WIPO Patent Application WO/2023/039927
Kind Code:
A1
Abstract:
A rear independent suspension system having two-stage stiffness, comprising an auxiliary frame (1), an upper front connecting rod assembly (2), a steering knuckle (3), a lower swing arm assembly (4), an upper rear connecting rod assembly (5), a spiral spring shock absorber assembly (6), an auxiliary spring (7), and a hub (8). Two-stage stiffness of the independent suspension system is realized, so that an elastic element presents certain nonlinearity, and the bearing capacity of the independent suspension is improved; moreover, the rear independent suspension system is simple in structure, economical, practical, firm, durable, small in occupied space, and convenient to use and maintain.
