For Chongqing Changan SC1010 models for design and the new pressure ring, so that it increases with the increase of torque transmission friction disc friction torque, and opening of V groove on the pressure ring, and planetary gear shaft end V type inclined surfaces with, to realize the compression of frictional element and improve the differential service life; in between the friction element and the differential case the dish spring as often the role of elastic element. This is due to the axial size is small, with the characteristics of good elastic deformation. In the case of meeting the locking coefficient, the structure has the advantages of small size, few parts, easy to realize electronic control, and convenient manufacture and subsequent development.
