Description
Technical field
The present invention relates to a kind of vehicle driver place drive skill examining device and accessory, particularly the study of a kind of vehicle driver place driving efficiency and test site employed stake bar suspender and 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 " of No. 111 formulation according to the Ministry of Public Security, the important step that the driver is carried out in the 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 crusherbull zone and the spring hanger link mechanism that resets by joint spring.
Learn and the employed spring coupling assembling of test site employed stake bar suspender such as Figure 15, a kind of vehicle driver place driving efficiency shown in Figure 16, the swing of its articulation structure part is by consisting of (referring to Figure 15) with the relative fixed part 6 of internal taper hole with relative tilting member 7 with conehead, and the shaft section after resetting as shown in figure 15; By this figure being carried out the analysis of mechanics and mechanical principle, find the following main deficiency that exists:
1, when use in the 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 (shown in Figure 15) generation when relatively fixed part 6 contact can opposing can cause the external force of slight swing, more very the person is exactly that both are disconnected from each other, the power that causes resisting small sway is the elastic force of remaining tension spring only, the stake bar that is being suspended like this is just easier of breeze animated, and be not easy static, if be used for the used stake bar of suspention driver place driving efficiency examination, finally can have influence on the accuracy to driver's assessment of examination result.
2, when the stake bar amplitude of oscillation is larger, (represent with pivot angle δ 0 in the legend) as shown in figure 16, in the return process, the damping force that is subject to changes not steady, particularly had after the noticeable wear vestige, that is to say the not too uniformly fluctuating acceleration that to change significantly, namely be called traditionally the phenomenon of bump.
3, the tapering of taper fit face and processing technology are closely related, and such as the β 0 among Figure 15, its ultimate value often has different occurrences along with the difference of processing technology; When this value kept clear of ultimate value, because processing technology is different, it is larger that its ratio of damping also differs, and the time that namely freely swings is longer; Can be significantly in reality find: when the pivot angle of β 0 and a bar is all identical, use different processing technologys and assembling process gained coupling assembling out, cause that external force that a bar departs from disappears the time be carved into moment institute's elapsed time length that a bar stops swinging assembly average can obviously differ.
4, because the singularity of modular construction shape, cause processing cutting output larger, energy consumption is large.
