Automobile antiskid device

The invention discloses an automobile antiskid device. The antiskid device comprises anti-skid plates, a transmission mechanism and a driving device, wherein the anti-skid plates are symmetrically arranged. One end of each antiskid plate is connected with an automobile chassis/an automobile cross beam in a rotatable mode through a hinge pin. The other end of each antiskid plate is connected with the driving device through the transmission mechanism. Teeth are fixed to the bottom surface of each antiskid plate. The automobile antiskid device has the advantages that it is guaranteed that an automobile safely runs on a wet slippery road or an icy and snowy road, and meanwhile, under the condition that an existing brake system of the running automobile breaks down and is ineffective or the running automobile breaks down due to misuse, the emergency braking function can be achieved; the structure is simple, and an existing automobile structure is not changed; during operation, extra friction force is generated bet
