Title:
POWER TRANSMISSION DEVICE FOR A WATER PUMP
Document Type and Number:
WIPO Patent Application WO/2011/078508
Kind Code:
A2
Abstract:
Provided is a power transmission device for a water pump for cooling automobile engines, wherein power regulation between a disk and hub in the power transmission device for a water pump can be rapidly and accurately effected, and wherein wear and damage to constituent parts can be prevented. The power transmission device comprises a pulley, a magnetic flux generating means, a disk assembly, and a hub assembly. The disk assembly comprises a disk, a friction ring which makes frictional contact with the hub assembly, and a resilient ring which resiliently presses the friction ring towards the hub assembly. When the attracting magnetic flux of the magnetic flux generating means is not applied, the friction ring makes frictional contact with the hub assembly due to resilient pressing of the resilient ring, whereas, when the attracting magnetic flux is applied, the disk moves towards the pulley such that the frictional contact between the friction ring and the hub assembly is broken.
