Large-horsepower wheeled tractors have good traction performance and are suitable for large farms to be equipped with wide-width farm implements for high-speed operations. Suspension originally means hanging; being concerned about, and often refers to the suspension system of an automobile. The suspension system is the general term for all force-transmitting connecting devices between the frame of an automobile and the axle or wheels. Its function is to transmit the force and torque acting between the wheels and the frame, and buffer the impact force transmitted from the uneven road surface to the frame or the body, and attenuate the vibration caused thereby, so as to ensure that the automobile can drive smoothly.
