  • Publication number: 20170284510
    Abstract: A dual clutch transmission comprises a housing formed therein with a gear chamber incorporating an odd-numbered speed gear train group and an even-numbered speed gear train group. An end of the input shaft is connected to an engine, and a cover is detachably attached to the housing opposite the end of the input shaft so as to define a clutch chamber divided from the gear chamber. A first clutch for the odd-numbered speed gear train group and a second clutch for the even-numbered speed gear train group are disposed in the clutch chamber. Fluid passages for supplying hydraulic fluid to the first and second clutches are formed in the cover.

  • Patent number: 9549504
    Abstract: Transaxle systems for a vehicle are disclosed where each of right and left transaxle units includes a hydraulic pump, a hydraulic motor and a casing incorporating the hydraulic pump and motor. Each hydraulic pump has a pump displacement control means operatively connected to a pump control arm pivoted on the casing, and each hydraulic motor has a motor displacement control means operatively connected to a motor control arm pivoted on the casing. A single motor controlling manipulator is operatively connected to the motor control arms to simultaneously shift the motor displacement control means of the right and left transaxle units between large displacement positions and small displacement positions.
