Abstract
The invention discloses a combined support used for fixing coolers of an exhaust gas recirculation system. The combined support is structurally characterized in that a groove hole is formed in the upper end of a support body, two EGR cooler installation holes are formed in the lower end of the groove hole, a short round column is arranged below the installation holes, and a screw hole is formed in the center of the short round column. A boss with a screw hole is arranged in the middle of the support body. A long round column is arranged below the boss and a screw hole is formed in the center of the long round column. A screw hole for fixing a support of a flywheel rotation speed sensor harness is arranged below the long round column. The support body is fixed to an engine body through the three screw holes in the lower end. The screw holes in the center of the short round column and the boss are used for fixing two supports of a camshaft phase sensor harness respectively. The screw hole of the long round column is used for fixing a support of an intra-cylinder harness. An integrated structure is adopted in the combined support, the use rate of a single part is increased, multiple use functions are achieved through the combined support, the EGR coolers are installed, and meanwhile the harnesses of three components can be fixed.
Description
Technical field
The invention belongs to engine components, be specifically related to a kind of compound rest of supporting engines cooler for recycled exhaust gas.
Background technique
Along with the continuous enhancing of environmental consciousness and the raising day by day of engine exhaust emission standard, current engine emission requirements reaches the phase III, major part producer adopts high-pressure common rail+cooling EGR (gas recirculation system)+DOC (oxidation catalytic converter)+POC (particulate oxide catalyst converter) scheme, substantially becomes the preferred option that diesel engine is up to standard.Wherein EGR (EGR) technology is widely used in auto manufacturing mostly, and its implication from the tail gas of discharge, leads back portion gas cool, and then enters cylinder reduces the rear particulate matter of burning discharge with this.And cooling EGR adopts external water-cooling pattern mostly, namely a cooler is set before EGR exhaust is lowered the temperature.But owing to being subject to the restriction in external engine space, the support problem of external cooler produces thereupon.Substantially all adopt the sheet metal part of welding to be fixed installation to cooler for recycled exhaust gas at present, this structure is because vibration can cause welding position loose or dislocation that support fracture even occurs in engine operation process, and consequence is unimaginable.In addition the linear speed of electric-control motor gets more and more, and beam positions is fixed bad, except interfering with other parts, very easily because the vibration of motor causes electronic component joint looseness or the damage of wire harness, thus Frequent Troubles.
For solving the problem, the present invention proposes a kind of supporting structure and the problems referred to above can be made to be resolved.
Summary of the invention
The object of the invention is, propose a kind of compound rest for fixing gas recirculation system cooler, the support installation of cooler and the fixing of multiple linear speed support can be met simultaneously.
In order to save the space outerpace of motor, and multiple wire harness is fixing, the technical solution used in the present invention is: the upper end of rack body is provided with slotted eye, the rack body of slotted eye lower end is provided with two cooler for recycled exhaust gas mounting holes, the below of cooler for recycled exhaust gas mounting hole is provided with short cylindrical, and the center of short cylindrical is provided with screw.The middle part of rack body is provided with a boss, and boss face is provided with screw.Be provided with long cylinder in the below of boss, the center of long cylinder is provided with screw.The below of long cylinder is provided with the screw of fixing Speed of Reaction Wheels sensor wire harness bracket, and rack body is fixed by three large screws of lower end and engine cylinder cover.
This compound rest is on the basis of fixed installation cooler for recycled exhaust gas, three wire harness brackets can be fixed, that is: the screw on the screw at short cylindrical center and boss, two supports being used for fixing camshaft phase sensor wire harness respectively, long cylinder screw is used for fixing wire harness bracket in cylinder, and the screw of Speed of Reaction Wheels sensor wire harness bracket is used for fixing Speed of Reaction Wheels sensor wire harness.
Feature of the present invention and beneficial effect are, save the space outerpace of motor, adopt integral structure, a compound rest integrates multiple using function.While meeting cooler for recycled exhaust gas installation, the wire harness of three parts can be fixed, and the hanger of motor is also located on this support.Compound rest adopts the material of QT450-10, avoids and uses welding sheet metal part and cause snap the faults such as fracture.
