Abstract
The invention relates to the layout of a selective catalytic reduction (SCR) post treatment system of a national IV coach and in particular to a design method for a urea tank support assembly. The urea tank support assembly designed by using the design method for the urea tank support assembly comprises a support I (1), equilateral angle steel parts (2), a connecting plate I (3), a support II (4) and a connecting plate II (5), an included angle between two sides of each of the equilateral angle steel parts (2) is a right angle, the connecting plate I (3) is connected between level sides of the two parallel equilateral angle steel parts (2) in a welding mode, the connecting plate II (5) is connected between vertical sides of the two parallel equilateral angle steel parts (2) in a welding mode, the support I (1) with mounting holes is connected on the outer side of the vertical side of one of the equilateral angle steel parts (2) in a welding mode, and the support II (4) is connected on the vertical side of the other of the equilateral angle steel parts (2) in a welding mode. The design method for the urea tank support assembly enables the mounting structure of a urea tank to be more simplified and more light, and facilitates the assembling and the disassembling of the urea tank.
Description
Technical field
The present invention relates to the layout of state IV passenger vehicle SCR after-treatment system, particularly a kind of design method of urea tank bracket assembly.
Background technique
Along with the raising year by year that country requires passenger car discharging, increasing state IV passenger vehicle comes into the market.In limited space, will be light as much as possible for the support Design of SCR after-treatment system.State's IV is that China is for the pollutant emission standard that is equivalent to the Europe IV standard of implementation that light-duty vehicle is promulgated; together with the state III; be collectively referred to as light-duty vehicle pollutant emission limit and method of measurement (Chinese III, IV stage); by State Environmental Protection Administration's approval, April 27 announced on April 5th, 2005.SCR is exactly our said selective catalytic reduction technology, utilizes urea with the removal of nitrogen oxide in tail gas, to reach the exhaust emission standard of national regulation, that is to say that SCR is the part of automobile exhaust system.
Summary of the invention
The objective of the invention is: a kind of design method of urea tank bracket assembly is provided, and it more simplifies the mounting structure of urea tank, light.
The technical solution adopted for the present invention to solve the technical problems is: the design method that designs a kind of urea tank bracket assembly, it is characterized in that: the urea tank bracket assembly that designs by the method comprises support I, Equal Angle Steel, connecting plate I, support II, connecting plate II, the angle on two limits of described Equal Angle Steel is the right angle, the connecting plate I is welded between the horizontal edge of two Equal Angle Steels arranged side by side, and the connecting plate II is welded between the vertical edge of two Equal Angle Steels arranged side by side; Be welded with outside one of them Equal Angle Steel vertical edge with the support I that through hole is installed, be welded with the support II that through hole is installed outside another Equal Angle Steel vertical edge.
Described support I is " U " shape, and described support II is " L " shape.
Described Equal Angle Steel is the 40*40*4 angle steel, and unit is millimeter.
The invention has the beneficial effects as follows: adopt urea tank bracket assembly of the present invention, make weight support frame lighter, the mounting structure of urea tank is more simplified, and the dismounting of urea tank is more convenient.
Description of drawings
The present invention is further illustrated below in conjunction with embodiment, but not as the restriction to invention.
Fig. 1 is the urea tank bracket assembly structural representation of the embodiment of the present invention.
In figure: 1, support I; 2, Equal Angle Steel; 3, connecting plate I; 4, support II; 5, connecting plate II; 6, through hole is installed.
