Abstract
The special manual unlocking pipeline for hydraulic speed changing includes one lock valve connected to the main oil path, lock clutch controlling oil path and oil pan and connected via the lock controlling oil path to the Pitot tube oil path; one throttling pin before the junction of the lock controlling oil path and the Pitot tube oil path; one Pitotmeter measuring point and one electromagnetic sliding valve connected to the oil pan following the throttling pin. The throttling pin has a throttling hole of 0.5-0.8 mm diameter, and the electromagnetic sliding valve is one two-position-two (or three) way valve. The present invention has sensitive and reliable acting, convenient control, possibility for automatic control and low cost.
Description
Technical field:
The present invention relates to a kind of torque converter, particularly relate to a kind of special-purpose artificial unlocking pipeline of torque converter.
Background technique:
Torque converter is widely used in engineering machinery field.For locking and the release that realizes the human intervention fluid torque converter, taked different modes both at home and abroad.Abroad, U.S. ALLISON company adopts one of new design can realize automatically controlled special-purpose lock valve, and the method realization by blocking skin holder oil pressure is to the artificial control of torque converter.Because adopted automatically controlled mode for the condition that provides is provided automatically, it is good to handle control performance, but cost is higher, uses wideless.At home, adopt the mode of letting out (falling) skin holder oil pressure, the general employing connects an oil pipe by skin holder pressure-measuring point, manually controls by a conventional stop valve.Because skin holder pressure-measuring point only be Z1/8 " the awl screw, the preceding oil pressure (skin holder oil pressure) of awl screw can not fall enough lowly, and is very insensitive, and can't reach functional requirement when skin holder oil pressure is high, its application is restricted.
Summary of the invention:
The technical problem to be solved in the present invention is: a kind of special-purpose artificial unlocking pipeline of torque converter is provided, to overcome the cost height that exists in the prior art, insensitive deficiency, realizes the locking and the release of human intervention fluid torque converter.
The present invention constitutes like this: it comprises lock valve (4), lock valve (4) is connected with working connection (3), lock-up clutch control oil channel (5), food tray (7), and be connected with skin holder oil circuit (1) by locking control oil channel (9), throttling pin (2) was arranged before the tie point of locking control oil channel (9) and skin holder oil circuit (1), skin holder pressure-measuring point (8), energising magnetic guiding valve (6) are arranged afterwards successively, and energising magnetic guiding valve (6) is connected with food tray (7).
The throttle diameter of throttling pin (2) is: φ 0.5-φ 0.8.
Energising magnetic guiding valve (6) adopts bi-bit bi-pass or two-position three way energising magnetic guiding valve.
The function of lock valve (4) is separation, the closure of control torque converter lock-up clutch, when reaching its control oil pressure (pressure requires different during different model), and lock valve (4) action, lock-up clutch engages or separates.
The present invention adopts the mode of letting out (falling) skin holder oil pressure, go up increase throttling pin (2) at locking control oil channel (9) control lock valve (4) skin holder oil circuit (1) before, take over the road by skin holder pressure-measuring point (8) again and enter pressure release return tray (7), and on this relief pipeline, add bi-bit bi-pass or two-position three way magnetic slide valve (6) carries out electrically controlled manipulation control.
Skin holder oil circuit (1) is controlled the action of lock valve (4) for locking control oil channel (9) by throttling pin (2) back.When energising magnetic guiding valve (6) no electric circuit, the oil pressure of locking control oil channel (9) is higher, lock valve (4) action, and lock-up clutch control oil channel (5) communicates the lock-up clutch closure with working connection (3).
The energising work of energising magnetic guiding valve (6), skin holder oil circuit (1) communicates with food tray (7) by throttling pin (2), energising magnetic guiding valve (6), because the throttling action of throttling pin (2), the fast prompt drop of oil pressure of locking control oil channel (9) gets very low, lock valve (4) return under spring action, lock-up clutch control oil channel (5) pressure release that communicates with food tray (7), lock-up clutch separates (release), promptly realizes fast artificial unlocking function.
Compared with prior art, the present invention is active in one's movements, reliably, and control is convenient, and for control automatically provide may, and cost is low.
Description of drawings:
Fig. 1 is the artificial dislock method hydraulic control schematic diagram of torque converter special use;
Fig. 2 is a throttling pin structure schematic representation.
Embodiment:
Embodiments of the invention: after making throttling pin 2 according to Fig. 2, connect according to shown in Figure 1, being about to lock valve 4 is connected with working connection 3, lock-up clutch control oil channel 5, food tray 7, and by locking control oil channel 9 just lock valve 4 be connected with skin holder oil circuit 1, before the tie point of locking control oil channel 9 and skin holder oil circuit 1, throttling pin 2 is set, set gradually skin holder pressure-measuring point 8, energising magnetic guiding valve 6 afterwards, energising magnetic guiding valve 6 is connected with food tray 7.
Wherein, energising magnetic guiding valve 6 adopts two two (three) magnetic slide valves all.
Claims (3)
1. the special-purpose artificial unlocking pipeline of a torque converter, it comprises lock valve (4), it is characterized in that: lock valve (4) is connected with working connection (3), lock-up clutch control oil channel (5), food tray (7), and be connected with skin holder oil circuit (1) by locking control oil channel (9), throttling pin (2) was arranged before the tie point of locking control oil channel (9) and skin holder oil circuit (1), skin holder pressure-measuring point (8), energising magnetic guiding valve (6) are arranged afterwards successively, and energising magnetic guiding valve (6) is connected with food tray (7).
