Torsion coupling device 20 or 30 is pre-assembled on the shaft end freely of output shaft 26 and input shaft 36 respectively as the coupling device halfbody of two torsion coupling device 1.At this, each of two preassembled coupling device halfbodies comprises adpting flange 21 or 31, elastic coupling element 22 or 32 and split 41 or 42.
Power assembly system in running position is shown in figs. 3 and 4, and in this running position, output shaft 26 and input shaft 36 are arranged coaxially with each other.At this, two coupling device halfbodies of two torsion coupling device 1 are connected to each other as follows, that is, make two splits 41 and 42 twist each other to connect, thus make the driving torque of driver 2 can pass through two torsion coupling device 1 and be delivered on axletree 4 and rail wheel 5 by axle toothing roller box 3.Do not illustrate in the reduced graph of Fig. 3 and Fig. 4 for two splits 41 and 42 being twisted each other the cooperation screw 43 connect.
That is, Fig. 3 and Fig. 4 illustrates and states method step y on the implementation) and z) after power assembly system, namely, axle toothing roller box 3 is at method step y) in be pivoted to running position from rigging position, and after this at method step z) in two splits 41 and 42 are connected to each other or twist and connect.
Axle toothing roller box 3 is supported on bogie 8 by torque support 7 in running position.Torque support 7 is mainly used in holding the driving torque be delivered to by two torsion coupling device 1 by driver 2 on axle toothing roller box 3.
In addition, Fig. 3 illustrates the spin axis 44 of the output shaft 26 of driver 2, and this spin axis 44 is arranged substantially in parallel with the spin axis 6 of axletree 4.In theory ideally, the spin axis 44 of output shaft 26 forms the spin axis of the input shaft 36 of axle toothing roller box 3 simultaneously.But in practice, this is situation about occurring the short time travelling run duration at the most.First, when assembling, the output shaft 26 of driver has had vertical skew relative to the input shaft 36 of axle toothing roller box 3, and this Offset portion is caused by structure and part is caused by the manufacturing tolerances on bogie, on a drive and/or on gear-box.Secondly, by especially obtaining axis other between output shaft 26 and input shaft 36, radial and/or angled skew in the relative movement travelling run duration axle toothing roller box 3 relative to driver 2 enforcement be fastened on bogie 8.Particularly by without occur during upper and lower spring (the Ein-und Ausfedern) of spring-loaded axletree 4 relatively by spring-loaded bogie 8 and the spring movement stood together at least partly by axle toothing roller box 3 obtains mentioned relative movement.
Described two torsion coupling devices 1 can compensate the described skew between output shaft 26 and input shaft 36, and however still reliably can transmit driving torque.Two Flexible spacecraft planes of two torsion coupling device 1 are responsible for making the bearing on the bearing of attaching troops to a unit being applied in driver 2 and axle toothing roller box 3 that caused by the skew of shaft end to minimize.
