  • Patent number: 8676454
    Abstract: The shift control unit executes a control to cause the through speed ratio to follow the final through speed ratio by changing only the speed ratio of the variator if a shift instruction is given from the driver a plurality of times in a row when the manual mode is selected, and advances the start of a change in the speed ratio of the sub-transmission mechanism or accelerates the progression of the change of the speed ratio as compared with the case where the manual mode is not selected when the speed ratio of the variator is maximized or minimized and the through speed ratio cannot follow the final through speed ratio.

  • Patent number: 8662273
    Abstract: A dual clutch for coupling an engine-side input shaft with a first transmission-side and/or a second transmission-side output shaft. A first clutch has a first pressure plate, which is axially mobile relative to a first counter plate, for coupling with a first clutch disk connected to the first output shaft. A second clutch has a second pressure plate, which is axially mobile relative to a second counter plate, for coupling with a clutch disk connected to the second output shaft. A clutch cover is connected to the first and second counter plates. An actuator displaces the first and/or the second pressure plate. The actuator is radially supported on the input side on the input shaft by the clutch cover and a torsional vibration damper, which is connected to the clutch cover and is radially mounted on the output side on one of the output shafts and/or on a transmission housing.

  • Patent number: 8657091
    Abstract: A clutch device which transmits torque by causing multiple friction engagement elements to engage with each other by use of a clutch connection/disconnection member caused to operate by an electric actuator includes: an elastic member disposed between the clutch connection/disconnection member and the multiple friction engagement elements; position detector for detecting a position of the clutch connection/disconnection member; and controller for controlling an operation of the electric actuator on the basis of the position of the clutch connection/disconnection member detected by the position detector. Thus, the position of the clutch connection/disconnection member (i.e. a stroke amount of the elastic member) and a torque transmission capacity of the clutch device have a linear relationship with each other. Hence, the torque transmission capacity of the clutch device can be accurately controlled by the electric actuator.

  • Publication number: 20140048373
    Abstract: A dual clutch transmission for motor vehicles, with two subtransmissions, with a dual clutch, with a central disk (3) connected to the driving disk (2) and belonging to the dual clutch, with two outer pressure plates (4, 5) and with friction disks (6, 7) which are arranged between the central disk (3) and the pressure plates (4, 5) and which can be coupled individually to the central disk (3) and transfer the torque selectively to the sub transmissions via one of the clutch output shafts (solid shaft 10, hollow shaft 11). Dual clutch transmissions often suffer from noise and vibration problems which mostly arise during crawling actions, when starting from a standstill, in load alternation processes and during gear changes. In order to avoid this, the central disk (3) is decoupled from the driving disk (2) and is mounted on the hollow shaft (11); furthermore, the central disk (3) is connected cardanically to the driving disk (2).

  • Patent number: 8631920
    Abstract: An apparatus for transferring torque from a crankshaft to a dual input transmission includes: a flywheel connected at one end to the crankshaft and at the opposite end to a torque transmitting device or dual clutch. The flywheel has a first coupling member that is configured to engage a second coupling member attached to a center plate of the dual clutch. The first coupling member is fixedly secured to the second coupling member by a fastening means. A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch.

  • Patent number: 8616356
    Abstract: A friction clutch device for coupling a first rear motor shaft to a second front forced shaft by allowing free relative axial displacement between the two shafts. The clutch device includes a double shock-absorbing steering wheel having a primary couple input assembly which is fixedly mounted axially to the motor shaft, a secondary couple output assembly which is rotatably connected to a reactive plate of the clutch device which is supported by the forced shaft. An elastic circumferential action member is arranged in a cavity that is peripheral to the primary assembly to rotatably connect the secondary assembly, with circumferential shock absorption, to the primary assembly. The secondary assembly is fixedly mounted axially relative to the reactive plate.
