Detailed Description
The present invention will be described with reference to the following embodiments and drawings, but the embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.
As shown in fig. 1, the present invention provides a hub for a hub motor, which is embodiment 1 and includes a hub 1 and a motor 2.
The hub 1 comprises a cylindrical rim 11, a wheel disk 12 is arranged between the outer ends of the rim 11, and a shaft hole 13 is arranged in the middle of the wheel disk 12. The distance (i.e. the offset, ET) between the inside of the web 12 and the centre line of the rim 11 is 0-80mm, preferably 50 mm. The offset distance of the spoke plate 12 is far larger than that of a common hub, and a larger installation space can be provided for installing a motor with larger power.
The rim 11 has an annular outer rim 14 at its outer end and an annular inner rim 15 at its inner end. The inner rim 15 is provided with a plurality of bolt seats 16 distributed along the periphery of the inner rim 15, the thickness of each bolt seat 16 is larger than that of the inner rim 15, and horizontal bolt holes are formed on the outer side of each bolt seat 16.
The motor 2 is located in the inner space of the rim 11, the housing of the motor 2 includes a cylindrical housing 21, a front cover plate 22 and a rear cover plate 23 are respectively fixed to two ends of the housing 21, the front cover plate 22 is connected to the web 12 through a first fixing bolt 24, the rear cover plate 23 is connected to the inner rim 15 through a second fixing bolt 25, the second fixing bolt 25 is located in the bolt hole of the corresponding bolt seat 16, and an output shaft 26 of the motor 2 is located in the shaft hole 13. In order to enhance the sealing effect, an annular concave surface 151 is arranged outside the inner rim 15 to form a step, and the back cover plate 23 is located in the concave surface 151, so that the back cover plate 23 of the motor 2 not only serves as an end cover of the hub motor, but also is fixed on the concave surface 151 of the inner rim 15 of the hub through the second fixing bolt 25 to play a role in sealing and supporting.
In this embodiment, the rear cover plate 23 is a flat plate, and the outer side surface is flush with the outer side of the inner rim 15. As shown in fig. 2, which is embodiment 2 of the present invention, the difference from embodiment 1 is that the middle portion of the back cover plate 23 is recessed toward the direction of the web 12. As shown in fig. 3, which is embodiment 3 of the present invention, the difference from embodiment 1 is that the middle portion of the back cover 23 is projected in a direction away from the web 12. The flat plate in the middle of the rear cover plate 23 protrudes outwards or inwards, so that the length of the motor 2 can be adjusted to adjust the power of the motor 2.
As shown in fig. 4, it is embodiment 4 of the present invention, which is different from embodiment 1 in that a wedge-shaped abutting ring 3 is provided in a gap between the housing 21 and the rim 11 to secure a supporting strength. The position of the back cover plate 23 corresponding to the wedge-shaped abutting ring 3 is provided with a reinforcing bolt 4 abutting against the wedge-shaped abutting ring 3, and the reinforcing bolt 4 is sleeved with a reinforcing nut 5.
According to the hub motor matched with the hub, under the condition of meeting the requirement of tire mounting, the diameter space of a rim is enlarged as much as possible (namely, the groove bottom is narrowed), and meanwhile, the offset distance (ET) is increased; in order to ensure the integral strength, the end surface (wheel rim) of the hub at the inlet side of the hub motor is thickened, and the connection with the end cover plate of the hub motor is increased, so that the space is increased, and the strength is ensured to adapt to the installation of a high-power hub motor.
The utility model is defined by the claims. Based on this, it should be understood that various obvious changes and modifications can be made by those skilled in the art, which are within the main spirit and scope of the present invention.
