NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Toshihiro Uchiyama) has developed a new Parallel Link type Active Suspension corner module. This product will be exhibited at Tokyo Motor Show 2017 at Tokyo Big Site from Saturday, October 28 to Sunday, November 5, 2017.
The ground-breaking Parallel Link type Active Suspension combines NSK's world-class ball screw technology with a motor to enable a range of motion so free you might consider it a living being. In addition to standard left-right turning, this system can adjust the wheels to have a negative camber angle, which allows for greater stability at high speeds, including when turning.
The actuators are able to be repositioned (extend, contract, etc.), making it possible to change the vehicle wheelbase. The shorter the distance between front and rear wheels, the tighter a vehicle can turn, which also makes it easier to parallel park.
Further, the Parallel Link type Active Suspension can reduce vibrations while driving, and delivers a much wider range of motion through all four wheels. This technology will be the hands and feet in both electric and conventional vehicles.
