Nippon Seiko Co., Ltd. successfully developed a steering column with high safety, high weight, high vibration rigidity*1 in the event of a collision, and the steering column can be adjusted up and down/front and rear*2. Currently the product has Started to go on sale.
Resin pin internal retracting steering column
Development background
In the car's three major functions 'driving', 'steering', 'stop', the steering column is a component that can achieve the 'steering' function.
In addition, in the event of a crash, the steering column can absorb the impact load on the driver during impact by its own crushing mechanism, thereby improving safety.
Nowadays, people are increasingly demanding environmental protection while pursuing high safety and high comfort. The steering gear products also face the challenges of these demands.
In response to these demands, NSK has developed adjustable steering column for up and down/front and rear.
*1: High-vibration rigid steering column has a higher resonance frequency. In general, the higher the vibration rigidity, the harder it is for the driver to feel the external vibration.
*2: Up and down/front and rear adjustable steering column is the steering column whose steering wheel can be adjusted in the up and down direction and the front and rear direction.
Product Highlights
◆Using a new detachment structure to improve safety (reduced load variation by 25%) By setting the detachment structure on the steering column tube, the detachment load of the steering column integral structure can be kept constant. Stable absorption of impact energy, which in turn improves safety.
◆ Compared with the original product, the weight is reduced by about 15% (about 560g), which makes it lighter. By changing the structure, the number of parts of the product is reduced, and the appearance of the product is simplified. The weight reduction of the column helps to improve the fuel economy of the car.
◆ Compared with the past, the vibration rigidity is increased by about 11% (about 7 Hz), and the comfort is improved. By optimizing the design of the tilt bracket, the product has high vibration rigidity. In addition, the stability of the steering wheel operation is improved and Comfort.
The resin-pinned internal retracting steering column developed by NSK further enhances the safety, comfort and environmental friendliness of the car.
