201610437208.9 the flow control valve of entitled " a kind of double clutch gearbox lubricating system volume control device ", though
It so can be carried out active lubrication, however the opening and closing of its mainstream metering-orifice is to adjust by the relative motion cooperation of spool and piston to realize
Whole, requirement on machining accuracy is very high at the cooperation of spool and piston, also to do a large amount of detection work to the element precision of processing,
Cause overall cost high, the switch of mainstream metering-orifice is cooperatively formed by the chamfering sealing between spool and piston, is such as processed
Existing deviation, will lead to control valve can not be successfully closing, and in long-time use process, chamfering mating surface is easy percussion grinder
Damage leads to stuck piston spool and control is failed.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of speed changing box lubricating system flow control valve, structure are simply tight
It gathers, cancels valve core structure, the opening and closing of working connection oil groove are individually controlled by piston, the requirement on machining accuracy of part is significantly
It reduces, reduces the risk of cost and the failure of product working motion.
The technical scheme is that a kind of speed changing box lubricating system flow control valve, including it is provided centrally with oilhole channel
And outer housing and end cap that the two is together by a threaded connection, the outer housing and end cap junction are provided with O-ring seal,
Spring base and valve pocket are provided at step surface at oilhole channel in the end cap, the valve pocket outer surface is axially disposed
There is the working connection oil groove of perforation front and rear surfaces, piston that can be free to slide along valve pocket inner surface is provided in the valve pocket, it is described
Spring is installed, the piston tail end is provided with spring mounting hole, is provided on the piston through front and rear surfaces on spring base
Bypass oil hole, the spring at front end is located in spring mounting hole, the oilhole through front and rear surfaces is provided on the spring base,
The piston moves rearwards to the oil circuit behind position between isolation sealing working connection oil groove and oilhole in compressed spring under oil pressure effect
Channel.
Preferably, the front and back end end point at working connection oil groove is located on the valve pocket to be machined with along axial perforation valve pocket
The through-hole of inner surface, no oil pressure state lower piston are located at the position between the through-hole of front and back end two.
Preferably, the oilhole at least two on the spring base, and be uniformly distributed along its circumferencial direction.
The configuration of the present invention is simple novelty is compact, safe and reliable, high lubricating effect, simplifies mainstream metering-orifice design side
Case cancels valve core structure, and the opening and closing of mainstream metering-orifice are individually controlled by piston, and piston moves downward to bottom and closes mainstream
Metering-orifice, part processing precision substantially reduce, and reduce the risk of cost and product failure.

Specific embodiment
With reference to the accompanying drawing, invention is further described in detail.
As shown in Figures 1 to 4, the present invention provides a kind of speed changing box lubricating system flow control valves, including center to be arranged
There is oilhole channel and outer housing 1 and end cap 2 that the two is together by a threaded connection, the outer housing 1 and 2 junction of end cap are set
Be equipped with O-ring seal 3, at the oilhole channel in the end cap 2 in step surface at be provided with spring base 4 and valve pocket 5, the valve
Cover the axially disposed working connection oil groove 6 for having perforation front and rear surfaces in 5 outer surfaces, be provided in the valve pocket 5 can along valve pocket 5 table
Face piston 7 free to slide is located at the front and back end end point at working connection oil groove 6 on the valve pocket 5 and is machined with and passing through along axial
Port valve covers the through-hole 12 of 5 inner surfaces, and no oil pressure state lower piston 7 is located at the position between the through-hole 12 of front and back end two, described
Spring 8 is installed, 7 tail end of piston is provided with spring mounting hole 9, is provided on the piston 7 through front and back on spring base 4
The bypass oil hole 10 on surface, 8 front end of spring are located in spring mounting hole 9, are provided on the spring base 4 through front and back table
The oilhole 11 in face, the oilhole 11 at least two on the spring base 4, and be uniformly distributed along its circumferencial direction, the piston 7 exists
Oil pressure, which acts on after lower compressed spring 8 moves rearwards to position, completely cuts off the asphalt channel between sealing working connection oil groove 6 and oilhole 11.
Under normal circumstances, the flow control valve of the application is in the open state, can play towards wheel lubricating oil in gear-box good
The function of good lubrication and cooling, as shown in figure 3, lubricating oil enters to the right side of piston 7 out of 1 side of outer housing oilhole channel
Side, most lubricating oil is via the left side for entering to piston 7 after the through-hole 12 and working connection oil groove 6 of valve pocket 5, then via oilhole
It is flowed out from the oilhole channel of 2 side of end cap after 11, least a portion of lubricating oil passes through piston 7 directly from bypass oil hole 10, right
Part in gear-box is lubricated.When gearbox work is frequently or under limiting condition, to guarantee inner gear of the gear box
Normal lubrication and cooling, as shown in figure 4, lubricating oil enters from right end, powerful oil pressure pushes piston 7 to move downward to the leftmost side
At step, piston 7 closes the through-hole 12 in 5 left side of valve pocket, has separated the asphalt channel between working connection oil groove 6 and oilhole 11, has made
Piston 7 can only be passed through from bypass oil hole 10 by obtaining lubricating oil, so that being maintained at a small amount of state profit into the lubricating oil in gear-box
It is sliding, so that gearbox is in shift hunting or limiting condition lower gear is in effectively lubricating and the state of cooling.
The above is only better embodiment of the invention, not makes any form of restriction to invention, it is all according to
According to technical principle any simple modification, equivalent variations or modification made to the above embodiment of the invention, the present invention is still fallen within
In the range of technical solution.
