Background technique
Friction clutch is widely used in current motor vehicle, can be in driving by this friction clutch
Middle transmitting torque interrupts torque transmitting.In order to transmit torque, friction clutch needs frictional disk.Frictional disk usually has energy
The clutch compressing disc with the antitorque connection of transmission input shaft enough moved axially, the clutch compressing disc can be opposite by two
Friction pair compress.In addition, friction clutch also has driver blade, such as leaf spring, for operating clutch compressing disc.
102015224065 A1 of patent document DE discloses a kind of friction clutch, wherein can operate by leaf spring
Clutch compressing disc, wherein can be axially with resiliently deflectable solid by the leaf spring by multiple immobilising devices (such as rivet)
It is scheduled on clutch case.When clutch is closed, clutch compressing disc can compress frictional disk, so as to by the torque of drive shaft
It is transmitted to the input shaft of speed changer.
In this common friction clutch, there are such problems: during clutch separation or engagement, from
Clutch platen is transmitted piece pull-up or pressure, i.e., when clutch compressing disc is not at the state being compacted, clutch compressing disc may
Generate certain vibration, it is thus possible to the frequency of each rank synthesis intrinsic frequency of clutch compressing disc and whole system can be caused to occur altogether
Vibration causes to issue very big noise and damages the clutch apparatus.
In order to reduce this influence, a solution is proposed by 102015201890 A1 of DE: being filled in friction clutch
In setting, equipped with clutch compressing disc and the pairing disk being axially movable, friction plate is located between clutch compressing disc and pairing disk, is being matched
To a kind of adjustment device is arranged on disk, for being adjusted between clutch compressing disc and pairing disk according to the friction law of friction plate
A kind of activation device for activating the adjustment device is arranged in spacing on clutch compressing disc.Although this design can change
Kind techniques as described above problem, but due to structure is more complex, higher cost be not suitable for being used in structure space it is more compact
In clutch apparatus, thus it is not widely used.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of improved clutch apparatus, more particularly in clutch
Platen is transmitted piece pull-up or pressure, i.e., when clutch compressing disc is not at the state being compacted, adjusts the vibration of clutch compressing disc,
It avoids resonating.
In order to solve the above-mentioned technical problem, it is proposed that a kind of clutch apparatus, has clutch case, clutch compressing disc
With the driver blade for being used to operate the clutch compressing disc, wherein driver blade is fixed on the clutch case by immobilising device
On.According to the present invention, one or more friction resilient parts are centered in the clutch device, especially setting friction spring, institute
Friction resilient part is stated to be pressed against on the outer surface of clutch compressing disc by pretightning force.Clutch compressing disc be transmitted piece pull-up or
During pressure, since the pretightning force of friction resilient part can generate biggish rub between friction resilient part and clutch compressing disc
Wipe power, it is thus possible to the vibration of clutch compressing disc, dissipation vibrational energy are reduced, and damping action can also be played, changes frequency,
To avoid resonating.
Clutch apparatus according to the present invention can be friction clutch, be also possible to other types of clutch.This
The application field of invention is also not limited to clutch field, above-mentioned technical proposal be also applicable in it is other have vibration problem be
In system.It can be leaf spring for operating the driver blade of clutch compressing disc, be also possible to diaphragm spring.It is operated in clutch apparatus
When, make clutch compressing disc mobile to friction plate by driver blade or clutch compressing disc is made to leave friction plate, i.e. clutch
Platen is not compacted, and in this process, clutch compressing disc would generally generate bigger vibration, it is thus possible to can cause from
The frequency of each rank synthesis intrinsic frequency of clutch platen and whole system resonates.In order to avoid this resonance, one of solution
Certainly scheme is exactly the frequency for reducing vibration or changing clutch compressing disc.Friction resilient part is pressed on the outer surface of clutch compressing disc
It can play and reduce or eliminate clutch compressing disc quiveringly purpose.
According to embodiment of the present invention, the friction resilient part has fixation section and friction section.It is described solid
Section is determined for fixed friction elastic component, friction resilient part can be fixed on clutch case or driver blade by fixation section
On.Preferably, by driver blade and fixation section by common immobilising device, especially rivet is fixed on clutch case.Root
According to other embodiment of the invention, additionally it is possible to which fixation section is fixed on biography by the connection types such as welding, being bolted
On movable plate or clutch case.
Embodiment according to the present invention, the friction section are pressed against the outer surface of clutch compressing disc by pretightning force
On.Preferably, the friction section has elasticity, it is thus possible to correspondingly be adjusted according to the amplitude of clutch compressing disc and frequency
The size of the pretightning force of friction resilient part.
Other embodiment according to the present invention, additionally it is possible to center multiple friction sections in clutch device, respectively
It is pressed against on the different outer surfaces of the clutch compressing disc, thus can when clutch compressing disc has multiple direction of vibration
Frictional force is generated on corresponding direction of vibration, therefore plays preferably effectiveness in vibration suppression.Other embodiment party according to the present invention
Formula, the face that friction section is in contact with clutch compressing disc has special construction, such as arc refers to structure (undulatory structure), to change
Frictional behavior between kind two antithesis contact surfaces shows so as to improve the stress of friction resilient part.
Detailed description of the invention
According to as follows in conjunction with attached drawing to the explanation of embodiment, the features and advantages of the present invention can be explained in more detail.It is attached
Figure are as follows:
Fig. 1 shows the schematic diagram of the embodiment of clutch apparatus according to the present invention.
Specific embodiment
Fig. 1 shows friction clutch according to the present invention, has clutch case 1, driver blade 2 and clutch compressing disc 3.It is described
Driver blade 2 is made of three pieces leaf spring in the present embodiment, is also conceivable to driver blade others embodiment certainly, such as by more
Or more taper-leaf spring is constituted, or is made of the spring part of other forms.Driver blade is fixed on clutch case 1 by rivet 4
On.In friction clutch according to the present invention, it is additionally provided with friction spring 5.The friction spring 5 is also consolidated by the rivet 4
Determine onto driver blade 2；The friction spring can also otherwise, such as welding or shape are fixedly connected to clutch
On device lid 1 or on driver blade 2.
In this embodiment, there are two sections, i.e. fixation section and friction section for the tool of friction spring 5.It will rub by rivet 4
The fixation section for wiping spring 5 is fixed on driver blade 2, and the section that rubs is crushed on clutch compressing disc 3 by certain pretightning force
Outer surface on.Therefore, there is friction between friction spring 5 and clutch compressing disc 3.It shakes when clutch compressing disc is lifted
When dynamic, friction spring 5 can play the role of vibration damping by friction herein, to eliminate or reduce the vibration of clutch compressing disc
It is dynamic.Frictional force caused by clutch compressing disc 3 and friction spring 5 should offset the vibration of clutch compressing disc 3.If clutch pressure
