Geely Automobile exposure of the latest power-blog the PRO version of the four-wheel drive models, technology deployment, and naming the PRO Bo intelligent four-wheel drive version. Power system 1.5TD + 7DCT + BSG high-performance power, significantly improved in terms of fuel economy, overall saving rate also increased from 12 to 15 percentage percentage of industry, hundred kilometers only 6.4L.
wheel drive vehicle equipped with a fifth generation BorgWarner electro-hydraulic four-wheel drive system. Bi Boge Warner to domestic brands NexTrac electromagnetic systems have a certain upgrade. The system eliminates the conventional accumulators, with industry-leading electric centrifugal pump, and thus lighter and more compact structure, reducing the overall weight percentage of 35, the mechanical construction is also effective in reducing the weight of the fuel.
The four-wheel drive vehicle will be traveling state, the control unit issues a command, by increasing or reducing the pressure multi-plate clutch clamping force to be distributed around power. Under normal circumstances, the system will most power distribution to the front axle (drive close to the front), thereby saving fuel. Such as when the front wheel slip occurs, the system increases the working oil pressure system, by pressing the clutch piston, transmitting power to the rear axle. The front-wheel slip occurs when the front and rear wheel torque distribution ratio up to a maximum of 50:50, so as to effectively enhance the resistance by the vehicle, of the turnaround.
