The invention discloses an automobile power assembly suspension. An installing arm of a support arm is a cylindrical installing arm; an installing cavity is arranged in an installing main spring which is arranged on a rubber main spring; the installing arm is assembled in the installing cavity; an anti-rotation convex rib is arranged on the outer wall of the installing arm along the axial direction; an anti-rotation clamp groove matched with the anti-rotation convex rib is arranged in the installing cavity; a plurality of anti-slip convex rings are arranged in parallel on the installing arm at intervals; a plurality of convex ribs in separated arrangement along the axial direction are arranged in the installing cavity in a surrounding way; the installing arm is inserted into the installing cavity through the anti-rotation convex ribs along the anti-rotation clamp grooves, and the anti-slip convex rings are tightly matched with the convex ribs. The automobile power assembly suspension has the advantages that the stress on a support arm periphery assembly of the cylindrical installing arm is more stable than that of the installing arm in other shapes; when the support arm receives the torque force, the anti-rotation convex ribs are inserted into the anti-rotation clamp grooves, so that the installing arm cannot rotate, and the effects of positioning the support arm and preventing the support arm from rotating are achieved; when the support arm receives the pull force action, the anti-slip convex rings are tightly clamped with the convex ribs, and the outward pulling of the installing arm through being stressed is prevented, and the support arm is prevented from being disengaged from the rubber main spring.
