Honda DN-01 - the worlds first lockup mechanism that offers superior throttle response.
30th October, 2007
Honda will be displaying the DN-01 at the Tokyo Motor Show with details of their Human Friendly Transmission, or HFT. It says it is scheduled for market launch but I’m not sure if they mean immediately or sometime in the near future. I think this one will be pretty popular with the growing demand for automatic transmission equipped motorcycles. Will automatics begin to move into the mainstream and take over in the same way they did in cars?
The Honda DN-01 is a large, automatic sports cruiser equipped with Honda's own infinitely variable hydraulic mechanical "HFT" transmission with the world's first lockup mechanism that offers superior throttle response.
The transmission is coupled to a 680cm3 water-cooled, 4-stroke V-type, 2-cylinder engine.
The HFT is a compact and highly efficient encompassing functions for starting, power transmission and shifting, all on a single shaft.
The basic configuration of the system consists of an oil pump for converting engine power into hydraulic pressure, and an oil motor for converting the hydraulic pressure back into power for output.
The HFT's lockup mechanism works to minimize transmission efficiency losses, contributing to improved fuel economy.
The DN-01 offers both easy to operate features and the intrinsic sporty ride of a motorcycle and features a spacious riding position created by the low seat height, a wide and long passenger seat, and creative, organic styling that ensures joy in ownership.
The DN-01 is a new automatic sports model designed with the pursuit of fine quality throughout the entire motorcycle.
More details below:
With the aim of providing products useful in the every day lives of customers, Honda has developed and sold motorcycles equipped with easy-to-operate automatic riding technologies. As a pioneer in the era of automatic systems, Honda launched the Super Cub C100 in 1958, equipped with an automatic centrifugal clutch mechanism, which allowed riding without the need of clutch operation. The Eara (750cc), released in 1977, was a first large-sized motorcycle featured a torque converter in Japan. In 1980, Honda put the Tact on the market, a machine equipped with the Honda original continuously variable transmission, the V-Matic, and Honda has continued to develop a variety of new mechanisms up into the present.
[ Characteristics of the HFT ]
A transmission system with a wide range of functions in a single unit, the HFT is a compact and highly efficient infinitely variable transmission system encompassing functions for starting, power transmission and shifting, all on a single shaft. The basic configuration of the system consists of an oil pump for converting engine power into hydraulic pressure, and an oil motor for converting the hydraulic pressure back into power for output. Both are made up of multiple pistons, a distributor valve and a swash plate for piston operation, while the cylinders are integrated into the output shaft, forming the characteristic structure of the HFT.
The HFT also features the world’s first* lockup mechanism for an infinitely variable hydraulic mechanical transmission. When cruising, this lockup mechanism works to minimize transmission efficiency losses, contributing to improved fuel economy.
