Description
Technical field
The utility model is related to machine oil sendout technical fields, adjustable more particularly to a kind of engine and machine oil sendout
Oil channel structure.
Background technology
Engine motor oil primarily serves lubrication and cooling two kinds of effects within the engine at present, and machine oil generally passes through lubricating oil pump
And corresponding oil duct is supplied to and needs lubrication and cooling each position.
Engine lubrication is divided into two parts：The components such as bent axle, major-minor shaft gear shafting lubrication (fuselage of engine) and
The distribution system of the components such as camshaft, rocking arm, valve lubricates (engine head), and 25% He is generally pressed in this two parts traditional technology
75% distribution.As engine speed increases, shafting lubrication changes in demand it is smaller, and distribution system lubrication demand change compared with
Greatly.Distribution system lubrication demand in high speed surges, but due to using the distribution limitation of fixed oil mass, distribution system in traditional technology
Component obtains less than more machine oil in high speed, causes distribution component easy to wear.
In addition, the cooling of engine heat engine part (engine head, cylinder head and cylinder body) is particularly important in high speed.It is sending out
When motivation runs at high speed, it is therefore desirable to there are more machine oil to wash away the heat engine part of engine, take away heat, reduce the heat of engine
Load, but due to using the distribution limitation of fixed oil mass in traditional technology, heat engine part obtains less than more in high speed
Machine oil causes the thermic load of engine larger.
Invention content
Based on this, it is necessary to provide a kind of engine and the adjustable oil channel structure of machine oil sendout, which can
The oil channel structure of tune can be supplied using the stifled movement of limit oil oil to increase oil mass when oil pressure increases to a certain extent, to
Improve the lubricant effect and cooling effect of privileged site；The engine uses above-mentioned oil channel structure, and engine is made to be carried in rotating speed
When high, pump oil amount increases, the oil level of entire engine can reallocate, and lubricating oil is more assigned to greater need for machine
The position of oil, it is possible to reduce abrasion of each moving component in high speed, and improve cooling effect, reduce thermic load, it carries significantly
The service life of high engine.
Its technical solution is as follows：
On the one hand, the application provides a kind of adjustable oil channel structure of machine oil sendout, including the first oil duct and described first
The second oil duct that oil duct is connected to each other and limit oil oil are stifled, the limit oil oil is stifled can automatically reset be set to first oil duct and
Between the second oil duct and oily stifled free end of limit oil is arranged towards the fuel-displaced direction of first oil duct, the limit
Oily oil is stifled to be equipped with the oily channel of limit, and the oil inlet in the oily channel of limit is set to the stifled free end of the limit oil oil and with described the
One oil duct communicates, and the oil outlet in the oily channel of limit is communicated with second oil duct；Wherein, when the stifled suffered oil pressure of limit oil oil
When less than or equal to default oil pressure, first oil duct can only be communicated by the oily channel of the limit with the second oil duct；When the limit
When oily stifled suffered oil pressure is more than the default oil pressure, the limit oil oil is stifled between first oil duct and second oil duct
There are gap, first oil duct is communicated by the oily channel of the limit and the gap with the second oil duct；Or when limit oil oil
When stifled suffered oil pressure is more than the default oil pressure, the limit oil oil is stifled to be equipped with flow increasing channel, and first oil duct passes through the limit
Oily channel and the flow increasing channel are communicated with the second oil duct.
The adjustable oil channel structure of said engine oil sendout in use, using oil pressure pressure under various operating modes variation, utilize
The stifled flow realized between the first oil duct and the second oil duct of limit oil oil is adjustable, makes the oil mass being assigned on the second oil duct can basis
The variation of operating mode and be adjusted, meet the lubrication needs and cooling requirement of privileged site.Specifically, machine oil sendout is adjustable
Oil channel structure be applied to engine in, in low speed, engine oil pressure is not enough to overcome reset force, machine oil can only be from limit engine
Oily stifled limit oil channel is flowed through, and entire oil circuit is identical as fixed oil mass distribution at this time, each position oil mass distribution and original machine structure
Equally；When engine speed is increased to specific rotation speeds, the first gallery pressure reaches when can overcome reset force, and machine oil starts to jack up
Limit oil oil is stifled, and after limiting that oil oil is stifled and being jacked up, the limit oil oil is stifled between first oil duct and second oil duct between generation
Gap, machine oil pass through simultaneously from the oily channel of limit and gap；Or and limit oil oil is stifled is equipped with flow increasing channel, first oil duct is logical
It crosses the oily channel of the limit and the flow increasing channel is communicated with the second oil duct, can equally increase the lubrication of the second oil duct and the machine of cooling
Oil mass, to improve the lubricant effect and cooling effect of privileged site.Further, as the oily oil of limit blocks liter, the first oil duct
Oil pressure declines, and the pump oil amount of lubricating oil pump increases, and the engine power of consumption is reduced, and will improve engine power.

As shown in Figure 1, the adjustable oil channel structure 10 of the machine oil sendout, including the first oil duct 100 and the first oil duct 100
The second oil duct 200 for being connected to each other and limit oil oil stifled 300, limit oil oil stifled 300 can automatically reset be set to the first oil duct 100 with
Between the second oil duct 200 and free end 301 of limit oil oil stifled 300 is arranged towards the fuel-displaced direction of the first oil duct 100, limits oil oil
Stifled 300 are equipped with the oily channel of limit, limit oily channel oil inlet be set to limit oil oil stifled 300 free end 301 and with the first oil duct
100 communicate, and the oil outlet for limiting oily channel is communicated with the second oil duct 200；Wherein, when limit oil oil blocks up the first oil is come from suffered by 300
When 100 oil pressure of road is less than or equal to default oil pressure, in the raw, the first oil duct 100 can only be by limiting oily channel for elastic component
It is communicated with the second oil duct 200；When limit oil oil, which blocks up the oil pressure from the first oil duct 100 suffered by 300, is more than default oil pressure, elasticity
Part is compressed, and is limited there are gap 330 between oil oil stifled 300 and the first oil duct 100 and the second oil duct 200, the first oil duct 100 is logical
It crosses the oily channel of limit and gap 330 is communicated with the second oil duct 200；Or the oil pressure suffered by the limit oil oil stifled 300 is when being more than default oil pressure, limit
Oily stifled 300 are equipped with flow increasing channel 320, and the first oil duct 100 is by limiting oily channel and flow increasing channel 320 and 200 phase of the second oil duct
It is logical.
The adjustable oil channel structure of said engine oil sendout 10 in use, using oil pressure pressure under various operating modes variation, profit
With limiting, the flow that oil oil stifled 300 realizes between the first oil duct 100 and the second oil duct 200 is adjustable, makes to be assigned to the second oil duct 200
On oil mass can be adjusted according to the variation of operating mode, meet the lubrication needs and cooling requirement of privileged site.
