The invention relates to the technical field of steering, and discloses a gap adjusting device and a gear rack steering gear. When the gear rack steering gear is assembled, a friction plate of at least one gap adjusting device is located on the side, back to a gear of a gear rack mechanism, of a rack; and the clearance adjusting piece is used for providing pressure for the friction plate to enable the friction plate to abut against the acting force of the rack so that the radial clearance during rack assembling is eliminated. When the gear rack steering gear works, the radial clearance of the rack is eliminated through elastic deformation of the clearance adjusting piece so as to guarantee stable movement of the gear, the radial clearance generated by abrasion of the tooth profile of the rack can be dynamically compensated, and the buffering effect can be achieved when the gear rack steering gear is subjected to impact loads so as to absorb shock and reduce noises. The friction force between the rack and the gap adjusting device in the moving process of the rack is reduced through the friction plate, and the abrasion and noise are reduced; and the friction plate is supported through the base body so as to avoid plastic deformation of the friction plate, and the service life of the gap adjusting device is prolonged.

    本发明涉及转向技术领域,公开了一种间隙调节装置及齿轮齿条转向器,装配齿轮齿条转向器时,将至少一个间隙调节装置的摩擦片位于齿条背对齿轮齿条机构的齿轮的一侧,利用间隙调节件为摩擦片提供压力使摩擦片抵接于齿条的作用力,以消除齿条装配时的径向间隙。齿轮齿条转向器工作时,利用间隙调节件的弹性形变消除齿条径向间隙以保证齿轮平稳移动,不仅能动态补偿齿条齿形磨损产生的径向间隙,还能在齿轮齿条转向器受到冲击载荷时进行缓冲作用以减震降噪。通过摩擦片减小齿条移动的过程中与间隙调节装置之间的摩擦力,减磨降噪;通过基体对摩擦片支撑以避免摩擦片发生塑性形变,延长间隙调节装置的使用寿命。
