SU396284A1 - FRAME FOR DOUBLE TRACTOR TRAILERS - Google Patents

Description

one

This invention relates to a transnort.

Frames for biaxial tractor trailers are known, comprising a sill beam of telescopically articulated tubes, one of which is connected to the front and the other to the rear axle of the wheels.

The purpose of the invention is to simplify the design, reduce metal consumption and increase durability.

For this, the proposed frame is provided with a torsion built inside the telescopically articulated sill tube, with the ends of the torsion being rigidly connected.

The drawing shows the described frame.

Torspop 1 (elastic element) of the frame is installed in the front 2 and rear 3 telescopically articulated pipes forming the spinal beam 4. The front pipe with braces 5 is attached to the beam 6 of the front axle of the trailer, and the rear pipe with braces 7 to the beam 8 of the rear axle of the trailer. The torsion is fixed at one end in the pipe 2 through the liner 9, and the other in the pipe 3 through the liner 10.

When moving over the obstacle, beams 6} iS are warped relative to each other, rotating the pipe 2 in the pipe 3, while the torsion bar 1 receives a swiveling curl on a certain length.

The torsion properties of the torsion a / provide the smoothing of stresses arising in the welded frame joints during torsion of the front and rear axles.

Frame for two-axle tractor trailers,

5 containing a spinal beam of telescopically connected pipes, one of which is connected to the front and the other to the rear wheel axle, characterized in that, in order to simplify the design, reduce the metal intensity and increase reliability, it is equipped with a torsnop embedded inside telescopically articulated spinal beam pipes, with the ends of the torspon being rigidly connected to the pipes.
