Material formula for automobile constant speed driving shaft

Abstract

The invention relates to a material formula for an automobile constant speed driving shaft. The material formula comprises, by weight, 25-45 parts of carbon steel, 15-25 parts of carbon fibers, 5-13 parts of potassium permanganate, 15-18 parts of manganese dioxide, 3-7 parts of barium chloride, 8-16 parts of molybdenum dioxide, 1-2 parts of tin, 2-6 parts of magnesium oxide, 13-26 parts of aluminum oxide, 18-24 parts of silicon carbide and 10-22 parts of iron oxide. According to the formula provided by the invention, the driving shaft is produced out according to the proportion of the carbon steel, the carbon fibers, the potassium permanganate, the manganese dioxide, the barium chloride, the molybdenum dioxide, the tin, the magnesium oxide, the aluminum oxide, the silicon carbide and the iron oxide, and the heat dissipation performance is very good; and when the driving shaft operates under the condition that high temperature is produced in a long-time friction state, heat energy stored in the driving shaft can be rapidly dissipated, and the defect produced by heat fatigue is overcome, so that the service life of the driving shaft is prolonged.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to the material formulation of a constant-velocity drive shaft for an automobile. Background technique [0002] The constant speed drive shaft of the car is in a rotating state. Generally, the fixed part with the base will be subject to a lot of friction, which will generate a lot of heat energy and store it on the drive shaft itself. Since the heat energy cannot be dissipated in time, it is easy to cause the drive shaft to If thermal fatigue occurs, the drive shaft is easily scrapped, reducing its service life and wasting a lot of resources and costs. Contents of the invention [0003] According to the deficiencies of the prior art, the present invention provides a material formulation of a constant velocity drive shaft for automobiles that improves the heat dissipation performance of the drive shaft. [0004] The present invention is achieved in this way, the material formul...
