The working principle of the anti-lock braking system (ABS) of a tricycle is to control the adjustment of the brake pressure through a computer to prevent the wheels from locking during emergency braking, thereby ensuring the stability and safety of the vehicle. The ABS system detects the rotation speed of the wheel through a sensor. When it detects that the wheel is about to lock, it will quickly adjust the brake pressure to prevent the wheel from stopping completely. The specific process includes the following steps:
Pressure regulation: When the braking force is lower than the specified value, the pressure regulator will cut off the return oil channel, so that the pressure of the brake system increases as the brake pedal is pressed. When the wheel slip rate is detected to be higher than a certain value, the pressure regulator will cut off the inlet and return oil circuits to maintain the oil pressure. When the slip rate exceeds the specified value, the pressure regulator will open the return oil channel, reduce the return oil pressure, and store the return oil in the reservoir. This cycle is repeated to achieve brake pressure regulation.
Preventing lock: The ABS system prevents wheel lock by high-frequency braking. This point braking technology is more frequent than traditional braking and can respond quickly in emergency situations to ensure that the vehicle does not swing or skid when braking, while maintaining control of the vehicle's direction.
Multi-mode operation: ABS systems usually have multiple working modes, including boost, hold and depressurization. During braking, the system will continuously adjust the brake pressure according to the slip rate of the wheel to ensure that the wheel works within the optimal slip rate range, usually between 10%-20%. At this time, the wheel can provide sufficient braking force and maintain a certain grip.
Through these mechanisms, the ABS system can effectively prevent the three-wheeled vehicle from locking during emergency braking, improving driving safety and stability.
