Claims

A trailer chassis structure having two I beams arranged side by side, and a basic frame consisting of a transverse reinforcement frame and a transverse reinforcement frame intersecting therebetween and a front and rear bolsty, the gap being greater than the maximum distance between the I beams on both sides Has a slider 21 isolated from each other, and the slider 21 has a cross-sectional quadrangular transverse metal tube 61, 62, 63 which cross-connects the brackets 14, 15, 16 downwardly suspended therefrom. And a rear assembly supported by the slide assembly, wherein the rear bolster (70) is fixed to the rear top of the slider assembly which is slid into the base frame.

2. The slider 21 according to claim 1, wherein the slider 21 has a bottom portion 22 so that the bottom surface of the I beam 10 slides on the top surface of the bottom portion 22, and on the vertical sidewall of the slider 21, An extension trailer chassis structure in which a cross-section C-shaped bracket (39) having holes (31, 32) is welded to limit the moving distance of the slider and to prevent the I beam (10) from escaping.

The position lock according to claim 1 or 2, wherein the inner frame is composed of three links (85,86,95), one connecting link (87), and a return spring (89) inside the I beam (10). Under the slider member 23 which is provided and which slides on the outer side of the I beam 10, the positioning mechanism which consists of flap members 56 and 57 and the stopper 55 is provided in the arrow. Extendable trailer chassis structure.

In a trailer chassis structure having a base frame composed of two I beams arranged side by side, a transverse reinforcement frame transversely connected therebetween, and a front and rear bolsters fixed respectively to the front and rear upper ends of the I beams, the rectangular cylindrical slider member (10) and two sliders (24) composed of inverted L-shaped brackets (11) welded to the inner wall of the slider member (12) and disposed below both side I beams (10); An extendable trailer chassis structure comprising a slider assembly comprised of a plurality of cross-sectional quadrilateral metal tubs (60, 61, 62, 63) extending transversely therebetween.

5. The lifting surface preventing bracket 40 of the I beam 10 is provided on the outer surface of the reverse L-shaped bracket 11, wherein the rectangular cylindrical slider member 12 and the reverse L-shaped bracket 11 are disposed. An extendable trailer chassis structure characterized in that a sleeve (80) is installed to penetrate through the position fixing pin (52) in the sleeve (80).

6. A bracket according to claim 4 or 5, wherein the bracket is formed on a link 35 and a transverse metal tube 60 pivotally connected to a downwardly inclined bracket 34 below the rectangular cylindrical slider member 12. Supported by a link 33 pivotably connected to 32 and installed along the rail R to the pin 36 so as to be grounded or received when the slider assembly is extended or stretched so that it can be accommodated. An extendable trailer chassis structure comprising an auxiliary wheel assembly comprising an auxiliary wheel and an auxiliary axle.
