Gear combination, especially for rail vehicles, has summing first gear, planetary second gear working in combination of RPM and torque superimposition, and self-locking step-up third gear

摘要

The gear combination comprises a summing first gear(1), at least one planetary second gear(8,9) working in the combination of RPM and torque superimposition, and a self-locking step-up third gear(14,15) connected to the second drive shaft of the superimposing gear for the purposes of optimum realization of the self-locking and superimposition. The planetary gear may be a spur wheel gear or bevel gear. For traction operation the gear combination has at least one drive shaft on the summing gear, and effects RPM and torque superimposition through the second drive shaft.
