Abstract

The object of the present invention is to provide a V-shaped transmission mechanism that can reduce the vibration caused by the resonance of both pulleys and has good durability in an automatic transmission mechanism composed of a variable drive side speed change pulley and a driven side speed change pulley. Belt automatic transmission. The V-belt automatic transmission of the present invention consists of a drive side speed change pulley (A) with a centrifugal roller (4) inside, a driven side speed change pulley (B), and the driven side speed change pulley (B) A centrifugal clutch (C) connected and equipped with a centrifugal hammer (12) is formed. Among the number of centrifugal rollers (4) arranged on the driving side speed change pulley (A) and the number of centrifugal hammers (12) arranged on the aforementioned centrifugal clutch (C), the larger number is relative to the smaller one The scale of numbers is non-integer.

Description

Technical field

[0001] The present invention relates to a V-belt type automatic transmission, which is composed of a variable drive-side speed-change pulley and a driven-side speed-change pulley, which can reduce the vibration caused by the resonance of the two pulleys and has good durability. Background technique

[0002] The ratio of the set number between the centrifugal roller arranged in the movable wheel of the driving (or driving) side speed change pulley in the V-belt automatic transmission and the centrifugal hammer of the centrifugal clutch arranged on the driven side speed change pulley (drive The number of centrifugal rollers of the side speed change pulley / the number of centrifugal hammers of the driven side speed change pulley) is generally an integer value. Such a structure in which the aforementioned ratio is set to an integer value is common in the prior art. For example, it has been disclosed in many documents such as Patent Document 1 below. In the case of this...
