An engine flywheel housing assembly structure

Abstract

The invention discloses an engine flywheel shell assembly structure. The engine flywheel shell assembly structure comprises a shell body base plate, a shell body faceplate and a sealing plate. The shell body faceplate is installed on the shell body base plate through a locating pin, the sealing plate is installed on the shell body base plate through a cylindrical pin, an oil returning groove is formed in the shell body faceplate, and a leakage-proof assembly is arranged at the position, corresponding to the oil returning groove, of the sealing plate. The leakage-proof assembly comprises a base plate and an auxiliary plate, the auxiliary plate is arranged on the edge of the base plate and locked on the sealing plate through a dowel, the base plate is provided with at least one sealing strip through a buckling ring, and the top of the base plate is provided with a locating protrusion. According to the engine flywheel shell assembly structure, the structure is reasonable, the method that the shell body base plate and the shell body faceplate are assembled in a split mode is adopted by a flywheel shell, the situation that the flywheel shell overall cracks due to crack extending is reduced effectively, assembling is simple and fast, the engine flywheel shell is durable, and the phenomenon that the engine performance is influenced by oil leakage can be avoided effectively; and the flywheel shell is convenient to use and practical, and the operability is high.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an assembly structure of an engine flywheel housing. Background technique [0002] As an important engine component, the flywheel housing is installed between the engine and the gearbox, externally connected to the crankcase, starter, oil pan, built-in flywheel housing assembly, gear chamber system, etc., to connect the body, protection and carrier role. During the use of the flywheel housing, due to the influence of gravity, external force and irregular vibration, etc., cracks are prone to occur. As the cracks expand and extend, the overall cracking of the flywheel housing may be caused, and the service life is short, making the flywheel housing The quality directly affects the performance of the engine, and there may be oil leakage, which directly affects the sealing and lubricity of the engine, and the stable operation of the engine cannot be guaranteed. [0003] Therefore, ...
