The invention provides a four-joint hydraulically-driven robot leg, and aims at solving the problems that an existing hydraulically-driven robot is limited in motion ability and poor in terrain adaptability. The four-joint hydraulically-driven robot leg is structurally composed of a hip joint assembly, a coxa assembly, a thigh assembly, a shank assembly, a thigh hydraulic cylinder and a shank hydraulic cylinder. The hip joint assembly is composed of a horizontal swing hydraulic motor, a flange output shaft, a coupler, a flat key, a main shaft, a hip joint bearing, a bearing seat, a body rack, a thrust bearing and a rotating seat. The coxa assembly is composed of a vertical swing hydraulic motor, a staggered coxa, a coxa trunnion, a coxa bearing and a coxa hydraulic cylinder lug. The thigh assembly is composed of a thigh, a thigh hydraulic cylinder lug, a thigh trunnion and a thigh bearing. The shank assembly is composed of an upper shank shell, a lower shank shell, a linear bearing, a damping spring, a force sensor, a shank trunk and a foot end. The four-joint hydraulically-driven robot leg is flexible in motion and capable of completing complex motion, and has greatly enhanced terrain adaptability, meanwhile, the design of the novel and reliable high-heavy-load robot motion joint is provided, which has a certain application prospect.
