As shown in Fig. 2-1 and 2-2, initiatively composite brake disc 8 is hollow cylinder, and its body is made up of active friction brake material 13.Active friction brake material 13 chooses sintered alloy friction material or carbon fiber friction material.Even number groove is along the circumferential direction had in the side of active composite brake disc 8.Positive pole triboelectricity material 9 and negative pole triboelectricity material 10 is fixed with in groove.Wherein, the layout of positive pole triboelectricity material 9 and negative pole triboelectricity material 10 is alternate.The shape of groove is the one in rectangle, fan-shaped or circle.
As shown in Fig. 3-1 and 3-2, passive composite brake disc 3 is also hollow cylinder, and its body is made up of passive friction braking material 14.Passive friction braking material 14 chooses the larger metallic material of intensity or alloy material.Along the circumferential direction have even number groove in the side of passive composite brake disc 3, in groove, be fixed with main pole triboelectricity material 11.The number of recesses of passive composite brake disc 3 is identical with the number of recesses of active composite brake disc 8, and shape is identical with size.
Common brake disc 12 is hollow cylinder, and its body is made up of passive friction braking material 14.
According to electrostatic friction effect, after positive pole triboelectricity material 9 and main pole triboelectricity material 11 rub, positive pole triboelectricity material 9 is positively charged, and main pole triboelectricity material 11 is electronegative.And after negative pole triboelectricity material 10 and main pole triboelectricity material 11 rub, negative pole triboelectricity material 10 is electronegative, and main pole triboelectricity material 11 is positively charged.
Associating Fig. 1, Fig. 2-1, Fig. 2-2, Fig. 3-1 and Fig. 3-2, passive composite brake disc 3 recessing side is mounted opposite active composite brake disc 8 recessing side corresponding thereto, and passive composite brake disc 3 recessing one side surface points to the inner side of wheel hub 1.
As shown in Figure 4, when after passive composite brake disc 3 recessing one side surface with initiatively composite brake disc 8 recessing side surface contact, now passive composite brake disc 3 is followed wheel hub 1 and is constantly rotated, and initiatively composite brake disc 8 does not have rotary motion.Because main pole triboelectricity material 11 and positive pole triboelectricity material 9 and negative pole triboelectricity material 10 constantly rub, make positive pole triboelectricity material 9 positively charged all the time, negative pole triboelectricity material 10 is electronegative all the time, and on main pole triboelectricity material 11, institute electrically chargedly will constantly convert.
When the area of main pole triboelectricity material 11 just in time overlaps with the area of positive pole triboelectricity material 9 or negative pole triboelectricity material 10, all main pole triboelectricity materials 11 equal neutral at this moment, passive composite brake disc 3 does not have braking moment.

As shown in Figure 6, when the area of the main pole triboelectricity material 11 of rear side is about to crossing with the area of negative pole triboelectricity material 10, on each main pole triboelectricity material 11, institute is electrically charged reaches maximum, and main pole triboelectricity material 11 is subject to also reaching maximum with its moving direction opposite effect power.
But after the area of the main pole triboelectricity material 11 of rear side is crossing with the area of negative pole triboelectricity material 10, because the main pole triboelectricity material 11 of rear side rubs with negative pole triboelectricity material 10, make its positively charged amount start to reduce, its reaction force be subject to will be more and more less.When finally reaching state shown in Fig. 4, main pole triboelectricity material 11 does not have electric charge completely, and passive composite brake disc 3 does not have braking moment yet.
The controlling method with the automobile integrated arrestor of the slow function that rubs described in the utility model is specifically described below in conjunction with accompanying drawing.
The automobile integrated arrestor with the slow function that rubs is integrated with two kinds of modes of braking: friction retarder brake and friction catch.
As shown in Figure 7, when use friction retarder brake, linear motor rotor 7 drives initiatively composite brake disc 8 to move right, and makes passive composite brake disc 3 recessing one side surface and active composite brake disc 8 recessing side surface contact.Passive composite brake disc 3 will be subject to friction retarder brake moment.
As shown in Figure 8, when use friction catch, linear motor rotor 7 drive initiatively composite brake disc 8 be moved to the left, make passive composite brake disc 3 non-recessing one side surface and common brake disc 12 and initiatively composite brake disc 8 non-recessing side surface contact, passive composite brake disc 3 is subject to friction catch moment with common brake disc 12.
