20120149519 | TRANSMISSION ASSEMBLY HAVING VARIABLE FORCE CLUTCH - A transmission assembly for a machine is disclosed. The transmission assembly may have a clutch pack, a first pressure chamber, and a second pressure chamber. The transmission assembly may also have a first piston configured to push against the clutch pack when pressurized fluid is directed into the first pressure chamber, and a second piston configured to push against the first piston when pressurized fluid is directed into the first pressure chamber and inhibited from pushing against the first piston when pressurized fluid is directed into the second pressure chamber. | 06-14-2012 |
20130324350 | DUAL PISTON TRANSMISSION CLUTCH - A transmission assembly may include a first clutch and a second clutch. The second clutch may include a clutch pack, a pressure chamber, a first piston, and a second piston. The first piston may be configured to push against the clutch pack when pressurized fluid is directed into the pressure chamber. The second piston may be configured to push against the first piston when pressurized fluid is directed into the pressure chamber at a time when the first clutch is unactuated and inhibited from pushing against the first piston at a time when the first clutch is actuated. | 12-05-2013 |
20140038765 | Configuration for Compact Five Speed Planetary Transmission - A compact five-speed transmission planetary gear train includes a first, second, third, fourth and fifth planetary gear sets between an input and an output as well as first, second, third and fourth brakes and first and second clutches. The first, second, third and fourth brakes and first and second clutches are selectively actuatable to provide five different forward speeds and a plurality of different reverse speeds between the input and the output. | 02-06-2014 |
20140038766 | Configuration for Compact Five Speed Planetary Transmission - A compact five-speed transmission planetary gear train includes a first, second, third, fourth and fifth planetary gear sets between an input and an output as well as first, second, third and fourth brakes and first and second clutches. The first, second, third and fourth brakes and first and second clutches are selectively actuatable to provide five different forward speeds and a plurality of different reverse speeds between the input and the output. | 02-06-2014 |
20140038767 | Configuration for Compact Planetary Transmission - A compact five-speed transmission planetary gear train includes a first, second, third, and fourth planetary gear sets between an input and an output as well as first, second, and third brakes and first, second and third clutches. The first, second, third and fourth brakes and first and second clutches are selectively actuatable to provide five different forward speeds and a four different reverse speeds between the input and the output. The compact transmission also includes a first brake, second brake, third brake, fourth brake, first clutch, and second clutch associated with the planetary gear train, the first brake, second brake, third brake, fourth brake, first clutch, and second clutch being configured such that setting each forward and reverse speed of the compact transmission is accomplished via actuation of two of the first brake, second brake, third brake, fourth brake, first clutch, and second clutch. | 02-06-2014 |
20140038768 | Configuration for Compact Planetary Transmission - A compact five-speed transmission planetary gear train includes a first, second, third, and fourth planetary gear sets between an input and an output as well as first, second, and third brakes and first, second and third clutches. The first, second and third brakes and first, second and third clutches are selectively actuatable to provide five different forward speeds and a four different reverse speeds between the input and the output. | 02-06-2014 |
20150267780 | Multi Speed Transmission - A multi-speed transmission includes a housing; an input member and an output member; four planetary gear trains including a first planetary gear train, a second planetary gear train, a third planetary gear train and a fourth planetary gear train, wherein each of the planetary gear trains includes a ring gear, a planetary carrier and a sun gear; and six control elements. Each of the six control elements is operatively connected to at least one of the planetary gear trains and selectively engageable to produce a set of different speeds between the input member and the output member. The set of different speeds includes eight forward speeds and two reverse speeds. | 09-24-2015 |
20150267781 | Multi Speed Transmission - A multi-speed transmission includes a housing; an input member and an output member; four planetary gear trains including a first planetary gear train, a second planetary gear train, a third planetary gear train and a fourth planetary gear train, wherein each of the planetary gear trains includes a ring gear, a planetary carrier and a sun gear; and six control elements. Each of the six control elements is operatively connected to at least one of the planetary gear trains and selectively engageable to produce a set of different speeds between the input member and the output member. The set of different speeds includes ten forward speeds and two reverse speeds. | 09-24-2015 |
