The working principle of the automatic transmission of the electric automobile with the brushless wire control centrifugal ball arm joint device is further described by combining the embodiment as follows:
during first gear transmission, the electromagnetic coil in the electromagnet 10h is powered off, the drive-by-wire drive disk 10g is engaged with the stop disk 10f under the action of the elastic force of the pre-pressing spring 10i, the stop disk 10f is fixed on the shell and is not moved, so that the friction force between the drive-by-wire drive disk 10g and the stop disk 10f after engagement makes the rotation speed of the drive-by-wire drive disk 10g and the hollow wheel disk 10j of the centrifugal ball arm zero, the centrifugal ball arm 10l and the centrifugal ball 10m are folded inwards under the twisting action of the return spring 10p of the centrifugal ball arm, so that the brushless drive-by-wire centrifugal ball arm engagement device 10 does not transmit power, at the moment, the torque of the motor 100 is transmitted to the sun gear 3 through the input shaft 1, the sun gear 3 transmits the power to the rear planet carrier 6 fixedly connected with the planet gear shaft 5 through the normally engaged planet gear 4, the rear planet carrier 6 is fixedly installed on the middle shaft neck of the output shaft 2 by means of a shaft shoulder and a retaining ring through the center through hole thereof, therefore, the input shaft 1 transmits the torque to the output shaft 2.
During the second gear transmission, the electromagnetic coil in the electromagnet 10h is electrified, the brushless wire-controlled centrifugal ball arm joint device 10 works, after the electromagnetic coil of the electromagnet 10h is electrified, the electromagnetic attraction force generated by the electromagnet 10h is transmitted to the wire-controlled driving disk 10g through the magnetic conduction force transmission disk 10q, the wire-controlled driving disk 10g overcomes the elastic force of the pre-pressing spring 10i and moves towards the electromagnet 10h, so that the friction driving end surface 10ga of the wire-controlled driving disk 10g is jointed with one end surface of the magnetic conduction force transmission disk 10q, the centrifugal ball arm hollow wheel disk 10j is driven to rotate under the action of the friction force generated by the joint of the two, the centrifugal ball arm hollow wheel disk 10j drives each centrifugal ball arm 10l to rotate, meanwhile, under the action of the centrifugal force, each centrifugal ball arm 10l stretches outwards around the centrifugal ball arm pin 10k, so that one end provided with the centrifugal ball 10r drives the centrifugal ball 10m to move outwards along the smooth surface 10ca of the thrust pressure disk 10c to make a circle, therefore, the centrifugal ball arm 10l and the centrifugal ball 10m generate centrifugal force, the component force of the centrifugal force in the direction of the central shaft of the centrifugal ball arm hollow wheel disc 10j pushes the thrust pressure plate 10c to generate axial movement away from the centrifugal ball arm hollow wheel disc 10j, so that the thrust pressure plate 10c compresses each externally-provided splined grooved steel sheet 10b and each internally-provided splined grooved friction sheet 10a mutually, and the driven internally-splined hub 10d and the input shaft 1 synchronously rotate by means of the friction force between each externally-provided splined steel sheet 10b and each internally-splined grooved friction sheet 10a, so that the torque input by the input shaft 1 is transmitted to the output shaft 2.
The transmission route of the first gear is as follows: the electromagnetic coil of the electromagnet 10h is powered off, the driven internal spline hub 10d freely rotates relative to the input shaft 1, the torque of the motor 100 is transmitted to the sun wheel 3 through the input shaft 1, the inner gear ring 7 is fixedly arranged on the rear shell 31A and is fixed, the planet wheel 4 is arranged on the planet wheel shaft 5 in a rolling way through a sliding bush, one end of the planet wheel shaft 5 is fixedly connected with the rear planet carrier 6, the planet wheel 4 is constantly engaged with the sun wheel 3 and the inner gear ring 7, so the torque input by the input shaft 1 is further transmitted to the rear planet carrier 6, and the rear planet carrier 6 is fixedly arranged on the middle shaft neck of the output shaft 2 through the central through hole of the rear planet carrier 6, so the input shaft 1 transmits the torque to the output shaft 2, and the first-gear transmission is realized.
The transmission route of the second gear is as follows: the electromagnetic coil of the electromagnet 10h is electrified, the driven internal spline hub 10d rotates synchronously with the input shaft 1, the torque of the motor 100 is transmitted to the input shaft 1 through the spline, and because the driven internal spline hub 10d rotates synchronously with the input shaft 1, the torque of the motor 100 is transmitted to the driven internal spline hub 10d, and because the driven internal spline hub 10d is fixedly connected with the rear planet carrier 6 through the planet wheel shaft 5, the rear planet carrier 6 is fixedly arranged on the middle shaft neck of the output shaft 2 through the central through hole thereof, the torque of the motor 100 is transmitted to the output shaft 2, and therefore, the two-gear transmission is realized.
The transmission route of the reverse gear is as follows: the electromagnetic coil of the electromagnet 10h is powered off, the motor 100 rotates reversely, the driven internal spline hub 10d rotates freely relative to the input shaft 1, the torque of the motor 100 is transmitted to the sun gear 3 through the input shaft 1, the inner gear ring 7 is fixedly arranged on the rear shell 31A and is fixed, the planet gear 4 is arranged on the planet gear shaft 5 in a rolling mode through a sliding bush, one end of the planet gear shaft 5 is fixedly connected with the rear planet carrier 6, the planet gear 4 is constantly meshed with the sun gear 3 and the inner gear ring 7, so that the torque input by the input shaft 1 is further transmitted to the rear planet carrier 6, and the rear planet carrier 6 is fixedly arranged on a middle shaft neck of the output shaft 2 through a central through hole thereof, so that the input shaft 1 transmits the torque to the output shaft 2, and reverse gear transmission is realized.
Neutral position: the motor 100 is stalled and neutral is achieved.
