Embodiment Construction
[0029] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0030] Such as figure 1 As shown, a center-mounted wheel core-driven electric drive automatic transmission system mainly includes a power input mechanism, a driving wheel 2, a shifting transmission mechanism arranged on the outer intermediate shaft 3, and the outer intermediate shaft through a chain transmission assembly. 3 connected to the in-wheel intermediate shaft 16 and the deceleration output mechanism arranged on the wheel installation shaft 17, the power input mechanism sequentially transmits power to the The deceleration output mechanism drives the drive wheel 2 to rotate by the deceleration output mechanism.
[0031] The shifting transmission mechanism includes a one-sided synchronizer 4, an overrunning clutch 15 and a reduction assembly. The one-side synchronizer 4, the overrunning clutch 15 and the first-stage deceleration driving gear 6 of the r...
