A kind of quick oil-discharging valve arrangement is currently there are, to assist wet clutch emptying.This structure is because with such as
Lower shortcoming and limitation be present.Its shortcoming is as follows：(1) when clutch engages, quick drain valve can not in time close or can not
Closing causes clutch oil pocket fluid to be discharged into fuel tank, and clutch oil pocket oil pressure is established slowly, and clutch binding time is long；(2)
During throw-out-of clutch, quick drain valve can not open in time so that clutch oil pocket fluid can not exclude completely, clutch fluid
Because the effect of centrifugal force produces centrifugal oil pressure, clutch plunger is caused to move, pressing friction piece and steel disc so that friction plate and steel
Piece is in sliding state of rubbing；(3) manufacturing cost is high.
Utility model content
For drawbacks described above present in prior art, the purpose of this utility model is to provide a kind of change with damping hole
Fast case wet clutch, it can solve the problem that the incomplete problem of wet clutch emptying.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of gearbox wet clutch with damping hole, including hub, main shaft, clutch plunger, antithesis outside clutch
Hub in steel disc, friction plate, platen and clutch, one end of main shaft, which is fixed, is connected in the outer hub of clutch, make the other end of main shaft with from
An oil pocket is formed between the outer hub of clutch, hub is located at oil pocket in clutch plunger, pairing steel sheet, friction plate, platen and clutch
Interior, clutch plunger is on one end of main shaft, and one end of hub is located at the other end of main shaft in clutch, and hub is another in clutch
One end is in contact with clutch plunger, and platen is connected in the top of hub one end in clutch, and pairing steel sheet and friction plate are located at clutch
Between device piston and platen, damping hole is offered on the outer hub of clutch.
Spring support is also connected with described main shaft, spring support is provided with return spring with clutch plunger.
Described pairing steel sheet and friction plate is interval with several pieces.
Described damping hole is opened in the outward flange of the outer hub of clutch.
Described damping bore dia≤2mm.
Described damping hole length is less than or equal to 15mm.
Oil duct is offered on described main shaft, oil duct is connected with oil pocket.
In above-mentioned technical scheme, a kind of gearbox wet type clutch with damping hole provided by the utility model
Device, the function of quick drain valve can not only be reached, and it is simple in construction, it is easy to accomplish, reduce cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of gearbox wet clutch with damping hole provided by the utility model, including
Hub 6 in the outer hub 1 of clutch, main shaft 8, clutch plunger 2, pairing steel sheet 3, friction plate 4, platen 5 and clutch, the one of main shaft 8
End is fixedly connected on the outer hub 1 of clutch, makes to form an oil pocket 9 between the other end of main shaft 8 and the outer hub 1 of clutch, and from
Hub 6 is arranged in oil pocket 9 in clutch piston 2, pairing steel sheet 3, friction plate 4, platen 5 and clutch, and clutch plunger 2 is installed
On one end of main shaft 8, it can be moved on main shaft 2 by hydraulic oil, the lower end of clutch plunger 2 is also provided with a platform
Rank, one end of hub 6 is located at the other end of main shaft 8 in clutch, the other end of hub 6 and the lower end of clutch plunger 2 in clutch
Step is in contact, and forms a cavity 10, and platen 5 is connected to the top of one end of hub 6 in clutch, pairing steel sheet 3 and friction
Piece 4 is respectively provided with several pieces, is arranged in interval superposition between clutch plunger 2 and platen 5, the outer 2 outer peripheral position of hub of clutch
On offer damping hole 101, fluid is thrown toward the outer of the outer hub 2 of clutch under the influence of centrifugal force in wet clutch oil pocket 9
Edge, fluid are discharged in fuel tank by damping hole 101.
When wet clutch engages, the hydraulic oil that hydraulic pump provides is injected into wet clutch through the oil duct 11 on main shaft 8
Oil pocket 9, and oil pressure is quickly established in oil pocket 9, oil pressure promotes clutch plunger 2 to move right, by pairing steel sheet 3 and friction
Piece 4 is compressed, and friction is produced between pairing steel sheet 3 and friction plate 4, utilizes caused frictional force between pairing steel sheet 3 and friction plate 4
Power is delivered to load by main shaft 8.
When wet clutch disengages, hydraulic pump is no longer wet clutch fuel feeding, and the fluid in wet clutch oil pocket 9 leads to
The oil duct 11 crossed on main shaft 8 flows into fuel tank, and due to the effect of centrifugal force, the inside points fluid of oil pocket 9 is thrown toward the outer hub 2 of clutch
Outward flange, the fluid of this part will be drained into fuel tank by damping hole 101.
Preferably, being also connected with spring support 12 on described main shaft 8, spring support 12 is provided with return with clutch plunger 2
Spring 7, to the return of clutch plunger 2.
Preferably, described 101 diameters of damping hole≤2mm, the length of damping hole 101 is less than or equal to 15mm, and damping hole 101 is adopted
With elongated hole structure, its size should be able to make the pressure in oil pocket 9 reach specified pressure, wet clutch is smoothly engaged, and pass
Graduating power, if damping hole 101 is oversized, wet clutch failure mode will be caused.
In summary, the design of the utility model increase damping hole, the emptying process of wet clutch can not only be accelerated,
Fluid in wet clutch oil pocket is excluded completely, and the fluid that damping hole sprays can also play splashing profit to other parts
Sliding effect.A damping hole is opened in the outward flange of hub outside wet clutch, and no matter clutch plunger is in what position, can ensure wet
The fluid of formula clutch oil intracavitary can be flowed out by damping hole, thus ensure the fluid in wet clutch oil pocket in clutch
Device excludes completely when disengaging, and is kept completely separate friction plate and pairing steel sheet.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as to restriction of the present utility model, as long as in spirit of the present utility model, to described above
Change, the modification of embodiment will all fall in Claims scope of the present utility model.
