  • Patent number: 10372153
    Abstract: A lever device includes a housing and a lever unit pivotally coupled to the housing. The lever unit includes a lever shaft and a pivot shaft that extends in a direction intersecting the lever shaft. The pivot shaft functions as a pivot axis of the lever unit when the lever is pivoted in a first direction. The housing includes a retainer that accommodates the pivot shaft. The pivot shaft includes first and second guides. The first guide slides on the retainer when the lever unit is pivoted in the first direction to permit movement of the lever unit. The second guide that slides on the retainer when the lever unit is operated in a second direction to permit movement of the lever unit.

    Abstract: This manual transmission includes a connection changeover mechanism which changes the state of connection between the output shafts of the motor generator and the transmission in accordance with a gear stage established by a driver's shift lever operation. When a gear stage for low speed travel is established, a power transmission system is established between the output shafts of the motor generator and the transmission, and the motor speed reduction ratio is set to a first speed reduction ratio. When a gear stage for intermediate speed travel is established, a power transmission system is established between the output shafts of the motor generator and the transmission, and the motor speed reduction ratio is set to a second speed reduction ratio. When a gear stage for high speed travel is established, no power transmission system is established between the output shafts.

    Abstract: In a shift lever device, a first engagement portion or a second engagement portion of a shift lever is inserted into a first stopping hole or a second stopping hole of a strength gate when the shift lever is turned along a manual transmission hole, thereby stopping the shift lever from turning towards an automatic transmission hole side. In the shift lever, the first engagement portion and the second engagement portion are disposed at the vehicle front side and the vehicle rear side of a support body. An increase in size of the shift lever in the vehicle left-right direction due to the first engagement portion and the second engagement portion can accordingly be suppressed, and the turning rage of the shift lever in the vehicle left-right direction can be made smaller, thereby enabling a reduction in size of the shift lever device in the vehicle left-right direction.

  • Patent number: 8726755
    Abstract: In a shift lever device, a first-link is held at a permitting-position due to a release button being operated. Therefore, when a shift lever is operated from a “P” shift position, when a second-link is pushed toward a vehicle right side by the shift lever, even if a magnet is not energized, the second-link is rotated in a state where sliding of the first-link toward a vehicle right is impeded. Operation of the shift lever from the “P” shift position is thereby forcibly permitted. Here, the first-link is disposed at the permitting-position that is an initial-position, and, due to the release button being operated, the first-link is held at the permitting-position. Therefore, there is no need to move the first-link by operation of the release button, and the operation load and operation stroke of the release button can be made to be small.

Next, a previously engaged first driving direction clutch, driving the vehicle in the first driving direction, is disengaged and a second driving direction clutch, for driving the vehicle in the second driving direction, is engaged so that a speed of the vehicle, in the first driving direction, is reduced and a speed of the vehicle, in the second driving direction, is subsequently accelerated, whereby the drive motor is operated at a higher rotational speed during the reversal process.

  • Patent number: 8726750
    Abstract: A mechanism for actuating a shifting element. A first shifting element half of a brake is axially fixedly connected to a drive machine output shaft, which, when rotational movement of the output shaft equals the disengaging movement of the shifting element, is rotationally fixed to the output shaft. In the event of an engaging force, opposite the disengaging movement of the shifting element, an axial force acts on the output shaft, such that the first shifting element half frictionally engages with an axially and rotationally fixed second shifting element half. In the event of a disengaging force that acts in the disengaging direction of the shifting element, an axial force acts on the motor output shaft such that the first shifting element half of the brake is moved out of frictional engagement with the second shifting element half.

  • Patent number: 8613236
    Abstract: In a shift lever device, even when a magnet is immovably installed, the shift lever device can shift a shift lever between blocking and allowing operation from a “P” shift position to an “R” shift position because a first link and a yoke plate are slidable, a second link is rotatable with respect to the first link, and the magnet switches between attraction and non-attraction with respect to the yoke plate. For this reason, the magnet can be immovably installed.

  • Patent number: 8583336
    Abstract: First and second clutches correspond to systems which include “first gear” and “second gear,” respectively. When the temperature of the first clutch at the time of start of the vehicle is lower than a first temperature, only the first clutch is used as a start clutch for driving the vehicle. When the temperature of the first clutch is not lower than the first temperature but is lower than a second temperature, both the first and second clutches are used as the start clutch. When the temperature of the first clutch is equal to or higher than the second temperature, only the second clutch is used as the start clutch. Thus, the higher the temperature of the first clutch, the smaller the load acting on the first clutch. When the temperature of the second clutch is high, engine torque is reduced, and a warning is issued.
