Description
Technical field
The utility model relates to a kind of anti-off-gear toothholder synchronizer.
Background technique
Automobile synchronizer is the critical component of mechanical type gear-driving speed-variable device, uses synchronizer gearshift light and flexible, and during gearshift, gear, axle are not hit, and extend the speed changer life-span, reduce labor intensity, improve the power performance and the economy performance of automobile.Synchronizer is born the effect of gearshift, transmitting torque, is crucial, easily damaged parts in gearbox.After the long-term use of current automobile synchronizer, easily there is falling gear phenomenon.
Summary of the invention
The utility model provides a kind of anti-off-gear toothholder synchronizer, and it walks in use device and is difficult for falling gear, has increased the reliability of putting into gear.
The utility model has adopted following technological scheme: a kind of anti-off-gear toothholder synchronizer, it comprises synchronous sliding sleeve and synchronous gear seat, the inwall of described synchronous sliding sleeve is provided with internal spline, on described synchronous gear seat, outer surface is provided with external splines, synchronous sliding sleeve is coupled to each other by internal spline and coordinating of external splines with synchronous gear seat, the external splines middle part of described synchronous gear seat is thick tooth, two ends are thin tooth, under neutral situation, the middle part of synchronous gear seat is that thick tooth is meshed with the internal tooth of synchronous sliding sleeve internal spline, during gearshift, synchronous sliding sleeve moves left and right vertically on synchronous gear seat, the internal tooth of synchronous sliding sleeve internal spline is meshed with the thin tooth of one end of synchronous gear seat external splines.
The marginal distribution of described synchronous gear seat has some grooves, between each groove and synchronous sliding sleeve, is provided with roller, and roller is supported by supporting base, and on supporting base, cover has spring, and spring is positioned at groove.The external splines external diameter of described synchronous gear seat matches with the internal spline internal diameter of synchronous sliding sleeve.
The utlity model has following beneficial effect: adopted after above technological scheme, the inwall of the utility model synchronous sliding sleeve is provided with internal spline, on synchronous gear seat, outer surface is provided with external splines, the external splines connection that matches with synchronous sliding sleeve internal spline, the external splines external diameter of synchronous gear seat matches with the internal spline internal diameter of synchronous sliding sleeve, can guarantee that like this synchronous gear seat and synchronous sliding sleeve are coaxial, synchronous gear seat and synchronous sliding sleeve driving torque.Synchronous sliding sleeve internal spline moves along synchronous gear seat external splines, the external splines middle part of synchronous gear seat is thick tooth, two ends are thin tooth, after synchronizer is put into gear, because of the effect of unidirectional torque, during gearshift, synchronous sliding sleeve moves left and right vertically on synchronous gear seat, and the internal tooth of synchronous sliding sleeve internal spline is meshed with the thin tooth of one end of synchronous gear seat external splines, can avoid like this synchronizer to fall gear, and simple in structure.The utility model is under neutral situation, and the middle part of synchronous gear seat is that thick tooth is meshed with the internal tooth of synchronous sliding sleeve internal spline, has guaranteed so the normal back lash of spline of synchronous gear seat and synchronous sliding sleeve, has avoided neutral noise.
