Electro- hydraulic drum brakes

YWZ9 series electro-hydraulic drum brake

Main Design Features

l  Interlocking shoe clearance balancing device and shoe auto-aligning device constantly equalize the clearance of brake shes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brake wheel.

l  At main hinge points are equipped with self-lubricating bearings, which make higher efficiency of transmission and longer performance life, and lubricating is unnecessary during the course of operation.

l  Brake spring is arranged inside square tube and surveyor’s rod is placed on one side. It is easy for customers to read braking torque value and avoid the troubles of measuring and computing.

l  Brake lining is of card whole piece shaping structure, which is easy and quick to replace. Brake lining of various materials such as half metal ( non-asbestos) hard and haft-hard, soft (include asbestos) substance are available for customer to choose.

l  Our company’s new types of thrusters are adopted, which work acutely and have long life.

Options

l  Hand release lever.

l  Open (release) or close limit-switch, which indicates whether the brake is properly released or closed.

l  Wear-self-compensation device, which realizes endless self-compensation of shoe clearance an torque when lining wears.

l  Lining-wear limit-switch, equipped which signals will shown when wear of lining reaches the limit (note: self-compensation device should be equipped in application)

l  Adopt thruster with fall delay value as drive system which can realize closing delay or brake.
