The invention relates to an auxiliary braking device, and belongs to the technical field of vehicle braking. The auxiliary braking device comprises a fixed bottom plate, a lifting plate and a hydraulic cylinder, wherein the fixed bottom plate is fixedly arranged at the bottom of a vehicle; one end of the lifting plate is hinged to the fixed bottom plate, and braking friction blocks are arranged at the other end of the lifting plate; one end of the hydraulic cylinder is hinged to the bottom of the vehicle, and the other end of the hydraulic cylinder is hinged to the lifting plate. When urgent braking is performed under an accidental road condition, a hydraulic cylinder switch is triggered, so that the braking friction blocks rub against the ground to supply extra frictional force. The auxiliary braking device has the benefits that extra frictional force is supplied, so that the braking distance of the vehicle is shortened.
