The invention discloses a trailing arm type four-bar linkage suspension and an automobile. The trailing arm type four-bar linkage suspension comprises an automobile body, an auxiliary frame, an upper swing arm, a spring swing arm, a toe-in control arm, a steering knuckle and a trailing arm. The front end of the auxiliary frame is fixedly connected with the automobile body; the upper swing arm, the toe-in control arm and the spring swing arm are installed on the side portion of the steering knuckle in an up-down rotating mode, and the end, away from the steering knuckle, of the upper swing arm and the end, away from the steering knuckle, of the toe-in control arm are installed on the auxiliary frame in an up-down rotating mode. The end, away from the steering knuckle, of the spring swing arm is connected to the auxiliary frame in a front-back rotating mode. One end of the trailing arm is fixedly installed on the inner side of the steering knuckle, and the other end of the trailing arm is installed on the automobile body in an up-down rotating mode. The rotating central axis of the trailing arm and the automobile body is higher than the central point of the steering knuckle, so that the impact force transmitted to the automobile body from the ground through wheels is reduced, and the riding comfort is improved.
