Abstract
The invention provides a reinforcing structure for the engine oil pan bottom. The reinforcing structure comprises a pan body. The outer bottom portion of the pan body comprises a first end face and a second end face higher than the first end face. The second end face is provided with protrusions and reinforcing ribs. The reinforcing ribs are distributed around the protrusions in an X-shaped mode. The pan body is provided with a connecting reinforcing rib connecting the first end face and the second end face. According to the reinforcing structure for the engine oil pan bottom, the outer bottom portion of the pan body is provided with the end faces different in height and the various reinforcing ribs, the mechanical strength of the whole engine oil pan can be effectively improved, and the problems of deformation, oil leakage, flying-stone impact damage, resonance generated with a car body, noise and the like caused by the insufficient strength can be prevented.
Description
Technical field
The present invention relates to a kind of engine components and manufacture field, relate in particular to a kind of engine sump tank bottom and strengthen structure.
Background technique
Automobile engine oil pan is positioned at engine bottom, dismantled and assembled, and effect is to seal crankcase as the shell of oil storage tank, prevents that impurity from entering.The former fabricated metals that mostly is of engine sump tank, for reducing costs the oil sump that has now occurred plastic cement material, thereby makes oil sump have the shortcoming of insufficient strength, in the process of Vehicle Driving Cycle, easily there is deformation, and then cause oil sump poorly sealed, easily reveal.What after oil sump deformation, produce produces resonance with car body, causes noise very large, is one of main source of engine noise.And the shock of slungshot to oil sump, easily causes the breakage of oil sump in vehicle traveling process, threaten driver's personal safety.In order to strengthen the intensity of oil sump, oil sump is all designed with reinforcement structure on oil sump inside and sidewall, but the significance of having ignored the reinforcement structure of oil sump outer bottom, at oil sump outer bottom, set up reinforcement structure, can obviously strengthen the mechanical strength of oil sump, prevent oil sump deformation, reduce slungshot and clash into the damage to oil sump.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of engine sump tank bottom and strengthen structure, by end face and the multiple stiffening rib of different heights are set at oil sump outer bottom, can effectively strengthen the mechanical strength of whole engine sump tank, thereby prevent because of distortion that insufficient strength causes, leakage of oil, produce with car body the generation that resonance produces the problems such as noise and slungshot impact damage.
The object of this invention is to provide a kind of engine sump tank bottom and strengthen structure, comprise housing, described housing outer bottom comprises the first end face and second end face of height higher than the first end face, on the second end face, be provided with projection and stiffening rib, stiffening rib is ' X ' type and is distributed in around projection, is provided with the connection strengthening rib that connects the first end face and the second end face on housing.
Further improvement of the present invention is: the short stiffening rib that is provided with level on described the first end face.
Further improvement of the present invention is: the linearly or curve-like of described stiffening rib.
Further improvement of the present invention is: on described the second end face and the first end face, be provided with strip rib, strip rib and stiffening rib, connection strengthening rib, short stiffening rib are staggered into latticed.
Further improvement of the present invention is: the height of described stiffening rib, connection strengthening rib, short stiffening rib, strip rib is less than 9mm.
Beneficial effect of the present invention: by end face and the multiple stiffening rib of different heights are set at oil sump outer bottom, can effectively strengthen the mechanical strength of whole engine sump tank, thereby prevent because of distortion that insufficient strength causes, leakage of oil, the generation that produces the problems such as resonance with car body, effectively prevent oil sump deformation, reduce slungshot and clash into the damage to oil sump, reduce engine noise; And the height of stiffening rib is less than 9mm, is easy to processes.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is plan view of the present invention.
Wherein: 1-housing, 2-the first end face, 3-the second end face, 4-projection, 5-stiffening rib, 6-connection strengthening rib, the short stiffening rib of 7-, 8-strip rib.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As depicted in figs. 1 and 2, the present embodiment provides a kind of engine sump tank bottom to strengthen structure, comprise housing 1, described housing 1 outer bottom comprises the first end face 2 and second end face 3 of height higher than the first end face 2, on the second end face 3, be provided with projection 4 and curvilinear stiffening rib 5, stiffening rib 5 is ' X ' type and is distributed in around projection 4, and curve-like stiffening rib 5 makes to increase the stiffening effect of mechanical strength.Projection 1 rear and front end, right side on housing 1 is provided with the connection strengthening rib 6 that connects the first end face 2 and the second end face 3.On described the first end face 2, be provided with the short stiffening rib 7 of level.On described the second end face 3 and the first end face 2, be provided with strip rib 8, strip rib 8 is staggered into latticed with stiffening rib 5, connection strengthening rib 6, short stiffening rib 7.The height of described stiffening rib 5, connection strengthening rib 6, short stiffening rib 7, strip rib 8 is 9mm.
The present embodiment is by arranging end face and the multiple stiffening rib of different heights at housing 1 outer bottom, can effectively strengthen the mechanical strength of whole engine sump tank, thereby prevent because of distortion that insufficient strength causes, leakage of oil, produce with car body the generation that resonance car body produces the problems such as resonance, effectively prevent oil sump deformation, reduce slungshot and clash into the damage to oil sump, reduce engine noise; And the height of stiffening rib is less than 9mm, is easy to processes.
