Abstract
The utility model discloses an air cylinder cover lubricating oil channel structure of an automobile engine. The bottom end of a straight oil duct is communicated with an oil outlet of an air cylinder body, an air cylinder pad is arranged between the straight oil duct and the oil outlet of the air cylinder body, the top end of the straight oil duct is connected with a bearing cover by a screw nail, the top end of the straight oil duct is compacted with the bottom face of the bearing cover, and a nail rod structure of the screw nail enters an inner hole of the straight oil duct after penetrating through a hole on the bearing cover. By adopting the structural design of the straight oil duct, the hollow screw nail, a bearing cover oil tank and the like, the air cylinder cover lubricating oil channel structure has the advantages of simple technique, compact structure, low cost, good lubricating effect and the like. Therefore, the lubricating oil channel arrangement suitable for the automobile engine with small discharge capacity is realized.
Description
Technical field
The utility model relates to the cylinder cover of automobile engine lubricating oil path to be arranged, is specially a kind of small displacement engine cylinder head oil circuit and arranges.
Background technique
Automobile with small output volumn engine cylinder cap structure is compact at present, lubricating oil path designs on cylinder cap needs many oblique oil circuits of increase or horizontal oil circuit to guarantee the lubricated of camshaft, the technology that needs on the cylinder cap like this to increase many oil circuit boring is blocked up, because of on cylinder cap, arranging horizontal oil circuit or oblique oil circuit, the casting cost and the machine that have increased the small displacement engine cylinder head add cost, and the lubrication effect of friction pair also is affected.
Summary of the invention
The purpose of this utility model is to provide at the bottom of a kind of cost, and lubricated effectiveness is fit to the lubricating oil path of automobile with small output volumn motor well and arranges.
In order to achieve the above object, the technical solution adopted in the utility model is: straight oil duct bottom is communicated with the cylinder block oil outlet, head gasket is installed between straight oil duct and the cylinder block oil outlet, the top of straight oil duct is connected with bearing cap by screw, the top of straight oil duct and the bottom surface of bearing cap compress, and the hole that the nail bar structure of screw is passed on the bearing cap enters in the endoporus of straight oil duct.
The utility model has the advantages that:
Since the utility model adopted straight oil duct, hollow screw,, structural designs such as bearing cap oil groove make this cylinder head oil circuit arrange to have technology simple, compact structure, advantages such as expense is cheap, and lubricated effectiveness is good, thus the lubricated oil circuit of having realized suitable automobile with small output volumn motor is arranged.
Description of drawings
Fig. 1 is the utility model lubricating oil path layout schematic representation;
Fig. 2 is the utility model bearing cap tank structure partial view.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1 one Fig. 2 as can be known, the straight oil duct of the utility model 3 bottoms are communicated with cylinder block oil outlet 1, head gasket 2 is installed between straight oil duct 3 and the cylinder block oil outlet 1, the top of straight oil duct 3 is connected with bearing cap 4 by screw 5, the top of straight oil duct 3 and the bottom surface of bearing cap 4 compress, and the hole 7 that the nail bar structure of screw 5 is passed on the bearing cap 4 enters in the endoporus of straight oil duct 3.
Have hollow hole 8 in the nail bar structure of screw 5, the bottom of bearing cap 4 has oil groove 6, and straight oil duct 3 is communicated with the oil groove 6 of bearing cap 4 bottoms by the hollow hole 8 of screw 5.
The oil groove 6 of bearing cap 4 bottoms is made up of leading portion straight line oil circuit 9, stage casing circular arc oil circuit 10 and back segment straight line oil circuit 11 3 parts, wherein oil duct is that the head end of the leading portion straight line oil circuit 9 of straight line is communicated with hole 7, the latter end of leading portion straight line oil circuit 9 is communicated with the head end of two oil ducts stage casing circular arc oil circuit 10 that is the quadrant arc respectively, article two, the end of stage casing circular arc oil circuit 10 is communicated with the head end of two oil ducts back segment straight line oil circuit 11 that is straight line respectively, and the end of two back segment straight line oil circuits 11 is communicated with camshaft hole 12 and camshaft hole 13 respectively.
The utility model engine lubricating oil enters camshaft hole 12,13 and finishes lubricated through the flow through oil duct of bearing cap 4 UNICOMs that have oil groove of straight oil duct 3.The bearing cap 4 that has oil groove is a compression fit with cylinder cap, guarantees that lubricant oil arrives camshaft hole 12,13 smoothly.The utility model working procedure is: the lubricant oil that comes from cylinder block enters camshaft hole through head gasket, the straight oil duct of cylinder head, hollow screw, the bearing cap that has an oil groove.
