Vehicle and integrated electric driving system assembly

Abstract

The invention discloses an integrated electric driving system assembly, which comprises a speed changer casing, a common end cover, a driving motor stator casing and a driving motor back end cover insequential arrangement, wherein the speed changer casing and the common end cover form a first cavity used for accommodating a speed changer; the speed changer casing and the common end cover respectively support two ends of a speed changer transmission input rotating shaft of the speed changer; the common end cover, the driving motor stator casing and the driving motor back end cover form a second cavity used for accommodating a driving motor; the common end cover and the driving motor back end cover respectively support two ends of a driving motor rotor shaft of the driving motor; the speedchanger transmission input rotating shaft and the driving motor rotor shaft are in coaxial transmission connection; the driving motor back end cover is concretely a sealing cavity for realizing a wiring function. The invention also discloses a vehicle comprising the integrated electric driving system assembly. The integrated electric driving system assembly has the advantages that the size is small; the cost is low; the reliability is high; the assembly is simple.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and its integrated electric drive system assembly. Background technique [0002] With the continuous depletion of chemical energy and the aggravation of environmental pollution, electric vehicles are increasingly used in the market. As the core component of electric vehicles, the electric drive system, the improvement of the performance of the electric drive system will affect the development of electric vehicles. [0003] At present, a common electric drive system consists of three parts: an independent drive motor, a motor controller, and a transmission. The driving motor and the motor controller are arranged separately, and the two are electrically connected through high and low voltage wiring harnesses and connectors. The drive motor and reducer are mechanically connected through bolts. The above-mentioned split electric drive system usually has a large space an...
