Principle of the present invention:
The present invention is on the basis of lock ring type synchronizer, change lock ring type synchronizer sliding sleeve, synchronizing ring, in conjunction with the spline engagement tooth of gear ring, the mesh tooth face of spline both sides is designed to dissymmetrical structure, and situation about using in speed changer according to synchronizer, consider that working principle suitably increases degree of asymmetry, not affecting on the basis of working life and reliability, can significantly improve locking reliability, guarantee the synchronous torsion pass function that synchronizer has.The present invention is also applicable to not having in conjunction with gear ring 4 with the change gear with spline tooth of sliding sleeve 6 engagements, now the spline tooth of change gear can be made with in conjunction with the identical asymmetric spline engaging tooth of gear ring 4.
At engaging tooth and teeth link position, increase knuckle or chamfering in addition, this is gear shifting force progressively excessively provides architecture basics, can guarantee the steady and smooth of gearshift.
1) size of synchronizer engaging tooth degree of asymmetry determines it is a difficult point, when Parameter of spline is determined, the facewidth of spline is also just determined, guaranteeing under the flank of tooth angle of lock that locking requires, degree of asymmetry more idle stroke is shorter, after synchronous, the secondary ring of gear shift engagement impacts also by little, but excessive degree of asymmetry will cause the excessive easy generation quenching infiltration of heat treatment deformation, make the easy brittle failure of whole spline tooth.
2) processing of asymmetric tooth is processed with higher difficulty than symmetric teeth, especially when engaging tooth and teeth position increase knuckle or chamfering, will make difficulty of processing further promote, cost is also relatively high, wherein the effect of fillet is more obvious than chamfering, but difficulty of processing is higher than chamfering.
Working procedure of the present invention:
Referring to Fig. 1, suppose to apply the present invention in one grade of certain model speed changer and two file locations, front from Fig. 1, suppose that one grade of gear is positioned at the left side that the right side of Fig. 1, intermediate gear are positioned at Fig. 1, the input end of speed changer is in left side, output terminal is on right side, and so from output terminal toward input end, transmission output shaft is rotated counterclockwise.
The speed changer of take is below put in the first speed the working principle of this invention is described as example by second gear, when two file locations, speed changer two axle rotating speeds are higher, one grade of gear rotational speed is lower, when putting in the first speed, the sliding sleeve 6 band movable sliders 7 of synchronizer move right together with pin 8, during near one grade of side synchronizing ring, under ring moment loading, will rotate to an angle along axis, then make the sliding sleeve long flank of tooth 6b of engagement of sliding sleeve 6 and the long flank of tooth 1b of synchronizing ring engagement of synchronizing ring of synchronizer cut gradually and laminating completely, now enter synchronous lockup state, the friction ring of synchronizer is adjacent to mutually, under the effect of friction torque, one grade of gear rotational speed raises, speed changer two axle rotating speeds reduce, when the two speed discrepancy equates substantially, friction torque disappears, the existence of ring moment makes synchronizing ring reversion several angle, the long flank of tooth 6b of the now sliding sleeve of sliding sleeve engagement crosses synchronizing ring spline straight-tooth part, meshing short flank of tooth 4a with combination gear ring in conjunction with gear ring produces slight impact and contacts, slip over spline engagement flank of tooth knuckle 4d and refer to spline teeth 4c, the teeth and engagement in conjunction with the teeth 4c of gear ring 4 of the sliding sleeve 6 of synchronizer have finally been realized, now power is via intermediate gear, in conjunction with gear ring 4, sliding sleeve 6, tooth hub 5, two axle transmission, be that speed changer is hung smoothly into one grade.
When synchronizer is hung second gear by one grade, when a file location, speed changer two axle rotating speeds are lower, intermediate gear rotating speed is higher, sliding sleeve is moved to the left and makes friction ring generation friction torque that intermediate gear rotating speed is reduced, two axle rotating speeds raise, and both reach equal, complete synchronous, other process is similar to the above, and sliding sleeve, synchronizing ring spline engagement are used is respectively the sliding sleeve long flank of tooth 6b of engagement and the long flank of tooth 1b of synchronizing ring engagement, in conjunction with the use of gear ring spline engagement, be to mesh short flank of tooth 4a in conjunction with gear ring.
