Abstract
The utility model discloses an exhaust gas recirculation cooler combined support, which is formed by a main support and a secondary support; the main and secondary supports are right-angle structural members; two through holes and two strip-shaped holes are formed in the top face of the main support; three through holes are formed in the vertical face of the main support; two through holes are formed in the top face of the secondary support; nuts are welded with the two through holes in the top faces of the main and secondary supports respectively; the through hole positions of the secondary support correspond to the two strip-shaped hole positions in the top face of the main support; the main support is fixed with the two through holes of the secondary support by the two strip-shaped holes in the top face through bolts; two strip-shaped holes are also formed in the lower part of the vertical face of the secondary support; gaskets are respectively arranged at the inside faces of the two strip-shaped holes; and reinforcing ribs are respectively welded between the vertical faces and the top faces of the main and secondary supports. The exhaust gas recirculation cooler combined support is very compact in structure and convenient to disassemble; the vibration problem of the thin-wall parts is solved while resonance can be avoided; and the long-term and stable operation of an EGR system can be ensured.
Description
Technical field
The utility model relates to and belongs to engine fittings, is specifically related to a kind of device for the assembling cooler.
Background technique
Along with the increasingly stringent of Abgasgesetz, the most diesel oil motor has all been installed EGR (EGR) cooler and has been controlled the discharging of oxynitrides.Due to the restriction that is subjected to the peripheral installing space of motor, some coolers for recycled exhaust gas are arranged on the outlet pipe top, and this cooler support can only be made into the sheet metal part of thin walled structures.This cooler position vibration very acutely, be attached thereto the also easily fracture of pipeline that connects during except engine operation, whole egr system is caused damage, had a strong impact on the emission performance of motor, its result has been aggravated the pollution to environment.For this reason, have higher requirement for the support that plays firm support (cooler for recycled exhaust gas) effect.The utility model has proposed a kind of comparatively desirable solution accordingly.
Summary of the invention
The purpose of this utility model is to provide a kind of cooler for recycled exhaust gas combined pillar, makes it have enough rigidity, reaches the purpose that suppresses vibration, guarantees the normal operation of egr system.
Below in conjunction with accompanying drawing, theory structure of the present utility model is described.The cooler for recycled exhaust gas combined pillar, fixedly formed by major and minor two supports.Master bracket and assistant support are structure of right angle tyoe spare, and the master bracket end face is provided with two through holes and two bar holes, and the through hole back side is welded with nut.The vertical plane of master bracket is provided with three through holes, is welded with three long stiffening ribs between two vertical surface inboards of master bracket.The assistant support end face is provided with two through holes, and two through hole back sides also are welded with nut, and two bar hole positions of this lead to the hole site and master bracket end face are corresponding, and master bracket is fixed with bolt by two bar holes of end face and two through holes of assistant support.The vertical plane bottom of assistant support also is provided with two bar holes, and the inner side surface of two bar holes respectively is welded with pad, is welded with two short stiffening ribs between assistant support vertical plane outer side surface and end face.
Design principle of the present utility model is, the mounting point that allows according to the motor peripheral space and designing, and combined pillar is divided into major and minor two supports, and its purpose is mainly for convenience detach and don't loses its rigidity.
Characteristics of the present invention and beneficial effect are that structure is very compact, when efficiently solving thin walled structures part vibration problem, can avoid the generation of resonating, and guarantees the operation of egr system long-term stability.The design of the split setting of major-minor support and bar hole, can eliminate alignment error, is convenient to loading and unloading.

Embodiment
Below in conjunction with accompanying drawing and by embodiment, structural principle of the present utility model is described further.Cooler for recycled exhaust gas combined pillar, its structure are that master bracket 1 and assistant support 2 are structure of right angle tyoe spare (as Fig. 1), and the master bracket end face is provided with two through holes and two bar holes, and the through hole back side is welded with nut; The vertical plane of master bracket is provided with three through holes 3, is welded with three long stiffening rib 4(such as Fig. 2, Fig. 3 between two vertical surface inboards of master bracket).The assistant support end face is provided with two through holes, and two through hole back sides also are welded with nut, and two bar hole positions of this lead to the hole site and master bracket end face are corresponding, and master bracket is fixed with bolt by two bar holes of end face and two through holes of assistant support.The vertical plane bottom of assistant support also is provided with two bar holes, and the inner side surface of two bar holes respectively is welded with pad, is welded with two short stiffening rib 5(such as Fig. 1 between assistant support vertical plane outer side surface and end face).The wall thickness of master bracket and assistant support end face and vertical plane is 6mm, and long and short stiffening rib wall thickness is 6mm.
Main bracket structure is that whole forging and stamping form, and in order to ensure master bracket, has higher rigidity, is welded with three road stiffening ribs between the vertical surface of two sides.The structure of assistant support is to have two straight plates to be welded, and in like manner in order to ensure master bracket, has higher rigidity, is welded with two road stiffening ribs between the vertical surface of two sides.Three through holes of master bracket vertical plane, be used for and being connected of engine cylinder cover 6; Two through holes and two bar holes of end face are used for installing cooler for recycled exhaust gas 7(such as Fig. 4), two bar holes also are used for fixing with the combination of assistant support, and can be used to adjust the alignment error of two supports.Be used between two vertical planes of major-minor support outlet pipe 8 is installed, with the mounting hole of the bar hole on assistant support and outlet pipe, with bolt, fix.
