The male cone (strobilus masculinus) of conjunction；
The endoporus of synchromesh gear hub 6 and it is cylindrical be equipped with spline tooth, it is cylindrical be provided with three circumferences it is uniform be used for cunning is installed
The groove of block；
Synchromesh gear hub 6 is in the middle part of synchronizer assembly, and three synchronizer keys 2 are loaded on three on synchromesh gear hub 6
In circumferential uniform slide block slot, the external spline teeth of inner spline gear and synchromesh gear hub 6 on synchronizer sliding sleeve 1, which coordinates, to be installed, and two
Individual C-shaped wire spring is installed on the both sides of synchromesh gear hub 6, between the crotch in the both sides of synchronizer key 2, in equilbrium position,
Synchronizer sliding sleeve 1 and synchronizer key 2 are in synchronizer center, and the positioning convex in synchronizer key 2 is in synchronizer
In the neutral locating slot of the internal spline of sliding sleeve 1, the inner conical surface of synchronization device cone ring 4 and the male cone (strobilus masculinus) of synchronizer combination gear ring 5 coordinate peace
Dress, occupy the both sides of synchromesh gear hub 6.
In use, it is projecting when completion includes from neutral：Neutral position state, presynchronization lockup state, synchronous phase and
Put into gear and complete several stages.
As shown in Fig. 2 all parts are all in equilbrium position state during neutral, now synchronizer sliding sleeve 1 and synchronizer are slided
Block 2 is in synchronizer center, and it is wide that the middle part positioning convex of synchronizer key 2 is in the internal spline conjunction gear 1/2 of synchronizer sliding sleeve 1
In neutral locating slot at degree.Two C synchronizer shapes springs 3 are respectively at the both sides of synchromesh gear hub 6, in preloading condition.Together
Step device conical ring 4 and synchronizer combination gear ring 5 are in free state.
Presynchronization lockup state, such as, exemplified by putting into gear to the left, as shown in Figure 10, synchronizer sliding sleeve 1 is hung in speed changer
Keep off under the promotion of shift fork, leave centre position and moved to the direction of synchronizer combination gear ring 5 on the left of synchronizer.At this moment, synchronizer
The neutral locating slot right flank of sliding sleeve 1 is bonded with the right flank of the positioning convex of synchronizer key 2, promotes synchronizer key 2 and a left side
The synchronization device cone ring 4 of side moves to the left together, makes the inner conical surface of synchronization device cone ring 4 and the synchronizer conjunction gear in left side in left side
The male cone (strobilus masculinus) fitting of circle 5, two friction surfaces of friction element are in contact.Due to synchronization device cone ring 4 and synchronizer combination gear ring 5 with
Different angular speed operatings, moment of friction caused by speed discrepancy caused by moment of inertia make synchronization device cone ring 4 relative to synchronizer
Sliding sleeve 1 rotates an angle, and the increment locking inclined-plane of synchronizer sliding sleeve 1 contacts with the increment locking surface on synchronization device cone ring 4, enters
Lock position, prevent synchronizer sliding sleeve 1 from continuing movement of putting into gear to the left, put into gear before preventing synchronously.
Synchronous phase, in the case where continuing to apply responsive to axial force to the left to synchronizer sliding sleeve 1, on the conical surface of synchronization device cone ring 4
Pressure continue to increase, make the angular speed of two cones of friction of the synchronization device cone ring 4 with synchronizer combination gear ring 5 during sliding wear
Move closer to, after moment of friction overcomes the moment of inertia of engaged part, speed discrepancy and frictional force between two friction surfaces
Square disappears, and at this moment synchronizer combination gear ring 5 is identical with the rotating speed of synchronizer sliding sleeve 1, completes synchronizing process.
After synchronous phase terminates, the speed discrepancy vanishing between synchronization device cone ring 4 and synchronizer combination gear ring 5 is synchronous to turn
Square and friction torque are disappeared, and the axial force on synchronizer sliding sleeve 1 is still acted on synchronization device cone ring 4, and locking surface normal pressure is cut
Synchronization device cone ring 4 is reversed an angle to lock-off torque caused by component and return just, two locking surfaces disengage, and complete de-
Lock.
Put into gear the completion stage, as shown in figure 11, after synchronization device cone ring 4 sets right, synchronizer sliding sleeve 1 pushes away in shift fork of putting into gear
Power effect is lower to continue the direction of synchronizer combination gear ring 5 slip to the left, and C-shaped synchronizer spring 3 is compressed and straight by synchronizer key 2
Footpath reduces, and the neutral locating slot of synchronizer sliding sleeve 1 crosses the positioning convex in synchronizer key 2, the internal spline of synchronizer sliding sleeve 1 and
The external splines engagement of synchronizer combination gear ring 5, is linked into targeted gear synchronizer combination gear ring 5, completes to put into gear.
When plucking gear, shift fork of putting into gear drives synchronizer sliding sleeve 1 to move to the right, the internal spline of synchronizer sliding sleeve 1 and synchronizer knot
Close the external splines of gear ring 5 to be disengaged from, now under the return tension force effect of C-shaped synchronizer spring 3, determine in synchronizer key 2
Position projection is pressed into the neutral locating slot of synchronizer sliding sleeve 1, and all parts return to equilbrium position, and gear is plucked in completion.
So far, the once reciprocating motion of gearshift terminates.Synchronizer to the right put into gear the course of work and left side phase by side direction
Together.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
