Noise reduction oil pan with transverse partition plate

The invention relates to a noise reduction oil pan with a transverse partition plate. The noise reduction oil pan is composed of an oil pan body and the transverse partition plate, wherein the oil panbody is connected with the transverse partition plate through welding, energy can be attenuated and reflected after sound waves impact the transverse partition plate, the oil pan body is made of a sandwich composite damping steel plate composed of a steel plate, macromolecular damping glue and an inner-layer steel plate, stamping ribs are arranged at the bottom and the side faces of the oil pan body correspondingly, stamping ribs are arranged on the plane of the transverse partition plate, and welding feet are bent on the periphery of the transverse partition plate. According to the oil pan,a crankcase is sealed to serve as a shell of an oil storage tank, the transverse partition plate is used for increasing the rigidity of an oil pan assembly, the purpose of improving noise is achieved,by adding the oil pan tran
