Abstract
The invention discloses a guide rod of a valve bridge. The upper end of the guide rod is provided with a guide segment guiding the valve bridge, and the guide segment is provided with a lubricating oil groove. The lubricating oil can be retained in the guide segment through the lubricating oil groove, the lubricating oil storing function is provided, fine lubrication between the valve bridge and the guide rod can be guaranteed, damage to relevant moving members due to clamping between the valve bridge and the guide rod can be avoided, the lubricating oil groove on the guide rod is easy and convenient to machine, and cost is low.
Description
Technical field
The present invention relates to engine art, particularly a kind of guide rod of air valve bridge.
Background technique
Air valve bridge is bridge shape, and its two ends are respectively equipped with holding cavity, is used to one end of the guide rod that air valve bridge leads to be arranged in the holding cavity of air valve bridge, and the mating part of the two forms guide section.In the process of the upper and lower high-speed motion of air valve bridge, between guide section and holding cavity, be lubricated by lubricant oil, avoid rubbing between the two.In prior art, guide rod is polished rod, in the mutual movement process of air valve bridge and guide rod, lubricant oil easily flows downward or drips, and cannot remain between the two, and therefore lubrication effect is not good, easily there is the catching phenomenon between guide rod and air valve bridge, cause relevant movement parts blocking, unbalance stress, makes the moment stress of movement parts become large and damage movement parts.
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 guide rod of air valve bridge, thereby overcome the not good defect that causes that movement parts is impaired of guide rod lubrication effect of prior art.
For achieving the above object, the invention provides a kind of guide rod of air valve bridge, the upper end of guide rod is provided with the guide section that guiding is provided for air valve bridge, and guide section is provided with oil groove.
Preferably, in technique scheme, oil groove comprises the helical groove that multiple circumferencial directions along guide rod extend.
Preferably, in technique scheme, oil groove comprises the annular groove that at least one circumferencial direction along guide rod extends.
Preferably, in technique scheme, 1/4～3/8 of the height that the total height of oil groove is guide rod.
Compared with prior art, the present invention has following beneficial effect:
Oil groove of the present invention can remain on guide section by lubricant oil, plays oil storage function, guarantees the good lubrication between air valve bridge and guide rod, prevents the damage to relevant movement parts that the catching phenomenon between guide rod and air valve bridge causes; Oil groove processing on guide rod is simple and convenient, and cost is low.
Brief description of the drawings
Fig. 1 is according to the guide rod of air valve bridge of the present invention embodiment's structural drawing.
Main description of reference numerals:
1-guide rod, 11-guide section, 2-oil groove.
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.
Air valve bridge is bridge shape, and its two ends are respectively equipped with the holding cavity that Open Side Down.
As shown in Figure 1, be provided with guide section 11 according to the upper end of the guide rod 1 of the air valve bridge of the specific embodiment of the invention, guide section 11 is contained in the holding cavity on air valve bridge.The total length of guide rod is H.
As shown in Figure 1, on guide section 11, be provided with oil groove 2, lubricant oil flows downward from the upper end of guide rod 1, enter in oil groove 2, oil groove 2 has played storage effect to lubricant oil, air valve bridge carry out along guide rod 1 axially do high-speed motion time, before the inwall of holding cavity and guide section 11, formed the stable oil film of one deck, avoid lubricant oil because gravity falls or flows downward, played good lubrication.
As an embodiment, oil groove 2 comprises the helical groove that one or more circumferencial directions along guide rod 1 extend, as shown in Figure 1.Helical groove can make lubricant oil in helical groove, move in the time being squeezed and can not spill out, and better lubricant oil is retained in oil groove, guarantees the good lubrication between holding cavity inwall and guide rod.
As another embodiment, oil groove 2 comprises the annular groove that multiple circumferencial directions along guide rod 1 extend.Multiple annular recess can remain on guide section by lubricant oil effectively.
As shown in Figure 1, the total height of oil groove is h.Preferably, 1/4～3/8 of the height H that the total height h of oil groove is guide rod, such ratio can ensure the high-efficiency lubricating of oil groove in effective length.
Oil groove of the present invention can remain on guide section by lubricant oil, plays oil storage function, guarantees the good lubrication between air valve bridge and guide rod, prevents the damage to relevant movement parts that the catching phenomenon between guide rod and air valve bridge causes; Oil groove processing on guide rod is simple and convenient, and cost is low.
The aforementioned description to concrete exemplary of the present invention is in order to illustrate and the object of illustration.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.
