Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is made the most in detail
Thin explanation.
This utility model automatic gear-box wet clutch structure, as it is shown in figure 1, include clutch hub and friction plate group
10, being provided with pressurized in clutch hub can the piston of pressing friction plate group 10；As shown in Figure 1, 2, the piston in this utility model
Including being located at the pressing part 6 of outer ring, the locating part 8 of inner ring and be located between pressing part 6 and locating part 8 there is certain elastic film
Sheet elastic component 7.In wet clutch, acted on by oil pressure by piston, overcome the elastic force of membrane flexive part 7, pressing part 6 is pressed
Close friction plate group 10, it is achieved clutch engages；When oil pressure discharges, make pressing part 6 return, friction plate by membrane flexive part 7
Group 10 release, thus reach the purpose that wet clutch unclamps.
In this utility model, form a space closed between piston and clutch hub, by being passed through pressure oil control
Piston controls to realize the folding to clutch.The outside wall surface of pressing part 6 contacts laminating with clutch hub outer ring 1.Locating part 8 overlaps
It is connected on clutch hub inner ring 2, and is socketed for matched in clearance.Membrane flexive part 7 main body is the frustum structure of annular, ties at frustum
The two ends of structure are provided with the overlap edge that overlap joint is connected on pressing part 6 and locating part 8 respectively of bending, and frustum structure is spacing by connecting
One end of part 8 to connect pressing part 6 one end its enclose conglobate diameter and become larger.Membrane flexive part 7, as it is shown in figure 1, its
Section structure is zigzag, as shown position, and when the space injection pressure oil of side, membrane flexive part 7 stress, in this direction
On the elastic force of itself can be overcome to deform, the pressing part 6 being connected to its one end presses to friction plate group 10, when oil pressure discharge, diaphragm
Elastic component 7 is self-return under the resilient force of himself, and pressing part 6 is also with membrane flexive part 7 return, and friction plate group 10 takes off
From.
In this utility model, as shown in Figure 1, 2, pressing part 6 be annular lid-like, be similar to cup lid structure, have on
End cap face and the cover rim of bending, i.e. the section of its annular lid-like is 7 character form structures.In Relative friction sheet group 10 one end (i.e.
Above-mentioned described cover rim) it is provided with the crimp rings that turnover contact is crimped on friction plate.The outer ring laminating of crimp rings and friction plate, can
Ensure stable pressure force, so that friction plate group 10 is steadily effectively combined.
In this utility model, pressing part 6, locating part 8 and membrane flexive part 7 are connected as an overall structure, can use weldering
Connect in succession, can its axial dimension relatively reduced.For preferably being sealed space, protruding in the bending of pressing part 6 lid-like
Place is provided with outer ring sealing member 3, is tightly connected with clutch hub outer ring 1.Inner side at locating part 8 with clutch hub inner ring 2 laminating
Face is provided with inner ring sealing member 4.Locating part 8 medial surface is provided with installs the cannelure placing inner ring sealing member 4.At clutch hub
Inner ring 2 is provided with and is positioned at locating part 8 side, prevents piston to be stressed and produces the limited location snap ring 9 moved axially.In clutch hub
Circle is provided with the oil-in 5 leading to seal oil chamber.
Piston structure in this utility model, is made up of three widgets, and welding is in an entirety；Pressing part 6, it is achieved with
The sealing of clutch hub outer ring 1, and it is supplied to friction plate group 10 pressure；Locating part 8, realizes sealing with clutch hub inner ring, and
Axially location is realized together with limited location snap ring 9；Membrane flexive part 7, it is provided that spring force；When piston is overcome by oil pressure effect, pressure
Membrane flexive part 7 (now membrane flexive part 7 stores elastic potential energy), pushes pressing part 6 and is pressed in friction plate group 10, it is achieved clutch
In conjunction with, when oil pressure disappears, the elastic potential energy release of membrane flexive part 7, make pressing part 6 return, thus realize clutch and unclamp.
This utility model automatic gear-box wet clutch structure, simple in construction, amount of parts reduces, the axial chi of assembly
Very little reduction, so that the axial dimension of whole clutch assembly significantly reduces, arranges extremely advantageous to FCL；Clutch simultaneously
The composition of assembly is relatively easy, parts cost and production assembly cost all relative reduction, has preferable application prospect, has
Stronger practicality.
Above in conjunction with accompanying drawing, this utility model is exemplarily described, but this utility model is not limited to above-mentioned
Mode, as long as using the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out or directly applying
In other occasion, all fall within protection domain of the present utility model.
