Abstract
The invention provides a three-station switch release mechanism and method. The three-station switch release mechanism comprises a pressing spring and a bracket connected with the pressing spring, wherein a release shaft and a control shaft are arranged on the side of the bracket; a shifting fork is arranged on one side, towards the release shaft, of the bracket; a front limiting swing rod is arranged on the release shaft in the axial direction; a limiting roller is arranged in the middle of the front limiting swing rod; a control swing rod is arranged on the control shaft; a gear detent swing rod is also connected onto the front limiting swing rod; a detent in contact with a gear is arranged on the gear detent swing rod. The three-station switch release mechanism is simple in structure, the detent is utilized to limit the rotation of the gear after switch-on is finished, and the condition that in a conventional three-station switch operating mechanism, after the operation of the switch-on process is finished, the whole operating mechanism is likely to be subjected to impact vibration, which is caused by the fact that energy storage and release processes appear repeatedly when a spring is pulled upwards, is avoided. Sliding is replaced by utilizing rolling to reduce friction, and the force balance is utilized to stably clamp the front limiting swing rod on the release shaft, so that the condition that a greater moment of force needs to be input to the control shaft in switch-off is prevented.
