摘要： This invention relates to a bogie (10), including a load bearing point (11), a wheel set portion (12) and an intervening spring suspension (13). A load weigh valve (15) is fixed between the load portion (11) and the spring (16) of the suspension (13). The valve (15) is mounted within a wedge element (19) so that it continually measures the vertical load.

摘要： A suspension for a rail vehicle includes a bogie pedestal 10, an axle box 11 and suspension springs 16, 18 and 19 arranged such that the axle box supports load exerted on the pedestal via the springs. The suspension includes a pair of wedge elements 20 urged, by means of springs 18 and 19, into engagement with faces 30 of the pedestal and faces 21 of the axle box. This engagement causes damping of axle box movements. Wedge elements 20 are urged resiliently in opposing directions A and B into frictional slidable contact at the faces 21 by means of additional preset springs 40 mounted at the pedestal 11. This further urging is independent of the load carried by the springs and provides improved suspension characteristics.
摘要翻译：用于轨道车辆的悬架包括转向架基座10，轴箱11和布置成使得轴箱经由弹簧施加在基座上的负载的悬挂弹簧16,18和19。悬架包括通过弹簧18和19与基座的表面30和轴箱的表面21接合的一对楔形元件20。这种啮合会导致轴箱运动的阻尼。楔形元件20被弹性地沿着相反的方向A和B通过安装在基座11上的附加的预设弹簧40在表面21处摩擦滑动接触。这种进一步的推动与弹簧承受的负载无关，并提供改善的悬挂特性。

摘要： A suspension for a rail vehicle includes at least one spring (18) carrying a wedge element (20) constrained to move in a vertical direction and a load application member (24) for engaging the wedge (20) to transmit the load to the wedge (20) along a direction. The damping ration of the suspension is variable by altering the engagement between the load application member (24) and the wedge (20) and hence the direction.
摘要翻译：用于轨道车辆的悬架包括至少一个弹簧（18），其承载约束在垂直方向上移动的楔形元件（20）和负载施加构件（24），用于接合楔形件（20）以将负载传递到楔形件（20）。通过改变载荷施加构件（24）和楔形件（20）之间的接合以及因此改变方向，可以改变悬架的阻尼比。
