Abstract
An electric hub for an electric scooter or an electric bicycle. Mainly comprises a motor shell and a width plate 2 of a left end cover 1, which are cast into a whole in a pressure equalizing way. The magnetic steel 3 is directly pasted on the inner cavity wall of the shell, and an inner stator 4 embedded with a winding and a right end cover 5 are respectively arranged in the shell. The utility model discloses combine driving motor and wheel hub into an organic whole to the structural rigidity and the operation precision of wheel have been improved.
Description
The utility model relates to the electric wheel hub of a kind of Electric Scooter or electric bicycle, belongs to the drive unit of vehicle.
Existing Electric Scooter or electric bicycle adopt direct drive mode more, be that drive motors is directly installed on the vehicle hub, form electronic hub, this structure has not only increased the weight of hub, and the processability of product structure of wheel hub overcoat is relatively poor, two kinds of structures of general at present employing: a kind of is to forge the cost height.Another kind is used thick-walled seamless steel pipes, and waste of material is bigger, and cost is also higher, and because of wheel hub overcoat and motor suit, when not only having increased the assembler, and has increased the cooperation link, thereby increased rigging error, influences the vehicle operation precision.
The purpose of this utility model provides the drive unit of a kind of rational Electric Scooter or electric bicycle.
The electric wheel hub that the utility model provides comprises that motor case and left end cap aluminium alloy compression casting are one, and casing is cast with some formers outward to replace width of cloth bar, some blocks of magnet steel is directly sticked on the internal chamber wall of casing, thereby has formed the external rotor of motor.And the internal stator that will be embedded with winding packs in the casing, and right end cap is packed on the right seam face of casing, it is characterized in that the wheel hub of drive motors and scooter or bicycle is combined together.
The utility model has improved the processability of product structure of Electric Scooter or wheel hub of electric bicycle part, reduced part in addition, thereby reduced cost, secondly, because motor and wheel hub combine together, improved the structural rigidity and the assembly precision of drive hub, this is vital to moving vehicle, structure of the present utility model can save general Electric Scooter or electric bicycle is worn width of cloth bar, and the man-hour of whole dragon is when having reduced the assembler of car load.
Fig. 1 is the sectional side elevation of the utility model electric wheel hub structure.
Below in conjunction with drawings and Examples the utility model is further described: motor case (1) and left end cap are die cast as one, casing is cast with some formers (2) outward to replace original width of cloth bar, magnet steel (3) is directly sticked on the inwall of casing, formed the external rotor of motor.At the indoor bearing of packing into of left bearing, the internal stator (4) that will be embedded with winding is again packed in the casing, the bearing of in the bearing chamber of right end cap (5), packing into earlier, then right end cap gently is pressed on the right seam face of casing, use again screw fastening it, promptly formed one and melted wheel hub and motor is the electric wheel hub of one.
Claims (2)
1, a kind of electric wheel hub comprises motor case and left end cap (1), former (2), magnet steel (3), the internal stator (4) that is embedded with winding and right end cap (5), it is characterized in that the wheel hub of drive motors and scooter or bicycle is combined together.
2, by the described electric wheel hub of claim 1, it is characterized in that former, wheel hub, the casing of drive motors, the left end cap of scooter or bicycle is integral with aluminium alloy compression casting.
