Also it is engaged with the carrier gear Z6, at this point, just realizing reverse gear.
In addition, as the anti-rear slip device in this implementation, the tail end of the power output of the output shaft 1 is arranged on, is leaned on
At nearly case of transmission, the outer ring 202 of the one-way rotation mechanism 2 is by bolt 4 by its axial lock in housing 3(The shell
Body can be the housing of built-in secondary gear, with the housing of engine entirety or can be individually for anti-rear slip device setting
Housing)Endoporus on, may be provided with multiple latched positions, and be distributed on the periphery of outer ring 202, outer ring and shell ensured with this
The bonding strength of body 3.
The hole of output shaft 1 position is installed by being set on housing 3, by the center of outer ring 202 and the center pair of hole position
Then standard is locked it on the endoporus of housing 3 using bolt 4, the same of outer ring 202 and output shaft 1 has been ensured by housing 3
Heart degree, it is low to 202 processing request of outer ring, and concentricity is improved.
Wherein, the inner ring 201 is placed on the output shaft 1, that is to say, that between the inner ring 201 and output shaft 1
With gap, the output shaft 1 can not directly act on the inner ring of one-way rotation mechanism 2, need to can be real by lazy-tongs
The power transmission of existing output shaft 1 and one-way rotation mechanism 2, concrete structure have following several ways:
Mode one:Synchronous gear 5 is provided on the output shaft 1, the synchronous gear 5 is external tooth, with the output shaft 1 one
Body sets or is keyed with the output shaft 1.In the present embodiment, the synchronous gear 5 is connected with the output shaft 1 by spline
It connects.Be provided with conjunction gear 6 on the inner ring 201, the conjunction gear 6 is also external tooth, and the conjunction gear 6 be with it is described synchronous
The consistent external tooth of 5 gear parameter of tooth.And the lazy-tongs include synchronous ring 9, the synchronous ring 9 has can be with the synchronous gear
The internal gear of 5 engaged transmissions, is provided with annular groove on synchronous 9 outer wall of ring, shift fork 10 is provided in the annular groove.Pass through
Shift fork 10, which can stir the synchronous ring 9, to be made it while is engaged with the synchronous gear 5 and conjunction gear 6, at this point, the output shaft 1 is logical
It crosses synchronous gear 5 to be combined with the inner ring 201, the realization of inner ring 201 is rotated synchronously with the output shaft 1;By shift fork 10 also
The synchronous ring 9, which can be stirred, makes it only be engaged with the synchronous gear 5, at this point, the inner ring 201 is only placed in the output shaft
On 1, output shaft 1 can not drive the inner ring 201 to rotate.
Mode two:The inner ring 201 includes single direction rotation connector 201a and combined cover 201b, the combined cover 201b is empty
It is placed on outside the output shaft 1, the single direction rotation connector 201a is set on outside the combined cover 201b and can be with the combined cover
201b is rotated synchronously, and is formed a fixed connection;And the single direction rotation connector 201a can only realize list relative to the outer ring 202
It is to rotation, i.e., consistent with the forward direction of the output shaft 1.
And the conjunction gear 6 is arranged on the combined cover 201b, the conjunction gear 6 on the combined cover 201b is can be with institute
The internal gear of 5 engaged transmission of synchronous gear is stated, annular groove is provided on the outer wall of the conjunction gear 6, is provided in the annular groove
Shift fork 10.Can stir the combined cover 201b by shift fork 10 makes conjunction gear 6 thereon engage or detach with the synchronous gear 5,
When the conjunction gear 6 is engaged with the synchronous gear 5, the output shaft 1 drives the combined cover 201b and single direction rotation to engage
Device 201a is rotated, that is, the inner ring 201 is driven to rotate;When the shelves conjunction gear 6 is detached with the synchronous gear 5, the output shaft 1
Power is in mutually from state with the combined cover 201b, and the output shaft 1 can not drive the inner ring 201 to rotate.
Mode three:In this mode, the conjunction gear 6 is also provided on the combined cover 201b, only the conjunction gear 6
For the external tooth consistent with 5 gear parameter of synchronous gear, there is synchronous ring 9 in 5 external toothing of synchronous gear, the synchronous ring 9 is logical
Crossing stirring for shift fork 10 can realize while be engaged with the synchronous gear 5 and conjunction gear 6, can also realize only with the synchronous gear 5
Engagement.When synchronous ring 9 engages simultaneously with synchronous gear 5 and conjunction gear 6, output shaft 1 drives the inner ring 201 to rotate, and works as synchronization
When ring 9 is only engaged with synchronous gear 5, output shaft 1 can not drive inner ring 201 to rotate.
When vehicle is in forward traveling or dead ship condition, the inner ring 201 and the output shaft 1 are made by synchronizer
In bonding state.At this point, since the inner ring 201 can only realize single direction rotation, i.e., rotated forward with output shaft 1(Preceding line direction)One
The rotation of cause is slipped so can effectively avoid vehicle in climbing, abrupt slope starting, abrupt slope parking there is a situation where after.
When vehicle needs backward, discrete state is in by the synchronizer inner ring 201 and the output shaft 1
(I.e. output shaft 1 can not drive the inner ring 201 to rotate), at this point, output shaft 1 can realize reversion, realize vehicle backing.
Wherein, the single direction rotation connector 201a mentioned in the present embodiment can be can only after existing and outer ring 202 coordinates
Realize the cam wedge mechanism of single direction rotation, cam+roller mechanism, cam+ball bearing mechanism, cam+ball spring mechanism etc..
In this implementation, the single direction rotation connector 201a is using cam wedge mechanism.
As another embodiment in the present embodiment, also set up between the combined cover 201b and the output shaft 1
There is oiliness bearing 8 so that the relative motion between combined cover 201b and output shaft 1 is more smooth.
As another embodiment in the present embodiment, the shift fork 10 is connect with reverse speed shift rod 11, normally travel
Or during neutral gear, synchronous ring 9 engages simultaneously with the synchronous gear 5 and conjunction gear 6.When needing reversing, driven while hanging reverse gear
The reverse speed shift rod 11, which slides, drives the shift fork 10 on synchronous ring 10 to slide so that and synchronous ring 9 is only combined with synchronous gear 5, this
When, it can be achieved that backward.Synchronism switching is achieved the effect that.
Outer ring 202 in the present embodiment realize and output shaft is concentric installs that the inner ring 201 is located at outer ring by housing 3
