BELT BRAKE DEVICE CONTROL MECHANISM Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: mechanism has a lever system with stationary supports, a lever connected to a belt, a reverse lever and a control lever which are mounted on the supports and kinematically connected. The stationary supports on which the reverse and control levers are mounted are located on the line perpendicular to the line connecting the stationary supports of two flexible members. The reverse lever and the control lever are pivotally connected by two links located along diagonals of an equilateral trapezoid which sides are located between the middles of the arms of the reverse lever and the ends of the arms of the control lever respectively. The lever connected to the brake belt is mounted on one of the stationary supports with the first flexible member. EFFECT: improved structure. 2 cl, 2 dwg
