    • A power transmission implementing continuously variable transmission using a succession of gear sets. A first constant ratio gear set (62) receives torque and rotation from a motor (40) and a second constant ratio gear set (70) provides torque and rotation to a driven device (44). These two gear - sets each employ three gear elements such that the first gear - set receives power in one shaft and provides power in two shafts. The second gear set receives power in two different shafts and provides power in one shaft. Two drive chains transmit rotation and torque from the first gear - set to the second gear - set, in between the two gear sets the rotation is reversed (72) in one drive chain. A control over the total gearing ratio of the transmission is provided by transient application of power to modify the rotation rate of one branch (74). In one embodiment fluid couplings are employed for transmission of power in each drive chain.
    • 一种使用一系列齿轮组实现无级变速器的动力传动装置。 第一恒定比例齿轮组(62)从马达(40)接收扭矩和旋转,而第二恒定比例齿轮组(70)向被驱动装置(44)提供扭矩和旋转。 这两个齿轮组均采用三个齿轮元件,使得第一齿轮组在一个轴中接收动力并在两个轴中提供动力。 第二齿轮组在两个不同的轴中接收动力,并在一个轴中提供动力。 两个驱动链将旋转和扭矩从第一齿轮组传递到第二齿轮组,两个齿轮组之间的旋转在一个驱动链中反转(72)。 通过瞬时施加电力来改变一个分支(74)的旋转速率来提供对变速器总传动比的控制。 在一个实施例中,使用流体联接器来传输每个驱动链中的动力。
