THK Verifies Its Technology by Mounting Original Components on an Electric Vehicle. Public road tests conducted in the suburbs of Graz, Austria

THK has recently conducted a public road test of the LSR-06, an electric vehicle equipped with components currently undergoing technical verification. This test, performed on the outskirts of Graz, Austria, brings the company one real step closer to verifying its technology.

The LSR-06 is the successor to the LSR-05, whose advanced EV technology was highlighted at the Japan Mobility Show 2023 and Paris Motor Show 2024. THK will continue to verify the advanced technology in this EV which is now able to be driven on public roads. Its design was crafted by SN DESIGN PLATFORM (Representative Director and CEO: Shiro Nakamura), and both companies worked hand in hand to make it the manifestation of a new vision for the mobility of the future.

Advanced EV Technology Tested on Public Roads

Active Level Control Suspension: ALCS

This system uses a THK ball screw/spline to enable vehicle height adjustments and attitude control according to the roughness of the road and the driver’s steering. It lowers the height of the vehicle when traveling at high speeds to reduce air resistance, and it can even raise the car height when off-roading or driving over bumps.

Original software developed by THK is also installed to enable high-speed and high-precision control of the active suspension.

MR Fluid Active Damper Tube: MRDT

THK offers seismic isolation technology in the form of rotary dampers that utilize ball screws along with a viscous element that absorbs and dampens tremors. Combining this product technology with MR fluid allows the damping power of the suspension to be controlled electronically to absorb vibrations and facilitates coordination with the ALCS, which controls vehicle height.
