Cross coupling
A cross coupling is a component of traction vehicles , especially the railways and other railways in vehicles with bogies . They were preferably used when operating on winding routes and serve the two bogies to drive through a track curve in a way that is easy to run , as well as to reduce the stress on the track. Their use can reduce the straightening forces and the approach angle when cornering, which means that less wear is achieved on the wheel tires and other components of the drive .
The cross couplings are designed as static or elastic systems. The latter is particularly preferred when the distance between the bogies is large, which means that the model used in the photo has an asymmetrically arranged fork-shaped drawbar and spring cup. The spring cup also takes on the task of compensating for movements in poor track conditions or when entering points. Cross couplings are not primarily used to produce a lurch-free run, as it is z. As in the DR E 15 01 has attempted this task is performed by a roll stabilizer .
A special design of a cross coupling was developed for the RhB Ge 6/6 II and was later used on the SBB Re 6/6 . This is a patent for a cross coupling of three biaxial bogies, which enables a transverse deflection of the middle bogie compared to the RhB Ge 6/6 II locomotive body by up to 180 mm.
