[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model motor car engine embodiment 1 a structural representation.
Fig. 2 is that A among Fig. 1 is to view.
Fig. 3 is the utility model motor car engine embodiment 2 a structural representation.
[embodiment]
In the embodiment 1 of Fig. 1, the utility model motor car engine shown in Figure 2, motor car engine comprises crank pulley 2, air-conditioning generator and the generator support 7 of body 1, bent axle, cast iron or cast steel.Body 1 comprises cylinder body and timing gear housing.The air-conditioning generator is a magneto external rotor direct current air-conditioning generator, and the housing 201 of the annular of crank pulley 2 is as the part of air-conditioning generator external rotor.
The rear end of crank pulley 2 is fixed on the front end axle 801 of bent axle through nut 6.The permanent magnet 3 of forming air-conditioning generator external rotor N, S magnetic pole is fixed on the inwall of crank pulley housing 201, and the housing 201 of crank pulley annular is as the yoke of rotor.
The stator of air-conditioning generator comprises winding 4 and stator axis 5, and stator axis 5 is passed through needle roller bearing support by bent axle.There is the supporting axle 802 that is used for supporting stator the front of crankshaft front end axle 801.There is support holes 501 at the center of air-conditioning generator unit stator axle 5, and supporting axle 802 is inserted in the support holes 501, and needle bearing 6 is installed between supporting axle 802 and the support holes 501.
Generator support 7 comprises carriage 701 and fore poppet 702, and fore poppet is fixed on the front portion of carriage 701 through screw 10, the rear portion of carriage 702 through screw on frame 1.
The front end of stator axis 5 is axle journals 502 of non-circular cross-section, and the cross section of the axle journal 502 of non-circular cross-section can be the Any shape except that circular, and like ellipse, spline shape, rectangle, triangle or the like, in the present embodiment, the cross section of axle journal 502 is a rectangle.Fore poppet 702 has the hole 703 with the suitable non-circular cross-section of axle journal 502, is convenient to axle journal 502 and inserts, and stop stator axis 5 when work, to be rotated.In order to remedy assembly error, avoid the stator of air-conditioning generator is produced unnecessary constraint, leave enough gaps between axle journal 502 and the hole 703.
