The invention relates to a tractor steering column transmission shaft buffering device and a steering column, and relates to the field of agricultural machinery, the tractor steering column transmission shaft buffering device comprises an assembling supporting assembly, a limiting supporting plate, an elastic block, at least two limiting shafts and at least two connecting shafts, the assembling supporting assembly is provided with at least two limiting holes, and one end of each connecting shaft is fixedly connected with the assembling supporting assembly; and the at least two limiting shafts and the at least two limiting holes are arranged in a one-to-one correspondence mode, one ends of the limiting shafts are fixedly connected with the limiting supporting plate, and the other ends of the limiting shafts penetrate through the elastic block and the corresponding limiting holes from the other side of the elastic block. The steering gear has the beneficial effects that the elastic block can reduce impact in the steering gear and transmit the impact to a steering wheel through the transmission shaft, so that transmission of vibration and noise is reduced, and comfort is improved. And the limiting shaft is matched with the limiting hole to play a role in protecting the elastic block. And assembly is convenient, structural reliability is high, and manufacturing cost is low.

    本发明涉及一种拖拉机转向管柱传动轴缓冲装置和转向管柱,涉及农用机械领域,包括装配支撑组件、限位支撑板、弹性块、至少两个限位轴和至少两个连接轴,装配支撑组件具有至少两个限位孔,连接轴的一端与装配支撑组件固定连接,另一端从弹性块的一侧穿过弹性块并连接固定,至少两个限位轴与至少两个限位孔一一对应设置,限位轴的一端与限位支撑板固定连接,另一端从弹性块的另一侧穿过弹性块和对应的限位孔。本发明的有益效果是:弹性块可减少转向器内部的冲击通过传动轴传递到方向盘,从而减小振动和噪声的传递,提高舒适性。限位轴与限位孔配合,起到保护弹性块的作用。并且装配方便,结构可靠性高,制造成本低。
