The embodiment of the invention relates to a hydraulic cylinder with a high-frequency buffer device and a hydraulic suspension device. The hydraulic cylinder comprises a cylinder bottom with a single lug ring, a cylinder cover, a cylinder barrel, a piston, a piston rod and other parts. Two oil ports are formed in the side wall of the cylinder barrel and located in the two ends of the cylinder barrel respectively. The piston is contained in the cylinder barrel, and hydraulic force acts on the piston to push the piston to move in the cylinder barrel. The piston rod is connected to the piston, and hydraulic force is transmitted to the piston through the piston rod. The buffering device is installed on the cylinder barrel and used for absorbing impact force and vibration. In the buffering device, end sealing plates are arranged at the two ends of a vibration absorption cylinder body, and a vibration absorption piston and an elastic device are arranged in the vibration absorption cylinder body. The two vibration absorption pistons are respectively arranged at two ends in the vibration absorption cylinder body, and an elastic device is arranged between the two vibration absorption pistons; oil ways are arranged on the outer sides of the two vibration absorption pistons and are communicated with an inner cavity of the hydraulic cylinder and a pipeline through two oil ports; and when the hydraulic pressure is not applied, the elastic device presses the two vibration absorption pistons on the end sealing plate, and the gap between the vibration absorption pistons and the vibration absorption cylinder body is X.
