Title:
MULTI-GEAR EV POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/153150
Kind Code:
A1
Abstract:
Provided is a multi-gear EV power device. The device comprises a gear speed change device mainly composed of a planetary support (10), a power center wheel shaft (20), an outer planet wheel (60) and an inner planet wheel (70), a first motor set connected with the head end of the power center wheel shaft (20), a second motor set connected with the tail end of the planetary support (10) and a power output device connected with a power output shaft sleeve (40) formed on an outer sun wheel (30), wherein, the planetary support (10) is internally provided with an inner sun wheel (50) in the tail end and is internally provided with an outer sun wheel (30) in the head end, the power center wheel shaft (20) is arranged in the planetary support (10) in a penetrating mode and is connected with the inner sun wheel (50), the outer planet wheel (60) is arranged on the planetary support (10) and is meshed with the outer sun wheel (30) at the head end, and the inner planet wheel (70) is arranged in the planetary support (10) and is meshed with the inner sun wheel (50) and the tail end of the outer planet wheel (60) at the same time. According to the multi-gear EV power device, power input is carried out by utilizing the two configured motor sets, and the motor sets can play roles of a power motor, a gear shifting motor and even a power generation motor according to the logic control requirement, so that the maximization of application of motor resources is facilitated, and moreover, diversity of power output modes is greatly enriched.
