ANTONOV END CO-OPERATION DEAL WITH GEELY !!!!!!!!!!!!
LONDON (Thomson Financial) - Antonov PLC said it will not go ahead with its co-operation with Geely as the automobile components company did not fulfil its financial and other obligations under the contract.
The automatic transmission concept developer said the initial production licence lapsed in September 2007 and that the cessation of the deal had no impact on its first half results.
Antonov said: "This decision has no impact on the company's published results for the first half of 2007 as prudently provision had already been made for the unpaid amounts from Geely."
Antonov自动变速器特别的地方在哪里呢？基于新的动力学和制造技巧。这就是秘密。我想吉利有经验的工程师已经研究过这个了。

项目目标：
Antonov小组认为新一代变速器必须满足以下要求：
小型化、重量轻、高效、低成本；
采用简单控制，在改变变数币上只有两种因素在起作用；
在每个档位比率上可以自由调控。
很明显主要任务就是开发一种新概念变速器而避免目前的自动变速器发展过程仍未解决的问题。

概念和设计：
一种基于新的动力学和工艺技术的第五代6速Antonov变速器产生了。这种新发明的概念被专利所保护。行星齿轮动力学结构用于平行传递动力概念被第一次应用于自动变速器设计。引擎输出传递给两组平行的三速模块，每一个都能独立接收动力并且传递动力，因此每一组模块都有其相对于引擎的输入比。在每一组模块中，两个行星齿轮、两个刹车片、一个离合器产生三档速度，当一个模块中的摩擦元件没有咬合时就不会传递动力。依靠六组摩擦元件，变速器可以在增高和降低档上任意组合。变速过程只需要其中的两个咬合和脱离就可完成。
基于这种概念，一个6速200Nm自动变速器生产出来了，它可以产生任何比例而且在任何速度下都可以，完全没有限制。尽管它的全尺寸为320mm，但减小的可能性还是存在的，而且装配可以很紧凑，重量也可以降低不少。
当动力只通过一个行星齿轮传递时，两组模块的速度根据引擎的速度会相应降低。这可以产生更高的效率。这种设计很简单，基本都是由现在的自动变速器的标准件组成，没有自由飞轮，启动装置是其中一组模块的一个刹车片。
下面的图例对这种变速器性能进行了说明。

两组三速结构的6速变速器使结构紧凑、重量轻、高效成为了可能，而从刹车片启动使简单控制和低热耗得以实现。

从1995年开始Roumen Antonov所领导的一个研究小组开始开发新的行星齿轮自动变速器。
到2002年，第四代概念形成了，而且原型机在各种实验车上进行了运行测试，这项工作使ATT拥有最基础的技术和主要OEM厂家不断进步的需求反馈。

在2003年，拥有专利技术的6速变速器诞生了！

Project Target:
The Antonov team decided that the new generation of transmission should fulfil the following requirements :
- Maintain existing advantages of small size, light weight , high efficiency and low costs.
- Introduce simple control, involving only two elements in changing ratios during the shifting process.
- Achieve free values for the ratio in each speed.

Obviously this was a major task requiring the invention of a new concept which should address some of the unsolved problems in the development of today’s automatic transmissions.


Concept and design :
A fifth generation Antonov 6-speed was created based on new kinematics and architecture. The concept is a new invention which is covered by patents applied for.

For the first time an automatic transmission was created that employs planetary gears in a kinematics scheme that utilises parallel transfers of power. The engine’s output goes to two parallel three-speed modules. Each of these can independently accept power and transfer it to the differential. Thus each of the two modules can have its own input ratio to the engine.

In each module, three speeds are produced by two simple planetary gears, two brakes and one clutch. When those friction elements in one module are not engaged there is no transmission of power. Under those conditions, the transmission can select upshifts and downshifts in any combination using all six friction elements. The shift is produced in combination with only two of them, engaging one and disengaging the other.

Based on this concept, an initial layout for a 6-speed 200 Nm AT was created. This transmission can produce any overall ratio and any steps in any of the speeds, without limitation. Although its overall length is about 320 mm, this has the possibility of being decreased, and packaging is very compact. Weight is much lower also.

When power is being transmitted only one of the planetary gear is carrying torque. The speed of the two modules is slightly reduced with respect to engine speed. This offers the potential for higher efficiency.

The design is simple, consisting of only standard components similar to those of current production automatics. There are no freewheels in the design. The start device is one of the brakes in one of the modules.

The following diagrams show a mathematical approach, diagram, kinematics scheme, layout of transmission and possible spread of the Fifth generation 6-speed automatic transmission.
