An isolated suspension in a low-bed trailer is provided to improve driving stability by allowing front and rear axles installed in a rear end of the trailer to have isolated structure. An isolated suspension in a low-bed trailer comprises a front end bracket(3a) and a rear end bracket(3b). Two axle structures are back and forth installed in a tire mounting units of the low-bed trailer. An arm(2) is formed in an L type in the middle of the axles. The front end bracket is mounted in a front end of the arm, and the rear end bracket is mounted in a rear end of the arm. A protrusion portion(5) of the front end bracket of a rear axle is tightly inserted in an inside groove(6) of the rear end bracket of a front axle so as to be moved up and down. An air suspension device is mounted in the rear end of the arm. |
