The anterior pulley 111 of flat rubber belting mechanism 100 is arranged on the upper frame portion 132 of the framework 130 of flat rubber belting mechanism 100 by bearing unit 170 (Fig. 3) and 160 (Fig. 4).Equally, the rear portion pulley 112 of flat rubber belting mechanism 100 is arranged on the upper frame 132 of the framework 130 of flat rubber belting mechanism 100 by bearing 181 (Fig. 3) and 182 (Fig. 4).In addition, in flat rubber belting mechanism 100, be provided with multiple help rolls 115 along the inner peripheral surface of top (for loading the par of the wheel W) 116a of steel band 116.As shown in Figure 3, for multiple help rolls 115, make its axially parallel in anterior pulley 111 and rear portion pulley 112 axially, on the moving direction of the top of steel band 116a, equally spaced arrange.Automobile C is being disposed under the state in flat rubber belting mechanism 100, and wheel W is configured on help roll 115 by steel band 116, and supports automobile C by auxiliary wheel 115.Because the driving tester 1 of present embodiment is like this not only by the tension force working on the steel band 116 being set up on anterior pulley 111 and rear portion pulley 112, also support automobile C by help roll 115, therefore can carry out the running test of large weight automobile.
Below, power absorption device 120 is described.As shown in Figure 3, power absorption device 120 possesses: the servomotor 121 that is fixed on upper frame portion 132, be arranged on the drive pulley 122 of the output shaft of servomotor 121, with the follow-up pulley 123 of the coaxial setting of rear portion pulley 112 and be erected at drive pulley 122 and follow-up pulley 123 on power absorption with endless belt 124.While driving servomotor 121, the torque of its output shaft is passed to rear portion pulley 112 by drive pulley 122, power absorption with endless belt 124 and follow-up pulley 123.Apply and advance or the power of direction of retreat to the top 116a of steel band 116 by the torque that is passed to rear portion pulley 112.This power is passed to wheel W from steel band 116.
In the situation that wheel W is driving wheel, the power providing from power absorption plant 120 becomes the load that is applied to automobile C.; in the time that wheel W rotates to the direction that automobile C is advanced (rotating counterclockwise in Fig. 3); power absorption device 120 provides opposite direction load to wheel W, thereby can apply to automobile C the power of the reacting force equivalence of bearing from actual road surface in the time that automobile C accelerates with wheel W.On the other hand, wheel W to automobile C is advanced direction rotation time, equidirectional load is applied to wheel W by power absorption device 120, thereby the power of the reacting force equivalence of bearing from actual road surface in the time that automobile C slows down with wheel W can be provided to automobile C.
In addition, in the situation that wheel W is engaged wheel, can wheel W be rotated by power absorption device 120.
In addition, power absorption device 120 can be by wheel W being applied as made wheel W to the load the direction rotation identical or contrary with the sense of rotation of wheel W, provides the load equal with being applied to the load of travelling on the automobile of descending or upward slope to automobile C.
The flat rubber belting mechanism 100 of present embodiment is constituted as the acceleration or deceleration of can instrumentation following automobile C and is applied to the size of the load automobile C from the steel band 116 as simulated roadway.Owing to can carrying out such instrumentation, therefore can be between the upper frame portion 132 of flat rubber belting mechanism 100 and lower frame portion 131, sandwich multiple 3 axial compression electric devices 142.3 axial compression electric devices 142 carry out instrumentation using the load-carrying being applied to from automobile C flat rubber belting mechanism 100 as orthogonal 3 component force.Be the load-carrying equating with the reacting force that is applied to the load-carrying automobile C from flat rubber belting mechanism 100 owing to being applied to the load-carrying of flat rubber belting mechanism 100 from automobile C, therefore can be according to the measuring load result of 3 axial compression electric devices 142, instrumentation is applied to the load-carrying of automobile C from road surface.
During using driving tester 1 to carry out the running test of automobile C, sometimes apply the laterally power of (Width of automobile C) from wheel W to steel band 116 by bearing circle operation etc.When such transverse force is applied to steel band 116, the possibility that exists steel band 116 to crawl to lateral excursion from front and rear pulley 111,112.The driving tester 1 of present embodiment possesses the band straightening mechanism 150 crawling for correcting steel band 116.Below the details with straightening mechanism 150 of present embodiment is described.
