Brake hub is a kind of brake hub, of which the brake hub material on the rear bridge of the electric tricycle is mostly cast iron, its processing accuracy requirements are strict, the following to summarize: the advantages of the brake hub
1, the brake system is not sealed, so the brake wear of the fine will sink on the brake system, the centrifugal force of the disc brake can be all water, dust and other pollution thrown out to maintain a certain degree of cleanliness.
2, the disc brake parts are independent, which is easier to maintain than the drum brake.
3, the drum brake has a good self-braking effect, because the brake to make the outer sheet, the wheel rotation with the outer tensioned brake drum twisted an Angle, the brake to make the outer sheet tension, that is, the greater the braking force of the brake, the more obvious the situation.
Therefore, generally large vehicles still use drum brakes, in addition to the lower cost, large cars and small cars drum brakes, the difference may be large using pneumatic assistance, and small cars using vacuum assistance to help brake!
