1. The role of the brake hose
The air brake hose is an indispensable part of the vehicle braking system. It connects the braking system and the wheel brakes and is responsible for transmitting the braking medium (such as compressed air) to generate braking force. Therefore, the performance of the brake hose directly affects the overall effect of the vehicle braking system.
2. Factors affecting braking performance
Aging and wear: Brake hoses used for a long time or in harsh environments will age and wear, resulting in poor pressure transmission or leakage inside the hose, which in turn affects the braking effect. For example, rubber aging may cause the hose to harden and crack, reducing its ability to transmit braking media.
Internal structural damage: Under the action of long-term bumps, vibrations, corrosion, etc., the internal braided layer of the brake hose may be damaged, cracked, bulged, etc. This will not only reduce the pressure resistance of the hose, but may also cause leakage of the brake medium, seriously affecting the braking performance.
The influence of rubber material: Brake hoses are usually made of rubber, and rubber products will expand and deform to a certain extent under high temperature and high pressure. This deformation may cause the braking force transmitted by the brake hose to decrease, thereby extending the braking distance.
3. Specific impact analysis
Extended braking distance: When there is a problem with the brake hose, the poor transmission or leakage of the brake medium will cause the pressure in the brake cylinder to decrease, which will reduce the moving distance of the brake bellows and reduce the friction between the brake shoe and the wheel. This will to a longer braking distance and increase driving risks.
Unstable braking: Damage to the internal structure of the brake hose or deformation of the rubber material may cause unstable braking force during braking. When the driver steps on the brake pedal, he may feel abnormal conditions such as longer brake pedal travel, weakened braking force, or fluctuating braking force, which seriously affects the driving experience and driving safety.
