Reinforcing structure of traction seat of semi-trailer

Abstract

The invention relates to the technical field of semi-trailer fifth wheel, and discloses a semi-trailer fifth wheel strengthening structure, including a base, the upper end of the base is fixedly connected to the same base plate through a plurality of damping springs, and the upper end of the base plate is fixedly connected to There is a support seat, the upper end of the support seat is fixedly connected with a sleeve, and a pin shaft is rotatably sleeved in the sleeve tube, and both ends of the pin shaft are fixedly connected with a fixed seat, and the upper ends of the two fixed seats pass through A plurality of connecting rods are fixedly connected with the same saddle body, the upper and lower ends of the plurality of shock absorbing springs are fixedly connected with mounting plates, and the upper end of the base and the lower end of the bottom plate are provided with mounting plates corresponding to the mounting plates. groove. The reinforced structure of the traction seat of the semi-trailer has the advantages of being able to quickly disassemble and assemble multiple shock absorbing springs and being easy 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
