Abstract

The invention discloses a supporting device of a gear and rack mechanical steering gear. The steering gear comprises a shell and a rack. A supporting and limiting mechanism comprises a lining arrangedbetween the rack and the shell, and a lining check ring; one end of the lining check ring is mounted on the lining in a sleeving mode, the other end of the lining check ring is arranged on a buffering check ring in a sleeving mode, and the rack is sleeved with the buffering check ring; the inner wall of the lining is provided with oil storage tanks, and the inner wall of the lining and the outerwall of the rack are in interference fit; a sleeve arranged on the rack in an empty sleeving mode is arranged on the inner wall of the lining check ring, a first mounting step for mounting the liningis arranged in the position, located on one side of the sleeve, of the inner wall of the lining check ring, and a second mounting step matched with the buffering check ring is arranged in the position, located on the other side of the sleeve, of the inner wall of the lining check ring; a guiding conical face is arranged on the outer wall of the end, provided with the first mounting step, of the lining check ring; and the front end of the second mounting step of the lining check ring makes compression contact with the buffering check ring, and a rear end guiding conical face is arranged at therear end of the second mounting step of the lining check ring. The technique is reliable, assembling is convenient, and supporting is reliable.

Description

technical field [0001] The invention relates to an automobile steering gear, in particular to a supporting device for a rack and pinion mechanical steering gear. Background technique [0002] In order to improve the service life of the rack and pinion mechanical steering gear and the steering system, when the rack and pinion steering gear is designed for the mechanical steering gear assembly, a support limit device is usually designed to reduce friction and support the rack. . Commonly used support and limit devices usually have only one bush embedded in the housing to achieve the purpose of supporting the rack. Such a simple supporting and limiting device is unstable in assembly process and easily leads to quality problems. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a support device for a rack and pinion mechanical steering gear with stable process, convenient assembly and reliable ...
