An air cushion system of a bus is provided to remove leaning of a large type bus frame to one side, which is generated at the time of forward or backward movement, and to secure safe driving. An air cushion system of a bus comprises a rotational rod(10), a hydraulic cylinders(20,120), an airbags(25,125), front wheels(30) and an air injection pump. The rotational rod is coupled to a spare tire(11), and rotated around hinges(12,112). The hydraulic cylinder is coupled to an end of the rotational rod. The airbag is coupled to height adjusting pistons(22,122) communicated with the opposite part to communication pipes(21,121) communicated with the hydraulic cylinder. The front wheels are connected to ends of interlocking pistons(26,126) of the airbag. The air injection pump is linked with sensors(41,141) for measuring distance between the airbag and the front wheels, and injects or deflates air inside/from the airbag. |
