Abstract
The utility model belongs to the field of turbochargers, and particularly relates to an air door mechanism of a turbocharger. The air door mechanism of the turbocharger comprises a turbocharger shell, a bypass valve is provided with an air flow adjusting hole, and an air door mechanism body is arranged on the air flow adjusting hole. The air door mechanism body comprises a cover plate, a shaft sleeve and a pull plate, the cover plate covers the outer end face of the air flow adjusting hole, and the shaft sleeve is connected between a connecting shaft of the cover plate and the turbocharger shell in a sleeved mode. The pull plate is fixed at the end of the connecting shaft, a step hole is formed in the turbocharger shell, a step flange is arranged on the peripheral face of the end of the shaft sleeve, and the step flange is matched with the step hole. The air door mechanism of the turbocharger has the advantages that positioning is more reliable depending on the step face on the turbocharger shell, and meanwhile an opening closing-up mode is used, so that the air door mechanism of the turbocharger is more reasonable and simpler.
Description
Technical field
The utility model belongs to field of turbochargers, specifically a kind of turbosupercharger air door mechanism.
Background technique
The pressurized machine with bypass valve application is wider on the market.The supercharging level of common pressurized machine is subject to turbine size control, and lower at the supercharging level of low speed.Pressurized machine with bypass valve allows to adopt little turbine, and has increased low speed supercharging level.Therefore, become the main flow of market application with the pressurized machine of bypass valve.Be illustrated in fig. 1 shown below, pressurized machine regulates air-flow by gas flow-regulating hole M.Therefore, turbocharger housing, after machining, also needs the air door mechanism of assembling and bypass valve connection, and air door mechanism is made up of three parts: cover plate 1, axle sleeve 2, arm-tie 3.The assembly relation of turbocharger housing and air door mechanism is illustrated in fig. 2 shown below, in working order under, must ensure axle sleeve on turbocharger housing without play, also must ensure under cover plate is in off position, the gas flow-regulating hole M shown in Fig. 1 to be sealed completely.In traditional design proposal, axle sleeve has three kinds of lockings, orientation type, and these three kinds of traditional modes, all have its drawback.
Summary of the invention
The utility model, for the deficiency existing in above-mentioned technology, proposes a kind of simple, to save material turbosupercharger air door mechanism of manufacturing.
The utility model has adopted following technology:
Turbosupercharger air door mechanism, it comprises turbocharger housing, bypass valve is provided with gas flow-regulating hole, and gas flow-regulating hole is provided with air door mechanism, and this air door mechanism comprises cover plate, axle sleeve and arm-tie, cover plate is sealed on the exterior edge face in gas flow-regulating hole, axle sleeve is socketed between the coupling shaft and turbocharger housing of cover plate, and arm-tie is fixed on coupling shaft end, and described turbocharger housing is provided with step hole, the side face of sleeve end is provided with step ledge, and step ledge coordinates with step hole.
Step hole 1 exterior edge face of described turbocharger housing is provided with outward extending chimb, and described sleeve end is provided with axle sleeve step, and chimb is provided with the closing in of shrinking to axle sleeve step.
Described closing in is provided with at least two.
The utility model has the advantages that the step surface location relying on turbocharger housing is more reliable, adopt closing in mode more rationally simple simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation in the gas flow-regulating hole of turbosupercharger;
Fig. 2 is the long splice composition of turbosupercharger and air door mechanism;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is that the H-H of Fig. 3 is to view.
Embodiment
As shown in Figure 3, Figure 4, turbosupercharger air door mechanism, it comprises turbocharger housing 4, bypass valve is provided with gas flow-regulating hole, gas flow-regulating hole is provided with air door mechanism, this air door mechanism comprises cover plate 1, axle sleeve 2 and arm-tie 3, cover plate 1 is sealed on the exterior edge face in gas flow-regulating hole, axle sleeve 2 is socketed between the coupling shaft 1a and turbocharger housing 4 of cover plate, arm-tie 5 is fixed on coupling shaft 1a end, described turbocharger housing 4 is provided with step hole 4a, and the side face of axle sleeve 2 ends is provided with step ledge 2a, and step ledge 2a coordinates with step hole 4a.
Wherein, the step hole 4a exterior edge face of turbocharger housing 4 is provided with outward extending chimb 4b, and described axle sleeve 2 ends are provided with axle sleeve step 2b, chimb 4b is provided with the closing in 5 of shrinking to axle sleeve step 2b, closing up 5 generally has symmetrical two, can have multiple, such as four, six etc.
Axle sleeve is processed by turner, comparatively simple in technique, compared with prior art, has reduced miller operation, has reduced workload, has saved cost.
φ 20 gas flow-regulating holes on turbocharger housing, the processing taking φ 48 holes as benchmark on numerical control milling machine.The positioning hole of axle sleeve is installed on turbocharger housing, on numerical control milling machine, is used mandrel and the processing taking φ 48 holes as benchmark.This technological method is reasonable, simple and reliable, can accurately ensure that air door can be by φ 20 hole sealings after installing.Compared to existing technology, on turbocharger housing, process straight hole simpler than processing tapered hole, more easily ensure tolerance of size, reduced difficulty of processing, also do not need to use special tool, saved man-hour, reduced the cost of charp tool.
Meanwhile, the utility model relies on the step surface location on turbocharger housing, simpler with respect to prior art, more reliable; Locking mode adopts closing in mode, does not need welding, compared to existing technology advantages of simple more.
