This oiling method shunting part flows through the lubricant oil of rocker arm bush, there is shortage of oil on cylinder inner brake, and rocker arm bush insufficient lubrication, break oil pressure drop equivalent risk.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of rocker arm bracket of simple and reasonable cylinder inner brake to oil lubricating structure, the rocker arm bracket of this cylinder inner brake oils the initial position bifurcated of lubricating structure at the upper oil duct of rocker arm bracket, the upper oil hole of cylinder inside brake and lining upper oil hole are separated, the oil mass of grease cylinders inner brake can be made so not shunt the oil mass of lubrication rocker arm bush, ensure rocker arm bush lubricating requirement, also can reduce shortage of oil on cylinder inner brake, avoid break to oil pressure drop equivalent risk.
For achieving the above object, the rocker arm bracket that the utility model provides a kind of cylinder inner brake oils lubricating structure, and the rocker arm bracket of this cylinder inner brake lubricating structure that oils comprises: rocker arm bracket, and it is for supporting pitman arm shaft, and pitman arm shaft is rotated in pitman arm shaft lining; Oil channel hole, it is opened in the side of described rocker arm bracket, keeps being communicated with the main oil gallery of engine lubricating oil; First oil outlet end of this oil channel hole is communicated with lubricant pipe; And lining upper oil hole, its one end is communicated with the second oil outlet end of described oil channel hole, and the other end is communicated to pitman arm shaft lining.
Preferably, in technique scheme, oil channel hole is opened in the right side of rocker arm bracket.
Preferably, in technique scheme, oil channel hole is vertically opened in the right side of rocker arm bracket.
Preferably, in technique scheme, the side of rocker arm bracket offers bolt hole.
Preferably, in technique scheme, bolt hole next-door neighbour oil channel hole is vertically opened in the right side of rocker arm bracket.
Compared with prior art, the utility model has following beneficial effect: the rocker arm bracket of this cylinder inner brake oils the initial position bifurcated of lubricating structure at the upper oil duct of rocker arm bracket, the upper oil hole of cylinder inside brake and lining upper oil hole are separated, the oil mass of grease cylinders inner brake can be made so not shunt the oil mass of lubrication rocker arm bush, ensure rocker arm bush lubricating requirement, also can reduce shortage of oil on cylinder inner brake, avoid break to oil pressure drop equivalent risk.
Accompanying drawing explanation
Fig. 1 is that the rocker arm bracket of cylinder inner brake of the present utility model oils the structural representation of lubricating structure.
Fig. 2 is the sectional structure schematic diagram in the A-A direction of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As depicted in figs. 1 and 2, comprise according to the oil concrete structure of lubricating structure of the rocker arm bracket of the cylinder inner brake of the utility model embodiment: rocker arm bracket 1, and the oil channel hole 2, lining upper oil hole 3 and the bolt hole 4 that are opened in this rocker arm bracket 1, wherein, one end of oil channel hole 2 is communicated with lining upper oil hole 3, and the other end is communicated with lubricant pipe (not shown); Lining upper oil hole 3 is communicated to pitman arm shaft lining, and lubricant pipe is communicated to cylinder inner brake.Engine lubricating oil draws the oil channel hole 2 of oil to pitman arm shaft 1 from main oil gallery, then shunt through lining upper oil hole 3 and lubricant pipe, the upper oil hole of cylinder inside brake and lining upper oil hole are separated, the lubricant oil entering lining upper oil hole 3 is transported to pitman arm shaft lining and lubricates it, and the lubricant oil entering lubricant pipe is transported to cylinder inner brake and lubricates it.The rocker arm bracket of this cylinder inner brake oils the initial position bifurcated of lubricating structure at the upper oil duct of rocker arm bracket, the upper oil hole of cylinder inside brake and lining upper oil hole are separated, the oil mass of grease cylinders inner brake can be made so not shunt the oil mass of lubrication rocker arm bush, ensure rocker arm bush lubricating requirement, also can reduce shortage of oil on cylinder inner brake, avoid break to oil pressure drop equivalent risk.
Specifically, rocker arm bracket 1, for supporting pitman arm shaft, makes pitman arm shaft rotate in pitman arm shaft lining.
Oil channel hole 2 is vertically opened in the right side of rocker arm bracket 1, as the initial position of the upper oil duct of rocker arm bracket, keeps being communicated with the main oil gallery of engine lubricating oil.From main oil gallery, the oil channel hole 2 of oil to pitman arm shaft 1 is drawn to the engine lubricating oil of pitman arm shaft lining and cylinder inner brake lubrication.
One end of lining upper oil hole 3 is communicated with one end of oil channel hole 2, and the other end is communicated to pitman arm shaft lining, and engine lubricating oil draws the oil channel hole 2 of oil to pitman arm shaft 1 from main oil gallery, is then transported to pitman arm shaft lining through lining upper oil hole 3 and lubricates it.
The other end of oil channel hole 2 is communicated with lubricant pipe (not shown); Lubricant pipe is communicated to cylinder inner brake.Engine lubricating oil draws the oil channel hole 2 of oil to pitman arm shaft 1 from main oil gallery, is then transported to cylinder inner brake through lubricant pipe and lubricates it.
Bolt hole 4 is close to the right side that oil channel hole 2 is vertically opened in rocker arm bracket 1, and bolt hole 4 plays the effect of fixing lubricant pipe and rocker arm bracket.
To sum up, the rocker arm bracket of this cylinder inner brake oils the initial position bifurcated of lubricating structure at the upper oil duct of rocker arm bracket, the upper oil hole of cylinder inside brake and lining upper oil hole are separated, the oil mass of grease cylinders inner brake can be made so not shunt the oil mass of lubrication rocker arm bush, ensure rocker arm bush lubricating requirement, also can reduce shortage of oil on cylinder inner brake, avoid break to oil pressure drop equivalent risk.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
