Description
Technical field
The present invention relates to a kind of attenuated tooth synchronizer sliding sleeve gear.
Background technique
The internal surface of the synchronous sliding sleeve of current automobile synchronizer is provided with internal spline and is provided with because profile of tooth is identical between external splines with the outer surface of synchronous gear seat, and the coaxality therefore between them is poor, and centering precision is poor.
Summary of the invention
The invention provides a kind of attenuated tooth synchronizer sliding sleeve gear, it not only can improve the root diameter Spielpassung of tip diameter and synchronous gear seat, the centering precision of both raisings spline, and the coaxality adding the two.
Present invention employs following technological scheme: a kind of attenuated tooth synchronizer sliding sleeve gear, it comprises synchronous sliding sleeve and synchronous gear seat, synchronous sliding sleeve is connected with synchronous gear seat by spline fitted, the internal surface of described synchronous sliding sleeve is provided with internal spline, the outer surface of described synchronous gear seat is provided with external splines, the internal spline of described synchronous sliding sleeve comprises some inner spline gears I and some inner spline gears II, some inner spline gear II uniform intervals distribute between some inner spline gears I, the external spline teeth of external splines is corresponding with inner spline gear I, the transverse tooth thickness of inner spline gear II is thinner than inner spline gear I, the tooth depth of inner spline gear II is higher than inner spline gear I, during gear shift, synchronous sliding sleeve moves left and right vertically on synchronous gear seat, the tip diameter of inner spline gear II is corresponding with the external spline teeth root diameter gap of the external splines of synchronous gear seat.
Also support assembly is provided with between described synchronous sliding sleeve and synchronous gear seat, support assembly comprises supporting base, fluid column and spring, and supporting base is positioned at the mounting groove that synchronous gear seat is provided with, and is positioned at mounting groove in the bottom of supporting base, spring housing is at supporting base, and supporting base withstands synchronous sliding sleeve by fluid column.
The present invention has following beneficial effect: after have employed above technological scheme, synchronous sliding sleeve of the present invention is connected with synchronous gear seat by spline fitted, the internal surface of described synchronous sliding sleeve is provided with internal spline, the outer surface of described synchronous gear seat is provided with external splines, the internal spline of described synchronous sliding sleeve comprises some inner spline gears I and some inner spline gears II, some inner spline gear II uniform intervals distribute between some inner spline gears I, the transverse tooth thickness of inner spline gear II is thinner than inner spline gear I, the tooth depth of inner spline gear II is higher than inner spline gear I, during gear shift, synchronous sliding sleeve moves left and right vertically on synchronous gear seat, the tip diameter of inner spline gear II is corresponding with the external spline teeth root diameter gap of the external splines of synchronous gear seat, some inner spline gears II of such synchronous sliding sleeve are more thinning than the external spline teeth of the external splines of synchronous gear seat, increase tooth depth simultaneously, form fine-high-gear structure.The tip diameter of thin and tall tooth and the root diameter Spielpassung of synchronous gear seat, improve outer surface that the internal surface of synchronous sliding sleeve is provided with internal spline and synchronous gear seat and be provided with centering precision between external splines, add the coaxality of internal spline and external splines, when not improving the spline fitted precision of internal spline and external splines, improve the centering precision of internal spline and external splines, improve internal spline and external splines from slip.
