Embodiment Construction

[0014] exist figure 1 , figure 2 In the shown embodiment 1 of the automobile engine of the present invention, the automobile engine includes a body 1 , a crankshaft, a crankshaft pulley 2 of cast iron or cast steel, an air conditioner generator and a generator bracket 7 . The machine body 1 includes a cylinder block and a timing gear housing. The air conditioner generator is a permanent magnet outer rotor DC air conditioner generator, and the ring-shaped casing 201 of the crankshaft pulley 2 is used as a part of the outer rotor of the air conditioner generator.

[0015] The rear end of the crankshaft pulley 2 is fixed on the front end shaft 801 of the crankshaft by a nut 6 . The permanent magnets 3 forming the N and S magnetic poles of the outer rotor of the air-conditioning generator are fixed on the inner wall of the crankshaft pulley housing 201, and the annular housing 201 of the crankshaft pulley serves as the yoke of the rotor.

[0016] The generator bracket 7 includ...

Abstract

The invention discloses an automobile engine, which comprises an engine body, a crank shaft, a crank shaft belt wheel, a power generator and a power generator bracket, wherein the power generator is a permanent magnet outer rotor direct current power generator; a shell of the crank shaft belt wheel is used as a magnetic yoke of a rotor; a permanent magnet of the rotor of the power generator is fixed on the inner wall of the shell of the crank shaft belt wheel; a stator of the power generator comprises a winding and a stator shaft; the stator shaft of the power generator is supported by the front end of the crank shaft and the crank shaft belt wheel through a bearing; and the front end of the stator shaft is connected with the power generator bracket. The automobile engine can supply power to a vehicle-mounted air conditioning system; an air conditioner power generator is arranged at the front end of the crank shaft of the automobile engine, and is not required to be driven by a belt; and the engine has a simple structure, so that the vehicle-mounted air conditioning system has a whole arrangement structure.

Description

[technical field] [0001] The invention relates to automobiles, in particular to an automobile engine capable of providing power for electric equipment such as automobile air conditioners. [Background technique] [0002] The non-independent air-conditioning system used in traditional large and medium-sized buses adopts a split arrangement. The air-conditioning compressor is installed at the front end of the engine and is driven by the crank pulley. The air-conditioning fan is also powered by a DC24V generator driven by the crank pulley of the engine. The disadvantages of the split arrangement of the vehicle-mounted air-conditioning system are that the system structure is complicated, and the pipeline of the compressor is very long, which is likely to cause refrigerant leakage and pollute the environment; the structure of the car engine is complex, and the crankshaft pulley needs to drive many accessories, which is prone to failure. [Content of the invention] [0003] The te...
