Method for manufacturing automobile synchronizer bevel gear ring conical surface adhesive epoxy resin carbon fiber

Abstract

The invention discloses a method to prepare epoxy resin carbon fibers for bonding the taper face of the bevel gear ring of an auto synchronizer. The synchronizer bevel gear ring fabricated by the method is capable to overcome the problem of low/unstable value of friction coefficient of the bevel gear ring of any steel-based 20CrMnTi spraying Mo or copper-alloy synchronizer. The method is to bond epoxy resin macromolecule carbon fibers onto the taper face of the bevel gear ring of the auto synchronizer. The detailed process is that a piece of carbon-fiber cloth is impregnated in the epoxy resin macromolecule polymer fluid polymerized twice, and then is bonded onto the inside taper face of the bevel gear ring to make the working face elastic, flexible and high-temperature resisting for achieving a stable friction coefficient. As a result, the hard working-face of the synchronizer is improved, the service life is increased by over two folds compared with existing similar products; in addition, the quality, reliability and safety of the complete set of gearbox of the product are guaranteed, and the product becomes safer and more reliable.

Description

technical field [0001] The invention relates to a preparation method of a new bonding material for a bevel gear ring of an automobile gearbox synchronizer, in particular to a preparation method for bonding an epoxy resin carbon fiber to a bevel ring of an automobile synchronizer, belonging to the field of vehicle mechanical processing. Background technique [0002] The gearbox is an important part of the car, and the synchronizer bevel gear ring is the core component of the gearbox, and its quality directly affects many technical indicators of the car. At present, the bevel gear rings of automobile synchronizers commonly used in the world are made of the following two materials, one is steel-based 20C r m n T i spray M o Synchronizer bevel ring, it is based on 20C r m n T i The special steel is forged, machined, heat treated, body formed, and the cone working surface is sprayed M o The second is the copper alloy synchronizer bevel gear ring, which is mainly made of co...

AI Technical Summary

Problems solved by technology

The current products have the following deficiencies in the design indicators and practical applications: one is the steel-based 20C r m n T i spray M o and copper alloy synchronizer bevel gear ring products are all rare metals and non-ferrous metals. In the production process, there are many production equipment, high energy consumption, high raw material costs, and high production costs; the second is the alloy synchronizer bevel gear ring. The friction working surface is a hard working surface, and the friction coefficient value is low, so the product quality is not stable during use, which directly affects the quality and life of the supporting host of the product; the third is that the quality of the friction coefficient of the synchronizer bevel gear ring is unstable, resulting in The safety of the whole machine is poor, the noise is loud, the emission pollution is serious, etc., the work efficiency is low, the product scrap rate is high, and the waste is serious
