Abstract
The utility model relates to a manifold catalytic converter, which comprises a catalyst casing assembly. Two ends of the catalyst casing assembly are respectively provided with a gas inlet end cone assembly and a gas outlet end cone assembly, and the gas outlet end cone assembly is provided with a gas outlet flange. The manifold catalytic converter is characterized in that the gas inlet end cone assembly is connected with a gas inlet flange through a clamshell manifold, and a support is disposed on the gas outlet end cone assembly. The manifold catalytic converter has the advantage of being capable of meeting space arrangement requirements of cast iron manifolds, having better sealing property, reducing total installation difficulty, and simultaneously reducing support breakage possibility.
Description
Technical field
The utility model relates to a kind of manifold catalyst converter.
Background technique
Along with the more and more strictness of national Abgasgesetz, to the light-off time of catalyst converter, the requirement that structure is durable is more and more higher.In order to improve the ignition of catalyst converter, the Raw exhaust temperature of motor increases, and traditional cast iron type gas exhaust manifold is because heat resisting temperature hangs down the usage requirement in the time of can not satisfying high temperature.Simultaneously, in order to reduce complete vehicle quality, gas exhaust manifold gets light-weight design and also is introduced into.But owing to adopted the inlet flange of thin plate, there is the risk of leaking in the inlet flange aspect because constantly thermal cycle produces distortion.In addition, the manifold catalyst converter directly is connected with motor, does not have other part to carry out damping, will directly bear high temperature, the load of high vibration, and supporting structure often produces fracture.
Summary of the invention
The purpose of this utility model provides a kind of catalyst converter, with installation, layout, heat management and the emission request that satisfies catalyst converter.
The technical solution of the utility model has provided a kind of manifold catalyst converter in order to achieve the above object, comprise the catalyst housing assembly, be respectively equipped with inlet end awl assembly and outlet side awl assembly at catalyst housing assembly two ends, on the awl assembly of outlet side, be provided with the flange of giving vent to anger, it is characterized in that, inlet end awl assembly is connected with inlet flange by the clampshell manifold, props up to be set up on the awl assembly of outlet side.
Further, described support is connected with described outlet side awl assembly by assembly structure.Described clampshell manifold is divided into go up a slope section and lower slope section along same curved surface.Edge and air flue place at described inlet flange are provided with flanging respectively.Described inlet flange is provided with the sealing surface of projection.
The utility model has the advantages that: can satisfy the spatial arrangement requirement of former cast iron manifold; Has better sealability; Reduce total installation difficulty, also avoided the crack conditions of support simultaneously.

Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, a kind of manifold catalyst converter that provides for the utility model, comprise catalyst housing assembly 4, be respectively equipped with inlet end awl assembly 3 and outlet side awl assembly 5 at catalyst housing assembly 4 two ends, on the awl assembly 5 of outlet side, be provided with the flange 6 of giving vent to anger, inlet end awl assembly 3 is connected with inlet flange 1 by clampshell manifold 2, and support 7 is located on the awl assembly 5 of outlet side.
As shown in Figure 2, support 7 is connected with outlet side awl assembly 5 by assembly structure 8.Support 7 is if directly be welded on catalyst housing assembly 4; because temperature is very high during welding; usually can the liner in the catalyst housing assembly 4 be damaged, and the utility model is welded to support 7 on the awl assembly 5 of outlet side, high temperature is for the destruction of liner when having avoided welding.
As shown in Figure 3, clampshell manifold 2 is divided into go up a slope section 9 and lower slope section 10 along same curved surface.Compared to the tubular manifold design, the manifold design of clampshell can satisfy the spatial arrangement requirement.For the motor of compact type, this advantage is particularly outstanding.
As shown in Figure 4, be provided with flanging 11 respectively at the edge and the air flue place of inlet flange 1.The flanging structure can be so that weld seam away from flange facing, when welding, can reduce the influence of welding for sealing plane, thereby better meet seal request.
As shown in Figure 5, inlet flange 1 is provided with the sealing surface 12 of projection.In use, the sealing surface 12 of projection can reduce the influence of thermal distortion, thereby reaches better sealing effect.
