Problems solved by technology

[0002] The wheel drive motor of the existing electric vehicle, the motor rotor will play the role of braking and resistance after the power is turned off. At this time, the vehicle inertial slides to make the speed connection of the wheel hub drive the output shaft, the speed change mechanism and the rotor to rotate, and the motor rotor will be passive. Rotate, so that the vehicle will slow down due to the influence of the magnetic resistance of the rotor and stator, thereby reducing the mileage of the vehicle, increasing energy loss, and accelerating the wear of the entire transmission mechanism

Embodiment 1

[0022] Such as Figure 1 to Figure 6 Shown is the first embodiment of the electric hub clutch mechanism of the present invention, the electric hub clutch mechanism includes a hub ring 20, the hub ring 20 is connected with an end cover 19, and the center of the end cover 19 is provided with a fulcrum hole 24, the fulcrum hole 24 is provided with a fulcrum 2, the motor 1 and the gear box 15 are fixed on the fulcrum 2, the motor 1 is provided with a motor shaft 5, the motor shaft 5 drives the output gear 4 to rotate, and the output The gear 4 is connected to the output shaft 22 through the ratchet 9 to rotate. The output shaft 22 is provided with a slope 3, and the slope 3 cooperates with the moving part 27. The moving part 27 slides to the end cover 19 and connects with it to drive the end cover 19 and the hub ring 20 to rotate.

[0023] After the motor 1 is energized and rotated, the motor shaft gear 26 at the end of the motor shaft 5 drives the output gear 4 to rotate, and th...

Embodiment 2

[0028] Such as Figure 7 to Figure 11 Shown in is the second embodiment of the electric hub clutch mechanism of the present invention, as Figure 11 As shown in , the inner hole of the output shaft 22 is provided with an oblique keyway 36, such as Figure 11 The outer diameter of the slider 37 shown in is provided with an oblique keyway 36, the oblique keyway 36 is a spiral oblique keyway, the slider 37 is set in the inner hole of the output shaft 22 with an oblique keyway, the output shaft 22 and sliding part 37 oblique keyways cooperate with each other.

[0029] When the output shaft 22 is in a static state after the power supply of the motor 1 is turned off, the separation spring 29 pushes away the connecting block 32 and the sliding part 37 to separate, and the sliding part 37 slides to the end position of the output shaft 22. At this time, the connecting block 32 and the sliding part 37 is a separated state, the rotation of the rim 20 will not be transmitted to the outp...

Abstract

The invention belongs to the field of a power transmission technology of an electric vehicle and solves the problems of automatically separating and jointing power and a hub ring of a motor. The invention provides a clutching mechanism of an electric wheel hub. The clutching mechanism comprises the hub ring, wherein the hub ring is connected with an end cover and a supporting shaft hole is formed in the center of the end cover; the supporting shaft hole is provided with a supporting shaft; the supporting shaft is fixedly provided with the motor and a gear box; the motor is provided with an electric shaft and the electric shaft is in transmission joint with an output shaft; the output shaft is provided with an inclined slope and the inclined slope is matched with a movable piece; when the output shaft rotates towards the heading direction of the vehicle, the movable piece is matched with the inclined slope; and the movable piece slides to the end cover and is connected with the end cover to drive the end cover and the hub ring to rotate; and a separation spring is arranged between the movable piece and the end cover.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power transmission. Background technique [0002] The wheel drive motor of the existing electric vehicle, the motor rotor will play the role of braking and resistance after the power is turned off. At this time, the vehicle inertial slides to make the speed connection of the wheel hub drive the output shaft, the speed change mechanism and the rotor to rotate, and the motor rotor will be passive. Rotate, so that the vehicle will slow down due to the influence of the magnetic resistance of the rotor and stator, thereby reducing the mileage of the vehicle, increasing energy loss, and accelerating the wear of the entire transmission mechanism. Contents of the invention [0003] In order to solve the above disadvantages, the purpose of the present invention is to provide a simple structure, which can automatically separate and engage the hub and the output shaft. In this way, after the driv...
