[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
As shown in Figure 1, a kind of used for electric vehicle variable speed drive (VSD) assembly comprises motor 22, gearbox body 16 and gearshift (as shown in Figure 2), it is characterized in that: said motor 22 links with gearbox body 16, is provided with synchronizer assembly in the said gearbox body 16.
Said synchro comprises sliding hub 8, spline housing 14, high speed gear baulk ring 6, low gear baulk ring 11, slide block 9 and wire spring 10.
Except synchronizer assembly, also be provided with input shaft 3, high speed gear soldered tooth 4, high speed gear driving gear 5, high speed gear ring gear 2, low gear soldered tooth 12, low gear driving gear 13 and low gear ring gear 15 in the said gearbox body 16.The inner structure relation of said gearbox body 16 is: said motor 22 is with gearbox body 16 captive joints; The rotor of motor 22 is with input shaft 3 captive joints; High speed gear driving gear 5 is followed high speed gear soldered tooth 4 captive joints, and is contained on the input shaft 3 through the bearing carrier ring in it; High speed gear baulk ring 6 cooperates with high speed gear soldered tooth 4 through the tapering endoporus, and the spline groove on the high speed gear baulk ring 6 matches with slide block 9 simultaneously; The female splines of spline housing 14 matches with male splines on the input shaft 3, and male splines is a free-running fit with the female splines of sliding hub 8, and slide block 9 is sleeved in its groove simultaneously, and wire spring 10 utilizes the elastic force of spring that slide block 9 is pushed up to sliding hub 8; Low gear driving gear 13 is contained on the input shaft 3 through the bearing carrier ring in it with low gear soldered tooth 12 captive joints simultaneously; The internal taper hole of low gear baulk ring 11 matches with low gear soldered tooth 12, and the spline groove on it matches with slide block 9 simultaneously; High speed gear ring gear 2 is meshed with two shaft gears, 1 captive joint and with high speed gear driving gear 5; Low gear ring gear 15 is meshed with two shaft gears, 1 captive joint and with low gear driving gear 13.
As shown in Figure 2, said gearshift comprises shifting fork pin 17, shift fork pivoted arm 18, declutch shift shaft 19, shift fork 20, set pin 7 and last undersetting 21, and said shift fork pivoted arm 18 is with declutch shift shaft 19 captive joints; Declutch shift shaft 19 is sleeved on the undersetting 21, is free-running fit between them; Shift fork 20 is fixedly mounted on the declutch shift shaft 19 through set pin 7; Shifting fork pin 17 is fixedly mounted on the shift fork 20; Shifting fork pin 17 is inserted in the annular groove of sliding hub 8, is free-running fit between the two.
The principle of work of the utility model:
1, when shift fork pivoted arm 18 during at Neutral Position; Sliding hub 8 mediates under the effect of shifting fork pin 17, neither engages with high speed gear soldered tooth 4, does not also engage with low gear soldered tooth 12; Rotor drives input shaft 3, spline housing 14, sliding hub 8 rotations, belongs to motor idle running neutral state.
2, unclamp car accelerator; Motor cuts off power naturally; The rotor of motor is rotating according to its inertia, and stir gear shifting handle this moment, under the effect of synchronizer assembly; Make sliding hub 8 synchronous with high velocity engagement tooth 4 or low speed soldered tooth 12, realize from a high speed to low speed, from low speed to high speed or the conversion freely of neutral gear.
3, to realize under the various situations gear shift freely; Its condition precedent is that motor outage back in service (unclamping throttle) is the rotation freely under the unpowered driving; Friction force after the conical surface between baulk ring in the synchronizer assembly (high speed gear baulk ring 6 or low gear baulk ring 11) and the soldered tooth (high speed gear soldered tooth 4 or low gear soldered tooth 12) combines is enough to make sliding hub 8 synchronous with high speed gear soldered tooth 4 or low gear soldered tooth 12, reaches the effects equivalent of being cut off power by power-transfer clutch with this.
Then the present technique scheme implementation finishes.
