What are the differences between DQ381 and DL382?
1 Answers
Here are the differences between DQ381 and DL382: 1. DQ381 improves transmission efficiency. In addition to using higher-viscosity ATF oil and optimizing the friction of sealing rings and bearings, the clutch module and the hydraulic system of the oil pump have also been modified. The spiral type is changed to a diaphragm type. In terms of hydraulics, an additional electric oil pump connected to the CAN bus is added, which is regulated through valves. 2. DL382 is a longitudinally mounted transmission, initially designed to replace VL381, and can support engine torque up to 400Nm. 3. DL382 optimizes the output shaft to the front axle. This shaft does not need to run outside the transmission housing but is directly borne by the output shaft of the transmission. This transmission employs many measures to increase efficiency. The gearbox and clutch hydraulic parts are divided into two lubrication zones. 4. The dual clutch of DL382 uses a wave-shaped release spring, which helps reduce the drag torque of the clutch (when disengaged). The reduction can be up to 40%, lowering CO2 emissions by 0.5g/100km under NEDC conditions.
