Abstract
The utility model discloses a solid tire hub motor, which comprises a hub main body, a solid tire and an end cover arranged on one side of the hub main body, wherein the outer circumference of the hub main body is provided with a rim, the bottom of the rim is provided with a groove surrounding the rim, and the inner wall of the solid tire is integrally formed with a convex annular body matched with the groove; the method is characterized in that: the utility model discloses a solid tyre's positioning structure, including rim, annular body, solid tyre, locating groove, solid tyre's recess bottom is even is provided with a plurality of constant head tank, solid tyre's ring body inner wall integrated into one piece has the location lug of a plurality of and constant head tank adaptation, solid tyre installs on the rim, and the location lug imbeds in the constant head tank. The utility model discloses a location lug is connected with the cooperation location of constant head tank for solid tyre and rim cooperation are inseparable, avoid solid tyre to produce the displacement with the rim when the motion, avoid solid tyre and rim because the displacement rubs mutually and produces wearing and tearing and generate heat, have improved solid tyre's life, have guaranteed the stability and the safety of operation.
Description
Technical Field
The utility model belongs to the technical field of electric scooter in-wheel motor, especially, relate to a solid tyre in-wheel motor.
Background
The hub motor is characterized in that a power device, a transmission device and a braking device are integrated into the hub, so that the mechanical part of the electric vehicle is greatly simplified. The hub motor is widely applied to the fields of electric vehicles and electric scooters.
Most electric scooter's exempts from pneumatic tire at present all is divided, the rim separation mode of tire and wheel hub promptly, and the tire closely overlaps on the rim, but after the tire used for a period of time, the cooperation of tire and rim can produce not hard up problem, because the frictional resistance on tire and ground, tire and rim can produce the phenomenon of displacement when high-speed operation, threatens to the safety constitution.
In patent No. 201620437496.3, a sleeve and a bolt with internal threads are embedded in the solid tyre body and integrally formed with the solid tyre, a mounting hole is arranged on the wheel hub, and the bolt is inserted in the mounting hole and fastened in the sleeve, so that the tyre body and the wheel hub are tightly sleeved together, and the tyre body cannot displace with the wheel hub when moving. However, the hub motor of the electric scooter is small in size, the diameter of the hub motor is generally between 10cm and 20cm, and the hub and the rim are tightly connected or integrally formed, so that the hub is not provided with a mounting hole and a space for inserting a bolt, and the tire and the rim (hub) cannot be prevented from being displaced by the method.
Disclosure of Invention
The utility model aims at providing a solid tyre in-wheel motor to the not enough of above-mentioned prior art existence.
The utility model adopts the technical proposal that: a solid tire hub motor comprises a hub main body, a solid tire and an end cover arranged on one side of the hub main body, wherein a rim is arranged on the outer circumference of the hub main body, a groove surrounding the rim is formed in the bottom of the rim, and a convex annular body matched with the groove is integrally formed on the inner wall of the solid tire; the utility model discloses a solid tyre's positioning structure, including rim, annular body, solid tyre, locating groove, solid tyre's recess bottom is even is provided with a plurality of constant head tank, solid tyre's ring body inner wall integrated into one piece has the location lug of a plurality of and constant head tank adaptation, solid tyre installs on the rim, and the location lug imbeds in the constant head tank.
The side of the solid tyre is provided with a hole.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses a location lug is connected with the cooperation location of constant head tank for solid tyre and rim cooperation are inseparable, avoid solid tyre to produce the displacement with the rim when the motion, avoid solid tyre and rim because the displacement rubs mutually and produces wearing and tearing and generate heat, have improved solid tyre's life, have guaranteed the stability and the safety of operation.

Fig. 3 is a cross-sectional view a-a of fig. 1 (solid tire and hub body).
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-3: a solid tire 1 hub motor comprises a stator assembly, a rotor assembly and a solid tire 1, wherein the rotor assembly comprises a hub main body 2, magnetic steel arranged on the inner wall of the hub main body 2, an end cover 3 arranged on one side of the hub main body 2 and the like, the stator assembly comprises a motor shaft 4, an iron core 5 is arranged on the motor shaft 4, an enameled wire winding 6 is arranged on the iron core 5, shaft holes and bearings 7 opposite to the shaft holes are respectively arranged on the end cover 3 and the hub main body 2, the motor shaft 4 is arranged in the bearings 7 of the end cover 3 and the hub main body 2, and two ends of the motor shaft 4 penetrate out of the shaft holes; the outer circumference of the hub main body 2 is integrally formed with a rim 8, the bottom of the rim 8 is provided with a groove 9 surrounding the rim 8, and the inner wall of the solid tire 1 is integrally formed with a convex annular body 10 adapted to the groove 9.
The bottom of the groove 9 of the rim 8 is uniformly provided with a plurality of positioning grooves 11, the number of the positioning grooves 11 is 4-8, a plurality of positioning convex blocks 12 matched with the positioning grooves 11 are integrally formed on the inner wall of the annular body 10 of the solid tyre 1, the solid tyre 1 is installed on the rim 8, and the positioning convex blocks 12 are embedded into the positioning grooves 11. The positioning bump 12 and the positioning groove 11 are matched and positioned to be connected, so that the solid tire 1 and the rim 8 are matched tightly, the solid tire 1 is prevented from displacing with the rim 8 during movement, the solid tire 1 and the rim 8 are prevented from being worn and heated due to mutual friction of displacement, the service life of the solid tire 1 is prolonged, and the stability and the safety of operation are ensured.
The side surface of the solid tyre 1 is provided with the hole 13, so that the weight of the solid tyre 1 can be reduced.
