Semitrailer traction seat reinforcing structure

Abstract

The invention relates to the technical field of semitrailer traction seats, and discloses a semitrailer traction seat reinforcing structure. The structure comprises a base, and the upper end of the base is fixedly connected with the same bottom plate through a plurality of damping springs. The upper end of the bottom plate is fixedly connected with a supporting seat. The upper end of the supporting seat is fixedly connected with a sleeve. A pin shaft is rotationally sleeved in the sleeve. Fixing seats are fixedly connected to the two ends of the pin shaft correspondingly. The upper ends of thetwo fixing seats are fixedly connected with the same saddle body through a plurality of connecting rods. Mounting plates are fixedly connected to the upper ends and the lower ends of the multiple damping springs correspondingly, and mounting grooves correspondingly connected with the mounting plates in a clamped mode are formed in the upper end of the base and the lower end of the bottom plate correspondingly. The semitrailer traction seat reinforcing structure has the advantages that the plurality of damping springs can be quickly disassembled and assembled, and the semitrailer traction seatreinforcing structure is convenient to use.

Description

technical field [0001] The invention relates to the technical field of a semi-trailer fifth wheel, in particular to a strengthening structure of a semi-trailer fifth wheel. Background technique [0002] Automobile fifth wheel is a pulling part used by a truck to pull a semi-trailer. The fifth wheel of a semi-trailer includes a saddle and a support for supporting the saddle. The saddle is installed through the pin shaft of the support. On the support, at the same time, in order to reduce the wear of the shaft pin, a support sleeve made of elastic material is usually placed between the periphery of the pin shaft and the support. The traditional installation structure, due to its unreasonable structural design, often On the one hand, the shear force on the pin shaft is relatively large, which makes the pin shaft easily damaged. On the other hand, the bearing sleeve is subject to a relatively large extrusion force, which makes the bearing sleeve very easy to wear, thereby reduci...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a semi-trailer fifth wheel reinforcement structure, which has the advantages of being able to quickly disassemble and assemble multiple shock absorbing springs and is easy to use, and solves the problem that the shock absorbing springs cannot be effectively disassembled and assembled. , the spring is easily damaged during long-term use, which affects the service life, and it is not easy to replace, which makes the performance of the entire fifth wheel not strong enough, and it is not easy to use
