It can surmount.
The present invention will be further described in the following embodiments：
Embodiment 1：
This is that speed changer enters a case where gear falls back on neutral gear with a gear from neutral gear.
In Fig. 2, the 6 vacancy locking ball 604 of gearshift controller in gear (gear Z1) gearshift is located at axis 02
In location hole, gearshift controller 6 is located at the centre position of gear Z1 and gear Z3, i.e., one gear gearshift and three gear shifts at this time
The vacancy of device, control ring 603 are locked up the locking of steel ball 606 with spline housing 605 and cannot relatively move, controllable overrunning clutch C1
Inner ring 105, C3 inner ring 305 be freely rotated between respective outer ring and axis 02.Assuming that enter a gear, shift fork 8 at this time
Gearshift controller 6 is driven to be moved to gear Z1, locking ball 604 exits the vacancy location hole of axis 02.When jaw clutch Y1 is complete
When full combination, 606 position of locking steel ball is overlapped with the locking location hole on axis 02, and gear (gear Z1) gearshift enters preparation
Position, at this point, C1 inner rings 105 are rotated synchronously with axis 02.When shift fork 8 drives gearshift controller 6 to continue to gear Z1 movements, spline housing
605 are stopped that locking steel ball 606 is pressed into the locking location hole on axis 02, control ring 603 by stopping, control ring 603 by C1 inner rings 105
With the latch-release of spline housing 605, spline housing 605 is locked with axis 02.Shift fork 8 drives control ring 603 to continue to move forward, and oppresses wedge
Block controls spring 102, and voussoir 103 is made to rotate, and voussoir 103 contacts the outer rings C1 101, and C1 Internal and external cycles are by wedging.A gear (gear at this time
Z1) gearshift enters working position, and power passes to axis 02 through Z1 and exports.Shift fork 8 drives control ring 603 to continue to move forward, latch
601 are inserted into Z1 lateral grooves, make C1 lockings and cannot surmount；Locking ball 607 shown in Fig. 3 enters on spline housing 606 at this time
Surmount locking location hole, position locking of the control ring 603 on spline housing 605, gear (gear Z1) gearshift enters a gear
Surmount locking position, speed changer enters a gear.
Assuming that speed changer will be exited from a gear (gear Z1) now, shift fork 8 moves after driving control ring 603, locking ball 607
605 upper Positioning holes of spline housing are exited, latch 601 exits gear Z1 lateral grooves, and gear (gear Z1) gearshift exits super
More locking position reaches working position.Shift fork 8 moves after driving control ring 603 to continue, and gear (gear Z1) gearshift, which reaches, to be prepared
Position, locking steel ball 606 exit the location hole on axis 02, and spline housing 605 is locked with control ring 603；Control ring 603 is no longer at this time
Oppress voussoir and control spring 102, but voussoir 103 can not be detached by wedging force effect with the outer rings C1 101, C1 Internal and external cycles still by
Voussoir wedging, speed changer is still with gear (gear Z1) passing power.Shift fork 8 moves after driving gearshift controller 6 to continue, until dental inlay
Clutch Y1 is completely disengaged, and gear Z1 loses passing power ability, and C1 Internal and external cycles lose wedging power, and voussoir 103 is by preloading spring
104 effects reset, and locking ball 604 enters the vacancy location hole on axis 02, and gear (gear Z1) gearshift reaches vacancy, becomes
Fast device exits a gear.
Embodiment 2：
This is the case where low gear enters high gear and high gear enters low gear.
When speed changer is in neutral gear, each gear gearshift is all located at vacancy, needs to enter a gear (tooth from neutral gear at this time
Take turns Z1).Shift fork 8 drives gear (gear Z1) gearshift to enter to prepare position, then arrive working position, then to surmounting locking position, complete
At neutral gear to the conversion of a gear (gear Z1).
