Embodiment Construction

[0021] Preferred embodiments of the present invention will be described with reference to the drawings.

[0022] 1 is a sectional perspective view schematically showing a part of the essential part of a chain-type continuously variable transmission (hereinafter referred to as a continuously variable transmission) as a power transmission device including a power transmission chain according to an embodiment of the present invention. Referring to FIG. 1 , a continuously variable transmission 100 is mounted on a vehicle such as an automobile. The continuously variable transmission 100 includes: a driving pulley 60 made of metal (structural steel, etc.) as a first pulley; a driven pulley 70 made of metal (structural steel, etc.) as a second pulley; An endless power transmission chain 1 (hereinafter referred to as the chain) between the two pulleys. Also, for easy understanding, the chain 1 in Fig. 1 only shows a part of the section.

Abstract

A power transmission chain (1, 1A, 1B) is provided with a plurality of connecting members (3, 4; 3A, 4A) that connect a plurality of links (2, 2B) to each other so as to be bendable. Each connecting member (3, 4; 3A, 4A; 3B) includes a power transmission member (3, 3A, 3B) opposed to a predetermined counterpart member (4, 4A, 2B). The counterpart member (4, 4A, 2B) includes either a member interposed between the power transmission member (3;3A;3B) and the corresponding link (2; 2B) or the corresponding link (2B). Opposed portions (12, 20; 12A, 20A; 12B, 31) of the power transmission member (3; 3A; 3B) and the counterpart member (4; 4A; 2B) contact each other at a contact portion (T, TA, TB) that is displaced as a result of bending between the links (2; 2B) in a contact condition including at least either a rolling contact or a sliding contact.

Description

[0001] technology area [0002] The present invention relates to a power transmission chain and a power transmission device equipped with the transmission chain. Background technique [0003] As an endless transmission chain used in a power transmission device such as a continuously variable transmission (CVT: continuously variable transmission) of a motor vehicle, it has been proposed to arrange a plurality of links (links) along the direction in which the chain travels, and to connect adjacent links in the direction of transmission. A power transmission chain in which rings are connected by a pair of mutually rolling pins (see, for example, Documents 1 to 3 below). [0004] Document 1: Japanese Patent Application Laid-Open No. 8-312725 [0005] Document 2: Publication No. 63-201248 of Shikaizhao [0006] Document 3: Japanese Patent Application Laid-Open No. 1-169150 [0007] The aforementioned power transmission chain is used under tension. With buckling between the link...
