When the fluid of lower pressure enters the moment of cushioning oil pocket, on piston form less thrust overcome Compress Spring elastic force promote piston move to left, and with less pressure-acting in friction plate, between internal toothed friction plate and external tooth friction plate, transmit less moment of torsion and produce relative sliding, under driving link rotating speed invariant state, driven member rotating speed slowly increases, clutch smooth and steady combination.
When piston moves to left, the hydraulic fluid chamber inner fluid pressure forming between rotating hydraulic cylinder and piston also slowly raises, thrust on piston also increases gradually, pressure between internal toothed friction plate and external tooth friction plate increases gradually, frictional force increases, relative sliding is reduced to synchronous rotary gradually, and the power of clutch transmission is increased to maximum value gradually.
When fluid loses pressure, hydraulic fluid chamber inner fluid returns through in-line, and piston returns to initial position under the elastic force effect of spring, and the fluid in draining chamber returns to oil sump through one-way valve fast, and internal toothed friction plate separates completely with external tooth friction plate, and clutch is transferring power not.
The variation of oil liquid pressure size is regulated automatically by hydraulic control system.
Therefore, the mechanical gear of a kind of available buffer transmission that the utility model provides, has compact structure, and reliability is high, can realize buffering gear shift continuously, easy to operate.
