  • Patent number: 11592082
    Abstract: A work vehicle transmission includes a first transmission mechanism that changes input motive power to any one of multiple speeds, and a second transmission mechanism that changes the motive power changed by the first transmission mechanism to any one of multiple speeds, the number of speeds of the second transmission mechanism being smaller than that of the first transmission mechanism. Multiple speed change multi-disc clutches of the first transmission mechanism are arranged parallel with multiple deceleration multi-disc clutches of the second transmission mechanism so as to be adjacent in the diameter direction thereof.
    Type: Grant
    Filed: November 19, 2020
    Date of Patent: February 28, 2023
    Assignee: Kubota Corporation
