A centrally-mounted motor structure of an electric motorcycle comprises a frame, a centrally-mounted motor is arranged on the frame, the output end of the centrally-mounted motor is connected with a reduction gearbox, a primary reduction bevel gear is arranged on the reduction gearbox, a driven bevel gear is meshed with the primary reduction bevel gear, and a final-stage driving gear is meshed with the driven bevel gear. The tail-stage driving gear is meshed with a tail-stage driven gear, the tail-stage driven gear is connected with an output shaft, the output shaft is connected with a driving chain wheel, the driving chain wheel is connected with a tail-stage chain wheel, the frame is provided with a left bottom fork and a right bottom fork, and the center of the left bottom fork and the center of the right bottom fork coincide with the center of the output shaft. The electric bicycle has the advantages that the middle motor is of a longitudinal structure, the center of gravity of the whole bicycle is stable, riding comfort is good, stability is high, swing of the chain can be reduced, the service life of the chain can be prolonged, a larger transmission ratio can be achieved through two transmission modes, output torque can be increased easily, and the whole structure is high in strength and reliable in movement.

    一种电动摩托车的中置电机结构,包括车架,车架上设置有中置电机,中置电机的输出端连接有减速箱,减速箱上有初级减速锥齿轮,初级减速锥齿轮上啮合有从动锥齿轮,从动锥齿轮上啮合有末级主动齿轮,末级主动齿轮上啮合有末级从动齿轮,末级从动齿轮上连接有输出轴,输出轴上连接有主动链轮,主动链轮上连接有末级链轮,车架上设置有左平叉、右平叉,有左平叉、右平叉的中心处与输出轴的中心处重合。本发明有益的效果是:中置电机采用纵置结构,整车的重心稳定,骑行舒适性好,稳定性强,能够减少链条摆动,增加链条的使用寿命,通过两家传动能够达到更大的传动比,有利于输出扭矩的增大,整个结构强度高,运动可靠。
