  • Hybrid driving system and hybrid electric vehicle
    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.
