The invention relates to the technical field of drum brakes, and provides a drum type parking braking device supporting active clearance adjustment and a control method thereof.The drum type parking braking device supporting active clearance adjustment comprises brake shoes, a brake cylinder, a driving mechanism and a controller, the brake cylinder is arranged between the pair of brake shoes, and the driving mechanism is arranged between the brake shoes; the brake cylinder comprises a shell and a pushing assembly, the pushing assembly is movably arranged in the shell in the axial direction, the pushing assembly comprises a first driving end and a second driving end, the first driving end acts on one brake shoe, and the second driving end acts on the other brake shoe; the driving mechanism acts on the pushing assembly and is used for driving the first driving end and the second driving end to synchronously move so as to drive the pair of brake shoes to be close to or far away from each other and positioning the first driving end and the second driving end at any position after movement; the controller is electrically connected with the driving mechanism and used for controlling starting and stopping of the driving mechanism. The brake system is simple in structure, and the stability and reliability of the brake system are improved.

    本发明涉及鼓式制动器技术领域,提供一种支持间隙主动调节的鼓式驻车制动装置及其控制方法,支持间隙主动调节的鼓式驻车制动装置包括:制动蹄片、制动分泵、驱动机构和控制器,制动分泵设置在一对制动蹄片之间,制动分泵包括壳体和推动组件,推动组件沿轴向可移动地设置在壳体中,推动组件包括第一驱动端和第二驱动端,第一驱动端作用于其中一个制动蹄片,第二驱动端作用于另一个制动蹄片;驱动机构作用于推动组件,用于驱使第一驱动端和第二驱动端同步移动,以驱动一对制动蹄片相互靠近或远离,并用于将第一驱动端和第二驱动端定位在移动后的任一位置;控制器与驱动机构电连接,用于控制驱动机构的启停;本发明结构简单,提高了制动系统的稳定性和可靠性。
