Adopting an innovative dual intermediate shaft design, the structure is compact and reasonable, not only improving space utilization but also enhancing overall stability and durability. In terms of specification parameters, this transmission can input a torque of up to 2000 N?m, capable of adapting to motors of different power levels, meeting the power transmission needs of various new energy vehicles under different operating conditions. It has 6 forward gears, and the gear ratio range has been carefully tuned, with a reasonable step difference, allowing the vehicle to easily handle frequent stops and starts in city driving, as well as sustained cruising on highways, achieving efficient power output and excellent fuel economy (electricity consumption economy). In terms of shifting performance, the transmission is equipped with advanced electronic shift actuation, with rapid shift response, extremely short power interruption time, less than 0.5 seconds, ensuring a smooth and seamless shifting process, effectively reducing the feeling of jerking, and providing drivers with a comfortable driving experience. At the same time, through the use of helical gear transmission technology, system noise during operation is significantly reduced, and the quietness is outstanding, making the vehicle’s interior environment more quiet and comfortable. From the perspective of compatible models, our transmission has strong compatibility and can be widely applied to heavy-duty new energy trucks from 10 to 30 tons and various large and medium-sized new energy buses. To meet the needs of different vehicle models, we can also provide customized services, optimizing in areas such as heat dissipation system design and software control algorithms, to match the vehicle’s unique operating conditions and performance requirements. For example, to cope with the high-load operation of vehicles in certain special working environments, we have specially enhanced the transmission’s heat dissipation function, adopting an efficient water-cooling structure, ensuring that the transmission can still operate stably under high temperature, heavy load, and other harsh conditions, extending service life.
