Abstract: To better promote the development of advanced axle technology, the foreign development status of modular independent suspension axle and the domestic product development and technology exploration are described. The characteristics of modular independent suspension axle, such as strong military background, product serialisation, unified guide mechanism and spring nonlinearity, are summarised. The main technical development directions of modular independent suspension axle, driveable and controllable, wheel jump large stroke and suitable power distribution drive are pointed out, puts forward the thinking of technical route, which has certain positive significance for the further development of domestic modular independent suspension axle technology.
