Promote.
Brief description of the drawings
The present invention is further described with implementation method below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the present embodiment；
Fig. 2 is the structural representation of magnetic conductor；
Fig. 3 is the structural representation of magnet；
Fig. 4 is structural representation of the present invention on booster.
Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of many magnetic pole drive devices for being applied to automobile booster that the present embodiment is provided, including with
Magnet 2 that booster rotating shaft 1 is fixedly connected, the magnetic conductor 3, the coil 4 installed in the bottom of magnetic conductor 3 that are set in the outside of magnet 2,
The booster rotating shaft 1 is connected with the hydraulic steering cylinder of booster, and the input of the coil 4 is connected with automobile control end, institute
State magnetic conductor 3 to be fixed on booster shell 5, magnet 2 follows booster rotating shaft 1 to rotate together, the magnetic conductor 3 includes and helps
The base 6 of the connection of power device shell 5, outer magnetizer 7, the interior magnetic conductor 8 in outer magnetizer 7 positioned at the top of base 6, interior,
Spacing is provided between outer magnetizer 8,7 and the ring cavity 9 full of magnetic field is formed, the outer surface of the interior magnetic conductor 8 is provided with ten
Five magnetic poles of projection, the inner surface of outer magnetizer 7 is provided with 15 magnetic poles of projection, and the magnet 2 includes turning with booster
Mounting seat 10 and the magnet ring 11 of the connection of mounting seat 10 that axle 1 is fixedly connected, the magnet ring 11 are provided with 15 magnetic poles, institute above
State magnet ring 11 and rotated in ring cavity 9 and in ring cavity 9.After coil 4 is powered, the magnetic pole of inside and outside magnetic conductor 8,7
Magnetic field is formed in the ring cavity 9, when high-speed running automobile, magnetic field intensity is larger, magnet ring 7 rotate the resistance being subject to also compared with
Greatly, so that steering wheel is more steady, it is impossible to rotate easily；When automobile low cruise, magnetic field intensity is smaller, 7 turns of magnet ring
