Central parking battlepin brake

The invention discloses a central parking battlepin brake which comprises a left side braking unit and a right side braking unit arranged in bilateral symmetry; the structure of the left side brakingunit is the same as that of the right side braking unit; circular ring shells of the left side braking unit and the right side braking unit are fixedly connected to form a rigid body through a long bolt; and a plurality of brake discs with uniformly formed taper holes are mounted between the left side braking unit and the right side braking unit to form the central parking battlepin brake. Throughreasonable structure configuration, parking brake is arranged into brake of combination of a taper pin and a friction plate; an air chamber is formed in a circular ring; the original two friction plates are changed into a plurality of friction plates; increase of a friction surface is combined with rigid locking to realize reliable parking capacity so as to realize the purposes of saving the chassis arranging space, lower
