1results about How to "Shift quickly" patented technology

This utility model relates to the field of quick manual gear shifting technology, and discloses a quick manual gear shifting mechanism, including a mounting plate, a support shaft, a shift fork shaft, a shift fork gear, a two-speed gear, and a shift drive assembly. The support shaft and the shift fork shaft are fixed to the mounting plate. The shift fork gear is slidably connected to the support shaft via a spline. The shift drive assembly includes a shift fork seat, a shift fork block, and a toothed shift fork, which is slidably connected to the shift fork shaft and is used to drive the shift fork gear to move axially, selectively engaging with the two-speed gear rotatably connected to the support shaft. The key feature is the inclusion of a self-locking positioning device. This device, through the cooperation of a groove on the shift fork shaft and a steel ball, mechanically locks the shift drive assembly after the gear is engaged, stably maintaining the engagement position. This utility model solves the problems of unstable engagement positioning and easy automatic disengagement due to vibration in existing gear shifting mechanisms, achieving the beneficial effects of quick shifting, accurate positioning, and stable and reliable engagement.
