Title:
ELECTRIC ACTUATOR AND V-BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION USING THE SAME
Document Type and Number:
Japanese Patent JP2016142384
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To connect a ball screw 71 and an arm member 60 by using only a pin, and to obtain favorable maintenance performance.SOLUTION: A V-belt type continuously variable transmission makes a movable pulley 32 of a drive pulley 30 advance and retreat with respect to a fixed pulley 31 by an arm drive unit 70 which is composed of a ball screw or the like via an arm member 60. A shaft part 62 of the arm member and a connecting rod 78b of a connecting member 78 which operates by the ball screw are connected to each other by a plunger pin. The plunger pin is internally fit with a pin (engagement piece) 95 which is energized by a coil spring 96 to a penetration hole 93 of the connecting rod, and the shaft part 62 and the connecting rod 78b are connected to each other by fitting the pin into the penetration hole 94 of the shaft part 62, and bridging it over both the pin and the penetration hole. By pushing the pin 95 to the connecting rod side while withstanding the spring 96, the shaft part and the connecting rod are separated from each other. Therefore, the connection and release of the shaft part and the connecting rod become easy.SELECTED DRAWING: Figure 11
