specific Embodiment 1
[0048] Specific embodiment 1 of the two-speed power system of the present invention: In this embodiment, the two-speed power system in the present invention is introduced by taking the driving device as a hybrid drive device as an example, as figure 1 As shown, the two-speed powertrain is used to send power to the axles to propel the vehicle.
[0049] Specifically, the two-speed power system includes a driving device and a two-speed shifting mechanism 1. The two-speed shifting mechanism 1 performs power transmission between the driving device and the axle 2, drives the wheels 3 at both ends of the axle 2 to rotate, and realizes shifting. file function.
[0050] Wherein, the drive device includes a first power unit 4 and a second power unit, the first power unit 4 further includes an engine 5 and a first motor 6 , and the second power unit is composed of a second motor 7 . The first motor 6 and the second motor 7 are ISG motors integrated with starting and generating.
