Abstract
The utility model relates to an engine EGR (exhaust gas recirculation) connection tube assembly comprising a tube body which is hollow, a flange connected to one end of the tube body, and a positioning plate connected to the other end of the tube body. A mounting plate in the middle of the tube body, the part, between the positioning plate and the mounting plate, of the tube body and the part, between the flange and the mounting plate, of the tube body are all provided with a plurality of spiral corrugation units. The engine EGR connection tube assembly is simple in structure and quick and simple to position; the engine EGR connection tube assembly and an engine can be quickly positioned and mounted through the flange at one end of the tube body, the positioning plate at the other end of the tube body and the mounting plate in the middle of the tube body, positioning accuracy is good, precision is high, the two corrugation units are arranged on the tube body, deformation is automatically compensated according to the feature that the corrugation units can stretch, compress and twist, stress amplitude is greatly reduced, and fatigue damage of the EGR tube body caused by long-term stressing is avoided.
Description
Technical field
The utility model relates to connecting pipe of engine, relates in particular to a kind of EGR connecting tube assembly for engines exhaust gas recirculation.
Background technique
In engine art, in order to reduce cylinder temperature and to control the ratio of waste gas oxious component, when designed engines combustion system, by EGR EGR, part waste gas is introduced to engine aspirating system.Being located by connecting and comparatively difficulty being installed of the EGR connecting tube of conventional construction and motor, in addition because the vibration of engine system is larger, affects location greatly, makes installation precision be difficult to ensure.
Model utility content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of engine EGR connecting tube assembly is provided, have connect reliable, installation precision is high, vibration damping, the effective advantage of antivibration.
The technological scheme that the utility model adopts is as follows:
A kind of engine EGR connecting tube assembly, comprising inner is hollow body, is positioned at one end adpting flange of described body, the other end connected positioning plate; Be arranged in the part device mounting plate of described body, on the body between described positioning plate and mounting plate and on the body between flange and mounting plate, some spiral ripple groups be all set.
Its further technological scheme is:
In the periphery of described flange, multiple boss that stretch out and form are set, described boss is semicircle, has the first mounting hole at the circle centre position of described boss, between each boss, is connected to form one by arc limit;
Described positioning plate is rectangular plate, has two relative the second mounting holes each other on described positioning plate.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, it is fast and convenient to locate, the mounting plate that utilizes the flange of body one end and the positioning plate of the other end and be positioned at body middle part has effectively been realized quick location and the installation with motor, accurate positioning is good, precision is high, and by two groups of ripple groups are set on body, the feature of utilizing ripple group can stretch, compress and reverse, carries out auto-compensation to amount of deformation, greatly reduce stress amplitude, avoid EGR body because of long-term stressed and tired impaired.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of engine EGR connecting tube assembly, comprising inner is hollow body 3, is positioned at one end adpting flange 1 of body 3, the other end connected positioning plate 5; Be arranged in the part device mounting plate 4 of body 3, on the body 3 between described positioning plate 5 and mounting plate 4 and on the body 3 between flange 1 and mounting plate 4, some spiral ripple groups 2 be all set.As shown in Figure 5, in the periphery of flange 1, multiple boss 101 that stretch out and form are set, boss 101 is semicircle, has the first mounting hole 103 at the circle centre position of described boss 101, between each boss 101, is connected to form one by arc limit 102.In Fig. 5, boss 101 is 3, and the line in each first mounting hole 103 centers of circle forms triangle, has realized installation triangle location, and firm position is reliable.As shown in Figure 4, positioning plate 5 is rectangular plate, has two relative the second mounting holes 501 each other on described positioning plate 5.
The utility model is simple in structure, it is fast and convenient to locate, the mounting plate that utilizes the flange of body one end and the positioning plate of the other end and be positioned at body middle part has effectively been realized quick location and the installation with motor, accurate positioning is good, precision is high, and by two groups of ripple groups are set on body, the feature of utilizing ripple group can stretch, compress and reverse, carries out auto-compensation to amount of deformation, greatly reduce stress amplitude, avoid EGR body because of long-term stressed and tired impaired.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
