Technical field
The present invention relates to a kind of valve bodies, more particularly, to a kind of speed changing box lubricating system flow control valve.
Background technique
Before domestic automobile gearbox mostly use traditional crankshaft splashing lubricating system greatly guarantee gear lubrication and
Cooling in gearbox.With the development of technology, slowly someone designs gearbox active lubrication by the way of active lubrication
System, active lubrication is high-efficient, and lubricating system is unaffected under the variation of temperature.Someone devise one application No. is
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 novelty, 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 big
Amplitude reduction 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 internally provided 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,
It is provided with piston mounting holes in the end cap, piston is installed in the piston mounting holes, the piston base is provided with spring
Mounting hole is provided with spring in the spring mounting hole, and the spring other end is located in end cap at the step in oilhole channel,
The bypass oil hole of perforation front and rear surfaces is provided on the piston, the wall outer surface of the piston is provided with before and after connection piston
The working connection oil groove on surface, the piston support after oil pressure effect compressed spring moves rearwards to position in piston mounting holes bottom
Step at isolation sealing working connection oil groove.
Preferably, the piston end surface offers lateral oil groove, and the transverse direction oil groove is connected with working connection oil groove.
Preferably, the bypass oil hole is provided on lateral oil groove.
Preferably, the working connection oil groove and lateral oil groove are rectangular channel.
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, which retreats under oil pressure effect to bottom, is
Mainstream metering-orifice can be closed, and itself number of parts is few, requirement on machining accuracy also decreases, while assembling also simple, reduction
The risk of cost and product failure.

Specific embodiment
With reference to the accompanying drawing, the present invention is described in further details.
As shown in Figures 1 to 4, the present invention provides a kind of speed changing box lubricating system flow control valves, including internal setting
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
It is equipped with O-ring seal 3, piston mounting holes 4 are provided in the end cap 2, piston 5 is installed in the piston mounting holes 4, it is described
5 bottom of piston is provided with spring mounting hole 6, and spring 7 is provided in the spring mounting hole 6, and 7 other end of spring is located in
In end cap 2 at the step in oilhole channel, the bypass oil hole 8 of perforation front and rear surfaces is provided on the piston 5, the piston 5
Wall outer surface be provided with connection 5 front and rear surfaces of piston working connection oil groove 9, the piston 5 oil pressure act on compressed spring 7 to
It moves afterwards and supports the isolation sealing working connection oil groove 9 at the step of 4 bottom of piston mounting holes afterwards in place.
As a preferred scheme, 5 end face of piston offers lateral oil groove 10, the transverse direction oil groove 10 and main oil
Road binders slot 9 is connected, and the bypass oil hole 8 is provided on lateral oil groove 10, and the working connection oil groove 9 and lateral oil groove 10 are
Rectangular channel, the quantity of shown working connection oil groove 9 are two, are located on the opposite excircle side wall of piston 5, and respectively with cross
It is connected to the both ends of oil groove 10.
Under normal circumstances, the flow control valve of the application is in the open state, can play towards the lubricating oil in gear-box
Good lubrication and cooling function, as shown in figure 3, lubricating oil enters the right side of piston 5 out of 1 side of outer housing oilhole channel
Side, most of lubricating oil is via the left side for entering piston 5 after lateral oil groove 10 and working connection oil groove 9, then through the oilhole in end cap 2
Channel outflow, small part lubricating oil pass through piston 5 directly from bypass oil hole 8, are lubricated to the part in gear-box.Work as change
The work of fast case is frequently or under limiting condition, for the normal lubrication and cooling for guaranteeing inner gear of the gear box, as shown in figure 4,
Lubricating oil enters from right end, and powerful oil pressure pushes piston 7 to move downward to the step of 4 bottom of left hand piston mounting hole, living
The working connection oil groove 9 for filling in 5 outer walls is blocked, and lubricating oil can only pass through piston 5 from bypass oil hole 8, so that into gear-box
In lubricating oil be maintained at a small amount of state lubrication so that gear is still located when gearbox is under shift hunting or limiting condition
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.
