Embodiment Construction

[0031] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In addition, the following description is merely an illustration in nature, and does not intend to limit the present invention, its application, or its use. In addition, the drawings are schematic, and ratios of dimensions and the like do not necessarily match actual ones.

[0032] figure 1 The tire load applying device 1 according to the present embodiment is shown. This tire load adding device 1 includes: a support base 5 having a support surface 4 on which a part of the tread portion 3 of the tire 2 abuts; a support member 6 for supporting the inner peripheral side of the tire 2; A longitudinal load imparting mechanism constituted by a pair of longitudinal load imparting members 7A, 7B pressing the tire 2 against the support surface 4 , and a lateral load imparting member 8 extending the tire 2 in the horizontal direction via the support member 6 .

Abstract

The present invention provides a tire load attaching device and a tire inspection device, which are simple in structure and inexpensive and attach appropriate load to a tire. A tire load application device includes a support base (5) having a support surface (4) against which part of a tread surface (3) of a tire (2) abuts, a support member (6) configured to support an inner circumferential side of the tire (2) and protrude toward both end sides in a tire axial center direction, and a longitudinal load application mechanism (7A, 7B) configured to apply a load to both end portions of the support member (6) and press the tire (2) toward the support surface (4).

Description

technical field [0001] The invention relates to a tire load adding device and a tire inspection device. Background technique [0002] In tire design, it is important to accurately evaluate the deformation state and strain distribution (tension distribution) of cord members such as a frame cord and a belt. [0003] In the finite element method (Finite Element Method, FEM) generally used for tire design, the strain of the cord component generated in the initial state of the finished tire is not considered in the finished tire. In order to improve the accuracy of the FEM, a tire model that takes into account the strain of the cord member generated in the initial state is required. [0004] Therefore, a tire internal structure observation device has been proposed, which, for example, emits X-rays of a radiation source to a tire pressed by a load-applying mechanism and detects it with a radiation detector, thereby observing the internal structure of the tread portion of the tire...
