The invention provides a crawler-type vehicle hybrid suspension device which comprises a balance elbow, a torsion shaft, a hydro-pneumatic spring, a damping limiter and a pull arm, the balance elbow, the torsion shaft and a vehicle body are connected into a whole, axial limiting is achieved at the same time, and the device serves as an elastic element to play a role in buffering and absorbing vibration. The hydro-pneumatic spring is used as an elastic element to buffer and absorb vibration and achieve suspension rigid locking, the balance elbow is used for connecting a loading wheel and a vehicle body, rotation is achieved through a needle bearing, axial limiting is achieved through a plurality of steel balls, and meanwhile elastic supporting and buffering force is provided for the vehicle by being connected with a torsion bar and a suspension elastic element. The damping limiter is used for limiting the travel of the loading wheel, absorbing buffering energy and assisting in improving the energy absorbing capacity of the suspension device. Under the restrictions of space, structure and the like, the device can achieve good whole vehicle suspension performance, meets the application requirement of the wide bearing range of the crawler-type vehicle, and has the advantages of being easy to engineer, high in adaptability and the like.
