Heavy Truck Brake Disc

Product introduction:

Brakes include disc brakes, drum brakes, and air brakes. Many older cars have front discs and rear drums. Many cars have disc brakes front and rear. Because the heat dissipation of disc brakes is better than that of drum brakes, it is not easy to produce thermal recession under high-speed braking conditions, so its high-speed braking effect is better. But when the brake is cold at low speed, the braking effect is not as good as that of the drum brake. The price is more expensive than the drum brake. Therefore, many mid-to-high-end cars use full-disc brakes, while ordinary cars use front discs and rear drums, and relatively low-speed trucks and buses that require large braking force still use drum brakes.

The drum brake is sealed and shaped like a drum. There are also many brake pots in China. It rotates when driving. There are two curved or semicircular brake shoes fixed inside the drum brake. When stepping on the brakes, the two brake shoes are stretched out under the action of the brake wheel cylinder, propping up the brake shoes and rubbing against the inner wall of the brake drum to slow down or stop.

Material requirements:

The material of the brake disc is my country's gray cast iron 250 standard, referred to as HT250, which is equivalent to the American G3000 standard. The requirements for the three main elements of the chemical composition are: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9. Mechanical performance requirements: tensile strength>=206MPa, bending strength>=1000MPa, deflection>=5.1mm, hardness requirement: between 187∽241HBS.

nickname:

In English, the brake disc is usually represented by: BRAKE DISC or BRAKE ROTORS, and the brake drum is represented by: BRAKE DRUM. In addition, in southern my country, brake discs are also called brake discs and brake discs. In fact, they all refer to one thing.
