Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of turbosupercharger exhaust gas bypass valve actuator pull bar.
Background technique
Along with growth in the living standard, automobile has obtained popularizing greatly as a kind of traffic tool.Yet under the situation that whole world energy day is becoming tight and the environmental protection cry is day by day surging, people have proposed increasingly high requirement to the energy-saving and emission-reduction performance of motor car engine.Automobile industry is just taking to respond actively measure at present, and wherein motor employing turbocharging technology raising energy-saving and emission-reduction performance is exactly one of important behave.
The waste gas inertia impulsive force that turbosupercharger utilizes motor to discharge promotes the turbine in the turbine chamber, and turbine drives coaxial wheel rotation again, and the air that the impeller compression is sent here from the air-strainer pipeline makes it to get into cylinder after the supercharging.When engine speed speeds; The waste gas velocity of discharge and secondary speed also speed synchronously; Impeller just can the force feed more air get into cylinder, and the pressure of air and density increase can make fuel combustion more abundant, the corresponding calorific value that increased; So just can under the prerequisite that does not increase fuel, improve the output power and the moment of torsion of motor, thereby improve the engine energy-saving reduction performance.
Yet when turbosupercharger is that the boost pressure that provides of motor is excessive; When having surpassed each item index such as power, moment of torsion, discharging of motor self; To cause turbosupercharger and engine failure, and therefore, also be provided with an exhaust gas by-pass valve on the turbosupercharger and solve the problems referred to above.
Be connected with final controlling element on the exhaust gas by-pass valve, final controlling element is through the switching of pull bar control exhaust gas by-pass valve valve.Mechanical load is unlikely too high when guaranteeing the constant engine operating mode, and the unlikely hypervelocity of turbosupercharger is provided with a pretightening force setting value in final controlling element; When boost pressure during greater than this pretightening force setting value, this pressure can be with the diaphragm jack-up in the final controlling element, and the diaphragm pushing drawing rod moves axially; The mobile of pull bar makes the exhaust gas by-pass valve valve opening, so a part of waste gas does not directly enter atmosphere through pressurized machine, the turbine inlet flow reduced; Turbo charger speed descends; During less than the pretightening force setting value, the spring restoring force pulling pull bar in the final controlling element cuts out exhaust gas by-pass valve up to pressure, thus reach a protection I the effect of pressurized machine and motor.
Turbosupercharger needs to regulate above-mentioned pretightening force setting value in processes such as installation and maintenance; And this pretightening force setting value need be passed through rotating rod; The pull bar that is threaded with the pull bar sleeve is rotated and moves axially, thereby changes the pretightening force setting value in the final controlling element.Yet present final controlling element pull bar basically all is smooth cylindrical body, does not have Point of Strength preferably above, therefore regulates comparatively difficulty.
China's utility application (application number: 200720062730.X) disclose a kind of turbosupercharger actuator pressure vernier device; Comprise that turbine box assembly, final controlling element cover tubular union, two ends are processed with the final controlling element sleeve pipe middleware of left-handed and dextrorotation internal thread, have the final controlling element push rod of right-handed thread locking nut; Final controlling element cover tubular union and final controlling element push rod adopt with final controlling element sleeve pipe middleware and are threaded, and through left-handed thread locking nut and the locking of right-handed thread locking nut.Vernier device adopts left-handed and right-handed thread regulative mode, left-handedly regulates pretightening force with final controlling element sleeve pipe middleware right-handed thread through rotating to attack at two ends.Though this model utility can be regulated pretightening force, this controlling device structure is comparatively complicated.

Described operation unit is two flat-bottom slots that radial symmetric is provided with on the pull bar.On pull bar, offer flat-bottom slot, easy to process, structural modification is little, does not influence the performance of pull bar itself, and the flat-bottom slot radial symmetric is provided with the clamping of easy-to-operat instrument.
Described operation unit is the circular hole that pull bar upper edge pull bar radially is provided with.Offer circular hole on the pull bar, easy to process, structural modification is little, can realize regulating through in circular hole, inserting operation tool, and is simple to operate.
Described circular hole is a blind hole.Blind hole both can be implemented as the adjusting pretightening force Point of Strength was provided, and reduced simultaneously because on pull bar, punch the influence of pull bar self intensity.
Be axially arranged with strip projected parts always on the circumferential surface of described pull bar.During conciliation, through the rotation of this convexity, operator can know the general angle of pull bar rotation, accomplish to know very well in one's heart.
Described actuator comprises supporting disk, spring and the diaphragm that is connected with pull bar.Supporting disk, spring and diaphragm are the internal structure of final controlling element, and the rotation of pull bar is the pretightening force of regulating this spring.
Compared with prior art, this turbosupercharger exhaust gas bypass valve actuator pull bar has the following advantages:
1, owing to flat-bottom slot is set on pull bar, so the adjusting of pretightening force is convenient.
2, convenient, simple in structure owing to flat-bottom slot is set, so processing cost is low.
