摘要： A secondary suspension for a rail vehicle truck is arranged between a suspension support connected to the car body of the vehicle and a spring support. It comprises several spring groups, whose spring elements each have a set of coil springs held by an upper and a lower spring plate and a metal-rubber spring element and are individually interchangeable. The spring elements are designed so that replacement of the spring groups can be carried out with the truck installed on the vehicle and without using a pressure stand or a lift. This goal is achieved by the fact that there are at least two diametrically opposed holder claws for spring tension holders on the upper and the lower spring plate of the spring groups, to which the spring tension holders are attached when the spring elements are compressed.

摘要： An undercarriage with a wheel set capable of self-steering independent of the vehicle body is disclosed. The undercarriage contains, in combination with hollow profile wheels in the wheel sets and primary elastic springs in the longitudinal direction, two lever systems which are self-adjusting, independent of each other and are arranged on the longitudinal sides of an undercarriage. The lever systems forcibly couple the axle ends of the wheel sets on the same rail in the longitudinal direction of the undercarriage and are movable only in opposite directions. The levers are further provided with a reversing member tiltably supported at the truck frame, the tilting motions of which are damped by a single damper assigned to each lever system, whereby in a structurally simple, rugged and low-maintenance manner, optimum limitation of the wheel set's freedom of motion relative to the truck frame is achieved in the longitudinal frame direction with respect to radial self-adjustment in track curves and, at the same time, high stability at high speeds is achieved.
摘要翻译：公开了一种具有能够独立于车体自行转向的车轮的底架。起落架与车轮组中的中空轮廓和纵向上的主弹性弹簧组合包括两个独立于彼此并且布置在起落架的纵向侧上的自调节的杠杆系统。杠杆系统将车轮组的轴端部沿着起落架的纵向强制地联接在相同的轨道上，并且仅在相反的方向上可移动。杠杆还设置有可倾斜地支撑在卡车框架处的反转构件，其倾斜运动被分配给每个杠杆系统的单个阻尼器阻尼，由此在结构上简单，坚固和低维护的方式下，最佳限制在轨道曲线上相对于径向自调节的纵向框架方向实现轮组相对于卡车框架的运动自由度，并且同时实现高速下的高稳定性。
