  • Patent number: 11926311
    Abstract: A hybrid driving system and a hybrid electric vehicle. The hybrid driving system includes an engine, an input element (20), an output element (23), a box body (24), a first motor (13), a second motor (14), a first planet row, a second planet row, a third planet row, a first clutch (15) and a first brake (16). According to the hybrid driving system of the present disclosure, a basic three-planet-row planet gear configuration is provided through the planet row mechanical structure and the reasonable layout of multiple operating elements (the clutches and the brakes), which can realize at least two E-CVT working modes to obtain higher transmission efficiency.
    Type: Grant

  • 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.
