Embodiment Construction
[0009] The structure of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.
[0010] Split engine oil pan, including main housing, auxiliary housing, gasket, oil drain plug, oil collecting plate and bolts, its structure is: a raised oil storage chamber 1 is provided at one end of the main housing 1 -1. The sub-housing 2 is used as the bottom case of the oil storage chamber and is connected with the main casing by bolts to form an integral oil pan. The gasket 3 and the bolts are used to seal and fasten the main casing and the sub-housing. The oil collecting plate 4 is welded in the sub-housing, and the oil drain screw plug 2-1 is placed on the bottom of the sub-housing.
[0011] The main shell is a casting; the secondary shell is a stamping. Arc grooves 1-2 are cast in the length direction of the main shell; triangular grooves 1-3 are cast in the width direction; reinforcing ribs 1-4 are cast out...

The invention discloses a split type engine sump. The split type engine sump is structurally characterized in that a protruding oil storage cavity is formed in one end of a main sump body, an auxiliary sump body serves as an oil storage cavity sump to be connected with the main sump body through bolts to form the whole sump, the main sump body and the auxiliary sump body are sealed and fastened through a sealing pad, an oil collection board is welded to the interior of the auxiliary sump body, and a drain plug is arranged at the bottom of the auxiliary sump body. The main sump body is an aluminum casting. The auxiliary sump body is a stamped piece and serves as a main oil tank. Due to the arrangement of the protruding oil storage cavity of the main sump body, the length of an original main sump body is kept unchanged, the oil storage capacity is increased, and the depth of the auxiliary sump body is relatively reduced. The oil collection board is additionally arranged so that it can be guaranteed that an oil suction disc is located below an oil level all the time in the whole vehicle traveling process and a transmission component of an engine can be lubricated normally. An arc-shaped grove, triangular grooves and reinforcing ribs are cast to the main sump body, the heat dissipation area of the sump is increased, the good heat dissipation effect of engine oil can be guaranteed, and vibration and noise are lowered.
Description
technical field [0001] The invention belongs to engine accessories, in particular to an oil pan for a diesel engine. Background technique [0002] The oil pan is one of the main parts of the engine. It is set at the bottom of the car engine, and its main function is to collect oil and cool it. Due to the prolongation of the continuous working time of the engine, the temperature of the oil in the body is also rising. Sometimes there will be oil leakage from the crankshaft oil seal, the connection between the oil pan and the body, and the oil drain plug. More importantly, there are various types of diesel engines, and the structural differences of the chassis are also relatively large, which also leads to various forms of oil pans. However, the design principle of the oil pan is to ensure the capacity of the engine oil as the premise, and consider the heat dissipation of the oil. The more important thing is that it cannot interfere with other components on the engine chassis...
