Abstract
The utility model provides a kind of vibration damping flange assembly, comprise spline flange, also be provided with vibration isolation rubber circle and counterweight ring, installed by vibration isolation rubber circle interference fit between spline flange and counterweight ring, the utility model has the advantages that: structure is simple, by increasing the counterweight ring different from its rotary inertia on spline flange, disturbance is increased when the vibration of spline flange, thus change vibration frequency and the amplitude of whole system, thus avoid producing resonance phenomenon, realize the reduction of main gearbox assembly noise.
Description
Technical field
The utility model relates to component in automobile driving axis, relates to main gearbox assembly flange in driving axis specifically.
Background technique
Along with the development of China Automobile Industry, vehicle manufacturers and terminal use the requirement of client to the assembly noise of automobile progressively to improve.Wherein noise problem is more insoluble is the noise of main reducing gear in ransaxle.Because the noise of main gearbox assembly is except relating to component accuracy of manufacturing, assembly precision, the foeign element such as vibration, unbalancing value passed over from motor, gearbox, transmission shaft, vehicle frame also can cause obvious impact.By market research, get rid of outside accuracy of manufacturing and assembly precision, the ratio that the impact of foeign element causes main reducing gear of drive axle assembly noise to exceed standard is very large.
Summary of the invention
The technical problem that the utility model solves is that in existing ransaxle, main reducing gear is due to external many factors, and that avoids produces resonance phenomenon in transmission system, thus produces the noise that can not accept.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: vibration damping flange assembly, comprises spline flange, is also provided with vibration isolation rubber circle and counterweight ring, is installed between spline flange and counterweight ring by vibration isolation rubber circle interference fit.When vibration damping flange starts to rotate, due to spline flange be non-rigidly being connected of being realized by yielding rubber circle between counterweight ring, and the boundary dimension of two component, to vary in weight, the rotary inertia produced is also different, between two component, namely vibration isolation rubber circle can produce a damping function, to motive force delivery system meeting product negative energize, changes vibration frequency and the amplitude of whole system, thus avoid producing resonance phenomenon, realize the reduction of main gearbox assembly noise.
The utility model has the advantages that: structure is simple, by increasing the counterweight ring different from its rotary inertia on spline flange, disturbance is increased when the vibration of spline flange, thus change vibration frequency and the amplitude of whole system, thus avoid producing resonance phenomenon, realize the reduction of main gearbox assembly noise.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model when installing and using.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1-2, vibration damping flange assembly 1 to be arranged in ransaxle bridge in main gearbox assembly foremost, is connected, spline flange 2 end face is processed with the hole be connected with transmission shaft construction bolt by spline with driving gear in main reducing gear; When car load travels, power passes to main reducing gear of drive axle assembly by transmission shaft and drives car load to travel.In power transmission process, owing to affecting by the gap between the unbalancing value of transmission shaft itself, each component, whole transmission system can produce vibration, and the frequency of vibration and amplitude have notable difference under different travelling speeds.When the vibration frequency of each component is close, whole system can produce resonance, and now amplitude obviously increases, and noise also obviously rises simultaneously.
The utility model comprises spline flange 2, vibration isolation rubber circle 3, counterweight ring 4, is mounted to vibration damping flange assembly 1 between spline flange 2 and counterweight ring 4 by vibration isolation rubber circle 3 interference fit.
Vibration damping flange assembly 1 owing to having vibration isolation rubber circle 3 between spline flange 2 and counterweight ring 4, rubber ring itself has damping function, when vibration damping flange assembly rotates, owing to being connected for non-rigid between spline flange 2 with counterweight ring 4, and the boundary dimension of two component, vary in weight, the rotary inertia produced is also different, between two component, namely vibration isolation rubber circle can produce a damping function, a negative energize can be produced to motive force delivery system, change vibration frequency and the amplitude of whole system, thus avoid producing resonance phenomenon, realize the reduction of main gearbox assembly noise.
