AI Technical Summary
Existing automotive connecting rod assemblies lack limiting structures during long-term use, which makes the connecting rod cover and connecting rod body prone to misalignment, affecting the stability and lifespan of the transmission operation.
A limiting gasket is set between the connecting rod cap and the connecting rod body, and the positioning is limited by the embedded positioning port structure of the first positioning plate and the second positioning plate. At the same time, an oil distribution groove and an oil injection port are set in the connecting rod body to realize the distribution lubrication of lubricating oil.
It improves the connection stability and smoothness between the connecting rod body and the connecting rod cap, enhances the stability of the vehicle transmission, and improves wear resistance and service life during use through comprehensive lubrication.
