Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
First embodiment
In conjunction with shown in Fig. 1 to Fig. 2, the wet-type dual-clutch assembly of the present embodiment includes the first clutch 1 of coaxial arrangement
With second clutch 2, for control first clutch 1 separation with combine the first executing agency 3 and for control second from
The second executing agency 4 clutch 2 separation and combined.Wherein:
First clutch 1 include the outer plate rail 10 of annular, the clutch disc group 12 in the surrounded space 11 of outer plate rail 10,
And the cut spring 13 in compressive state in clutch disc group 12 between two neighboring clutch disc 120.Outer plate rail
10 have ring baffle 100, and baffle 100 is located at the axial side of clutch disc group 12, and is equipped with several circumferentially spaced settings
Jack 101.
First executing agency 3 includes the rigid platen 30 of annular, rigid platen 30 include the body part 31 being disposed radially, with

Jack 201 simultaneously protrudes into space 21, first pressure refer to 42 close to clutch disc group 22 axial end portion and cut spring 23 in axial direction
Upper alignment.
When second clutch 2 combines, rigid platen 40 is moved along the axial direction close to baffle 200, rigid platen 40
On it is all first pressure refer to 42, second pressure refer to 43 along axial compression clutch disc groups 22 so that each in clutch disc group 22
Clutch disc 220 is tightly abutted together the transmitting to realize torque.At the same time, cut spring 23 is constantly compressed.
In the present embodiment, when second clutch 2 combines, refer to 42 regions to offset with the first pressure in clutch disc group 22
The distance between central axes of clutch disc group 22 refer to 43 regions to offset greater than in clutch disc group 22 for pressing with second
The distance between central axes of clutch disc group 22, so that the first pressure refers to the radial outside area of 42 extruding clutch disc groups 22
Domain, the second pressure refer to the radially inner side regions of 43 extruding clutch disc groups 22, that is, the second pressure refers to that 43 press with first and refer to 42 extruding clutches
The different zones in the radial direction of device piece group 22.Wherein, the first pressure refers to that 42 are mainly used to reduce clutch when second clutch 2 combines
The possibility that device piece 220 is locally deformed with, the second pressure refer to that 43 are mainly used to compress clutch disc group 22.
It makes a concrete analysis of as follows:
Second clutch 2 under bonding state, due to first pressure refer to 42 close to clutch disc group 22 axial end portion with point
It is aligned from spring 23, therefore refers on region and clutch disc group 22 that 42 offset in clutch disc group 22 with the first pressure in the axial direction
It is at least a part of overlapping with the region that cut spring 23 offsets, so, when second clutch 2 combines, cut spring
The moment of flexure that 23 restoring force applies to the regional area of clutch disc 220 is referred to by the first pressure 42 to the partial zones of clutch disc 220
The moment of flexure that domain applies at least balances out a part, thus reduces the possibility that clutch disc 220 is locally deformed with.
Overcome since the restoring force of cut spring 23 refers to 42 by the first pressure, therefore the second pressure refers to that the pressing force of 43 applications is not necessarily to
Overcome the restoring force of cut spring 23, can all compress clutch disc group 22, is applied to reduce to rigid platen 40
The pressing force added.
The axially spaced setting of rigid platen 40 in rigid platen 30 and second clutch 2 in first clutch 1, makes
First clutch 1, combinations in second clutch 2 when, rigid platen 30 will not be interfered with rigidity platen 40.The
The outer plate rail 20 in outer plate rail 10 and second clutch 2 in one clutch 1 is fixedly installed, and the two is rotated synchronously.
In the present embodiment, each clutch disc 120 in clutch disc group 12 includes the active set gradually along axial direction
Steel disc 121 and driven friction disk 122, the driven friction disk 122 in the two of arbitrary neighborhood clutch disc 120 is opposite in the axial direction
Setting.The outer diameter of active steel disc 121 is greater than the outer diameter of driven friction disk 122, and cut spring 13 is located at adjacent two
Between a active steel disc 121, and it is located at the radial outside of driven friction disk 122.
It is used to refer to the region and clutch that 32 offset with the first pressure in the alternative of the present embodiment, in clutch disc group 12
The distance between central axes of piece group 12, might be less that be used to refer to the second pressure in clutch disc group 12 region that 33 offset with
The distance between the central axes of clutch disc group 12, and be used to refer to the second pressure in clutch disc group 12 region that 33 offset with from
The region of movable friction plate 122 at least partially overlaps.The technical solution of the present embodiment has relative to the technical solution of the alternative
Have the advantage that: the second pressure refers to that the pressing force of 33 applications can be applied directly to region corresponding to driven friction disk 122, so that
Each driven friction disk 122 in clutch disc group 12 can be more firm with adjacent driven friction disk 122, active steel disc 121
It is abutted together by ground, so as to realize the transmitting of bigger torque.
