Die-casting aluminum flywheel casing

Abstract

The invention belongs to the technical field of flywheel shells, and particularly relates to a die-casting aluminum flywheel shell which comprises a shell body, a reinforcing plate is welded to one side of the shell body, an oil hole is formed in one side of the shell body, a connecting end is arranged on the oil hole, an oil pipe connecting hole is formed in the oil hole, and a mounting connecting plate is welded to one side of the reinforcing plate. A plurality of mounting holes are formed in one side of the mounting connecting plate, a plurality of first reinforcing strips are welded to the outer ring of the shell, first connecting fixing plates are welded to the sides, close to each other, of the first reinforcing strips, a crankshaft hole is formed in one side of the shell, a wheel groove is formed in one side of the shell, and a reinforcing table is welded to one side of the wheel groove; second reinforcing strips are welded to one side of the reinforcing table, and second connecting fixing plates are welded to the sides, close to each other, of the second reinforcing strips. The overall design is reasonable, operation is easy, the weight burden is effectively relieved, the overall structure is firm, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of flywheel housings, in particular to a die-cast aluminum flywheel housing. Background technique [0002] The flywheel housing is installed between the engine and the gearbox, externally connected to the crankcase, starter, oil pan, and built-in flywheel assembly, which plays the role of connecting the body, protection and carrier. Its main function is to achieve effective connection between the engine and the transmission, Through its changes, the same type of engine can be equipped with different types of cars to meet market demand. [0003] However, at present, the vast majority of flywheel housings used in diesel engines are cast iron, with thick walls, resulting in poor fluidity during casting and the formation of "trachoma"; large volume and weight increase the weight of the engine itself; high processing costs, casting The surface is rough and unsightly. Therefore, a die-cast aluminum flywheel housi...

Problems solved by technology

[0003] However, at present, most of the flywheel shells used in diesel engines are made of cast iron, with thick walls, resulting in poor circulation during casting and the formation of "trachoma"; large volume and heavy weight, which increase the weight of the engine itself; high processing costs, casting The surface is rough and unattractive. For this reason, a die-cast aluminum flywheel housing is proposed