When needing to enter two gears (gear Z2) from a gear (gear Z1)（Bottom gear enters top gear）, the drive of shift fork 8 one
Gear (gear Z1) gearshift falls back on working position from locking position is surmounted.Meanwhile shift fork 9 drive two gear (gear Z2) gearshifts from
Vacancy, which enters, prepares position, and shift fork 9 drives two gear (gear Z2) gearshifts to continue to move to Z2, into working position.A gear at this time
(gear Z1), two gear (gear Z2) gearshifts are in working position, because gear Z2 rotating speeds are more than gear Z1 rotating speeds, two gear (teeth
Take turns Z2) the controllable overrunning clutch Internal and external cycle of gearshift is by wedging, and power is transmitted to axis 02 via gear Z2 and exports, a gear
The controllable overrunning clutch of (gear Z1) gearshift, which is in, surmounts state.Shift fork 8 drive one gear (gear Z1) gearshift from
Working position, which is fallen back on, prepares position, and under the effect of preloading spring 104, voussoir 103 is detached from the outer rings C1 101 and resets, the separated states of C1；It dials
Fork 8 continues that gear (gear Z1) gearshift is driven to return to vacancy, exits a gear.Meanwhile shift fork 9 drives two gear gearshifts again
It is moved to Z2, surmounts locking position into two gears, complete a gear to two gear alternatings.
Similarly, two gears to three gears, three gears to four gears and so on.
When speed changer needs to enter a gear (gear Z1) from two gears (gear Z2)（Top gear enters bottom gear）, two gears
(gear Z2) gearshift falls back on working position under the drive of shift fork 9 from locking position is surmounted.Meanwhile one keeps off (gear Z1) shift dress
It sets to enter from vacancy under the drive of shift fork 8 and prepares position, enter back into working position.At this point, a gear (gear Z1), two gears (gear Z2) change
Blocking means are in working position, and because Z2 rotating speeds are more than Z1 rotating speeds, power is transmitted by Z2.When shift fork 9 drives two gears (gear Z2) to change
When blocking means fall back on preparation position from working position, the controllable overrunning clutch voussoir of two gear (gear Z2) gearshifts is by wedging masterpiece
With the Internal and external cycle of still wedging freewheel clutch, power is still transmitted by Z2；When two gear (gear Z2) gearshifts are moved back from position is prepared
When entering vacancy, the jaw clutch separation of two gear (gear Z2) gearshifts, Z2 loses passing power ability, and power is via gear
Z1 is transmitted to axis 02.Then, shift fork 8 drives gear (gear Z1) gearshift to enter a gear into locking position, speed changer is surmounted.
Similarly, four gears to three gears, three gears to two gears and so on.
Embodiment 3：
This be engine occur it is anti-when dragging the case where.
When automobile downhill or when by inertia traveling, engine is it is possible that anti-the case where dragging, at this time residing for speed changer
The driven gear of gear（Such as Z1）Rotating speed is less than driven shaft（02）Rotating speed, speed changer will appear transmit reverse power the case where,
Reverse power is transmitted by the latch of residing gear.
In this case, when speed changer needs to enter high gear from low-grade location, a such as gear (gear Z1) enters two gear (gears
Z2), after the two gear position (gear Z2) gearshifts enter working position, when gear Z2 rotating speeds are more than 02 rotating speed of axis, speed changer turns
To transmit positive power；When gear Z2 rotating speeds are still less than 02 rotating speed of axis, speed changer is in art skating state, neither transmits
Positive power does not also transmit reverse power；Only after two gear (gear Z2) gearshifts enter and surmount locking position, just by gear
Z2 continues to transmit reverse power.
When speed changer needs to enter low gear from high tap position, and such as two gears (gear Z2) enter a gear (gear Z1), because of tooth
It takes turns Z1 rotating speeds and is less than gear Z2 rotating speeds, gear Z1 is certainly less than 02 rotating speed of axis, when two gear (gear Z2) gearshifts are from surmounting lock
When stop bit falls back on working position, gear Z2 can not transmit reverse power, and speed changer is in art skating state.Only (tooth is kept off one
Wheel Z1) gearshift is into after surmounting locking position, just by gear Z1 transmission reverse powers.
The above citing is only to the present invention's for example, not constituting the limitation to protection scope of the present invention, all
Be with the present invention it is same or analogous design all belong to the scope of protection of the present invention within.
