Abstract
A high-speed brushless steel-tooth motor of an electric vehicle is usually mounted on a wheel hub of the electric vehicle and is used for driving the wheel hub to rotate. The high-speed brushless steel-tooth motor comprises a stator assembly, a rotor assembly, a clutch device, a gear speed reduction unit, a fixed shaft for connecting a frame of the electric vehicle, a casing for fixedly connecting the wheel hub of the electric vehicle, and end caps connected on two ends of the casing. The stator assembly, the rotor assembly, the clutch device and the gear speed reduction mechanism are all positioned in an inner cavity enclosed by the casing and the end caps. A plurality of magnet devices which are used for absorbing iron scraps generated during mutual engagement transmission between a sun gear and planet gears and between the sun gear and internal gears in the gear speed reduction mechanism are detachably connected on the casing. The high-speed brushless steel-tooth motor of the electric vehicle helps a user to clean the iron scraps generated during mutual engagement transmission of the sun gear and the planet gears and between the sun gear and the internal gears in the gear speed reduction mechanism.

The utility model content:
The technical problems to be solved in the utility model is, a kind of electric motor car high-speed brushless steel-tooth motor of the iron foam that produces when being convenient to clear up sun gear and planetary gear and planetary gear and the intermeshing transmission of internal gear in gear reduction is provided.
technical solution of the present utility model is, provide a kind of electric motor car high-speed brushless steel-tooth motor with following structure: comprise stator module, rotor assembly, clutch apparatus, gear reduction, for the fixed axis that is connected with electromobile frame, be used for the casing that is fixedly connected with electric vehicle hub and the end cap that is connected to the casing two ends, stator module, rotor assembly, clutch apparatus and gear reduction all are arranged in the inner chamber that casing and end cap surround, wherein, removably be connected with the suction iron device of a plurality of iron foams that produce during for absorption gear reduction sun gear and planetary gear and planetary gear and the intermeshing transmission of internal gear on casing.
Electric motor car high-speed brushless steel-tooth motor described in the utility model, wherein, the suction iron device that removably is connected with a plurality of iron foams that produce during for absorption gear reduction sun gear and planetary gear and planetary gear and the intermeshing transmission of internal gear on casing refers to, have a plurality of radially tapped through holes that communicate with inner chamber on casing, each screw that radially all has been threaded in tapped through hole, the screw afterbody is connected with magnet, is provided with sealing ring between screw and casing.
after adopting above structure, compared with prior art, the utility model electric motor car high-speed brushless steel-tooth motor has the following advantages: in the utility model electric motor car high-speed brushless steel-tooth machine operation process, the iron foam that produces during intermeshing transmission between sun gear in gear reduction and planetary gear and planetary gear and internal gear can be inhaled the iron device to adsorbing, when needs cleaning iron foam, directly will inhale the iron device to disassembling, the iron foam just can be taken out of inner chamber, it is very simple and convenient that the suction iron device of dismounting small volume is dismantled the end cap at casing two ends relatively, greatly facilitate the cleaning work of iron foam.
Backing out screw by conventional spanner can clear up the iron foam, uses spanner that screw is resetted after cleaning, and whole process need not the specialized maintenance personnel, ordinary consumer just can operate, cleaning iron foam is very simple and convenient, and in addition, the sealing ring that is provided with between screw and casing mainly plays sealing function.
Description of drawings:
