Description
Technical field
The utility model relates to technical field of transmission equipment more particularly to a kind of clutches.
Background technique
Wet-type dual-clutch is divided into two kinds of dry type, wet type, wherein there is wet-type dual-clutch pressure to be evenly distributed, radiate
Well, the advantages that small, transmitting torque capacity is big, without specially adjusting friction plate gap is worn, has been obtained in many vehicles extensively
Using.
In order to meet riding comfort, existing way, first is that return spring is added below piston plate, in clutch point
From when, return spring can allow piston plate returning quickly；In clutch engagement, control pressure need to overcome nonlinear elasticity spring force into
Row engagement, transmitting torque, reduce shock extent；Second is that cut spring, cut spring are arranged between two neighboring clutch disc
Between two neighboring steel disc, it is located at friction plate radial outside.In clutch separation, cut spring can allow two clutches
Device piece quick separating makes to keep uniform gap to reduce trailing moment between each；When clutch combines, cut spring compression energy
Enough reduce the impact of pressing force.
But there are following deficiencies for the wet-type dual-clutch of above-mentioned setting return spring: in engaging process, although piston plate
It is acted on by spring-return power, is reduced in conjunction with speed, but power is applied to the moment in clutch disc, clutch disc approximation is not
Dynamic, speed mutates, and impact is still rigid.Secondly piston plate pressure refers to the clutch for being applied to and being connected on clutch housing
Piece group can apply a moment of flexure to clutch disc, cause clutch disc local deformation.Furthermore existing return spring mostly uses week to set
Helical spring, holddown spring are directly contacted with platen, and tempering is easy to cause to fail, and centrifugal force is allowed to be bent outwardly under high revolving speed,
Pressing force and torque transmission capacity are remarkably decreased, and spring leans against on positioning seat, contact site serious wear.

When engagement, ECU controls the supply of oil pressure by automatic speed variator hydraulic system, and hydraulic oil flows through oil by the oilhole in main rotating hub
Oil duct in set pushes pressure chamber piston plate 3 into the pressure chamber of clutch, is that 7 gap of clutch disc group is eliminated, gradually
It compresses, is connected by the spline between piece group and shell, the riveting between shell and main driven shaft, so that principal and subordinate moved end rotational speed difference disappears
It removes, torque transfer.
Wherein in the first embodiment of the application, the elastic parts 4 includes adjustment card of the holding on 2 inner wall of outer housing
The waveform spring piece 42 of spring 41 and one end holding between on inner housing 1, the other end activity of the waveform spring piece 42 are taken
It connects on adjustment circlip 41, the side of the waveform spring piece 42 can be abutted with clutch disc group 7.Wherein waveform spring piece 42 exists
In the application, ring plate of the holding on 1 outer wall of inner housing can be regarded as in fact, and the ring plate has certain elasticity.Wherein
Waveform spring piece 42 can also be with the continuous holding of multiple elastic pieces on 1 periphery of inner housing, and specific structure is not described in detail herein.Adjustment
Circlip 41 can also be ring plate either continuous elastic piece, only adjust as the mentality of designing of waveform spring piece 42
Circlip 41 is corresponding with 42 position of waveform spring piece.In order to install and realize function, the internal diameter that circlip 41 is adjusted in the application is less than
The outer diameter of waveform spring piece 42 during preventing clutch disc group 7 from will compress in this way, occurs stopping situation not in place.
The middle part of the waveform spring piece 42 is equipped with to the protrusion 43 of 7 side of clutch disc group protrusion, the protrusion 43 and
The output end of pressure chamber piston plate 3 is arranged on the same straight line for being parallel to pivot center.Using coaxial setting, so that pressure
Chamber piston plate 3 can effectively avoid not being moment of flexure brought by coaxial stress when pressing clutch disc group 7, reduce clutch disc
Impact force suffered by group 7, avoids its deformation, can provide buffering very well, reduces vibration when contact and noise.
In order to increase restoring force, so that 7 quick separating of clutch disc group, between the outer housing 2 and pressure chamber piston plate 3
It is additionally provided with the first dish-shaped return spring 5 for reset, the described first dish-shaped return spring 5 is coaxially set with pressure chamber piston plate 3
