Abstract

The invention discloses an automobile steering system gear shaft and lengthened rod connection structure, comprising a base, an inner sleeve, a spring and an outer sleeve; the base is welded to one end of a lengthened rod; the inner sleeve is fixed to one side of the base far away from the lengthened rod; the inner sleeve is sleeved with the outer sleeve; the spring is arranged between the base and the outer sleeve; one end of the spring is in contact with the base; the other end of the spring is in contact with the end face of the outer sleeve; the end, close to the base, of the inner wall ofthe inner sleeve is provided with splines matching with a gear shaft; the end, far away from the base, of the inner sleeve is extended out to form a stop protrusion for controlling a movement distance of the outer sleeve; the inner sleeve is provided with a plurality of spherical holes, evenly along the periphery, between the splines and the stop protrusion; each spherical hole is internally provided with a steel limiting ball; the inner wall of the outer sleeve is provided with a stop step corresponding to the stop protrusion. The automobile steering system gear shaft and lengthened rod connection structure has the advantages that assembly and disassembly time is shortened so that efficiency is improved, poor assembly of bolts in the prior art is avoided, and chances for generating noiseare slimmed.

Description

technical field [0001] The invention belongs to an automobile steering system with an extension rod, and in particular relates to a connection structure between a gear shaft of an automobile steering gear and an extension rod. Background technique [0002] The existing automobile gear shaft and the extension rod are fastened by bolts after being connected by splines. The steering gear is installed in the engine compartment, the extension rod is installed in the cockpit, and the gear shaft is connected with the extension rod through the opening of the front wall. The opening of the front wall is affected by space and avoiding air leakage. The opening is small, and there are pedals and other parts around the extension rod. It is difficult and time-consuming to tighten and remove the extension rod and gear shaft mounting bolts with tools. ; And there are sometimes cases where the bolts are distorted by improper operation, resulting in abnormal noise at the installation place a...
