  • Patent number: 11788607
    Abstract: A transmission, such as a transmission for a vehicle, a driveline including the transmission, and a method of performing a gear shift using the transmission. The transmission comprises a first transmission shaft, a first gear disposed on the first transmission shaft, a first wet clutch, and a first synchronizer. The first wet clutch and the first synchronizer are configured to selectively drivingly engage the first gear with the first transmission shaft and are connectable in series between the first gear and the first transmission shaft, such that the first gear is drivingly engaged with the first transmission shaft only when both the first wet clutch and the first synchronizer are engaged, and such that the first gear is drivingly disengaged from the first transmission shaft when either one or both of the first wet clutch and the first synchronizer is/are disengaged.

  • Publication number: 20230103830
    Abstract: Methods and systems are provided for a dual motor electric transmission configured with two dual synchronizers to reduce torque interruption during gear shifting. In one example, a method may include dropping torque of a first electric motor, allowing a first synchronizer to shift from a first gear arrangement to a second gear arrangement, and compensating for dropped torque with a second electric motor. The method may be repeated to shift a second synchronizer from the first gear arrangement to the second gear arrangement, allowing uninterrupted torque supply during gear shifting.

  • Publication number: 20220163074
    Abstract: Methods and systems are provided for wet clutch pressure control to reduce drag and degradation of rotary seals in a transmission. In one example, a method may include determining an upper threshold pressure based on a rotational speed of a shaft of the transmission, determining a lower threshold pressure based on the rotational speed of the shaft, and adjusting a pressure of hydraulic fluid applied to the clutch to be between the upper threshold pressure and the lower threshold pressure. In this way, the pressure of the hydraulic fluid applied to the clutch may be maintained at a level that allows full torque transfer by the wet clutch while reducing drag on the rotary seals.
