Description
Technical field
The utility model relates to the absorbing technology of automobile suspension system, is specifically related to the adjustable absorbing technology to leaf spring.
Background technique
What require car comfort along with the fast development of automobile industry and user improves constantly, and auto NVH control technique seems more and more important.Automobile suspension system is in car running process, it mainly plays the force and moment transmitted between vehicle frame and vehicle body, alleviate the impulsive load produced because of Uneven road, and alleviate the vibration of vehicle body, therefore the magnitude of vibrations of suspension system to ensureing the smoothness of automobile running, the travelling comfort that personnel taken advantage of by frame, the stability carried cargo has positive effect.
Automobile leaf spring is most widely used a kind of elastic element in automotive suspension, it is the elastic beam of the approximately equi-strength combined by some wide alloy spring sheets, if control magnitude of vibrations by Optimal Spring sheet, change larger to leaf spring, and difficulty is larger.
Therefore, be necessary to provide a kind of structure of automobile leaf spring being carried out to absorbing, reduce transmission system and the magnitude of vibrations of Leaf Spring Suspension System at a certain frequency place.
Summary of the invention
Of the present utility modelly provide a kind of adjustable bump leveller, to be arranged on magnitude of vibrations leaf spring improving suspension system.
The technical solution of the utility model is as follows:
The utility model provides a kind of adjustable bump leveller be arranged on automobile leaf spring, and it comprises mass block, block rubber and mounting base; Described block rubber is arranged on leaf spring by mounting base; Described mass block is configured with at least 2 pieces, is removably mounted on block rubber.By this bump leveller is installed on automobile leaf spring, by the configuration of mass block, and the buffering of block rubber, effectively can control the magnitude of vibrations of suspension system at a certain frequency place.
Further, the conveniently adjustment of quality, described mass block is not preferably designed as quality not etc., so that configure different quality as required, reaches best shock attenuation result.
Further, from constitutionally stable angle, described block rubber is provided with quality mounting bracket, and described mounting base is positioned at the below of block rubber, three in one sulfidization molding, and mass block is installed on block rubber by quality mounting bracket.
Further, the conveniently installation of mass block, from threaded shank on described quality mounting bracket, mass block is through on threaded stem, tightens fixing by the mass block tightening nut of threaded stem upper end.
Further, described mounting base is installed on leaf spring by base mounting support, particularly, described mounting base is positioned at above leaf spring, described base mounting support surrounds leaf spring from below, mounting base and base mounting support clamp leaf spring up and down, and two ends realize being fastenedly connected by base fixing bolt and base set screw nut.Can make that mounting base is more convenient to be installed on leaf spring securely like this,
Based on above adjustable bump leveller, the utility model provides a kind of automobile leaf spring with adjustable vibration absorbing structure further, and it comprises the leaf spring combined by some spring sheets, and leaf spring is installed the adjustable bump leveller of said structure.
The beneficial effects of the utility model are: the adjustable bump leveller of this leaf spring effectively can control the magnitude of vibrations of suspension system at a certain frequency place, therefore, effectively can ensure that the smoothness of automobile running, the travelling comfort of driver and passenger, the stability that carries cargo have positive effect, improve vehicle NVH performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of adjustable bump leveller
Fig. 2 is the structural representation of the automobile leaf spring with adjustable vibration absorbing structure.
In figure, 1-tightening nut, 2-mass block, 3-quality mounting bracket, 4-block rubber, 5-mounting base, 6-base fixing bolt, 7-base set screw nut, 8-base mounting support, 9-leaf spring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of adjustable bump leveller, comprises mass block tightening nut 1, mass block 2, quality mounting bracket 3, block rubber 4, mounting base 5, base fixing bolt 6, base set screw nut 7 and base mounting support 8.
Block rubber 4 is provided with quality mounting bracket 3, under have mounting base 5, three in one sulfidization molding, mounting base thickness 1mm, base mounting support thickness 2mm.Described block rubber size immobilizes, and namely the rigidity of system is fixed, and by increase and decrease variable-quality block, regulates required frequency.
It is equal that mass block 2 can arrange quality, but the polylith preferably do not waited, as shown in the figure 3 pieces, through the threaded stem that quality mounting bracket 3 carries, tighten fixing by the mass block tightening nut 1 of threaded stem upper end.According to
Mounting base 5 is installed on leaf spring by base mounting support 8, mounting base 5 is positioned at above leaf spring, base mounting support 5 surrounds leaf spring from below, mounting base and base mounting support clamp leaf spring up and down, and two ends realize being fastenedly connected by base fixing bolt 6 and base set screw nut 7.
See Fig. 2, the mounting type of adjustable bump leveller on leaf spring is as follows:
First, base mounting support 8 is coordinated with leaf spring 9 from below.
Mounting base 5 is put on leaf spring 9, aligns with base mounting support 8 bolt hole, then load onto fixing bolt 6 and nut 7, with hand fastening nut a little, make it temporarily be fixed on leaf spring 9, do not produce and rock.
Then, will band circular vias variable-quality block 2 be contained on quality mounting bracket 8, then with hand a little threaded together bar upper end mass block tightening nut 1 tighten variable-quality block 2, make it temporarily be fixed on quality mounting bracket 8, do not produce and rock.
Finally, according to increase and decrease variable-quality block 2, regulate required frequency, then load onto mass block tightening nut 1, to screw on each nut with spanner, then use torque spanner fastening nut, its value is 100 Nmm.
The frequency of this dynamic vibration absorber can be adjusted to three kinds of different frequencies, improves the vibration under the corresponding frequencies that transmission system and Leaf Spring Suspension cause, improves vehicle NVH performance.
