Problems solved by technology

So configured that the total volume / dimensions of the transmission, motor and inverter joined / connected together are very large and the interconnections required are very expensive making the overall cost of the electric drive system high
In addition, the space inside the car is limited and limited. The existing configuration of the motor, inverter and transmission occupies a large space in the car, which brings difficulties to the overall layout of the car, and the overall cost is relatively high
Higher cost electric drive systems uncompetitive

Abstract

The invention provides an integrated power driving system for a vehicle, which comprises a motor (1), a transmission (2) arranged at the output end of the motor (1), and an inverter (3) arranged at the other end, opposite to the output end, of the motor (1), wherein the motor comprises a motor shell (11), a front end cover, a rear end cover and a stator assembly (10) and a rotor assembly (14) accommodated inside the motor shell (11); the transmission (2) is provided with a transmission shell, the transmission shell comprises a transmission semi shell (12) close to the motor (1), and the transmission semi shell (12) is formed to be the front end cover suitable for the motor (1); the inverter (3) comprises an inverter shell (13), a power module (31) and an inverter end cover (32), and the inverter shell (13) is formed to be the rear end cover suitable for the motor (1); and the inverter shell (13) and the transmission semi shell (12) are arranged on the motor shell (11) via a fastener. The power driving system is compact in structure and low in manufacturing cost.

Description

technical field [0001] The present invention relates to the field of motor vehicles, and in particular to an integrated electric drive system for motor vehicles. Background technique [0002] With the development of automotive technology, especially the continuous attention to electric vehicles (ECV), hybrid electric vehicles (HEV) and fuel cell vehicles (FCEV) in recent years, the corresponding research and development are also deepening. [0003] Electric drive systems for vehicles of the above types typically include an electric motor, an inverter, and a transmission. Currently, the three parts of the motor, inverter and transmission are manufactured separately, the motor and transmission are joined together by fasteners, and the motor and inverter are connected together using polyphase cables. This configuration makes the overall volume / size of the transmission, motor and inverter coupled / connected together very large, and the expense required for the internal connectio...
