Parker Hannifin introduces its LORD Pressure Suggestions System (FFD) an built-in resolution combining a steering sensor, a magnetically responsive variable brake for instantaneous and clean 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 shall be tasked with growing snug, intuitive, and straightforward to function machines. Our FFD facilitates essentially the most direct reference to finish customers, creating the texture within the operator’s palms. This supplies OEMs with an amazing alternative to distinguish their automobiles,” stated Zach Allen, product advertising supervisor for Industrial Options at Parker.
The converging traits 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 street wheels, which has challenged OEMs in offering the operator with a high-quality steering really feel. When mixed with shrinking, and infrequently growing old, labor forces, offering a premium operator expertise is paramount for OEMs and their finish clients. The LORD FFD permits extremely responsive SbW techniques, enhancing operator confidence.
Additional, our FFD supplies an distinctive, low-effort, steering efficiency which boosts operator consolation and supplies further design flexibility to the OEM. The mixed results of enhanced operator confidence and luxury in the end 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 package deal, 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 offer crisp end-stops however since it’s a semi-active system, it doesn’t pose a problem for purposeful security. The servo motor supplies the mandatory haptic performance in a compact dimension and is straight coupled to the steering shaft with none gears. The absence of a planetary gear practice supplies the most effective haptic really feel and low inertia. On-board electronics with built-in connectors facilitate a small area 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.
For the reason that 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.
