HYDRAULIC DRIVE MECHANISM OF A BAND BRAKE

Hydraulic fluid from tank 1 flows by gravity into pressure cylinder 2. When brake pedal 3 is depressed, cam 4 turns about fixed axis A and moves piston 5 to the left. Fluid forced out of the left end of cylinder 2 by piston 5 is delivered through pipeline 6 to operating cylinder 7, moving piston 8 to the right. Through lever 9, this applies tension to the brake band which brakes drum 10. When peda…
