What Causes the Locking Phenomenon in Electric Tricycle Brakes?
2 Answers
Tricycle brake locking indicates that the brakes are too tight. Here is relevant information: Drum brakes: Two semi-circular brake shoes are installed inside the wheel hub. The "lever principle" is used to push the brake shoes, causing them to come into contact with the inner surface of the hub and generate friction. This produces sufficient friction to reduce the wheel's rotation speed, achieving the braking effect. Disc brakes: A brake caliper controls two brake pads to clamp the brake disc on the wheel. When the brake pads clamp the disc, friction is generated between them to reduce the wheel's rotation speed, allowing the vehicle to slow down or stop. ABS Anti-lock Braking System: Most modern vehicles are equipped with an ABS anti-lock braking system, which ensures that the vehicle maintains directional control while braking without skidding or sliding. The principle of ABS is equivalent to manually creating intermittent braking, but this intermittent braking technology operates at a higher frequency and faster speed. Therefore, when a vehicle with ABS encounters an emergency, the brakes must be firmly pressed down in one motion.
I've been driving an electric tricycle for transportation for five or six years and often encounter brake lock-up issues. There are several main reasons: First, too much dust or debris accumulates on the brake pads, jamming them and preventing rotation; second, the brake fluid hasn't been changed for too long, becoming as dirty as muddy water, clogging the oil passages and preventing the pistons from retracting; third, the vehicle operates in damp environments for extended periods, causing the brake discs to rust and seize, sticking as soon as you press the pedal; another possibility is that the adjustment is too tight, with incorrect tension, causing the brakes to lock up with even slight pressure. This issue is particularly annoying, especially when the brakes suddenly lock up on a downhill slope, making the tires smoke and giving me a scare. I recommend cleaning the brake components more frequently, changing the fluid every three months, and drying the brakes promptly after rainy days to avoid unnecessary hassle and work delays.
