Abstract
The utility model provides an integrated actuating system of pure electric vehicles, belongs to electric motor car power transmission technical field, including driving motor and gearbox, its characterized in that: the clutch comprises a driving motor and a gearbox, and is characterized by further comprising an overrunning clutch connected with the driving motor and the gearbox, wherein an input shaft and an output shaft of the overrunning clutch are respectively connected with an output shaft of the driving motor and an input shaft of the gearbox. The utility model discloses a set up freewheel clutch between driving motor's output shaft and the input shaft of gearbox, not only saved the footboard structure of clutch to eliminate the potential safety hazard that exists because of the huge axial thrust of clutch pedal, can simplify the structure moreover, improve the integrated level of part. Furthermore, the utility model discloses still make full use of driving motor's rotational speed torque is superior to automobile engine's characteristic, combines freewheel clutch's theory of operation, has simplified the separation and reunion process of automobile starting and shifting, has improved electric automobile's driving motor's durability.
Description
Technical field
The utility model relates to the power transmission technology of electronlmobil, the integrated drive system of specifically a kind of pure electric automobile.
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, the huge axial thrust when causing drive motor can not bear the diaphragm clutch pedal fully to step on, the i.e. very big potential safety hazard of the pure electric automobile drive system of existing structure existence.
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 clutch process, the integrated drive system of pure electric automobile that safety is good.
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; Wherein, the input shaft of said overriding clutch is connected with the output shaft of drive motor and the input shaft of change speed gear box respectively with output shaft.
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.
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.In addition, 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
---drive motor, 2---change speed gear box, 3---overriding clutch, 4---support housing among the figure: 1.
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 and overriding clutch 3, wherein, connect through overriding clutch 3 between the input shaft of the output shaft of drive motor 1 and change speed gear box 2; The output shaft of drive motor 1 connects the input shaft of overriding clutch 3; The input shaft of change speed gear box 2 connects the output shaft of overriding clutch 3, 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, 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.
In the technique scheme, overriding clutch 3 is buied for market.
The working process of the utility model is: in the electric automobile during traveling process, chaufeur makes drive motor 1 forward rotation through step on the accelerator, the forward output torque, and 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.
Claims (2)
1. integrated drive system of pure electric automobile; Comprise 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; Wherein, the input shaft of said overriding clutch is connected with the output shaft of drive motor and the input shaft of change speed gear box respectively with output shaft.
2. the integrated drive system of pure electric automobile according to claim 1 is characterized in that: 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.
