Background technique
Turbosupercharging is a kind of usual way of engine booster, can be used for promoting the power of motor and moment of torsion, reduces motor Pollution drainage, reduces oil consumption.At present, be assemblied in the turbosupercharger of turbosupercharger mainly with exhaust gas by-pass valve of vehicular engine, also the variable geometry turbocharger (VG) having small part more advanced, the final controlling element of these turbosupercharger is all adopt Pneumatic power diaphragm type final controlling element to control the aperture of bypass valve or variable-geometry mechanisms usually, specifically malleation driving and negative pressure can be divided into drive two kinds of modes by pneumatic pressure source.No matter adopt which kind of driving mode, be all utilize gas pressure to act in final controlling element rubber membrane on, regulate bypass valve or variable-geometry mechanisms aperture by rubber membrane compression (malleation driving) or (negative pressure driving) push rod be connected on spring that stretches, final controlling element is turbosupercharger very important control mechanism.The automobile of turbosupercharger is housed, particularly runs on passenger car in city, acceleration and deceleration are relatively more frequent, and this just requires that turbosupercharger can regulate the aperture of bypass valve or nozzle vane in good time accurately, to adapt to the needs of engine load change.In order to improve the control accuracy of final controlling element, reducing the wearing and tearing of the frequent back and forth movement of final controlling element, usually guiding device being set on push rod, control the traffic direction of final controlling element.But guiding device particularly O type circle distance high-temperature turbocharger turbine housing wherein and the high temperature such as gas exhaust manifold and catalyst converter part all closer, easily because of high temperature ageing, cause guiding device accelerated wear test to be lost efficacy, thus affect reliability and the durability of turbosupercharger.
Model utility content
For the defect the utility model overcoming prior art provides a kind of heat-proof device being applied to turbosupercharging final controlling element, reduce the thermal radiation of the high temperature parts such as the turbine case of turbosupercharger.
A kind of heat-proof device being applied to turbocharger actuator that the utility model provides, the push rod comprising final controlling element and be connected with final controlling element, described final controlling element comprises housing and end cap; Described end cap is provided with push rod patchhole; Push rod guiding device is provided with in described housing; Described push rod is fixedly connected with push rod guiding device through push rod patchhole; Described push rod is positioned at outside end cap and thermal baffle is installed.
Further, described push rod guiding device comprises elastic element and guide pad; One end of described elastic element is provided with the limiting board of middle through-hole; Described limiting board is provided with the mounting groove for installing guide pad; The central part of described guide pad is provided with the push rod mounting hole with push rod interference fit.
Further, the diameter of described middle through-hole is greater than the diameter of push rod mounting hole.
Further, described guide pad is disc guide pad; Described mounting groove is disc mounting groove; The excircle of described guide pad offers circular groove; O RunddichtringO is equiped with in described circular groove.
Further, described thermal baffle is disc thermal baffle; The diameter of described disc thermal baffle is greater than the diameter of push rod patchhole.
Further, described thermal baffle is square thermal baffle; The area of described square thermal baffle is greater than the area of push pedal patchhole.

Fig. 2 is push rod guiding device structural representation;
In figure: 1, limiting board; 2, guide pad; 3, thermal baffle; 4, push rod; 5, end cap; 6, O type circle; 7, housing; 8, elastic element.
Embodiment
As shown in Figure 1, a kind of heat-proof device being applied to turbocharger actuator, the push rod 4 comprising final controlling element and be connected with final controlling element, described final controlling element comprises housing 7 and end cap 5; Described end cap 5 is provided with push rod patchhole; Push rod guiding device is provided with in described housing 7; Described push rod 4 is fixedly connected with push rod guiding device through push rod patchhole; Described push rod 4 is positioned at outside end cap 5 and thermal baffle 3 is installed.Described push rod guiding device comprises elastic element 8 and guide pad 2; Described elastic element 8 is spring, and one end of described spring is provided with the limiting board 1 of middle through-hole; Described limiting board 1 is provided with the mounting groove for installing guide pad 2; The central part of described guide pad 2 is provided with the push rod mounting hole with push rod 4 interference fit.The diameter of described middle through-hole is greater than the diameter of push rod mounting hole.Described guide pad 2 is disc guide pad; Described mounting groove is disc mounting groove; The excircle of described guide pad 2 offers circular groove; O RunddichtringO 6 is equiped with in described circular groove.
Described thermal baffle 3 is disc or square, but its disc diameter or area are greater than the diameter of push rod patchhole or the area of push pedal patchhole, ensures that thermal baffle 3 effectively can keep out the thermal radiation from turbosupercharger high temperature part; Will avoid because vibration produces extra noise, outside dimension or area are also unsuitable excessive simultaneously.Described thermal baffle 3 can weld or be fixed by caulking on push rod 4, selects aluminium sheet or the material of the good heat-insulation effect such as sheet metal of aluminizing is made.
