Abstract
The utility model discloses a shell structure of car particle trap, its characterized in that: half shell and the second half shell that equals including the internal diameter, wherein the one end of half shell has first connecting port, the other end of half shell has reducing portion or hole enlargement portion, and this reducing portion or hole enlargement portion can correspond and stretch into in the half shell of second or cup joint in on the half shell of second to half shell welded connection becomes spindle-shaped structure with this second, the half shell other end of second still has the second connector. The beneficial effects of the utility model include: the structure is simple, the design space is saved, the use of parts such as an end cone is reduced, the cost is saved, the integrally formed connecting strength is better, and the service life is longer.
Description
Technical Field
The utility model relates to an automobile exhaust processing apparatus field, concretely relates to shell structure of car particle trap.
Background
A particulate trap is a ceramic filter installed in the exhaust system of a diesel engine that traps particulate emissions before they enter the atmosphere.
The particle catcher shell in the prior art is mostly formed by welding and connecting a plurality of parts or connecting the parts by bolts, and has the disadvantages of complex structure, poor connection strength and short service life.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a shell structure of an automobile particle catcher, which has simple structure, saves the assembling method of multiple components, saves the cost and prolongs the service life of the particle catcher.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a shell structure of car particle trap which characterized in that: half shell and the second half shell that equals including the internal diameter, wherein the one end of half shell has first connecting port, the other end of half shell has reducing portion or hole enlargement portion, and this reducing portion or hole enlargement portion can correspond and stretch into in the half shell of second or cup joint in on the half shell of second to half shell welded connection becomes spindle-shaped structure with this second, the half shell other end of second still has the second connector.
Further, the first half shell and the second half shell are both of thin-wall structures which are integrally formed.
Further, the length of the reduced diameter portion is one quarter of the length of the first half shell.
The beneficial effects of the utility model include: the structure is simple, the design space is saved, the use of parts such as an end cone is reduced, the cost is saved, the integrally formed connecting strength is better, and the service life is longer.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
A shell structure of an automobile particulate trap as shown in fig. 1, comprising a first half shell 1 and a second half shell 2 having the same inner diameter, wherein one end of the first half shell 1 has a first connection port 3 for connecting an air inlet pipe; the other end of the first half-shell 1 is provided with a reducing part or an expanding part, and the reducing part or the expanding part can correspondingly extend into the second half-shell 2 or is sleeved on the outer side of the second half-shell 2 and is welded with the second half-shell 2 to form a spindle-shaped structure. First half shell 1, second half shell 2 are integrated into one piece's thin-walled structure still need encapsulate the particle trap carrier respectively in first half shell 1 and second half shell 2 before welded connection, the second half shell 2 other end still has second connector 4 for connect the outlet duct.
In order to connect the first half-shell 1 and the second half-shell 2 more stably, the length of the reduced diameter portion or the expanded diameter portion is one fourth of the length of the first half-shell 1.
In this embodiment, the diameter reducing portion or the diameter expanding portion is provided with a sensor mounting opening 5 which is radially communicated with the inside of the first half-shell 1.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
Claims (3)
