    • An integrated assembly useful for controlling a variable speed drive having a housing and a control shaft projecting therefrom. The control assembly consists of a control arm fixed on the control shaft to effect its rotation; a return to neutral mechanism disposed about the control shaft to bias the control shaft to a neutral position; and a rotary, viscous fluid damper integrated with the return to neutral mechanism, the damper having a rotor engaged to the control shaft and a stator fixed to the housing of the variable speed drive to moderate, or slow the rotational movement of the control shaft under the influence of inputs from the control arm and the return to neutral mechanism. The neutral arm of the return to neutral mechanism is integrally formed with the external case of the rotary, viscous fluid damper, creating a compact control mechanism.
    • 一种用于控制具有壳体的变速驱动器的集成组件和从其突出的控制轴。 控制组件由控制臂固定在控制轴上以实现其旋转; 设置在控制轴周围的返回到中立机构以将控制轴偏置到中立位置; 以及一个与返回到中立机构一体的旋转粘性流体阻尼器,该阻尼器具有与控制轴接合的转子和固定到变速驱动器的壳体上的定子,以适应或减慢下述控制轴的旋转运动 控制臂的输入和中立机制的影响。 返回中立机构的中立臂与旋转式粘性流体阻尼器的外壳形成一体,形成紧凑的控制机构。

    • A variable speed drive includes a transmission in a housing with a rotatable control shaft for moving the transmission between neutral and drive positions. A rotary damper is engaged to an external control arm which rotates the control shaft. A return to neutral mechanism is engaged to the control shaft to return the transmission to neutral. The external damper may be a viscous fluid damper having a plate, a rotor element with a first set of concentric projections, and a stator element with a second set of concentric projections that mesh with the first set of concentric projections. A method is provided for assembling a damper subassembly and a return arm subassembly, and connecting the damper subassembly to the housing, connecting the control arm to the control shaft and connecting the return arm subassembly to the control shaft for ease of assembly.
    • 变速驱动器包括具有可旋转控制轴的壳体中的变速器,用于在中性位置和驱动位置之间移动变速器。 旋转阻尼器接合到使控制轴旋转的外部控制臂。 返回中立机构接合到控制轴以将变速器返回中立。 外部阻尼器可以是具有板的粘性流体阻尼器,具有第一组同心突起的转子元件和具有与第一组同心突起啮合的第二组同心突起的定子元件。 提供了一种用于组装阻尼器组件和返回臂子组件的方法,并将阻尼器组件连接到壳体,将控制臂连接到控制轴并将返回臂子组件连接到控制轴以便于组装。
