Coaxial type electric hydraulic disc brake

The utility model discloses a coaxial type electric hydraulic disc brake which is composed of three components: an electric hydraulic pushing device, lever force amplifiers and a friction brake component. Each lever force amplifier is composed of the following components: a cylindrical pin, a sliding millstone, a compression spring, a pull rod screw and a lever. An external surface of a transition end cap is provided with three hinged double-ear bases. The middle part of each force amplifying lever is respectively hinged with the middle part of each base ear. A long arm end of each force amplifying lever clings to an outer end face of a piston, and the other end clings to the pull rod screw. The cylindrical pin restrains the displacement of the lever in two directions. The lever can only swing around the cylindrical pin. One end of each pull rod screw is respectively fixed into three uniformly arranged mounting holes of the sliding millstones. The coaxial type electric hydraulic disc brake is a novel structur
