Abstract
The invention discloses a lightweight structure of a cylinder body. The lightweight structure comprises a machine body. A main oil passage is positioned in the machine body, and an oil feeding conduit undergoes press fitting at the oil feeding position of the machine body and is communicated with the main oil passage. The cylinder body with the structure is light in weight and meets the lightweight requirements of an automobile.
Description
Technical field
The present invention relates to cylinder block field, particularly a kind of cylinder block lightweight structure.
Background technique
In the lubricant oil of engine body is supplied with, as depicted in figs. 1 and 2, lubricant oil in body main oil gallery 10 enters cylinder cap through the upper oil hole 30 of body after by the oil groove on camshaft (cam shaft bush hole 20 is only shown in figure), then, the lubricant oil that enters cylinder cap is used for lubricating distribution mechanism.At present, the upper oil hole of the body of cylinder block is all directly in cylinder block, to process both at home and abroad, when casting cylinder block, need to leave at least wall thickness of 5mm (upper oil hole lug) and just can process upper oil hole like this.Meanwhile, consider the impact of the factors such as withdrawing pattern in cylinder block casting technique, reserved actual wall thickness is larger, and the length of upper oil hole is long again, and the overall weight of cylinder block has just increased much like this, cannot meet the automotive light weight technology requirement of increasingly stringent.
The information that is disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Summary of the invention
The object of the present invention is to provide a kind of cylinder block lightweight structure, by cancelling the needed upper oil hole lug of processing upper oil hole in cylinder block, directly with a conduit, be pressed in body and be communicated with main oil gallery, can alleviate greatly the weight of cylinder block, meet the automotive light weight technology requirement of increasingly stringent.
For achieving the above object, the invention provides a kind of cylinder block lightweight structure, comprise body, in body, there is main oil gallery, body oil position press-fit on oil-piping layout, upper oil-piping layout is communicated with main oil gallery.
Compared with prior art, the present invention has following beneficial effect: this structure adopts conduit to be pressed in cylinder block, the upper oil hole lug that needs to process upper oil hole in cancellation cylinder block and stay, thus motor complete machine weight effectively reduced, meet the automotive light weight technology requirement of increasingly stringent.

Main description of reference numerals:
10-main oil gallery, 20-cam shaft bush hole, the upper oil-piping layout of 301-.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.
Unless separately there is other clearly to represent, otherwise in whole specification and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 3 and 4, the cylinder block lightweight structure according to the specific embodiment of the invention, comprises body, has main oil gallery 10 in body, body oil position press-fit on oil-piping layout 301, upper oil-piping layout 301 is communicated with main oil gallery 10.
It should be noted that, main oil gallery 10 and the cam shaft bush Kong20 UNICOM of some types, upper oil-piping layout 301 is press fit into 20 places, cam shaft bush hole, directly from camshaft hole, gets oil; The main oil gallery 10 of some types is directly connected with upper oil duct; The main oil gallery 10 of some types is connected by secondary oil duct and upper oil duct.The above oil duct of the present embodiment is got oil from camshaft hole and is described for example, particularly, in body, there is the main oil gallery 10 and the cam shaft bush hole 20 that interconnect, body oil position press-fit on oil-piping layout 301, upper oil-piping layout 301 is press fit into 20 places, cam shaft bush hole, and upper oil-piping layout 301 is communicated with cam shaft bush hole 20.
The cylinder block lightweight structure that the present embodiment provides is cancelled the upper oil hole casting lug S (referring to Fig. 1) of original cylinder block, directly at body water jacket cavity processing conduit mounting hole, oil-piping layout 301 on press-fiting in the conduit mounting hole of processing, this structure adopts conduit to be pressed in cylinder block, directly lead to camshaft hole and get oil, so just can cancel the upper oil hole lug that needs to process upper oil hole in cylinder block and stay, thereby effectively reduce motor complete machine weight, meet the automotive light weight technology requirement of increasingly stringent.Cancellation need to process upper oil hole and cylinder block after the upper oil hole lug that stays as shown in Figure 3, in Fig. 3, S ＇ represents the outer contour of the upper oil hole lug cancelled.It should be noted that, this structure is not limited to the concrete shape of casting lug, and key is to cancel upper oil hole casting lug, and the technological means that relies on conduit to oil.
The aforementioned description to concrete exemplary of the present invention is for the object with illustration is described.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present invention and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present invention and various selection and change.Scope of the present invention is intended to be limited by claims and equivalents thereof.
Claims (1)
1. a cylinder block lightweight structure, comprises body, in described body, has main oil gallery, it is characterized in that, body oil position press-fit on oil-piping layout, described upper oil-piping layout is communicated with described main oil gallery.
