The present invention relates to a damper for a rail vehicle, the damper comprising a cylindrical housing (1) wherein a hollow piston (2) is received axially movable, a working chamber (5) of variable volume in the housing, a overflow chamber (4) of variable volume in the piston, the hydraulic overflow chamber (5) being connected to the hydraulic working chamber (5) via a throttle (8) that is in a flow passage between the working chamber (5) and the overflow chamber (4), a spring chamber (3) of variable volume in the piston, the spring chamber (3) being configured to hold a gas volume for acting as a spring, and the spring chamber being separated from the hydraulic overflow chamber (4) by a separator piston (6) that is axially movable, and the damper further comprising a pressure detector (7) that is configured to detect a pressure in at least one of the spring chamber (3), the working chamber (5) and the overflow chamber (4). The invention also relates to a monitoring system and to a method for monitoring a pressure in a damper.
本发明涉及一种用于轨道车辆的阻尼器,该阻尼器包括‑圆柱形壳体(1),其中,中空活塞(2)以可轴向移动的方式被接收,‑在该壳体中的一个可变体积的工作腔(5),‑在活塞中的可变体积的溢流腔(4),液压溢流腔(5)经由位于工作腔(5)和溢流腔(4)之间的液流通道中的节流阀(8)连接到液压工作腔(5),‑在所述活塞中的可变体积的弹簧腔(3),所述弹簧腔(3)被配置成保持用作弹簧的气体体积,并且所述弹簧腔通过能够轴向移动的分离活塞(6)与所述液压溢流腔(4)分离,并且所述阻尼器还包括压力检测器(7),所述压力检测器被配置成检测所述弹簧腔(3)、所述工作腔(5)和所述溢流腔(4)中的至少一者中的压力。本发明还涉及一种用于监控阻尼器中的压力的方法和监控系统。
