What is a Rotochamber?

The rotochamber is an actuator which converts the energy of air pressure into mechanical force. The rolling type diaphragm provides long life and gives a constant output force throughout the entire stroke. One end of the diaphragm is clamped to the inside wall of the body by the outer clamp.

How many types of brake chambers are there?

There are two kinds of air brake chambers – service and spring brake chambers. A service brake chamber contains a flexible rubber disc called a diaphragm, a metal rod called a pushrod and a return spring.

How many brake chambers are there on a tractor and trailer?

An 18-wheeler is usually equipped with 10 brake chambers, 5 axles with a brake chamber on each side.

How many brake chambers does a truck have?

What is a spring brake chamber?

A brake chamber that includes both service brake and spring brake sections is called a spring brake chamber. Spring brake chambers apply the brakes by means of a large coil spring that provides enough force to hold the brakes in the applied position, instead of using air to apply the brakes.

What kind of brake chamber does a truck use?

What’s the difference between Type 12 and 30 brake chambers?

The type refers to the effective area in square inches that the air works against, a type 12 has 12 square inches of surface area and a type 30 has 30 square inches of service area etc. This means as the type of service chamber increases the diameter grows and so does its potential output for braking pressure.

What does the type number of a rotochamber mean?

The rotochamber is an actuator which converts the energy of air pressure into mechanical force. The type number of the rotochamber indicates the actuator’s diaphragm effective area (Type 30 – 30 sq. in. of diaphragm) and the various sizes available give a wide range of output force and length of stroke.
