The invention discloses a durability test bed for a non-independent suspension. The device comprises a base and two portal frames fixed on the base, wherein a cross beam of the portal frame is fixedlyconnected with the top of an actuator, a bottom of the actuator is fixedly connected with a top part of a loading tool, one side of the left loading tool is fixedly connected with a hub of a to-be-tested non-independent suspension through a bolt, and the other side of the loading tool is in sliding fit with a limiting column in the vertical direction. The durability test bed is reasonable in structural design and wide in application range, effectively simulates actual working conditions and reduces the test expenditure, and shortens a test period. 一种非独立悬架耐久性试验台架，包括：底座及其上固定的两个龙门架，所述龙门架的横梁与作动器的顶部固定连接，所述作动器的底部与加载工装的顶部固定连接，所述左加载工装的一侧通过螺栓与待测试非独立悬架的轮毂固定连接，所述加载工装的另一侧与限位柱延竖直方向滑动配合。本设计不仅本设计结构设计合理，有效模拟实际工况，适用范围广，而且有效降低试验经费，缩短试验周期。
