The Project is to research, develop, manufacture, license and monetise a new and completelyoriginal Infinitely Variable Transmission patent for Automotive and Industrial applications.The crucial operating characteristics are as follows:-Infinitely variable speed in both forward and reverse.- Multiple variable speed inputs and outputs are easily achievable, so the System can easily beadapted to act as both, the Vehicle transmission and the rear differential / Transaxle. Themajor advantages being that each wheel can be electronically speed controlled and positively /negatively driven in all dynamic conditions, it also has the capability to dramatically improvethe vehicle handling especially for e.g. during cornering, as the inner wheel can be speedreduced and the outer wheel speed increased to account for the varying distance in the trackexperienced. In low traction situations such as snow / ice and other hazardous drivingconditions both wheels are positively driven improving vehicle traction. Furthermore incertain applications the transmission is easily capable of providing forward motion on oneoutput whilst providing reverse motion on the other, so that a vehicle could turn within itsown footprint, as is often advantageous with Track and Military vehicles.- The transmission has a high commonality and a fewer number of components meaningreduced production costs compared with modern Automatic Transmissions-The system naturally adjusts for any wear in the contact elements.-Low revs at cruising speed, leading to optimal engine use, reduced engine wear and at least20% fuel or electric savings, along with increased vehicle performance.-Controlled braking is possible on each wheel, and can be possibly dispense with the ABSbraking system. Furthermore in Electrically driven vehicles regenerative braking can beoptimised though the infinite ratio the gearbox can provide. Kinetic energy recovery can alsobe easily added to the rear transaxle assembly.

该项目旨在研究、开发、制造、许可和货币化一项全新的、完全原创的汽车和工业应用的无级变速器专利。关键的操作特性如下：-无级变速在前进和后退。-多种变速输入和输出很容易实现，因此系统可以很容易地适应作为车辆变速器和后差速器/驱动桥。主要的优点是每个车轮都可以电子速度控制和在所有动态条件下的正/负驱动，它也有能力显著提高车辆的操控性，特别是在转弯时，因为内轮可以减速，外轮速度可以增加，以考虑在赛道上经历的不同距离。在低牵引力的情况下，如冰雪和其他危险的驾驶条件下，两个轮子都被积极驱动，提高了车辆的牵引力。此外，在某些应用中，变速器很容易在一个输出上提供前进运动，同时在另一个输出上提供反向运动，因此车辆可以在其足迹内转弯，这通常与履带和军用车辆有利。-与现代自动变速器相比，该变速器通用性高，部件数量少，生产成本低-系统可以自然调节接触元件的磨损。-巡航时的低转速，优化发动机使用，减少发动机磨损，节省至少20%的燃油或电力，同时提高车辆性能。-控制制动在每个车轮上都是可能的，并且可能不需要abs制动系统。此外，在电动车辆中，再生制动可以通过变速箱提供的无限比率进行优化。动能回收也可以很容易地添加到后桥总成。
