Embodiment Construction

[0014] Set forth below the synchronizer ring structure of the present invention and the detailed manufacturing process:

[0015] Such as figure 1 The synchronizer gear ring shown has an annular gear ring base 1 made of metal, and the metal material is usually steel. Carbon fiber cloth 2 is bonded to the inner peripheral wall of the gear ring base 1 (some specifications of synchronizer gear rings are on the outer peripheral wall of the gear ring base).

[0016] The manufacturing method of the synchronizer gear ring includes two steps: a bonding process and a curing process.

[0017] The specific process of the bonding process is as follows:

[0018] (1) Apply glue on both sides of the carbon fiber cloth, the glue content of the glue is 23%-28% (weight content);

[0019] (2) Dry the carbon fiber cloth. After drying, the warp and weft yarns in the carbon fiber cloth can be glued together.

[0020] (3) Cutting the carbon fiber cloth, the size of the cut carbon fiber cloth is c...

Abstract

The invention relates to a manufacturing method of a synchronizer tooth link, which is provided with an annular tooth link base body made of metal materials, wherein carbon fiber cloth is bonded on the peripheral wall surface of the inner side or the outer side of the tooth link base body. The manufacturing method of the synchronizer tooth link comprises the work procedures of: bonding the carbonfiber cloth to the peripheral wall surface of the inner side or the outer side of the tooth link base body and curing, wherein the curing procedure comprises the processes of procuring for 25-40 minutes at 75 to 85 DEG C, gelatinizing for 80-100 minutes at 120 to 150 DEG C and postcuring for 80-100 minutes at 150 to 220 DEG C which are carried out in sequence without stop. The curing procedure can greatly increase the yield of products.

Description

technical field [0001] The invention relates to a manufacturing method of a synchronizer gear ring. Background technique [0002] Generally, the gearbox of a car is equipped with a synchronizer. Its main components include a synchronous gear ring, an adapter sleeve, etc. When shifting, the two-axis gears are at both ends of the synchronized gear ring. The gears of the shaft lean against one side of the block and cannot be synchronized. Due to the force generated by the contact between the block and the gear, the force can make the speed of the high-speed gear tend to decrease, and the speed of the low-speed gear tends to increase until the two sides The speeds of the two gears are equal, and then the two teeth enter the guide groove between the two wedges at the same time, and the gear is changed. [0003] Early synchronizer rings were made of hard copper. Although the synchronizer can meet the requirements of use, it is not strong enough to break easily, has low life and p...
