Abstract：In order to solve the problems of limited slip limiting ability,complex configuration and diffi-cult manufacturing of inter-axle limited slip differentials,a new design scheme of inter-axle limited slip differ-entials with face gears is proposed.By analyzing the configuration principle and motion characteristics of the dif-ferential,the mechanical balance equation and locking coefficient theoretical model of the differential are estab-lished.Based on the machining principle of face gears and the working characteristics of differentials,the 3D en-tity model and Adams virtual prototype are built.The multi-body dynamics is analyzed by Adams simulation software.The results show that the locking ratio of differentials to the front and rear axles can reach 6.5 and 5.When travelling on a good road,the output torque of the front and rear axles is basically consistent with the pre-set torque distribution ratio of 40:60.When travelling on the double-adhesion-coefficient road surface,the slip-ping axle can be locked quickly,more torque can be distributed to the non-slipping axle,and the torque distri-bution to the front and rear axles can reach 73％and 79％respectively.The results verify the feasibility of the in-ter-axle limited slip differential with face gears,and provide a basis for its design and application.
