This utility model discloses a
noise reduction structure for an adjustment body of an automotive steering gear, including a steering housing, an adjustment housing, and a steering rack. The adjustment housing houses the
noise reduction structure, which includes an adjustment plug, a rack support, a spring, a friction
assembly, a sidewall anti-collision
assembly, and a compression anti-collision
assembly. A connecting groove is formed in the right end of the rack support, and the friction assembly is installed in the connecting groove. The sidewall anti-collision assembly is installed between the rack support and the adjustment housing, and the compression anti-collision assembly is installed between the adjustment plug and the rack support. The steering rack is movably embedded in the steering housing, with its sidewall in contact with the inner wall of the friction assembly. This utility model relates to the field of automotive steering gear technology. Through the coordinated operation of the friction assembly, the sidewall anti-collision assembly, and the compression anti-collision assembly, it effectively buffers and suppresses abnormal
noise from steering rack friction, lateral impacts between the rack support and the housing, and
axial compression collisions between the adjustment plug and the rack support, achieving a comprehensive
noise reduction effect.
