Title: JOURNAL BOX RUBBER PAD, BOGIE AND RAILWAY CAR
Abstract:
Provided are a journal box rubber pad for a railway car bogie, and a bogie and railway car having said rubber pad, comprising an upper liner (1) and a lower liner (2), distributed vertically. A damping device is provided between the upper liner (1) and the lower liner (2). The damping device is positioned separate from the upper liner (1) and the lower liner (2), or the damping device is formed by the upper liner (1) and the lower liner (2). The damping device is used to convert the kinetic energy of horizontal and/or vertical vibrations of the upper liner (1) and the lower liner (2) into internal energy, thereby reducing vibrational energy and preventing hunting oscillation of wheel pairs caused by vibration, improving operational stability and safety of a railway vehicle.
