  • Automatic transmission having three planetary rows and vehicle
    Patent number: 10948051
    Abstract: An automatic transmission having three planetary rows, which includes an input element and an output element. The input element is fixedly connected to the second sun gear, the output element is fixedly connected to the third planetary carrier, the second planetary carrier is fixedly connected to the third gear ring, the first gear ring is fixedly connected to the third planetary carrier. When the brake is engaged, the elements connected with the brake are braked accordingly. The first rear sun gear is connected to the input element, the second planetary carrier is connected to the third gear ring, and the second clutch is selectively engaged to connect with any two of the second sun gear, the second gear ring and the second planetary carrier, so as to make the second planetary row rotate overall.
