Automotive Engineering Exposition 2019 Yokohama

NTN Corporation (hereafter, NTN) will exhibit at the “Automotive Engineering Exposition 2019 Yokohama” which will be held from May 22 to 24 in Pacifico Yokohama.

Today, the automotive industry is undergoing major changes, such as the introduction of strict fuel economy regulations against the background of environmental problems, and the CASE (Connected, Autonomous, Sharing/Service, Electric). Various needs are emerging as a result of these regulations and changes.

With the theme of “Make The World Nameraka*,” NTN will exhibit a wide range of products that respond to the various needs of the automotive market, such as improving vehicle fuel efficiency, electrification, and driving stability.

In the exhibition, NTN will introduce high-performance bearings that realize functions such as high-speed rotation, low friction, and longer life, and high-efficiency driveshafts. Furthermore, a variety of module products that utilize technologies developed over many years such as “sHUB,” Hub Bearing with Steering Assist Function, “eHUB,” Hub Bearing with Motor Generator Function, and “Electric Motor and Actuator” series.

We look forward to your visit.

Main exhibits

Low Friction Hub Bearing III

A hub bearing (a component that supports rotation of tires) reducing rotational friction by 62% and improving vehicle fuel efficiency by approximately 0.53% compared to the conventional product. By improving ingredient and viscosity of grease, applying seal structure with labyrinth, and optimizing the preload inside the bearing, the product reduces the rotational friction of the bearing itself with maintaining the performance. Additionally, it can prevent the fretting wear* in low-temperature condition.

Compact Chain Tensioner for Low Fuel Consumption

The Hydraulic chain tensioner which contributes to fuel efficiency of engines. By circulating the oil inside the tensioner, the amount of oil required to operate the chain tensioner is drastically reduced. The size and weight reduced by simplified structure also contribute to fuel efficiency. In addition, by using the oil stored inside the tensioner, the product can maintain the tension of the chain with appropriate oil pressure immediately after the engine starts, and suppresses rush noise due to insufficient tension of the chain.

“sHUB,” Hub Bearing with Steering Assist Function

A hub bearing with a steering assist function that can be equipped on the front wheels by combining a mechanism that adjusts the steering angle of the tires on a hub bearing. The hub bearing with a steering assist function that can be equipped on the front wheels is the industry's first product. Optimally correcting the steering angle at the left and right wheel improves both stability when moving forward at high speed and vehicle cornering performance in addition to also contributing towards improved fuel efficiency while also stabilizing the vehicle during emergencies such as when the vehicle starts to skid.

“eHUB,” Hub Bearing with Motor Generator Function

Module product with a motor generator integrated into a hub bearing. For front-wheel drive vehicles, the product is installed in the rear (non-driven) wheels to reduce engine load and assist with power regeneration when vehicle starts and accelerates. The modified version has been developed with an optimized internal structure for a much more compact size and significant improvement in permitted rotational speed with the same level of performance as conventional products.

Electric Motor and Actuator

Combine its core technologies of bearings and ball screw product technology with motor design technology and electrical control technology for controlling vehicles to develop the “Electric Motor and Actuator” series. The product lineup features common components and specifications, and available with variations in shape and size, which eliminates the need for individual designs and contributes to a shorter development time.

Ultra High-angle and High-efficiency Fixed Constant Velocity Joint “CFJ-W”

Driveshaft for front that achieved both the “world's highest maximum operating angle of 55°” and an “approximate 50% reduction in torque loss compared to conventional products.” NTN strengthened each component, improved lubrication and adopted NTN's proprietary structure. This product contributes towards improved vehicle turning and lower fuel consumption.

ULTAGE Tapered Roller Bearing for Automotive Application

A tapered roller bearing for automobiles that delivers the world's highest standard of high-load capacity and high-speed rotational performance. The optimal design technology of tapered rollers that maximizes the rolling operating life, that was used for the large size tapered roller bearing, has been modified as a more compact series lineup. This optimal design gives the bearing a high-load capacity that is 1.3-times higher than the conventional product, and improves the rated life by 2.5-times or more. Sliding contact zone between the rollers, inner ring and retainer are also optimized, which raises the permitted rotational speed by approximately 10%.
