The invention discloses a suspension device, a control method of the suspension device, a vehicle and engineering machinery. The suspension device comprises an upper cross beam, a lower cross beam, a watt connecting rod mechanism, an automatic posture adjusting system and a vibration reduction system. One end of a connecting rod A in the Watt connecting rod mechanism is connected with an upper cross beam, the other end of the connecting rod A is connected with a hydraulic cylinder A, one end of a connecting rod B is connected with the upper cross beam, and the other end of the connecting rod B is connected with a hydraulic cylinder B; the posture autonomous adjusting system is connected with the hydraulic cylinder A and the hydraulic cylinder B and used for controlling the hydraulic cylinder A and the hydraulic cylinder B to stretch out and draw back according to the cab inclination angle so as to realize autonomous adjustment of the cab inclination angle; the vibration reduction system is connected with the hydraulic cylinder A and the hydraulic cylinder B and used for adjusting damping and rigidity of the hydraulic cylinder A and the hydraulic cylinder B so as to achieve active vibration reduction of the cab. According to the invention, cab swing stable control, inclination attitude control and active vibration reduction can be realized at the same time, and the vibration comfort of the cab is improved.
