The utility model discloses with locating pin some as the lubricating oil passageway, the structure has just so effectively been simplified to the locating pin overcoat is equipped with the sealing washer, thereby can realize sealedly reliably.
Description
Technical field
The utility model belongs to motorcycle engine field, particularly relates to the grease channel structure between a kind of cowl hood and cylinder head.
Background technique
Cowl hood and cylinder head are the vitals in motorcycle engine, and after it is assemblied in cowl hood, rocking arm is positioned at cowl hood.In order to ensure that the parts such as rocking arm obtain fully comprehensively lubrication, need specialized designs lubricant oil spraying structure, lubricant oil is transported in cowl hood from crankcase by cylinder block and cylinder head, and sprays to the parts such as rocking arm.Meanwhile, the grease channel Structure of need between cowl hood and cylinder head is simple, and sealing is reliable, proposes the application of this case for this reason.
Model utility content
Technical problem to be solved in the utility model be to provide a kind of structure simple, seal grease channel structure between reliable cowl hood and cylinder head.
The technical solution of the utility model is as follows: the grease channel structure between a kind of cowl hood and cylinder head, comprise cowl hood (1) and cylinder head (2), wherein cowl hood (1) is assemblied in cylinder head (2) top, and be provided with locating stud (3) between cowl hood (1) and cylinder head (2), it is characterized in that: described locating stud (3) is hollow pin, seal ring (4) is set with on locating stud top, sealing circle is contained in the mounting groove of described cowl hood (1) bottom surface, and the bottom surface of seal ring (4) and described cylinder head (2) end face are close to, described cylinder head (2) has the straight oil duct of lubricant oil (2a) and the oblique oil duct of lubricant oil (2b), and lubricant oil straight oil duct upper end is communicated with the lower end of described locating stud (3) center hole, and the straight oil duct of lubricant oil (2a) middle part is communicated with the stud mounting hole on cylinder head (2) by the oblique oil duct of described lubricant oil (2b),
Described cowl hood (1) has lubricant oil inclination oil duct (1a) and the straight oil duct of lubricating oil level (1b), wherein lubricant oil inclination oil duct (1a) lower end is communicated with the upper end of described locating stud (3) center hole, and the upper end of this lubricant oil inclination oil duct is communicated with one end of the straight oil duct of described lubricating oil level (1b).
In said structure, locating stud (3) is designed to hollow pin by the utility model, so just can use the center hole of hollow pin, and it is treated as a part for grease channel, thus reaches the current of simplified structure.Further, locating stud (3) outside is set with seal ring (4), can realize so again reliably sealing, thus prevent oil seepage.
In the present case, the size of described lubricant oil inclination oil duct (1a) and the straight oil duct of lubricant oil (2a) is all less than the aperture of locating stud (3) center hole.
Beneficial effect: the utility model, by the part of locating stud as grease channel, so just effectively simplifies the structure, and is set with seal ring outside locating stud, thus can realize reliably sealing, thus prevent oil seepage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the grease channel structure between a kind of cowl hood and cylinder head, is formed primarily of cowl hood 1, cylinder head 2, locating stud 3 and seal ring 4.Wherein, cowl hood 1 is assemblied in above cylinder head 2, and is provided with locating stud 3 between cowl hood 1 and cylinder head 2.Locating stud 3 is hollow pin, and be set with seal ring 4 on locating stud 3 top, sealing circle 4 is contained in the mounting groove of cowl hood 1 bottom surface, and the bottom surface of seal ring 4 and cylinder head 2 end face are close to.
Cylinder head 2 has lubricant oil straight oil duct 2a and the oblique oil duct 2b of lubricant oil, and the straight oil duct upper end of lubricant oil is communicated with the lower end of locating stud 3 center hole, and is communicated with the stud mounting hole on cylinder head 2 by the oblique oil duct 2b of lubricant oil in the middle part of lubricant oil straight oil duct 2a.Cowl hood 1 has lubricant oil inclination oil duct 1a and the straight oil duct 1b of lubricating oil level, wherein lubricant oil inclination oil duct 1a lower end is communicated with the upper end of locating stud 3 center hole, and the upper end of this lubricant oil inclination oil duct is communicated with one end of the straight oil duct 1b of lubricating oil level.Length direction along the straight oil duct 1b of lubricating oil level is provided with 4 lubricant oil spray-hole 1c.Further, the size of lubricant oil inclination oil duct 1a and the straight oil duct 2a of lubricant oil is all less than the aperture of locating stud 3 center hole.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
