The invention discloses an electromagnetic eddy current braking device for high-speed vehicle braking, and belongs to the technical field of high-speed vehicle braking. The device is composed of an excitation unit, a shell device and a rotor device. According to the invention, the device is novel in structure and clear in working principle; the excitation unit is used for providing stable and reliable braking force, most of heat generated on a excitation winding is directly discharged through a water cooling system, and a small part of heat is discharged out of a brake through an air cooling system; an air channel opening is formed in the edge of the excitation unit, so that an air flow path is longest, and heat dissipation is sufficient; the shell is of a rotary structure, and a pluralityof heat dissipation ribs are additionally arranged on the shell to facilitate discharging of internal heat; The cooling fins of the rotor heat dissipation structure are integrated with the rotor, andeddy heat generated by the rotor heat dissipation structure is dissipated through rib plates; And the edges of the rib plates are designed to be of fan blade structures, the rotor cooling fins rotateduring braking, and the fan blade structures on the edges push air to enable cold air to enter the brake, so that air flow passes through, and the fan blade structures rotate to push the air flow soas to enhance the air-cooling heat dissipation effect.

    一种用于高速车辆制动的电磁涡流制动装置,属于高速车辆制动技术领域,装置由励磁单元、外壳装置、转子装置组成,装置结构新颖,工作原理清晰,利用励磁单元提供稳定可靠的制动力,产生在励磁绕组上的热量大部分直接通过水冷系统直接排出,小部分通过风冷系统排出制动器外,励磁单元边缘开风道口,使气流路径达到最长,散热更加充分,外壳为回转结构,其上加装多个散热肋,有助于内部热量的排出;转子散热结构的散热片与转子一体化,其产生的涡流热通过肋板散出;肋板边缘设计成扇叶结构,当制动时转子散热片回转,其边缘的扇叶结构推动空气,使冷空气进入制动器内部,一方面使气流通过,另一方面自身回转推动气流,加强风冷散热效果。
