Mechanical Steering Gears TRIZ Cases
- Steering Wheel Stowage Using a Planetary Gear and Reaction Motor
A planetary gear set reuses the steer-by-wire reaction motor to slide and rapidly deploy the steering wheel while reducing added actuators, weight, and space.
- Two-Piece Pinion Shaft Tool for Press-Fit Disassembly
A keyed tool body and slide hammer overcome press-fit retention in two-piece pinion shafts, enabling rack-and-pinion repair.
- Resin Sliding Damping Stopper for Axial and Rotational Motion
A low-friction resin sliding member lets a damping stopper absorb axial impact and reduce vibration without elastic body twist during rotation.
- Steering Shaft Buffer Structure for Curb Shock Absorption
A dual-region buffer absorbs normal steering loads elastically and curb shock loads plastically, reducing steering impact without larger parts.
- Segmented Radial Rack Bearing for Quiet Steering Mesh Fit
Semi-cylindrical rack bearing segments maintain mesh fit through thermal expansion, cutting steering noise and improving feel.
- Rack Housing Mount Layout for Steering Assembly Insertability
Axially shifted steering mounting portions reduce bracket width, improving insertion through vehicle body openings while keeping stable support.
- Steering Gear Rack Forging With Wider Toothing and Larger Back Radius
A two-part die forms a steering rack with a larger back radius and wider toothing, improving force transmission while reducing wear and die complexity.
- Steering Gear Rack Production Using Continuous Grinding and Friction Welding
Continuous grinding of shaft raw material before cutting improves steering rack precision and productivity, then friction welding joins the toothed segment.
