摘要： A human power conversion system incorporates two or more electric machines to aid in the powering of a vehicle through energy conversion. A first electric machine is coupled with the human powered input and acts as a generator when a human power input is not sufficient to produce electrical power that is provided to a second electric machine that propels the vehicle. The vehicle may be a bicycle and the first electric machine may be coupled to the crank. A bi-coupled electric machine including the first and second electric machines with a common rotor or stator may be employed and coupled to the crank and/or the driven wheel. Power produced by the first electric machine may be provided directly to the second machine or may be stored in a battery and used to propel the vehicle or power other electronic components.

摘要： A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.

摘要： In a motor power transmission device (30), wherein rotational power of an electric motor (40) is input to a sun gear (51) of a planetary speed reducer (50), and then the rotation of the sun gear (51) is converted to rotation of a planetary carrier (55), and wherein the planetary carrier (55) rotatably supports planetary gears (61, 62) and converts revolving motion of the planetary gears (61, 62) into rotating motion, and the rotation of the planetary carrier (55) is then output to an output shaft (15), a torque limiter mechanism (57) is interposed between the planetary carrier (55) and the output shaft (15). Thus, even if excessive back torque is input to the output shaft, transmission of the back torque to the speed reducer is blocked to protect the speed reducer.

摘要： A lubrication system of a power assembly of an electric scooter includes a case duct and a bearing seat duct formed in a case of the power assembly, and a driven gear shaft duct formed in a driven gear shaft of a driven gear. Lubricant flows to the case duct, the driven gear shaft duct, a driven gear bearing seat in the case, the bearing seat duct, a driving bearing seat in the case in sequence. The lubrication system has a short flowing distance of the lubricant to enhance the effects of lubrication and reducing temperature.

摘要： The invention relates to a drive unit for fitting or retrofitting a two-wheeled vehicle (1), preferably a bicycle, having an electric motor which is designed as a disc motor (10), comprising a rotor disc (11) having permanent magnets (12) and an annular stator (13) with windings, which generate an electrical alternating field for driving the rotor disc (11), wherein the rotor disc (11) can be fastened non-rotatably to a receptacle (6) on the front or rear wheel of the two-wheeled vehicle (1) and the annular stator (13) can be fastened to a frame part (4, 5) of the two-wheeled vehicle (1). For tool-free dismantling the annular stator (13) can be unfolded in the circumferential direction and can be removed or pulled off from the rotor disc (11).

摘要： A human-powered vehicle control device includes an electronic controller that controls a motor used to assist in propulsion of a human-powered vehicle. The electronic controller is selectively settable to a first control state that controls the motor in accordance with human drive force and a second control state that controls the motor in accordance with human drive force so that a ratio of an output of the motor to the human drive force is greater than that of the first control state. In the first control state, the electronic controller controls the motor so that a response speed of the motor with respect to a change in the human drive force is equal to a first response speed. In the second control state, the electronic controller controls the motor so that the response speed is equal to a second response speed that is slower than the first response speed.

摘要： A Light Electric Vehicle (LEV) 10, 20 includes two motors 24a, 24b and independent control of each motor. The two motors have different drive ratios (for example, gearing 26 or pulley/sprocket 28 ratios) or different efficiency versus RPM curves and are controlled to provide efficient operation over a wider speed range than possible with a single motor or two motors having the same efficiency at any given vehicle speed.
