The utility model content
Technical problem to be solved in the utility model provides a kind of motor vehicle alternator rotor of the easier assembling of pin configuration of rotor bus bar.
The technical scheme that its technical problem that solves the utility model adopts is: motor vehicle alternator rotor, comprise installation shaft, the a pair of pawl utmost point, collector ring, extremely be fixed with flabellum at the pawl near collector ring one end, be provided with the axis hole that mates with installation shaft on the pawl utmost point and the flabellum, be provided with two crossed beam trunkings on the end face of that the described pawl utmost point is relative with flabellum, each bar crossed beam trunking all extends to its axis hole by the inter-claw space of the pawl utmost point, is provided with the opening corresponding to crossed beam trunking the inner on the flabellum.
Described opening is the breach that is arranged on the axis hole inner rim of flabellum.
Described opening is that the diameter of flabellum is greater than the axis hole of installation shaft diameter.
The bottom rounding of described inter-claw space.
Described two crossed beam trunkings are with respect to symmetrical centered by the center line of the pawl utmost point.
Described crossed beam trunking is the Face Flow Field on Radial Groove that is positioned at the extreme face of pawl.
The beneficial effects of the utility model are: simple and easy to do, simplified the lead-in wire assembling process, and simplified the processing of the pawl utmost point and flabellum, also can reduce the useless part rate of part.

Be outstanding key structure of the present utility model, all the other rotor structures such as excitation mechanism, installation shaft, collector ring, lead-in wire etc. do not draw in Fig. 2, Fig. 3.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Motor vehicle alternator rotor comprises installation shaft, by the excitation mechanism that coil windings, skeleton, a pair of pawl utmost point consist of, collector ring, flabellum.Such as Fig. 1, Fig. 2 and shown in Figure 3, in the utility model, be fixed with flabellum 2 at the pawl utmost point 1 near collector ring one end, be provided with the axis hole 11 with the installation shaft coupling on the pawl utmost point 1, also be provided with the axis hole 12 with the installation shaft coupling on the flabellum 2, be provided with two crossed beam trunkings 3 on the end face of that the described pawl utmost point 1 and flabellum 2 are relative, each bar crossed beam trunking 3 all extends to its axis hole 11 by the inter-claw space 10 of the pawl utmost point 1, is provided with the opening corresponding to crossed beam trunking 3 the inners on the flabellum 2.The inner of crossed beam trunking 3 refers to it near an end of axis hole 11, and is corresponding, and the outer end of crossed beam trunking 3 refers to that it is near an end of inter-claw space 10.If open the via hole corresponding with crossed beam trunking 3 at flabellum 2, still need the threading via hole when then assembling fan 2, and can not avoid secondary punching, then the purpose of this utility model can't realize fully.
During assembling, at first lead-in wire is walked around the inter-claw space 10 of the pawl utmost point 1 and snapped in the crossed beam trunking 3, then flabellum 2 is installed on the pawl utmost point 1, thereby the end face that lead-in wire is fixed on by crossed beam trunking 3 and flabellum 2 limits in the through wires hole that forms, need not on the pawl utmost point 1 and flabellum 2, to bore a hole separately with anchor leg again, also need not between collector ring and flabellum 2, to increase the fixed structure of lead-in wire, therefore easy to assembly.
As shown in Figure 2, when the wire casing that is provided with on the installation shaft along the installation shaft Axis Extension, the aperture can be arranged on the breach 21 of axis hole 12 inner rims of flabellum 2, and the crossed beam trunking 3 that is exposed by breach 21 places consists of the through wires hole aperture adjacent with installation shaft.In addition, as shown in Figure 3, also can consist of the aperture so that groove 3 exposes by the axis hole 12 of suitable expansion flabellum 2, because the aperture is little, lead-in wire is drawn the rear installation shaft that naturally reclines by the aperture.But no matter be the axis hole aperture that increases opening 21 or enlarge flabellum 2, all only need when the axis hole of stamping-out flabellum 2, to change the shape of drift, and need not to increase the step of stamping-out.
Compare with existing structure, only need to be on the pawl utmost point 1 moulding crossed beam trunking 3, the axis holes 12 of flabellum 2 itself slightly done to be out of shape get final product.Compare with existing drilling technology, in the utility model the required precision of through wires hole low, need not to increase extra punching step, easy-formation more in the impact forging moulding, the part that can avoid the punching distortion to cause is scrapped, and can reduce the useless part rate of part, simplifies the processing of the pawl utmost point and flabellum.
Preferably to the bottom rounding of inter-claw space 10, hurt when sliding onto inter-claw space 10 bottom in order to avoid go between.
Preferred described two crossed beam trunkings 3 are conducive to the dynamic balancing of installation shaft with respect to symmetrical centered by the center line of the pawl utmost point 1.
Because lead-in wire is soft, so the center line of crossed beam trunking 3 can be circular arc, shaped form, or other shape of extending along the pawl utmost point 1 end face.For simplicity, described crossed beam trunking 3 is for being positioned at the Face Flow Field on Radial Groove of the pawl utmost point 1 end face.The position of crossed beam trunking 3 arranges by concrete lead-in wire position, and in example as shown in Figure 2, two crossed beam trunkings 3 are positioned on the same diameter.
