As shown in Figure 3 and Figure 4, feed screw 152a and 152b extend upward in front and back and engage respectively feed nut 153a and 153b.In addition, feed screw 152a and 152b by reducing gear 155a and 155b, are connected with 151b with servomotor 151a respectively separately.Therefore, when driving servomotor 151a and 151b, feed screw 152a and 152b rotate, and feed nut 153a and 153b advance and retreat along feed screw.Because feed nut 153a and 153b are separately fixed in bearing unit 170 and 160, therefore along with the advance and retreat of feed nut 153a and 153b, bearing unit 170 and 160 is also advanced and retreat along feed screw.
,, the bearing unit 170 in left side is advanced herein towards the working direction of automobile C, and make right-hand axis bearing unit 160 only retreat identical apart from the time, then anterior pulley 111 is that the center clockwise rotates with axial central authorities when observing.Be positioned at left-hand axis bearing unit 170 under the state in right-hand axis bearing unit 160 the place aheads, when drive wheels W or power absorption device 120 advanced the top 116a of steel band, steel band 116 moved to the right.
In addition, if towards the working direction of automobile C, the bearing unit 170 in left side is retreated, and make the right-hand axis bearing unit 160 identical distance of only advancing, then anterior pulley 111 is that the center rotates counterclockwise with axial central authorities when observing.Be positioned at right-hand axis bearing unit 160 under the state in left-hand axis bearing unit 170 the place aheads, when drive wheels W or power absorption device 120 advanced the top 116a of steel band, steel band 116 moved to the left.
Like this, in the present embodiment, rotate as described above, can make steel band 116 on Width, move the offset that to correct the Width of steel band 116 by make anterior pulley 111 with the band straightening mechanism.In addition, in the present embodiment, it is identical that bearing unit 170 and 160 translational speed are controlled as, and anterior pulley 111 rotates around the vertical axes by its axial central point (that is, with as the vertical axis of the top 116a of simulated roadway) as described later.
The flat rubber belting mechanism 100 of present embodiment possess the pick-up unit 190 that crawls that crawls that is used to detect steel band 116 (Fig. 3, Fig. 4).Detailed description to the pick-up unit 190 that crawls is narrated in the back.The controller 2 of driving tester 1 (Fig. 3,4) is according to the testing result of the pick-up unit 190 that crawls, and control band apparatus for correcting 150 is to correct crawling of steel band 116.Controller 2 can transmit control signal to band apparatus for correcting 150 in 1 millisecond that detects after crawling.And then, in the present embodiment, by adopting the answer speed that constitutes by servomotor and feed screw mechanism actuator faster, can with the interior extremely short response time anterior pulley 111 be rotated to detect after crawling 5 milliseconds.Therefore, the pick-up unit 190 that crawls can be corrected crawling of steel band 116 after detecting the crawling of steel band 116 immediately, even carry out still can correcting crawling of steel band 116 under the situation of running test with the high speed of speed per hour 100～hundreds of km.And then, since detect crawl after immediately, promptly extends in the part that causes steel band 116 by crawling to correct under the less state and crawl, so it is less to be applied to the load of steel band 116, compare with driving tester of the prior art, can prolong the life-span of steel band 116.
Below, the structure of the testing agency 190 of crawling is described.Fig. 5 is the stereographic map of pick-up unit 190 of crawling.As shown in Figure 5, near the 116b of the end of steel band 116, form slit 116c.The pick-up unit 190 that crawls possesses illuminating part 191 and the light accepting part 192 that disposes in the mode that clips this slit 116c.The 1st sensitive surface 192a and the 2nd sensitive surface 192b that are provided with in the transverse direction alignment arrangements at light accepting part 192.Light accepting part 192 can be distinguished independent instrumentation to the light quantity of the light of the 1st sensitive surface 192a incident with to the light quantity of the light of the 2nd sensitive surface 192b incident.
From illuminating part 191 send and light by slit 116c to the 1st sensitive surface 192a or the 2nd sensitive surface 192b incident of light accepting part 192.In the present embodiment, under the state that steel band 116 does not have to crawl (solid line among the figure is represented the end of the steel band 116 of this moment), adjust, so that and about equally by the detected light quantity of the 2nd sensitive surface 192b by the detected light quantity of the 1st sensitive surface 192a.
From the state that does not have at steel band 116 to crawl, steel band 116 begins to crawl and to the 1st sensitive surface 192a side, when moving (end that the dotted line among the figure is represented the steel band 116 of this moment) at Width, a part that then is incident to the light of the 2nd sensitive surface 192b when not having to crawl is blocked by steel band 116, can not be incident to the 2nd sensitive surface 192b.Consequently, by the detected light quantity of the 2nd sensitive surface 192b less than by the detected light quantity of the 1st sensitive surface 192a.
On the other hand, if state from not having at steel band 116 to crawl, steel band 116 crawl and to the 2nd sensitive surface 192b side, move (end of steel band 116 that the dot-and-dash line among the figure is represented this moment) at transverse direction, a part that then is incident to the light of the 1st sensitive surface 192a when not having to crawl is blocked by steel band 116, can not be incident to the 1st sensitive surface 192a.Consequently, by the detected light quantity of the 1st sensitive surface 192a less than by the detected light quantity of the 2nd sensitive surface 192b.
Like this, in the present embodiment, by the detected light quantity of the 1st sensitive surface 192a with by the detected light quantity of the 2nd sensitive surface 192b, can detect steel band 116 and whether take place to crawling of moving of which direction by relatively.
As mentioned above, in the driving tester 1 of present embodiment, crawling of straightening mechanism 150 of band corrected.In addition, driving tester 1 also possesses the band guide mechanism 180 that crawls that is used to prevent steel band 116 on the basis of above-mentioned band straightening mechanism 150.As shown in Figure 3 and Figure 4, band guide mechanism 180 possesses 4 groups of guiding rollers 181 that are supported, and this guiding roller 181 can rotate freely.For guiding roller 181, its turning axle disposes towards vertical direction, and, by the spring of not representing among the figure, at transverse direction this guiding roller 181 is exerted pressure towards the end of steel band 116.
The stereographic map of expression guiding roller 181 in Fig. 6.As shown in Figure 6, the periphery at guiding roller 181 is formed with the groove 181a that extends at circumferencial direction.This groove 181a is a bit larger tham steel band 116 thickness with groove width mode forms, so that among the end 116b embedded groove 181a of steel band 116.
Like this, in the present embodiment, because steel band 116 is exerted pressure by the two ends guide pick-up roll 181 from Width, even therefore apply the power of Width to steel band 116, crawling of steel band 116 also is difficult to take place.And then as previously mentioned, even steel band 116 crawls a little, this crawls also can (Fig. 3 Fig. 4) be corrected rapidly by band straightening mechanism 150.
The bearing unit 170 and 160 that axle 111a is supported, so that the mode that axle 111a freely rotates around vertical axes in the position of each bearing unit 170 and 160 supports axle 111a, so that the band straightening mechanism 150 by embodiments of the present invention make anterior pulley 111 the axle 111a when vertical axes is rotated, can not apply bending load to axle 111a.Below, the supporting structure of axle 111a is described.
