Embodiment
As shown in the figure, a kind of wet clutch with voltage stabilizing function, comprise hub 5, friction plate 6, antithesis sheet 7 and spring assembly 8 in main shaft 1, clutch plunger cylinder 2, clutch plunger 3, the outer hub 4 of clutch, clutch, main shaft 1 and clutch plunger cylinder 2 cylinder interference fit, the outer hub 4 of clutch is with friction plate 6 by spline joint, and friction plate 6 is paper-base friction wafer 6.Antithesis sheet 7 passes through spline joint with hub 5 in clutch.Main shaft 1 is provided with hydraulic oil inlet 101, main shaft 1 and clutch plunger cylinder 2 are all built-in with oil duct.Described clutch plunger cylinder 2 has a valve opening 9, there is between this valve opening 9 and piston cavity of clutch plunger cylinder 2 filler opening 10 and one feed back hydraulic fluid port 11, wet clutch also comprises LD valve stable-pressure device, LD valve stable-pressure device is primarily of LD valve piston cylinder 12, active piston 13, passive piston 14 and LD valve spring 15 form, LD valve piston cylinder 12 is arranged in the valve opening 9 of clutch plunger cylinder 2, and be formed with oil pocket I 16 between the outer wall of LD valve piston cylinder 12 and the inwall of valve opening 9, the piston rod of described active piston 13 is arranged in LD valve piston cylinder 12, the external part of piston rod connects piston, passive piston 14 is arranged in the cavity between active piston 13 and clutch plunger cylinder 2, and the diameter of the valve opening at passive piston 14 place is less than the diameter of the valve opening at active piston 13 place, therefore the large 2%-10% of the sectional area ratio of active piston 13 passive piston 14 sectional area.Passive piston 14 is provided with stopper 17 away from active piston 13 one end, oil pocket II 18 is formed between stopper 17 and valve opening 9, active piston 13 and passive piston 14 are interconnected by LD valve spring 15, the hydraulic oil inlet 101 of main shaft 1 is communicated to oil pocket I 16 by oil duct, is communicated with between the piston cavity of oil pocket II 18 and clutch plunger cylinder 2 by feedback hydraulic fluid port 11.
Described clutch enters into the oil duct of main shaft 1 by hydraulic oil inlet 101, and from oil duct through clutch plunger cylinder 15 of the oil duct of main shaft 1, arrives the oil duct of clutch plunger cylinder 2, finally arrives in oil pocket I 16.Because LD valve active piston 13 down promotes by oil pressure, clutch filler opening 10 is connected with oil pocket I 16, fluid enters into the piston cavity of clutch plunger cylinder 2, and mineralization pressure promotes clutch plunger 3 to move to friction plate 6 direction, clutch plunger 3 overcomes the spring force that spring assembly 8 produces under the effect of oil pressure, and friction plate 6 and antithesis sheet 7 are pressed together the most at last; Because the outer hub 3 of friction plate 6 and clutch is spline joints, and antithesis sheet 7 is also spline joint with hub 4 in clutch.The power of such main shaft 1 just passes to the outer hub 3 of clutch by the frictional force between friction plate 6 and antithesis sheet 7, thus reaches clutch combination.Due to after clutch filler opening 10 is opened in clutch cohesive process, fluid not only enters into the piston cavity of clutch plunger cylinder 2, enter into oil pocket II 18 by feedback hydraulic fluid port 11 simultaneously, thus the passive piston 14 of promotion LD valve moves upward, LD valve active piston 13 is moved upward under the effect of the passive piston 14 of LD valve, clutch enters filler opening 10 and just reduces gradually, but the 2%-10% larger than the oil pressure lifting surface area of the passive piston of LD valve 14 of the oil pressure lifting surface area due to LD valve active piston 13, the hydraulic coupling of LD valve active piston 13 is made to be greater than the pressure of the passive piston 14 of LD valve, under the state making LD valve active piston 13 and the passive piston 14 of LD valve finally maintain a balance, ensure that filler opening 10 is opened always simultaneously.The centrifugal force changing when the pressure feeding hydraulic oil inlet 101 or produce due to the High Rotation Speed of axle, can both cause the pressure of clutch inside cavity to change, and occurs fluctuation; Owing to adding LD valve, its balanced action can keep the pressure of clutch inside cavity to maintain a steady state all the time, thus ensures the stability that clutch combines, and improves the working life of clutch.When hydraulic oil inlet 101 is entered without fluid, clutch is in disengaged condition, now has gap between friction plate 6 and antithesis sheet 7, and the centrifugal force that the High Rotation Speed due to axle produces can make antithesis sheet 7 produce long-term vibration in centre.Because antithesis sheet of the present invention is positive Heptagon antithesis sheet, and seven of antithesis sheet angles are fillet.The wave time that the antithesis sheet of this kind of shape produces in the case of vibrations and vibration frequency reduce 80%-90% than the frequency of the antithesis sheet of conventional circle, substantially reduce the vibration number of antithesis sheet, reduce the wearing and tearing of friction plate, improve the working life of clutch.
