Abstract
The utility model relates to a novel box SCR case support has solved heavy truck and has matchd square SCR case and have that the space is not enough, difficult scheduling problem is arranged in the installation. The utility model discloses a square steel and base, the square steel divide into straight -line portion and curvature, the base include the sleeve, tip, the other end that telescopic one end suit was fixed at the square steel curvature are fixed with the connection fixed plate, connect and have seted up the connecting hole on the fixed plate. Through the utility model discloses the box SCR case of support mounting, it is compacter to make whole car arrange, verifies through market, and whole section blast pipe generally can not exceed 20 DEG C no longer than 1.5m, the exhaust difference in temperature, can reduce the not enough risk of urea crystallization and nitrogen oxide conversion, and is more favourable to the after treatment system operation, guarantees promptly that whole car has stronger dynamic property.
Description
Technical field
The utility model relates to technical field of vehicle manufacture, specifically a kind of novel box type SCR box bracket.
Background technique
The vehicle of SCR technology path motor is mated in state four and state five, after-treatment system is furnished with requirements at the higher level to outlet pipe, empirical tests is analyzed, car load outlet pipe (from turbine outlet to SCR tank inlet) is long makes delivery temperature decline excessive, urea decomposition can be caused insufficient, then generate urea crystals body, cause outlet pipe to block, power performance declines; Delivery temperature declines excessive in addition, and SCR case transformation efficiency also can be caused not enough, and cause OBD to occur the phenomenon that exceeds standard, car alarming or limit are turned round.When blast duct for vehicle is long, advise that whole section of outlet pipe increases thermal insulation layer.
Current domestic state four heavy truck SCR case profile mainly contains box (square) and tub, and common tub SCR case arrangement is simple, and general gas exhaust piping is longer; Square SCR case arrangement is compact, and gas exhaust piping is generally shorter, thus for considering reprocessing transformation efficiency, and not adding outlet pipe thermal insulation layer with cost-saving, square SCR case is mated in suggestion as far as possible.And car load mates square SCR case, some vehicle there will be insufficient space, the problems such as mounting bracket difficult arrangement.
Summary of the invention
The purpose of this utility model mates the problems such as square SCR case Existential Space deficiency, difficulty in installation and layout to solve heavy truck, and provide a kind of novel box type SCR box bracket.
The utility model is achieved by the following technical solution:
A kind of novel box type SCR box bracket, comprise square steel and base, described square steel is divided into straight section and curved section, and described base comprises sleeve, one end suit of sleeve is fixed on the end of square steel curved section, the other end is fixed with and is connected and fixed plate, is connected and fixed on plate and offers attachment hole.
During use, as shown in Figure 4, the utility model support is fixed respectively in the both sides, top of box SCR case, wherein, straight section and the box SCR case of square steel are fixed, the plate co-used engine rear suspension bracket fastening piece that is connected and fixed of base is fixed on vehicle frame, and the curved section of square steel can avoid the parts such as spring carrying block.
Further, the attachment hole be connected and fixed on plate of described base is bar hole.Such design is to consider manufacturing process error, thus ensures its assembly performance.
Be fixed with stiffening rib between the sleeve of described base and fixed connecting plate, thus further increase intensity of the present utility model.
By the box SCR case of the utility model support installing, arrangement can be made compacter, verify through market, whole section of outlet pipe is no more than 1.5m, the exhaust temperature difference generally can not more than 20 DEG C, the risk of urea crystals and conversion of nitrogen oxides deficiency can be reduced, run more favourable to after-treatment system, namely ensure that car load has stronger power character.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the plan view of Fig. 1.
Fig. 4 of the present utility modelly installs and uses schematic diagram.
In figure: 1-square steel, 2-base, 2-1-sleeve, 2-2-are connected and fixed plate, 2-3-attachment hole, 2-4-stiffening rib, the box SCR case of 3-.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1 to Figure 3, a kind of novel box type SCR box bracket, comprise square steel 1 and base 2, described square steel 1 is divided into straight section and curved section, described base 2 comprises sleeve 2-1, one end suit of sleeve 2-1 is fixed on the end of square steel 1 curved section, the other end is fixed with and is connected and fixed plate 2-2, is connected and fixed on plate 2-2 and offers attachment hole 2-3.
During concrete enforcement, the attachment hole 2-3 be connected and fixed on plate 2-2 of described base 2 is bar hole; Stiffening rib 2-4 is fixed with between the sleeve 2-1 of described base 2 and fixed connecting plate 2-2; The material selection Q235 steel of described square steel 1 and base 2.The box SCR box bracket of the utility model is drawn by cae analysis: vertical impact operating mode stress maximum value is 71.9MPa, and it is 12.5Mpa that operating mode stress maximum value is impacted in braking.
