The New-CVT transmission (patent pending) is (almost) as efficient as a single-speed transmission, functionally alike a CVT (meaning it has many gear ratios), suitable for high torque, compact, light and cheap. Its only defects are that it needs to be computer controlled and that drive must be disengaged while changing gear.

2024年12月14日 · Italian company Alter Ego, led by mechanical engineer Edyson Pavilcu and supported by research from Milan Technical University, has introduced the world’s first geared continuously variable transmission (CVT).

2024年12月18日 · Invented by a team of engineers in Italy, it’s called the “Ratio Zero” transmission; let’s call it the RZT for short. If you need a refresher on the mechanics of an automotive gearbox, the first...

The new-CVT High resolution version (16000 x 12000) Here we see the idea of the multi-ratio gear and that of the conical involute gear combined into the new type of transmission that we call the 'new-CVT'. We see a cascading set of gears whereby each …

2024年4月11日 · Below are the vehicles, including hybrids, that offer CVTs or eCVTs for the 2024 model year. For vehicles with multiple engine options, some may not be mated to a CVT. CVTs have specific...

2024年12月6日 · Italian company Alter Ego, led by mechanical and automation engineer Edyson Pavilcu and assisted by kinematic studies undertaken at the Milan Technical University, says it's prototyped a...

2024年12月14日 · cvt（无级变速器）是一种不同于传统自动变速箱（at）和手动变速箱（mt）的变速系统。 与传统变速箱依靠固定的齿轮比来实现不同的车速和动力输出不同，CVT变速箱通过两个锥形皮带轮和一条皮带或者链条，连续无级地调节传动比。

We are developing a few prototypes based on a New-CVT version with 9 conical involute gears and starting with 8 teeth. So we have optimized the source code for this version. In order to make sure that the prototypes were perfect in every detail, we made an animation of each gear in the main gear as it intermeshes with a pinion gear.

A continuously variable transmission (CVT) is designed to provide a smooth journey by seamlessly shifting through an infinite range of gear ratios to best match driving conditions. In the early years of development, Nissan saw the benefits of the technology, including ultra-smooth acceleration and low fuel consumption, and began mass ...

The new CVT combines conventional CVT belt operation with an auxiliary gearbox and has a significantly increased gear ratio range – roughly 20 percent higher than other CVTs and among the...
