Detailed description of the invention
Double clutch coolant rate control valve, comprises valve body 2, side valve type spool 3, resetting-mechanism 8 and pressure-control valve 1. In valve body 2, establish cavity. Side valve type spool 3 is placed in cavity, can in cavity, smoothly move. Side valve type spool 3 arranges continuously successively and coordinates the work of suit to push valve platform 31, the first control valve platform 32, the second control valve platform 33 and reset valve platform 34 with cavity.
Cavity one end pushes valve platform 31 with work and in cavity, forms propelling movement oil pocket, pushes oil pocket and is communicated with pressure-control valve 1;
The cavity other end is arranged resetting-mechanism 8 and is inserted in and props up reset valve platform 34; Resetting-mechanism 8 can be a back-moving spring.
Cavity upper side wall is opened first clutch cooling vent 6, second clutch cooling vent 7 successively; Cavity lower wall is opened the first oil-in 4, the second oil-in 5 successively.
The first control valve platform 32 pushes valve platform 31 with work and cavity section between the two forms the first control oil pocket. The second control valve platform 33 and the first control valve platform 32 and cavity section between the two form second and control oil pocket.
The second control valve platform 33 has radially sulculus 35 towards the sidewall surfaces of the first control valve platform 32, and described radially sulculus 35 and second is controlled oil pocket and is engaged in and on axial section, is stairstepping oil recess structure. This radially sulculus 35 can process from the direct borehole of the second control valve platform 33 sidewall surfaces, can increase the fluid flow area of the second control oil pocket.
The second control valve platform 33 forms draining chamber with reset valve platform 34 and cavity section between the two. Draining chamber lower wall arranges draining hole 9. Off working state, work pushes valve platform 31 and props up the cavity that pushes oil pocket side, and draining chamber is communicated with second clutch cooling vent 7, draining hole 9 simultaneously.
When speed changer work, when the cooling oil flow of double clutch demand is monitored and calculated to control system of speed variator, the current signal of gearbox controlled pressure control valve 1, the pressure that cooling oil is entered to propelling movement oil pocket carries out proportion control, and in pressure change procedure, the cooling flow control mode of clutch is as follows:
Off working state, pressure-control valve 1 is to pushing oil pocket input cooling pressure, resetting-mechanism 8 propelling movement work push valve platform 31 and prop up the cavity that pushes oil pocket side, and the first control valve platform 32 is blocked first clutch cooling vent 6, and only the first oil-in 4 and the first control oil pocket are communicated with. The second control valve platform 33 present positions are not all communicated with the second control oil pocket with the second oil-in 5 and second clutch cooling vent 7, in double clutch, cooling oil flow is closed. Now, draining chamber is communicated with second clutch cooling vent 7, draining hole 9 simultaneously, can carry out cooling oil draining to double clutch coolant rate control valve, fluid will be discharged through second clutch cooling vent 7, the second control oil pocket, draining hole 9 by double clutch sheet.
The low discharge control stage, pressure-control valve 1 is controlled cooling oil pressure and is increased gradually, work pushes valve platform 31 fluid that is cooled and pushes resetting-mechanism 8 to, drive the first control valve platform 32 to slide into after certain distance, first control oil pocket start to be communicated with gradually with first clutch cooling vent 6 until completely connection, cooling oil enters the first control oil pocket by the first oil-in 4 and is exported to double clutch by first clutch cooling vent 6. Now, the second control valve platform 33 is also driven slip, and the second oil-in 5 is communicated with the second control oil pocket gradually, and second clutch cooling vent 7 and second is controlled oil pocket and still kept not being communicated with. This stage is the low discharge control stage, and cooling oil is exported to double clutch by first clutch cooling vent 6, and pressure increases gradually.
The high flow capacity high accuracy control stage, pressure-control valve 1 is controlled cooling oil pressure and is continued to increase, work pushes valve platform 31 fluid that is cooled and continues to push to resetting-mechanism 8, the first oil-in 4, first clutch cooling vent 6 continue to keep to be communicated with completely with the first control oil pocket, the second control valve platform 33 is driven to resetting-mechanism 8 and continues to slide, the second oil-in 5 and the second control oil pocket complete and are communicated with, and radially sulculus 35 and the second control oil pocket coordinate the stairstepping oil recess structure presenting to be progressively communicated with second clutch cooling vent 7.
Cooling oil pressure constantly increases, until that resetting-mechanism 8 can not continue is compressed, now, after the first oil-in 4 is communicated with first clutch cooling vent 6 completely by the first control oil pocket, the long-pending maximum that reaches of logical pasta that the second oil-in 5 is communicated with second clutch cooling vent 7 by the second control oil pocket, clutch cooling oil reaches maximum stream flow.
In the time of the larger cooling oil of demand, too much cooling oil can produce certain towing moment of torsion in clutch disc flow process, therefore, stairstepping oil recess structure progressively can strictly be controlled cooling oil flow accuracy with second clutch cooling vent 7 handshaking procedures, avoids pulling moment of torsion.
