Clutch for easy shifting

During the driving process, different gearbox positions are often used to adapt to changing driving conditions. If there is no clutch to temporarily separate the engine from the transmission, the meshing gears in the transmission will not be removed due to the load, and the pressure between the meshing surfaces will be large and difficult to separate. The other gear to be meshed is difficult to engage due to the unequal circumferential speed of the two. Even if it is forcibly engaged, it will cause a large tooth end impact and easily damage the machine.
When the engine and the transmission are temporarily separated by the clutch and then shifted, the original pair of gears are removed by the load, and the pressure between the meshing surfaces is greatly reduced, so that it is easy to separate. The other pair of gears to be engaged, because the driving gear is separated from the engine, the moment of inertia is small, and the appropriate shifting action can make the circumferential speeds of the gears to be meshed equal or nearly equal, thereby avoiding or reducing the impact between the gears.
