    • An air-free, relatively lightweight lift assembly for an axle/suspension system of a highway/rail convertible semi-trailer, utilizes a transversely-oriented coil torsion spring having a relatively low spring rate. The torsion spring is captured between a stationary plate and a rotatable plate. A flexible link is pivotally attached at its upper end to the rotatable plate and at its lower end to the axle. This assembly results in a variable rate moment arm and continuously increasing leverage when the suspension air spring is overinflated to lower the system for transfer of the trailer from a highway tractor to a rail bogie, thus enabling use of a less robust air spring. The assembly conversely creates a decrease in leverage at the lifted rail transport position, to securely maintain the axle/suspension system in the rail position. For highway use, the lift assembly provides suspension damping without shock absorbers.
    • 用于公路/轨道式可转换半挂车的轴/悬挂系统的无空气相对轻的提升组件利用具有相对较低弹簧刚度的横向取向线圈扭力弹簧。 扭转弹簧被捕获在固定板和可旋转板之间。 柔性连杆在其上端可枢转地附接到可旋转板并且在其下端枢转地连接到轴。 当组合悬挂空气弹簧被过度膨胀以降低系统以将拖车从高速公路拖拉机转移到轨道转向架时,该组件产生可变速率力矩臂和不断增加的杠杆作用,从而能够使用不那么坚固的空气弹簧。 组件相反地在提升的轨道运输位置产生杠杆作用的降低,从而将轴/悬挂系统牢固地保持在轨道位置。 对于高速公路使用,电梯组件提供无减震器的悬架阻尼。

    • A force applying device such as a spring supporting device comprises a helical compression spring (1) located within a cylindrical housing (3), the device being designed to support a load (8) through a rod (5). In use, the load (8) will move vertically between a high position and a low position, involving compression and extension of the spring (1). One end of the spring is provided with a pair of diametrically projecting trunnions (9), which are located within a pair of diametrically opposed cam tracks (11) provided in the cylinder wall. During initial downward movement of the load, the trunnions engage with the cam track (11), tending to "wind up" the spring, providing an upward force acting on the trunnions. During final movement, movement of the trunnions within the cam track allows the spring to "unwind", and thus some of the work required to be performed during this axial movement of the load produces a downward force compensating the increase in spring reaction. In this manner, by selection of a cam track of appropriate shape, a substantially constant force may be produced acting against the load throughout the range of movement of the spring.

    • An actuator having a bi-directional spring holder assembly is disclosed. The assembly has a substantially cylindrical housing (42) having a projection (60) formed on a rim of its cylindrical wall (56). The projection (60) is provided with first and second abutments (62, 64) facing in opposite directions along the circumference of the rim (58). A spring (70) is mounted around a shaft which passes through a longitudinal axis of the housing. A first, internal spring end (72) is engaged to the shaft while a second, external spring end (74) projects radially outward of the cylindrical wall (56). The assembly also includes a spring cover (80) provided with a cover abutment (84) which similarly projects radially outward of the cylindrical wall (56). When the holder assembly is assembled, the spring (70) is coiled and the cover abutment (84) pushes against the projection's first abutment (62) while the external spring end (74) pushes against the second abutment (64). The actuator housing is provided with a wall member (48), one side of which forms a stop for the cover abutment (84), while the other side serves as a stop for the external spring end (74). When the gear train is driven, one of the cover abutment (84) and the external spring end (74) abut a corresponding stop, and the entire housing (42) rotates with the output lever, causing the spring to coil. The coiled spring then provides a restoring force, returning the output lever to the neutral position.
