Abstract
The utility model provides a reinforcing bracket assembly for an automobile engine catalyst, which comprises a welding bracket and a connecting bracket, wherein the welding bracket adopts a punched long plate piece, and the welding bracket is welded on the midway of the catalyst through the arc flange at the upper middle part in the length direction of the welding bracket; and the connecting bracket adopts a punched long plate piece with a L-shaped cross section, the two ends of the bottom surface of the connecting bracket are connected with the two ends of the welding bracket through projection weld nuts and bolts, and bolt holes consisting of an interference round hole and a kidney-shaped hole are formed at the two ends of the vertical face of the connecting bracket and connected with the engine cylinder. The reinforcing bracket assembly for automobile engine catalyst can adjust the assembly degrees of freedom of the X,Y and Z directions at the same time, better remove assembly and heat expansion stresses, remove the resonance vibration of the catalyst and an exhaust system and prevent the breakage, has compact and simple structure, and is easy to assemble.
Description
Technical field
The utility model relates to the catalyst converter of engine exhaust system, is specifically related to the reinforcing bracket structure of catalyst converter.
Background technique
Along with the raising of user to car mass and travelling comfort requirement, this just requires the vibration of motor car engine more and more littler, satisfies 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.Usually, catalyst converter need be done support by reinforcing bracket, is connected and fixed with engine cylinder-body.Therefore the design of the reinforcing bracket of catalyst converter directly has influence on the reliability of catalyst converter.As depicted in figs. 1 and 2, catalyst converter welding support 1 is welded on the catalyst converter 4, and its two ends are connected and fixed with engine cylinder-body 5 by the connection double-screw bolt 2 of band interference mounting hole 3.When reinforcing bracket assembles at assembly, can only regulate the assembly error and the erection stress of directions X usually, for Y, Z direction, then not have the erection stress of bringing when way is eliminated assembling by the interference design of mounting hole.So, always there is certain erection stress in part after the assembly assembling, product reliability is brought harmful effect.
Summary of the invention
The utility model is at existing catalyst converter vibration and integrity problem, and purpose provides a kind of catalyst converter reinforcing bracket assembly, solves the ordinary construction reinforcing bracket and easily produce erection stress when assembly is installed, thereby influence the reliability problems of whole catalyst converter; Solve the resonance of catalyst converter and vent systems, and catalyst converter is excessively limited thermal expansion and cause stress excessive, produced the problem of fracture.
The technical solution of the utility model and effect are as follows:
A kind of reinforcing bracket assembly of motor car engine catalyst converter, it includes welding support, and described welding support is a punching press long slab spare, and described welding support is welded on half waist of catalyst converter by middle part circular arc flange on one side on the length direction; It comprises that also one connects support, described connection support is that a cross section is L shaped punching press long slab spare, the two ends, bottom surface that connect support are connected with the welding support two ends with bolt by project-welding nut, the facade two ends that connect support are provided with the bolt hole that is connected with engine cylinder-body, are respectively interference circular hole and waist shaped hole.
Described connection support dashes in the longitudinal direction flange, and also dashing in its L shaped bending place has stiffening rib.
The utility model is considered the thermal expansion factor of catalyst converter and reinforcing bracket, the reinforcing bracket assembly is divided into the form that two supports connect to form, to connect the support global design is long plate shape, connecting support adopts the interference circular hole to combine with waist shaped hole with the bolt hole of engine cylinder-body connecting end, assembly error on the can regulate directions X guarantees that assembling is smooth and easy; Simultaneously, connecting support is connected with bolt is urgent in the Y direction with engine cylinder-body, be connected with bolt is urgent in the Z direction with welding support, add the interference hole matching design of directions X, when catalytic converter assembly assembles,, can eliminate the erection stress of X, Y, Z direction simultaneously by regulating the bolt torsion of different direction, improve product reliability, guarantee that simultaneously the assembly assembling is more smooth and easy.
Further, connecting support has the stiffening rib of arranging along the Y direction at the L bending part, makes it have certain flexibility in the Z direction, avoids the component thermal stress excessive and rupture.Connect support and promptly also have flange, can improve catalyst converter and whole vent systems rigidity, avoid the motor resonant belt along directions X at length direction.
As fully visible, this support of bracket assembly of the utility model design can be regulated the assembling degrees of freedom of X, Y, three directions of Z simultaneously, has and eliminates assembling and thermal expansion stress better, clear up the resonance of catalyst converter and vent systems, prevent to produce the advantage of fracture, compact structure, simple is easy to assembling.

Embodiment
Referring to Fig. 3 and Fig. 4, this catalyst converter reinforcing bracket assembly by welding support 1 be connected support 6 and form.Wherein welding support 1 all is the long slab spare that adopts the thick steel plate of 3mm to be stamped to form with being connected support 6.Welding support 1 middle part in the longitudinal direction has the circular arc flange on one side, is used for being welded to connect with catalyst converter.The two ends of welding support 1 are welded with project-welding nut.The cross section that connects support 6 is L shaped, its two ends, bottom surface are connected by the project-welding nut of bolt with welding support 1 two ends, the facade two ends that connect support 6 are provided with the bolt hole that is connected with engine cylinder-body, are respectively interference circular hole 62 and waist shaped hole 61, to regulate the build-up tolerance on the directions X.Connecting support 6 when impact briquetting, in order to increase rigidity, is that the directions X upper punch has flange 63 in the longitudinal direction, and also dashing in its L shaped bending place has stiffening rib 64.
Referring to Fig. 5, during installation, welding support 1 is welded on half waist of catalyst converter 4, connect support 6 and be connected by bolt is urgent with welding support 1, the urgent direction of bolt is the Z direction; Connecting support 6 and engine cylinder-body is interference circular hole 62 by tapped hole and the usefulness bolt is urgent is connected for waist shaped hole 61, and the urgent connecting direction of bolt is the Y direction.
