Delivery Of 8.6m Asiastar Buses With Zero Rear Overhang Technology + Carbon Fiber Material

Recently, a batch of Asiastar JS6869GHBEV city buses sprayed with the pattern of "Tea Mountain and Bamboo Sea" in block letters and blue background were loaded onto flatbed trucks and sent to Yongchuan, Chongqing, which is the place of the spirit of "always standing at the head of the tide and accommodating hundreds of rivers in the sea." This batch of buses has gathered the most leading technology crystallization of Chongqing Deyi and Yangzhou Asiastar: zero rear overhang technology + carbon fiber composite body. 

The zero rear overhang 1-step stepping bus comes to life

Adoption of electric drive axle allows pure electric city bus to realize the whole vehicle structural arrangement form of one-step, zero rear overhang, long wheelbase and large bearing surface, such as this time Asiastar 8.6m JS6869GHBEV pure electric city bus wheelbase can reach 5600mm, the same as the 10.5m Asiastar JS6108GHBEV wheelbase, coupled with one-step arrangement of the vehicle, the main bearing surface area between two axles is comparable to the traditional structure of 10.5m bus, and 34% higher than the previous 8.54m JS6859GHBEV wheelbase of 4200mm. The main carrying surface area of the vehicle is comparable to that of a traditional 10.5m bus, and 34% higher than the previous 8.54m JS6859GHBEV with a wheelbase of 4200mm.The maximum number of passengers on the JS6869GHBEV can be up to 85, which is not much different from that of the JS6108GHBEV, and it is catering to the declining trend of the number of passengers in bus transportation in the past two years.

Carbon Fiber Composite Body: The Perfect Combination of Lightweight and Strength

The application of carbon fiber composite material in Asiastar JS6869GHBEV city bus is a technological leap. Compared with the traditional aluminum-magnesium light alloy, carbon fiber composite material is lighter; compared with steel, it is stronger. This strategic new material, which combines structure and function, not only improves the performance of the vehicle, which is in line with the development direction of flexibility and mobility, but also brings a safer and more comfortable driving experience for passengers. The use of carbon fiber composites enables the JS6869GHBEV to achieve significant weight reduction while maintaining a strong body. The material eliminates the need for additional interior trim, reducing interior pollution and simplifying maintenance.

New quality productivity for a better life

JS6869GHBEV has a total mass of 8400kg, a rear overhang of 1060mm and an overall length of 8640mm, while JS6108GHBEV has a total mass of 11,650kg, a rear overhang of 2460mm and an overall length of 10,500mm, i.e., the vehicle's deadweight has decreased by 27%, the rear overhang has been shortened by 56% and the overall length has been shortened by 18% compared with that of JS6108GHBEV. The vehicle weight is reduced by 27%, rear overhang is shortened by 56%, and overall length is shortened by 18%. Vehicle power consumption is significantly reduced, and the service life of each assembly is lengthened. The shortened length and rear overhang not only improve the vehicle's passing performance during peak hours, but also provide more space for traveling and parking.
