Abstract

The utility model discloses a third and fourth gear synchronizer toothed sleeve with improved reversed taper teeth. An annular gear of the toothed sleeve consists of internal spline teeth, wherein the reversed taper teeth are arranged at the two ends of each internal spline tooth, and an oblique angle of each reversed taper tooth is a. The toothed sleeve is characterized in that a is greater than 3.7 DEG and less than 4.5 DEG; the internal spline teeth comprise three groups of uniformly distributed high teeth and three groups of uniformly distributed low teeth; each group of high teeth comprises two adjacent high teeth; and each group of low teeth comprises three adjacent low teeth. With the adoption of the toothed sleeve, gear engaging is smooth, gear dislocating can be avoided effectively, and the linkage precision is higher.

Description

Have the three fourth gear synchronizer gear sleeves that improve teeth

Technical field

The utility model relates to a kind of improvement invention of three fourth gear synchronizer gear sleeves.

Background technique

Synchronizer gearshift not only have gearshift light, avoid impacting, eliminate noise, extend the advantages such as gear life, and can also make gearshift rapidly, improve power character, the economical and Security of automobile, therefore, the gearshift of Hyundai Motor, particularly car nearly all adopts this device.Synchronizer mainly is comprised of tooth cover, tooth hub, synchronous lock ring etc., and its feature is to rely on rubbing action to realize synchronously.Three fourth gear synchronizer gear sleeves of prior art, the angle of bevel of the teeth that its inner spline gear two ends are provided with is unreasonable, can cause engage a gear to have some setbacks when angle of bevel is excessive, can occur easily out of supply when angle of bevel is too small, so the rational teeth angle of bevel of how to confirm is crucial; In addition, existing three fourth gear synchronizers adopt large footpath and flank centering mode, are subjected to the impact of synchromesh gear hub, tooth cover circularity and spline accumulation runout error, and the interlock precision of synchronizer is not high.

Summary of the invention

In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of engage a gear smooth and easy, can effectively prevent out of supplyly, and the precision that links simultaneously is higher has the three fourth gear synchronizer gear sleeves that improve teeth.

The utility model is implemented by the following technical programs:

Have the three fourth gear synchronizer gear sleeves that improve teeth, its ring gear is comprised of inner spline gear, and the two ends of inner spline gear are provided with teeth, and the oblique angle of teeth is a, it is characterized in that: the angle of a greater than 3.7o less than 4.5o.

After adopting technique scheme, not only make three fourth gear synchronizer gear sleeves very smooth and easy when engage a gear, prevented simultaneously problem out of supply after the engage a gear, improved the interlocking performance.

As optimal technical scheme, described inner spline gear comprises three groups of uniform high teeth and three groups of uniform low teeth, and every group high tooth is adjacent two, and every group low tooth is adjacent three.After adopting above-mentioned design, three fourth gear synchronizer gear sleeves can with the supporting path centering that realizes three fourth gear synchronizers of tooth hub, centering accurately, thereby make the interlock precision better.

Description of drawings

The utility model has following accompanying drawing:

Fig. 1 is structural drawing of the present utility model,

Fig. 2 is the D-D view of Fig. 1,

Fig. 3 is the C-C view of Fig. 2.

Embodiment

As shown in the figure, of the present utility model have three fourth gear synchronizer gear sleeves that improve teeth, and its ring gear is comprised of 27 intragranular spline tooths 1, comprises three groups of uniform high tooth 1a and three groups of uniform low tooth 1c, every group high tooth 1a is adjacent two, totally six of high tooth 1a, every group low tooth 1c is adjacent three, totally nine of low tooth 1c, all the other ten bidentates are orthodont 1b, the two ends of described inner spline gear 1 are provided with teeth 2, and the oblique angle of teeth 2 is a, the angle of a greater than 3.7o less than 4.5o.

Three fourth gear synchronizer gear sleeves of technique scheme, owing to having improved teeth very smooth and easy when making engage a gear, also prevented problem out of supply after the engage a gear, interlock simultaneously performance better, the interlock precision is higher.

Claims

1. have the three fourth gear synchronizer gear sleeves that improve teeth, its ring gear is comprised of inner spline gear, and the two ends of inner spline gear are provided with teeth, and the oblique angle of teeth is a, it is characterized in that: the angle of a greater than 3.7o less than 4.5o.

2. as claimed in claim 1 have three fourth gear synchronizer gear sleeves that improve teeth, and it is characterized in that: described inner spline gear comprises three groups of uniform high teeth and three groups of uniform low teeth, and every group high tooth is adjacent two, and every group low tooth is adjacent three.
