The invention belongs to the technical field of bogies, and particularly relates to a locomotive bogie vibration reduction wedge with a stopper, which comprises a bogie body, a side frame upright wearing plate is arranged on the bogie body, a swing bolster inclined surface wearing plate is arranged on the bogie body, and a wedge body is in contact with the swing bolster inclined surface wearing plate. The wedge body is in contact with a side frame stand column wearing plate, the wedge body and the side frame stand column wearing plate are jointly provided with an energy dissipation mechanism, an inner circle spring is welded to the wedge body, and an outer circle spring is welded to the wedge body. Through cooperative use of the first abrasion block and the second abrasion block, the abrasion performance of the wedge can be improved so as to reduce the deformation modulus when the inner circle spring and the outer circle spring reset, under the action of the elastic body, the second abrasion block can be pushed to make contact with the first abrasion block all the time, abrasion of the second abrasion block and the first abrasion block is avoided, and the service life of the wedge is prolonged. And the abrasion performance is weakened.
本发明属于转向架技术领域,具体涉及带止挡机车转向架减振斜楔,包括转向架本体,所述转向架本体上设置有侧架立柱磨耗板,所述转向架本体上设置有摇枕斜面磨耗板,所述摇枕斜面磨耗板上接触有斜楔本体,所述斜楔本体与侧架立柱磨耗板接触,所述斜楔本体和侧架立柱磨耗板上共同设置有耗能机构,所述斜楔本体上焊接有内圆弹簧,所述斜楔本体上焊接有外圆弹簧。本发明通过第一磨耗块与第二磨耗块的配合使用,可提高斜楔的磨耗性能,以降低内圆弹簧、外圆弹簧复位时的形变模量,并在弹性体的作用下,可推动第二磨耗块始终与第一磨耗块接触,避免第二磨耗块、第一磨耗块的磨损,导致磨耗性能减弱的问题。
