Abstract
The utility model discloses an automobile engine for bent axle doublestage twist reverse bumper shock absorber, including outer hub and interior hub, hub and damping device in the middle of being equipped with between outer hub and the interior hub, damping device including the yielding rubber that absorbs high -frequency vibration and the cavernosum that absorbs low frequency vibration, its yielding rubber is located between hub and the middle hub, the yielding rubber links to each other with the interior hub outside and inboard bonding of middle hub, between hub and the outer hub, the cavernosum was continuous with the middle hub outside and the inboard bonding of outer hub in the middle of its cavernosum was located. The utility model discloses a doublestage twists reverse the bumper shock absorber, owing to adopt doublestage damping device, has increased the damping device of the different characteristics of one -level, the low frequency vibration of the belt gearing system that produces in the time of consequently absorbing the engine operation, and the polyurethane sponge has the sound of inhaling shock -absorbing function, further improves the shock attenuation absorbing effect of engine.
Description
Technical field
The utility model relates to a kind of damping device, relates to a kind of automobile engine crankshaft twin-stage torsion vibration absorber specifically.
Background technique
In the working procedure of motor car engine, when motor reaches a certain rotating speed, uneven owing to operating, along with the mechanical motion of piston, the vibration frequency of motor self and noise will be made to strengthen, not only can bring noise pollution, and go down for a long time, greatly will reduce the working life of bent axle and the performance of motor.At present, the crankshaft torsion vibration absorber that automobile uses, general adopts single-stage rubber shock-absorbing structure, in use, greatly can reduce dither, thus extends bent axle working life, improves the travelling comfort of driving; But the vibration damper of said structure is not effectively controlled to the low-frequency vibration caused by belt drive system and the noise that causes thus, affects overall usability and the working life of motor car engine.
Model utility content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of automobile engine crankshaft twin-stage torsion vibration absorber, effectively to absorb the noise of low-frequency vibration and reduction low-frequency vibration generation.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automobile engine crankshaft twin-stage torsion vibration absorber, includes outer hub and interior hub, is provided with middle hub and damping device between described outer hub and interior hub; Described damping device comprises the yielding rubber of absorbing high-frequency vibration and absorbs the foam body of low-frequency vibration, its yielding rubber is between interior hub and middle hub, yielding rubber is connected with side bonds outside interior hub and in middle hub, its foam body is between middle hub and outer hub, and foam body is connected with side bonds outside middle hub and in outer hub.
Preferably, described foam body is polyurethane sponge.
Further, the inner side of described outer hub is provided with outer hub projection.
Further, the outside of described interior hub is provided with interior hub projection.
Further, described middle hub is provided with middle hub outer lug and middle hub internal projection corresponding to outer hub projection and interior hub projection.
Adopt the model utility of the technical program, its beneficial effect is: twin-stage torsion vibration absorber of the present utility model, owing to adopting dual-stage damping device, add the damping device of one-level different qualities, the low-frequency vibration of the belt drive system produced when therefore can absorb engine running; And polyurethane sponge has sound-absorbing damping function, improve the damping sound-absorbing effect of motor further.In addition, twin-stage torsion vibration absorber of the present utility model, can not only extend the working life of engine crankshaft, and have that structure is simple, fabricating cost is low, long service life and the simple advantage of manufacturing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1, outer hub; 2, interior hub; 3, middle hub; 4, yielding rubber; 5, foam body; 11, outer hub is protruding; 21, interior hub is protruding; 31, middle hub outer lug; 32, middle hub internal projection.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, twin-stage torsion vibration absorber of the present utility model, includes outer hub 1 and interior hub 2, is provided with middle hub 3 and damping device between described outer hub 1 and interior hub 2; Described damping device comprises the yielding rubber 4 of absorbing high-frequency vibration and absorbs the foam body 5 of low-frequency vibration, its yielding rubber 4 is between interior hub 2 and middle hub 3, yielding rubber 4 is connected with side bonds outside interior hub 2 and in middle hub 3, its foam body 5 is between middle hub 3 and outer hub 1, and foam body 5 is connected with side bonds outside middle hub 3 and in outer hub 1.Described foam body 5 is polyurethane sponge.The inner side of described outer hub 1 is provided with outer hub projection 11.The outside of described interior hub 2 is provided with interior hub projection 21.Described middle hub 3 is provided with middle hub outer lug 31 and middle hub internal projection 32 corresponding to outer hub protruding 11 and interior hub projection 21.
Above are only a kind of embodiment of the present utility model, not in order to limit the utility model, all any amendments done within spirit of the present utility model and principle are equivalent to be replaced and improves, and all should be included within protection domain of the present utility model.
