Abstract
The utility model discloses a front end awl for urge exhaust apparatus in advance, including front end awl body, front end awl body include in the integral type high pressure fashioned be used for first connecting portion (1) that is connected with the flange, the cone portion (2) that is eccentric truncated conical tip and be used for with second connecting portion (3) of urging carrier portion to be connected in advance, first connecting portion (1) and second connecting portion (3) all be cylindric, just the diameter of second connecting portion (3) be 1.5-1.8 times of diameter of first connecting portion (1), the contained angle theta of first connecting portion (1) place axis and vertical direction be 8-10, the surface of cone portion (2) be equipped with circular shape mounting hole (5), just the periphery of mounting hole (5) be equipped with annular platform portion (4). The high pressure is fashioned in this a front end awl for urge exhaust apparatus in advance, the design is more equitable, can improve carrier edge air current relatively, and the exhaust velocity of flow is abundant even.
Description
Technical field
The utility model relates to automobile exhaust system field, particularly a kind of for urging the front-end-cone of venting gas appliance in advance.
Background technique
Urge venting gas appliance in advance, be mounted in most important outer purifier in automobile exhaust system, the harmful gases such as CO, HC and NOx that vehicle exhaust can be discharged by it change harmless carbon dioxide, water and nitrogen into by oxidation and reduction, become innocuous gas by harmful gas, vehicle exhaust is purified.Front-end-cone is as one of heavy connection of urging venting gas appliance in advance, and at present, the front-end-cone of prior art adopts an angle of flare, and this structure is simple, easy to process, and it is comparatively even to adopt the less angle of flare that air-flow can be made to arrive the speed before carrier.But when exhaust flow rate is very fast, especially when high engine speeds or large load, the front-end-cone of prior art makes most of exhaust airstream by the center region of carrier, and that carrier edge air-flow passes through is relatively less, whole carrier is made to be not fully utilized like this, aging very fast in carrier center region, and carrier center regional temperature is higher, cause and there is larger temperature gradient along carrier radial direction, produce thermal stress distribution uneven, easily cause carrier thermal distortion to damage.Due to the restriction of processing mode and physical dimension, the front-end-cone structure of prior art does not reach the full and uniform ideal effect of exhaust flow rate.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of inner high voltage shaping, design more reasonable, can relatively improve carrier edge air-flow, the front-end-cone for urging venting gas appliance in advance that exhaust flow rate is full and uniform.
The technical scheme in the invention for solving the above technical problem is: a kind of for urging the front-end-cone of venting gas appliance in advance, comprise front-end-cone body, described front-end-cone body comprise integral type inner high voltage shaping for be connected with flange the first joint, cone part in eccentric circle cone table shape and for second joint of urging carrier portion to be connected in advance, all cylindrically, and the diameter of the second described joint is 1.5 ~ 1.8 times of the diameter of the first joint for the first described joint and the second joint; The first described joint place axis and the angle theta of vertical direction are 8 ~ 10 °, and the outer surface of described cone part is provided with circular mounting hole, and the periphery of described mounting hole is provided with the platform part of annular.
Compared with prior art, the utility model has the advantage of: this be used for urging in advance the front-end-cone of venting gas appliance comprise integral type inner high voltage shaping for be connected with flange the first joint, cone part in eccentric circle cone table shape and for second joint of urging carrier portion to be connected in advance, first joint and the second joint are all cylindrically, the diameter of the second joint is 1.5 ~ 1.8 times of the diameter of the first joint, and the angle theta of the first joint place axis and vertical direction is 8 ~ 10 °.Like this, the design of this front-end-cone is more reasonable, and can relatively improve carrier edge air-flow, exhaust flow rate is full and uniform.The outer surface of cone part is provided with circular mounting hole, and like this, this mounting hole can be utilized to install lambda sensor etc., and the periphery of mounting hole is provided with the platform part of annular, it is more firm to install, convenient fixing.
As preferably, the axis of described mounting hole and the angle α of substantially horizontal are 25 ° ~ 30 °.Like this, the setting of mounting hole is more reasonable, is also more conducive to measure if install lambda sensor.
As preferably, the axis of described mounting hole and the angle α of substantially horizontal are 26 °.Like this, the setting of mounting hole is more reasonable, is also more conducive to measure if install lambda sensor.
As preferably, the first described joint place axis and the angle theta of vertical direction are 8 °.
As preferably, the mounting hole place described in the correspondence of lower end of the second described joint is provided with the breach for locating.Like this, the installation of front-end-cone is more convenient to.
