The invention discloses a fan electronic control driving device for an electric road sweeper. The fan electronic control driving device comprises a fan assembly, the fan assembly comprises a fan support, a permanent magnet motor and a volute are fixed to the fan support, an output shaft of the permanent magnet motor extends into the volute to be connected with an impeller assembly, a flow guidingopening is fixed to the volute, the permanent magnet motor is electrically connected with a motor controller through a high-voltage wiring harness, the motor controller is connected with a high-voltage power supply through a high-voltage wiring harness, a low-voltage signal wiring harness is further connected between the motor controller and the permanent magnet motor, and the motor controller isfurther connected with a whole machine controller through the low-voltage signal wiring harness. Compared with a traditional fan transmission structure, the fan electronic control driving device for the electric road sweeper is simpler and higher in control efficiency, effective energy saving of a motor can be achieved, the operation efficiency of the road sweeper is effectively ensured, the electric quantity is saved, and the operation time is prolonged.
Description
technical field [0001] The invention relates to the field of electric road sweepers, in particular to an electric fan electric control driving device for electric road sweepers. Background technique [0002] At present, due to the country's emphasis on the new energy vehicle industry, a large number of pure electric sanitation vehicles are used in road cleaning and cleaning operations. Pure electric road sweepers are widely used because of their environmental protection and energy saving features. The driving mode of the fan, the core component of the existing electric road sweeper, generally adopts belt drive, and the fan itself is equipped with a bearing seat. This traditional transmission structure is relatively complex, with high frequency of failures, high requirements for fan bearing housings, and prone to bearing ablation. Because of the belt drive, the transmission efficiency will be reduced, and the power consumption will be higher. Contents of the invention [...