As shown in Figure 3 and Figure 4, band straightening mechanism 150 possess a pair of servomotor 151a and and 151b, a pair of reducing gear 155a and 155b, a pair of feed screw 152a and 152b, and a pair of feed nut 153a and 153b.
As shown in Figure 3, towards the working direction of automobile C, at left-hand axis bearing unit 170, each 2 slide blocks (runner block) 154a that fixes up and down, these slide blocks engage with the 133a of pair of guide rails up and down extending in automobile C travel direction respectively.Therefore, bearing unit 170 can be guided by guide rail 133a and move up in front and back.In addition as shown in Figure 4, towards the working direction of automobile C, at right-hand axis bearing unit 160, respectively up and down fix 2 slide block 154b, these slide block and engage with the 133b of pair of guide rails up and down extending in automobile C travel direction respectively.Therefore, bearing unit 160 can be guided by guide rail 133b and move up in front and back.
As shown in Figure 3 and Figure 4, feed screw 152a and 152b extend and engage and have feed nut 153a and 153b respectively on fore-and-aft direction.In addition, feed screw 152a and 152b by reducing gear 155a and 155b, are connected with servomotor 151a and 151b respectively separately.Therefore, while 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.
, towards the working direction of automobile C, the bearing unit 170 in left side is advanced herein, and while making right-hand axis bearing unit 160 only retreat identical distance, anterior pulley 111 clockwise rotates centered by axial central authorities when observing.Be positioned at left-hand axis bearing unit 170 under the state in right-hand axis bearing unit 160 fronts, while driving wheel W or power absorption device 120 that the top 116a of steel band is advanced, steel band 116 moves 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, anterior pulley 111 rotates counterclockwise centered by axial central authorities when observing.Be positioned at right-hand axis bearing unit 160 under the state in left-hand axis bearing unit 170 fronts, while driving wheel W or power absorption device 120 that the top 116a of steel band is advanced, steel band 116 moves to the left.
Like this, in the present embodiment, by make anterior pulley 111 rotate as described above with band straightening mechanism, can make steel band 116 move on Width, can correct the position skew of the Width of steel band 116.In addition, in the present embodiment, the translational speed of bearing unit 170 and 160 is controlled as identical, and anterior pulley 111 as described later, rotate around the vertical axes by its axial central point (, the axis vertical with top 116a as simulated roadway).
The flat rubber belting mechanism 100 of present embodiment possesses the pick-up unit 190 (Fig. 3, Fig. 4) that crawls crawling for detection of steel band 116.Detailed description to the pick-up unit 190 that crawls is narrated in the back.The controller 2 (Fig. 3,4) of driving tester 1, according to the testing result of the pick-up unit 190 that crawls, is controlled band apparatus for correcting 150, 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 actuator faster being formed by servomotor and feed screw mechanism, can with the interior extremely short response time, anterior pulley 111 be rotated with 5 milliseconds of detecting after crawling.Therefore, the pick-up unit 190 that crawls can be corrected crawling of steel band 116 immediately after detecting the crawling of steel band 116, even carry out in the situation of running test with the high speed of speed per hour 100～hundreds of km, still can correct crawling of steel band 116.And then, due to detect crawl after immediately, extend under less state and correct and crawl in the part that causes steel band 116 by crawling, the load that is therefore applied to steel band 116 is less, compared with driving tester of the prior art, can extend 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 to clip illuminating part 191 and the light accepting part 192 that the mode of this slit 116c configures.The 1st sensitive surface 192a and the 2nd sensitive surface 192b that are provided with in 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.
Send and pass through the light of slit 116c to the 1st sensitive surface 192a or the 2nd sensitive surface 192b incident of light accepting part 192 from illuminating part 191.In the present embodiment, under the state that does not have to crawl at steel band 116 (solid line in figure represents the end of steel band 116 now), adjust, so that the light quantity being detected by the 1st sensitive surface 192a and the light quantity that detected by the 2nd sensitive surface 192b are roughly equal.
From not having the state crawling to start at steel band 116, steel band 116 starts to crawl and to the 1st sensitive surface 192a side, move (end that the dotted line in figure represents steel band 116 now) during at Width, a part that is incident to the light of the 2nd sensitive surface 192b in the time not having to crawl is blocked by steel band 116, can not be incident to the 2nd sensitive surface 192b.Consequently, the light quantity being detected by the 2nd sensitive surface 192b is less than the light quantity being detected by the 1st sensitive surface 192a.
