Abstract
The utility model discloses a base mounting structure of a same hub motor shell for adapting to flywheels of different tower bases, which comprises a hub body, a flywheel base and bolts, wherein a first flange plate is arranged at the top of the hub body and is provided with a middle through hole and first through holes arranged in an annular array, an annular clamping groove is formed in the flywheel base, a sealing ring is sleeved in the annular clamping groove, and the outer wall of the sealing ring is attached to the hub body. The hub body and the flywheel base are integrally divided into two parts, one is the hub body and the other is the flywheel base, and the hub body and the flywheel base are locked by screws after flange positioning, so that when different types of flywheel bases are needed, only different flywheel base bodies are needed to be replaced, and the hub body does not need different processing dies, so that the die sinking production cost can be reduced.
Description
Technical Field
The utility model belongs to the technical field of hub motors, and particularly relates to a base mounting structure of a same hub motor shell for adapting to flywheels of different tower bases.
Background
The existing hub motor is used for meeting the requirements that different single-speed, multi-speed and tower-base flywheels are required to be provided with different hub dies to adapt to different flywheels, different flywheels are required to be provided with different shells to adapt to different flywheels, and the existing flywheel base and the shells are integrated. In order to adapt to different forms of flywheel, the shell needs to be processed with different dies, the die cost is high, the shell of the product cannot be used universally, and the shell is various in type and size.
Disclosure of Invention
The technical problems to be solved by the utility model are as follows: the universal hub motor shell can adapt to the installation requirements of different types of flywheel bases.
In order to solve the technical problems, the utility model is realized by the following technical scheme: the utility model provides a base mounting structure of same in-wheel motor shell adaptation different tower base flywheels, includes wheel hub body, flywheel base and bolt, wheel hub body top has first ring flange, first ring flange has middle part through-hole and is the first through-hole that annular array set up, the flywheel base lower part has the second ring flange, with first through-hole matched with second screw hole on the second ring flange, flywheel base slidable mounting is in wheel hub body's middle part through-hole, second ring flange passes through bolt locking fixed connection with first ring flange, be provided with annular draw-in groove on the flywheel base, the sealing washer is installed in annular draw-in groove endotheca, the outer wall laminating of sealing washer is on wheel hub body.
Preferably, the lower port of the first flange plate is provided with an oblique angle structure.
Preferably, the tops of the first through hole and the second threaded hole are both provided with a frustum-shaped countersunk hole structure.
Preferably, the bolt head is arranged in a frustum-shaped structure matched with the second threaded hole.
Compared with the prior art, the utility model has the following advantages: the hub body and the flywheel base are integrally divided into two parts, one is the hub body and the other is the flywheel base, and the hub body and the flywheel base are locked by screws after flange positioning, so that when different types of flywheel bases are needed, only different flywheel base bodies are needed to be replaced, and the hub body does not need different processing dies, so that the die sinking production cost can be reduced.

Detailed Description
The utility model is described in detail below in connection with specific embodiments:
the utility model provides a same in-wheel motor shell adaptation different tower base flywheel's base mounting structure as shown in fig. 1 through 4, includes wheel hub body 1, flywheel base 2 and bolt 3, wheel hub body 1 top has first ring flange 13, first ring flange 13 has middle part through-hole 11 and is the first through-hole 12 that the annular array set up, flywheel base 2 lower part has second ring flange 21, with first through-hole 12 matched with second screw hole 22 on the second ring flange 21, flywheel base 2 slidable mounting is in wheel hub body 1's middle part through-hole 11, second ring flange 21 passes through bolt 3 locking fixed connection with first ring flange 13, be provided with annular draw-in groove 23 on the flywheel base 2, annular draw-in groove 23 internal joint installs the sealing washer, the outer wall laminating of sealing washer is on wheel hub body 1, and the sealing washer can increase the leakproofness between flywheel base 2 and the wheel hub body 1.
In practical installation, the second flange 21 is conveniently embedded and installed in the hub body 1, and the lower port of the first flange 13 is provided with a bevel structure 14.
For the installation location is carried out with first through-hole 12 to the bolt 3 lower extreme of being convenient for, first through-hole 12, second screw hole 22 top all set up to frustum form countersunk head structure, bolt 3 head sets up to with second screw hole 22 matched with frustum form structure, and second screw hole 22 and bolt 3 cooperation setting can guarantee hub body 1 surface's planarization, avoid taking place the interference with other parts.
