Abstract
The invention discloses an automobile and a suspension offset frequency adjustment device. The suspension offset frequency adjustment device comprises a first mounting base, an elastic part and a drive device, wherein the suspension offset frequency and the suspension rigidity are in direct proportion, the suspension rigidity and the total rigidity of a damping spring and the elastic part are in direction proportion, and the rigidity and the length of the elastic part are in inverse proportion. When the drive device controls the elastic part to retract, the total rigidity of the damping spring and the elastic part is increased, accordingly, the suspension rigidity is increased, the suspension offset frequency is increased, the vertical acceleration which a passenger senses in the running process of the automobile is increased, and car sickness becomes more serious. When the drive device controls the elastic part to extend, the total rigidity of the damping spring and the elastic part is reduced, accordingly, the suspension rigidity is reduced, the suspension offset frequency is reduced, the vertical acceleration which the passenger senses in the running process of the automobile is reduced, and car sickness is relieved and even disappears. According to the suspension offset frequency adjustment device, the suspension offset frequency can be adjusted according to demands of the passenger, and accordingly, car sickness of the passenger in the automobile is relieved.
