Abstract
The utility model discloses an oil pan applied in the field of automobile engines, which includes an oil pan body, wherein an oil inlet is arranged in the oil pan body; and a steel tube is inserted at the oil inlet. The oil pan has the technical effects that the mechanical strength of the oil inlet in the oil pan is enhanced, the interior structure of the oil pan is simplified, the machining difficulty is reduced, and the noise reduction in the traveling process of an automobile is facilitated.
Description
Technical field
The utility model relates to a kind of oil sump that is used for the motor car engine field.
Background technique
Oil sump is positioned at the motor bottom: dismantled and assembled, and will be by the shell of axle box sealing as oil storage tank.Oil sump is the Lower Half of crankcase, is again lower crankcase.Effect be the sealing crankcase as the shell of oil storage tank, prevent that impurity from getting into, and collect and store the lubricant oil that flows back to by each friction surface of diesel engine that non-dramatic song part heat prevents oil ageing.Oil sump is many to be stamped to form by sheet metal, also has plenty of with the aluminum alloy cast molding.On the oilcan of the said end filler opening is set, traditional oil sump filler opening normally gets out through the method for machining, and this design causes casting structure complicated, disadvantages such as processing technology complicacy.Because the mechanical strength of filler opening is not enough, in vehicle traveling process, produce very big noise simultaneously, produced the severe noise pollution, this does not meet the requirement of energy-saving and emission-reduction.
The model utility content
The purpose of the utility model is in order to overcome the deficiency of existing technology, a kind of oil sump to be provided, and this oil pan structure is simple, and the mechanical strength of filler opening is high, and can avoid automobile to produce noise pollution in the process of moving.
A kind of technological scheme that realizes above-mentioned purpose is: a kind of oil sump, comprise housing, and on the said housing filler opening is set, said filler opening place's grafting steel pipe.
Further, said steel pipe stretches into the inboard end of said housing, and the circumference of the said steel pipe in edge is provided with boss.
Further, said housing is a foundry goods.
Further again, said steel pipe is a stamping part.
Adopted the technological scheme of a kind of oil sump of the utility model, i.e. filler opening place grafting steel pipe on said housing.Its technique effect is: strengthened the oil sump filler opening mechanical strength, simplified the oil sump internal structure, reduced the difficulty of machining, and helped alleviating the noise in the vehicle traveling process.
Description of drawings
Fig. 1 is the plan structure schematic representation of a kind of oil sump of the utility model.
Fig. 2 is the A-A face sectional view of Fig. 1.
Embodiment
See also Fig. 1 and Fig. 2, the utility model in order to understand the technological scheme of the utility model better, below through embodiment particularly, and combine accompanying drawing at length to explain:
A kind of oil sump of the utility model; Comprise housing 1, a filler opening 11, said filler opening 11 are set on the said housing 1; Grafting steel pipe 2 on the said filler opening 11; Strengthened like this oil sump filler opening 11 intensity, simplified the oil sump internal structure, reduced the difficulty of machining, and can help alleviating the noise in the vehicle traveling process.
Said steel pipe 2 stretches into an end of housing 1 inboard of said oil sump, and the circumference of the said steel pipe 2 in edge is provided with boss 21.The external diameter of said boss 21 can prevent like this that greater than the external diameter of said steel pipe 2 said steel pipe 2 filler opening 11 from said housing 1 under the bigger situation of temperature variation from coming off.
The steel pipe 2 of said oil sump and the inserting mode of said oil sump are: the some through holes that run through said pattern housing of processing on the pattern of the said oil sump of processing, and the position of said through hole is corresponding with the position of the housing of said oil sump 1 the above filler opening 11; The inner chamber core that to process said oil sump is again put into the die cavity of said pattern; Then, steel pipe inserts the through hole on the said pattern housing, and runs through said inner chamber core; Carry out the casting of molten metal then; After waiting said molten metal cooled and solidified at last, remove said inner chamber core and said pattern, obtain a kind of oil sump of the utility model.What the technology that such production technology gets out than the method through machining was come is more prone to.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
Claims (4)
1. an oil sump comprises housing (1), and filler opening (11) is set on the said housing (1), it is characterized in that: said filler opening (11) steel pipe (2) of locating to peg graft.
2. a kind of oil sump according to claim 1 is characterized in that: said steel pipe stretches into the inboard end of said housing (1), and the circumference of the said steel pipe in edge (2) is provided with boss (21).
