Good product, good way

Cast iron truck brake drum

The brake drum is a cast iron piece shaped like a tambourine, which is fixed to the tire and rotates at the same speed. When braking, oil pressure is used to push the brake shoes to contact the inner edge of the brake drum, and the friction generated by the contact is used to suppress the rotation of the tire to achieve the purpose of braking.

 Materials

Cast iron truck brake drum: cast iron

Description

OE NO.:3014210901
Warranty:1 year
Type:brake drum
Color:standard

Definition

The brake drum is a cast iron piece shaped like a tambourine, which is fixed to the tire and rotates at the same speed. When braking, oil pressure is used to push the brake shoes to contact the inner edge of the brake drum, and the friction generated by the contact is used to suppress the rotation of the tire to achieve the purpose of braking.

Features

The working surface of the brake drum is generally finished after being assembled with the wheel hub by positioning the bearing holes. Mini cars require roundness and concentricity tolerances of the working surface ≤ 0.03mm, radial runout ≤ 0.05mm, and static imbalance ≤ 1.5N · cm.

A) No noise,no dust,long life and polution free characteristics.

B) Stable performance at high-temperature.

C) Better rim appearance.

D) With OE designed shim,slots and chamfer.

E) High quality.

Function and characteristic

Integral casting
The brake drum is integrally cast from high-strength gray cast iron or alloy cast iron containing Cr. This brake drum has a simple structure, convenient processing, and large heat capacity, but has a large mass, and is mostly used for medium and heavy vehicles.

Combination of steel plate and cast iron
The brake drum is composed of a steel plate stamped drum plate and a cast iron drum ring, which has a small mass and is mostly used for cars and light cars.

Combination of light alloy and cast iron
The main body of the brake drum is a light alloy material (such as aluminum alloy), which is lined with a cast iron ring. This kind of brake drum is not only small in weight, but also good in heat dissipation, and is mostly used in cars.
