Description
Technical field
The utility model relates to the power transmission technology of electronlmobil, specifically a kind of motor integrated drive system of formula pure electric automobile of reversing gear.
Background technology
At present, the drive motor in most of pure electric automobile drive systems is to be connected through diaphragm clutch with change speed gear box, is specially: adopt diaphragm clutch to be connected between the output shaft of drive motor and the input shaft of change speed gear box.Because drive motor and automotive engine difference structurally; Huge axial thrust when causing drive motor can not bear the diaphragm clutch pedal fully to step on; There is very big potential safety hazard in the pure electric automobile drive system that is existing structure; In addition, the gear of existing pure electric automobile change speed gear box is more, has occupied the nervous space of C-class in a large number.
Summary of the invention
The purpose of the utility model be to above-mentioned deficiency provide a kind of simple in structure, parts integrated level high, can simplify the clutch process, practice thrift the automotive interior space, motor that safety is good reverses gear the integrated drive system of formula pure electric automobile.
The utility model is achieved in that and comprises drive motor and change speed gear box; It is characterized in that: also comprise and said drive motor and change speed gear box bonded assembly overriding clutch; Be installed in the magnetic clutch on the overriding clutch; Wherein, The input shaft of said overriding clutch is connected the input shaft of the active friction plate captive joint overriding clutch of said magnetic clutch, the output shaft from movable friction plate captive joint overriding clutch of magnetic clutch respectively with output shaft with the output shaft of drive motor and the input shaft of change speed gear box.
Be fixedly connected with support housing between the housing of said drive motor and the housing of change speed gear box, said overriding clutch is positioned at support housing.
Said change speed gear box is not for there being the change speed gear box that reverses gear.
The utility model is through being provided with overriding clutch between the input shaft of the output shaft of drive motor and change speed gear box; Not only saved the pedal structure of power-transfer clutch; Thereby eliminate the potential safety hazard that the huge axial thrust because of pedal of clutch exists, but and simplified structure, improve the integrated level of parts.The rotational speed and torque that the utility model also makes full use of drive motor is superior to the characteristic of automotive engine, in conjunction with the principle of work of overriding clutch, has simplified the clutch process of vehicle starting and gearshift, has improved the durability of the drive motor of electronlmobil.In addition, the utility model is installed magnetic clutch on overriding clutch, makes when electronlmobil need reverse gear, and only need control magnetic clutch and make overriding clutch locked, and through motor counter-rotating transfer torque, realize reversing.In addition, when chaufeur need be realized motor braking, step on brake, and the locked overriding clutch of control magnetic clutch, at this moment the anti-electric power generation that drags of automobile for car load provides lock torque, has been realized the energy recovery of electronlmobil.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1---drive motor, 2---change speed gear box, 3---overriding clutch, 4---support housing, 5---magnetic clutch, 6---active friction plate of magnetic clutch, 7---magnetic clutch from movable friction plate.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment: of Fig. 1; Comprise drive motor 1, change speed gear box 2, with drive motor 1 and change speed gear box 2 bonded assembly overriding clutchs 3, be installed in the magnetic clutch 5 on the overriding clutch 3, wherein, the input shaft of overriding clutch 3 is connected with the output shaft of drive motor 1 and the input shaft of change speed gear box 2 respectively with output shaft; The input shaft of the active friction plate 6 captive joint overriding clutchs 3 of magnetic clutch; The output shaft from movable friction plate 7 captive joint overriding clutchs 3 of magnetic clutch in addition, is fixedly connected with support housing 4 between the housing of the housing of drive motor 1 and change speed gear box 2; Overriding clutch 3 is positioned at support housing 4, promptly becomes the utility model.
In the technique scheme, support housing 4 fixes the housing of drive motor 1 and the housing of change speed gear box 2, has guaranteed output shaft and the input shaft of change speed gear box 2 and the reliable connection between the overriding clutch 3 of drive motor 1.
In the technique scheme, change speed gear box is not for there being the change speed gear box that reverses gear.The gear that advances that it comprises has 2～3.
In the technique scheme, overriding clutch 3 is market with magnetic clutch 5 and buys.
In the technique scheme, because drive motor 1 is from zero all can output torque to maximum speed of revolution, therefore, the starting of electronlmobil does not need the soft combination of conventional clutch.Simultaneously, because change speed gear box 2 can provide different speed ratios, therefore, can under the condition that guarantees same automotive performance, reduce requirement to drive motor 1.
The working process of the utility model is: in the electric automobile during traveling process; The active friction plate of magnetic clutch 5 with separate from movable friction plate, chaufeur makes drive motor 1 forward rotation through step on the accelerator; The forward output torque; At this moment, overriding clutch 3 combines, and transfers torque to change speed gear box 2.When needing gearshift, chaufeur is release the gas pedal then, and drive motor 1 slows down rapidly; At this moment, since the rotating speed of the output shaft of overriding clutch 3 greater than input shaft rotational speed, therefore; Overriding clutch 3 breaks away from, and drive motor 1 separates with change speed gear box 2, and change speed gear box 2 can carry out gear shift operation.I.e. rotating speed through acceleration pedal controlling and driving motor 1, the combination of the input shaft through overriding clutch 3 and the speed discrepancy controlling and driving motor 1 of output shaft and change speed gear box 2 with separate.
When electronlmobil reversed gear, chaufeur was given the instruction of a contrarotation of motor driver through the operation shifter bar, and simultaneously, control magnetic clutch 5 locked overriding clutchs 3 make that overriding clutch 3 can the back transfer moment of torsion, realize reversing.
At the motor in electric automobile glancing impact, chaufeur is stepped on brake, and control magnetic clutch 5 locked overriding clutchs 3, and at this moment the anti-drive motor 1 that drags of automobile generates electricity, and for car load provides lock torque, has realized the energy recovery of electronlmobil.
