Abstract
The present invention provides a kind of commercial car post processing and uses pressure difference sensing device assembly, stainless steel tube assembly（3）, silicone tube（4）, silencer hoop（6）；Catalytic trap silencer（1）By silencer hoop（6）It is fixed on vehicle frame lower aerofoil；Differential pressure pickup（7）Pass through silicone tube（4）And stainless steel tube assembly（3）With bearing before differential pressure pickup（5）And differential pressure pickup rear support（2）Connection；Silencer hoop（6）Be open bias 60mm, silencer hoop（6）Upper end is disposed with 4 mounting holes（8）, differential pressure pickup（7）It is bolted on silencer hoop（6）Upper end.The present invention changes the connecting mode and installation site of differential pressure pickup and catalytic trap silencer, simple and compact for structure, and connection is reliable reasonable, not only effectively reduces cost, and better met the performance requirement of commercial car post processing differential pressure pickup.
Description
Technical field
Correlation technique is post-processed the present invention relates to automobile, pressure difference sensing device assembly is used in specially a kind of commercial car post processing.
Background technology
The engine EGR after-treatment system of Yuchai state four is designed using POC+DOC, and the differential pressure pickup of the system has two sockets, by with silicone tube, take gas steel pipe to be connected to measure the pressure drop of EGR air inlets and gas outlet.EGR calculates the EGR gas flows for entering inlet valve using the pressure drop.This result of calculation is used for the location of instruction for determining EGR valve, so as to control the flow into the EGR gases of engine.
The assembling of usual differential pressure pickup, it need to be punched in vehicle frame breadth, then frame inside is assemblied in by fixed support, specific installation site need to be depending on the position according to catalytic trap silencer, therefore differential pressure pickup confined state is difficult unification, and destroys the intensity of vehicle frame, cause that differential pressure pickup enters outlet joint steel pipe and pipeline state is unreasonable, joint is complicated, and efficiency of assembling is not also high, there is the irrational problem of design.In addition, the fixed of catalytic trap silencer uses steel band type hoop, differential pressure pickup damage is also easily caused, while product appearance and homogeneity of product also are difficult to ensure.
The content of the invention
The present invention in order in order to solve the above technical problems, provide a kind of commercial car post processing pressure difference sensing device assembly,.
The technical scheme is that：Pressure difference sensing device assembly, including vehicle frame are used in a kind of commercial car post processing, it is characterised in that：Pass through silencer hoop on vehicle frame lower aerofoil（6）It is fixedly connected with catalytic trap silencer（1）；Silencer hoop（6）Upper end is disposed with 4 mounting holes, for fixing differential pressure pickup（7）；Differential pressure pickup（7）Pass through stainless steel tube assembly（3）Respectively with bearing before differential pressure pickup（5）With differential pressure pickup rear support（2）Connection；Bearing before differential pressure pickup（5）With differential pressure pickup rear support（2）It is separately fixed at catalytic trap silencer（1）On.
Further improve is：Bearing before differential pressure pickup（5）And differential pressure pickup rear support（2）With stainless steel tube assembly（3）Between be additionally provided with silicone tube（4）.
Further improve is：Described stainless steel tube assembly（3）For moulding pipe, thickness of steel pipe 1mm.Further improve is：Silicone tube（4）For shaping silicone tube.
Further improve is：Silencer hoop（6）Be open bias 60mm, silencer hoop（6）Upper end is disposed with 4 mounting holes, for fixing differential pressure pickup（7）.
Beneficial effect：
The mounting arrangement of the present invention causes POC+DOC to be designed beautifully, wire harness moves towards smooth reasonable, vehicle frame hole position specification, the present invention is on the basis of differential pressure pickup matching requirements and technical requirements are ensured, change conventional differential pressure pickup and determined according to the position of catalytic trap silencer the situation of confined state, also situation about being punched in the past on vehicle frame is changed, re-optimization devises the fixation hoop of catalytic trap silencer, differential pressure pickup is enabled to realize batch production with stainless steel tube assembly and silicone tube, not only compact conformation is attractive in appearance, and reduces assembly difficulty.
Silencer hoop（6）Be open bias 60mm, silencer hoop（6）Upper end is disposed with 4 mounting holes, for fixing differential pressure pickup（7）, the general assembly of pressure difference sensing device assembly can be achieved, efficiency of assembling is effectively improved, it is ensured that product quality and technical requirements, outward appearance and homogeneity of product have also obtained significantly improving.
Stainless steel tube assembly（3）For moulding pipe, silicone tube（4）For shaping silicone tube, it is possible to achieve batch production, it is to avoid the situation that conventional scene is bent, production cost is reduced, improve assembling speed；Thickness of steel pipe 1mm, it is ensured that intensity also saves material.
