<p>A grade-capable emergency brake system, comprising a starting device, a drive assembly, and a brake assembly; the brake assembly comprises a connecting rod (31), and a fan-shaped brake (32); the front end of the fan-shaped brake (32) is provided with a brake wedge (33); the arc-shaped bottom edge of the fan-shaped brake (32) is provided with evenly-distributed braking claws (34); the brake assembly comprises two sets of a forward brake assembly (8), and at least one set of a back brake assembly (9); the forward brake assemblies (8) are basically structurally consistent with the back brake assemblies, the only difference being that the connecting rods of the forward brake assemblies (8) are longer than those of the back brake assemblies (9); via the drive assembly, the starting device causes the two forward fan-shaped brakes (32) to flexibly contact the ground and raise the front part of the automobile, so that the two front wheels of the automobile are lifted off the ground; when the maximum allowed height is reached, the fan-shaped brake (32) located below the chassis at the rear of the automobile contacts the ground and raises the rear of the automobile, so that the two rear wheels of the automobile are lifted off the ground; with that, the great inertial force of the automobile is completely and softly absorbed by at least three fan-shaped friction devices, thus stopping the automobile.</p> |
