Described rubber spring is that the rubber tube that cast rubber forms between center shaft and outer metal cylinder consists of.

Working process of the present invention and principle are:

Turn negative thread swing arm, rubber spring is screwed or loosen, and then the rigidity that makes rubber spring increases or reduces, because the center shaft of the front lower end of two body cradles and rubber spring type levitation device is fixed together, and then can adjust as required the hoverheight of seat.

The swivel base setting of the upper end of permanent seat is in order to adapt to rubber spring screwing or loosen along the circular arc direction.

The invention has the beneficial effects as follows:

1, simple in structure, cost is low.

2, the hoverheight of seat is easy to adjust quick.

3, the body weight setting range of suitable chaufeur is large.
