The left end of 20 inner cylinder face of axle sleeve is equipped with tapered opening 201 and, pressure corresponding with 101 position of pressure oilhole in main rotating hub 1
The right side hole edge and the small end 203 of tapered opening 201 that oilhole 101 exports match, and the right end of 20 inner cylinder face of axle sleeve is equipped with close
Sealing ring 19 is housed between the sealing surface 202 of cover 202, main rotating hub 1 and axle sleeve 20.
Embodiment：One specific practice of the utility model introduced below.
The utility model installs axle sleeve 20 in main rotating hub 1 and is equipped with tapered opening 201, and tapered opening 201 and master
The axial position of pressure oilhole 101 in rotating hub 1 is corresponding, realizes oil duct function.Axle sleeve 20 is equipped with sealing surface 202, and close
Seal 19 coordinates, and realizes the sealing to pressure oil cavity 6,16.
The outer ring body of main rotating hub 1 is equipped with equilibrium oil alveolus 105,106, and balance oil pocket 9,12 is cooperatively formed with piston 20.
The outer ring body of main rotating hub 1 is equipped with location hole of the spring 103, and spring assembly 8 is supported on the spring positioning on the outer ring body of main rotating hub 1
In the support ring of hole 103 and another spring assembly 13.The structure of main rotating hub 1 is shown in that attached drawing 2, section are I-shaped structure.
Main rotating hub 1 is equipped with cooling oilhole 102, and the both sides of cooling oilhole 102 are provided with pressure oilhole 101, in the perpendicular wall of " I " fonts
It is equipped with location hole of the spring 103, cooling oilhole 104 and balance oil pocket area 105,106.
The main rotating hub structure of the utility model is different from the prior art by welding the main rotating hub formed and two balances
Piston.By taking 7DCT300 speed changers as an example：5.5mm, support plate 4 and snap ring 3 are shortened using 1 left end of main rotating hub of the utility model
It accordingly arranges to the right, cooling oilhole 104 is open-minded to the right.It is corresponding that main rotating hub 1 is equipped with radially cooling oilhole 104 and circumferential direction
One ring recess, so that fluid is cooled down into inside and outside friction component.7 structure of piston becomes simple, and bending times are reduced 3 times, from
And Sheet Metal Forming Technology and relevant device are reduced, punching press salient point supports piston 7 in piston cap 5.
As shown in Figure 1：A kind of wet-type dual-clutch structure, by being equipped with axle sleeve 20,20 outside cylinder of axle sleeve in main rotating hub 1
Face coordinates with piston 7, and 20 inner cylinder face of axle sleeve is interference fitted with main rotating hub 1.On the external cylindrical surface of axle sleeve 20, piston 7 can axis
Piston stroke is realized to mobile.It is equipped with tapered opening 201 in the left side of the inner cylinder face of axle sleeve 20, pressure oilhole in main rotating hub 1
101 accordingly arrange to the right, corresponding with 201 axial position of tapered opening, and pressure oil is from the pressure oilhole 101 and axis in main rotating hub 1
The taper surface of set 20 enters pressure oil cavity 6.It is equipped with sealing surface 202, main rotating hub 1 and axle sleeve on the right side of the inner cylinder face of axle sleeve 20
Sealing ring 19 is equipped between 20, sealing ring 19 is first mounted in 1 corresponding seal groove of main rotating hub, and axle sleeve 20 is fitted in main rotating hub again
On 1, the sealing surface 202 on axle sleeve 20, with compression sealing ring 19 is merged, is realized the sealing to pressure oil cavity 9, is kept away with sealing ring 19
The pressure oil exempted from pressure oil cavity 9 leaks from the mating surface of axle sleeve 20 and main rotating hub 1.
Main rotating hub 1 is equipped with location hole of the spring 103, and spring assembly 8 is positioned radial through location hole of the spring 103, axial logical
The support ring positioning for crossing another spring assembly 13, to which spring assembly 8 is arranged to the right, and saves a spring supporting
Ring.Since spring assembly 8 is arranged to the right, piston 7 has done simplified design, reduces bending.Piston cap 5 is equipped with salient point to support back
Piston 7 behind position.
Main rotating hub 1 is equipped with equilibrium oil alveolus 105,106, and equilibrium oil alveolus 105,106 is matched with piston 7, piston 13 respectively
It closes and forms balance oil pocket 9,12.Cooling oil enters from the cooling oilhole 102 in main rotating hub 1, then the bullet being equipped with by main rotating hub 1
Spring location hole 103 and cooling oilhole 104 in engaging friction component 10,11, realize the cooling to friction component 10,11.
Due in main rotating hub 1 pressure oilhole 101 and spring assembly 8 arrange that main rotating hub 1 is retracted also therefore to the right to the right
5.5mm, bearing 2, snap ring 3, support plate 4, piston cap 5 arrange to the right 5.5mm, input hub 23, output hub 22 and output 21 axis of hub
5.5mm is accordingly shortened to length.Therefore, double clutch axial overall length shortens 5.5mm, and the transmission shaft of the double clutch is housed
5.5mm is shortened to total length.
By being newly equipped with axle sleeve 20 and sealing ring 19 in main rotating hub 1.Axle sleeve 20 coordinates with piston 7 and main rotating hub 1, realizes
Piston 7 is axially moved and oil duct function, sealing ring 19 can with sealed pressure oil, avoid pressure oil from main rotating hub 1 and axle sleeve 20 it
Between leak.For the utility model by changing axial space with radial space, the axial direction and oil hole of the piston 7 and its stroke that make are axial
Length is overlapped, to reduce axial overall length.The equilibrium oil alveolus 105,106 being equipped with by main rotating hub 1 cancels balance and lives
Plug, balance oil pocket 9,12 are realized by piston 7 and the cooperation of main rotating hub 1.It is equipped with 103 location hole of spring by main rotating hub 1, is removed
The spring supporting ring on 8 right side of spring assembly, makes location hole of the spring 103 and another groups of springs of the spring supporting in main rotating hub 1
In the support ring of part 13.To reduce spring assembly direction axial overall length.
Pass through the reduction of part and the optimization of structure, wet-type dual-clutch weight saving.In addition to this, due to wet type it is double from
Clutch axial distance is shorter, and the axis and shell on the speed changer equipped with the wet clutch can also axially shorten, this practicality is new
Type makes wet-type dual-clutch and transmission shaft to length reduction 5.5mm, more compact, is conducive to client's arrangement, will adapt to more
Vehicle environment.And transmission assembly weight saving about 0.5kg, meet the lightweight demand of vehicle.Pass through the reduction of part
And part-subassemble standard, the simplification of part structure, the simplification of technique, the mitigation of weight, therefore cost is lower.
