The category of the special automobiles in the market is very numerous currently, so the category of the power take-offs are also numerous. The ways of installment of these power take-offs are all different and the positions where they will be fixed are also different,so the performance of these power take-off are all different.Therefore,to design a kind of power take-off with high quality and easy to operate is necessary.What this paper study is a kind of engine power take-off.Its advantage is the tightly packed structure,long time to keep on working, and it is free from the interference of the automobile clutch.As long as the machine is working, in spite of the clutch is coalesced or n
