Abstract

The invention provides an oil sump connection device for an internal combustion engine. The oil sump connection device is used for connecting an oil sump onto the bottom face of an air cylinder body,and comprises a rubber cushion, a connecting bolt, an upper damping cushion, a lower damping cushion and a polyurethane buffering body; the rubber cushion is arranged in a sealing groove of the oil sump, and the upper end of the rubber cushion extends out of an upper opening of the sealing groove to abut against the bottom face of the air cylinder body; the connecting bolt penetrates through a through hole and the sealing groove of the oil sump to be connected to the air cylinder body; the upper damping cushion is arranged on a positioning shaft of the connecting bolt in a sleeving mode and mounted in the through hole; the lower damping cushion is arranged on the positioning shaft in a sleeving mode, and the lower end of the lower damping cushion abuts against a flange at the head of the connecting bolt; and the polyurethane buffering body is arranged on the positioning shaft in a sleeving mode and located between the upper damping cushion and the lower damping cushion. According to the oil sump connection device for the internal combustion engine, vibration transmission between the oil sump and the air cylinder body can be effectively blocked, radiation noise on the surface of theoil sump is lowered, and thus noise in the whole internal combustion engine is lowered.

Description

technical field [0001] The invention relates to an oil pan connection device for an internal combustion engine, in particular to an oil pan connection device for an internal combustion engine. Background technique [0002] The oil pan is the lower half of the crankcase, and the crankcase seal is used as the casing of the oil storage tank, and the radiated noise on the surface of the oil pan has become an important restrictive factor for reducing engine noise. [0003] The published patent CN201721449144.0 discloses an oil pan connecting device, which is used to connect and install the oil pan on the bottom surface of the cylinder block. A sealing groove is provided on the connecting end surface of the outer flange of the oil pan. The bottom of the tank is provided with a through hole, and the bottom surface of the cylinder block is provided with a threaded hole aligned with the through hole. The oil pan connection device includes: a rubber pad, which is used to be placed in ...
