Rear engine is minor axis derailleur for passenger train

The utility mode relates to a rear engine is minor axis derailleur for passenger train has solved current rear engine passenger train and has kept off the problem that the operating mode can't be satisfied in the derailleur existence with five. Including horizontal casing, be provided with in the horizontal casing reverse gear, six go forward and keep off and driven input shaft of coaxial line and output shafts, all be provided with the copper centering block on the shift fork that keeps off that gos forward, go forward keep off 2 6 keep off the gear and be the helical gear, and all be provided with the synchronous ware of short stroke catch formula base steel sprayed molybdenum on the helical gear. The utility model has the advantages of reasonable design reliably, satisfy engine maximum power 140~180PS, rated torque 750Nm, rated revolution 2600rpm, 6 keep off velocity ratios 0.786, 1 keeps off velocity ratio 5.897, and then satisfies rear engine to the operation requirement of transmission shaft short dista
