Description

Oil pan and vehicle

Technical Field

The invention relates to the field of engines, in particular to an oil pan, and further relates to a vehicle comprising the oil pan.

Background

The oil pan of the engine is mainly used for storing engine oil and also plays a role in protecting other parts of an engine lubricating system.

The traditional oil pan is generally an integrated structure formed by stamping and molding a thin steel plate, and although the structure is simple, the requirement on the arrangement space of an engine is high. Generally, a fan is assembled on a crankshaft of an engine, the rotating speed of the fan is constant, the heat dissipation capacity is limited, an ideal heat exchange effect cannot be achieved, and the water temperature of the engine is high. In order to solve the problem, the rotating speed of the fan needs to be increased to improve the heat exchange efficiency, generally, the installation position of the fan is increased to increase the transmission ratio of the fan and improve the rotating speed of the fan, so that the heat exchange capacity is improved. However, since the mounting position of the fan and the vehicle radiator is fixed, it is necessary to reduce the height of the oil pan to compensate for the increased height of the fan.

Secondly the oil pan structure of traditional integral type makes its intensity not enough, and at the vehicle in-process of traveling, easy deformation leads to the oil pan to seal not tight to the problem of engine oil leakage appears. In addition, in a diesel engine with a large cylinder diameter, noise caused by vibration of an oil pan due to high-frequency vibration of the engine is very large, and is one of the main sources of engine noise.

Therefore, how to provide an oil pan which is convenient to arrange and has high strength is a technical problem which needs to be solved urgently by the technical personnel in the field.
