To hole and air valve bridge guide rod, wherein air valve bridge pilot hole is for installing air valve bridge guide rod.By being fixed in cylinder head
Air valve bridge guide rod, so that air valve bridge can only move up and down, without having lateral sliding, anti-air-stop gate is generated by lateral force
Eccentric wear.
The air valve bridge structure as disclosed in patent CN203532082U, but due to being influenced by arrangement space, valve
The length of fit of bridge and guide rod is often shorter so that guiding role is not obvious, and current air valve bridge pilot hole plus
Work mode is first to carry out thick hinge to be finish reamed again.The diameter in smart school is exactly fit dimension.And the hole slightly cut with scissors is than the hole depth 2 finish reamed
To 4 millimeters, also outline is a little bit smaller for diameter.And guide rod is at work, can only finish ream in hole, and misses since machining exists
Difference also wants distance to finish ream 2 to 3 millimeters of bore edges.Which results in have in air valve bridge pilot hole it is a bit of cannot be used for being oriented to,
It is a kind of waste to vertical space, the space utilization rate for causing air valve bridge pilot hole is lower.Therefore, the present invention is in the patent
Air valve bridge structure on the basis of carried out innovative research and improvement, so that it is increased to develop a kind of guiding length of fit
Air valve bridge.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
The purpose of the present invention is to provide a kind of increased air valve bridges of guiding length of fit, can increase guiding cooperation length

Bridge guide rod, which is characterized in that the bottom of air valve bridge pilot hole is provided with reaming in air valve bridge, and the diameter of reaming is big in air valve bridge
In the diameter of air valve bridge pilot hole, so that air valve bridge guide rod can extend into air valve bridge in reaming.
In a preferred embodiment, the diameter of reaming is 0.2mm bigger than the diameter of air valve bridge pilot hole in air valve bridge.
In a preferred embodiment, the depth of reaming is 5-7mm in air valve bridge.
In a preferred embodiment, air valve bridge oil storage tank is provided on air valve bridge ontology, air valve bridge oil storage tank is used for
Collect the lubricating oil flow down from rocker arm assembly, air valve bridge oil storage tank is connected with reaming in air valve bridge by air valve bridge oil duct
It is logical.
In a preferred embodiment, one end of air valve bridge guide rod is fixed in cylinder head, and air valve bridge can shake
Axis direction under the driving of arm component along air valve bridge guide rod moves down, to press valve.
In a preferred embodiment, air valve bridge guide rod and air valve bridge pilot hole are interference fit.
Compared with prior art, the increased air valve bridge of guiding length of fit according to the present invention has the following advantages that：(1) lead to
It crosses the bottom in air valve bridge pilot hole and devises reaming in air valve bridge, not only increase guiding length of fit, take full advantage of sky
Between, and oil storage space is also added, be conducive to lubricate；(2) it is provided with air valve bridge oil storage tank on air valve bridge ontology, so that valve
Bridge oil storage tank can collect the lubricating oil flow down from rocker arm assembly, to collect more lubricating oil, and lubricating oil is defeated
It send to reaming in air valve bridge, so that lubrication is more abundant.
