Rain and snow are still falling, but distributed driven buses are not afraid at all..
February 29, 2024
Since the Spring Festival，Frequent rainfall and snowfall have brought a lot of impact on public transport operations around the country.。According to the weather forecast of the Central Meteorological Observatory，In the next few days，There are still many areas in the country covered by rain, snow and low temperature.，The traffic environment is still complex.。
“Take the snow as the order，Bus people have already formed a habit.。”Linfen Public Transport Co Ltd（Hereinafter referred to as“Bus in Linfen”）Ren Weixing, manager of the second company, said.，As one of the basic services of urban people's livelihood.，Urban public transport is the preferred means of transportation and guarantee for people to travel in rainy and snowy weather.。“In the past, whenever there was a snowy day,，We all have to make arrangements in advance.，Survey the operation line in advance、Anticipate in advance、Act in advance，And put forward strict norms for driving behavior.，Make every effort to ensure the safety of passengers”，And this year，Because of the application of distributed wheel drive bus，“Our Driver Feedback：Vehicles run more steadily on the road.、Safer。”Disc hub power，Zan 7 is compared with the centralized drive commonly used in pure electric buses at present.，Bus adopting distributed wheel-side driving，Each motor corresponds to a driving wheel.，With motor control system，The driving force and the braking force of each wheel can be flexibly distributed and controlled relatively independently，Provide higher quality actuator output feedback for Vehicle dynamics control，O as to realize the accurate control of the Vehicle motion.。
Adopted by Linfen Bus“Subway bus”Take the bus type as an example.，“Light weight、Small size、High efficiency”Axial flux motor with disc hub power self-developed electronic differential control system，The vehicle can be driven under the condition that the single-wheel adhesion force is close to 0，Still available at 12%A smooth start on the ramp.，Make a quick turn in vehicles、Under extreme conditions such as continuous winding，It can also fully guarantee the stability of the body.。
“The effect of this system on wet and slippery ice and snow pavement is very obvious.”Wang Xingqiang, manager of Linfen Bus Company 3, said.，Since the beginning of winter，Continuous snowfall in Linfen City，Continuous snowfall from February 19 to 23，The snow depth of some lines is close to 10 centimeters.，“The snow on the road became very slippery after repeated rolling.，Driving a vehicle requires great care.”，But the application“Subway bus”Bus with distributed wheel drive solution，The adaptability to this kind of wet and slippery pavement is obviously better.，Not only does the vehicle run very smoothly,，There was no slippage，And it's getting started、Climb、Turn the corner、Braking and other working conditions，“The 8-meter cart is more stable on the snow than the 6-meter car.、Even better”。
On the other hand，After adopting distributed wheel-side drive，The differential is no longer required、Transmission、A series of devices such as transmission shaft，It can be lightweight，Chassis space can also be saved，At the same time, the space inside the car is further released.，Enhance the flexible transport capacity of vehicles，——“In snowy days, many passengers will give up other modes of transportation and take buses instead.，The demand for transport capacity has increased significantly.，Adopt‘Subway bus’The 8-meter bus can reach the passenger carrying capacity of the ordinary 10-meter bus.，This also effectively alleviates our scheduling pressure to a certain extent.。”
And in day-to-day operations,，One-step boarding、All-flat low-floor“Subway bus”Buses are also widely praised by passengers.。“We're here‘Respect and love the elderly’This kind of vehicle is used on all the theme bus lines.，It has more space.、The aisles are wider，Whether it's a wheelchair、A buggy、The shopping cart can be passed easily.，And the interior of the carriage is flat from front to back.，It is very suitable for the travel needs of the elderly.，So the response from the passengers has been very good.。”
