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 pulled, resulting in different levels of braking force applied under different circumstances. Below is some relevant information about handbrakes: 1. Principle: The professional term for a handbrake is an auxiliary brake. Unlike the main brake system, it uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use can reduce its effectiveness and increase the handbrake's travel distance. 2. Supporting Components: 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 experience corresponding deformation.
