Summary:The utility model relates to a rear-mounted bus engine oil sump vibration-insulating structure for reducing vehicle noise, which comprises a sealing gasket and a bolt, wherein the sealing gasket is held between an engine frame and the contact face of an oil sump, and the bolt is employed to connect the engine frame, the sealing gasket and the oil sump as one. The sealing gasket is made from rubber pad, and the upper and the lower surfaces of the rubber pad are respectively provided with two elastic rings which are contacted with the engine frame and the oil sump. The utility model also comprises a vibration isolator which is composed of a mental rubber pad and a mental plate which are mutually overlapped. The vibration isolator is arranged between the lower portion of the folding edge of the oil sump and the projecting mesa at the head of the bolt. The utility model is arranged between the engine frame and the oil sump, which can prevent vibration transmission from the engine frame to the oil sump, thereby the utility model can control the noise radiation of the oil sump to reduce the noise of the overall device by 1dB to 1.5 dB (A).
