The invention discloses a torsion resistant pull rod of a power assembly. The torsion resistant pull rod comprises a pull rod bracket, a large liner bushing and a small liner bushing, wherein the large liner bushing and the small liner bushing are respectively arranged at two ends of the pull rod bracket; the large liner bushing comprises a large liner bushing inner pipe; and the small liner bushing comprises a small liner bushing inner pipe. The torsion resistant pull rod is characterized in that the upper surface of the pull rod bracket is a flat end surface; the central axis of the small liner bushing inner pipe is parallel to the upper surface of the pull rod bracket; an oblique obtuse angle is formed between the central axis of the large liner bushing inner pipe and the upper surface of the pull rod bracket; when one end of the pull rod bracket is connected with the power assembly through the small liner bushing, an oblique acute angle is formed between the upper surface of the pull rod bracket and a level surface; and the difference between the oblique obtuse angle and the oblique acute angle is 90 degrees. The torsion resistant pull rod disclosed by the invention has the advantages that after the pull rod bracket of the torsion resistant pull rod is mounted in a preset angle, the upper surface or the lower surface of the large liner bushing inner pipe can be mounted on a vehicle body or a sub vehicle frame in a flat clinging manner, so that the mounting stability and the whole using stability of the torsion resistant pull rod are guaranteed.
