<p>PURPOSE: To readily obtain a sliding connection part between a shaft and a second disc by fixing a stationary disc to the hub of a wheel, providing a movable disc coaxially therewith, pressing first, second and third brake linings to both the surfaces of the discs and equally supporting three pairs of bearings with respect to the axis of the wheel. CONSTITUTION: A stationary disc 10 is fixed to the hub 1 of a wheel and a movable disc 33 is provided coaxially therewith and rotates integrally with a hub 1 and is movable axially. First, second and third brake linings 50, 51 and 52 are provided so as to make pressing contact with both disks 10 and 33. A caliper 53 is provided as a means for pressing the brake linings 50, 51 and 52 to both the discs 10 and 33. The hub 1 supports bearings 15 equally arranged with respect to an axis. A column 16 freely slides on the bearings 15. Hangers 17 are mounted on the column 16 and connected to the movable disc 33. Thus, the connecting part of the shaft and the second disc can be simply obtained.</p> |
