FLEXIBLE BOOT FOR CONSTANT VELOCITY UNIVERSAL JOINT
Document Type and Number:
WIPO Patent Application WO/2007/023803
Kind Code:
A1
Abstract:
A flexible boot (1) enabling the simplification of boot mounting operation and boot manufacturing steps. The flexible boot is disposed between the outer joint member (2a) and the intermediate outer periphery of the shaft (2e) of a constant velocity universal joint storing torque transmission members (2c) between the outer joint member (2a) and an inner joint member (2b) and formed by extending the shaft (2e) connected to the inner joint member (2b) to the outside of the joint. The flexible boot comprises a tubular small diameter part (1a2) fixed to the outer peripheral surface of the shaft (2e), a large diameter part (1a3) fitted to the inner peripheral surface of the outer joint member (2a) through a reinforcement ring part (1b), and a bellows part (1a1) connecting the small diameter part to the large diameter part. The flexible boot is characterized in that the outer peripheral surface (1b3) of the reinforcement ring part (1b) is fitted to the inner peripheral surface [step part (2a2)] of the outer joint member (2a).
