The invention relates to the field of metallurgical transport vehicles, in particular to a bogie for a coke quenching car, which is characterized by comprising a framework, axle boxes, wheel pairs, braking devices and damping devices, the framework is an I-shaped component formed by welding end beams and sleeper beams, and the end beams are connected with the axle boxes through the damping devices; the damping device at one end of the wheel pair comprises two spring groups, and each spring group comprises an inner spring and an outer spring; the braking device is a unit brake; g-shaped wheels are arranged on the wheel pairs. The invention has the following beneficial effects: 1) the G-shaped wheels are adopted, so that the bearing capacity is improved to 100t, and the labor productivity is greatly improved; and (2) a sleeved coil spring vibration reduction structure is adopted, so that enough deformation is improved for the car body, and the running performance and safety of the quenching car can be obviously improved when the bogie is subjected to large bending moment and running fluctuation. The unit brake is adopted to replace a brake beam type braking structure, the structure is greatly simplified, the brake shoe is convenient to replace after being abraded, and the braking effect is stable.

    本发明涉及冶金运输车辆领域,尤其涉及一种熄焦车用转向架,其特征在于,包括构架、轴箱、轮对、制动装置和减振装置,构架由端梁和枕梁拼焊而成的工字形构件,端梁通过减振装置与轴箱相连接;轮对一端的减振装置为两组弹簧组,包括一个内簧和外簧;制动装置为单元制动器;轮对上为G型车轮。本发明的有益效果是:1)发明采用G型车轮,将承重提升至100t,大幅提升了劳动生产率。2)采用套装的圆簧减振结构,为车体提升了足够的变形量,在转向架受到较大弯矩及运行波动时,能显著提升熄焦车运行性能及安全性。3)采用单元制动器替代制动梁式制动结构,结构大为简化,闸瓦磨损后更换方便,制动效果稳定。
