Abstract

Disclosed is an apparatus (300) for automatically compensating for the clearance of a support yoke (310) in a rack-and-pinion steering system by using a torsion spring (370) and a cam mechanism so that, when the support yoke (310) generates a clearance, it is automatically compensated for without separate adjustment. Unlike conventional apparatuses for reducing rattle noise resulting from the increased gap between the yoke plug (360) and the support yoke (310), the disclosed apparatus maintains a constant gap. In addition, the first cam (330), the second cam (350), and the torque spring (370) automatically compensate for the clearance of the support yoke (310).

Description

field of invention [0001] The invention relates to a device for automatic compensation of backlash in a support yoke in a rack-and-pinion steering system. More particularly, the present invention relates to a device for automatically compensating for backlash of a support yoke in a rack-and-pinion steering system by utilizing a torsion spring and cam mechanism so that when the support yoke develops play, Automatic compensation without individual adjustments. Background of the invention [0002] Generally known in the art, steering systems enable a driver to steer his / her vehicle in a desired direction by changing the center of rotation of the front wheels. [0003] Figure 1 shows the main structure of a conventional automobile steering system. [0004] Referring to Fig. 1, this conventional steering system includes: a steering wheel 100 arranged in the passenger compartment; a steering shaft 105 connected to the steering wheel 100; a steering column 103 for fixing the stee...
