Problems solved by technology

[0002] The driving devices of existing two-wheeled electric vehicles (electric bicycles) all rely on a single motor to directly drive the center shaft of the rear wheel. When the output power of the motor is constant, there are problems such as small starting torque and low motor efficiency when starting, and there is a problem of creeping Insufficient power when climbing a slope, and low motor efficiency when climbing a slope lead to high current operation, which shortens the mileage of the vehicle, causes damage to the battery, and shortens battery life, etc.

Embodiment Construction

[0009] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0010] Such as figure 1 with figure 2 As shown, the driving device in the present invention is installed on the vehicle frame (not shown) of the rear wheel 15 of the two-wheeled electric vehicle, and is used to drive the central axis 9 fixedly connected with the rear wheel 15 . The driving device among the present invention includes main motor 2, auxiliary motor 1, two pinion gears 3, drive gear 6 and one-way bearing 8 and one-way device (not shown in the figure).

[0011] The rear wheel 15 of the two-wheel electric vehicle is fixedly connected with the central shaft 9, and is pivotally connected with the vehicle frame through the bearing 18 simultaneously. The two ends of the central axis 9 and the vehicle frame are pivotally connected to extend outwards, and one end is sleeved with a sleeve 16 for separating the rear wheel 15 and the ve...

Abstract

A driver unit for driving back wheel of an electric two-wheel vehicle is composed of a primary motor with output axle and gear, a secondary motor with output axle and gear, a drive gear engaged with said gears of primary and secondary motors, and a unidirectional bearing for coupling said drive gear with the axle of back wheel. It can shorten the high-current working time of electric accumulator.

Description

technical field [0001] The invention relates to a two-wheel electric vehicle, more specifically, to a driving device for the two-wheel electric vehicle. Background technique [0002] The driving devices of existing two-wheeled electric vehicles (electric bicycles) all rely on a single motor to directly drive the center shaft of the rear wheel. When the output power of the motor is constant, there are problems of small starting torque and low motor efficiency when starting, and there is a problem of creeping Insufficient power when climbing a slope, and low motor efficiency when climbing a slope lead to high current operation, which shortens the mileage of the vehicle, causes damage to the battery, and shortens the battery life. Contents of the invention [0003] The object of the present invention is to provide a driving device for a two-wheeled electric vehicle, which can overcome the problems existing in the existing two-wheeled electric vehicle. [0004] A two-wheeled ...
