In addition, the actual fabrication process should include three-dimensional space of length, width and depth.
Example one
Referring to fig. 1, fig. 1 is a schematic structural diagram of an automatic gear shifting reducer for an electric vehicle according to the present invention. As shown in fig. 1, the automatic gear shifting reducer for electric vehicles includes a driving shaft 2, a driving gearwheel 5 and a driving pinion 6, wherein the driving gearwheel 5 and the driving pinion 6 are disposed on the driving shaft 2.
The middle shafting can control the speed reducer to automatically switch from a low gear to a high gear and from the high gear to the low gear. The middle shafting comprises jackshaft 3, electro-magnet 7, jackshaft pinion 8, two-way clutch 9, one-way clutch 10, jackshaft gear wheel 11, subassembly 12, the jackshaft driving gear 13 of backing a car, electro-magnet 7, jackshaft pinion 8, two-way clutch 9, one-way clutch 10, jackshaft gear wheel 11, subassembly 12 and the jackshaft driving gear 13 setting of backing a car are in on the jackshaft 3, electro-magnet 7 cooperation two-way clutch 9 control the rotation of jackshaft pinion 8 and jackshaft gear wheel 11, one-way clutch 10 control the rotation of jackshaft gear wheel 11, subassembly 12 control of backing a car the rotation of jackshaft gear wheel 11.
The output shaft system is composed of an output shaft 4 and an output shaft gear 14, and the output shaft gear 14 is arranged on the output shaft 4.
The driving gearwheel 5 is engaged with the intermediate shaft gearwheel 8, the driving gearwheel 6 is engaged with the intermediate shaft gearwheel 11, and the intermediate shaft driving gearwheel 13 is engaged with the output shaft gearwheel 14.
The working principle of the automatic gear shifting speed reducer for the electric vehicle is as follows:
when the electric vehicle runs, the driving shaft 2 is connected with the motor, and the output shaft 4 is connected with the rear axle of the electric vehicle.
When the motor rotates forwards, the driving shaft 2 drives the driving gearwheel 5 and the driving pinion 6 to rotate simultaneously, at the moment, the electromagnet 7 is matched with the bidirectional clutch 9 to control the rotation of the intermediate shaft pinion 8 and the intermediate shaft gearwheel 11, at the moment, the intermediate shaft pinion 8 idles and does not transmit torque, the intermediate shaft gearwheel 11 transmits the torque from the driving shaft 2 to the intermediate shaft 3, the intermediate shaft 3 transmits the torque to the output shaft 4 through the intermediate shaft driving gear 13, and the output shaft 4 transmits the torque to a rear axle of the electric vehicle through the output shaft gear 14. At the moment, the rotation speed of the rear axle is relatively slow, and the transmitted torque is large. The process realizes the forward low-speed running of the electric vehicle.
When the speed of the electric vehicle is increased to a certain speed, the electromagnet 7 cooperates with the two-way clutch 9 to control the rotation of the intermediate shaft pinion gear 8 and the intermediate shaft gearwheel 11, at the moment, the intermediate shaft gearwheel 11 idles and does not transmit torque, the intermediate shaft pinion gear 8 transmits the torque from the driving shaft 2 to the intermediate shaft 3, the intermediate shaft 3 transmits the torque to the output shaft 4 through the intermediate shaft driving gear 13, and the output shaft 4 transmits the torque to the rear axle of the electric vehicle through the output shaft gear 14. At the moment, the rear axle has a higher rotating speed and transmits smaller torque. The low gear is switched to the high gear automatically, and the low gear is mainly switched to the high gear by the movement of the electromagnet 7 and the bidirectional clutch 9.
When the motor reverses, the drive shaft 2 drives the drive gearwheel 5 and the drive pinion 6 rotate simultaneously, at this moment, the electromagnet 7 cooperates with the bidirectional clutch 9 to control the rotation of the intermediate shaft pinion 8, the reversing assembly 12 controls the rotation of the intermediate shaft gearwheel 11, at this moment, the intermediate shaft pinion 8 idles and does not transmit torque, the intermediate shaft gearwheel 11 transmits torque from the drive shaft 2 to the intermediate shaft 3, the intermediate shaft 3 passes through the intermediate shaft driving gear 13 to transmit torque to the output shaft 4, and the output shaft 4 passes through the output shaft gear 14 to transmit torque to the rear axle of the electric vehicle. At the moment, the rotation speed of the rear axle is relatively slow, and the transmitted torque is large. The process realizes the backing operation of the electric vehicle.
