The invention relates to the technical field of electric bicycles and discloses an electric bicycle stall automatic braking hub. The braking hub comprises a bearing disc, wherein a connecting rod is welded to an outer side of the bearing disc, a brake disc is welded to an end, away from the bearing disc, of the connecting rod, and a trigger mechanism is arranged in the bearing disc; a front face of the bearing disc is rotationally connected with a mounting disc, and a brake mechanism is arranged on a front face of the mounting disc. According to the trigger mechanism and the stall automatic brake hub for the electric bicycle, through cooperative use of the trigger mechanism and the brake mechanism, when the running speed of the electric bicycle is too high and exceeds a safety range, a contact will make contact with a wire under the action of centrifugal force, a screw rotates, and in other words, a sliding sleeve rotates under the rotation of the screw; a brake pad is pushed in the direction close to the brake disc till the brake pad makes contact with the brake disc, the vehicle speed is reduced to be within the safety range, potential safety hazards are greatly reduced, and personal safety of a driver is guaranteed.
本发明涉及电动自行车技术领域,且公开了一种电动自行车用失速自动制动轮毂,包括轴承盘,所述轴承盘的外侧焊接有连接杆,所述连接杆远离轴承盘的一端焊接有制动盘,所述轴承盘的内部设置有触发机构,所述轴承盘的正面转动连接有安装盘,所述安装盘的正面设置有制动机构;所述触发机构,该电动自行车用失速自动制动轮毂,通过触发机构和制动机构的配合使用,当电动自行车行驶速度过快,超过安全范围外时,触点会在离心力的作用下与导线接触,知识螺杆转动,即滑套在螺杆的转动下,将制动片向靠近制动盘的方向推动,直至制动片与制动盘接触,使得车速降低至安全范围内,极大的降低了安全隐患,且保证了驾驶员的人身安全。
