While maintaining the original weight,the ratchet engagement area with the "same number of teeth" has increased by approximately 20%, significantly improving the load-bearing capacity of the planetary gears and making power transmission more stable and reliable. In addition, the larger engagement area provides higher redundancy for the ratchet engagement state, significantly improving operational stability. This guiding design allows the pawl to engage with the gear more smoothly and precisely, resulting in a faster engagement process, significantly reduced backlash, and a more direct power response.
