Abstract

The invention discloses a supporting and limiting device for a gear rack manual steering gear. The steering gear includes a shell body and a rack, and a supporting and limiting mechanism includes a bushing and a bushing retainer ring which are disposed between the rack and the shell body; the bushing is sleeved with one end of the bushing retainer ring, a buffer retainer ring is sleeved with the other end of the bushing retainer ring, and the rack is sleeved with the buffer retainer ring; the inner wall of the bushing is provided with oil storage tanks, and the inner wall of the bushing is ininterference fit with the outer wall of the rack; and one end of the bushing is installed on the bushing retainer ring, the inner wall of the other end of the bushing is provided with a guide surface,and the outer wall of the end, provided with the guide surface, of the bushing is provided with a chamfer; and the supporting and limiting device for the gear rack manual steering gear is stable in process, convenient to assembly, and reliable in supporting.

Description

technical field [0001] The invention relates to an automobile steering gear, in particular to a support and limiting 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 and limit device for a rack and pinion mechanical steering gear with stable process, convenient as...
