AI Technical Summary
Existing wet clutches are prone to damping orifice jamming when the friction elements separate, resulting in incomplete separation of the friction elements, poor lubrication, high friction element temperature, and easy thermal warping failure.
Pressure relief oil holes and lubrication oil holes are provided on the cylinder liner. The movement of the piston enables the oil to self-depressurize and self-lubricate. A reset assembly is provided between the piston and the friction element. High-pressure oil drives the piston to squeeze the friction element to transmit power, and pressure is quickly relieved through the pressure relief oil hole when the clutch is disengaged.
It achieves rapid separation and self-lubrication of friction elements, reduces cylinder liner weight, improves lubrication effect, avoids thermal warpage failure of friction elements, and increases the power density of the integrated transmission device.
