Embodiment Construction

[0035] Preferred embodiments of the present invention will be described with reference to the drawings. figure 1 It is a perspective view typically showing the configuration of a main part of a power transmission chain (hereinafter, simply referred to as a chain) employed in the chain-type continuously variable transmission according to the first embodiment of the present invention. refer to figure 1 , the chain 1 includes: a plurality of link plates 2 arranged in the chain advancing direction X and the width direction W of the chain; a plurality of chain pins 3 for interconnecting these link plates 2; slightly shorter than the chain pins 3 Multiple narrow strips of 4.

[0036] figure 2 yes means figure 1 The shown cross-sectional view of the main part of the chain 1 shows three sets of link plate groups including a plurality of link plates 2 at the same positions in the chain advancing direction X. As shown in FIG. Specifically, the first link plate group 51 , the second...

Abstract

A power transmission chain, comprising a plurality of link plates having through holes and arranged at specified intervals in a chain running direction and a chain lateral direction and a plurality of pins inserted into the through holes and flexibly connecting the plurality of link plates to each other. Since the link plates are arranged at the specified intervals in the chain lateral direction, the link plates adjacent to each other are prevented from coming into frictional contact with each other when the power transmission chain is driven, and the lowering of its transmission efficiency can be suppressed.

Description

technical field [0001] The present invention relates to a power transmission chain used in a chain-type continuously variable transmission of a vehicle or the like, a manufacturing method thereof, and a power transmission device using the power transmission chain. Background technique [0002] As a continuously variable transmission (CVT: Continuously Variable Transmission) of an automobile, for example, there is a transmission having: a driving pulley provided on the engine side; a driven pulley provided on the driving wheel side; An endless power transmission chain of a plurality of link plates and a plurality of chain pins interconnecting the link plates. In such a so-called chain-type continuously variable transmission, some sliding contact is made in the circumferential direction of the sheave surface through the conical sheave surface of each pulley and a part of the chain constituent members such as the chain pin end surface of the chain. To generate traction, and th...
