Abstract
The utility model discloses an automobile flexible hinge bellows. The heights of a first wave and a second wave at both ends are lower than the heights of other waves. The height of the first wave is lowest, the height of the second wave is higher than the height of the first wave, a third wave and the following waves are normal waves, and the heights of the normal waves are the same. A vibration source is sent to the bellows through a steel tube, wherein the height of the first wave is lowest; compared with the other waves, the rigidity of the first wave is highest; the height of the second wave is the secondary; the heights of the third wave and the following waves are normal heights, and the rigidity thereof is smaller. As a first advancing wave and a second advancing realize the transition from large rigidity to small rigidity, the two waves are difficult to produce fatigue failure, and the service life of the bellows is greatly prolonged.
Description
Technical field
The utility model belongs to the auto parts machinery field, is specifically related to the bellows in a kind of automobile flexible joint.
Background technique
Automobile flexible joint is to connect motor and vent systems, plays the heavy connection of absorbing, damping effect.Use automobile flexible joint can increase personnel's travelling comfort by bus, effectively improve the working environment of purification plant in the vent systems, protection is arranged and prolong air cleaner, the motor effect in working life.
Bellows is a most important part in the automobile flexible joint assembly, and it is a thin-walled elastic element of axisymmetric band ripple.The characteristics of corrugation geometry make bellows under the effect of pressure, axial force, transverse force and moment of flexure, can produce very big displacement, change the shape and size of element, are returned to original state behind the load removal again.The elasticity of its thin-walled material of utilizing bellows realizes connecting, the function of conversion, absorbing, vibration damping and compensate for displacement.
The antivibration viability of the bellows of automobile flexible joint itself is directly determining working life of automobile flexible joint.During automobile running, jolting of the high speed operation of motor and road surface is in the continuous vibration vent systems, and automobile flexible joint will absorb the vibration of vent systems, each ripple of bellows all will play the effect that absorbs vibration uniformly, and automobile flexible joint just can have long working life like this.The waveform of bellows (geometrical shape) is determining the antivibration viability of bellows.See Fig. 1, the geometrical shape of existing each ripple of bellows all is the same, and promptly the wave height of each ripple is all identical, and then the rigidity of each ripple is also all identical, and each wave-wave height is all identical after reaching as first ripple 1, second ripple 2, the 3rd ripple 3 among Fig. 1.The factor of connection is not considered in this design, bellows itself is the less flexible part of rigidity, but what be connected with its two ends is the steel pipe that is connected with vent systems with motor, just there are a bigger hidden danger in rigid steel pipes and bellows joint, vibration all is to be delivered on the bellows by rigid steel pipes in use, first ripple 1 that is connected with steel pipe and second ripple, 2 stress are just bigger, and these two ripples are easy to produce fatigue failure, make the too early inefficacy of whole automobile flexible joint.
The content of model utility
Above-mentioned shortcoming at the bellows that has automobile flexible joint now, the claimant has carried out improving research, another kind of bellows is provided, change the waveform of bellows two ends first ripple and second ripple, there is one in use between steel pipe and the bellows firmly to soft transition, the working life of the effectively raising bellows of energy.
The technical solution of the utility model is as follows:
A kind of bellows of automobile flexible joint, first ripple at its two ends and the wave height of second other each ripples of Bob are little, and the wave height minimum of first ripple, and the wave height of second ripple is bigger than the wave height of first ripple, and the 3rd ripple is later on an ordinary wave, and the ordinary wave wave height is identical.
Useful technique effect of the present utility model is:
Vibration source is passed on the bellows by steel pipe, the wave height minimum of first ripple, it is the highest to compare its rigidity of other ripple, second ripple secondly, the 3rd ripple is normal wave height later on, and its rigidity is less, realizes the descending transition of rigidity by first, second two pre-prewaves, make these two ripples be not easy to produce fatigue failure, just can have bigger lifting the working life of bellows.
Description of drawings
Fig. 1 is the cross-sectional schematic of the bellows of existing automobile flexible joint.
Fig. 2 is a cross-sectional schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 2, first ripple 1 and second ripple 2 at the utility model two ends are littler than the wave height of other each ripples, and the wave height minimum of first ripple 1, and the wave height of second ripple 2 is bigger than the wave height of first ripple 1, and the 3rd ripple 3 is an ordinary wave later, and the ordinary wave wave height is identical.
During manufacturing, by the waveform length of run of first ripple first pitch length of forming die as a whole, the waveform length of run of second ripple is second pitch length of forming die as a whole, and the waveform length of run of the 3rd ripple is the 3rd pitch length of forming die as a whole, by that analogy.Behind the whole shaped by fluid pressure of welded tube, just have two pre-prewaves, the bellows of this spline structure will improve a lot working life.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that those skilled in the art under the prerequisite that does not break away from spirit of the present utility model and design, can make other improvement and variation.
