Abstract
The utility model relates to an engine lubricating oil automatic control valve device for controlling working fluid of engines, which efficiently raises the working performance of the engines working in the states of slopes and extends the service lives of the engines. A front and a back oil inlet pipes are communicated with an engine oil pump through an oil outlet pipe in the automatic control valve. A rotatable valve core is arranged in a three-way pipe in the automatic control valve, both ends of the valve core are hinged with supporting frames through the valve body, and the supporting frames are fixedly connected with counterweight swinging balls. The utility model is mainly suitable for various engineering machines working in the states of large slopes.
Description
The utility model relates to a kind of valve, especially engine lubricating oil oil-feed autocontrol valve device that engine working fluid sucks or discharges of controlling.
The engineering machinery that has now in big slope state work mainly comprises bulldozer, rake storehouse machine, tank etc., this class machinery is through the work under the large slope state of being everlasting, some can reach 60 degree angles, and its engine lubrication system utilizes double oil pump or single row machine oil pump to deepen the oil groove device at present mostly.These two kinds of devices work long hours under the large slope state; its oil pump is drawn onto air easily; after entering the oil lubricating system, high-pressure air after the compression of process oil pump forms air shock; particularly at the contour ski-running of bearing shell kinetic friction place destructible oil film; and oil film is protection bent axle, bearing shell, reduces the key of touching friction, and oil film is destroyed by regular gas percussion; then easily strengthen abrasion, easily cause machines such as motor tile kilning, burning bent axle to decrease in the course of time.In addition, be to consider under level, to work during present many engine design, when changing the height-limited system of oil groove when working the rake angle state under into, double pump mounting point is not enough again.The popularity that these have all influenced the life-span of motor and have limited engine application.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and a kind of performance when improving motor and working under the state of slope is provided, and prolongs the motor engine lubricating oil oil-feed autocontrol valve device in working life.
The purpose of this utility model can reach by following measure: this engine lubricating oil autocontrol valve device that relates to suction of control engine working fluid or expulsion valve, have engine oil sump, oil inlet pipe, oil outlet tube, oil pump, oil-feed filter core etc., its special way is; Former and later two oil inlet pipes are communicated with by autocontrol valve, and its oil outlet tube intermediate connection oil pump, valve body and engine body are rigidly connected.
The purpose of this utility model can also reach by following measure: the support that built-in rotatable spool, spool link by valve body and valve body two ends in the three-way pipe that autocontrol valve is communicated with oil outlet tube by forward and backward oil inlet pipe, the three-way pipe, form with the counterweight swing ball that support is affixed.Spool is by rotatable pendulum mass, form with affixed pendulum in pendulum mass upper end or the running shaft in the middle of cylinder and the pendulum mass.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the plan view of autocontrol valve.
Fig. 2 is the plan view of autocontrol valve.
Fig. 3 is the left view of autocontrol valve.
Fig. 4 is an engine lubricating oil oil-feed lubricating system structural representation.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, the preceding oil-feed filter core 2 of oil groove 1 bottom of motor, back oil-feed filter core 21 are communicated with autocontrol valve 4 by oil inlet pipe 3 respectively.The three-way pipe 6 that autocontrol valve 4 is communicated with oil outlet tube 5 by forward and backward oil inlet pipe 3, built-in rotatable spool 7 in the three-way pipe 6, running shaft 11 in the middle of the pendulum mass of spool 7, support 9 by valve body 6 and the hinge joint of valve body 6 two ends, form with the counterweight swing ball 10 that support 9 is affixed, and spool 7 is by rotatable pendulum mass 11, form with the pendulum 12 that pendulum mass 11 upper ends are affixed, running shaft 11 is positioned at three-way pipe 6 lower ends in the middle of the pendulum mass, oil outlet tube 5 is communicated with oil outlet 8 by oil pump 13, and valve body 6 is rigidly connected with engine body.
The working procedure of this engine lube system is as follows: during engine operation, oil pump 13 is driven, and machine oil the past oil-feed filter core 2, back oil-feed filter core 21 respectively enters autocontrol valve 4 along oil inlet pipe 3, and the pendulum mass 11 in the spool 7 can freely swing.Oil-feed situation in the time of can changing static state by the connection angle that changes pendulum 12 and 11 times counterweight swing balls 10 of pendulum mass; What height by changing pendulum 12 and valve body 6 intermediate width realized a certain inflow pipeline 3 closes the inclined height limit.Valve body 6 oil outlet tubes 5 are communicated with oil pump 13 filler openings 3, preceding oil inlet pipe 3 from oil groove 1 front end through preceding oil inlet pipe filter core 2 oil suctions, back oil inlet pipe 31 from oil groove 1 rear end through after 21 oil-feeds of oil inlet pipe filter core.When motor goes up a slope, oil flows to oil groove 1 rear portion under the deadweight effect, this is that pendulum mass 11 in the autocontrol valve 4 still keeps under the 10 deadweight effects of counterweight swing ball vertical, valve body 6 then tilts with fuselage, the cross section that pendulum 12 has reduced the front end oil-feed mouth of pipe 3 on the pendulum mass 11 like this, oil inlet pipe mouth 3 is shut fully before after the inclination angle reaches several angle, guarantee that front end air can not enter, and can only suck machine oil from back oil inlet pipe mouth 31, vice versa, when descending, under the deadweight effect, machine oil flows to oil groove 1 front end, and at this moment valve body 6 also is tilted to preceding and pendulum mass 11 is subjected to the 10 deadweight effects of counterweight swing ball still to be in plumbness, so just reduces and even closes back oil inlet pipe mouth 31, guarantee that back oil inlet pipe mouth 31 air can't enter, thereby fully from front end inhalation machine oil, the machine oil that enters main oil gallery is given each main bearing and protruding shaft bearing through a minute oil duct, and four inclined hole branches on bent axle are given four rod journals again then.Also there is special oilhole to communicate between the connecting rod CONCENTRIC REDUCER, connecting rod small end is lubricated.Another part machine oil upwards feeds in the valve rocker hollow shaft along upright opening, lubricated rocker arm bush, and the boring from the rocking arm is flowed out then, is dropped on other part time job surface of distribution device.Owing to run up, the machine oil that releases from main bearing and connecting rod bearing etc. is spilt into tiny oil droplet, and surfaces such as casing wall, cam and tappet are lubricated.Some machine oil leads to oil pump along main oil pipe in addition, lubricated its working surface.The machine oil of all friction surfaces of flowing through all flows back to oil groove at last, and therefore, the proper functioning of lubricating system shows as machine oil and do continual circulation with the pressure and temperature of regulation in whole oil-way system.Owing on oil inlet pipe 3, increased an autocontrol valve 4, and with oil inlet pipe by original one change into before and after each one 3,31, can guarantee effectively that the lubricant oil fuel feeding is lubricated under the state of slope, thereby prolonged motor working life, be particularly suitable in climbing class machineries such as bulldozer, rake storehouse machine and tank, using.
The utility model has the following advantages compared to existing technology:
1, simple in structure, easy to manufacture, cost is low.
2, the lube system fuel feeding is abundant under the state of engine slope, and the lubricating efficiency height can be greatly Prolong the service life of engine.
