In June of this year, China Automotive Evaluation Institute hosted the world's top ten transmission selection activities. The results of the recent selection were formally announced. Great Wall, Volkswagen, Mercedes-Benz, SAIC, Honda, General Motors, Buick and other vehicle transmission assemblies all ranked on the list.
Before and after the ranking, the list of products are: Great Wall Motor 7DCT transmission, Volkswagen DS380 and DQ500 dual clutch automatic transmission, Mercedes-Benz 9-speed automatic transmission (9G-TRONIC), SAIC EDU intelligent electric drive transmission, mining EF 9-speed automatic transmission, Honda ECVT transmission, Sunray Drive 2nd generation front-drive 8-speed automatic transmission (start-stop), Universal 9-speed Hydra-Matic intelligent transmission, EREV extended range hybrid system.
(Great Wall Motor 7DCT Transmission)
The domestic research on the three major parts lags far behind overseas car companies, and the development of the gearbox is not the first. As early as 2011, BYD Swift has been equipped with a self-developed dry dual clutch gearbox 6DT25. , And in the later launch of the s7 took the lead in carrying a self-developed wet dual clutch gearbox 6DT35. Great Wall Self-developed 7DCT450 Wet Dual Clutch Gearbox is not too bad in terms of parameters. The maximum torque of 450 Nm·m is higher than most of its own brands nowadays, but no speed limit is also displayed on the side of the Great Wall 2.0. t The engine's low torque is really weak, and it can only rely on the deceleration and increase the torque to ensure a certain torque output. Does this 7DCT gearbox have reached the top level of the current joint venture brand? Or look at the actual application.
According to the organizers, the selection criteria can be attributed to three points: gearboxes with great influence on the industry, market and consumers, high attention and importance, and outstanding performance in the comprehensive evaluation of “advanced gearboxesâ€. Outstanding performance in the same type of opponents; transmission with special performance and special performance.
Roll Crusher Applications
Roll Crushers are simple in design and construction, long-lasting, economical, and versatile. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or Cone Crusher. Product size is much more consistent. Both oversized pieces and fined are minimized. Wet, sticky materials are more easily handled.
The rolls act as flywheels, contributing to smooth operation and efficient use of power. Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed. Adjustments are simple. Internal parts are readily accessible.
Typical feed materials for Roll Crushers include: bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells, and sewer sludge clinker. Single Roll Crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.
