Mainstream braking systems for electric tricycles

1. Mechanical Drum Brakes: These brakes rely on a cable to pull the brake shoes outwards, creating friction against the inner wall of the brake drum. The springs automatically return the shoes to their original position after the cable is released. They are simple in structure, low in cost, and have good dust resistance, making them suitable for low-speed, short-distance commuter vehicles. However, they are prone to heat fade on long downhill sections, requiring regular adjustment of the brake cable tension.

2. Hydraulic Disc Brakes (Oil Brakes): These brakes transmit pressure through brake fluid, pushing the caliper to clamp the brake disc and achieve braking. They offer over 30% higher braking force than mechanical brakes, dissipate heat quickly, have less heat fade, and shorter braking distances, making them the preferred choice for heavy-duty, high-speed vehicles.

3. Electronic Brake Assist: When the brake lever is squeezed, the brake switch triggers a signal, and the controller causes the motor to generate a back electromotive force for gentle deceleration. Simultaneously, it cuts off power and illuminates the brake lights. It typically works in conjunction with hydraulic/mechanical brakes to achieve a smoother braking effect.

4. Linked Braking Layout: The common high-performance configuration is "front disc and rear drum," where the front wheels bear 70% of the braking load and use disc brakes to ensure safety, while the rear wheels use drum brakes to control costs. Heavy-duty vehicles are often equipped with "one-foot three-brake," where one foot of the brake simultaneously links all three wheels, and is also equipped with an independent mechanical handbrake as a second layer of safety.
