Description
Technical field
The utility model belongs to electric powered motor transfer device scope, particularly a kind of used for electric vehicle variable-speed drive.
Background technology
Electronlmobil is the focus of our times various countries research, is the important channel that solves energy shock and environmental pollution.Electronlmobil has higher requirements to the drive motor performance, requires motor at Heng Zhuanjuqu higher instantaneous torque to be provided, and at Heng Gongshuaiqu higher running velocity is provided, and could satisfy the requirement of the vehicle performances such as maximum speed, climbing and acceleration of vehicle like this.Yet, on electronlmobil, generally all adopt one-level fixed speed ratio retarder, make electronlmobil that a gear is only arranged like this, motor in electric automobile often is operated in the low efficiency district, has both wasted electric energy and continual mileage is reduced, and has improved the requirement to traction electric machine again.If on electronlmobil, adopt multi-shifting speed variator, then can give full play to the preceence of electronlmobil, reduce the requirement of electronlmobil to electrokinetic cell and traction electric machine.
The utility model is applied to electronlmobil with change-speed box in the orthodox car transmission system and power-transfer clutch, helps improving the performance of electronlmobil.
The utility model content
The purpose of the utility model is generally to adopt one-level fixed speed ratio retarder to existing electronlmobil; Make electronlmobil that a gear is only arranged like this; Motor in electric automobile often is operated in the low efficiency district, has both wasted electric energy and continual mileage is reduced, and has improved the deficiency to the requirement of traction electric machine again; And a kind of used for electric vehicle variable-speed drive is provided; It is characterized in that the output shaft of the motor of this variable-speed drive links to each other through spline with adapter sleeve, center bolt is axially fixed in adapter sleeve on the motor output shaft; Flywheel links to each other with adapter sleeve through the 3rd bolt; Clutch assembly is between change speed gear box and motor, and clutch cover back plate is connected with flywheel through second bolt, and on gear-box axle, the gear-box axle right-hand member is supported in the adapter sleeve endoporus through bearing clutch driven disc through spline housing, and the bearing two ends are spacing through collar; Gear-box case connects into an integral body with electric machine casing through being connected shell.
Said clutch driven disc and platen are fixed together.
One end of said connection shell is connected with motor housing with bolt, and the other end is connected with gear-box case with first bolt.
The beneficial effect of the utility model is that electronlmobil adopts multi-shifting speed variator, then can give full play to the preceence of electronlmobil, reduces electronlmobil to electrokinetic cell and traction electric machine requirement.The utility model is applied to electronlmobil with change-speed box in the orthodox car transmission system and power-transfer clutch simultaneously, helps improving the performance of electronlmobil.
Description of drawings
Fig. 1 is a used for electric vehicle variable-speed drive structural representation.
The specific embodiment
The utility model provides a kind of used for electric vehicle variable-speed drive, explains below in conjunction with accompanying drawing.
Shown in Figure 1 is used for electric vehicle variable-speed drive structural representation.Among the figure, the output shaft 17 of the motor 18 of variable-speed drive and adapter sleeve 2 link to each other through spline, and center bolt 15 is axially fixed in adapter sleeve 2 on the motor output shaft 17; Flywheel 3 links to each other with adapter sleeve 2 through first bolt 14; Clutch assembly 7 is between change speed gear box 9 and motor 18, and clutch cover back plate is connected with flywheel 3 through second bolt 13, and on gear-box axle 8, clutch driven disc 4 is fixed together with platen 5 clutch driven disc 4 through spline housing; Gear-box axle 8 right-hand members are supported in adapter sleeve 2 endoporus through bearing 6, and bearing 6 two ends are spacing through collar 14; To connect into an integral body be exactly that an end that connects shell 1 is connected with motor housing 16 with bolt through being connected shell 1 for gear-box case 10 and motor casing 16 bodies, and the other end is connected with gear-box case 10 with first bolt 11.
Its principle of work is: the torque of output is passed to adapter sleeve 2 through the spline on the output shaft 17 during motor 18 work; Adapter sleeve 2 is passed to flywheel 3 through first bolt 14 with torque; Because clutch cover and plate assembly is pressed to clutch plate 4 on flywheel 3 end faces through second bolt 13; Just set up the necessary thrust of frictional transmission like this between platen in clutch cover and plate assembly 5, clutch plate 4 and the flywheel 5; Through frictional transmission flywheel torque is passed to clutch plate 4, clutch plate 4 is given transmission shaft 8 through the spline wherein with transmission of torque, thereby has realized the reliable delivery of torque from the motor to the change-speed box.When needs interrupted transmission of power, the holddown spring separation of depressing on the clutch cover and plate assembly through steering unit referred to that removal acts on the thrust on the platen, thereby interrupts the transmission of power.
Can find out that from said structure the electronlmobil of the utility model adopts multi-shifting speed variator, can give full play to the preceence of electronlmobil, reduce electronlmobil electrokinetic cell and traction electric machine requirement.The utility model is applied to electronlmobil with change-speed box in the orthodox car transmission system and power-transfer clutch simultaneously, helps improving the performance of electronlmobil.
