Honda Patents 11-Speed, Triple-Clutch Transmission

Honda has filed a new patent with the Japan Patent Office for a new transmission which features 11 speeds and three clutches. 

In the description, Honda says that by using a third clutch, it will be able to decrease torque removal that occurs with dual-clutch transmissions. The patent application, which is translated from Japanese, also says that the new transmission will allow “speed change to be more effectively restricted and a speed change response to be increased.”

In a series of drawings, which you can view here, Honda lays out the transmission, describing an 11-speed unit.

There is no mention of what type of vehicle this transmission would eventually find a home in, though it sounds like it is being designed to improve efficiency, so a small fuel economy-minded car could be ideal.

The application was published on May 27, 2016 and is registered to Honda Motor Co Ltd. The inventor credited is Izumi Masao.

    What’s the name of that honda car in the picture?

    What’s the benefit over a CVT? Any MEs out there explain?

  • Hasan

    No need for changing gears so torque doesn’t drop off at any time, engine speed can be kept at a certain rpm level with the throttle so max engine efficiency can be gained by keeping at the rpm point where max torque occurs, ratios change continuously with speed so a high speed can be gained along with the fuel economy benefits of low rpm, so the CVT is good for a lot of things. But the ones available on the market right now are fragile and unsuitable for high powered engines.
    P.S. Not an M.E, more like an E.E

    ME and transmission engineer. CVTs right now have issues with ratio span. Traditional automatics and manuals you can have a a wider ratio which means smoother starts and lower rpm at high speeds, where a CVT you are basically limited to choosing one or the other. CVTs work pretty good in city traffic though efficiency wise. I wise I could see the power flow though for this 11 speed so I could add more info. Image link isn’t working for me. Anyone got a mirror?
