A end, the air inlet simultaneously of D end, B end, the exhaust simultaneously of C end, small piston 9 remains on left side original position, and big piston 11 moves right, because big piston 11 is the cylinder barrel of the small piston 9 of little cylinder, moves right so drive stingy cylinder integral body simultaneously.At this moment, neutral position in the middle of gear returns to.
D. advance right retaining:
A end, the air inlet simultaneously of C end, B end, the exhaust simultaneously of D end, big piston 11 keeps right side original position motionless, and small piston 9 moves right, and corresponding Transmission gear enters right gear.Wherein the principles such as buffering in the moving process are with advancing left side shelves.
E. return neutral gear left:
B end, the air inlet simultaneously of C end, A end, the exhaust simultaneously of D end, small piston 9 keeps right position motionless, and big piston 11 is moved to the left, because big piston 11 is the cylinder barrel of the small piston 9 of little cylinder, is moved to the left so drive stingy cylinder integral body simultaneously.At this moment, neutral position in the middle of gear returns to.
So far, finish gear shift circulation.Constantly repeat said process, can carry out the gear shift fatigue test speed changer.When the different operation program of establishment, then can move on request.
The various situations of above-mentioned gear shift can be summed up as following table.
| The A end | The B end | The C end | The D end | |
| Original neutral | - | + | + | - |
| Advance left side shelves | - | + | - | + |
| Return neutral to the right | + | - | - | + |
