The invention discloses a support device of a gear and rack mechanical steering device, wherein the steering device includes a shell body and a rack. The support limit device includes a bush arrangedbetween the rack and the shell body and a bush retaining ring, one end of the bush retaining ring is installed in the bush in sleeve, the other end of the bush retaining ring is installed in a bufferretaining ring in sleeve, and the buffer retaining ring is installed in the rack in sleeve. An inner wall of the bush is arranged in an oil reservoir, and the inner wall of the bush is in interferencefit with an outer wall of the rack. The rack is connected with a pull rod. One end of the buffer retaining ring is installed in the bush retaining ring, and the other end of the buffer retaining ringextends the bush retaining ring, wherein an end surface of the end that the buffer retaining ring extends the bush retaining ring is a pull rod limit buffer surface. The support device of the gear and rack mechanical steering device has the advantages of stable process, good buffer effect, and reliable support.
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, good buffering effect and reliabl...
