Bogie and rail vehicle

A bogie, comprising:

• a framework, a wheel pair connected to the framework, a braking hanger fixed to the framework, a hanger slider configured to be fixedly connected to a vehicle wheel braking clamp, and a transmission member,
• wherein:
• the hanger slider is connected to the braking hanger, the transmission member is connected to the hanger slider, a first end of the transmission member extends to a side surface of a vehicle wheel in the wheel pair, and the transmission member is configured to drive the hanger slider to move along a transverse direction with respect to the braking hanger when the first end is subjected to a thrust applied in the transverse direction by the vehicle wheel, so that the vehicle wheel braking clamp moves to a position corresponding to the vehicle wheel,
• the hanger slider comprises:
• a substrate plate connected to the vehicle wheel braking clamp, and a first guiding structure arranged on the substrate plate,
• the braking hanger comprises:
• a base connected to the framework, and a second guiding structure arranged on the base,
• the first guiding structure is connected to the second guiding structure, and movable along the transverse direction with respect to the second guiding structure, and
• wherein the substrate plate is provided with an adjusting mechanism arranged between the substrate plate and the transmission member, which is configured for adjusting transverse displacement of the transmission member to maintain a preset distance between the first end of the transmission member and the vehicle wheel.

A rail vehicle, comprising a bogie, the bogie comprising:

• a framework, a wheel pair connected to the framework, a braking hanger fixed to the framework, a hanger slider configured to be fixedly connected to a vehicle wheel braking clamp, and a transmission member,
• wherein:
• the hanger slider is connected to the braking hanger, the transmission member is connected to the hanger slider, a first end of the transmission member extends to a side surface of a vehicle wheel in the wheel pair, and the transmission member is configured to drive the hanger slider to move along a transverse direction with respect to the braking hanger when the first end is subjected to a thrust applied in the transverse direction by the vehicle wheel, so that the vehicle wheel braking clamp moves to a position corresponding to the vehicle wheel,
• the hanger slider comprises:
• a substrate plate connected to the vehicle wheel braking clamp, and a first guiding structure arranged on the substrate plate,
• the braking hanger comprises:
• a base connected to the framework, and a second guiding structure arranged on the base,
• the first guiding structure is connected to the second guiding structure, and movable along the transverse direction with respect to the second guiding structure,
• the first guiding structure is a guiding block, and the second guiding structure is a guiding frame for receiving the guiding block,
• a receiving space is provided between the guiding block and the substrate plate,
• the guiding frame comprises a top plate, a bottom plate inserted into the receiving space, and a side plate connected between the top plate and the bottom plate,
• an inner surface of the top plate of the guiding frame facing the bottom plate is provided with an elastic guiding mechanism,
• a top surface of the guiding block is recessed inwardly to form a wave-shaped guiding groove with more than two wave troughs, and the elastic guiding mechanism is configured to abut against a surface of the wave-shaped guiding groove.
