By integrating the energy absorption strap with the telescope drive nut, this steering column design cuts parts and assembly cost while preserving impact energy dissipation.

A non-uniform groove structure tunes steering shaft bending during a crash, improving passenger-compartment protection with simpler manufacturing.

A curved energy-absorption groove and strip absorb crash loads while preventing steering column drop that can cause secondary driver injury.

A plastically deformable member lets the steering column translate forward during secondary impact while preserving wheel adjustment stability.

A one-piece steering shaft uses a hardened smaller-diameter section to absorb impact energy, cut assembly steps, and improve torque transmission reliability.

A single-sheet breakaway strap uses weakening and bent geometry to tune steering column crash energy absorption across impact conditions.

A grooved sliding bearing shell and spring preload simplify steering column assembly while improving axial rigidity and reducing friction.

A detachable friction plate and wire impact absorber let the steering column move forward and absorb more secondary collision load.

A reduced-cross-section passage plastically deforms an absorption part to dissipate crash energy in a compact steering column assembly.

A carrier plate extends and supports the deformation strip beyond the casing tube, increasing crash energy absorption without a longer column.

A press-fit inner tube inside a hollow steering spindle boosts stiffness and natural frequency without the cost or weight of thicker sections.

A telescopic shroud, spring, and blocking mechanism manage steering shaft collapse during a crash to absorb energy and move the wheel away.

A dual steering-column absorber packs a deformation strip and switchable strap in series to save space and match crash severity.

Radial flange-to-housing engagement keeps the steering shaft and housing coaxial, simplifying EPS assembly and avoiding centering work.

A coaxial inner-outer energy absorber simplifies steering column structure while delivering uniform crash deformation and high stiffness.

A stop carrier moves the limiting elements outward, freeing space for crash energy absorption while avoiding rotational impulses and noise.

A bevel box and adapter plate let commercial-vehicle EPS accept angled input shafts, easing cab packaging and integration in tight spaces.

A three-segment telescopic steering column extends stroke length while staying compact and uses static polymer-coated interfaces to cut noise and friction.

An integrated holder and reducing part links steering adjustment and crash damping to cut fastening parts, mass, and assembly complexity.

A slotted shroud and fastener interface enables threshold-load breakaway, avoiding mid-collapse load spikes in steering columns.
