  Then, after the test of the rear wheel is completed, the vehicle under test is advanced, and the test of the vehicle under test is completed.

  If necessary, the next vehicle under test is measured in the same manner as described above, first by measuring the number of axles of the front and rear wheels of the vehicle under test and the required distance between the axles. Determine the roller devices to be tested and test each one.

(2.7. Effect)

  In the present invention, the fixed roller device 2 and the other movable roller device 4 can test the front axles of most of the vehicles under test, and the fixed roller device 2 and one movable roller device 3. Thus, most of the rear wheel two-axis tests can be performed. Therefore, even in the case of a four-wheeled vehicle having two front wheels and two rear wheels, each roller device is set in a desired manner before placing the vehicle under test on the roller device. Since it can be moved to the position, the working time can be shortened.

  In addition, even when testing a plurality of large vehicles such as a front wheel biaxial vehicle and a rear wheel biaxial vehicle, the movement of the roller device can be reduced, so that the working time can be shortened.

  Further, the front wheel two axes are measured by using the fixed roller device 2 and the other movable roller device 4, and the rear wheel two shafts are measured by using the fixed roller device 2 and one movable roller device 3. Therefore, the selection of the roller device is facilitated, and it is possible to reduce the placement of the wheel on the wrong roller device when the vehicle under test is actually moved.

  In addition, since the moving stroke of each movable roller device can be reduced, the width and depth of the pit can be reduced, and the space can be made more efficient.

  Then, the large vehicle 7 is advanced, and first, the wheel T of the front wheel shaft 8c of the large vehicle 7 is placed on, for example, the fixed roller 2, and the test is performed.

  After the front wheel test is completed, the large vehicle 7 is advanced, and as shown in FIG. 5, the rear front shaft 8a of the large vehicle 7 and the wheels T of the rear rear shaft 8b are respectively connected to the fixed roller device 2 and the It is placed on one mobile roller device 3 and tested.

  Then, after the rear wheel test is completed, the large vehicle 7 is moved forward, and the test of the vehicle under test is completed, and if necessary, preparation for the test of the next vehicle under test is performed. .

  As described above, using only the fixed roller 2 and the movable roller 3, it becomes possible to perform vehicle tests on the rear front axle and rear rear axle wheels of almost all rear wheel biaxial vehicles.

  The distance between the rear front shaft 8a and the rear rear shaft 8b is normally 1300 mm. Therefore, by setting the distance between the fixed roller 2 and the movable roller 3 to 1300 mm, the one movement Without moving the roller 3, many other rear wheel 2-shaft large vehicles can be tested.

  When the distance between the two rear wheel shafts is out of the range, the arithmetic and storage processing device detects two roller devices that can measure the rear wheel two shafts. When the two roller devices that can measure the two rear wheel axes are not detected, the two rear rear shafts are measured by the fixed roller device 2, for example.

(When testing 3.2.4 large axles) (See Figures 6 and 7)

  Before the wheels of the vehicle under test are placed on the roller devices, the number of front and rear wheels of the vehicle under test and the required distance between the axles are measured. The front wheel shaft is 2 and the rear wheel shaft is 2 And the distance between the axes of the two front wheels and the distance between the axes of the two rear wheels are measured.

And the distance between the two axes of the front wheels is measured.

  In the case of the large vehicle 11 with two front wheels and one rear wheel, such as a tank truck, the distance between the front front shaft and the front and rear shafts of the two front wheels is 1700 to 2850 mm as described above. Therefore, in the case of the large vehicle 11 having a front-to-front axis of the two front wheels and the front-rear axis in the range of 1700 to 2600 mm, it is within the second desired range. Judgment is made.

  Further, since the rear wheel has one axis, the fourth determination is made by the arithmetic storage processing device.

  And since the said 2nd judgment was made, the said other movable roller apparatus 4 moves so that it may become the measured center distance of the front-wheel 2 axis | shaft.

  Then, the large vehicle 11 is advanced, and as shown in FIG. 8, first, the front front shaft 12a of the front wheel 2 shaft and the wheel T of the front and rear shaft 12b of the large vehicle 11 are respectively connected to the other movable roller device. 4 and the fixed roller device 2 to be tested.
