A high temperature brake drum, brake drum body comprises a cylindrical metal or metal alloy, in the brake drum are arranged in the cavity in the cavity to strengthen the partition, strengthen the partition will be divided into a plurality of small cavity cavity communicated with each other, each small cavity and the annular channel is communicated with an integral cavity. The outer wall of the brake drum is provided with a filling hole and a safety pressure limiting exhaust hole. Filling phase change material into the inner cavity of the brake drum through the filling hole. The phase change material absorbs the heat generated by the friction of the brake drum when the vehicle is braked, so as to achieve the purpose of controlling the temperature of the brake drum and protecting the safety performance of the brake drum. The utility model has the advantages of reasonable design, phase change material cooling temperature control effect is obvious, not only solves the problem of brake drum brake brake in high temperature lead to performance degradation or brake failure problem, but also solve the traditional brake drum cooling water to the damage caused on the road, easy to use, reliable performance, can effectively ensure the normal work of the brake drum.
【技术实现步骤摘要】
本技术涉及一种车辆配件的结构,一种相变控温车辆制动鼓。
技术介绍
近年来,制动鼓残片伤人事件时有发生。导致制动鼓残片伤人的原因是车辆在行驶过程中不断地制动刹车,制动刹车产生高温导致制动鼓安全性能降低和使用寿命缩短,制动鼓达到一定的疲劳程度时就会在机械力的作用下产生破损并飞射出来,最终造成严重的安全事故。常见的给制动鼓冷却的办法是不断地给制动鼓浇水,但浇水会污染环境破坏道路,在使用中还要寻找水源给水箱加水,比较麻烦。
技术实现思路
本技术旨在提出一种相变控温制动鼓,在制动鼓本体设加注相变材料的内部空腔。这种相变控温制动鼓,包括金属或金属合金的圆筒状的外壁⑴与内衬(2),在外壁⑴与内衬⑵之间设有内部空腔(3),内部空腔(3)用加强隔板⑷分割为若干相互连通的小空腔(5),小空腔(5)与环形槽道空腔(6)连通构成整体内部空腔(3)。其特征在于,所述的内部空腔在制动鼓外壁设有加注孔(7)和安全限压排气孔(8)。通过加注孔(7)往制动鼓内部空腔(3)中加注相变材料。相变材料吸收制动鼓在车辆制动时由于摩擦产生的热量,从而达到控制制动鼓温度,保护制动鼓安全性能的目的。本技术设计合理,相变材料降温控温效果明显,既解决了制动鼓在刹车时产生高温导致刹车性能下降或制动失效的问题,也解决了传统的给制动鼓浇水冷却降温对路面造成的损坏,使用方便,性能可靠,可有效保证制动鼓正常工作。本技术相变控温制动鼓可用于一切鼓式制动车辆。附图说明图1为相变控温制动鼓的轴向A-A面结构主剖视图。图2为相变控温制动鼓的轴向B-B面结构剖视图。图3为相变控温制动鼓的俯视结构剖视图。具体实施方式如图1所示,本技术 ...
