Document Type and Number:
WIPO Patent Application WO/2022/096041
Kind Code:
A1
Abstract:
The invention relates to an electric power-split system and a method of operating thereof, with a first electric drive branch comprising a first motor-generator block (59) including a first motor-generator (1), and with a second electric drive branch comprising a second motor-generator block (60) including a second motor-generator (2), wherein the first motor-generator (1) is connectable to the second motor-generator (2). The system comprises a planetary gearset (4) with dual planet gears (46) and four input/output members for altering the flow ratio of the mechanical and electric drive branch, wherein each input/output member is either an input or output member. Each dual planet gear (46) is connected to the four input/output members, which are a first pair of input/output members formed by a first sun gear (41) and a ring gear (44), and a second pair of input/output members formed by a second sun gear (43) and a planet carrier (45). Any one of said two pairs of input/output members comprises two input members of the planetary gearset (4). One of the two input members is connectable to the first motor-generator (1) and the other of the two input members is connected to the second motor-generator (2), whereas the remaining other of said two pairs of input/output members comprises two output members of the planetary gearset (4). The output members of the planetary gearset (4) are connectable to a two-branch output block (38), and mechanically further via the output block (38) to an output shaft (10), wherein each of the output members is connectable to only one of the branches of the output block (38).
