Abstract
The utility model relates to a driving device for locomotives, in particular to a suspended driving device, which comprises a traction motor and a gearbox. A driving gear and a driven gear in mesh are arranged in the gearbox, the driven gear is connected with a wheel pair, a hollow shaft is arranged in the driving gear, a middle shaft arranged in the hollow shaft penetrates through the hollow shaft, one end of the middle shaft is connected with the driving gear through a coupler, and the other end of the middle shaft is connected with the motor through a coupler. The driving device for the locomotives is simple in structure and convenient for overhaul and maintenance.
Description
Technical field
The utility model relates to a kind of locomotive drive device, particularly a kind of suspension type actuating device.
Background technology
Traction electric machine frame suspension type drive system is widely used on express locomotive and the motor train unit, and its principal feature is that traction electric machine is fixedly mounted on the truck frame, makes the weight of traction electric machine belong to the locomotive sprung weight.Traction electric machine and wheel between need with adapting to respectively to the mechanisms such as elastic coupling that move as middle hookup and transfer torque.The frame suspension type actuating device that present domestic electric locomotive adopts mainly contains the motor-hollow axle actuating device and takes turns the hollow shaft actuating device.
The characteristics of motor-hollow axle actuating device are that the pivot of motor is a hollow structure, and traction gearbox is bearing on the axletree, and driven gear also is assemblied on the axletree.During traction electric machine work, the moment of torsion of motor-hollow axle, through the moving torsion bar of the interior external gear connecting band of motor non-transmision end, the driving end of torsion bar reaches miniature gears, big gear wheel by elastic coupling with moment of torsion, thus drive wheel is to moving ahead.
Wheel is that big gear wheel is bearing on the hollow shaft sleeve by antifriction-bearing box to the characteristics of hollow shaft actuating device; And hollow shaft sleeve is fastened on the motor body seat; In hollow shaft sleeve, run through a hollow shaft; And axletree places hollow shaft, and an end of hollow shaft links to each other with big gear wheel through terminal pad, six connecting rod elastic elements, and the other end passes through drive plate, six connecting rod elastic elements and wheel to being connected.
These two kinds of frame suspension type actuating device mechanisms are complicated, are unfavorable for the repair and maintenance of locomotive.
Summary of the invention
The utility model is not enough to prior art, and a kind of locomotive drive device is provided, and is simple in structure, and easy access is safeguarded.
The technical scheme of the utility model is that a kind of locomotive drive device comprises traction electric machine and gear case; Establish intermeshing driving gear and driven gear in the gear case; Driven gear with the wheel to being connected, establish hollow shaft in the said driving gear, and in hollow shaft, have tween drive shaft to pass this hollow shaft; Said tween drive shaft one end links to each other with driving gear through coupler, and the tween drive shaft other end links to each other with motor through coupler.
Said coupler is a diaphragm coupling.
Tractive motor hanging is on truck frame, and traction electric machine directly is connected with tween drive shaft through diaphragm coupling.Tween drive shaft passes hollow shaft and is connected with driving gear through diaphragm coupling.The engagement of driving gear and driven gear, driven gear and wheel are to being connected, thereby right driving is taken turns in realization.
Know that by above the utility model is as a kind of locomotive drive device, the transmission adopted diaphragm coupling, space hold is little, is prone to balance, need lubricate,, easy accessibility strong and simple in structure to compatible with environment, reliable operation, noiselessness; Driving gear adopts the hollow shaft design, and traction electric machine directly is connected with tween drive shaft through diaphragm coupling, and tween drive shaft passes hollow shaft and is connected with driving gear through diaphragm coupling, thereby improves the displacement compensation capability of coupler.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1, a kind of locomotive drive device comprises traction electric machine 1 and gear case; Establish intermeshing driving gear 3 and driven gear 8 in the gear case; Driven gear 8 is connected 7 with wheel, establishes hollow shaft 5 in the driving gear 3, and in hollow shaft 5, has tween drive shaft 6 to pass this hollow shaft 5; Tween drive shaft 6 one ends link to each other with driving gear 3 through diaphragm coupling 4, and tween drive shaft 6 other ends link to each other with motor 1 through diaphragm coupling 2.
