Under the action of push to the right, be power discrete state between clutch 231 and planet carrier 2333 at this time, and clutch 231
The control of pawl 232 is depressed state, makes ring gear 2332 and wheel by the interior side contacts of the high plane and pawl 232 of ramp structure
It is power discrete state between hub 4, power is entered by free wheel base at this time, and ring gear is transferred to by the first one-way clutch
2332, rotary power is passed to planetary gear train 233 and carries out deceleration transmission by ring gear 2332, then single through second by planet carrier 2333
It is exported to clutch to wheel hub 4, with the vehicle wheel rotation that runner hub 4 connects, which is low or first gear, power transmission line such as Fig. 9
In arrow shown in, the state of pawl 232 is as indicated by 10.
When the centre position of the cam surface of cam chair and straight-bar contact, cam chair by straight-bar push control set 234 to
The planet carrier 2333 in left side is close, is still at this time discrete state between clutch 231 and planet carrier 2333, but in clutch
During 231 are moved to the left, the outer ring of clutch 231 is with the position of 232 interior side contacts of pawl by high plane through ramp structure
It is converted into low level face, the inside of pawl 232 loses the limitation of clutch 231, is bounced under the action of itself compression spring, ring gear
It is transformed to unidirectional power drive state between 2332 and wheel hub 4, at this point, power is entered by free wheel base, is directly passed by pawl 232
It is handed to ring gear 2332 and is finally transferred to the output of wheel hub 4, it is direct gear, wheel to drive the vehicle wheel rotation being connect with wheel hub 4, the gear
The rotating speed of hub 4 is more than the rotating speed of planet carrier 2333, and the second one-way clutch is exceeded, the arrow in power transmission line such as Figure 11
Shown, the state of pawl 232 is as shown in figure 12.
When a high position for the cam surface of cam chair is contacted with straight-bar, cam chair continue through straight-bar bar push control cover 234 to
The planet carrier 2333 in left side is close, bonding state will be transformed between clutch 231 and planet carrier 2333, at this time pawl 232
Inside keeps contacting with the low level face of 231 outer ring of clutch, and state is transmitted for unidirectional power between ring gear 2332 and wheel hub 4,
At this point, power is entered by free wheel base, planet carrier 2333 is transferred to by clutch 231, rotary power is passed to by planet carrier 2333
Planetary gear train 233 carries out step-up drive, is then exported to wheel hub 4 by pawl 232 by ring gear 2332, is connected with runner hub 4
Vehicle wheel rotation, the gear keep off for speedup, and the rotating speed of wheel hub 4 and ring gear 2332 is more than the rotating speed of free wheel base, the first one-way clutch
Device is exceeded, and for power transmission line as shown in the arrow in Figure 13, the state of pawl 232 is still as shown in figure 14.
Wherein, further include velocity measurement mechanisms for measuring 4 rotating speed of wheel hub.
Specifically, being provided with velocity measurement mechanisms on 4 component of wheel hub, can be used for measuring being turn-taked within the unit interval of wheel hub 4
Number, and then obtain the travel speed of wheel.
More specifically, velocity measurement mechanisms are connect with integrated circuit board, can real time speed information be passed to integrated circuit board
Card, the integrated circuit board clamping collection of letters is judged after ceasing and sends control information to motor, controls the rotation time of motor, in turn
The rotation angle of rotary drive seat 221 is controlled, and then realizes the auto-changing of gear.
Wherein, velocity measurement mechanisms include the second magnetic patch 41 being arranged on wheel hub 4 and the fixed setting of 4 component of relativeatoeterahub
The second hall sensing part.
Specifically, the second hall sensing part is arranged on the bearing being fixedly installed with hub spindle, the fixation of the second magnetic patch 41 is set
It sets on wheel hub 4, the second magnetic patch 41 follows the rotation of wheel hub 4 and rotates, when the second magnetic patch 41 passes through the second hall sensing part
When induction zone, the number of turns recorded is a circle.
Wherein, clutch 231 and control set 234 between be provided with third spring 236, for cushioning control set 234 drive from
The action that clutch 231 moves.
Specifically, as shown in Fig. 5 to Figure 16, third spring 236 is mounted on control by gasket 2341 and clamp spring 2342 and covers
Between 234 and clutch 231, when control set 234 is moved along the axial direction of hub spindle, first third spring 236 can be driven to stretch
Or compression just starts what drive was connect with third spring 236 after reaching the elastically-deformable maximum value of third spring 236
Clutch 231 is moved along the axial direction of hub spindle.Therefore, third spring 236 drives clutch 231 to move in control set 234
Action in play cushioning effect, avoid the actuation clamping stagnation between clutch 231 and control set 234, and burn electricity
Machine.
More specifically, there are gap between 234 end faces of gasket 2341 and control set, then the active force of third spring 236 is not
It directly acts on control set 234, does not then interfere with control set 234 when clutch 231 rotates, largely avoid control set
Friction between 234 and clutch 231 and be worn.
