And the output gear shaft 5; the left end of the input shaft 2 passes through the side plate 3 of the power take-off housing 1 and is connected with the power source, the right end of the input shaft 2 is connected with the input gear 10; the left end of the second shaft 7 is connected with the second shaft gear 8 by the key , the two-axis sliding gear 9 is sleeved; the left end of the output gear shaft 5 is keyed to connect the output shaft gear 6, and the right end passes through the power take-off housing 1 to connect with the flange 4. The input gear 10 is in selective mesh with the two-shaft slip gear 9 , and the two-shaft gear 8 is in constant mesh with the output shaft gear 6 . A piston fork shaft 12 is arranged between the two shafts 7 and the output gear shaft 5, and the left end of the piston fork shaft 12 is provided with a shift fork 13 downwards. The power take-off casing 1 is arranged in the piston chamber, and the piston chamber is fixedly arranged on the power take-off casing 1 and communicated with compressed air.
还包括润滑和冷却系统，润滑系统包括设置在取力器壳体1上的齿轮泵14，齿轮泵14与取力器壳体1的出油管连通，并与取力器壳体1顶部的进油口连通，将润滑油通过油管从底部泵入到顶部的进油口进行润滑。冷却系统包括冷却油管焊接总成11，将取力器壳体1底部的油输送到外部进行冷却后再输送进壳体内部。It also includes a lubricating and cooling system.
