Mechanical Steering Gears TRIZ Cases

A steering apparatus positions the support frame and fixation part off the rotation center axis line to transmit wheel rotation without blocking the inner circumferential side.

Electric motor drives ball screw nut meshed with sector gear to replace hydraulic boost and reduce system complexity.

An offset inner peripheral surface in the stroke restricting portion distributes loads and prevents cracks from tensile stress.

Stop member absorbs torsional loads from the rack, shielding the compression body from harmful stress and extending service life.

Dual sub-gears and rotors detect rack bar rotation angles via impedance changes, resolving steer-by-wire complexity.

A control device computes a motor neutral point using steering angle detection values to ensure accurate absolute steering angle measurement.

A grease composition with boron nitride and amide compounds maintains low friction at steel-resin sliding areas.

A steer-by-wire screw mechanism converts rotational motion into axial displacement to constrain steering wheel rotation.

Elastomeric support between outer ring and housing eliminates metallic noise during rotation changes while maintaining wear compensation reliability.

Replacing complex GMR sensors with a mechanical gear rack and linear sensor reduces manufacturing cost while maintaining high steering angle precision.

Integrating a polyamide guide bushing into the sealing cover simplifies assembly and reduces wear on the steering rack.
