摘要： A railway vehicle truck including side frames and wheel sets maintained in a substantially rectangular relationship by resilient connection means at each of the axle mounts to the side frames. The resilient means are prestressed and in equilibrium at each mounting location so as to resist yaw and lengthwise movement of the axles relative to the side frames. The resilient means provide resistance to hunting motion and yet yieldingly permit relative turning of the axle and side frame when the truck traverses a curved track.
摘要翻译：一种包括侧框架和车轮组件的轨道车辆卡车，其在每个车轴安装件处的侧框架上通过弹性连接装置保持基本上矩形的关系。弹性装置在每个安装位置处被预应力并处于平衡状态，以便防止轴相对于侧框架的偏转和纵向移动。弹性装置提供了对摆动运动的抵抗力，并且当卡车穿过弯曲的轨道时，允许轴和侧框的相对转动。

摘要： A multi-rate side bearing for a railway truck is provided. The side bearing comprises a base plate and an upper plate, with two resilient devices located between the base plate and the upper plate. The resilient devices usually are elastomeric pads of different compression rates and shear stiffness. Under unloaded car conditions, only one pad is in load supporting contact, but under loaded car conditions, both resilient devices contact the upper and base plates to provide load support and car body-truck motion damping.

摘要： A three-piece dampener assembly provides means to depress vertical and horizontal oscillations between ends of a bolster of a railroad car truck and side frames of the truck. This assembly includes a control or friction shoe having an outer vertical engaging surface for contact with a vertical wear plate of a pocket formed in the side frame and an inner projecting triangular-shaped segment. The triangular segment is covered by a relativley low friction adapter and engages a like triangular-shaped wedge slot formed in a control or friction shoe housing. The housing further includes an inclined wear surface for engaging with a complementary inclined friction surface formed in the bolster and a bottom surface for supportive engagement with a coil spring carried in the side frame pocket below the bolster.

摘要： In a railroad car truck an elastomeric device is used to operatively connect each axle end of the wheelsets to a respective pedestal jaw of the side frames. The elastomeric device may comprise an elastic pad affixed between two metal plates. By choosing an elastic material having a relative high stiffness in shear, movements between the wheelsets and side frames are cushioned while at the same time the wheelsets and side frames are held in a substantially squared relationship. The squared relationship improves the dynamic stability of the truck by increasing its critical speed to allow higher speed travel.
摘要翻译：在铁路车辆卡车中，使用弹性体装置将轮对的每个轴端可操作地连接到侧框架的相应的底座钳口。弹性体装置可以包括固定在两个金属板之间的弹性垫。通过选择具有相对高的剪切刚度的弹性材料，轮对和侧框架之间的移动被缓冲，同时轮对和侧框架保持基本平方的关系。平方关系通过提高卡车的临界速度来提高卡车的动态稳定性，以允许高速行驶。

摘要： A railway wheel and axle assembly comprises a journal box with spaced wings extending longitudinally of the railway vehicle away from the axle. Springs supported by said wings accommodate relative lateral, longitudinal, vertical, yaw, pitch and roll movement between the vehicle body and the wheel and axle assembly. The wings comprise brackets longitudinally beyond the springs, and the vehicle body comprises a bracket above and laterally of each wing bracket and aligned therewith for attachment of a single axial displacement damper for damping such movement.

摘要： A truck for a railroad car has a front and rear wheelset with axle ends rotatively carried in a front and rear steering arm, respectively. The steering arms are carried in pedestal jaws of a right and left side frame with resilient pads interfacing between the steering arms and the side frames. The resilient pads allow each wheelset and steering arm to rotate or yaw to an out-of-square condition with respect to the side frame as the railroad car proceeds, for example, around a curve in the track on which the car is traveling. This rotational movement is selectively regulated by a joint connecting the front and rear steering arms.
