Embodiment Construction
[0020] The present invention is described in detail below in conjunction with accompanying drawing:
[0021] refer to figure 1 , in order to solve the problem that the "pure needle roller bearing" scheme adopted in the prior art has difficulty in assembling the needle rollers, prone to movement interference between the needle rollers, breaking the planetary gear shaft, and partially bending or breaking the needle rollers, the present invention proposes Differentials using needle roller bearings with cages for use as power coupling devices for series-type hybrid electric vehicles. In other words, the traditional differential can be applied to hybrid electric vehicles as a power coupling device only by partially modifying the internal structure of the traditional differential.
[0022] The differential power coupling device of the present invention includes a differential case 1, a circular sleeve without holes 2, a left side gear spacer 3, a left side gear (bevel gear) 4, a pl...
