Abstract

The invention relates to the field of vehicles, and discloses a vehicle and an electric drive system.The drive system comprises a first drive motor (1), a second drive motor (2) and a transmission mechanism in transmission connection with a half shaft (8), and the transmission mechanism is in transmission connection with a power output shaft of the first drive motor (1) through a first transmission path provided with a clutch (4) and a first brake (5); and a second transmission path provided with a second brake (6) is in transmission connection with a power output shaft of the second driving motor (2). According to the electric drive system, the first drive motor and / or the second drive motor can be switched to output the drive power by changing the braking states of the first brake and the second brake, smooth switching of different gears is achieved through the clutch in the switching process, and therefore the pause feeling caused by gear meshing state changes is avoided; and the gear shifting experience of the user is improved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an electric drive system for vehicles. On this basis, the invention also relates to a vehicle with the electric drive system. Background technique [0002] In a vehicle, the power generated by the driving device is usually transmitted to the half shaft and the wheels by a transmission mechanism including a transmission, so that the vehicle can be driven at variable speeds by changing the transmission ratio of the transmission. Typically, the transmission uses a synchronizer shift mechanism to realize gear shifting, which has problems such as long shifting time and large shifting impact, resulting in uneven shifting, and users have obvious frustration during the shifting process. Contents of the invention [0003] The purpose of the present invention is to overcome the problem of uneven gear shifting in the prior art, and provide an electric drive system, which can effectively improve t...
