Description of drawings
Fig. 1 is the structural representation of embodiments of the invention.
The specific embodiment
The embodiment of passenger vehicle of the present invention: as shown in Figure 1; This passenger vehicle comprises power-transfer clutch foot-operated 3 and the clutch control with limping function; Said clutch control comprise the clutch action that the clutch that is used to drive passenger vehicle is correlated with clutch cylinder 5, be used for gas bag 1 from the piston that drives clutch cylinder 5 to clutch cylinder 5 inflations that slide with; Wherein clutch cylinder 5 has and is used for being communicated with gas bag 1 with the disengagement chamber 5-1 of the disengaging of clutch that promotes passenger vehicle and is used for being communicated with so that the binding cavity 5-2 of the power-transfer clutch combination of passenger vehicle with gas bag 1; Between the disengagement chamber 5-1 of clutch cylinder 5 and gas bag 1, be provided with disengagement chamber electromagnetic valve 8; Between the binding cavity 5-2 of clutch cylinder 5 and gas bag 1, be provided with binding cavity electromagnetic valve 6; Disengagement chamber electromagnetic valve 8 is the normal open electromagnetic valve; Binding cavity electromagnetic valve 6 is a normally closed solenoid valve, and the import that is used for being communicated with gas bag 1 of disengagement chamber electromagnetic valve 8 and binding cavity electromagnetic valve 6 back that crosses is communicated with gas bag 1 through three-way pipe 7, and control linkage is useful on the controller (not shown) that makes disengagement chamber electromagnetic valve 8 and binding cavity electromagnetic valve 6 all be in closed condition on disengagement chamber electromagnetic valve 8 and the binding cavity electromagnetic valve 6; The disengagement chamber 5-1 of clutch cylinder 5 and disengagement chamber electromagnetic valve 8 are communicated with through the bilateral check valve 4 that is provided with between the two; This bilateral check valve 4 have 11,12 and one of two imports that each other cut off can with an outlet that is communicated with 20 in two imports 11,12; Wherein the outlet of bilateral check valve 4 is communicated with the disengagement chamber 5-1 of clutch cylinder 5; Two imports 11,12 are communicated with disengagement chamber electromagnetic valve 8 and two-position three-way valve 2 respectively; Said two-position three-way valve 2 has that the outlet that is communicated with the import of bilateral check valve 4 and two cut off each other is used for the import that is communicated with atmosphere and gas bag 1 respectively, and one of them unlatching, another valve rod of closing and the pedal of clutch 3 of two imports that is used to control two-position three-way valve 2 of two-position three-way valve 2 is in transmission connection.
The present invention in use, chaufeur is opened after limping on the passenger vehicle returns factory's pattern, controller control disengagement chamber electromagnetic valve 8 all is in normally off with binding cavity electromagnetic valve 6; Chaufeur push down on the pedal then; Control two-position three-way valve 2 makes the gas in the gas bag 1 flow into bilateral check valve 4 gradually; Because bilateral check valve 4 imports 12 air pressure are bigger than import 11 air pressure,, get into the disengagement chamber 5-1 of separation cylinder and promote piston so gas leads to outlet 20 from import 12; The gas of the piston other end (in the binding cavity 5-2) leads to the atmosphere discharge through the exhausr port of binding cavity electromagnetic valve 6, realizes the separation of power-transfer clutch; Then chaufeur is behind start the engine; Slowly release the clutch pedal 3 makes two-position three-way valve 2 imports lead to atmosphere, and the outlet air pressure of bilateral check valve 4 is big at this moment; 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 clutch slave cylinder flows to two-position three-way valve 2 through the import 12 of bilateral check valve 4 at this moment, finally discharges in the atmosphere.The piston of clutch cylinder 5 pushes back gradually in addition, and atmosphere covers among the binding cavity 5-2 of clutch cylinder 5 through the exhausr port of binding cavity electromagnetic valve 6 gradually, realizes the slow combination of power-transfer clutch thus.
Pedal of clutch can guarantee combining slowly of power-transfer clutch with the gas circuit cooperation among the present invention.When the car load motor broke down, this moment, those control system comprised electromagnetic valve and so on; Possibly lose efficacy; Also maybe be still can normal operation, and when electromagnetic valve can normal operation, also might be through the break-make gas of cylinder being realized the opening and closing of power-transfer clutch.But there is a problem here, the combination of power-transfer clutch usually, the speed discrepancy of two ends part (referring to driving engine and motor) is very little, generally has only the difference of 50 commentaries on classics, and at this time the combination of control clutch is automatically controlled, and binding time is no more than 1s.But after electrical fault, minimum speed after the startup of driving engine (idling of saying usually) is about 700rpm, and this moment, this end of motor was 0 commentaries on classics, if be still automatically controlled combination in 1s, then the impact to part is very big, suppresses driving engine flame-out.So thinking, I have added pedal of clutch, air valve, bilateral check valve etc. in patent; Can realize the slow combination (generally at 2-3s) of power-transfer clutch rather than automatically controlled through the slow relieving pedal of chaufeur like this; Can avoid impacting greatly, suppress flame-out problem to driving engine.
Embodiment with clutch control of limping function of the present invention: as shown in Figure 1, in the above-described embodiments, specify about clutch control with limping function, therefore repeat no more in the present embodiment.
