Title:
DUAL-MOTOR DRIVE SYSTEM AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2023/284141
Kind Code:
A1
Abstract:
A motor drive system comprises a planetary mechanism (7), a first motor (1), a first clutch (13), and a wheel shaft (20). The planetary mechanism (7) comprises a sun gear (701), a ring gear (704), multiple planet gears (702), a planet carrier (703), and a first input shaft (3). The sun gear (701) and the ring gear (704) are arranged concentrically, the multiple planet gears (702) are located between the sun gear (701) and the ring gear (704) and are meshed with the sun gear (701) and the ring gear (704), the planet carrier (703) is connected to the plurality of planet gears (702), and the first input shaft (3) is coaxially connected to the sun gear (701). The first motor (1) is connected to the first input shaft (3). The first clutch (13) is connected to the first input shaft (3) and is used to connect or disconnect the planet carrier (703) and the first input shaft (3). The wheel shaft (20) is transmittingly connected to the planet carrier (703). The system has a larger speed regulation range, improves transmission efficiency, and has a simple overall gearbox structure.
