Abstract
The utility model proposes a three-element catalytic converter with a thermal shroud, which comprises a three-element catalytic converter and a thermal shroud arranged outside the three-element catalytic converter; the thermal shroud is a semi-arc shroud formed through punching, and is arranged at the upper part of the three-element catalytic converter. As the semi-shielding type thermal shroud is designed, the three-element catalytic converter with the thermal shroud has the advantages of simple structure, lower cost and reliable function, thus optimizing the mounting mode of the thermal shroud of the three-element catalytic converter and being capable of reducing the cost of the entire vehicle.
Description
Technical field
The utility model belongs to automobile engine exhaust system, is used for the thermal environment around the ternary catalyzing unit is protected, and is specifically related to a kind of ternary catalyzing unit thermal shield.
Background technique
The technical thermal environment resist technology of car load plays an important role to the safety traffic of automobile, and ternary catalyzing unit is as main thermal source on the car load, and its surface temperature is up to 200 ℃-300 ℃.Heat protection for ternary catalyzing unit is even more important.The general hot protected-type of existing ternary catalyzing unit is for installing thermal shield additional, and the blocking-up thermal radiation reaches the effect of optimizing near the thermal environment of ternary catalyzing unit.At present the mode that installs additional of ternary catalyzing unit thermal shield mostly is full cover, and promptly two covers up and down all surround ternary catalyzing unit.But this kind mode materials are many, and the assembly technology complexity.Design that simple in structure a, assembly technology is simple, the thermal shield of reliable in function is particularly important.
Summary of the invention
The utility model is at the deficiencies in the prior art, proposes a kind of simple in structurely, and cost is lower, the ternary catalyzing unit with thermal shield of easy for installation, reliable in function.
Technical solutions of the utility model are as follows:
A kind of ternary catalyzing unit with thermal shield includes ternary catalyzing unit and is installed in the outer thermal shield of ternary catalyzing unit, and described thermal shield is stamping forming semicircular arc cover, is installed on the top of ternary catalyzing unit.
Thermal shield corresponds respectively to the mounting bracket and the ternary catalyzing unit body mounting points of ternary catalyzing unit by three points of left and right mounting points and back mounting points.
The stiffening rib of vertical perforation insulation surface is set on the thermal shield, and there is flange at the thermal shield rear portion.
The utility model has been owing to designed semi-cutoff thermal shield, and is simple in structure, cost is lower, reliable in function, has optimized the mounting type of ternary catalyzing unit thermal shield, can reduce integral vehicle cost.
Description of drawings
Fig. 1 is the structural representation of thermal shield;
Fig. 2 is a structural representation of the present utility model.
Wherein, the right mounting points (top welding projection welding nut) of 1-, 2-left side mounting points (top welding projection welding nut), mounting points behind the 3-, 4-stiffening rib, 5-rear portion flange, 6-ternary catalyzing unit, 7-thermal shield
Embodiment
Referring to Fig. 1 and Fig. 2, this ternary catalyzing unit 6 has adopted semi-cutoff thermal shield 7, thermal shield 7 is the impact briquetting integral structure, roughly become semicircular arc, be installed on the top of ternary catalyzing unit 6, mounting points has three, is left and right mounting points 2,1 and back mounting points 3, corresponds respectively to the mounting bracket and the ternary catalyzing unit body mounting points of ternary catalyzing unit.Be welded with project-welding nut on the left and right mounting points 2,1.Article two, stiffening rib 4 vertically connects insulation surface, has improved the intensity and the rigidity of thermal shield, and can reduce the deformation resilience after the part punching moulding.Thermal shield rear portion flange 5 is strengthened the thermal shield bulk strength.
