Abstract
The utility model belongs to commercial vehicle after-treatment system technical field, and in particular to a kind of underface opening type end side heat shield structure suitable for commercial platform-type SCR.The underface opening type end side heat shield structure of the utility model includes reinforcing rib, bolt hole, heat shield center reinforcement structure, supplement five parts of reinforcing rib structure and slot, supplement reinforcing rib is triangular structure, and being designed as of slot can avoid escape pipe and the U-shaped slotted section that designs.The heat shield structure of the utility model, the demand for being located at the after-treatment system heat shield of box end face about entry/exit tracheae in the market is met, solves the problems, such as that vehicle noise problem caused by high vibration abnormal sound existing for such heat shield and after-treatment system service life reduce.
Description
Technical field
The utility model belongs to commercial vehicle after-treatment system technical field, and in particular to one kind is suitable for commercial platform-type
The underface opening type end side heat shield structure of SCR.
Background technique
Commercial vehicle SCR(Selective Catalytic Reduction, abbreviation SCR) box after-treatment system it is general
There are many types, but main box is essentially identical in the box after-treatment system of corresponding mainstream car design, difference is to match
Different vehicle deployment scenarios, the gas entry outlet arranged on cabinet and exhaust outlets position difference are with end face in the outer part
Example, is broadly divided into four kinds of forms, either with or without arrangement escape pipe, has escape pipe position to be located at end face center, there is escape pipe
Position position located directly below, also there is escape pipe to be located at lower right position.Because the difference of escape pipe position leads to the end
Face heat shield form is also different therewith.In the structure of box after-treatment system, on the one hand heat shield carries high in isolation case
Injury of the wet body to adjacent components and road surface pedestrian, on the other hand, heat shield is fixed on end cap by mounting bracket, is held
By the oscillating load passed over by engine.The performance of heat shield currently on the market can only meet basic insulation requirement,
The unbearable oscillating load passed over by engine vibrates abnormal sound without causing.On the one hand the vibration abnormal sound of heat shield can be led
The fracture failure of heat-insulated cover body is caused, on the other hand, because it is connected with end cap, easily drive end cap vibration, to the tired of end cap
Labor is durable also to have a great impact.Therefore it designs and is able to satisfy the heat shield of performance requirements and is particularly important.
Summary of the invention
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art, provide a kind of be applicable in
In the underface of commercial platform-type SCR opening type end side heat shield structure.The underface opening type end side of the utility model is heat-insulated
Cover structure is suitable for the box after-treatment system that commercial vehicle escape pipe is located at center immediately below end face, increases the rigid of heat shield
Degree reduces the risk of heat shield vibration abnormal sound and cracking.
In order to solve the above technical problems, the technical solution adopted in the utility model is: one kind being suitable for commercial platform-type SCR
Underface be open type end side heat shield structure, which is characterized in that underface is open type end side heat shield structure with following
Feature:
A kind of underface opening type end side heat shield structure suitable for commercial platform-type SCR, including reinforcing rib, bolt
Hole, heat shield center reinforcement structure, supplement five parts of reinforcing rib structure and slot, the supplement reinforcing rib are triangle knot
Structure.
The reinforcing rib is half ring-like reinforcing rib structure, only covers the top and the left and right sides of heat shield, does not cover bottom edge.
The bolt hole is connected with after-treatment system end cover bracket, is distributed in five-point type.
In a ring, the center portion thereof sets up the supplement reinforcing rib structure for being equipped with triangle separately to heat shield center reinforcement structure.
The slot is U-shaped hole, can avoid the U-shaped notching construction of escape pipe, the diameter of the semicircular structure in the U-shaped hole
For 130mm-140mm.
Compared with the prior art, the utility model has the following advantages:
The heat shield structure of the utility model is located at end face bottom right mainly for commercial vehicle air inlet in the market or escape pipe
The box after-treatment system of Fang Zhongxin, the bolt pore size distribution of five-point type, is verified through finite element analysis, can effectively improve heat shield side
Face part mode of oscillation effectively raises the rigidity of such end face heat shield by the targetedly design to five parts,
The risk for reducing end face heat shield vibration abnormal sound and cracking, has the reliability of box after-treatment system end cap heat shield larger
Meaning.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of opening type end side heat shield immediately below the utility model.
Fig. 2 is the main view of opening type end side heat shield immediately below the utility model.
Description of symbols: 1- reinforcing rib；2- bolt hole；31- heat shield center reinforcement structure；32- supplements reinforcing rib knot
Structure；4- slot.
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Specific embodiment
A kind of underface opening type end side heat shield structure suitable for commercial platform-type SCR, including reinforcing rib 1, bolt
Hole 2, heat shield center reinforcement structure 31, supplement 4 five parts of reinforcing rib structure 32 and slot, the supplement reinforcing rib 32 are three
Angular structure.
The reinforcing rib 1 is half ring-like reinforcing rib structure, only covers the top and the left and right sides of heat shield, does not cover bottom
Side.
The bolt hole 2 is connected with after-treatment system end cover bracket, is distributed in five-point type, specially 1 point of top, left and right
Each 1 point, 5 bolt hole structures are arranged in each 1 point of two sides of nozzle opening altogether.
In a ring, the center portion thereof sets up the supplement reinforcing rib for being equipped with isosceles triangle separately to heat shield center reinforcement structure 31
Structure 32, apex angle are 54 degree, remaining two corners is all 63 degree.
The slot 4 is U-shaped hole, can avoid the U-shaped notching construction of escape pipe, the semi-circular structure in the U-shaped hole is straight
Diameter is 130mm.
Above-described implementation is only that preferred embodiments of the present invention are described, not practical new to this
The range of type is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this reality
The various changes and improvements made with novel technical solution should all fall into the protection model that the utility model claims book determines
In enclosing.
