Is pulling up the gear lever on an electric tricycle for high gear or low gear?
2 Answers
The so-called climbing gear on an electric tricycle is actually the low gear. It achieves the purpose of climbing by relying purely on mechanical deceleration, rather than by increasing the engine power. Electric vehicle controllers are equipped with current-limiting protection functions, which can protect the motor from burning out, the circuit from being damaged, and the battery from over-discharging. Here is more detailed information: Content 1: The high-low gear lever controls a cable, which in turn controls the shift fork. Since the shift fork lacks a positioning device, the cable requires additional positioning. When the gear lever is shifted to the low gear, the large gear on the second shaft meshes with the small gear on the first shaft, and the small gear on the second shaft drives the differential. Content 2: At this time, the medium-sized gear on the second shaft idles on the second shaft, rotating faster than the large gear. This is the structural principle of the climbing gear on a tricycle.
I've been delivering packages with an electric tricycle in a small town for ten years. Pulling up shifts to a lower gear, which is commonly used when climbing steep slopes or carrying heavy loads to reduce speed but increase torque. When I first started, I always got it backwards and nearly stalled the vehicle. Later, my mentor taught me: pulling up is like slowing down after braking, while stepping down is for accelerating and shifting to a higher gear. The transmission of an electric tricycle is simple, similar to that of an old-fashioned motorcycle, and requires gentle and smooth operation. Jerking it abruptly can easily wear out the shift cable or gears, leading to strange noises over time. Regularly check the connection points of the shift lever and add some lubricant to keep it smooth. Higher gears are suitable for flat roads to save power, but when encountering bumps or turns, you must downshift to ensure safety. I always remind beginners to practice more in real scenarios, such as trying a section of uphill road to get familiar with the feel, rather than just theorizing to avoid trouble.
