A urea tank fix structure for rear passenger car

Abstract

The invention discloses a urea tank fix structure for rear passenger car comprising a supporting structure, a fixing urea tank bracket, a fixing strap and fixing bolt nut, wherein the supporting structure and the fixing urea tank bracket are L-shaped structures, and the L-shaped supporting structure forms a closed fixing structure with the bus body. The invention has the advantages that: The fixing structure adopts L-shaped fixed urea tank bracket and L-shaped fixed urea tank bracket to ensure that the urea tank is positioned and fixed in multiple directions, meanwhile, the fully threaded bolts at the two ends of the fixing strap and the fixing holes reserved at the two ends of the fixing urea tank bracket form a closed fixing structure, thereby improving the fixing stability of the ureatank; Each part of the fixing structure is independent of each other, and each part is connected and fixed by bolts and nuts, so as to ensure the installation and positioning effect of the urea tank,and meanwhile, the installation and fixing efficiency is improved by bolt fixation; The fixed structure is firm and durable, has good social benefits, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to a fixing structure, in particular to a rear passenger car urea tank fixing structure, and belongs to the technical field of urea tank fixing structure application. Background technique [0002] At present, with the rapid development of the automobile industry, due to the increasingly serious air pollution, the greenhouse effect is becoming more and more obvious, and the requirements for automobile emissions that affect this result are also getting higher and higher; the post-processing of passenger cars is under these requirements With the added device for improving emissions, the tail gas passes through the post-treatment liquid in the urea tank to further reduce the emission of pollutants, making an important contribution to improving the environment. The fixed structure for the installation of the urea tank used in this post-processing is also particularly important. The fixed structure ensures the normal operation of the ur...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing rear fixed structure of passenger car urea tank cannot fix the urea tank in multiple directions, resulting in the fixing structure not being firm enough for the urea tank, and the position of the fixing structure for fixing the urea tank is not accurate enough, Reliable, the fixed structure is not convenient and fast enough for installation, use or disassembly, and the flexibility and adjustability of the fixed structure are low, so a rear-mounted bus urea tank fixed structure is proposed
