[embodiment]
In the embodiment 1 of Fig. 1, motor car engine of the present invention shown in Figure 2, motor car engine comprises body 1, crank pulley 2 and air-conditioning generator.Body 1 comprises cylinder body, timing gear housing and engine support.The air-conditioning generator comprises stator 3, rotor 4, and stator 3 is installed on the rotor shaft 401 through forward and backward bearing 5.The air-conditioning generator is the permanent magnetic DC generator, and the magnetic pole 402 of permanent magnet is arranged on the rotor 4.
Crank pulley 2 is packed on the front end axle of engine crankshaft.
The main body of air-conditioning generator drive shaft 6 is a splined shaft 602, and there is the bead 601 of installation the rear end of air-conditioning generator drive shaft 6.The rotor shaft 401 of air-conditioning generator is a hollow shaft; Its endoporus is a splined hole; The splined hole of the hollow shaft 401 of air-conditioning generator amature is enclosed within on the splined shaft 602 of air-conditioning generator drive shaft 6, is driven by splined shaft 602, and the front end of splined shaft 602 is equipped with set screw nut 603.
Bead 601 is installed is fixed on the front end of crank pulley 2,, locate through centering seam 201 between air-conditioning generator drive shaft 6 and the crank pulley in order to guarantee the coaxality of air-conditioning generator rotor shaft and engine spindle neck through a plurality of screws 604.
The stator 3 of air-conditioning generator is installed on the rotor shaft 401 through forward and backward bearing 5, and both can relatively rotate, and rotates in order to prevent stator, and stator 3 needs fixing.Because in the present embodiment, the rear end of air-conditioning generator drive shaft 6 and crank pulley 2 have adopted and have been rigidly connected, and the shell of stator 3 need be bearing on the stator bracket 7 through elastic element.
The motor car engine of the embodiment of the invention 1 provides electric power through the air-conditioning generator to the on-board air conditioner system; In order to drive the compressor and the blower fan of air-conditioning system; The air-conditioning generator arrangements is in the front portion of motor car engine; Bent axle by motor car engine directly drives, and need not belt drives, and engine structure is simple.Present embodiment is convenient to the on-board air conditioner system and is adopted the integral arrangement structure, and the pipeline of compressor is short, and refrigeration agent is difficult for leaking, and can simplify structure, the raising environmental-protecting performance of on-board air conditioner system.
The embodiment 2 of motor car engine of the present invention shown in Figure 3 and embodiment 1 structural similarity, the main distinction is:
Adopt resilient connection between the rear end of air-conditioning generator drive shaft 6 and the crank pulley 2.The flexible coupling bead 604 in the rear end of air-conditioning generator drive shaft 6; One end of the drive pin 9 of a plurality of elastic coupling flexible couplings is fixed on the wheel rim of crank pulley 2; The other end is inserted in the drive hole of elastic coupling flexible coupling bead 604; Drive air-conditioning generator drive shaft 6 through 1 group of rubber ring 10, the shell of stator 3 directly is fixed on stator bracket 7 through screw 303.
Motor car engine embodiment's 3 of the present invention structure is as shown in Figure 4, is with the main distinction of embodiment 1 and 2:
Axle journal and back axle journal before the front end axle 12 of automobile engine crankshaft comprises, crank pulley 2 is installed on the back axle journal of front end axle 12.The hollow rotor shaft 401 of air-conditioning generator is installed on the preceding axle journal of front end axle 12, is driven by preceding axle journal.
In order to stop stator 3 to rotate, and stator 3 is carried out radial support, supporting structure is with embodiment 1
Because the radially bearing capacity of engine crankshaft front end axle 12 is stronger; Can stator 4 not carried out radial support yet; But in order to stop stator 3 to rotate, embodiment 4 adopts stop pin 13, and stop pin 13 can be fixed on the body 1 or be fixed on the vehicle frame 14 of automobile (as shown in Figure 5).Lock pin aperture 303 is arranged at the bottom of stator 3 shells of air-conditioning generator, and stop pin 13 inserts lock pin aperture 303, stops stator 3 with respect to rotor 4 rotations.
The embodiment's 5 of motor car engine of the present invention structure is as shown in Figure 6; Be with the main distinction of embodiment 3 and 4; The shell of the stator 3 of air-conditioning generator is screwed on the timing gear case of body 1; The hollow shaft 401 of the rotor of air-conditioning generator is installed on the back axle journal of front end axle 12 of automobile engine crankshaft, is driven by the back axle journal of the front end axle 12 of automobile engine crankshaft.Crank pulley 2 is arranged in the place ahead of air-conditioning generator, is installed on the preceding axle journal of front end axle 12 of automobile engine crankshaft, is driven by preceding axle journal.
Present embodiment is because the shell of the stator of air-conditioning generator is screwed on the timing gear case of body; The rotor of air-conditioning generator is installed on the front end axle of automobile engine crankshaft; So no longer bearing need be installed between stator and the rotor; Simplify the air-conditioning generator Structure, shortened the length of air-conditioning generator.Compare with embodiment 1-4, embodiment's 5 structures are the simplest, and the length of motor is also the shortest, but need carry out bigger change to motor, especially will the front end axle of bent axle be extended, and timing gear case is designed again; And the advantage of embodiment 1 and 2 is and need not does big change to motor car engine, can easily utilize existing motor car engine to reequip.
