Pulley type constant velocity joint

Abstract

A pulley type constant velocity joint may include first and second shafts for transmitting and receiving power therebetween, first and second pulleys being fixedly attached to ends of the first and second shafts, respectively, and first and second wires wound around circumferential grooves of the first and second pulleys to allow the first and second pulleys to be rotated with reference to the center of the first and second pulleys. Further, first and second support frames may be included for rotatably supporting each center of the first and second pulleys, both ends of which are rotatably connected to each other. The constant velocity joint may also include two rotating pins to rotatably connect the first and second pulleys and the frames at the centers of the first and second pulleys, and two connecting pins for connecting the first and the second frames at their ends and for allowing rotation of the frames.
