Problems solved by technology

When the engine is running at a low speed, especially at 1000-2000rpm, the speed of the supercharger is low, the effect of the supercharger on the engine is not obvious, and the increase in engine power and torque is limited
When the engine is running at high speed, especially at 4000-5000rpm, although the supercharger running at high speed provides a large boost pressure for the engine, it consumes more engine power at the same time, which worsens the fuel economy of the engine.
Therefore, it is difficult for a common supercharger to match the engine well within the full operating range of the engine

Abstract

The invention provides a mechanical supercharger structure, belonging to the technical field of engines. The mechanical supercharger structure with a speed-changing function is characterized in that a front cover plate shell (4) and a bearing plate (10) form a front working cavity; the bearing plate (10) and a rotor shell (14) form a rear working cavity; an input shaft (2) arranged in the front cover plate shell (4) is set into a structure to be a same line with a driving shaft (11) in the rear working cavity; a driving gear (9) arranged on the driving shaft (11) is meshed with a driven gear (17) arranged on a driven shaft (16); the input shaft (2) is also provided with a planetary gear train (7) and a clutch mechanism (6); and the planetary gear train (7) is set into a structure that theplanetary gear train (7) and the front cover plate shell (4) are fixedly arranged and the rotation and the idle rotation of the planetary gear train (7) are controlled by disconnection and connectionof a clutch mechanism (6). In the structure provided by the invention, the speed change of a supercharger can be realized, and good matching of the supercharger and an engine in the range of full working condition can be controlled.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and more specifically relates to a structure of a supercharger with a speed change function. Background technique [0002] A supercharger is a device that pressurizes the air taken in above the normal air pressure. Installing a supercharger is an effective way to improve the power performance, transient performance and emission performance of a vehicle engine. The supercharger is directly driven by the engine through the belt, and the speed of the supercharger with a fixed speed ratio is in a fixed ratio to the engine speed. When the engine is running at a low speed, especially at 1000-2000rpm, the speed of the supercharger is low, the effect of the supercharger on the supercharging of the engine is not obvious, and the improvement of engine power and torque is limited. When the engine is running at high speed, especially at 4000-5000rpm, although the supercharger running at high spe...
