Abstract
The utility model discloses a bracket for the heat insulation cover of the exhaust manifold and catalytic converter of the automotive engine, which comprises a body of the bracket having a cross-section in the V shape. The bracket is characterized in that a first welding screw nut and a second welding screw nut are symmetrically arranged on the inner side of the body of the bracket; an installation hole of a first heat insulation cover and an installation hole of a second heat insulation cover are symmetrically arranged on the installation plane of the first heat insulation cover and the installation plane of the second heat insulation cover respectively on the outer side of the bracket body; the central line of the installation hole of the first heat insulation cover is coaxial with the central line of the first welding screw nut, while the central line of the installation pore of the second heat insulation cover is coaxial with the central line of the second welding screw nut. The utility model has advantages that because the body of the bracket is in the V-shaped structure, two installation planes of the heat insulation cover are formed, so that the upper and lower heat insulation covers of the catalytic converter are assembled onto the same bracket, problems of strength and interval of the cantilever type single sheet shaped bracket, as well as problems of cost and process of the single pore type U shaped bracket are successfully solved, and influence and welding to the housing of the catalytic converter can be decreased.
Description
Technical field
The utility model relates to automobile engine exhaust system, is specifically related to the thermal shield support of a kind of automobile engine to exhaust manifold and catalyst converter
Background technique
In order to reach higher emission standard and to save cost, at present increasing motor car engine begins to adopt stainless exhaust manifold band catalytic converter assembly, and this is a kind of vent systems of tight coupling type.Because cabin space is limited, the catalyst converter surface temperature is higher in addition, so need increase thermal shield outside catalyst converter, is damaged by its high temperature to prevent other component.In order to guarantee between the effective distance between thermal shield and the catalyst converter, guarantee that simultaneously thermal shield can effectively fix, generally need be at the front end and back end of catalyst converter body design thermal shield support.Commonly used is beam type L bracket or monotrysian type U type support at present, the beam type L bracket is struck out L shaped usually by steel plate, one end is unsettled to be used at both sides assembling thermal shield up and down, the other end is welded on the catalyst converter body, owing to the spatial arrangement reason, it is too big that the beam type L bracket often can not be done, though can fix thermal shield up and down simultaneously, but mode does not reach requirement, causes the vibration of thermal shield easily; Monotrysian type U-shaped support strikes out U-shaped by steel plate, a mounting plane and a mounting hole that is used for the thermal shield location is arranged, a monotrysian type U-shaped support can only be fixed a point of a thermal shield, but four points of both sides were fixed about the catalyst converter thermal shield needed usually, this just causes a side of catalyst converter housing need weld four identical monotrysian type U-shaped supports, causes waste of material, welding and complex process.
Summary of the invention
The purpose of this utility model is that it is simple in structure, welding is easy to assembly by the thermal shield support of a kind of automobile engine to exhaust manifold and catalyst converter, connection is reliable, can improve the reliability of thermal shield assembling, can realize the reduction of cost, the simplification of technology again.
The thermal shield support of a kind of automobile engine to exhaust manifold described in the utility model and catalyst converter, comprise that section is the rack body of " V " type, it is characterized in that: be provided with first welded nut and second welded nut symmetrically in the inboard of rack body, the first thermal shield mounting plane in the rack body outside, be respectively equipped with the first symmetrical thermal shield mounting hole on the second thermal shield mounting plane, the second thermal shield mounting hole, the center line of the first thermal shield mounting hole is coaxial with the center line of first welded nut, and the center line of the second thermal shield mounting hole is coaxial with the center line of second welded nut; The aperture of the first thermal shield mounting hole and the second thermal shield mounting hole is slightly larger than the nominal diameter of first welded nut and second welded nut, to be advisable about big 2mm.
The thermal shield support of described a kind of automobile engine to exhaust manifold and catalyst converter, the first thermal shield mounting plane in its described rack body outside and the angle α between the second thermal shield mounting plane are the obtuse angle, are advisable with about 150 °.
The thermal shield support of described a kind of automobile engine to exhaust manifold and catalyst converter is provided with symmetrically with it on the both sides of rack body and is first extending pin of one and second extending pin, and first extending pin is fixedlyed connected with the catalyst converter housing respectively with second extending pin.
The thermal shield support of described a kind of automobile engine to exhaust manifold and catalyst converter, its described first welded nut and second welded nut are connected to a shaping by welding and rack body, and the catalyst converter thermal shield is installed on first welded nut and second welded nut by bolt.
The utility model is compared with prior art and is had the following advantages: because rack body is " V " type structure, two thermal shield mounting planes have been formed, thereby the thermal shield up and down that makes catalyst converter is assemblied on the support, successfully solved cost, the technological problems of intensity, clearance issues and the monotrysian type U-shaped support of beam type monolithic shape support, can also reduce of the influence of welding reason simultaneously the catalyst converter housing.
