Abstract
The invention discloses a damper provided with a damping system protecting device and belongs to the field of automobile accessories. The damper aims to overcome the defects of an existing torsional damper by transforming the torsional damper. According to the damper, a disc hub limiting base is installed on a disc hub, a disc hub side limiting pillar is fixedly installed on the disc hub limiting base, a disc hub side anti-disengaging table is arranged at the top end of the disc hub side limiting pillar, and a disc hub side plastic elastic limiting device is tightly arranged outside the disc hub side limiting pillar and the disc hub side anti-disengaging table in a plastic merge mode; a driven disc limiting base is installed on a damping disc and a driven disc, a driven disc side limiting pillar is fixedly installed on the driven disc limiting base, a driven disc side anti-disengaging table is arranged at the top end of the driven disc side limiting pillar, and a driven disc side plastic elastic limiting device is tightly arranged outside the driven disc side limiting pillar and the driven disc side anti-disengaging table in a plastic merge mode; the outer diameter of the disc hub side plastic elastic limiting device and the outer diameter of the driven disc side plastic elastic limiting device are smaller than the inner diameter of a spring, and the disc hub side plastic elastic limiting device and the driven disc side plastic elastic limiting device are arranged in the spring. The damper is simple in structure and convenient to install, the service life of the torsional damper is prolonged, and vibration and noise are reduced.
Description
Technical field
The invention belongs to auto parts machinery field.
Background technique
Automobile clutch plays torsion pass, cuts off the multiple functions such as power, vibration damping and overload protection, the performance of the whole automobile of good bad influence of its quality in power train.In vehicle traveling process, because internal combustion engine is uneven, changing of torque cycle can cause driveline vibrations.The reduction noise aspect that is applied in of torsional vibration damper plays very large effect.
Conventional torsion vibration absorber forms primarily of two-part: elastic element and damping member.When clutch uses, elastic element can be compressed due to torsional interaction, instantaneous compared with under the effect of high pulling torque, elastic element can be compressed to the limit by force, causes spring also dead, so repeatedly, make the lost of life of elastic element, even rupture, when clutch is in High Rotation Speed state, elastic element lost efficacy will cause noise and vibration, makes whole power train generation abnormal sound.
Summary of the invention
The object of the invention is by again transforming torsion vibration absorber, to solve the vibration damper of the band vibration insulating system protective gear of the shortcoming that existing torsion vibration absorber exists.
The present invention is provided with hub position limit socket in hub, hub position limit socket is installed with hub side limited post, and limited post top, hub side is hub side anticreep platform, and closely moulding conjunction outward at hub side limited post and hub side anticreep platform has hub side plasticity elastic limit; Damping disk(-isc) and driven disc are provided with driven disc position limit socket, driven disc position limit socket is installed with driven disc side limited post, limited post top, driven disc side is driven disc side anticreep platform, and closely moulding conjunction outward at driven disc side limited post and driven disc side anticreep platform has driven disc side plasticity elastic limit; The external diameter of hub side plasticity elastic limit and driven disc side plasticity elastic limit is less than spring inside diameter and is placed in spring.
Structure of the present invention is simple; be convenient to install, when torsion vibration absorber reaches capacity torsion angle, avoid shock-absorbing spring also dead; thus improve the working life of torsion vibration absorber, the torsion vibration absorber ultimate torsional angle protection limit structure of the vibration that the decay of minimizing spring and fracture bring and noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the present invention's mounting point schematic diagram on clutch driven plate;
Fig. 3 is the test curve figure of conventional torsion vibration absorber;
Fig. 4 is the test curve figure of torsion vibration absorber of the present invention.
Embodiment
The present invention is provided with hub position limit socket 2 in hub 1, hub position limit socket 2 is installed with hub side limited post 12, limited post 12 top, hub side is hub side anticreep platform 3, and outside hub side limited post 12 and hub side anticreep platform 3, closely mould conjunction has hub side plasticity elastic limit 4; Damping disk(-isc) 9 and driven disc 10 are provided with driven disc position limit socket 8, driven disc position limit socket 8 is installed with driven disc side limited post 7, limited post 7 top, driven disc side is driven disc side anticreep platform 11, and outside driven disc side limited post 7 and driven disc side anticreep platform 11, closely mould conjunction has driven disc side plasticity elastic limit 6; The external diameter of hub side plasticity elastic limit 4 and driven disc side plasticity elastic limit 6 is less than spring 5 internal diameter and is placed in spring 5.
The present invention is that the centre of hub window edge has indent restraining groove, and hub position limit socket clamping is inner at restraining groove;
Hub position limit socket and limited post are combined for moulding, and position limit socket are designed with boss anticreep;
There is the indent restraining groove of extruding the window side of driven disc, and driven disc position limit socket clamping is inner at the window indent restraining groove of driven disc;
Driven disc position limit socket and positioning seat are designed with boss anticreep for moulding to be combined on driven disc position limit socket;
When clutch drived disk assy reverses, after reach capacity moment of torsion and ultimate torsional angle degree, shock-absorbing spring and dead before, limited post acts on positioning seat, plays position-limiting action, avoids shock-absorbing spring completely and dead, thus reaches the effect of protection vibration insulating system.
The present invention adds vibration insulating system limited post in traditional torsional vibration damper; achieve the effect of protection vibration insulating system; when reaching the torsion limit; reversing limited post can protect vibration insulating system overload occurs and lost efficacy; in the using process of reality; limited post can provide position limitation protection to shock-absorbing spring, thus reaches the object extending vibration damper working life.
When windup-degree increases gradually, the suppressed range of vibration insulating system will strengthen further, and limited post can avoid limited compression, extend the working life more than 2 times of torsional vibration damper.
When torsional vibration damper carries out work, torsional stiffness can be changed by the present invention, be equivalent on the basis of original rigidity, increase one-level vibration damping rigidity, the curve of torsional stiffness can be recorded by clutch drived disk assy torsion testing machine, prove that application clutch drived disk assy torsional stiffness curve of the present invention is after clutch drived disk assy reaches capacity windup-degree, what rigidity can be made to increase is more smooth-going, vibration is avoided to produce noise, before and after the curve of torsional stiffness, contrast is: the technology rigidity that (see Fig. 3 and Fig. 4) is traditional first remains unchanged, raise fast afterwards, can cause vibrating abnormal sound, technology of the present invention can ensure that rigidity slowly raises, reach capacity.
