Description
Technical field
The utility model relates to hub motor for electric automobile.
Background technology
At present, along with this low-carbon (LC) of electric automobile, environmental protection, transport of going on a journey easily rises gradually, and new forms of energy car has become now automobile industry and had much prospective field.The Driving technique of new forms of energy car has no small difference with traditional combustion engine automobile, and wherein has a class Driving technique to have very large development prospect, wheel hub motor technology that Here it is.Wheel hub motor has compact conformation, and succinctly, the layout of drive efficiency is more flexible, does not need the features such as complicated machine driving.But due to wheel hub motor work under bad environment, so very high to the seal request of motor.Existing motor is to bearing and motor shaft link position and what adopt between lead-out wire and motor shaft is that sealing ring seals, and achieves good effect.But adopt sealant sealing between motor hub shell and motor housing more, there is very large leak in this sealing means, motor is easy to produce vibrations in motion process, the generation of motor seal glue can be made like this to loosen and cause the foreign material such as water to enter motor thus cause electric motor short circuit even to burn out.And motor go wrong after install and dismounting time also have very large inconvenience.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of hub motor for electric automobile mounting structure, prevent the impurity such as water in motor operation course from entering motor, ensure that motor motor in long-term motion process has fine sealing, improve the useful life of motor, solve the problem of motor in dismounting simultaneously.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of hub motor for electric automobile mounting structure, comprise motor hub shell, in the left and right sides of motor hub shell, sealing is fixed with motor housing, external rotor and internal stator is provided with in motor hub shell, described internal stator is installed on motor center axle, bearing is provided with between described motor center axle and motor housing, described external rotor is located at internal stator outer circumferential sides, two ends, the left and right outer circumference surface of described motor hub shell is provided with circular cone external screw thread, the port inner peripheral surface of described motor housing is provided with cylindrical internal thread, described motor hub shell forms thread seal by circular cone external screw thread with coordinating of cylindrical internal thread with between motor housing.
Preferably, the externally threaded tapering of described circular cone is 1:16.
Preferably, the externally threaded thread form angle angle of described circular cone is 55 degree.
Preferably, described external rotor and motor housing bolted are integrated.
The utility model structure is simple, thread seal is adopted between motor hub shell and motor housing, thread seal is a kind of airtight mechanical seal, not filled or sealing matter just can Leakage prevention, can prevent the impurity such as water in motor operation course from entering motor, and can ensure that motor motor in long-term motion process has fine sealing, improve the useful life of motor, and solve the problem of motor in dismounting.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the externally threaded schematic diagram of circular cone.
Embodiment
As shown in Figure 1, a kind of hub motor for electric automobile mounting structure, comprise motor hub shell 1, in the left and right sides of motor hub shell 1, sealing is fixed with motor housing 2, external rotor and internal stator 7 is provided with in motor hub shell 1, described internal stator is installed on motor center axle 4, bearing 3 is provided with between described motor center axle and motor housing, described external rotor is located at internal stator outer circumferential sides, two ends, the left and right outer circumference surface of described motor hub shell is provided with circular cone external screw thread 6, the port inner peripheral surface of described motor housing is provided with cylindrical internal thread 5, described motor hub shell forms thread seal by circular cone external screw thread with coordinating of cylindrical internal thread with between motor housing.Described external rotor and motor housing bolted are integrated.
As shown in Figure 2, the externally threaded tapering of described circular cone is 1:16.The externally threaded thread form angle angle of described circular cone is 55 degree.
What adopt between motor hub shell 1 motor housing 2 is thread seal.Circular cone external screw thread 6 above motor hub shell 1 has the tapering of a 1:16 when processing, and the screw thread on the motor housing 2 coordinated with it is cylindrical internal thread 5, such cylindrical internal thread 5 combines with circular cone external screw thread 6 will be more and more tighter, the angle of the thread form angle of circular cone external screw thread processing is 55 degree, thus defining thread seal, such motor just does not need to take auxiliary seal measure.Fastening good external rotor can be again fastening with bolt, although such motor produces vibration in motion process, greatly reduces the impact of this part sealing.And also achieve convenience in motor assembling and dismounting, motor housing is coordinated with motor center axle 4 by bearing 3, motor in manufacturing process can be press-fited by forcing press, but be just difficult to dismounting when dismantling, and do not having at ordinary times the damage also easily causing motor bearings is installed in forcing press situation.Had this hermetically-sealed construction, motor only needs to tighten motor housing 2 in installation process, and such motor steadily will assemble not damaging in bearing 3 situation, is also as a same reason when dismounting.
