自动变速箱挡位越来越多越麻烦吗?

发布日期: 2018-07-24 来源: / 点击:

自动变速箱的诞生源于人们想把驾驶者的左脚彻底解放出来并降低驾驶车辆的难度,因此自动变速箱在变速箱领域享有至高无上的地位,是全球车企争先研发的重点。随着时代的发展,自动变速箱技术逐渐成熟起来,解决了平顺和油耗的问题,越来越受到消费者喜爱。
The birth of automatic transmission is derived from people who want to completely liberate the driver's left foot and reduce the difficulty of driving. Therefore, the automatic transmission has the highest position in the gearbox, which is the focus of the global car enterprise. With the development of the times, the technology of automatic transmission has gradually matured, and the problem of smoothness and fuel consumption has been solved, which is more and more popular among consumers.
不过,传统自动变速箱对液力变矩器的依赖过大,这决定了传统自动变速器的挡位数不能过多。液力变矩器是实现自动换挡的关键部件,几乎AT和CVT都有采用。主动和被动叶轮依靠中间油液实现动力传输,减少发动机扭矩瞬间提高对变速箱造成的冲击,帮助车辆实现平稳起步。它的优点是安全稳定没有散热问题,缺点同样也很明显,相比纯机械连接的方式,由于加入了油液,传动效率比较低,导致费油。因此,近50年来汽车工程师研发重点都集中在了提高效率上,对挡位数并不关注。
However, the traditional automatic transmission is too dependent on the torque converter, which determines that the number of gears in the traditional automatic transmission can not be excessive. Hydraulic torque converter is the key component to achieve automatic shift. Almost AT and CVT are used. The active and passive impeller rely on Intermediate oil to realize the power transmission, reduce the moment of engine torque to increase the impact on the gearbox, and help the vehicle to achieve a smooth start. Its advantages are the safety and stability of the problem of no heat dissipation, the shortcomings are also very obvious, compared to the pure mechanical connection, because of the addition of oil, low transmission efficiency, resulting in oil. Therefore, in the past 50 years, the focus of R & D of Automotive Engineers has been focused on improving efficiency and ignoring the number of gears.
与此同时,在传统自动变速箱上增加挡位数十分困难。挡位的增多会让传统自动变速箱变得越来越大、越来越重,以如今的技术和工艺水平造出体积小、重量轻、成本可控的变速箱几乎是不可能的,因此传统自动变速箱的发展一直受到限制。
At the same time, it is very difficult to increase the number of gears on traditional automatic transmission. The increase of the gear will make the traditional automatic transmission become bigger and heavier. It is almost impossible to create small, light and cost controlled transmission with the technical and technological level today, so the development of the traditional automatic transmission has been limited.

为了摆脱效率问题,很多工程师独辟蹊径,开始研发与传统自动变速箱完全不同工作原理的自动变速箱。近年,ZF和爱信开始通过改变齿轮组结构设计和挡位增加,以解决传统自动变速箱的效率问题,并率先在Jeep自由光和路虎极光上搭载了9速自动变速箱。此外,通用和福特在2013年宣布联合研发9速和10速自动变速箱,大众集团宣布10速双离合变速箱开发工作已经开始,现代汽车成功研发的10速变速箱,将于2014年投入到量产中。未来,自动变速箱的挡位会越来越多。
To get rid of the problem of efficiency, many engineers have developed a new type of automatic transmission, which is completely different from the traditional automatic transmission. In recent years, ZF and asin began to increase the design and gear of the gear group to solve the problem of the efficiency of the traditional automatic transmission and take the lead in carrying 9 speed automatic transmission on the Jeep free light and the Land Rover aurora. In addition, in 2013, general and Ford announced the joint development of 9 and 10 speed automatic transmission, the Volkswagen Group announced that the 10 speed double clutch transmission has begun, and the 10 speed gearbox developed by modern cars will be put into production in 2014. In the future, there will be more and more gears for automatic transmission.
越来越先进的技术让变速箱增加挡位不再是难题。较近几年变速箱挡位越来越多,但远没达到安全稳定可靠的水平。一些车型着急上马挡位数更多的变速箱,其实是想通过挡位数塑造车辆的先进性,博个技术噱头。目前仅有几个小众品牌车型搭载了多挡位自动变速箱。
With more and more advanced technology, increasing gear shift is no longer a problem. In recent years, gearboxes are more and more blocked, but they are far from safe, stable and reliable. Some models are more anxious to get more gear boxes. Actually, they want to shape the advanced nature of the vehicles through the number of gears, and make a technical gimmick. At present, only a few minority brand models are equipped with multi shift automatic transmission.
多挡位变速箱会随着规模效应的影响扩大,逐步降低生产成本、维修成本,但更大的问题还在于更复杂的结构。从汽车机械工程的角度来看,变速箱拥有更多挡数就会让每一个齿轮同时搭配更多传动零部件,这就意味着制造更复杂,结构更精密,体积越大。这样的变速箱必然会对消费者驾驶习惯提出更高的要求,因为它需要十分挑剔的照顾。
The multi shift gearbox will expand with the influence of scale effect and gradually reduce production cost and maintenance cost, but the bigger problem is more complicated structure. From the point of view of the mechanical engineering of the car, the more gear with the gearbox will allow each gear to match more transmission parts at the same time, which means that the manufacturing is more complex, more precise, and the larger the volume. Such a gearbox is bound to put a higher demand on consumer driving habits, because it needs very picky care.
