我公司装载机采用的是滚柱摩擦式超越离合器（见图１）。超越离合器的外环齿轮３与内环凸轮２同向旋转，前者快过后者时离合器接合；后者超过前者时，离合器脱开。超越离合器的这种楔紧和脱开是随着外载荷的变化而自动进行的，不需要人为控制。超越离合器的主要零件精度要求高 Our loader is a roller friction clutch (see Figure 1). The outer ring gear 3 of the overrunning clutch rotates in the same direction as the inner ring cam 2, the former is engaged faster than the latter and the latter is disengaged when the latter is exceeded. This wedge tightness and disengagement of the overrunning clutch are automatically performed as the external load changes and do not require human control. The main part of the clutch beyond the high precision requirements
