Description
Technical field
The utility model relates to the component of automobile, relates in particular a kind of three-element catalyzer of automobile engine assembly.
Background technique
Along with the develop rapidly of automotive industry, improve day by day to the requirement of motor car engine power character, Economy in market, and the Studying about Turbocharger of Engine device technology has obtained using widely, makes exhaust side of engine structural configuration more complicated.Generally, for guaranteeing vent systems performance and reliability requirement, ternary catalytic converter assembly mounting process has been carried out giving way and sacrificed, caused the problems such as exhaust-gas turbocharger motor ubiquity catalytic converter assembly installing space is narrow and small, general assembly efficiency is low, maintenance process is poor, maintenance cost is high.
Existing three-element catalyzer of automobile engine assembly as shown in Figure 8, comprises ternary catalyzing unit body 1 and reinforcing bracket 14, and wherein reinforcing bracket is overall structure, and reinforcing bracket one side is welded on catalyst converter, and opposite side is directly bolted on cylinder body.During assembling, because the bolton direction of reinforcing bracket is vertical with cylinder body side support attachment face, reinforcing bracket is when dismounting, and folding holding tool can interfere with catalyst converter body and some other component, causes ternary catalyzing unit general assembly and dismounting difficulty.On the other hand, necessary tool space when meeting assembling, spacing between two bolt mounting holes on existing reinforcing bracket is larger, must guarantee by increasing the structural strength of reinforcing bracket itself reliability of reinforcing bracket, cause the structural strength of reinforcing bracket itself higher, be easy to like this to occur constraint and the situation that causes other component of vent systems to lose efficacy.For example, because the rigidity of reinforcing bracket is higher than ternary catalyzing unit housing, ternary catalyzing unit housing is stainless steel thin-wall weldment, and the constraint of crossing due to reinforcing bracket causes ternary catalyzing unit housing to produce deformation in some cases.Again for example, in ternary catalytic converter assembly, waste gas streams is out-of-date, and ternary catalytic converter assembly expanded by heating, because the rigidity of reinforcing bracket is high, the constraint excessively of reinforcing bracket can not cushion this portion of energy by reinforcing bracket deformation, therefore may cause vent systems sealing surface distortion gas leakage problem.
Summary of the invention
The purpose of this utility model is to provide a kind of three-element catalyzer of automobile engine assembly, it can be avoided reinforcing bracket in disassembly process, to roll over holding tool and catalyst converter body and some other component and produce interference, can avoid again reinforcing bracket because intensity is high, to occur that constraint caused other component of vent systems to lose efficacy.
Three-element catalyzer of automobile engine assembly described in the utility model, comprise ternary catalyzing unit body and reinforcing bracket, ternary catalyzing unit body comprises ternary catalyzing unit central enclosure, reinforcing bracket is comprised of the first reinforcing bracket and the second reinforcing bracket, the first reinforcing bracket and the second reinforcing bracket be the stamping part that is L-type for consisting of two folding faces all, one folding face of the second reinforcing bracket is welded in ternary catalyzing unit central enclosure, one folding face of its another folding face and the first reinforcing bracket is bolted to connection, another folding face of the first reinforcing bracket offers for being fixed in the first bolt hole on cylinder body.
Further, one end of the folding face being fixedly connected with the first reinforcing bracket at the second reinforcing bracket is provided with the first project-welding nut, and its other end is provided with the first kink, offers the 4th bolt hole on the first kink; One end of the folding face being fixedly connected with the second reinforcing bracket at the first reinforcing bracket offers three bolt hole corresponding with the first project-welding nut position, its the other end is provided with the second kink, on the second kink, be provided with second project-welding nut corresponding with the 4th bolt hole position, the second kink is consistent with the bending degree of the first kink; Bolt spins by the 3rd bolt hole and the first project-welding nut, by the 4th bolt hole and the second project-welding nut, spins, and the second reinforcing bracket is fixedly connected with the first reinforcing bracket.By being provided with when kink give to be installed, reserve enough sleeve volume, be convenient to dismounting.
Further, the angle of two folding faces of the first reinforcing bracket is acute angle.After installation, the axis that ternary catalyzing unit central enclosure is corresponding and engine piston motion direction have certain angle, have reduced the vibration in piston movement direction, have improved product reliability.
During installation, first the first reinforcing bracket is fastened on cylinder body, the second reinforcing bracket is welded on ternary catalyzing unit body, then by bolt, the first reinforcing bracket is fixedly connected with the second reinforcing bracket.
Three-element catalyzer of automobile engine assembly described in the utility model, reinforcing bracket adopts detachable structure, because the first reinforcing bracket is first fixed and is connected with cylinder body, and the first reinforcing bracket is when be connected with the second reinforcing bracket bolt, bolton direction is not vertical with cylinder body side the first reinforcing bracket attachment face, changed the fastening direction of bolt when ternary catalytic converter assembly is installed, thereby obtained the space of construction bolt, having avoided folding holding tool and ternary catalyzing unit body and its Surrounding Parts to produce interferes, efficiently solve ternary catalyzing unit general assembly and dismantle difficult problem.In addition, because the size of reinforcing bracket in the utility model is little with respect to the size of existing reinforcing bracket, the distance of two bolts hole of installing with side of cylinder block on support is less, under the prerequisite of reliability that meets reinforcing bracket, the stiffness of the comparable existing reinforcing bracket of stiffness of this reinforcing bracket is lower, has avoided the constraint of crossing of reinforcing bracket to cause ternary catalyzing unit housing to produce deformation.Because the first reinforcing bracket and the second reinforcing bracket are the stamping part that is L-type, on overbending direction, mode is lower, during ternary catalytic converter assembly expanded by heating, the bending place of reinforcing bracket easily produces deformation and absorbs part energy, has avoided reinforcing bracket to cross constraint and the vent systems sealing surface distortion gas leakage problem that causes.
