Description
Technical field
The utility model is related to field of turbochargers, and in particular to a kind of exhaust gas bypass actuator of turbocharger.
Background technology
The exhaust gas bypass executing agency of turbocharger is that the core institution of booster obtains to adjust boost pressure
Air inflow needed for engine, this mechanism include two core original papers of diaphragm type actuator and exhaust gas valve.
The diaphragm of actuator is combined by rubber and fabric cord, the effect of rubber be make diaphragm have leakproofness, and
The main function of fabric cord is so that diaphragm is had certain mechanical strength and limit diaphragm deformation.Diaphragm be both sealing element and
It is force-summing element, compensating element, therefore the requirement to diaphragm is to ensure to seal in the course of work, under certain pressure difference,
The flexibility of guarantee period elastic part.Since actuator is close apart from spiral casing of pressure booster, the heat radiation being subject to is very big, actuator film
Piece is easy heated roastingization and fails, very risky.
The prior art has the scheme that heat-insulated catch is installed on the pull rod of actuator, to stop automatic pressure intensifier volute and discrimination
The thermal current that pipe is come out enters inside actuator, to improve the working environment of actuator, protects actuator diaphragm, the party
Case Authorization Notice No. be respectively CN 203742771 U, CN 204476551 U, CN 204899991 U China it is practical new
Have disclosed in type patent, the above patent also discloses heat-insulated catch using welding or riveting or the sides such as interference connection
Formula is fixedly connected on pull rod.But actuator is in enging cabin, is as shown in figure 3, being passed through on holder 10 in pull rod 3
It after tie rod hole 11, then is fixedly mounted over the mount 10 by the bolt 4 positioned at pull rod 3 both sides, is fixedly mounted on pull rod 3
Heat-insulated catch 5 also passes through tie rod hole 11 together with pull rod 3, and this requires the enlarged-diameters of tie rod hole 11 to not less than heat-insulated catch
5 diameter, when the installation of actuator ontology 1 over the mount 10 when, it is exposed from tie rod hole 11 that lower face has a larger area, though
Right heat-insulated catch 5 can stop the heat radiation of a part, but heat radiation is spread in the form of wave, still understands some to spread out
The form penetrated passes through heat-insulated catch 5, directly acts on the exposed lower face of actuator ontology 1 and transmits heat, influences actuator film
The service life of piece.
Invention content
The technical problem to be solved by the present invention is to provide a kind of exhaust gas bypass actuators of turbocharger, can solve
The exhaust gas bypass actuator of certainly existing turbocharger is fixedly connected with heat-insulated catch on pull rod, it is necessary in installation actuator ontology
Holder on setting not less than heat-insulated catch tie rod hole, make the exposed larger area in the lower face of actuator ontology, cause to spread out
The lower face of actuator ontology can be acted directly on by being shot through the part heat radiation of heat-insulated catch, influenced actuator diaphragm and used the longevity
The problem of life.
The utility model is achieved through the following technical solutions：
A kind of exhaust gas bypass actuator of turbocharger, including actuator ontology, the actuator body upper part side wall
Be provided be connected to its inner cavity gas nozzle, bottom be provided with from the outwardly extending pull rod in inner cavity, the pull rod connect coaxially have every
Hot catch, the heat-insulated catch are docked by symmetrical two pieces of arc plates, and every piece of arc plate is coaxially connected with semicircular armful
Hoop, the arc plate and anchor ear inner wall fitting pull rod surface, the anchor ear both ends are respectively arranged with engaging lug, the phase of two anchor ears
Neighboring terminal by through engaging lug bolt connection.
The further scheme of the utility model is that the inner wall of the anchor ear is provided with skid resistant course, it is ensured that anchor ear and heat-insulated gear
The tautness and reliability that piece is connect with pull rod.
The further scheme of the utility model is that the other end of the anchor ear is also associated with the second arc plate, two anchor ears
The second arc plate docking composition the second catch；Second catch further decreases the hot spoke for being diffracted into holder and actuator lower face
The amount of penetrating further improves the working environment of actuator, protects actuator diaphragm.
The utility model compared with prior art the advantages of be：
The arc plate for forming heat-insulated catch is removably attachable to pull rod by anchor ear, need not pass through branch with pull rod
Tie rod hole on frame, pull rod bore dia are kept intact, i.e.,：Match with pull rod diameter, substantially reduces actuator lower end
Bare area, diffraction pass through the heat radiation of heat-insulated catch largely to be blocked by holder, effectively reduce and act directly on actuator
The thermal exposure of lower face preferably improves the working environment of actuator, protects actuator diaphragm；Symmetrical arc plate can appoint
Meaning, which is selected, can both dock the heat-insulated catch of composition, and to reduce the cost of part processing, deposit, use is also very convenient.
