Abstract

A compact rack structure of an automobile steering column is characterized in that two rack positioning convex blocks of an axial moving rack are respectively clamped into the lower part of a limitingplatform of a radial soft limit and the upper part of a positioning plate to assemble an axial moving rack and a radial soft limit together, the radial soft limit is assembled to the position of thepositioning bulge of a radial rack, a positioning through hole, a limiting through hole and a rack through hole are aligned, an axial spring is arranged between the radial soft limit and the radial rack, a handle bushing is inserted from the concave step of the radial rack, a bushing cap of the handle bushing is clamped at the concave step, the body of the handle bushing penetrates through the positioning through hole, the axial spring, the limiting through hole and the rack through hole to assemble the radial rack, the axial spring, the radial soft limit and the axial moving rack together, and a handle clamping spring is arranged at the extending end, penetrating through the rack through hole, of the handle bushing to position the handle bushing in order to form an integral compact rack structure. The structure is compact, and the requirement of customers for the arrangement space is met.

Description

technical field

[0001] The invention relates to the field of auto parts, in particular to a compact auto steering column rack mechanism applied to an auto steering system. Background technique

[0002] At present, with the rapid development of my country's automobile market, sales and output have increased and decreased year by year, and major automobile manufacturers have higher and higher performance requirements for steering columns, one of the key components of automobiles. In addition to the need for good clamping efficiency and elimination of adjustment noise for the steering column, the clamping mechanism of the steering column also needs to meet high axial and radial holding force requirements. It will limit the space layout of the entire clamping system, so the clamping mechanism is required to have the characteristics of high performance and compact structure.

[0003] However, the prior art generally puts forward requirements on the design of the clamping mechani...
