Abstract
The utility model provides a wheel of an electric motorcycle, which comprises a wheel body, a rotor, a stator, an end cover, a hub cap and a rear hub brake. The stator penetrates through the end cover, a bearing is arranged between the stator and the end cover, and a sealing ring is further disposed between the end cover and the stator. The sealing ring is disposed between the end cover and the stator, accordingly, an unnecessary gap between the end cover and the stator can be avoided, in other words, impurities, water and the like are prevented from seeping into a space with precise components of a motor, the possibility of fault of a circuit of the motor is greatly reduced, and braking safety is improved.
Description
Technical field
The utility model relates to a kind of battery-operated motor cycle wheel, relates in particular to the hermetically-sealed construction of battery-operated motor cycle wheel.
Background technology
Battery-operated motor cycle has received consumers in general's welcome with its light, pollution-free, as to be easy to learn and use characteristics, has obtained extensively popularizing, and as the importance of its safety, its braking quality enjoys attention.At present, have much room for improvement, be prone to cause foreign matter, moisture to infiltrate inside wheel and cause rotor fault, thereby influence the brake safety of battery-operated motor cycle at the end cap of battery-operated motor cycle wheel and the sealing effectiveness between the stator.
Summary of the invention
The purpose of the utility model is to provide a kind of battery-operated motor cycle wheel, to solve sealing effectiveness defective that prior art exists and the problem that possibly cause the brake fault thereof.
To achieve these goals; The battery-operated motor cycle wheel that the utility model provides comprises wheel, rotor, stator, end cap, hub cap, afterwards hub is stopped, and said stator passes said end cap, and is provided with bearing between said stator and the end cap; Wherein, also be provided with seal ring between said end cap and the stator.
According to a kind of preferred implementation of above-mentioned battery-operated motor cycle wheel, wherein, said seal ring is located at the said bearing outside.
According to a kind of preferred implementation of above-mentioned battery-operated motor cycle wheel, wherein, said seal ring is lip-type packing.
Through between end cap and stator, seal ring being set; Can avoid producing between the two unnecessary slit; Also promptly avoid impurity, moisture etc. to infiltrate the residing space of precise part of motor, greatly reduce the possibility of the circuit et out of order of motor, improved the brake safety.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
Fig. 1 schematically shows the structure of the utility model preferred embodiment, and shown in it, this preferred embodiment comprises that wheel 3, rotor 5, stator 9, end cap 4, hub cap 2, back hub stop 1, nut 8, anti-rotation locking plate 10, bearing 6.Hub cap 2 and back hub stop 1 be located at a side end cap 4 outer wall, stator 9 passes wheel 3 end covers at two sides 4, the two ends of stator 9 are equipped with nut 8, anti-rotation locking plate 10 etc.Be provided with bearing 6 between stator 9 and the end cap 4 and be beneficial to relatively rotate, in addition, also be provided with seal ring 7 between end cap 4 and the stator 9 to increase the leak tightness in space, rotor 5 place.
In this preferred embodiment, two seal rings 7 are located at two bearings 6 outsides respectively, and seal ring 7 is lip-type packing.
To sum up; Owing between end cap and stator, be embedded with seal ring, and lip-type packing also has self-tightening, so can avoid infiltrations such as impurity, moisture basically between end cap and the stator; Guaranteed the cleaning in space, rotor place; It is thus clear that the utility model can reduce frequency of maintenance and cost greatly, increases the service life.
Can know that by technological general knowledge the utility model can be realized through other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all is a casehistory, is not only.All in the utility model scope or the change that is being equal in the scope of the utility model all comprised by the utility model.
