As a Chinese own vehicle brand, Geely Auto seems to be more confidence after acquired Australia DSI transmission company and Sweden Volvo Auto, they now brings the brand-new 6AT power system – JLδ-4G24
The Geely JLδ-4G24 6AT system originate from DSI technology
6-speed AT transmission main structure is still using the familiar torque converter + the structure of the planetary gear set , supplemented by multiple electronic control lock-up clutch to achieve different gear transmission ratio changes , six gear speed ratio change between 3.536 to 0.677 . In the transverse platform models , this transmission structure is quite compact, the axial length of 751mm , and can use in the compact class models .
The torque converter is equivalent to the manual transmission clutch from the transmission of power to ease the impact of use
Lock-up clutch control is the means of transmission gear switch
From this perspective, we can see one of the core components of the AT transmission , the planetary gear set
Geely 6AT transmission applies to the transverse engine precursor or four – wheel – drive models , it is worth mentioning that this six -speed automatic transmission input torque of 400 Nm , to know the common 3.0 maximum output torque of the displacement naturally aspirated engine ( such as the BMW 330i ‘s N52 straight-six engine and Toyota Reiz 3.0V6 engine ) is also 300 Nm up and down , so the transmission , which means for a long time, the Geely cars and SUV products no longer need to develop greater torque bearing capacity of the automatic transmission , which greatly shortens the development cycle , but also reduces costs .
Gleagle GX7 is expected to fit up such 6-speed automatic transmission
Transmission on the back of the white part is the slide valve control gear switch box design and anufacturing require high
Specifications:
In the booth, and this 6AT transmission matches the Geely study of 2.4 displacement JLδ – 4G24 naturally aspirated engine , maximum power of 112 kilowatts at 4000 rpm and maximum torque of 210 cattle · m , while DVVT continuously variable valve timing technology to help its low-speed torque performance is also very good , only when the 2000 rpm to 186 Nm , it is suitable for domestic use . In addition to the Folio impressions 2.4DVVT engine , Geely Global Hawk GC7 achieve a combination of 1.8DVVT engine and 6AT transmission can be said that the optional room for this transmission can match the power system is still relatively large .
The 1.8DVVT engine and 6AT power system which has already been installed on Gleagle GC7
Summary : Although many people were both derived from the DSI technology 6AT also skeptical , but from the point of view of actual performance , it should be said to have done quite well , it will not only lead to more dense the transmission ratio , more smooth dynamic performance , while vehicles with better fuel economy performance , more importantly, it allows the consumer to buy a 6-speed automatic transmission family cars more affordable price , which is obviously what publicity actually
