几万块到上百万的车型都配双离合 大众双离合究竟是好是坏


大众双离合器,有人说节油换挡速度快,是变速箱的杰出代表,有人说它令人沮丧且容易折断,是变速箱中最差的选择。面对这样的争议,大众汽车集团在推动双离合器变速箱方面仍然非常强大。但是,从数万美元到达数十万Q5,甚至数百万保时捷都使用双离合器,大众汽车集团的双离合器是好还是坏?

这很被动。丰田有自己的控股爱信做AT变速箱,通用汽车有自己的子公司做AT变速箱,日产有自己的控制JATCO做AT和CVT变速箱,现代也有自己的Powertech变速箱生产公司。

因此大众汽车决心开发自己的变速箱技术,双离合器只是其选择的突破。虽然开始时的双离合器确实存在很多耐久性问题。然而,无论成本如何,大众汽车集团都在不断改进双离合器的问题。双离合器变速箱适用于所有型号,质量尽可能平铺。此外,使用自己的变速箱,当然会更便宜,因此车辆的利润会更高。

大众汽车的双离合器并不完全一样,它真的应该是同一句话,一分钱。我们来谈谈几种不同的DSG。

干式7速双离合器的最大负载能力为250 Nm,主要用于Sagitar Golf等中型排量车型。传动效率高,因此燃油经济性非常好,成本也最便宜。

然而,这个变速箱在大面积上存在问题,而且它也出现在CCTV 315上。尽管现在基本上已经解决了,但仍存在潜在的风险。容易过热,长时间造成损坏,低速蠕变,不适合城市使用。

Wet 6-speed dual clutch, the maximum load capacity of 350 Nm, Tiguan, Yu Yue, Audi Q3 and other use of this gearbox. Because it is a German original gearbox, plus the wet structure, compared to the DQ200 reliability is much higher, the popular power with 1.4T + DQ250 is a relatively reliable choice.

However, this fuel economy has declined compared to the dry dual clutch.

Wet 7-speed dual clutch, the maximum load capacity of 420 Nm, mainly used in Lingdu speed and other models. This gearbox is based on the DQ500.

This simplified version of the DQ500 is mainly intended to replace the imported DQ250 and is a special offer for China. This gearbox has no major problems, but its stability and performance are not as good as the DQ250, only for the two-wheel drive model.

Wet 7-speed dual clutch, the structure and DQ380 are the same, Volkswagen started to push, a series of upgrades compared to DQ380, Audi S3 and other countries will replace this gearbox after 6.

Wet 7-speed dual clutch with a maximum load capacity of 600 Nm. Like the DQ380, it is produced at the Tianjin DSG Transmission Factory. It is mainly used in Audi TT RS, Touran, Tiguan L and so on.

Finally, there are PDK gearboxes used in the Porsche series, each of which is two or three hundred thousand, which represents the highest technology of double clutch. Both shifting speed and durability are benchmarks, and stability also hangs an AT. But this gearbox is not comfortable, after all, this setback is a performance of sports. The reason why it can't be popularized is because it is expensive.

Which double clutch do you like, leave a message and tell me.
