Abstract

The invention provides a different-shaft acceleration turbocharger comprising an air pumping impeller, an air compression impeller, a driving shaft, a driven shaft and a final shaft. The air pumping impeller drives the driving shaft at the right end to rotate. A floating bearing and a thrust bearing are fixed to the two ends of the driving shaft. A driving gear is fixed to the right end. One finalshaft is arranged at the right end of the same horizontal plane of the driving shaft. A floating bearing and a thrust bearing are fixed to the two ends of the final shaft, and a final shaft gear is fixed to the left end. The air compression impeller is connected to the right end of the final shaft. The driven shaft is fixed to the right end of the driving shaft and the upper portion of the left end of the final shaft. Floating bearings are fixed to the two ends of the driven shaft, and a first driven gear and a second driven gear are installed on the inner sides of the two ends correspondingly. The first driven gear and the driving gear are in meshed connection. The second driving gear and the final shaft gear are in meshed connection. A gear transmission mode is adopted, the rotation speed is adjusted according to an engine and through the characteristics of the turbocharger, and best operation of the engine is achieved.

Description

technical field [0001] The invention relates to a supercharger, in particular to a turbocharger with different shaft speed increasing. Background technique [0002] The existing turbocharger responds slowly to the sudden change of the throttle. When the engine is at low speed or idling, the turbocharger blades are limited by the exhaust impact frequency, and the speed is not enough to provide sufficient intake pressure. On the contrary, the turbine blades at the compressor end It becomes an air intake obstruction during rapid acceleration, causing turbo lag and an abrupt driving experience. And it will be difficult to master for ordinary driving, driving difficulty and even potential safety hazard. Because the vane turbocharger determines the compressed air volume by the high-speed extrusion of the compressor blades, the higher the speed, the greater the pressure. When the engine is at low speed or idling, the engine exhaust gas is limited by the exhaust impact frequency, ...
