BAND BRAKE CONTROL MECHANISM Russian patent published in 1999 - IPC

FIELD: mechanical engineering; band brakes. SUBSTANCE: control mechanism has leverage with fixed supports onto which levers mechanically coupled with bands, two change-over levers and control lever are installed. Two change-over levers are arranged on line perpendicular to line connecting fixed supports of two flexible members. Change-over lever and control lever are hinge-connected by two tie-rods located along diagonal of equilateral trapezium whose sides are arranged, respectively, between middles of arms of change-over lever and middles of additional arms of control lever. levers coupled with brake bands are installed on one fixed support with corresponding flexible members. EFFECT: possibility of simultaneous control over four kinematic chains of belt brakes. 1 dwg
