Non-bottom-beam frame for commercial vehicle liquefied gas bottles

Abstract

The invention discloses a non-bottom-beam frame for commercial vehicle liquefied gas bottles, and relates to the field of commercial vehicles. The non-bottom-beam frame for the commercial vehicle liquefied gas bottles comprises two saddles and pull belt assemblies correspondingly and detachably connected to the two saddles, wherein an upper cross beam and a lower cross beam which are parallel to each other are correspondingly connected between the two saddles through self-locking bolts and self-locking nuts, and detachable outer arc plates are correspondingly arranged on the outer side walls of the saddles; the shapes of the upper end faces of the saddles and the outer arc plates are matched with the external diameters of the liquefied gas bottles and are positioned on the same circular arc surface, and a symmetrical anti-rotation bracket is further arranged on the middle part of the outer side wall of one of the saddles; and ventral plates are correspondingly fixed to the inner side walls of the two saddles in a riveted mode. According to the non-bottom-beam frame for the commercial vehicle liquefied gas bottles, the problems of welding deformation of the frame, difficult disassembly and assembly and radial rotation and axial movement of the liquefied gas bottles occurring in the vehicle driving process are solved, the weight and production costs of products are further reduced by more than 30%, and the non-bottom-beam frame for the commercial vehicle liquefied gas bottles has great significance for popularization.

Description

technical field [0001] The invention relates to the field of commercial vehicles, in particular to a frame without a bottom beam for a liquefied gas cylinder for a commercial vehicle. Background technique [0002] Liquefied natural gas is an internationally recognized clean energy, with the characteristics of colorless, odorless, non-toxic, non-corrosive, small volume of the same amount of gas, and low cost of use. Therefore, more and more commercial vehicles use it as an alternative energy source in recent years. [0003] The frame of the liquefied gas cylinder in the prior art mostly adopts the structure of steel plate and / or steel pipe welded combination. The overall structure is divided into two layers, the upper layer is a saddle combination, and the lower layer is a bottom beam combination. Welding is easy to deform, and installation and disassembly are difficult, and the radial rotation and axial movement of the liquefied gas cylinder also occur from time to time dur...
