Parker Hannifin introduces its LORD Pressure Suggestions Gadget (FFD) an built-in answer combining a steering sensor, a magnetically responsive variable brake for instantaneous and easy steering really feel, and an electrical motor for energetic steering options.
“We’re enthusiastic about this subsequent step in steer-by-wire (SbW) suggestions. As electrical steering adoption will increase, and the labor pool continues to shift to much less skilled operators, OEMs can be tasked with growing comfy, intuitive, and straightforward to function machines. Our FFD facilitates probably the most direct reference to finish customers, creating the texture within the operator’s arms. This gives OEMs with an incredible alternative to distinguish their autos,” stated Zach Allen, product advertising and marketing supervisor for Industrial Options at Parker.
The converging tendencies of electrification and autonomy are driving OEMs to more and more undertake SbW techniques of their car product roadmaps. With SbW techniques there is no such thing as a mechanical connection between the steering wheel and highway wheels, which has challenged OEMs in offering the operator with a high-quality steering really feel. When mixed with shrinking, and infrequently getting old, labor forces, offering a premium operator expertise is paramount for OEMs and their finish clients. The LORD FFD allows extremely responsive SbW techniques, enhancing operator confidence.
Additional, our FFD gives an distinctive, low-effort, steering efficiency which boosts operator consolation and gives further design flexibility to the OEM. The mixed results of enhanced operator confidence and luxury finally result in elevated productiveness.
The FFD combines a Magneto-Rheological (MR) brake with a small servo motor and on-board electronics. On this built-in bundle, the MR brake and the motor work collectively to optimize efficiency for the operator.
The benefits of FFD embody its small dimension, low energy necessities, a excessive bandwidth haptic really feel and simplified structure. The MR brake is giant sufficient to supply crisp end-stops however since it’s a semi-active machine, it doesn’t pose a problem for purposeful security. The servo motor gives the required haptic performance in a compact dimension and is immediately coupled to the steering shaft with none gears. The absence of a planetary gear prepare gives the perfect haptic really feel and low inertia. On-board electronics with built-in connectors facilitate a small house declare which helps with integration choices.
The brand new LORD FFD product being launched for the off-highway market in 2025 options SIL2 structure with quad redundant angular place sensors and CAN Bus communication per SAE J1939 specs. This can be utilized for each 12 VDC and 24 VDC techniques.
Because the MR brake is extremely environment friendly, the facility consumption for full torque is lower than 12 watts. The excessive bandwidth of the servo motor is finest in offering return-to-center performance, energetic force-feel like wheel slipping, vibratory haptic warning alerts (like chirp and dither) and command-following for a number of steering synchronization or autonomy.
