Abstract

The invention discloses a two-stage transmission middle motor of a moped, and relates to the field of motors. An existing middle motor is generally of a parallel expansion type structure, and engagement and disengagement efficiency, the transmission effect and moment all have room for improvement. The two-stage transmission middle motor comprises a shell, a motor assembly, a transmission assembly,a centre shaft, a controller, a one-way clutch, a moment sensor and an auxiliary power output disc. The transmission assembly is a two-stage gear reduction system. A first-stage transmission large gear of the transmission assembly is engaged with a transmission gear of a rotor shaft, the first-stage transmission large gear is fixed to an axle of a second-stage transmission small gear, and the second-stage transmission small gear is engaged with a driven large gear. The driven large gear cooperates with a shaft ring of the one-way clutch. The one-way clutch, the deformation generating part ofthe moment sensor and the centre shaft are sequentially in engaged connection through gears. The moment sensor is electrically connected with the controller. The overall structure is simple, inductionis sensitive, the power output effect is good, the engagement and disengagement efficiency is high, and the assistance effect is effectively improved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a mid-mounted motor of a two-stage transmission power-assisted vehicle. Background technique [0002] Mopeds, also known as power-assisted electric bicycles, provide the kinetic energy needed for bicycles to travel by assisting manpower with electric power. In my country, electric vehicles still occupy the main market, and most of them adopt hub-type drive. The hub-type drive is to place the motor on the front or rear wheel of the electric vehicle body, causing the center of gravity of the vehicle to be front or rear. Fits the way people ride. Moreover, the installation method of the hub motor also increases the difficulty of maintenance and increases the cost of use. [0003] Existing mid-mounted motors usually have a parallel-expandable structure, and their composition usually includes a casing, a motor body, a gear reduction mechanism, a clutch, a central shaft, and a crankshaft as an a...
