The invention discloses a combined hydraulic suspension trailer having an auxiliary driving function. As a motor arranged at the end part of an axle has a free wheel function, the motor can be passively rotated (free wheel function) at a high speed without being damaged under the condition without pressure oil, and can generate driving force to drive a hub to rotate under the condition with the pressure oil; when the combined hydraulic suspension trailer moves on a flat ground or moves uphill in a condition that traction force provided by a traction vehicle is sufficient, an axle having an auxiliary driving functiononly bears the load and provides no traction just like a standard axle of a combined hydraulic suspension trailer; and when the combined hydraulic suspension trailer moves uphill and the traction force provided by the tractor is insufficient, the axle having the auxiliary driving function can provide certain traction to assist the tractor. No tractor needs to be added, so that the transportation cost can be reduced.
