Brake drum is one of the indispensable parts of the car. To understand how to improve the quality of the brake drum, it is necessary to understand the working principle and structure of the brake drum. In fact, the drum brake works by using the brake transmission mechanism to cause the brake shoe to press the brake lining against the inside of the brake drum, thereby generating a braking force, and decelerating the wheel or stopping it within a short distance as needed to ensure Driving safety and ensuring that the car is parked reliably cannot be automatically slipped.
In fact, after the working surface of the brake drum is assembled with the hub, it needs to be finished by bearing hole positioning. The requirements for roundness and coaxiality tolerance of the working face of the mini-car are ≤0.03mm, the radial runout is ≤0.05mm, and the static unbalance is ≤1.5N/cm. Therefore, if you want to achieve the above performance indicators, you need to achieve through the brake drum balancer.
If the brake drum detects an unbalance in the rotating state, it is necessary to remove the quality that affects its balance according to the standard, which is what we call deduplication. Subsequent re-balancing detection is required to achieve the specified brake drum accuracy level.
