Description
Technical field
The present invention relates to a kind of vehicle driver place drive skill examining device and accessory, the stake bar suspender that particularly study of a kind of vehicle driver place driving efficiency and test site use and the rigid hanger that this suspender is installed.
Background technology
Make the requirement of the industry standard GA/T554-2008 " field driving skill examination system for automotive drivers " formulating for No. 111 according to the Ministry of Public Security, the important step that driver is carried out in driving efficiency examination is will carry out stake to examine; Mostly the suspender that existing driver pile examination examination hall is used is to realize by joint spring the spring hanger link mechanism of crusherbull zone and reset.
The spring coupling assembling that the stake bar suspender that a kind of vehicle driver place driving efficiency study as shown in Figure 15, Figure 16 and test site are used is used, the swing part of its articulation structure forms (referring to Figure 15) by the relative fixed part 6 with internal taper hole with the relative tilting member 7 with conehead, and the shaft section after reset as shown in figure 15; By this figure being carried out to the analysis of mechanics and mechanical principle, find the following main deficiency existing:
1, while application on examination hall, tension spring L is affected by the extraneous factors such as examination vehicle easily and produces rigidity deformation, thereby easily cause pulling force prestress to be reduced to deficiency so that relatively tilting member 7 when relatively fixed part 6 contacts (shown in Figure 15) produce the external force that can opposing can cause slight swing, more very person is exactly that both are disconnected from each other, cause resisting the only elastic force of remaining tension spring of power of small sway, the stake bar being suspended is like this just more easily by breeze animated, and be not easy static, if for suspending driver place driving efficiency examination stake bar used in midair, finally can have influence on the accuracy to driver's assessment of examination result.
2, in the time that the stake bar amplitude of oscillation is larger, (in legend, represent with pivot angle δ 0) as shown in figure 16, in return process, the damping force being subject to changes not steady, after particularly having had noticeable wear vestige, that is to say the fluctuating acceleration not too uniformly that can change significantly, be called traditionally the phenomenon of shock.
3, the tapering of taper fit face and processing technology are closely related, and as the β 0 in Figure 15, its ultimate value, along with the difference of processing technology, often has different occurrences; When this value is not when the ultimate value, because of processing technology difference, it is larger that its ratio of damping also differs, and the time freely swinging is longer; Can be significantly in reality find: in the time that the pivot angle of β 0 and stake bar is all identical, the coupling assembling that uses different processing technologys and assembling process to draw, cause that external force that a bar departs from disappears time be carved into moment institute's elapsed time length that a bar stops swinging assembly average can obviously differ.
4, due to the singularity of modular construction shape, cause processing cutting output larger, energy consumption is large.
Summary of the invention
The object of this invention is to provide a kind of rigid hanger hanger and anti-swing rigid hanger that allows swing and passive reset, this hanger is rational in infrastructure, there is larger ratio of damping, when a suspention stake bar can be avoided the generation of impingement phenomenon, hour have enough anti-swing power at pivot angle δ when suspention stake bar in the time that pivot angle δ is larger, and processing and fabricating is easy, the problems referred to above that exist to solve prior art.
