We know that if you want to slow down a car at high speed, use the brakes can do.
But there are many ways to brake, do you know?
Today we understand the drum brake, which belongs to the brake system of the drum brake. Compared with the inertia brake traction system, it is by contact with the drum. The inner edge generates friction to suppress the rotation of the tire to achieve the purpose of braking.
It has an automatic brake function, and the brakes use a lower oil pressure. The machining of the parts of the drum brake is relatively simpler and the manufacturing cost is relatively low. Installation is also relatively easy.
However, it is worth noting that the drum brakes have poor heat resistance, and the drum brakes will increase in diameter after being heated, adapting to thermal expansion and contraction. The principle is that after the brake is easily caused, the stroke is not close to the other brakes, and the expected situation is not achieved. Therefore, the high temperature generated by the continuous braking should be avoided during driving, and the braking performance is weakened.
And the brakes make the parts complex, the brake clearance needs to be adjusted, so maintenance is not easy, it is recommended not to do high-frequency brake action when braking, to ensure the brakes safety.
