Rail vehicle for use as e.g. shunter, has coupling device arranged between outer drive units and inner drive unit, where coupling device has partial hydraulic, pneumatic, electronic and/or electrical components e.g. steering units

摘要

#CMT# #/CMT# The vehicle (100) has outer drive units (110, 130) and an inner drive unit (120) arranged at a vehicle frame (102) concerning to a longitudinal axis (103). A coupling device (200) is arranged between the drive units i.e. bogies. The coupling device converts transverse displacement of the inner drive unit with respect to a neutral position at the longitudinal axis into steering movement such as rotation movement around a vertical axis, of the outer drive units and vice versa. The coupling device has partial hydraulic, pneumatic, electronic and/or electrical components e.g. steering units. #CMT# : #/CMT# An independent claim is also included for a method for operating a rail vehicle. #CMT#USE : #/CMT# Rail vehicle for use as a maneuvering vehicle i.e. shunter. #CMT#ADVANTAGE : #/CMT# The coupling device is designed such that it requires reduced installation space and enables accurate adjustment of an angle between the outer and inner drive units and a rail track, thus driving the drive units in a simple manner, and reducing noise of the rail vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic top view of a rail vehicle with three drive units in a rail track in an operating condition. 100 : Rail vehicle 102 : Vehicle frame 103 : Longitudinal axis 110, 130 : Outer drive units 120 : Inner drive unit 200 : Coupling device.
