The invention discloses a supporting limiting device of a gear rack manual steering gear and a supporting method. The steering gear comprises a shell body and a rack, wherein a supporting limiting mechanism comprises a lining and lining retainer ring arranged between the rack and the shell body, the lining is sleeved with one end of the lining retainer ring, a buffering retainer ring is sleeved with the other end of the lining retainer ring, the rack is sleeved with the buffering retainer ring, the inner wall of the lining is provided with an oil storage tank, the inner wall of the lining is in an interference fit with the outer wall of the rack, the inner wall of the lining retainer ring is provided with a sleeve covering the rack, the lining retainer ring locating at one side of the sleeve is provided with a first mounting step provided with the lining, and the lining retainer ring located at the other side of the sleeve is provided with a second mounting step matched with the buffering retainer ring. The supporting limiting device has the advantages of stable process and good supporting reliability.
Description
technical field [0001] The invention relates to an automobile steering gear, in particular to a support limiting device and a supporting method 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 limiting device and a support method for a rack-and-pinion mechanical steerin...
