The invention provides a buffer and a railway vehicle, the buffer comprises a rubber elastic system, the rubber elastic system comprises a plurality of layers of rubber units which are sequentially stacked in the axial direction, and the rubber elastic system further comprises a pre-compression device; at least one layer of the multiple layers of rubber units is pre-compressed by the pre-compression device to form a pre-compressed rubber unit, and at least one layer of the multiple layers of rubber units is a natural rubber unit which is not pre-compressed. The buffer further comprises a friction system, the resistance force of the buffer is mainly provided by a rubber elastic system, and the friction system only provides a small part of resistance force. Furthermore, a quick release hole is formed in the shell, and a stop part is arranged on a supporting seat of the friction system. The buffer can meet the use requirements of railway vehicles, the overall stability is high, the friction block of the friction system can be rapidly detached, and therefore the maintenance efficiency of the friction system is high.
本申请提供一种缓冲器及铁道车辆,该缓冲器包括橡胶弹性系统,所述橡胶弹性系统包括沿轴向依次叠置的多层橡胶单元,所述橡胶弹性系统还包括预压缩装置,所述多层橡胶单元中至少一层被所述预压缩装置预压缩成为预压缩橡胶单元,所述多层橡胶单元中至少一层为未被预压缩的自然橡胶单元。进一步包括摩擦系统,缓冲器的阻抗力主要由橡胶弹性系统提供,而摩擦系统仅提供一小部分阻抗力。进一步在外壳上设置快拆孔,在摩擦系统的支撑座上设置止挡部。该缓冲器能够满足铁路车辆的使用需求,整体稳定性较高,摩擦系统的摩擦块能够快速拆卸下来,因而摩擦系统的维护效率高。
