A common separation mode of the dynamic friction plate and the static friction plate is natural separation, and a power-assisted separation mechanism is not arranged between the plates. A common power-assisted separation method of the dynamic friction plate and the static friction plate is to install a spiral spring piece between the static friction plates, and fix the spiral spring piece by a bolt or a cylindrical pin penetrating through the spring and the static friction plate; when the vehicle is braked, the spring elasticity pushes the static friction plate away along the axial direction so as to increase the distance between the plates. A common assistance separation method of a dynamic friction plate and a static friction plate is to install a separate disc spring between the static friction plates and fix the disc spring and the static friction plates by bolts or cylindrical pins penetrating through the disc spring and the static friction plates; when the vehicle is braked, the spring elasticity pushes the static friction plate away along the axial direction so as to increase the distance between the plates.
