How Many Gears Does a Handbrake Have?
1 Answers
Generally, a handbrake has three gears. This is because the tightness of the handbrake cable varies when pulling it, resulting in different levels of braking force applied under different circumstances. Below is some relevant information about handbrakes: Principle: The professional term for a handbrake is an auxiliary brake, which operates differently from the main brake system. It uses a steel wire cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel wire to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. Supporting Tools: A return spring is used in conjunction with the handbrake. When the handbrake is engaged, the spring is stretched; when released, the spring returns to its original length. With prolonged use, the spring may also undergo corresponding deformation.
