The utility model is further described with reference to the accompanying drawings and examples：
The anti-off-gear high speed synchroniser of this automobile as shown in Figure 1, including synchronizer gear sleeve 1 and synchromesh gear hub 7, it is synchronous
The inner ring of device tooth set 1 is provided with axially arranged first groove 101 and the first self-locking hole 102 of more than two, in the present embodiment, the
One groove 101 shares three, is set in 120o；Spline housing 2, spline housing 2 are provided between synchronizer gear sleeve 1 and synchromesh gear hub 7
Inner ring be provided with ring gear and be laid with the second axial groove 203, the outer ring of spline housing 2 is provided with and the first groove 101
First boss 201 corresponding to putting, spline housing 2, can relative synchronization device tooth by the cooperation of the groove 101 of first boss 201 and first
The axial movement of set 1；The outer ring of spline housing 2 is additionally provided with second self-locking hole 202 corresponding with the position of the first self-locking hole 102, and second certainly
Lockhole 702 is located in the second groove 203, and the first self-locking hole 101 is equal with the diameter of the second self-locking hole 202；Synchronizer gear sleeve 1 is to the left
When being moved to certain position, the first self-locking hole 101 overlaps with the position of the second self-locking hole 202；First self-locking hole 102 and the second self-locking
The first self-locking steel ball 3 is provided with hole 202, wherein the first self-locking hole 101 is hemispheric blind hole, the radius of hemispherical blind hole and the
The radius of one self-locking hole 3 is equal；Second self-locking hole 202 is through hole, and the diameter of through hole is slightly larger than the diameter of the first self-locking steel ball 3；
The outer ring of synchromesh gear hub 7 is provided with external tooth corresponding with the ring gear of spline housing 2 and is evenly equipped with the 3rd groove of more than two
703, in the present embodiment, the 3rd groove 703 is three, is set in 120o；The movable slider 6 of radial direction is provided with 3rd groove 703,
Movable slider 6 has sliding block spring；The outer ring of synchromesh gear hub 7 be additionally provided with it is the second of the position correspondence of the second groove 203 convex
Platform 701, second boss 701 are provided with the 3rd self-locking hole 702, the second self-locking steel ball 4 and self-locking spring are provided with the 3rd self-locking hole 702
5, the 3rd self-locking hole 702 is located at the centre position of the outer ring of synchromesh gear hub 7 and is blind hole, and the diameter of the blind hole is slightly larger than second certainly
Lock the diameter of steel ball 4；The diameter of first self-locking hole 102, the second self-locking hole 202 and the 3rd self-locking hole 702 is equal, and in appropriate position
Put the axis coinciding to form three holes；The both sides of synchronizer gear sleeve 1 are provided with rib 103.
Utility model works principle is as follows：This patent is that the shift process of automobile is divided into synchronizer combination and synchronizer
Two processes of locking, wherein entering a grade process：When automobile is in low-grade location, high speed synchroniser is located at neutral gear position as shown in Figure 2, this
When synchronizer gear sleeve 1, spline housing 2 and synchromesh gear hub 7 be substantially flush, the first self-locking steel ball 3 is located at the first self-locking hole 102 and
Between two self-locking holes 202, synchronizer gear sleeve 1 and spline housing 2 are connected as one by the first self-locking steel ball 3, so synchronizer tooth
Set 1 and spline housing 2 relative can not slide；The compression of self-locking spring 5 is placed in the 3rd self-locking hole 702 by the second self-locking steel ball 4, and is pushed up
In the inner side of spline housing 2；When automobile is linked into 5 grades, gearshift fork（It is not drawn into）Synchronizer gear sleeve 1 is driven to slide to the left, certainly
In the presence of locking steel ball 3, synchronizer gear sleeve 1 drives self-locking steel ball 3 and synchronizer gear sleeve 1 to slide axially, when the first self-locking steel ball 3
When sliding into the second self-locking 4 top of steel ball, the spline of spline housing 2 is combined in place with high gear conjunction gear, and speed changer completes five
Keep off shift process；Gearshift fork continues to move in the presence of shift handle, effect of the synchronizer gear sleeve 1 in gearshift fork
Under also continue to be moved to the left, due to spline housing 2 with five gear conjunction gears has been combined in place, it is impossible to axially continue to move to, first oneself
Lock steel ball 3 and depart from the first self-locking hole 102, be pressed completely into the second self-locking hole 202 and part is pressed into the 3rd self-locking hole 702, the
Two self-locking steel balls 4 are then crushed on the lower section of the first self-locking steel ball 3, until gearshift fork is axially moved to fixed gearshift stroke
Afterwards, as shown in figure 4, because the first self-locking steel ball 3 is between spline housing 2 and synchromesh gear hub 7, therefore, by spline housing 2 and together
It is locked to walk device tooth hub 7, completes synchronizer locking process；Because in vehicle traveling process, the spline inside spline housing 2 plays biography
The main function of torque delivery, easy stress and it is out of supply, and at this moment under the lock condition of synchronizer, though spline housing 2 by compared with
Big axial force will not also move axially and cause the generation of failure out of supply.
Move back a grade process：Gearshift fork drives synchronizer gear sleeve 1 axially to the right, when the of the inner side of synchronizer gear sleeve 1
When one self-locking hole 102 is moved to the second 202 surface of self-locking hole of spline housing 2, the first self-locking steel ball 3 and the second self-locking steel ball 4
Upspring and headed into the first self-locking hole 102 on synchronizer gear sleeve 1 by self-locking spring 5, as shown in figure 3, now spline housing 2 and synchronization
Device tooth hub 7 unlocks；Gearshift fork continues to drive synchronizer gear sleeve 1 axially to the right, in the rib of synchronizer gear sleeve 1
Under 103 promotion, spline housing 2 moves right until the spline in spline housing 2 and the conjunction gear of high gear are kept completely separate, and completes
Move back a grade process.
