[0113] refer to Figure 4 and Figure 5 , the tire testing device 201 according to the second embodiment of the present invention will be described. In addition, the same reference numerals are assigned to the same constituent elements as those described above, and description thereof will be omitted. The tire testing device 201 has substantially the same configuration as the tire testing device 1 of the first embodiment except for the following points.

[0114] The beam 240 as a whole is not a linear shape extending in the horizontal direction, but a shape in which the center of the longitudinal direction protrudes upward. Specifically, the beam 240 has a linear horizontal portion extending horizontally at the center in the longitudinal direction, and two inclined portions extending obliquely downward from both ends of the horizontal portion in the longitudinal direction.

[0115] Both ends in the longitudinal direction of the beam 240 (ie, ends of the two inclined portion...

[0143] Next, refer to Image 6 A tire testing device 301 according to a third embodiment of the present invention will be described. In addition, the same reference numerals are assigned to the same constituent elements as those described above, and description thereof will be omitted. The tire testing device 301 has substantially the same configuration as the tire testing device 1 of the first embodiment except for the following points.

[0144] In the tire testing apparatus 301 of the third embodiment, unlike the first embodiment, the vertical frame 30a, 30b is not inside (in Image 6 Only one vertical frame 30a is shown in . ) Ball screws 31a, 31b, motors 32a, 32b, and electromagnetic brakes 33a, 33b are provided. On the other hand, hydraulic cylinders 331, 331 having pistons and piston rods are provided inside the vertical frames 30a, 30b.

[0145] The hydraulic cylinders 331, 331 extend in the vertical direction in the respective inner spaces of the vertical frames 30...

[0151] refer to Figure 7 A tire testing device 401 according to a fourth embodiment of the present invention will be described. In addition, the same reference numerals are assigned to the same constituent elements as those described above, and description thereof will be omitted. In the tire testing apparatus 401 of the fourth embodiment, an axis adjustment mechanism capable of adjusting the axis of the upper spindle 47 is added to the tire testing apparatus 1 of the first embodiment. The details of the structure of this shaft center adjustment mechanism will be described below.

[0152] such as zoom in Figure 7 The diagram of the main part B is Figure 8 As shown, the tire testing apparatus 401 has a laminated rubber support 441 as an axis center adjustment mechanism. The beam 440 has a cylindrical part 440a and a cover member 440b fixed to the cylindrical part 440a. The cylindrical portion 440a is a cylindrical member extending in the vertical direction, and houses t...

Abstract

The misalignment of the rotation axis of the upper chuck with respect to the rotation axis of the lower chuck due to the separation force is effectively suppressed. The tire testing device (1) includes the following components: the vertical frame (30a, 30b), supported by the lower frame (20); the beam (40), which is erected between the vertical frames (30a, 30b) and can Move in the vertical direction; the upper chuck (45) is installed in the center of the beam (40) in the length direction; the lower chuck (25) is installed in the lower frame, and when viewed from the vertical direction, the upper rotating part (47) The rotation axis is located at the center of the straight line connecting the support points of the beams (40) supported by the vertical frames (30a, 30b).

Description

technical field [0001] The present invention relates to a tire testing device for performing a performance test of a tire. Background technique [0002] The gazette described in Patent Document 1 discloses a tire testing device including a lower frame, a portal frame, a lower chuck, and an upper chuck. The portal frame is erected on the lower frame. The portal frame includes a pair of vertical frames extending vertically upward from both ends in the longitudinal direction of the lower frame, and a horizontal frame extending between upper ends of the vertical frames. The lower chuck is mounted on the lower frame. The upper chuck is mounted on the horizontal frame of the portal frame. The lower chuck and the upper chuck each have a rotating member. In this tire testing apparatus, air is supplied to the internal space of the tire while the tire is clamped between the lower chuck and the upper chuck. In addition, various performance tests were performed in a state where eac...
