Description

适用于高速铁路货车的无摇枕构架式转向架 技术领域
本发明涉及一种货车转向架，特别是指一种适用于高速铁路货车的无摇枕构架式转向架。
背景技术
目前对于快运货车转向架研究已有不少进展，大部分研究重点在满足运行速度160km/h的转向架。为了满足国内铁路货运的需求，需要在160km/h转向架基础上，进一步研制满足最高运行速度200km/h以上的高速货车转向架。
现有的快运货车转向架均采用焊接构架式转向架，主要有三类：带摇动台结构利诺尔减振器定位构架转向架、无摇动台摇枕上置式橡胶堆导柱式定位构架转向架及无摇动台摇枕上置式橡胶弹簧定位构架转向架。
中国专利CN 200620034959.8(公开号CN 200945865Y)公开了一种快速铁路货车转向架，属于无摇动台摇枕上置式构架转向架，其一系悬挂装置采用金属液体橡胶复合弹簧与轴箱定位，摇枕与构架之间的二系悬挂装置采用橡胶堆弹簧，采用常接触双作用滚子弹性旁承，采用两组盘形制动。
中国专利CN 01275171.5(公开号CN 2517641Y)公开了一种高速货车转向架，也属于无摇动台摇枕上置式构架转向架，其一系采用橡胶弹簧导柱式定位，两侧梁之间用两根横梁连接起来，组成一个“H”型构架，也采用盘形制动。
以上两种快运转向架均采用托盘式轴箱定位结构，轴箱弹簧采用金属液体橡胶复合弹簧，三向刚度匹配困难，抑制轮对蛇形运动 能力差，高速运行稳定性较差，采用磨耗件，磨耗后长期高速运行可靠性及维修经济性差等缺点，其最高运行速度均为160km/h。
中国专利申请CN 201110440779.5(公开号CN 102490755A)公开了一种“高速铁路货车转向架”，该转向架采用无摇枕转臂式构架转向架，可满足运行速度200km/h轴重16.5t的要求。该转向架两侧梁通过中央大横梁和两小横梁连接，虽取消了摇枕但设置有中央大横梁，增加了转向架重量和制造难度。
中国专利申请CN201310681744.X(公开号CN 103661463A)公开了一种“一种高速铁路货车转向架”，也是采用了无摇枕转臂式构架转向架，可满足运行速度200km/h的要求。该转向架参照客车转向架，二系弹簧采用空气弹簧结构，结构复杂，不便于安装和检修，造成转向架制造检修维护成本增加。
