A cam self-adaptive automatic speed shift hub comprises a left hub frame (), a right hub frame (), a case body (), a power input device, a drive shaft (), a wheel () and a brake device (). The hub further includes a low-gear drive shaft (), a low-gear transmission mechanism positioned on the low-gear drive shaft (), and a cone-disc clutch cam self-adaptive speed shift assembly positioned on the drive shaft (), in which the low-gear drive shaft () positioned in the case body () is in rotation fit with the case body () and in parallel with the drive shaft (). Such a cam self-adaptive automatic speed shift hub can allow the motor/engine output power and vehicle running condition always in an optimal matching state, to achieve balance control between the vehicle driving torque and the comprehensive driving resistance.
