The beneficial effects of the utility model are: the speed changer that the utility model adopts two jack shaft coaxially to export achieves the function that system down liter is turned round; two jack shaft can be more steady when high pulling torque exports; and have better protective effect to the life-span of bearing; adopt high-speed electric expreess locomotive and coaxially export, substantially reducing the volume and weight of system.
Accompanying drawing explanation
Fig. 1 is the operation principle schematic diagram of the utility model embodiment.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Be illustrated in figure 1 the pure electric integrated power assembly of one that the present embodiment provides, comprise housing, housing comprises the electric machine casing 1 and case of transmission 2 that are integrated in one, electric machine casing 1 inside is fixed with motor stator component and rotor, rotor is provided with motor shaft, case of transmission 2 mounted inside has transmission input shaft 3, transmission output shaft 4 and drive gear mechanism, described drive gear mechanism comprises radial arrangement in the first jack shaft 5 of transmission output shaft 4 both sides, second jack shaft 6, by first driving gear 7 of spline joint on transmission input shaft 3, the jackshaft drive pinion 8 be meshed with the first driving gear 7 that every root jack shaft assembles, the counter shaft driven gear 9 arranged side by side with jackshaft drive pinion 8 that every root jack shaft is arranged, the first driven gear 10 be meshed with counter shaft driven gear 9 that transmission output shaft 4 is installed.
Motor shaft and transmission input shaft 3 adopt spline joint, first driving gear 7 right-hand member is pressed with left cone bearing 12, the left end of transmission output shaft 4 is rotated by left cone bearing 12 and is assemblied on the first driving gear 7, the right-hand member of transmission output shaft 4 is rotated by right cone bearing 13 and is assemblied on case of transmission 2, transmission output shaft 4 end is connected with ring flange 11, and ring flange 11 is connected to back axle by power transmission shaft.Transmission output shaft 4 is all fixedly installed in axis and radial direction, and transmission output shaft 4 does not float, and can reduce the vibration of output shaft in rotary course, lowers meshing noise.
Every root jack shaft is rotated by bearing and is assemblied on case of transmission 2, because two intermediate shaft structure makes power dividing, gear on the bearing at each jack shaft two ends and jack shaft only bears 1/2nd of total output, gear on transmission input shaft 3 also bears 1/2nd of total output, force direction suffered by such transmission input shaft 3 is contrary, transmission input shaft 3 only bears moment of torsion, does not bear moment of flexure, eliminates and is out of shape by transmission input shaft 3 the transmission gear service life reduction caused.
Be fixed with baffle plate between electric machine casing and case of transmission, this baffle plate is motor transmission supports end cap 14, and motor transmission supports end cap 14 is replaced back end cover for motor and a speed changer front end housing end cap, makes the axiality of whole system more secure.In other embodiments of the present utility model, also back end cover for motor and speed changer front end housing can be made two independently end caps respectively.
Concrete power transmission is crossed and is called: the motor shaft of drive motors passes to transmission input shaft 3, jackshaft drive pinion 8 is passed to through the first driving gear 7, pass to the first driven gear 10 on transmission output shaft 4 by counter shaft driven gear 9 again, exported by ring flange 11.
In other embodiments of the present utility model, described rolling bearing, except above-mentioned cone bearing, can also be cylinder roller bearing, also can be ball bearing etc.
A kind of electric motor car, comprises above-described pure electric integrated power assembly, repeats no more herein.