As shown in Figure 5, one grade of the present invention break away the short flank of tooth 6a of cover engagement upward, the long flank of tooth 6b of sliding sleeve engagement down; Second gear break away the short flank of tooth 6a of cover engagement down, the long flank of tooth 6b of sliding sleeve engagement upward; For a set of synchronizer, combination gear ring and the synchronizing ring of both sides can be general like this, can not occur wrongly installedly, do not increase new part.But sliding sleeve need to be distinguished the gear of use, should on sliding sleeve, identify the mark of distinguishing gear, otherwise wrongly installed and design idea can occur runs counter to, certain lock ring type synchronizer assembly for example, the low-grade side of dress should be in speed changer a file location, the high-grade side of dress should be in speed changer two file locations, can not pack a side of low grade into two file locations, pack a side of top grade into a file location.So should note preventing the anti-loaded usage requirement that affects when assembling synchronizer assembly and two axle assemblies.
Sliding sleeve of the present invention, synchronizing ring, can be identical in conjunction with the spline engagement tooth degree of asymmetry of gear ring, can be not identical yet, degree of asymmetry is with respect to the ratio of the long face width of tooth in the both sides that form after former symmetrical Surface of action centerline offset certain distance and the short face width of tooth.Degree of asymmetry is larger, and synchronous rear secondary pulse improves more obvious, and smoothness and the mildness of shifting of transmission are more obvious.Distance with respect to former symmetrical Surface of action centerline offset certain distance is m, and as shown in figure 10, generally the value of m is at 0.5～2mm, and relevant with the transverse tooth thickness of spline engagement tooth, transverse tooth thickness is larger, and corresponding m value can suitably be got large value.Suppose that spline engagement tooth transverse tooth thickness is s, degree of asymmetry ξ=(s/2+m)/(s/2-m) just can determine.
The angle k of two lateral tooth flanks of asymmetric spline engaging tooth determines, generally both sides angle equates, be k=2p, but also can be unequal, the angle requirement of principal security angle of lock k-p when unequal, generally k-p is at 55 °～65 °, and relevant with the synchronous Capacity design requirement of synchronizer, k value is generally at 110 °～130 °.
As shown in figure 11, another structure of the present invention is made bilateral symmetry structure by sliding sleeve, this structure does not have special matching requirements in speed changer to sliding sleeve, but the synchronizing ring of both sides must be two parts, the long flank of tooth of asymmetric engaging tooth is just contrary, and when assembling, guaranteeing can not be wrongly installed; The combination gear ring of both sides must be also two parts, and the long flank of tooth of asymmetric engaging tooth is just contrary, and in when assembling, guaranteeing can not be wrongly installed, therefore that cost is compared dissymmetrical structure is higher.
Asymmetric engaging tooth is more difficult than the processing of symmetrical engaging tooth, especially processing in conjunction with gear ring mesh short flank of tooth 4a and spline teeth 4c, during in conjunction with the spline engagement tooth knuckle 4d of the gear ring long flank of tooth 4b of engagement and spline teeth 4c joint, so the higher manufacture cost of structure needs.Spline teeth 4c in conjunction with gear ring can be fillet or chamfering, and mesh short flank of tooth 4a and spline teeth 4c, can be different in conjunction with fillet and the chamfering of the gear ring long flank of tooth 4b of engagement and spline teeth 4c.Wherein the effect of fillet is more obvious than chamfering, but difficulty of processing is higher than chamfering.If difficult at manufacture view, can remove spline teeth 4c, but should guarantee to mesh short flank of tooth 4a and spline teeth 4c, in conjunction with the transition position of the gear ring long flank of tooth 4b of engagement and spline teeth 4c, do not have cusp to give prominence to and burr.
Above content is only explanation technological thought of the present invention; can not limit protection scope of the present invention with this; every technological thought proposing according to the present invention, any change of doing on technological scheme basis, within all falling into the protection domain of the claims in the present invention book.
