Mechanical supercharger structure with speed-increasing and shock-absorbing functions

Abstract

The invention provides a mechanical supercharger structure with speed-increasing and shock-absorbing functions, and can be applied to the technical field of engines. A front cover plate assembly (43) of the mechanical supercharger structure is provided with an input shaft (8) in a front cover plate (10), a bearing plate assembly (44) is provided with a driving shaft (27) and a driven shaft (24) in a bearing plate (22), an input gear (18) and an output gear (31) are respectively installed on an intermediate shaft (17) and the driving shaft (27), the intermediate shaft (17) is meshed with the driving shaft (27) by an input gear (18) and an output gear (31), a driving gear (30) and a driven gear (19) are respectively installed on the driving shaft (27) and the driven shaft (24), and the driving shaft (27) and the driven shaft (24) are meshed through the driving gear (30) and the driven gear (19). The mechanical supercharger structure provided by the invention can reduce the damage on theengine from the supercharger caused by emergency brake.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and more specifically relates to a supercharger structure with speed-up and shock-absorbing functions. Background technique [0002] Mechanical supercharging is a common method of engine supercharging. Through mechanical supercharging, the air-fill density and air-fill volume entering the cylinder of the internal combustion engine can be increased. With the good cooperation of the fuel supply system, more fuel can be fully burned. So as to achieve the purpose of increasing the average effective pressure of the internal combustion engine, increasing the power and improving the economy. The supercharger is driven by the engine through the pulley. During the operation of the car, the car needs to be frequently started, stopped, accelerated, decelerated, etc., and the speed of the supercharger is also changed frequently. The fluctuation will cause the belt to bounce greatly. At this time,...

AI Technical Summary

Problems solved by technology

The supercharger is driven by the pulley on the engine through the belt. Affected by the space layout of the engine, the diameter of the driving pulley on the engine should not be too large, while the diameter of the driven pulley installed on the supercharger is affected by the wrap angle of the belt. The diameter of the driven pulley cannot be too small, so the speed ratio between the supercharger and the engine is limited, and the supercharging effect of the engine is also limited.
