Description
Technical field
The present invention relates to a kind of internal combustion engine, its crankcase encapsulates the interior room surrounded by wall portion, and its wall portion has lower edge, bent axle
Cylinder is connected on the lower edge with its flange, wherein for connecting interior room and the passage of grease pump is passed through one of wall portion.This can
To be the reciprocating engine of any type of oil circulating lubrication, wherein grease pump aspirates fluid simultaneously by the bottom of crankcase
It is delivered to some different oil sites.
Background technology
It is as usual in the internal combustion engine as known to No. DE4016968A1 and DE202008010222U1 patent documents
Rule are set, in the passage that passage terminates in the lower end of wall portion and is hermetically passed through in bent axle cylinder.The subsequent passage is towards bent axle cylinder
Whole part.In DE4016968A1 patent documents only it is simple passage or simplifies the passage represented, and the
DE202008010222U1 patent documents are then local increasingly complex devices.Under any circumstance, bent axle cylinder is structure
Complicated exposed part.Meanwhile the sealing of suction inlet is also problem place, particularly between crankcase lower edge and bent axle cylinder
Sealing can be by image.
US2010/0012075A1 patent documents disclose a kind of internal combustion engine on the downside of it with closed crankcase,
Crankcase accommodates oil storage tank.Wherein, channel protrusions protrude, and the channel protrusions are the one of the oil pump being threaded on crankcase
Part.The danger of suction air thus be present not on crankcase in the suction inlet that the lower section of channel protrusions expands.
A kind of internal combustion engine as known to EP1394371A2 patent documents, its crankcase have bent axle cylinder on the downside of it,
It is furnished with multiple oil pumps in the bent axle cylinder.The shell of pump has the channel protrusions for extending downwardly into oil storage tank and up adjoined
The oil-out of crankcase internal channel.Bent axle cylinder is a kind of higher component of cost, the fluid communication Yi Shougan between crankcase
Disturb.
The content of the invention
It is an object of the present invention to propose a kind of bent axle box structure, with minimum extra consumption can obtain it is simple and into
This relatively low bent axle cylinder, while eliminate other related defects.According to the present invention, ground mould is integrally formed in the wall portion comprising passage
The suction base projected in interior room is made, the suction base is formed by covering wall, side wall and end wall, wherein covering wall and side wall ring around suction
Mouthful, two side is connected to wall portion with being integrally formed, and the lower edge of side wall is affixed on bent axle cylinder.Thus, it is all to be used for aspirating fluid
Part is integrated in crankcase, and bent axle cylinder can be a kind of part simple in construction, and the part is deep made of sheet metal
The working of plastics that stamping or spray form.So as to no longer there is sealing problem.
In a preferable embodiment, aspirating the lower edge of foot wall also can at least partly be affixed on bent axle cylinder, and
Suction inlet is constructed in end wall.
In a preferred embodiment, bent axle cylinder has the flange around extension, to be assembled to the lower edge of crankcase
On, its composition surface is in plane, and bent axle cylinder has supporting rib, in its composition surface is generally aligned in the same plane and is affixed on and takes out
On the lower edge for inhaling pin side wall.Due to bent axle cylinder flange and supporting rib in the same plane, thus can be right in a procedure
It is handled.In the simplest situations, bent axle cylinder is the flat board for having collar flange, but it also can be domed downwards.
In the case of bent axle cylinder is made of the sheet metal, supporting rib can be the projection that deep-draw goes out.
In one preferably embodiment, supporting rib disconnects below end wall, and is consequently formed suction inlet.Thus, manufacture
Suction inlet is formed in operation while bent axle cylinder, and this makes the processing of suction base more simplified and makes bent axle cylinder and suction inlet
The installation of Inner filter net is more easy.
In the further scheme of the present invention, the filter screen in suction inlet is fixed in a particularly simple way：Rectangle filter screen
Edge ring is in the groove of insertion end wall and bent axle cylinder.Thus it can be easy to install and be easy to clean.
In embodiments of the invention, suction base has tower-like protuberance near end wall, and the tower-like protuberance has
Lead to the screw of bent axle cylinder.Thus, the center section of bent axle cylinder can also be fixed and be connected to suction base, and this can improve the placement of bent axle cylinder
And Vibration Cylinder Body can be prevented and made a noise.
