In a vehicle with manual transmission, you may downshift into a lower gear as you slow down.
手动档车辆，降低车速的同时，换低至合适档位。
Change gear ratio range, in particular, using planetary transmission, the transmission ratio can be up to 100 ~ 200 (single stage), the growth rate for slow down or drive.
传动比变化范围大，特别是采用行星传动时，传动比可到100 ~ 200(单级)，适用于减速或增速传动。
The worm gear functions to slow down and increase torque. Its output shafts spur four-bar linkage by which the movement is changed from rotary to swinging.
蜗轮蜗杆机构的作用是减速增扭，其输出轴带动四连杆机构，通过四连杆机构把连续的旋转运动改变为左右摆动的运动。
