The invention relates to the technical field of rail transit, and discloses an active permanent magnet braking system for rail transit. The system comprises a guide rail, wherein the side wall of theupper side of the guide rail is fixedly connected with a pole shoe; a brake side plate is movably arranged outside the pole shoe in a sleeving manner; brake iron is fixedly connected to the side wallof the lower side of the brake side plate; a through groove is formed in the side wall of the upper side of the pole shoe; a permanent magnet is embedded in the upper side of the brake side plate; a driver is fixedly connected to the side wall of the upper side of the brake side plate and is electrically connected with the permanent magnet; a U-shaped plate is fixedly connected to the side wall ofthe upper side of the brake side plate; two fixing cylinders are symmetrically and fixedly connected to the side wall of the upper side of the U-shaped plate; and moving rods are movably connected into the two fixing cylinders in a sleeved mode. The problem that cracks occur in the brake system when the brake system deforms is solved, the stability of the brake system when the temperature changesis effectively improved, the abrasion speed of the brake side plate is effectively reduced, and the service life of the brake side plate is prolonged.
本发明涉及轨道交通技术领域,且公开了轨道交通用主动式永磁制动系统,包括导轨,所述导轨上侧的侧壁固定连接有极靴,所述极靴外活动套设有制动侧板,所述制动侧板下侧的侧壁固定连接有制动铁,所述极靴上侧的侧壁开设有通槽,所述制动侧板上侧的内部嵌设有永磁铁,所述制动侧板上侧的侧壁固定连接有驱动器,所述驱动器与永磁铁电连接,所述制动侧板上侧的侧壁固定连接有U型板,所述U型板上侧的侧壁对称固定连接有两个固定筒,两个所述固定筒内均活动套接有移动杆。本发明避免了制动系统变形时内部出现裂痕的问题,有效的提高了制动系统在温度变化时的稳定性,有效的降低了制动侧板的磨损速度,提高了制动侧板的使用寿命。
