NTN will run an exhibit at the “Automotive Engineering Exposition 2013” with the theme “Engineering for people, cars and the future: NTN's advanced technology supporting a sustainable society.”
In addition to the “Full-drive-by-wire EV” equipped with the in-wheel motor system for electric commuters and the steer-by-wire system, a range of products and systems focused on next-generation vehicles such as EV and eco-friendly vehicles will be on display.
We look forward to seeing you at the event.
Main exhibits
Full-drive-by-wire EV
Joint research with the Kanagawa Institute of Technology on topics such as maximizing the performance of vehicles and minimizing energy consumption due to slipping tires is being conducted using an experimental “Full-drive-by-wire EV” as part of studies on the theory behind the research. In-wheel motors installed at each corner of the vehicle allows the brake and drive power of each wheel to be controlled individually, while an independent steer-by-wire system for the front wheels and rear wheels help to separately control the lateral force applied to each wheel. This enables the load that had previously been centered on one specific tire to be decreased and distributed efficiently across all four tires, which is hoped to help prevent lateral sliding and increase cornering performance. Limiting the energy consumption due to slipping tires leads to a longer tire life and improves energy efficiency.
Hub Joint with Incorporated Advanced Sensor Technology
Features a “wide-range, high-resolution small sensor” capable of detecting vehicle movements of 1 mm, and a “multi axis load sensor” that reduces the detection response time from the tires down to 1/5th that of other sensors. NTN's proprietary “press-cut spline method” has been adopted for the joint between the hub bearing and CVJ, in what is the world's first corner module product equipped with two integrated sensors.
Hollow Ball Screw Unit
Designed for drive mechanisms of electronic CVTs, the use of a hollow ball screw allows it to be installed on the same axis as the pulley drive mechanism. A thinner and more lightweight nut minimizes the loss of drive power due to pulley operation and also allows CVTs to be more compact and lightweight.
Ball Screw Drive Module
Converts the rotational motion of motors accurately to linear motion for cooperative regenerative brakes used in HVs and other vehicles. Accurate adjustments of the hydraulic brake force allow a greater amount of driving energy to be regenerated, which helps to extend the driving range.
Amorphous Core
The core of reactors and other parts feature an injection molded magnetic material comprising of a mixture of amorphous powder and resin. This keeps the inductance reduction ratio under high current and high-frequency band conditions at 30% with DC (direct current) superimposition characteristics. Injection molding means a greater flexibility in shapes, and outstanding magnetic properties allow for a more compact design.
Hub bearing for severe environment
A hub bearing designed for severe environments will be on show featuring improvements to protection against muddy water, load resistance and fretting resistance at extremely low temperatures. It is designed for durability in conditions such as on unpaved roads often found in emerging markets and in cold climates, and provides highly reliable drivability and vehicle transportation.
