Description
Technical field
The present invention relates to the vehicle testing technique field, particularly, the present invention relates to a kind of vehicle side slipping testing stand for check skid amount size and direction.
Background technology
Skid refers to due to prenex and camber angle mismate, in vehicle traveling process, produce a kind of interaction force between wheel and ground, this acting force is perpendicular to vehicle traveling direction, make tire be in the sliding state of limit rolling, it makes the control stability variation of automobile, increases oil consumption and accelerates the wearing and tearing of tire.
Can at the slide plate that laterally is free to slide, owing to there being above-mentioned acting force, will make slide plate produce lateral slip if allow automobile cross.The sideslip amount of check automobile can judge whether appropriate these two parameters of front wheel toe-in of automobile and flare coordinate.
Vehicle side slipping testing stand is widely used in the various occasions such as automobile safety Performance Detection station.The parts such as the primary structure of vehicle side slipping testing stand comprises stand, slide plate, loosens plate, interlock resetting-mechanism, displacement transducer.The precision of the performance of displacement transducer and interlock resetting-mechanism directly has influence on the accuracy of testing result.
At present, according to the side slid platform formal classification, be divided into structure design of single slab skid check-out console and two plate coordinated type sideslip check-out console, the structure design of single slab skid check-out console can only detect single wheel side sliding amount, can't detect car load.Two plate coordinated type sideslip check-out consoles can detect two wheels simultaneously, the sideslip amount of reflection car load.
Calibration bits displacement sensor just when now on market, all slide type sideslip check-out consoles all are annual equipment calibration can't judge performance and the quality of displacement transducer during routine work, can not guarantee the accuracy of routine testing result.
Now on market during all annual measurement verification of slide type sideslip check-out console, the problem that the most easily occurs is exactly that the synchronism of two slide plates is always overproof, rules require synchronism to be no more than 0.1 millimeter, but great majority are through after the use of a year, have six or seven ten percent all can not satisfy the calibrating requirement, main cause be the performance of displacement transducer change or mechanical component wearing and tearing cause the fit-up gap excessive due to.The quality of displacement transducer performance and mechanical component precision can't be judged during routine work, accuracy and the authority of routine testing result can not be guaranteed.
Summary of the invention
For overcoming existing defective, the present invention proposes a kind of vehicle side slipping testing stand for check skid amount size and direction.
According to an aspect of the present invention, a kind of slide type sideslip check-out console has been proposed, comprise stand, two of left and right slide plate, interlock resetting-mechanism, two loosen plate, cover plate and displacement transducer; It is characterized in that, described sideslip check-out console also comprises four displacement automatic checking devices, and two displacement automatic checking devices are contained in the middle part of stand, two both sides that are arranged on respectively stand.
The present invention has improved the accuracy of testing result, has reduced again staff's labour intensity, can find in time whether the synchronism of slide plate is overproof, has realized the function that equipment automatization checks.
Description of drawings
Fig. 1 is the structural representation of a kind of vehicle side slipping testing stand of embodiment.

As shown in the figure, in order clearly to realize the structure of embodiments of the invention, specific structure and device have been marked in the drawings, but this only needs for signal, be not that intention limits the invention in this ad hoc structure, device and environment, according to specific needs, those of ordinary skill in the art can adjust these devices and environment or revise, and the adjustment of carrying out or modification still are included in the scope of accompanying claim.
Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of vehicle side slipping testing stand for check skid amount size and direction provided by the invention is described in detail.In the following description, a plurality of different aspects of the present invention will be described, yet, for those skilled in the art, can only utilize more of the present invention or entire infrastructure or flow process are implemented the present invention.For the definition of explaining, set forth specific number, configuration and order, but clearly, in the situation that do not have these specific detail can implement the present invention yet.In other cases, in order not obscure the present invention, will no longer be described in detail for some well-known features.
Due to the annual measurement verification of sideslip check-out console once, so can not guarantee the quality of displacement transducer performance and mechanical component precision in routine work, can not guarantee accuracy and the authority of routine testing result.As improvement, the present embodiment has increased the displacement automatic checking device, and it is arranged in stand centre and both sides.
Generally speaking, referring to Fig. 1, slide type sideslip check-out console comprises stand 1, slide plate 2, displacement automatic checking device 3, interlock resetting-mechanism 4, loosens plate 5, cover plate 6 and displacement transducer 7.Interlock resetting-mechanism 4 is contained in the middle part of stand, can freely rotate around central shaft.Slide plate 2 adopts two slide plates in left and right, is placed in the stand front side by roller 15 respectively, links together by interlock resetting-mechanism 4, synchronous inwardly, outwards slippage.
Two displacement automatic checking devices 3 are contained in the middle part of stand 1, and two are arranged on respectively stand both sides.Two are loosened plate 5 corresponding to left and right slide plate 2, are placed in respectively the rear side of stand by roller, independently inside, outwards slippage.Two are loosened plate 5 and do not contact with slide plate 2, contacts with sliding panel during 3 work of displacement automatic checking device, can make slide plate produce constant inside, outside slippage.
Displacement transducer 7 is arranged on the middle part of stand 1, corresponding to displacement automatic checking device 3, is placed in the opposite side of interlock resetting-mechanism 4.With one slide-plate 2 close contacts wherein but without being fixedly connected with, this has just guaranteed the synchronism of displacement transducer and slide plate sideslip by Compress Spring in the sliding bar termination of displacement transducer 7.
