As the main representative of the independent brand, the acquisition of the DSI transmission in Australia and Sweden old car company enterprises after Volvo, cobolli gigli seems to become more foot bottom spirit, and the guangzhou motor show, they brought the loading is already 6 AT power systems.
This machine 6 speed AT the main structure still used the transmission is our familiar hydraulic torque converter + the structure of the planetary gear set, with multiple electric lock up the clutch, realize the transmission ratio of the change of different gears, six gears in the ratio between 3.536 and 0.677 changes. As in the exhaust platform model in use, it sets the structure of the transmission is compact, axial length is 751 mm, and can completely in the compact class models use.
Hydraulic torque converter is equivalent to manual transmission of the clutch, the transmission power, ease with the impact.
From this Angle, we can see AT the transmission of key part, planetary gear set.
Giovanni cobolli gigli on this 6 AT the transmission, apply to exhaust the engine precursor or four-wheel drive vehicles, be worth what carry is, this one 6 speed automatic transmission of maximum input torque to reach 400 cattle · m, want to know common 3.0 displacement naturally aspirated car DVD palyer
engines (such as BMW 330 I the N52 straight six engine and Toyota RuiZhi V6 engine 3.0) maximum output torque in 300 cattle · m fluctuation, so this one transmission appear, means a quite long time period in the future, cobolli gigli car and SUV products don't have to research more big torque to bear ability automatic transmission, shorten the development cycle, and reduce the cost.
The back section of the white transmission for control of the block a switch in the rotary piston box, its design and manufacturing requirements are quite high.
And in the booth, and the 6 AT the match is the transmission cobolli gigli research 2.4 displacement JL result 4 g24i naturally aspirated engines, the maximum power 112 kw, can turn in 4000 when the maximum torque output 210 cattle · m, AT the same time in the DVVT continuous variable valve timing with the car cameras
help of technology, its low speed torque very well, only in 2000 when turn can reach 186 cattle · m, very suitable for home use.
Despite this show of 2.4 DVVT engine, giovanni cobolli gigli has in the global hawk GC7 to 1.8 DVVT engine and six AT the combination of transmission, it can be said that this type of transmission can match the dynamic system of optional room or larger.
Although a lot of people to this one comes from the DSI technology 6 AT also skeptical, but from the actual performance, it should be said that it has been doing rather well, it will not only bring more dense of transmission ratio, the more smooth dynamic performance, also still can make vehicles more fuel economy with performance, more important is, it let consumers with more affordable price to buy equipment 6 speed automatic transmission family car, this is clearly what AD than practical.
