I'm quite happy that Geely is intending to implement the Antonov transmissions in future as I want my next car to be also Geely.
Realy cool to have foreign friend at our forum. Very glad to meet You.

15 January 2007
The Board of Antonov plc is delighted to announce that it has signed a Production Licence Agreement with Zhejiang Geely Automobile Gearbox Co, the transmission manufacturing subsidiary of Geely Automotive (“Geely”). This follows the announcement on 27 November 2006 that Geely and Antonov had signed Heads of Agreement for the licence, which is for the production of the Company’s TX6 six-speed automatic transmission.
Under the licence, Geely will have the non-exclusive worldwide rights to manufacture and sell transmissions covered by the Antonov 6 speed automatic patents and will also receive design support from Antonov.
Antonov will receive both Licence Fees totalling Euro 900,000 payable over the next nine months and then a production royalty on each transmission produced.
Geely is one of China’s leading automotive companies and is listed on the Hong Kong stock exchange and currently produces around 200,000 cars per annum and continues to grow strongly. Both companies will be working together to incorporate the TX6 into a number of models with production commencing in 2008.
Geely have already taken two models of conventional automatic transmission to production and the Antonov TX6 will be an addition to this model line-up. The transmission will also be available to other vehicle makers worldwide.
John Moore, CEO of Antonov plc, said:
“I am very pleased to be able to confirm this licence agreement. Geely has a strong track record in developing transmissions and their experience and established infrastructure will allow us to bring our technology to production rapidly. China is a key market for our technology and Geely provides an excellent customer reference site, which will underpin our commercialisation strategy in the region.”
Mr. An Conghui, Vice President of Geely Automotive, said:
“Geely is delighted to have secured the Antonov TX6 license which in turn has strengthened our transmission product range and enabled us to bring to market a vehicle which will incorporate Antonov technology delivering a compact and cost effective solution . We look forward to working with the Company closely as we move towards volume production in 2008”.For more information, see

Supurb technology for Geely
http://www.antonov-transmission.com/pas ... arauto.htmSix-Speed Automatic
Market Issues:
Efficiency of conventional autos too low but CVT requires dependence on specialist belt supplier
Efficiency can be improved by use of wet clutch launch not torque converter but this requires wider ratio range from transmission
Wider ratio range requires additional speeds to retain optimal powertrain efficiency and good shift quality leading to higher cost and weight
Problem Statement:
How to achieve a compact, high efficiency transmission with 6 speeds, no multi-clutch shifts and no specialist components?
Antonov Solution:
The six-speed makes use of simple planetary gear sets arranged on two countershafts
Combination of planetary and countershaft layout provides multi-speeds with simple shifting and high efficiency
Solution is light and compact and scalable to all transverse installations
Status
Transmission has reached Concept Readiness and initial production designs have been completed
Concept Demonstrators successfully signed off by a customer as being ready for the production design phase. Supplier nomination and production planning now under way

Since 1995 Roumen Antonov, together with a small team of engineers, has explored novel planetary automatic transmissions.
By 2002, four generations of innovative concepts had been developed and prototyped in running demonstrator cars of various types. This work enabled AAT to build up essential expertise as well as gain feedback from major OEM’s resulting in a constant evolution from generation to generation.
Created in 2003, the Antonov 6 Speed Automatic Transmission is based on new kinematics and architecture and protected by patents.
For the first time a combination of planetary gears and parallel transfers of power has been created. The engine’s output is transferred to two parallel three-speed modules. Each of these can independently accept power and transfer it to the differential.
In each module, three speeds are produced by two simple planetary gears, two brakes and one clutch. Using the friction elements the transmission can select up-shifts and down-shifts in any combination. Each shift is produced with only two friction elements, one engaging and one disengaging simultaneously. Reverse is also provided in one module.
The transmission is very flexible, it can produce any overall ratio and any steps between any of the speeds. When power is transmitted, only one of the planetary gears is carrying torque. The speed of the two modules is slightly reduced with respect to engine speed. There are three direct drives on 4th, 5th and 6th speed, and there are no freewheels in the design offering the potential for higher efficiency.
The start device is one of the wet brakes in one of the modules. This enables easy and effective calibration of launch, with low thermal loading of the friction elements. It also enables the torque converter to be eliminated which reduces cost, weight and size whilst improving efficiency. The system is modular and four, five, six or more speeds versions can be chosen to suit a particular cost and application requirement.
The end result is a compact, lightweight automatic transmission applicable to a wide range of vehicles. This simple design consists of standard components similar to those of current production automatics offering low cost of development and easy new product introduction.
