Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
Consult shown in Fig. 1-3, converter coupling control valve of the present invention, this control valve and a main oil circuit 1 that supplies, gear clutch control valve 10 is connected with lock-up clutch 11, this control valve comprises locking spool 2 and flow spool 3, main for oil circuit 1 respectively with one end of locking spool 2 and flow spool 3, gear clutch control valve 10 is connected, the main oil circuit 1 that supplies is connected with the other end of flow spool 3 with first throttle valve 5 through one-way valve 4, and also comprise the oil circuit control 7 with pitot pressure induction installation 6, oil circuit control 7 is connected with the end of locking spool 2, and on locking spool 2, be arranged with spring 8, in the time that the oil pressure of oil circuit control 7 is greater than the elastic force of spring 8, locking spool 2 moves to left, and the main oil circuit 1 that supplies is connected with flow spool 3, and control fuel feeding or the draining of lock-up clutch 11 through flow spool 3.Wherein, main for being also provided with the second throttle valve 17 between oil circuit 1 and gear clutch control valve 10, its throttling action can need to set according to use.And be also provided with the 3rd throttle valve 16 between pitot pressure induction installation 6 and the end of locking spool 2, for stablizing the oil pressure of pitot pressure induction installation induction.In the present invention, by the parallel connection of one-way valve, first throttle valve (4,5), the quick draining of right-hand member cavity volume and the throttling that realize flow spool 3 are oil-filled, have realized the object of the quick draining of lockup clutch.
Between locking spool 2 and spring 8, be provided with multiple adjustment pads 9, adjust pad 9 for regulating locking rotating speed.In the present invention, the oil pressure that pitot pressure induction installation 6 offers oil circuit control 7 is corresponding with turbine output speed (locking rotating speed), and controlling the movement of locking spool 2, adjust the quantity of pad 9 by increase and decrease, the oil pressure of the oil circuit control 7 that control locking spool 2 moves can change, and then changes locking rotating speed.
Locking spool 2 comprises two 15 of 14 of spool and spools, and the diameter that spool is 14 is greater than the diameter of two 15 of spools, for locking rotating speed higher than release rotating speed.When locking spool 2 is moved to the left, lockup clutch is in supplying oil condition, can increase an active force, the power acting in conjunction producing with the oil circuit control 7 of pitot pressure induction installation 6 promotes locking spool 2 return springs 8, because the oil pressure of oil circuit control 7 is corresponding with lock-up clutch 11 locking rotating speeds, lock-up clutch 11 locking rotating speeds and release rotating speed are just different, have avoided ceaselessly locking and release of lockup clutch 11 under a certain critical locking rotating speed.
Flow spool 3 comprises the first spool body 12 and the second spool body 13, the diameter of the first spool body 12 is less than the diameter of the second spool body 13, in the time of lock-up clutch locking, by flow spool differential action, compulsive unlocking during for gear shift, locking again after shift end.In the present invention, flow spool 3 is also being controlled fuel feeding and the draining of lockup clutch 11, under normal circumstances, after the gear stable operation that gear clutch control valve 10 is controlled, this part is less by oil mass, there is hardly pressure difference in the second throttle valve 17 front and back, flow spool 3 left and right pressure at two ends are almost identical, due to the differential action of spool, flow spool 3 is in left position, in the time of 10 gear shift of gear clutch control valve, the second throttle valve 17 two ends produce larger pressure difference and reach certain value, flow spool 3 right-hand member power are greater than the power of left end, can promote flow spool 3 moves right.After stable operation, flow spool 3 can return to left position.One-way valve, first throttle valve (4,5) realize the flow spool quick draining of 3 right-hand member cavity volume and throttling oil-filled.Realize the function of gear shift release, realized lockup clutch 11 release speed faster than the speed of locking again simultaneously.
Above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
