Embodiment 1
[0028] Such as figure 1 Shown is Embodiment 1 of the present invention. In this embodiment, the integrated electric drive powertrain includes a motor and a gearbox (usually a reducer), and the output shaft of the motor is integrally made with the input shaft of the gearbox to form a power The main shaft 18 of assembly is provided with parking gear 5 in the gearbox, and parking gear 5 is fixedly installed on the main shaft, promptly is installed on the main shaft 18.
[0029] Affected by the torque transmission of the gearbox (reducer), the parking torque on the main shaft is small, and the axial dimension of the parking gear 5 can be designed to be relatively small, thereby reducing the axial dimension of the powertrain. The weight of the 5 is reduced, and so is the weight of the powertrain.
[0030] The motor can be a permanent magnet motor or an excitation motor, including the rotor 17 and the stator 2 . The rotor 17 includes a rotating shaft therein, which is also part of...
Embodiment 2
[0052] This embodiment is improved on the basis of embodiment 1. In embodiment 2 of the present invention, the third gear 11 is integrally formed with the intermediate shaft 10. This design can further simplify the structure of the powertrain.
[0053] Other structures of the integrated electric drive powertrain in Embodiment 2 of the present invention are the same as those in Embodiment 1, and will not be described again here.
