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 also consumes more engine power, which worsens the fuel consumption of the engine. economy
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 with a speed change function. A gear III (8) of the mechanical supercharger, which is installed on an input shaft (2), is meshed with a gear IV (21) installed on a driving shaft (16); a driving gear (18) installed on the driving shaft (16) is meshed with a driven gear (10) installed on a driven shaft (12); the input shaft (2) is also provided with a gear I (7) and a clutch mechanism (6) capable of controlling the gear I (7) to rotate and idle; the gear I (7) is meshed with a gear II (22) installed on the driving shaft (16); the driving shaft (16) is provided with a unilateral bearing (20); and the unilateral bearing (20) is set to be a structure capable of controlling the gear IV (21) to rotate and idle. The mechanical supercharger disclosed by the invention has a speed change function, and therefore, the supercharger and an engine can better carry out dynamic characteristic balance at different revolving speeds.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and more specifically relates to 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. Tests have shown that the power and torque of engines using superchargers are increased by an average of 31% to 46%, especially in places with low air density and high altitudes. , to ensure the normal working requirements of the engine, so the use of superchargers is an effective way to improve the power performance, transient performance and emission performance of vehicle engines. [0003] Usually, the supercharger is directly connected to the engine crankshaft by a belt, so the power of the supercharger comes from the engine, and the speed of the supercharger with a fixed speed ratio is a fixed ratio to the engine speed. When the engine is running at a low speed, especially at 1000-2...
