The brake foot valve plays a key role in emergency braking response. Its design and working principle ensure that braking can be implemented quickly and reliably in emergency situations.
Emergency braking signal acquisition:
The brake foot valve is first connected to the brake pedal to obtain the emergency braking signal from the driver. This signal is generated when the driver presses the brake pedal suddenly and hard, indicating the need for immediate braking.
Brake fluid pressure increase:
Once an emergency braking signal is obtained, the brake foot valve rapidly increases the pressure of the brake fluid. This process usually involves the control of a proportional valve, which increases the pressure in the hydraulic transmission system by adjusting the position of the spool. This can quickly increase the working pressure of the braking system in a short period of time.
Fast response proportional valve control:
The proportional valve inside the brake foot valve plays a key role in emergency braking situations. The design of the proportional valve allows for rapid and accurate adjustment of brake fluid flow and pressure. In emergency braking response, the proportional valve will quickly open to ensure that the brake fluid enters the braking system at a higher pressure, thereby quickly improving the braking effect.
Quick closing valve core:
In order to enhance the rapid response of the braking system, the spool design of the brake foot valve allows it to close quickly. This prevents brake fluid from stagnating in the brake system and ensures that the brake system can take effect immediately in the event of emergency braking.
Dynamic adjustment of hydraulic system:
Emergency braking response involves more than just increasing brake pressure and requires dynamic adjustments to the hydraulic system. The brake foot valve controls the flow of fluid in the hydraulic system to ensure the balance of braking force in emergency braking situations and prevent the vehicle from losing control due to too sudden braking.
