The invention relates to the field of automobile steering systems, in particular to a supporting seat clearance automatic compensation structure for a rack-and-pinion steering gear. Comprising a gear seat and a gear shaft rotationally connected with the gear seat, and further comprises a bearing base fixedly arranged on the side of the gear seat; the tight supporting mechanism is arranged on the side, close to the gear seat, of the bearing base and comprises a tight supporting spring, a tight abutting short shaft, a tensioning short shaft and two fastening tension springs, one end of the tensioning short shaft is fixedly connected with the gear seat, the tight abutting short shaft is arranged on the side, away from the gear seat, of the tensioning short shaft, the tight supporting spring is arranged outside the tight abutting short shaft in a sleeving mode, and the two fastening tension springs are arranged on the two sides of the tensioning short shaft. The two fastening tension springs are arranged on the two sides of the tensioning short shaft respectively. The calibration mechanism is connected with the bearing base and comprises a traction rope capable of driving the abutting short shaft to move; the metering mechanism is arranged on the side, away from the abutting short shaft, of the bearing base and comprises a dial capable of mapping the moving degree of the abutting short shaft. According to the structure, the gap of the gear shaft can be automatically adjusted, and an operator can conveniently check the intermittent adjustment degree.

    本发明涉及汽车转向系统领域,具体是涉及一种齿轮齿条式转向器用支承座间隙自动补偿结构。包括齿轮座和与齿轮座转动连接的齿轮轴,还包括:承托底座,固定设置在齿轮座的旁侧;撑紧机构,设置在承托底座靠近齿轮座的一侧,包括撑紧弹簧、抵紧短轴、拉紧短轴和两个紧固拉簧,拉紧短轴的一端与齿轮座固连,抵紧短轴设置在拉紧短轴远离齿轮座的一侧,撑紧弹簧套设在抵紧短轴的外部,两个紧固拉簧分别设置在拉紧短轴的两侧;校准机构,与承托底座相连,包括能带动抵紧短轴进行移动的牵引绳;计量机构,设置在承托底座远离抵紧短轴的一侧,包括能映射紧短轴移动程度的刻度盘。本结构能自动调节齿轮轴的间隙,且便于操作人员查看间歇调节程度。
