Abstract
An anti-off-gear length spline structure of putting into gear for automobile, the reverse gear of its main empty set on axle, is equipped with toothholder by inside and outside spline housing on the axle of this reverse gear one avris, on this toothholder, is equipped with sliding sleeve by inside and outside spline housing; Consistent and the flank profil middle, external splines both sides of spline length on toothholder is provided with the slight convex chain-wales that can stop that sliding sleeve moves to both sides off-gear; Spline on described sliding sleeve and reverse gear is for moving left and right length tooth spline easily; Described sliding sleeve internal spline is in the time moving into place, power is by the transmission of axle → toothholder → sliding sleeve → reverse gear, in the time of transferring power, sliding sleeve inner spline gear one side will tightly be fitted with toothholder external spline teeth one side, simultaneously again because there is slight convex chain-wales flank profil middle, toothholder external splines both sides, thereby will well stop that sliding sleeve is moved to the left there is off-gear phenomenon; It is more simple compact that it has structure, and Security and reliability are higher, puts into gear and the feature such as be more prone to.
Description
Technical field
The utility model relates to a kind of anti-off-gear length spline structure of putting into gear for automobile, belong to the gearshift device of gear train assembly.
Background technique
Put into gear in mechanism reversing gear of existing most of automobile gearbox, for saving cost, synchronizer gear shifting structure is not generally installed, this just makes to hang and exist feel jerky when reversing gear at vehicle, is not easy into gear, and the problems such as " beating tooth " phenomenon even occur.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of structure more simple compact, and Security and reliability are higher, puts into gear more smoothly for the engaging gear structure that reverses gear of automobile gearbox.
The utility model completes by following technical solution, and the reverse gear of its main empty set on axle, is equipped with toothholder by inside and outside spline housing on the axle of this reverse gear one avris, on this toothholder, is equipped with sliding sleeve by inside and outside spline housing; Consistent and the flank profil middle, external splines both sides of spline length on toothholder is provided with the slight convex chain-wales that can stop that sliding sleeve moves to both sides off-gear; Spline on described sliding sleeve and reverse gear is for moving left and right length tooth spline easily.
Described sliding sleeve internal spline is in the time moving into place, power is by the transmission of axle → toothholder → sliding sleeve → reverse gear, in the time of transferring power, sliding sleeve inner spline gear one side will tightly be fitted with toothholder external spline teeth one side, simultaneously again because there is slight convex chain-wales flank profil middle, toothholder external splines both sides, thereby will well stop that sliding sleeve is moved to the left there is off-gear phenomenon.
When hanging while reversing gear, stir sliding sleeve to the right by stirring shift fork, sliding sleeve moves right and enters reverse gear spline, the sliding sleeve internal spline making due to the existence of length spline will become and be more prone in the time entering reverse gear spline, when the internal spline of sliding sleeve moves into place, power transmits by sliding sleeve, sliding sleeve inner spline gear one side will tightly be fitted with toothholder external spline teeth one side, simultaneously again because there is slight convex chain-wales flank profil middle, toothholder external splines both sides, thereby will well stop that sliding sleeve is moved to the left there is off-gear phenomenon.
In the time wanting off-gear, stir sliding sleeve left by stirring shift fork, sliding sleeve is shifted out to spline engagement district.
The utlity model has structure more simple compact, Security and reliability are higher, the feature such as put into gear more smooth and easy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the perspective view of sliding sleeve described in the utility model.
Fig. 3 is the perspective view of toothholder described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2,3, the utility model mainly contains the reverse gear 1 of an empty set on axle, on the axle 2 of these reverse gear 1 one avris, be equipped with toothholder 3 by inside and outside spline housing, on this toothholder 3, be equipped with sliding sleeve 4 by interior external splines 5; Consistent and the flank profil middle, external splines both sides of spline length on toothholder 3 is provided with the slight convex chain-wales 6 that can stop that sliding sleeve moves to both sides off-gear; Spline on described sliding sleeve 4 and reverse gear 1 is for moving left and right length tooth spline 7 easily.
Shown in figure, when hanging while reversing gear, stir sliding sleeve to the right by stirring shift fork, sliding sleeve moves right and enters reverse gear spline, the sliding sleeve internal spline making due to the existence of length spline will become and be more prone in the time entering reverse gear spline, when the internal spline of sliding sleeve moves into place, power is by the transmission of axle → toothholder → sliding sleeve → reverse gear, in the time of transferring power, sliding sleeve inner spline gear one side will tightly be fitted with toothholder external spline teeth one side, simultaneously again because there is slight convex chain-wales flank profil middle, toothholder external splines both sides, will well stop that thereby sliding sleeve is moved to the left generation off-gear phenomenon.
In the time wanting off-gear, first interrupt power, sliding sleeve inner spline gear one side and the no longer tightly laminating of toothholder external spline teeth one side, stir sliding sleeve left by stirring shift fork, and sliding sleeve is shifted out to spline engagement district.
Claims (2)
1. an anti-off-gear length spline structure of putting into gear for automobile, the reverse gear of its main empty set on axle, is characterized in that being equipped with toothholder by inside and outside spline housing on the axle of this reverse gear one avris, on this toothholder, is equipped with sliding sleeve by inside and outside spline housing; Consistent and the flank profil middle, external splines both sides of spline length on toothholder is provided with the slight convex chain-wales that can stop that sliding sleeve moves to both sides off-gear; Spline on described sliding sleeve and reverse gear is for moving left and right length tooth spline easily.
2. anti-off-gear length spline structure of putting into gear for automobile according to claim 1, it is characterized in that described sliding sleeve internal spline is in the time moving into place, power is by the transmission of axle → toothholder → sliding sleeve → reverse gear, in the time of transferring power, sliding sleeve inner spline gear one side will tightly be fitted with toothholder external spline teeth one side, simultaneously again because there is slight convex chain-wales flank profil middle, toothholder external splines both sides, thereby will well stop that sliding sleeve is moved to the left there is off-gear phenomenon.
