Abstract
The utility model relates to an installing and strengthening structure of a motor vehicle catalyst converter assembly, comprising a catalyst converter and a strengthening bracket which installs the catalyst converter to an engine cylinder body; the main body of the strengthening bracket is in a press-forming flat plate shape, and one side of the strengthening bracket is provided with an arc gap, and the catalyst converter shell body is welded at the arc gap, and the left end and the right end of the strengthening bracket are respectively provided with a pair of installing ears with a bolt through hole which are perpendicular to the bracket plane, and the strengthening bracket is connected with the cylinder body through the bolt. The strengthening bracket is designed as the flat plate shape in the structure, and strengthening ribs are arranged along Y direction, and the strengthening bracket and the catalyst converter are not overall welded together, only single side welding is conducted, therefore, the rigidity of the bracket is moderate, the radian of the arc gap is smaller than 180degrees, that is, the part which is welded with the catalyst converter shell body does not reach 1 / 2 of the whole shell body, therefore, the a certain flexibility is provided at Z direction, and a certain thermal expansion is provided at Z direction of the catalyst converter, and the rupture caused by excessive thermal stress of the catalyst converter is avoided.
Description
Technical field
The utility model relates to the motor car engine technical field, is specifically related to the catalytic converter assembly mounting structure of engine exhaust system.
Background technique
Along with the subscriber computer motor-car to quality and travelling comfort require more and more higher, require the vibration of motor car engine more and more littler, satisfy the use of complex working condition and rugged environment.Because catalyst converter belongs to the very big component of heat load in the motor, therefore the design to catalyst converter has proposed requirements at the higher level.Catalyst converter is installed on the engine cylinder-body by reinforcing bracket, and the design of catalyst converter reinforced structure for installation directly has influence on its reliability.Current catalyst converter reinforced structure for installation as shown in Figure 1, arc reinforcing bracket 1 is welded on the catalyst converter 3, bolt passes the double-screw bolt 2 that is welded on arc reinforcing bracket 1 two ends support is connected with cylinder body.Because arc reinforcing bracket 1 integral body all is welded on the catalyst converter 3, and as Fig. 2, this curved support 1 has stiffening rib 4 along arcuate directions, and stiffness of support will be very high like this, will limit the catalyst converter thermal expansion, causes its stress excessive and rupture.
Summary of the invention
The purpose of this utility model is excessive at existing catalyst converter stiffness of support, limited the problem of the thermal expansion of catalyst converter, a kind of compact structure, the simple reinforced structure for installation of catalytic converter assembly of production technology are proposed, solution is excessive because of the catalyst converter stiffness of support, the thermal expansion of restriction catalyst converter, and cause catalyst converter stress excessive, produce the situation of fracture.
The technical solution of the utility model:
A kind of automotive catalytic device assembly reinforced structure for installation, it comprises catalyst converter and catalyst converter is installed to reinforcing bracket on the engine cylinder-body; The main body of described reinforcing bracket is stamping forming straight tabular, there is arc gap on one side of reinforcing bracket, the catalyst converter housing is welded on described arc gap place, the two ends, the left and right sides of reinforcing bracket are provided with the mounting ear of a pair of strap bolt through hole vertical with the support plane respectively, are connected with cylinder body by bolt.
The arc gap radian of described reinforcing bracket is less than 180 °, interference is installed with the reinforcement double-screw bolt respectively between two mounting ears of every pair of mounting ear at two ends, the described support left and right sides, strengthening center stud has bolt hole, and described bolt passes mounting ear and is connected with cylinder body with the reinforcement double-screw bolt.
This catalytic converter assembly mounting structure is owing to be designed to reinforcing bracket straight tabular, the stiffening rib that the reinforcing bracket plate part is not arranged along the Y direction, and reinforcing bracket and catalyst converter do not have integral solder together, only carry out monolateral welding, therefore stiffness of support is moderate, further the arc gap radian of reinforcing bracket is less than 180 °, promptly with the part of catalyst converter housing welding less than 1/2 of its whole housing full circle, therefore it has certain flexibility in the Z direction, allow that catalyst converter Z direction has certain thermal expansion, avoid the catalyst converter thermal stress excessive and rupture.

Fig. 1 is the schematic representation of existing reinforced structure for installation of catalytic converter assembly;
Fig. 2 is the structural representation of existing reinforcing bracket;
Fig. 3 structural representation of the present utility model;
Fig. 4 catalytic converter assembly is installed to the schematic representation on the cylinder body.
Embodiment
Referring to Fig. 3, Fig. 4, reinforced structure for installation of catalytic converter assembly comprises reinforcing bracket 5, strengthens double-screw bolt 6, catalyst converter 3.The main body of reinforcing bracket 1 is straight tabular, Yi Bian radian is arranged less than 180 ° arc gap, the welding of the housing of this arc gap and catalyst converter 3.Two ends, described reinforcing bracket 1 left and right sides are provided with a pair of mounting ear vertical with the support plane 7 respectively, this mounting ear 7 and reinforcing bracket 5 integrated punching moulding, design has bolt hole at mounting ear 7 middle parts, strengthen double-screw bolt 5 centers and be provided with bolt hole, strengthening double-screw bolt 6 blocks respectively between every pair of mounting ear 7, and interference fit, reinforcing bracket 5 usefulness bolts pass mounting ear 7 and strengthen double-screw bolt 6 and realize and being connected of cylinder body 8.
