Abstract

On the brush rocker of the invention a Hall Sensor is mounted and on the motor shaft of rotator set corresponding to the location of Hall Sensor a magnetic ring is sheathed. The case of decelerator is permanently jointed with the gear shaft on which the buffer body is sheathed. On the out side of buffer a buffer gear is sheathed, and on the inner side of buffer a plastic jacket is sheathed. In the inner top portion of the buffer body there is a spring slot in which a buffer spring is mounted, and there is a capping plate gear jointing with the inner top portion of the buffer body and connected with drive gear in mesh. Due to the connection between buffer gear and driven member, and the buffer action of buffer spring, the impact given to the driven member is less. The Hall Sensor can accurately figures out rotation times of electric machine shaft, and is specially suite acceptable for gear shifting in car.

Five, embodiment

Referring to figs. 1 through Fig. 4 as can be known, gear shifting motor of the present invention, comprise the reducing gearbox assembly, the brush holder yoke assembly, rotor assembly, stator module 5, driving gear 12, gear cover plate assembly 11, plug connector 13, blanking cover assembly 20, wherein the reducing gearbox assembly comprises decelerator shell 1, gear shaft 2, the brush holder yoke assembly comprises brush 3, brush holder 4, rotor assembly comprises motor shaft 8, rotor 9, commutator 10, on the brush holder 4 of described brush holder yoke assembly, hall sensor 6 is housed, the wiring of hall sensor 6 is located in the plug connector 13, on the motor shaft 8 of described rotor assembly, be with magnet ring 7 with corresponding position, hall sensor position; The decelerator shell 1 of described reducing gearbox assembly is fixedlyed connected with gear shaft 2, on gear shaft 2, be with buffer main body 14, the outside of buffer main body 14 is with buffer gear 15, the inboard of buffer main body 14 is with plastic sheath 16 (as shown in Figure 2), the inner top of buffer main body 14 has spring groove 17 and buffer spring 18 (as shown in Figure 3, Figure 4) is housed, the inner top of buffer main body 14 is connected with cover plate gear 19, and cover plate gear 19 is meshed with driving gear 12 again.In order to reach better buffering effect, described buffer main body 14, buffer gear 15, plastic sheath 16 constitute all-in-one-piece buffer secondary component and (form integral type through the quadric injection mould shaping, as shown in Figure 2).

Wherein the brush 3 of brush holder yoke assembly is corresponding with commutator 10 positions of rotor assembly; Stator module 5 comprises motor housing, magnetic shoe; 4 wiring are arranged on the plug connector, and as shown in Figure 5: wiring A, B are the wiring of hall sensor, join with electronic controller (ECU) on the automobile; Wiring C, D are respectively anodal, negative pole joins with power supply on the automobile; On gear shaft 2 outsides, be with and clamp back-up ring 21 and link to each other, to fix the buffer main body with buffer main body 14; Cover plate gear 19 is to be enclosed within on the inboard of gear shaft 2, and tightly suppress buffer spring 18 and buffer main body 14, plastic sheath 16 uses (as shown in Figure 2) as the base plate of buffer spring 18, can be according to the watt level of gear shifting motor to select the buffer spring of different model; Described buffer main body 14, buffer gear 15, plastic sheath 16, buffer spring 18, cover plate gear 19 constitute Bunper assembly (as shown in Figure 2).
