Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention.
Detailed description of the invention
The embodiment of passenger vehicle of the present invention: as shown in Figure 1, this passenger vehicle comprises power-transfer clutch and rides 3 and have the clutch control of limping function, described clutch control comprises the clutch cylinder 5 for driving the clutch of passenger vehicle to carry out the clutch action of being correlated with, for inflating the gas bag 1 slided with the piston of driving clutch cylinder 5 to clutch cylinder 5, wherein clutch cylinder 5 has for being communicated with to promote the disengagement chamber 5-1 of the disengaging of clutch of passenger vehicle and the binding cavity 5-2 for being communicated with to make the power-transfer clutch of passenger vehicle to be combined with gas bag 1 with gas bag 1, disengagement chamber electromagnetic valve 8 is provided with between the disengagement chamber 5-1 and gas bag 1 of clutch cylinder 5, binding cavity electromagnetic valve 6 is provided with between the binding cavity 5-2 and gas bag 1 of clutch cylinder 5, disengagement chamber electromagnetic valve 8 is normal open electromagnetic valve, binding cavity electromagnetic valve 6 is normally closed solenoid valve, and be communicated with gas bag 1 by three-way pipe 7 after the crossing for the import be communicated with gas bag 1 of disengagement chamber electromagnetic valve 8 and binding cavity electromagnetic valve 6, on disengagement chamber electromagnetic valve 8 and binding cavity electromagnetic valve 6, control linkage has the controller (not shown) for making disengagement chamber electromagnetic valve 8 and binding cavity electromagnetic valve 6 all be in closed condition, the disengagement chamber 5-1 of clutch cylinder 5 is communicated with by the double-way check valve 4 arranged between the two with disengagement chamber electromagnetic valve 8, this double-way check valve 4 has two imports 11 mutually cut off, 12 and one can with two imports 11, one in 12 outlet 20 be communicated with, wherein the outlet of double-way check valve 4 is communicated with the disengagement chamber 5-1 of clutch cylinder 5, two imports 11, 12 are communicated with two-position three-way valve 2 with disengagement chamber electromagnetic valve 8 respectively, described two-position three-way valve 2 has and the outlet of the inlet communication of double-way check valve 4 and two imports for being communicated with gas bag 1 with air respectively mutually cut off, and make one of them unlatching of two imports for controlling two-position three-way valve 2 of two-position three-way valve 2, another valve rod of closing and pedal of clutch 3 are in transmission connection.
In use, after factory's pattern is returned in the chaufeur limping of opening on passenger vehicle, controller controls disengagement chamber electromagnetic valve 8 and binding cavity electromagnetic valve 6 is all in normally off in the present invention; Then chaufeur push down on the pedal, controlling two-position three-way valve 2 makes the gas in gas bag 1 flow into double-way check valve 4 gradually, because double-way check valve 4 import 12 air pressure is larger than import 11 air pressure, so gas leads to outlet 20 from import 12, enter the disengagement chamber 5-1 of separation cylinder and promote piston, the gas of the piston other end (in binding cavity 5-2) leads to air by the exhausr port of binding cavity electromagnetic valve 6 discharges, and realizes the separation of power-transfer clutch; Then chaufeur is after start the engine, slow releasing pedal of clutch 3, two-position three-way valve 2 import is made to lead to air, now the outlet air pressure of double-way check valve 4 is large, import 12 is communicated with again with outlet 20, therefore under the combined action of diaphragm spring and push rod spring, the gas in the disengagement chamber 5-1 of now clutch slave cylinder flows to two-position three-way valve 2 by the import 12 of double-way check valve 4, finally discharges in air.The piston of clutch cylinder 5 pushes back gradually in addition, and air covers in the binding cavity 5-2 of clutch cylinder 5 by the exhausr port of binding cavity electromagnetic valve 6 gradually, realizes the slow combination of power-transfer clutch thus.
In the present invention, pedal of clutch coordinates with gas circuit and can ensure being combined slowly of power-transfer clutch.When car load motor breaks down, now those control system, comprise electromagnetic valve and so on, may lose efficacy, also may still can normally work, and when electromagnetic valve can normally work, also likely by realizing the opening and closing of power-transfer clutch to the break-make gas of cylinder.But there is a problem here, the combination of usual power-transfer clutch, the speed discrepancy of two ends part (referring to driving engine and motor) is very little, generally only has the difference of 50 turns, and at this time the combination of control clutch is automatically controlled, and binding time is no more than 1s.But when after electrical fault, after the startup of driving engine, minimum speed (idling usually said) is at about 700rpm, and now this end of motor is 0 turn, if be still automatically controlled combination in 1s, then very large to the impact of part, driving engine is suppressed flame-out.So I thinks in the patent add pedal of clutch, air valve, double-way check valve etc., the slow combination (generally at 2-3s) of power-transfer clutch instead of automatically controlled can be realized like this by the slow relieving pedal of chaufeur, can avoid impacting greatly, driving engine is suppressed flame-out problem.
The embodiment with the clutch control of limping function of the present invention: as shown in Figure 1, in the above-described embodiments, describes in detail about the clutch control with limping function, therefore repeats no more in the present embodiment.