On the other hand, if from not having the state crawling to start at steel band 116, steel band 116 crawl and to the 2nd sensitive surface 192b side, move (end that the dot-and-dash line in figure represents steel band 116 now) at transverse direction, a part that is incident to the light of the 1st sensitive surface 192a in the time not having to crawl is blocked by steel band 116, can not be incident to the 1st sensitive surface 192a.Consequently, the light quantity being detected by the 1st sensitive surface 192a is less than the light quantity being detected by the 2nd sensitive surface 192b.
Like this, in the present embodiment, by the light quantity relatively being detected by the 1st sensitive surface 192a and the light quantity being detected by the 2nd sensitive surface 192b, can detect crawling that steel band 116 to which direction moves and whether occur.
As mentioned above, in the driving tester 1 of present embodiment, corrected with crawling of straightening mechanism 150.In addition, driving tester 1, on the above-mentioned basis with straightening mechanism 150, also possesses the band guide mechanism 180 crawling for preventing steel band 116.As shown in Figure 3 and Figure 4, possess 4 groups of guiding rollers 181 that are supported with guide mechanism 180, this guiding roller 181 can rotate freely.For guiding roller 181, its turning axle configures towards vertical direction, and, by the spring not representing in figure, this guiding roller 181 is exerted pressure at transverse direction towards the end of steel band 116.
In Fig. 6, represent the stereographic map of guiding roller 181.As shown in Figure 6, be formed with at the periphery of guiding roller 181 the groove 181a extending at circumferencial direction.This groove 181a is a bit larger tham steel band 116 thickness mode with groove width forms, so that in 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 if therefore apply the power of Width to steel band 116, crawling of steel band 116 is also difficult to occur.And then as previously mentioned, even if steel band 116 crawls a little, this crawls and also can be corrected rapidly by band straightening mechanism 150 (Fig. 3, Fig. 4).
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 by embodiments of the present invention make the axle 111a of anterior pulley 111 in the time that vertical axes is rotated with straightening mechanism 150, can not apply bending load to axle 111a.Below, the supporting structure of axle 111a is described.
Fig. 7 is the sectional view that cuts off the anterior pulley 111 of present embodiment with the face perpendicular to fore-and-aft direction.As shown in Figure 7, the axle 111a of anterior pulley 111 is installed on the main body 111c of anterior pulley 111 by combination angular contact bull bearing (the angular contact ball bearing) 111b of 2 groups.Therefore, axle 111a does not rotate, and main body 111c rotates around axle 111a.In addition, it is combined that combination angular contact bull bearing 111b is respectively the back side, with allow be applied to axle 111a any direction compared with macrobending load.
Support axle (shaft) 162 and housing (housing) 163 that the bearing unit 160 of a side (in the figure left side) end of the axle 111a of anterior pulley 111 possesses 2 groups of ball thrust bearings 161, extends in vertical direction.Housing 163 is fixed on feed nut 153b and slide block 154b.In addition, be provided with at a side end of axle 111a the through hole 111d extending in vertical direction.Axle 162 is inserted in this through hole 111d.In addition, axle 162 is fixed on housing 163 by not shown bolt (bolt).
A track plate 161a of ball thrust bearing 161 is installed in bearing unit 160, and another track plate 161b is installed in the axle 111a of anterior pulley 111.Therefore, the axle 111a of anterior pulley 111, in the position of ball thrust bearing 161, is supported in the mode that can freely rotate around axle 162.
Like this, the axle 111a of anterior pulley is bearing in upper frame portion 132 in the mode that can freely rotate around vertical axes by bearing at its two ends.Therefore, even by feed screw 152a or 152b towards each other contrary direction drive and make the axle 111a of anterior pulley 111 tilted at surface level, the two ends of axle 111a also can freely be rotated around vertical axis with respect to upper frame portion 132, can produce hardly bending stress on axle 111a.
In addition, globe bearing 171 is so that axle 111a not only can be around vertical axes and the mode bolster 111a that can rotate around the axis of fore-and-aft direction and around horizontal axis.Therefore, though axle 111a because of the weight bending of automobile C (Fig. 1), the center of globe bearing 171 center and axle 111a still can be by aligning automatically.
