Specific embodiment
As illustrated, a kind of wet clutch with voltage stabilizing function, including main shaft 1, clutch plunger cylinder 2, clutch
Hub 5, friction plate 6, antithesis piece 7 and spring assembly 8, main shaft 1 and clutch plunger cylinder 2 in the outer hub 4 of piston 3, clutch, clutch
Cylinder interference fit, the outer hub 4 of clutch passes through spline connection with friction plate 6, and friction plate 6 is paper-base friction wafer 6.Antithesis piece 7 with
In clutch, hub 5 passes through spline connection.Hydraulic oil inlet 101 is provided with main shaft 1, main shaft 1 and clutch plunger cylinder 2 are all built-in
There is oil duct.Described clutch plunger cylinder 2 has a valve opening 9, has between this valve opening 9 and plunger shaft of clutch plunger cylinder 2
There are an oil-in 10 and a feedback hydraulic fluid port 11, wet clutch also includes LD valve stable-pressure device, and LD valve stable-pressure device is main
By LD valve piston cylinder 12, active piston 13, formed by piston 14 and LD valve spring 15, LD valve piston cylinder 12 is arranged on clutch
In the valve opening 9 of piston cylinder 2, and between the outer wall of LD valve piston cylinder 12 and the inwall of valve opening 9, it is formed with oil pocket I 16, described active
The piston rod of piston 13 is arranged in LD valve piston cylinder 12, and the external part of piston rod connects piston, is arranged on master by piston 14
In cavity between piston 13 and clutch plunger cylinder 2, and by the diameter of the valve opening at piston 14 than active piston 13 at
Valve opening diameter little, the sectional area of therefore active piston 13 is than by the big 2%-10% of piston 14 sectional area.Remote by piston 14
It is provided with stopper 17 from active piston 13 one end, between stopper 17 and valve opening 9, be formed with oil pocket II 18, active piston 13 and passively living
Plug 14 is connected with each other by LD valve spring 15, and the hydraulic oil inlet 101 of main shaft 1 is communicated to oil pocket I 16, oil pocket II 18 by oil duct
Pass through feedback hydraulic fluid port 11 to connect and the plunger shaft of clutch plunger cylinder 2 between.
Described clutch is entered in the oil duct of main shaft 1 by hydraulic oil inlet 101, and from the oil duct of main shaft 1 through from
The oil duct of clutch piston cylinder 15, reaches the oil duct of clutch plunger cylinder 2, eventually arrives in oil pocket I 16.Because oil pressure is by LD valve master
Piston 13 down promotes so that clutch oil-in 10 is connected with oil pocket I 16, and fluid enters into clutch plunger cylinder 2
In plunger shaft, and formed pressure promote clutch plunger 3 move to friction plate 6 direction, clutch plunger 3 is in the effect of oil pressure
Under overcome spring force produced by spring assembly 8, friction plate 6 and antithesis piece 7 are pressed together the most at last；Due to friction plate 6 with
The outer hub 3 of clutch is spline connection, and antithesis piece 7 is also spline connection with hub 4 in clutch.The power of so main shaft 1 just leads to
Cross the frictional force between friction plate 6 and antithesis piece 7 and pass to the outer hub 3 of clutch, thus reach clutch combining.In clutch knot
After being opened due to clutch oil-in 10 during conjunction, fluid not only enters in the plunger shaft of clutch plunger cylinder 2, with
When by feed back hydraulic fluid port 11 enter in oil pocket II 18, thus promote LD valve move upwards by piston 14 so that LD valve active
Piston 13 moves in the presence of LD valve is by piston 14 upwards, and clutch enters oil-in 10 and is just gradually reduced, but due to LD valve
The oil pressure lifting surface area of active piston 13 than LD valve by the big 2%-10% of the oil pressure lifting surface area of piston 14 so that LD valve is actively lived
The hydraulic coupling of plug 13 is more than LD valve by the pressure of piston 14 so that LD valve active piston 13 and LD valve are finally tieed up by piston 14
Hold in the state of a balance, ensure that oil-in 10 is always on simultaneously.Produce when being supplied to the pressure into hydraulic oil inlet 101
Changing or the centrifugal force of the high-speed rotation generation due to axle, can cause the pressure of clutch inside cavity to produce and become
Change, fluctuation occurs；Due to increased LD valve, its balanced action can keep the pressure of clutch inside cavity to maintain all the time
One stable state, thus ensureing the stability that clutch combines, improves the service life of clutch.When hydraulic oil inlet 101
When no fluid is entered, clutch is in disengaged condition, now has gap between friction plate 6 and antithesis piece 7, due to the height of axle
The centrifugal force that speed rotation produces can make antithesis piece 7 produce long-term vibration middle.Because antithesis piece of the present invention is
Positive heptagon antithesis piece, and seven angles of antithesis piece are fillet.The antithesis piece of this kind of shape produces in the case of vibrations
The frequency of the wave time and vibration frequency antithesis piece than conventional circle reduces 80%-90%, substantially reduces antithesis piece
Vibration number, reduces the abrasion of friction plate, improves the service life of clutch.
