Lubricating oil can be supplied mutually.
In another embodiment of the present utility model particularly preferably, before guaranteeing rocker arm shaft rigidity and intensity
Put, the circumferential side wall of rocker arm shaft body 1 had both been formed the oil storage tank 5 of above-mentioned annular, has been also formed with linear oil storage
Groove 5.
Especially, in most preferred embodiment of the present utility model, oil storage tank 5 also connects with rocker arm shaft installing hole 2.Make
The lubricating oil that must be flowed out by rocker arm shaft installing hole 2 can flow in each axle lubrication hole 3 by oil storage tank 5, can also keep away simultaneously
The rocker arm shaft insufficient lubrication exempting from the blocking of the oil leab 4 within rocker arm shaft and cause.In other words, even if inside rocker arm shaft
The blocking of oil leab 4, lubricating oil also can be flowed in each axle lubrication hole 3 by oil storage tank 5 so that rocker arm shaft obtains all the time
Lubrication, it is to avoid the risk of the lubrication failure that rocker arm shaft produces.In preferred implementation of the present utility model, oil storage tank 5 is along shaking
Arm axle body 1 axial arranged, the two ends of oil storage tank 5 lay respectively at the both sides of rocker arm shaft installing hole 2.
In order to ensure the intensity of rocker arm shaft, should not be provided with on rocker arm shaft body 1 and multiple to connect with rocker arm shaft installing hole 2
Oil leab 4, therefore, especially, all sidewalls of rocker arm shaft body 1 is additionally provided with the circumferentially extending profit along rocker arm shaft body 1
Chute 6.Make to arrange lubrication groove 6 on the relevant position needing lubrication so that the lubricating oil of unnecessary spilling on rocker arm shaft body 1
Can flow in lubrication groove 6, and make relevant position obtain lubrication.
Especially, multi-oil-passage rocker arm shaft also includes that hydraulic valve performs oil duct 8, and hydraulic valve performs oil duct 8 and installs with rocker arm shaft
Hole 2 connects.Wherein, the Main Function of hydraulic valve execution oil duct 8 is the executor's fuel feeding to rocker arm-braking, to realize hydraulic valve
Driving.Connect with rocker arm shaft installing hole 2 by hydraulic valve being performed oil duct 8 so that flow through the lubricating oil of rocker arm shaft installing hole 2
It is partially into hydraulic valve and performs in oil duct 8, to realize the executor's fuel feeding to rocker arm-braking.See Fig. 5, the most visible, hydraulic pressure
Valve performs oil duct 8 and includes larger-size oil-feed section and less fuel-displaced section of size.
It is particularly preferred that with continued reference to Fig. 5, oil leab 4 is communicated in hydraulic valve and performs oil duct 8.Specifically, one of them
The oil-feed section that oil leab 4 performs oil duct 8 with hydraulic valve connects so that perform the oil-feed section of oil duct 8 wherein by hydraulic valve
Fuel feeding in one oil leab 4, is equally reached rocker arm shaft and obtains the effect of lubrication all the time.Even if in rocker arm-braking function not
In the case of unlatching, rocker arm shaft still can effectively be lubricated, thus reduces the mistake that rocker arm shaft causes because of lack of lubrication
Effect.
It addition, this utility model additionally provides a kind of brake unit, brake unit includes rocking arm and rocker arm bracket, brake unit
Also including above-mentioned rocker arm shaft, rocker arm shaft is by running through being bolted on rocker arm bracket of rocker arm shaft installing hole 2, and rocking arm is set in
On rocker arm shaft body 1, and being rotationally connected with rocker arm shaft body 1, axle lubrication hole 3 is arranged on the rocker arm shaft being rotatably assorted with rocking arm originally
In the circumferential side wall of body 1.The lubricating oil flowed out by rocker arm shaft installing hole 2 is entered in oil leab 4, and by axle lubrication hole
3 flow in the gap that rocking arm coordinates with rocker arm shaft, to reach to lubricate the purpose of rocker arm shaft.Even if making rocker arm-braking function not open
Qi Shi, i.e. controls do not have lubricating oil to flow through in oil hole, and rocker arm shaft can also the most sufficiently be lubricated, thus decrease by
The rocker arm shaft caused in lack of lubrication lost efficacy.Wherein, rocker arm shaft installing hole 2 is bolt mounting holes.
This utility model by axle lubrication hole 3 being opened in the circumferential side wall of the rocker arm shaft body 1 that rocking arm is rotatably assorted,
The oil duct that oil leab 4 and control for brake oil hole 7 are formed works alone, and is independent of each other, i.e. either rocker arm-braking merit
Whether have lubricating oil flow through, all can be real if can be in braking opening still brakes off state, i.e. control for brake oil hole 7
The most effectively lubricate.It is particularly preferred that this brake unit can be arranged on the engine.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing, but, this utility model does not limit
Detail in above-mentioned embodiment, in technology concept of the present utility model, can be to skill of the present utility model
Art scheme carries out multiple simple variant, and these simple variant belong to protection domain of the present utility model.
It is further to note that each the concrete technical characteristic described in above-mentioned detailed description of the invention, at not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, this utility model is to respectively
Plant possible compound mode to illustrate the most separately.
Additionally, combination in any can also be carried out, as long as it is not disobeyed between various different embodiment of the present utility model
Carrying on the back thought of the present utility model, it should be considered as content disclosed in the utility model equally.
