Abstract:
1. A transmission comprising: an input shaft, an output shaft, and second, third, and fourth shafts; a first gearing arrangement configured to selectively constrain the third shaft to rotate at a speed between speeds of the input shaft and of the fourth shaft; a second gearing arrangement configured to fixedly constrain the third shaft to rotate at a speed between speeds of the fourth shaft and of the second shaft; a third gearing arrangement configured to selectively constrain the output shaft to rotate at a speed between zero and a speed of the third shaft, and to selectively constrain the input shaft to rotate at a speed between speeds of the third shaft and of the output shaft; a first clutch configured to selectively couple the input shaft to the second shaft; a first brake configured to selectively hold the second shaft against rotation; and a second brake configured to selectively hold the fourth shaft against rotation.
