The invention discloses a flexible foundation brake device of a three-axle bogie and the three-axle bogie. The flexible foundation brake device of the three-axle bogie comprises a combined brake beam unit, a flexible brake unit and a lever guide unit, the combined type brake beam unit comprises a first combined type brake beam, a second combined type brake beam and a third combined type brake beam; the flexible brake unit is a flexible connecting rod mechanism which is flexibly connected with the first combined brake beam, the second combined brake beam and the third combined brake beam respectively; the lever guiding unit is arranged above the sleeper beam and located below the flexible braking unit, and the lever guiding unit is arranged to be in movable contact with the flexible braking unit through a limiting structure and used for guiding the flexible braking unit. According to the flexible foundation braking device, flexible connection can be fully utilized to solve the problems that a lever braking device is poor in relieving and blocking and clamping stagnation occur in the braking relieving process, and the curve trafficability of the three-axle bogie is improved.

    本发明公开了一种三轴转向架柔性基础制动装置及三轴转向架,该三轴转向架柔性基础制动装置包括组合式制动梁单元、柔性制动单元和杠杆导向单元;组合式制动梁单元包括第一组合式制动梁、第二组合式制动梁和第三组合式制动梁;柔性制动单元为柔性连杆机构,其分别与第一组合式制动梁、第二组合式制动梁和第三组合式制动梁柔性连接;杠杆导向单元设置于枕梁的上方并位于柔性制动单元的下方,其设置为与柔性制动单元之间通过限位结构可活动式接触,用于对柔性制动单元进行导向。本发明的柔性基础制动装置可以充分利用柔性连接而解决杠杆制动装置缓解不良和制动缓解过程中出现的受阻与卡滞问题,提高三轴转向架曲线通过能力。
