Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
As shown in Figure 1-3, a kind of drive mechanism of motor middle electric vehicle, including rear-wheel 1 and it is derived from 1 central axis of rear-wheel
The rear chain stay 3 for keeping motor fixed that two sides extend anteriorly out sets gradually middle studdle 4 from rear to preceding on rear chain stay 3
With front support rod 5, motor 2 is set among middle studdle 4 and front support rod 5, motor 2 includes left end cap 21 and right end cap 22,
Left engaging lug 211 is arranged in 21 two sides of left end cap, and right engaging lug 221, middle studdle 4 and front support rod is arranged in 22 two sides of right end cap
Left connector 6 is arranged in 5 left side lower section welding, and right connector 7 is arranged in lower right-hand side welding, and right 7 thickness of connector is greater than left connection
For 6 thickness of part so that the bending modulus of right connector 7 is greater than the bending modulus of left connector 6, left engaging lug 211 is bolted left company
Fitting 6, right engaging lug 221 are bolted right connector 7, when installing motor 2, tighten fastening bolt, make left connector 6 prior to the right side
Connector 7 deforms, and guarantees the accurate positionin of right engaging lug 221, active synchronization belt wheel 9 is arranged on 2 right side output shaft of motor, into
And guarantee the accurate positionin of active synchronization belt wheel 9.Passive and synchronous belt wheel 8 is set to 1 right side of rear-wheel along rear-wheel central axis, actively together
Walk belt wheel 9 and the longitudinal coplanar setting of passive and synchronous belt wheel 8.Left engaging lug 211 includes that the first left engaging lug 2111 and second is left
Engaging lug 2112, right engaging lug 221 include the first right engaging lug 2211 and the second right engaging lug 2212, the first right engaging lug 2211
It is correspondingly arranged with the first left 2111 axial direction of engaging lug, the second right engaging lug 2212 is corresponding with the second left 2112 axial direction of engaging lug to be set
It sets, in terms of 2 end of motor, the extended line in the first left engaging lug 2111 and the second left connection of engaging lug 2112 axle center is crossed to form
