摘要： Damping elements physically contact some of the coils on one or more mechanical coil springs disposed between a railway car body and a truck. The coils contacted may be at the ends of the springs or at areas between the ends. When double springs are involved, with one being spaced within the other, the damping elements are disposed in the space between the springs at the ends thereof.

摘要： A mounting member is disposed on one end of a mechanical spring to prevent vibrations from a truck being transmitted into a car body for transmitted to the spring and car body if mounted below the spring. The mounting includes a pair of elastomeric rings, with one of the rings providing vertical compliance and the other providing lateral compliance between the truck and car body.

摘要： A tilt control system comprises a roll bar structure having two separate opposite rotatable members attached on the bottom of both sides of the car body between the car body and bolster. A pair of lever arms connect the ends of the rotatable members to the bolster. Means are provided for selectively rotating the rotatable members to actuate the lever arms in opposite directions to force the car body to tilt laterally with respect to the bolster.

摘要： A laterally disposed cylinder including fluid therein connected between a truck and car body is responsive to lateral forces to provide low damping when relatively low lateral forces are applied and proportionally higher damping as relatively higher lateral forces are applied. The cylinder includes a piston to provide two fluid chambers. The piston includes an opening therein. An element is provided to vary the opening in accordance with the lateral forces.

摘要： An articulated truck joins and supports two adjacent railway cars. A linkage including two pairs of links is connected between the bolster of the truck and one of the railway cars. A common link is connected between the two pairs of link. The linkage and common link forces the truck to maintain a radial position with respect to curves in the track.

摘要： A forced steering mechanism is connected to a truck to steer an axle and associated wheels. Coupling means are provided for loosely connecting the car body of a vehicle to the truck and the forced steering mechanism. The coupling means permits relative lateral movement between the car body and truck while maintaining the forced steering mechanism in a position so as to permit self steering, but no forced steering when the vehicle is moving over tangent or rectilinear tracks. At the same time the degree of such lateral movement and amount of self steering is limited. The coupling means causes the forced steering mechanism to become operative when the vehicle is moving over sharply curved tracks.
摘要翻译： 强制转向机构连接到卡车以转向轴和相关联的车轮。 提供了用于将车辆的车身松散地连接到卡车和强制转向机构的联接装置。 联接装置允许车身和卡车之间的相对横向运动，同时将强制转向机构保持在允许自行转向的位置，但是当车辆在切线或直线轨道上移动时没有强制转向。 同时，这种侧向运动的程度和自动转向的数量是有限的。 当车辆在急剧弯曲的轨道上移动时，联接装置使得强制转向机构变得可操作。
