Abstract
The invention discloses an aluminium alloy casting for oil pump bodies and pump covers of gasoline engines, which comprises a shell, a driving shaft cavity, a pressure-limiting valve cavity, a gear chamber pressure cavity, pump cover-mounting threaded holes and pump body-mounting threaded holes, the pressure-limiting valve cavity is located in the middle of the shell, the driving shaft cavity is located on one side of the pressure-limiting valve cavity, the gear chamber pressure cavity is located on the other side of the pressure-limiting valve cavity, the pump cover-mounting threaded holes are located on the shell and close to the driving shaft cavity, and the pump body-mounting threaded holes are located on the shell and close to the gear chamber pressure cavity. The aluminium alloy casting can be effectively matched with the structures of other key parts, and can meet the requirement of oil pumps of gasoline engines in use.
Description
Technical field
The present invention relates to a kind of aluminium alloy castings, particularly a kind of aluminium alloy castings of pump cover of engine oil pump body for gasoline engine.
Background technique
In petrolic engine oil pump assembly, because assembly performance parameter and pump housing pump cover coupling require high, need under engine speed 700-7200rpm condition, realize lubrication flow 17.33-19.5L/min, the technical specifications of pressure release cracking pressure 4.5-5.5bar are so foundry goods and its immanent structure and profile are important spare parts.The casting design of existing pump housing pump cover can not be effectively and the elements such as involute gear, pressure-limit valve, spring force, oil outlet, oil duct flow resistance mate, cause the defectives such as engine oil pump assembly flow and pressure instability.
Summary of the invention
Technical problem to be solved by this invention provides a kind of aluminium alloy castings of pump cover of engine oil pump body for gasoline engine, and effective coupling of itself and other key components and parts structure satisfies the needs that the petrol engine oil pump is used.
For solveing the technical problem, the invention provides a kind of aluminium alloy castings of pump cover of engine oil pump body for gasoline engine, it is characterized in that, it comprises housing, initiatively axocoel, pressure limiting valve pocket, gear constant pressure chamber, pump cover are installed tapped hole, the pump housing is installed tapped hole, the pressure limiting valve pocket is positioned at the centre of housing, initiatively axocoel is positioned at a side of pressure limiting valve pocket, gear constant pressure chamber is positioned at the opposite side of pressure limiting valve pocket, pump cover is installed tapped hole and is positioned on the housing and close initiatively axocoel, and the pump housing is installed tapped hole and is positioned on the housing and close gear constant pressure chamber.
Positive progressive effect of the present invention is: effective coupling of the present invention and other key components and parts structures, satisfy the needs that the petrol engine oil pump is used.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 1, the aluminium alloy castings of pump cover of engine oil pump body for gasoline engine of the present invention comprises housing 1, initiatively axocoel 2, pressure limiting valve pocket 3, gear constant pressure chamber 4, pump cover are installed tapped hole 6, the pump housing is installed tapped hole 7, pressure limiting valve pocket 3 is positioned at the centre of housing 1, initiatively axocoel 2 is positioned at a side of pressure limiting valve pocket 3, gear constant pressure chamber 4 is positioned at the opposite side of pressure limiting valve pocket 3, pump cover is installed tapped hole 6 and is positioned on the housing 1 and close initiatively axocoel 2, and the pump housing is installed tapped hole 7 and is positioned on the housing 1 and close gear constant pressure chamber 4.
Wherein, the diameter equidimension in gear constant pressure chamber and the thickness of involute gear, tooth depth, tooth footpath, sector and flow and flow velocity have formed effective coupling, make gear constant pressure chamber be issued to the smooth and easy outflow of optimum flow and minimum drag in effective vacuum.Spatial volume and the angle of pressure limiting valve pocket have been made design improvement, and spring and spool are formed effective matching, and realize effective automatically pressure limiting and the outflow of stable high voltage oil.Effective coupling of the present invention and other key components and parts structures satisfies the needs that the petrol engine oil pump is used.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
