The direct drive clutch assembly and the deceleration clutch assembly are respectively located on both sides of the hub cover 10-1, and the hub cover 10-1 is rigidly connected to the hub 10-2. There are several (more than or equal to one) first driving clutch plates 1-2 and first driven clutch plates 1-3 in sequence inside the direct drive clutch assembly, and the first driving clutch plates 1-2 and the first driven clutch plates 1-3 are arranged in a staggered manner, that is, a first active clutch plate 1-2, followed by a first driven clutch plate 1-3, and then a first active clutch plate 1-2, arranged in sequence. The staggered arrangement of several first driving clutch plates 1-2 and first driven clutch plates 1-3 constitutes the whole clutch plate inside the direct drive clutch assembly. When the direct drive clutch assembly is pressed by the first spring 1-6 to press the clutch plate as a whole, the driving force of the motor is transmitted to the hub 10-2 through the motor drive shaft sleeve 2-1 through the driving wheel 1-4; and when the direct drive The clutch assembly is not pressed, and the first driving wheel clutch plate 1-2 is separated from the first driven wheel clutch plate 1-3, and the driving wheel 1-4 is in an idling state.

Since the center of the axial drive gear 8-5 is fixed on the outer cover 8-1 of the reducer, the axial drive gear 8-5 only performs rotational movement under the driving force, therefore, the axial movement control part 6-2 is affected by the transmission thread while moving horizontally. The fourth ball bearing 6-3 is externally nested on one side of the axial movement control part 6-2, and the ball bearing 6-3 is embedded in the deceleration clutch push plate 6-1, when the axial movement control part 6-2 is When the force moves horizontally, the deceleration clutch push plate 6-1 then moves axially through the retaining ring (the first retaining ring 6-4 and the second retaining ring 6-5). The planetary gear system assembly includes three planetary gears 5-1, a planetary gear system ring gear 8-2 fixed on the outer cover, a planetary gear seat 4-1 and a drive motor rotating shaft sleeve 2-1 with gears. The three planetary gears 5-1 generally rotate around the central gear like planets, and the three planetary gears 5-1 are evenly distributed on the circumference at intervals of 120 degrees.

The outer edge of each second driving wheel clutch plate 4-5 has a rotationally symmetrical protrusion, which is embedded in the protruding groove of the planetary gear seat 4-1, and is driven by the planetary gear seat 4-1, and each second driven wheel The protrusion on the inner edge of the clutch plate 4-6 is then embedded in the groove of the hub cover 10-1, thereby being driven. The reduction clutch assembly is regulated by the reduction clutch control system assembly located adjacent thereto.

The present invention calculates the driving speed according to the vehicle speed sensor, and uses it as the basis for judging the mutual switching between the direct drive clutch assembly and the deceleration clutch assembly. When the car is just starting or under high load conditions, the driving speed is zero or low, so that the pressing force of the inner spring 1-6 of the direct drive clutch assembly on the clutch disc is invalidated by the thrust of the clutch pressure plate 1-5, and the deceleration clutch The assembly is closed by pressing, and the drive motor rotor 2-7 rotates the shaft sleeve 2-1 through the motor, and transmits relatively high torque to the hub 10-12 through the planetary gear system assembly, thereby making the vehicle drive smoother.
