Beneficial effect: the utility model discloses create prevent plucking difficult synchronous ware of fender sheathes in at the tooth and has set up six direction teeth, and restriction synchronizer ring's circumferencial direction deflects, can avoid synchronizer ring to break away from back and the bottom plane contact of tooth cover back taper, and it is smooth to make the tooth cover pluck the fender.
Description
Technical field
This utility model is created and is belonged to automobile manufacturing field, especially relates to a kind of anti-plucking and keeps off difficulty lock unit.
Background technology
Automobile synchronizer is a kind of plant equipment realizing automobile balance gearshift, in conventional gear box, engage smoothly to be able to make gear reach consistent rotating speed, realize smooth-going, shock-free gear shift operation, many employing lock units realize gear shift operation, as shown in figure, although this structure is widely used, but it there is also certain deficiency: under normal circumstances, tooth set moves axially a segment distance, it is achieved put into gear, and now the synchronous ring conical surface unclamps with combining the gear ring conical surface, no longer transmitting moment of torsion, synchronous ring relies on inertia to overlap spline back taper contact with platform with tooth；When plucking gear, synchronous ring produces resistance to tooth set, stops tooth set to return to neutral, causes and plucks gear difficulty, the problem that even can not pluck gear, brings negative influence.
Utility model content
In view of this, this utility model creation is directed to a kind of anti-plucking and keeps off difficulty lock unit, this lock unit is provided with six on tooth overlaps and guides tooth, the circumferencial direction deflection of limits synchronization ring, synchronous ring can be avoided to contact with tooth cover back taper base plane after departing from, effectively solve automobile in running, pluck the problem that gear difficulty even can not pluck gear.
For reaching above-mentioned purpose, the technical scheme that this utility model is created is achieved in that
A kind of anti-plucking keeps off difficulty lock unit, including coaxially arranged tooth set, tooth hub, synchronous ring and gear, described tooth set socket-connects with tooth hub, synchronous ring is in the side of tooth hub, and socket-connect with tooth set, the cone of described gear edge is positioned at below synchronous ring, the outer of tooth hub is provided with groove in axial direction, the interior edge of tooth set is fixed with slide block, slide block is corresponding with the position of described groove, described tooth set is by small slide block, common internal tooth and guiding internal tooth annularly inwall cross-distribution composition, described synchronous ring is by spacing even tooth, common teeth groove and guiding teeth groove annularly outer wall cross-distribution composition.
Further, described guiding internal tooth has six, and is uniformly distributed in the inner side of tooth set.
Further, described guiding teeth groove has six, and is uniformly distributed in the outer of synchronous ring, engages with guiding internal tooth.
Further, the guiding teeth groove both sides width of described synchronous ring all reduces 0.35mm, and at tooth set internal spline, both sides transverse tooth thickness all reduces 0.35mm.
Relative to prior art, the anti-gear difficulty lock unit of plucking described in this utility model creation has the advantage that
(1) anti-gear difficulty lock unit of plucking described in the utility model is provided with guiding tooth on tooth set, and the circumferencial direction deflection of limits synchronization ring effectively solves automobile and plucks the problem that gear difficulty even can not pluck gear in running.
(2) anti-gear difficulty lock unit guiding tooth of plucking described in the utility model is six, synchronous ring can be avoided to contact with tooth cover back taper base plane after departing from, increase and pluck gear power.
(3) amount that amount with the synchronous ring common teeth groove thinning due to tooth set transverse tooth thickness described in the utility model reduces is consistent, so flank fit clearance is constant, identical with normal between cog cooperation, can effectively solve to pluck gear difficult problem, the most not affect other position functions.

Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in this utility model creation and the feature in embodiment can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail to create.
This utility model is created anti-the plucking of one and is kept off difficulty lock unit, as shown in Figure 2, including coaxially arranged tooth set 1, tooth hub 2, synchronous ring 3 and gear, described tooth set 1 socket-connects with tooth hub 2, synchronous ring 3 is in the side of tooth hub 2, and socket-connect with tooth set 1, described gear is provided with cone 4, the outer of tooth hub 2 is provided with groove in axial direction, the interior edge of tooth set 1 is fixed with slide block 5, slide block 5 is corresponding with the position of described groove, described tooth set 1 is by small slide block, common internal tooth 11 and guiding internal tooth 12 annularly inwall cross-distribution composition, described synchronous ring 3 is by spacing even tooth, common teeth groove 31 and guiding teeth groove 32 annularly outer wall cross-distribution composition.
As shown in Figure 3 and Figure 4, described guiding internal tooth 12 has six, and is uniformly distributed in the inner side of tooth set 1, and tooth overlaps both sides transverse tooth thickness at 1 internal spline and all reduces 0.35mm.
As shown in Figure 5 and Figure 6, described guiding teeth groove 32 has six, and is uniformly distributed in the outer of synchronous ring 3, engages with guiding internal tooth 12, and the common teeth groove 31 both sides width of synchronous ring 3 all reduces 0.35mm.
It is consistent owing to tooth overlaps the amount of the thinning amount of 1 transverse tooth thickness teeth groove 31 common with synchronous ring 3 reduction, so flank fit clearance is constant, identical with normal between cog cooperation.
The foregoing is only the preferred embodiment that this utility model is created; not in order to limit this utility model creation; within all spirit in this utility model creation and principle, any modification, equivalent substitution and improvement etc. made, within should be included in the protection domain that this utility model is created.
