Problems solved by technology

[0002] We know that the material commonly used for the flywheel of automobile gasoline engines is HT250. The machining process is complex, poor weldability and other shortcomings, and it is easy to produce casting surface defects and internal slag inclusions, pores and shrinkage porosity, which shortens the service life of the flywheel, and the probability of ring gear falling off is high, causing serious damage to gasoline engines. damage

Abstract

The invention relates to an automobile gasoline engine flywheel. The automobile gasoline engine flywheel is formed by a flywheel body, a gear ring, a center hole and the like. According to the automobile gasoline engine flywheel disclosed by the invention, the flywheel body and the gear ring are integrated, thus the phenomenon that the gear ring is easy to drop off in the past is prevented, the using safety of an gasoline engine flywheel is increased, and the problems of low strength, poor density, complicated machining and poor welding performance of a traditional HT250 gray iron casting flywheel are improved as the flywheel body is formed by forging and machining 45 steel.

Description

technical field : [0001] The invention relates to an automobile part, in particular to an automobile gasoline engine flywheel. Background technique : [0002] We know that the material commonly used for the flywheel of automobile gasoline engines is HT250. The flywheel body made of this material has the disadvantages of heavy weight, low strength, poor density, complicated machining process, poor weldability, etc., and it is easy to produce casting surface. Defects and internal slag inclusions, pores and shrinkage porosity shorten the service life of the flywheel, and the probability of the ring gear falling off is high, causing serious damage to the gasoline engine. Contents of the invention : [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a flywheel for automobile gasoline engines with high strength, high density, simple processing, and the ability to completely avoid ...
