Title:

EDDY CURRENT DECELERATION DEVICE EQUIPPED WITH POWER GENERATION FUNCTION

Document Type and Number:

WIPO Patent Application WO/2015/122156

Kind Code:

A1

Abstract:

An eddy current deceleration device that is equipped with a power generation function is provided with a braking drum (1), a magnet-holding ring (2), and a turning switch mechanism. The braking drum (1) is fixed to a rotating shaft (10). The magnet-holding ring (2) is arranged on the inside of the braking drum (1) and holds a permanent magnet (3) at regular intervals across the circumferential direction so as to face the inner circumferential surface of the braking drum (1). The turning switch mechanism comprises a switch plate (4) that switches to a state in which a magnetic circuit is generated between the permanent magnet (3) and the braking drum (1) when braking and the magnetic circuit is not generated when not braking. A protruding section (1c) is provided at regular intervals across the end surface (1b) of the braking drum (1) in the circumferential direction. A power generation coil (8) is provided to a non-rotating section of a vehicle at regular intervals across the circumferential direction so as to face the area of the end surface (1b) of the braking drum (1). The positions of the permanent magnet (3) and the coil (8) match in the circumferential direction when braking.
