  • Multi-speed automatic transmission
    Patent number: 8951160
    Abstract: An multi-speed automatic transmission providing at least nine forward speeds and one reverse speed, includes four planetary gear sets, six shift control elements, an input shaft, an output shaft, and a transmission case. Each planetary gear set includes a sun gear, a pinion gear set, a carrier that rotatably supports the pinion gear set, and a ring gear. A carrier of a first planetary gear set is connected to the ring gear of a second planetary gear set and a carrier of the second planetary gear set is connected to the ring gear of the first planetary gear set. The first and second planetary gear sets are concentrically arranged in a common plane.

  • Hydraulic Free Multispeed Transmissions for Electric Vehicles and Fuel Cell Hybrid Vehicles and Systems for Shifting the Same
    Publication number: 20120149520
    Abstract: A multispeed transmission includes a sun gear, at least one high-speed planetary gear in constant mesh with the sun gear and a high-speed ring gear, where the high-speed planetary gear orbits around the sun gear. The multispeed transmission also includes at least one low-speed planetary gear coupled with the high-speed planetary gear and in constant mesh with a low-speed ring gear and a carrier rotationally engaged with the high-speed planetary gear and the low-speed planetary gear such that either the high-speed planetary gear or the low-speed planetary gear controls rotation of the carrier. The multispeed transmission further includes a transmission case that surrounds the high-speed ring gear and the low-speed ring gear and a clutch located proximate to the high-speed ring gear and the low-speed ring gear, where the clutch selectively couples the high-speed ring gear or the low-speed ring gear with the transmission case.
