Between the disc bottom plates 21;

内盘8的结构是在内盘底板82上成型有内盘外挡圈81和内盘内挡圈83，轴承11的外圈固定在内盘内挡圈83上，轴承11的内圈固定在轴套13上，轴套13固定在电动自行车轮毂1的转轴14上；The inner disk 8 has a structure in which an inner disk outer ring 81 and an inner disk inner ring 83 are formed on the inner disk bottom plate 82. The outer ring of the bearing 11 is fixed to the inner disk inner ring 83, and the inner ring of the bearing 11 is fixed on the sleeve 13. The sleeve 13 is fixed on the rotating shaft 14 of the electric bicycle hub 1;

电磁线圈10插套在内盘外挡圈81和内盘内挡圈83之间，安装盘插柱23插套在摩擦片12上的预设通孔中，电磁线圈10与摩擦片12相对，电磁抱刹9抱紧在内盘8上，涡流簧片15置于外盘3和内盘8之间，涡流簧片15上端固定在外盘3上，涡流簧片15的下端固定在内盘8上。The electromagnetic coil 10 is inserted between the outer disc outer ring 81 and the inner disc inner ring 83, and the mounting disc insertion post 23 is inserted into the predetermined through hole on the friction plate 12, and the electromagnetic coil 10 is opposite to the friction plate 12, and the electromagnetic coil is The brake 9 is hung on the inner disc 8, and the vortex reed 15 is placed between the outer disc 3 and the inner disc 8.

工作原理：见图1所示，电动自行车轮毂1转动时，拉线抱刹4和电磁抱刹9是松开的，电磁线圈10没有通电，这样内盘8和摩擦片12分离，涡流簧片15处于自然状态。Working principle: As shown in Fig. 1, when the electric bicycle hub 1 rotates, the wire holding brake 4 and the electromagnetic holding brake 9 are loosened, and the electromagnetic coil 10 is not energized, so that the inner disk 8 and the friction plate 12 are separated, and the eddy current spring 15 is at Natural state.

当电动自行车刹车时，拉线抱刹4抱紧外盘3，外盘3停止转动，电磁线圈10通电，将内盘8和摩擦片12吸合在一起，内盘8随电动自行车轮毂1转动，内盘8转动时涡流簧片15被卷紧而储存机械能， 这个过程大致3至5秒，然后，电磁抱刹9抱紧内盘8。When the electric bicycle brakes, the cable holding brake 4 holds the outer disk 3, the outer disk 3 stops rotating, the electromagnetic coil 10 is energized, the inner disk 8 and the friction plate 12 are sucked together, and the inner disk 8 rotates with the electric bicycle hub 1, and the inner disk 8 rotates. The eddy current spring 15 is wound up to store mechanical energy, This process is roughly 3 to 5 seconds, and then the electromagnetic brake 9 holds the inner disk 8.

再次启动电动自行车时，电磁抱刹9抱紧内盘8，内盘8和摩擦片12分离，涡流簧片15的张力作用于外盘3，此时，棘爪5与棘齿22相啮合，涡流簧片15的力通过安装盘2作用于电动自行车轮毂1，这一过程大致2秒左右，这样刹车时产生的多余能量便经过涡流簧片15储存达到了再次利用转化。在城市道路间行走的电动自行车，由于刹车频繁，所以可以节省出大量的刹车所致的能量，从而让电动自行车的一次充电后，能使用更久，从而达到增程的效果。When the electric bicycle is started again, the electromagnetic brake brake 9 holds the inner disk 8, and the inner disk 8 and the friction plate 12 are separated, and the tension of the eddy current spring 15 acts on the outer disk 3. At this time, the pawl 5 meshes with the ratchet 22, and the eddy current reed The force of 15 acts on the electric bicycle hub 1 through the mounting plate 2, which is about 2 seconds, so that the excess energy generated during braking is stored by the eddy current reed 15 to achieve reuse conversion. Electric bicycles that travel between urban roads can save a lot of energy from the brakes because of the frequent braking, so that the electric bicycle can be used for a longer period after one charge, thereby achieving the effect of the extended range.

电动自行车倒车时，拉线抱刹4、电磁抱刹9和电磁线圈10均处于松开状态，不影响电动自行车的正常倒车。When the electric bicycle is reversing, the cable holding brake 4, the electromagnetic holding brake 9 and the electromagnetic coil 10 are all released, and the normal reverse of the electric bicycle is not affected.

在具体操作时，见图6所示，拉动手刹17，拉线18拉动拉线抱刹4抱紧外盘3，同时手刹17触碰电磁开关19，电磁开关19为控制芯片的按键电路，由控制芯片去控制电磁抱刹9和电磁线圈10工作；同时现有电动自行车轮毂1的轮毂刹车20仍然保留，本发明只是在现有电动自行车轮毂1上加装，而现有电动自行车原来的结构不动。 In the specific operation, as shown in Fig. 6, pull the handbrake 17, pull the wire 18 to pull the wire holding brake 4 to hold the outer disk 3, while the hand brake 17 touches the electromagnetic switch 19, the electromagnetic switch 19 is the button circuit of the control chip, and the control chip goes The electromagnetic brake brake 9 and the electromagnetic coil 10 are controlled to operate; at the same time, the hub brake 20 of the existing electric bicycle hub 1 is still retained, and the present invention is only installed on the existing electric bicycle hub 1, and the original structure of the existing electric bicycle is not moved.
