Following the release of the first batch of mid-shaft models that passed the fuel announcement on January 23 this year, a number of mid-shaft models have recently entered the fuel announcement. On March 20th, the Ministry of Communications publicized the table of fuel consumption for road transport vehicles (the 38th batch). Among the 18 vehicle transport models selected in the batch, 8 models were from Dongfeng Commercial Vehicle Co., Ltd., and Dongfeng Commercial Vehicle Co., Ltd. also became the largest chassis supplier among the selected vehicles.

Co., Ltd. manufactures. Among them, the largest proportion of chassis supply brands is Dongfeng commercial vehicles, a total of 8 models, followed by China FAW and SAIC Hongyan, respectively, 4 models, China National Heavy Duty Truck has 2 vehicles into the fuel announcement for publicity. In terms of driving form, there are 12 models for 6×2 models and 6 models for 4×2 models.
Among the eight Dongfeng commercial vehicle mid-axle models that entered the announcement, two were 4×2 transport models and six were 6×2 transport models. Among them, two 4×2 transportation models are produced by Dongfeng Commercial Vehicle and Tianjin Raul Industrial Co., Ltd. The two models match the engine model DDi75S350-50, the transmission model is 9JS135T-B, and the final drive ratio (drive axle) The speed ratio is 4.100 and the tire size is 315/70R22.5.
Among the six 6×2 transport models, two are produced by Dongfeng Commercial Vehicle, and the other four are produced by Dongfeng Commercial Vehicle and CIMC Vehicle (Group) Co., Ltd. The two mid-axle cars produced by Dongfeng Commercial Vehicles are matched with the ISD285 50 engine produced by Dongfeng Cummins Engine Co., Ltd., the transmission model is 9JS119TA, the final speed ratio is 4.100, and the tire specification model is 275/70R22.5. . The two vehicle transport vehicles (trains and tractors) of the ZJV5190TCL model produced in cooperation with CIMC are matched with the ISDe270 40 engine produced by Dongfeng Cummins Engine Co., Ltd., the transmission model is DF6S900, and the final speed ratio is 5.571. The tire specification model is 275/70R22.5. The vehicle model is ZJV5210TCL's two vehicle transport vehicles (train and tractor), the matching engine model is ISD300 50, the transmission model is 9JS119TA, the final reducer speed ratio is 4.100, and the tire specification model is 275/70R22.5.
Since 1998, in the field of mechanical seal work and control, we have made step-by-step efforts to overcome the limitations and difficulties of the factors that affect the stability of the sealing performance, such as the material and the shape of the sealing lip.
Since 2000, continuous improvement and optimization of polyurethane elastomer materials and research on mixing with different materials and chemical raw materials. While the physical properties are balanced, new material performances after different chemical mixtures are also deeply developed.
Regarding the mixing research and development of nitrile rubber, hydrogenated nitrile rubber, silicone rubber, fluorinated rubber and various metal powders, countless deployment tests have also successfully realized the ideal special sealing material.
In the development and improvement of polyamide (nylon resin), polytetrafluoroethylene, and phenolic resin, we also ushered in a rapid increase in the number of our European customers and a doubled increase in sales in the Asian market.
We are researching dust seals (DKBI), piston rod seals (IDI, IUH, HBY), support rings (KZT,), piston seals (OUH, SPGO) in conventional hydraulic sealing systems day after day ), anti-wear rings/anti-wear rings (WR, SPGW) and are suitable for all kinds of jib cylinders, cantilever cylinders, bucket cylinders, lifting cylinders, and power steering cylinders.
Including the research and development and iterative production of the sealing ring of the hydraulic breaker, there have also been more new breakthroughs.
Thank you very much for your attention. If you have any demand for sealing system solutions, please be sure to contact me. I will cooperate with you in an honest and professional manner.
