The invention discloses a traction device for a semitrailer. The traction device comprises a traction plate and a traction pin arranged on the traction plate and used for being connected with a motor tractor. The traction device further comprises a damping device used for damping of the traction plate. The traction plate is connected with an auxiliary frame through the damping device. According to the traction device, due to the fact that the traction plate is connected with the auxiliary frame through the damping device, vibration or impact force generated by the semitrailer can be buffered through the damping device and then is transmitted to the motor tractor through the traction pin on the traction plate, and the impact force exerted on the motor tractor can be small; and in other words, the change of the driving state of the motor tractor can be extremely little or the driving state change of the motor tractor can be eliminated, and the driving comfort level of the semitrailer can be improved while the fatigue degree of a driver can be reduced. The invention further discloses the semitrailer comprising the traction device.
