Abstract

The invention relates to a connection structure of an exhaust pipe of an automobile, which comprises a first exhaust pipe, a second exhaust pipe and a hoop, wherein a boss is arranged at a port of the first exhaust pipe in a circumferential direction; an outward flange is arranged at a port of the second exhaust pipe in the circumferential direction; the port of the first exhaust pipe is positioned in the port of the second exhaust pipe; the internal surface of the flange is contacted with one side of the boss; and the hoop is hooped and sleeved on the boss and the flange at a connection port of the first exhaust pipe and the second exhaust pipe. The connection structure has the advantages of high bearing capacity, reliable sealing performance, and no limitation of arrangement space when arranged.

Description

A kind of automobile exhaust pipe connecting structure
Technical field
The present invention relates to the mounting connection structure of the outlet pipe of automobile, particularly automobile exhaust pipe.
Background technique
Automobile exhaust pipe is positioned at the bottom of automobile, is the toxic emission passage of motor car engine.Because the space, chassis of car is extremely limited, when determining the form that outlet pipe connects, need considers whether its spatial joint clearance and car load assembly technology meet the requirements, and will guarantee the sealing of joint between the outlet pipe tube and tube.
The outlet pipe Placement is mostly for flange plate connects at present, and part adopts the pipe that inserts the band cut to connect, and fastening with flat clip.Its advantage of the connection of flange plate mode is that structural strength is big, has certain bearing capacity, and sealability is reliable, but, it could realize because of needing two flanges, and need increase gasket seal betwixt and could guarantee sealing, flange plate and pad all need independent processing, so its cost is higher relatively; On arranging, flange plate is generally big than caliber, so need bigger installing space, just can not meet the demands in this Placement of some special narrow space.And the pipe ways of connecting is simple in structure, and assembly technology is better, is not subjected to the restriction of arrangement space and assembly technology, and manufacture cost is relatively low, and shortcoming is that sealing is relatively poor, and is higher to processing circularity and required precision.
Summary of the invention
The purpose of this invention is to provide a kind of automobile exhaust pipe connecting structure, make it have stronger bearing capacity and reliable sealing performance, be not subjected to the restriction of arrangement space during installation.
Automobile exhaust pipe connecting structure of the present invention, comprise downtake pipe, second exhaust pipe and clip, downtake pipe is connected by the clip installation in its port with second exhaust pipe, downtake pipe circumferentially is provided with boss in its port along it, second exhaust pipe circumferentially is provided with outside flange in its port along it, the downtake pipe port is positioned at the second exhaust pipe port, one contacts side surfaces of the internal surface of described flange and described boss, the clip hoop is enclosed within first, on the boss and flange at place, second exhaust pipe connecting port, the outer surface of downtake pipe port and the internal surface of second exhaust pipe port are fitted.
The cross section of described boss is V-shaped, and described flange makes second exhaust pipe port flare, and the internal surface of clip is V-shaped, fits with the outer surface of described flange and the another side of described boss respectively in its both sides.
Clip is made up of band, garter spring, screw rod and nut, and an end of screw rod is fixed on an end of band, and the other end of screw rod passes from the other end of band, and nut is screwed on the screw rod, and garter spring is welded on the internal surface of band, and its cross section and internal surface are all V-shaped.
Described garter spring is divided into separate three sections, and it is evenly arranged in the internal surface of band, is separated with distance between the end face of two neighboring sections garter spring mutually.
During connection, the downtake pipe port is inserted in the second exhaust pipe port, and make a contacts side surfaces of the internal surface and the downtake pipe port boss of second exhaust pipe port flange, then the clip hoop is enclosed within on the flange and boss of first, second outlet pipe port joint, clip is fastening, and then downtake pipe is realized being connected with second exhaust pipe.
Linkage structure of the present invention is because the downtake pipe port is to be inserted in the second exhaust pipe port, so can improve the bearing capacity that pipe connects, and the flange of its connecting port and boss structure are after by the clip banding, can make between downtake pipe port outer cylinder surface and the second exhaust pipe port inner periphery, between second exhaust pipe port flange internal surface and downtake pipe port boss one side, realize fitting tightly between clip V-arrangement internal surface and second exhaust pipe port flange outer surface and the downtake pipe port boss another side, form the sealing of line or face everywhere at this, thereby guaranteed the reliability of downtake pipe and second exhaust pipe joint sealing, and downtake pipe and the also very difficult under external force disengaging of second exhaust pipe.Number of spare parts of the present invention is few, and is simple in structure, mount and dismount all very convenient owing to adopt the pipe ways of connecting, so be not subjected to the restriction of arrangement space during installation.
