Behind the cylinder carrying wheel on the existing drum reaction brake test bench, in the process of drum rotating, wheel easily departs from the simulated roadway that cylinder consists of, and needs operating personnel that wheel is adjusted, this is just so that checkout procedure becomes loaded down with trivial details, and has affected checkability.
The utility model content
This practical purpose is to overcome the deficiencies in the prior art, provides a kind of and can carry out spacing to the wheel of automobile and guiding, can avoid wheel to depart from simulated roadway, and then improves the Vehicles Brake Test Bench that can lead to wheel of checkability.
The purpose of this utility model is achieved through the following technical solutions: the Vehicles Brake Test Bench that can lead to wheel, comprise frame, two groups of brake inspection devices about described frame is provided with, two groups of brake inspection devices include head roll and with the driven cylinder of the parallel placement of head roll, driven cylinder two ends respectively with the head roll justify align, be provided with supporting station between described head roll and the driven cylinder, be provided with two stop means on the supporting station; Described stop means comprises base, backstay and gear wheel, and described backstay is connected in the base upper surface, and backstay upper end is arranged with annular limiting stand, and described gear wheel is set on the backstay between base and the upper annular limiting stand.
Described gear wheel is comprised of a cylinder and the blank cover that is connected in this cylinder upper end, the blank cover central part of described gear wheel is provided with the circular perforations that runs through its upper and lower end face, the internal diameter of this circular perforations is less than upper annular limiting stand outer shroud circular diameter, and described backstay passes the circular perforations of blank cover.
Be arranged with the lower annular stop platform of supporting gear wheel on the described backstay, the blank cover lower surface of gear wheel contacts with the upper surface of lower annular stop platform, and the outer shroud circular diameter of described lower annular stop platform is greater than the circular perforations internal diameter of blank cover.
Contact with base for fear of wheel, described base consists of rectangular shape, and the barrel bore of described gear wheel is greater than the width of base upper surface.
Two positions of stop means on supporting station in every group of brake inspection device are respectively near the two ends of head roll.Because of driven cylinder two ends in every group of brake inspection device respectively with the head roll justify align, when two stop means are arranged on the supporting station also respectively near driven cylinder two ends.
Compared with prior art, the utlity model has following beneficial effect: when (1) the utility model is used, the left and right wheels of automobile is placed on respectively on the simulated roadway that head roll and driven cylinder consist of in two brake inspection devices, when automotive wheel moves to the simulated roadway two ends, this moment wheel can with the sidewall contact of gear wheel, gear wheel rotates around backstay under the induced effect of wheel, and gear wheel can change the direction of motion of wheel when rotating, and then avoid wheel to depart from simulated roadway, the utility model is regulated and control the direction of motion of wheel by stop means when wheel touching stop means, easy to operate, and do not need the operator to get involved the adjustment wheel position, can improve checkability.
(2) the utility model gear wheel can rotate around backstay, and under the rotary action of gear wheel, rigid friction reduces between gear wheel and the wheel, so can avoid gear wheel to carry out spacing to wheel and during guiding gear wheel or wheel damage.
(3) carry out spacingly by upper annular limiting platform and lower annular stop platform to the position that moves up and down of gear wheel in the utility model, break away from backstay in the time of avoiding gear wheel to rotate, this has guaranteed the stable of the utility model structure.
