The invention relates to the technical field of vehicle brake devices, in particular to a brake device and a brake method for a highway and railway dual-purpose tractor. A brake device for a highway and railway dual-purpose tractor comprises a brake hub, a brake shoe, a brake cylinder, a return spring and a mounting plate. A cooling mechanism is further included; the cooling mechanism is arranged in the brake hub and used for cooling the brake hub and the brake shoe; when a worker steps on the brake pedal, the air blower blows out high-pressure air to the friction plate and the brake hub to cool the friction plate and the brake hub, and when the worker stops stepping on the brake pedal, the high-pressure air is blown to the contact surface between the friction plate and the brake hub to blow away chippings and powder generated by abrasion. And the situation that abrasion is increased when chippings and powder brake between the friction plate and the brake hub is reduced.

    本发明涉及车用制动装置技术领域,尤其涉及一种公路铁路两用牵引车用制动装置及制动方法;一种公路铁路两用牵引车用制动装置,包括制动毂、制动蹄、制动缸、回位弹簧和安装板;还包括降温机构;所述降温机构设置在所述制动毂内,用于对所述制动毂和制动蹄进行降温;本发明通过在工作人员踩踏制动踏板时,鼓风机吹出高压气体吹到摩擦片和制动毂上,对摩擦片和制动毂进行降温,再在工作人员停止踩踏制动踏板时,高压气体吹到摩擦片和制动毂之间相互接触的表面,将磨损产生的碎屑、粉末吹去,减少了碎屑、粉末在摩擦片与制动毂之间制动时,使得磨损增加的情况。
