Title:
PULLEY STRUCTURE OF BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION AND COUPLING METHOD BETWEEN MOVING SHEAVE OF PULLEY AND HYDRAULIC ACTUATOR MEMBER
Document Type and Number:
Japanese Patent JP3441873
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure the stable strength of coupling between a moving sheave and a hydraulic actuator member without the occurrence of a trouble, such as cracks and necking.
SOLUTION: A flange part 24 having an annular groove 23 is formed in a protruding state on the back 22 of a moving sheave 20, a steel wire 40 is wound around the bottom 23a of the annular groove 23 to form a plastic flow regulation part. By effecting caulking after the piston member 31 of a hydraulic actuator is fitted in a flange part 24, the plastic flow of a piston member 31 is rendered adequate by a steel wire 40. Even by a low caulking amount, an area of contact between the two sides 23b of the annular groove 23 and the piston member 31 is ensured, and the stable strength of coupling between the moving sheave 20 and the piston member 31 is ensured.
