The invention belongs to the technical field of railway vehicles, and particularly relates to a gauge-changeable bogie. The bogie comprises wheel set assemblies, a framework and a brake device, wherein the two wheel set assemblies are oppositely arranged on the framework; the brake device comprises a unit brake and a brake shoe; the unit brake is fixedly installed on the side face of a cross beamassembly; the brake shoe is installed on a push rod base of the unit brake; and the brake shoe operably acts on a friction ring of a locking mechanism so as to control rotation of the wheel set assemblies. The brake device is fixed relative to the axle, so that the influence of the change of the distance between the inner sides of the wheels on braking can be avoided.
本发明属于铁路车辆技术领域,尤其涉及一种变轨距转向架。其包括轮对组成、构架以及制动装置,两个轮对组成相对设置在构架上,其中的制动装置包括单元制动器和闸瓦,单元制动器固定安装在横梁组成的侧面上,闸瓦安装于单元制动器的推杆座上,闸瓦可操作地作用在锁定机构的摩擦环上,以控制轮对组成的转动。本发明中的制动装置是相对车轴固定的制动方式,进而可避免车轮内侧距改变对制动的影响。
