Abstract
The utility model belongs to the technical field of machinery, provides a turbocharger for motorcycles, and solves the problems of large volume and less compact structure of the conventional turbocharger for motorcycles. The turbocharger for motorcycles includes a volute, a pressure shell, an impeller and an intermediate, wherein a turbine shaft, a bushing and a sealing seat are mounted in the intermediate, a shaft seal is hermetically mounted between the sealing seat and the turbine shaft, a floating bearing sheathing the turbine shaft and used for supporting the turbine shaft and the impeller is mounted in the bushing, the impeller and the turbine shaft are in clearance fit and are fixedly connected through a self-locking nut, and the intermediate is in transition fit with the bushing. The turbocharger for motorcycles has the advantages of small size, compact structure and high rotation speed.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of pressurized machine, particularly a kind of motor vehicle turbocharger.
Background technique
According to present, turbosupercharger is main with the automobile use still, and automobile is all bigger with the pressurized machine volume, and the motor vehicle turbocharger also can reach the purpose that increases power minimizing discharging and fuel consumption.The motor of motorcycle own is less, and discharge capacity is also little, requires the volume of turbosupercharger to want compact, and rotating speed is higher, has therefore developed certain degree of difficulty.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed that a kind of volume is little, compact structure, motor vehicle turbocharger that rotating speed is high.
The purpose of the utility model can realize through following technical proposal: a kind of motor vehicle turbocharger; Comprise volute; Pressure shell, impeller and intermediate are equipped with turbine shaft, lining and sealing seat in the described intermediate, be sealed and installed with the axle envelope between described sealing seat and the turbine shaft; It is characterized in that; Be equipped with in the described lining and be socketed on the turbine shaft and be used for supports turbine shaft and the floating bearing of impeller, described impeller and turbine shaft Spielpassung also are fixed together described intermediate and lining transition fit through self-locking nut.
In above-mentioned motor vehicle turbocharger, little seal ring and big seal ring are installed between described sealing seat and the axle envelope.
Compared with prior art, the support of the turbine shaft in the utility model through the floating bearing in the lining tightened with self-locking nut with after the impeller clearance cooperates; Intermediate and lining are the new structure of transition fit simultaneously; Coaxality is higher, and volume is little, compact structure; Not easy oil leakage also can improve strong impetus under the small-displacement engine of motorcycle situation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, pressure shell; 2, self-locking nut; 3, impeller; 4, axle envelope; 5, turbine shaft; 6, intermediate; 7, lining; 8, floating bearing; 9, sealing seat; 10, little seal ring; 11, big seal ring; 12, volute.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, the Ben Motuo vehicle turbocharger comprises volute 12, pressure shell 1, impeller 3 and intermediate 6, and pressure shell 1 is made up of housing and shell core, and such structure neither influences efficient, can make things convenient for die sinking again.Turbine shaft 5, lining 7 and sealing seat 9 are installed in intermediate 6; Wherein sealing seat 9 has oil-return groove; Oil return is smooth more, is sealed and installed with axle envelope 4 between sealing seat 9 and the turbine shaft 5, and little seal ring 10 and big seal ring 11 are installed between sealing seat 9 and the axle envelope 4; Form double seal like this, sealing effect is more obvious.
In lining 7, be equipped be socketed on the turbine shaft 5 and be used for supports turbine shaft 5 and impeller 3 floating bearing 8, impeller 3 is fixed together with turbine shaft 5 Spielpassung and through self-locking nut 2, intermediate 6 and lining 7 transition fit.
The working principle of motorcycle engine is to be connected with engine exhaust pipe by volute 12; Exhaust flow drives turbine shaft 5 through volute 12, and through the 3 air-breathing actings of transmission impeller, the air inflow of waste gas is many more again for turbine shaft 5; The rotating speed of turbine shaft 5 is also high more; Pressure shell 1 to go out atmospheric pressure high more, directly get into cylinder, form fully burning.
Claims (2)
1. motor vehicle turbocharger; Comprise volute (12); Pressure shell (1), impeller (3) and intermediate (6) are equipped with turbine shaft (5), lining (7) and sealing seat (9) in the described intermediate (6), be sealed and installed with axle envelope (4) between described sealing seat (9) and the turbine shaft (5); It is characterized in that; Be equipped with in the described lining (7) and be socketed in the floating bearing (8) that supports turbine shaft (5) and impeller (2) were gone up and be used for to turbine shaft (5), described impeller (3) is with turbine shaft (5) Spielpassung and be fixed together described intermediate (6) and lining (7) transition fit through self-locking nut (2).
2. motor vehicle turbocharger according to claim 1 is characterized in that, little seal ring (10) and big seal ring (11) are installed between described sealing seat (9) and the axle envelope (4).
