Title: Back pedalling bicycle brake - has brake shoe release cams on drive sleeve around fixed spindle
Inventor: SEGAWA TAKASHI
IPC: B62L5/16
Filed: 1978-04-20
Abstract: The back pedalling brake for a bicycle consists of a hub (1) turning on a fixed shaft (4) via a ball race and a drive sleeve (6). The drive sleeve is mainly cylindrical and is turned by a chain sprocket. Two semi cylindrical brake shoes (11) able to move outwards radially are fitted close to the spoke hub inner surface and secured to the lifting cone at one end. The drive sleeve has an extension (61) which passes below the brake shoes to carry a number of cam surfaces (12). A roller bearing cage (13) is fitted between the sleeve extension and the brake shoes so that the rollers rest between the cams. When the drive sprocket is turned backwards, the cams push against the rollers to press the brake shoes outwards radially to exert a braking force on the spoke hub (1). The brake shoes are released by a second set of rollers (15) whose cam surfaces slant in the opposite direction to the first cams.
