AI Technical Summary
The manual transmissions of existing electric tricycles suffer from problems such as difficulty in shifting gears, severe wear, shifting jerks, complex operation, and efficiency loss, especially during the transition between high and low gears, which can easily cause wear and efficiency loss.
The system employs a two-speed electric drive system with manual and automatic synchronous switching. By adding an overrunning clutch and a synchronizing ring, it achieves smooth switching between high and low speeds. The overrunning clutch ensures stable power transmission during gear shifting, while the synchronizing ring ensures synchronized speeds and avoids wear caused by direct contact.
It enables easy gear shifting, reduces shift shock and wear, improves driving experience and comfort, and optimizes transmission efficiency, reducing maintenance costs and frequency.
