Problems solved by technology

[0003] However, the frames of traditional semi-trailers are mostly directly welded with I-shaped steel or fixed with bolts. Most of the components of the frame are directly fixed in twos and vertically. The force is uneven, and it is not easy to repair and maintain after being damaged during use

Abstract

The invention relates to the technical field of automobile accessories, in particular to a riveting type semitrailer frame which comprises a cold bending longitudinal beam rod, a front cross beam structure, a first 100mmW scale structure, a second 100mmW scale structure, a third 120mmW scale structure, traction base structures, a side beam structure and third diagonal draw bars. Two bent longitudinal beam rods are symmetrically arranged on the edge beam structure, the traction base structures used for traction are fixed to the bent longitudinal beam rods, the traction base structures are connected to front cross beam structures used for reinforcement and arranged on the bent longitudinal beam rods, and the front cross beam structures are fixed to the edge beam structure. The third diagonal draw bars used for reinforcement are arranged between the edge beam structures and the bent longitudinal beam rods, triangles are formed among the edge beam structures, the bent longitudinal beam rods and the third diagonal draw bars, so that the structure is more stable, meanwhile, the edge beam structures and the front cross beam structures on the bent longitudinal beam rods are of a sectional type, the structure is more convenient to install, and the requirement for materials is lowered. Meanwhile, the connection of the traction base structures is firmer.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a riveted semi-trailer frame. Background technique [0002] Cars are the most important means of transportation and play an irreplaceable role in people's daily lives; semi-trailers are axles placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded), and equipped with horizontal and vertical The force is transmitted to the trailer of the coupling device of the tractor; the semi-trailer is generally a three-axle semi-trailer, and its types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, low-bed semi-trailers and many other types; through the traction pin A heavy-duty transport vehicle connected to the head of the semi-trailer. [0003] However, the frames of traditional semi-trailers are mostly directly welded with I-shaped steel or fixed with bolts. Most of the components of the frame are directly fixed in twos...
