   said anti-roll stabilizers of said leading bogie and said trailing bogie having different roll stiffnesses, causing unequal wheel unloading on said leading and trailing bogies to be counteracted when the rail vehicle is subjected to a side wind.   
     
     
         9 . The rail vehicle according to  claim 8 , wherein said roll stiffnesses of said anti-roll stabilizers of said leading and trailing bogies cause minimal wheel unloading on said leading and trailing bogies when the rail vehicle is subjected to a side wind. 
     
     
         10 . The rail vehicle according to  claim 8 , wherein said roll stiffness of said anti-roll stabilizer of said leading bogie is less than said roll stiffness of said anti-roll stabilizer of said trailing bogie. 
     
     
         11 . The rail vehicle according to  claim 8 , wherein said anti-roll stabilizers of said leading and trailing bogies are each configured as secondary anti-roll stabilizers each being disposed between a car body of the rail vehicle and a respective bogie. 
     
     
         12 . The rail vehicle according to  claim 8 , wherein said anti-roll stabilizers of said leading and trailing bogies have torsion bars with differing torsional stiffnesses, implementing said different roll stiffnesses of said anti-roll stabilizers of said leading and trailing bogies. 
     
     
         13 . The rail vehicle according to  claim 8 , wherein said leading and trailing bogies each have a respective bogie frame and a respective lever with differing lengths disposed between said torsion bar and said bogie frame of each of said anti-roll stabilizers, implementing said different roll stiffnesses of said anti-roll stabilizers of said leading and trailing bogies. 
     
     
         14 . The rail vehicle according to  claim 8 , wherein said anti-roll stabilizers of said leading and trailing bogies have an overall roll stiffness corresponding to an overall roll stiffness of said leading and trailing bogies having identical roll stiffnesses without taking into account an effect of a side wind on the rail vehicle.
