Abstract: PURPOSE:To easily and strictly detect interference between interfaces by deciding the relation of the surface and the reverse side between the interfaces, and deciding whether a common part exists within a range of each interface on an intersecting line between the interfaces or not. CONSTITUTION:When distances d1-d4 between each apex P1-P4 of an interface SA and an interface SB (in reality, an unlimited plane of the interface SB) are all positive, the former exists on the surface of the interface SB, and when the distances d1-d4 are all negative, it exists on the reverse side of the interface SB, therefore, it can be detected that there is no interference between the interface SA and SB. On the other hand, in case the distances d1-d4 are divided into positive and negative, the interface SA interferes with the unlimited plane of the interface SB, and there is the possibility of an interference between the interface SA and SB. Subsequently, in order to check whether the interfaces SA, SB interfere with each other actually, an intersecting line CL between the interfaces SA, SB and the unlimited plane is derived, apexes of the interfaces SA, SB are projected thereto, and by checking common parts WA, WB of its ranges WA, WB, the check can be executed more strictly.

Filed: 1989-06-06
Abstract: PURPOSE:To decrease pattern noise by providing Iongitudinal and transverse grooves, which cross with each other, on a tread portion, and by setting a pitch of the transverse grooves so that a product of the pitch by integer is almost equal to ground contact length under normal condition. CONSTITUTION:On a tread portion T of a tire 1, there are plural longitudinal grooves G, which are continuously elongated in the peripheral direction of the tire. Consequently, the tread portion T is divided into a central rib R1, an intermediate rib R2 and a shoulder rib R3, respectively. Moreover, on the tread portion T, there are plural transverse grooves Y which are elongated so as to cross with each longitudinal groove G. In this case, a pitch P1 of an inner transverse groove Y1 formed on the intermediate rib R2 is determined so as to be uniform. In addition, a product l1 of the pitch P1 of the transverse groove by integer is determined so as to be almost equal to ground contact length L of the tire 1 under normal condition. In this way, sound pressure waves generated at the moment of contact and separation of the transverse grooves Y with a road surface interfere with each other. As the result, noise can be decreased.
