Description

Technical Field

[0001] The utility model relates to the technical field of mechanical superchargers, in particular to an improved mechanical supercharger structure. Background Art

[0002] A supercharger, also known as a supercharger, is a forced air intake device for internal combustion engines. Compared with a turbocharger, the biggest difference lies in the way the air compressor is driven. The turbocharger uses the engine exhaust gas to drive it, while the supercharger uses the torque generated by the engine crankshaft. However, the original design of the supercharger is basically the same as that of the turbocharger, which is to use the air compressor to inhale more air for the engine, and to increase the fuel supply to increase the engine's output power.

[0003] The patent document with the prior art publication number CN215719490U provides an improved supercharger structure, which includes a supercharger housing, a rotor cavity is provided in the supercharger housing, and an air outlet port is provided on the rotor cavity; a drive shaft mounting body and an air inlet port are provided on the supercharger housing; a connecting plate, the connecting plate is provided with two holes coaxial with the two rotors respectively, and a first bearing and a seal are installed in the holes; the connecting plate and the supercharger housing cooperate with each other to form a rotor cavity; a gear top piece, and the gear top piece and the connecting plate together form a gear cavity. The improved supercharger includes a boost actuator and a cooling box, and the supercharger housing, the drive shaft mounting body, the air inlet port, the exhaust port, and the cooling box are integrated into one body and cast at the same time, with a reasonable structural design and compact layout, which improves the efficiency of subsequent processing and assembly and reduces costs.

[0004] However, in the use of the existing supercharger structure, the supercharger is connected to the engine through a belt. Since the supercharger cannot generate power by itself when running, the operation of the supercharger will occupy part of the engine power, thereby increasing the output power and fuel loss of the engine. For this reason, we propose an improved supercharger structure. Utility Model Content
