Abstract
The utility model relates to a torsion damper of variant rigidity for clutch on motor vehicle, which comprises a damper disc, a damper spring, a driven disc hub, a driven disc noumenon, and damping pieces. The damper disc is connected with the driven disc noumenon. The driven disc hub fixed with the damper pieces at both sides of the driven disc hub is held between the driven disc noumenon and the damper disc and connected up together by rivets. A gap existing between the rivets and the driven disc hub is fixed with the damper pieces. The driven disc noumenon is opened with a plurality of windows which go through the driven disc noumenon to the damper disc, within which the damper spring is arranged. The utility model is characterized in that: the damper spring is of a cylindrical helical spring of variant pitch. In the torsion damper, the cylindrical helical spring of a variant rigidity is adopted and the feature of torsion of the variant rigidity can be better realized and the structure is not only simplified, but vibration performance of the torsion damper can be improved.
Description
Affiliated technical field
The utility model provides a kind of automobile clutch with becoming the rigidity torsional vibration damper, belongs to technical field of automobile parts.
Background technique
At present, extensively adopt four-stroke internal combustion engine as power on the automobile, and cooperate transmission system to drive automobilism.The torque that motor passes in the automotive transmission is constantly to change periodically, and this just makes and produces torsional vibration in the power train.If the self-excited oscillation frequency of the frequency of this vibration and power train coincides, just will resonate, the Parts for Power Train life-span is had a significant impact, also can work the mischief to the member is healthy.In addition, under the situation of cut-off clutch not and when carrying out emergency braking or fierce engaging clutch, will cause very big impulsive load in moment, and shorten the working life of part power train.For fear of resonance, relax the suffered impulsive load of power train, extensively adopt torsional vibration damper on automobile clutch, its working principle is: the motion compresses damper spring of driven disc body and damper disk, damper spring promotes clutch plate hub, transmitting movement and moment; When impulsive load, clutch plate hub is swung with respect to the driven disc body is relative with damper disk with the resistance of shock absorber sheet, thereby consumes the vibrational energy attenuation vibration by friction.
In existing scheme, one group of damper spring of the employing that has, the suffered pressure of spring is linear with distortion, i.e. the distortion of torsional vibration damper torque transmitted and torsional vibration damper (being the relative angular displacement distortion between clutch plate hub and the damper disk) is linear.The torsional vibration damper of some automobile clutch adopts the different damper spring of two or more groups rigidity, and spring-loaded length of window is made size differ, and the method for utilizing spring successively to work successively obtains to become stiffness characteristics.Practice shows that the torsional vibration damper service behaviour that adopts multistage rigidity is than adopting the good of single-stage, and still along with the increase of spring rate progression, structure and manufacturing become increasingly complex.Adopt the vibration damper of rubber shock absorber spring to have nonlinear characteristics, effectiveness in vibration suppression is better, and the back is rotten but rubber is heated easily.
The model utility content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, keeping on the original torsional vibration damper basis simple in structure, can realize that the better automobile clutch of function, the damping property of multistage and stepless rigidity torsional vibration damper is with becoming the rigidity torsional vibration damper.Its technological scheme is:
Automobile clutch is with becoming the rigidity torsional vibration damper, comprise damper disk, damper spring, clutch plate hub, driven disc body, damping fin, wherein damper disk and driven disc body are fixed together, the clutch plate hub that both sides are fixed with damping fin is clamped between driven disc body and the damper disk, pass by rivet and to link together, rivet and both sides are fixed with between the clutch plate hub of damping fin and have the gap, can relatively rotate so that both sides are fixed with between the clutch plate hub of damping fin and damper disk and the driven disc body; Have a plurality of windows that penetrate the driven disc body to damper disk on the driven disc body, damper spring is arranged in the window, it is characterized in that: damper spring is to adopt to switch political loyalty apart from cylindrically coiled spring.
Its working principle is: during the clutch transmits engine torque, the suffered friction torque of driven disc at first passes to driven disc body and damper disk, is delivered to clutch plate hub through damper spring again; Spring is compressed during the damper spring transmitting torque, absorbs the impact that torque ripple brings; Simultaneously, the torsional vibration of power train makes clutch plate hub with respect to driven disc body and damper disk reciprocating vibration, and the resistance of shock absorber sheet that is installed on the clutch plate hub can consume the energy of torsional vibration, thereby decays this vibration.In this torsional vibration damper, damper spring has adopted the cylindrically coiled spring that becomes firm, can realize becoming preferably the rigidity twisting characteristic, so not only simplifies the structure but also can improve the torsional vibration damper damping property.
The utility model compared with prior art, because damper spring adopts the cylindroid helicalcoil compression spring of the distance of switching political loyalty, promptly the pitch of damper spring is different, obtains becoming the rigidity elastic characteristic, can realize the function of multistage and stepless rigidity torsional vibration damper, improve the damping property of vibration damper.
