The invention relates to the technical field of vehicle engineering, and particularly discloses a single trailing arm suspension, an angle module structure and a vehicle, the single trailing arm suspension comprises a trailing arm speed reduction assembly and a steering knuckle, the trailing arm speed reduction assembly is connected with a vehicle frame through a shock absorber assembly, and the axis extension line of the shock absorber assembly is parallel to the ZX plane of the vehicle frame; a speed reducing mechanism is arranged in the trailing arm speed reducing assembly, an output shaft of the speed reducing mechanism is rotationally connected with the trailing arm speed reducing assembly, the axis extension line of the output shaft of the speed reducing mechanism is perpendicular to the ground, one end of the steering knuckle is fixedly connected with the output shaft of the speed reducing mechanism, and the other end of the steering knuckle is fixedly connected with the wheel assembly. The speed reducing mechanism is arranged in the trailing arm speed reducing assembly to drive the steering knuckle to rotate, the wheel assembly is driven to steer, suspension and steering decoupling is achieved, meanwhile, the wheel assembly is along the ZX plane of the frame all the time when jumping, and therefore the rotation angle of the projection of the wheel assembly on the XY plane of the frame in the steering process is consistent with the target rotation angle, and steering precision is guaranteed.
