Anti-lock brake apparatus, vehicle, electric vehicle and electric-assisted vehicle

An anti-lock brake apparatus, applied to a brake system, the brake system being used to provide a brake frictional force for a wheel, the brake system comprising a brake oil pipeline, and the anti-lock brake apparatus comprises:

• a volume-adjusting part, wherein the volume-adjusting part has a volume chamber, the volume chamber is connected into the brake oil pipeline, a volume of the volume chamber is continuously adjustable, the volume-adjusting part adjusts the volume of the volume chamber according to a state parameter of the wheel, to enable an oil pressure in the brake oil pipeline to vary, and the brake frictional force exerted on the wheel by the brake system to be adjustable;
• wherein the volume-adjusting part comprises:
• a volume-adjusting shell, which surrounds to form an inner chamber, and is provided with a first through hole and a second through hole at an interval;
• an adjusting member, which is slidably provided in the inner chamber, and divides the inner chamber into at least two independent chambers, wherein one chamber is the volume chamber and is between the adjusting member and the first through hole of the volume-adjusting shell, both the first through hole and the second through hole of the volume-adjusting shell are communicated with the volume chamber, the volume chamber is connected into the brake oil pipeline through the first through hole and the second through hole;
• and
• an adjusting unit, which is connected to the adjusting member, and is configured to adjust a position of the adjusting member according to the state parameter of the wheel, and thus to adjust a volume of the volume chamber connected into the brake oil pipeline.
