Detailed ways

In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

As shown in Figure 1, the rotation mode of the outer flywheel 4 (that is, the flywheel is installed forwardly) is: according to the working principle of the ratchet pawl, when the outer ring of the outer flywheel 2 is the active part and rotates clockwise, it will drive the inner ring of the outer flywheel 3 revolutions, when the outer ring 2 of the outer flywheel is the active part, the inner ring 3 of the outer flywheel can rotate freely; when the inner ring 3 of the outer flywheel is the active part, the outer ring 2 of the outer flywheel can rotate freely When the outer flywheel inner ring 3 is the driving part and rotates counterclockwise, it will drive the outer flywheel outer ring for 2 turns.

As shown in Figure 2, the rotation mode of the first/second inner flywheel (that is, the reverse installation of the flywheel) is as follows: according to the working principle of the ratchet pawl, when the outer ring 14 of the first/second inner flywheel is the active part, it rotates clockwise When rotating, the first/second inner flywheel inner ring 15 can turn freely, and when the first/second inner flywheel outer ring 14 is the active part, it will drive the first/second inner flywheel inner ring for 15 turns when it rotates counterclockwise; The inner ring 15 of the first/second inner flywheel will drive the outer ring 14 of the first/second inner flywheel when the active part rotates clockwise, and rotate counterclockwise when the inner ring 15 of the first/second inner flywheel is the active part When the first/second inner flywheel outer ring 14 will turn arbitrarily.

As shown in Figure 3, a hub motor clutch for an electric vehicle comprises a hub motor 9, a first inner flywheel 8 and a second inner flywheel 5 are respectively fixed on both sides of the hub motor 9, and the first inner flywheel 8 A left fixed ring 7 is installed on the outside of the left fixed ring 7, and a left protective shell 6 is installed on the outside of the left fixed ring 7, a right fixed ring 11 is installed on the outside of the second inner flywheel 5, and a The right protective shell 10, the outer flywheel 4 is installed on the outside of the right protective shell 10, the outer ring of the outer flywheel 2 is provided with a chain, the first inner flywheel 8 and the second inner flywheel 5 are installed in reverse, The outer flywheel 4 is installed forward;

The rotating shaft 12 of the in-wheel motor 9 is fixedly connected with the inner ring of the first inner flywheel and the inner ring of the second inner flywheel respectively, and the outer ring of the first inner flywheel is fixedly connected with the left fixed ring 7, and the left fixed ring 7 is fixedly connected by a pin 13 is fixedly connected with the left protective shell 6, the outer ring of the second inner flywheel is fixedly connected with the right fixed ring 11, and the right fixed ring 11 is fixedly connected with the right protective shell 10 through pins 13, and the right protective shell 10 is connected with the outer Flywheel inner ring 3 is fixedly connected. Spokes are installed on the right shell 10 . Spokes are installed on the left protective shell 6 .

When the power is turned on, the rotating shaft 12 of the hub motor 9 rotates clockwise, because the first inner flywheel 8 fixed on the left casing 6 is reversely installed, and the second inner flywheel 5 fixed on the right casing 10 is It is installed in reverse (see Figure 2), so it will drive the outer ring of the first inner flywheel, the left casing 6, the outer ring of the second inner flywheel and the right casing 10 to rotate clockwise, thereby pushing the wheel to rotate clockwise.
