Abstract
The utility model relates to a novel steering wheel dynamic absorber device for vehicles. A mass block (2) is supported by a mounting baseboard (1) through a rubber circular column (3); a small riveting joint (4) is vulcanized in the rubber circular column (3) and used for riveting and fixing the rubber circular column (3) with the mounting baseboard (1); and two limit pipes (5) are arranged on the mounting baseboard (1). The steering wheel dynamic absorber device provided by the utility model requires small mounting space and can ensure that the vibration amplitude of a steering wheel under a corresponding excitation frequency is effectively reduced.
Description
Technical field
The utility model belongs to bearing circle vibration damping field, particularly relates to the less dynamic absorber apparatus in a kind of bearing circle space.
Background technology
The bearing circle dynamic vibration absorber is widely used in translation and the torsion oscillations of bearing circle field to reduce bearing circle.The bearing circle vibration amplitude is greatly to a certain degree then having a strong impact on car load NVH performance, car load traveling comfort variation if can not get control.And can effectively lower its vibration amplitude by the corresponding dynamic vibration absorber of rational Match on bearing circle, the bearing circle idling that at utmost decays shake etc. causes the obviously energy of vibration of bearing circle.
Modal bearing circle dynamic vibration absorber version is by one base plate to be installed by the plantation rubber annulated column mass to be supported, and base plate and mass riveted and fixed will be installed by the little riveted joint of sulfuration in the plantation rubber annulated column, installing has two position-limiting tubes to play motion time limit position on the base plate, prevent to collide other parts in the bearing circle.
Bearing circle produces many vibration peak in vibration processes, Figure 2 shows that the auto-power spectrum curve of bearing circle installation dynamic vibration absorber front and back, X is to produce a greatest peak at the 22.6Hz place, only need a X to be installed and get final product this vibration of effective attenuation to the dynamic vibration absorber of natural frequency 22.6Hz at the bearing circle rational position, former car state acceleration root-mean-square value is 0.417m/s^2, it is 0.155m/s^2 that dynamic vibration absorber post-acceleration mean effective value is installed, according to principle of conservation of energy, the quality of dynamic vibration absorber is big more, the vibrational energy of its absorption is just big more, and effectiveness in vibration suppression is just good more.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel steering wheel dynamic absorber apparatus, with the problem of solution party to disc vibration.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of novel steering wheel dynamic absorber apparatus is provided, by one base plate (1) being installed supports mass (2) by plantation rubber annulated column (3), sulfuration one little riveted joint (4) in the plantation rubber annulated column, be used for and the base plate riveted and fixed is installed, installing on the base plate has two position-limiting tubes (5).
Described installation base plate (1) is welded to form by a body base plate and two position-limiting tubes (5).
Described mass (2) is made up of 20# steel outside face sulfuration one deck rubber.
Described little riveted joint (4) makes by riveted joint base plate (1) is installed, plantation rubber annulated column (3) connects into an integral body with mass (2).
Description of drawings
Fig. 1 is the utility model sectional structure scheme drawing;
Fig. 2 is the auto-power spectrum curve that bearing circle is installed the dynamic vibration absorber front and back;
Fig. 3 is a bearing circle dynamic vibration absorber example of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of novel steering wheel dynamic absorber apparatus, by one base plate (1) being installed supports mass (2) by plantation rubber annulated column (3), sulfuration one little riveted joint (4) in the plantation rubber annulated column is used for and the base plate riveted and fixed is installed, on the installation base plate two position-limiting tubes (5) is arranged.
For reaching better effectiveness in vibration suppression, in bearing circle of this example two dynamic vibration absorbers are installed, as shown in Figure 3, and verification experimental verification, two dynamic vibration absorber effects are better than one.
Claims (4)
1. novel automobile bearing circle dynamic absorber apparatus, comprise mass (2) and plantation rubber annulated column (3) composition one mass-spring system, it is characterized in that, described mass (2) is installed base plate (1) by one and is supported by plantation rubber annulated column (3), sulfuration one little riveted joint (4) in the described plantation rubber annulated column (3), be used for and base plate (1) riveted and fixed is installed, installing on the base plate (1) has two position-limiting tubes (5).
