The invention provides a rescue vehicle traction rod device with adjustable buffer strength, which is characterized by comprising a traction connecting rod, a traction rod and a buffer device, the traction parts are arranged at the two ends of the traction connecting rod, each traction part further comprises a traction sleeve, a buffer function unit is arranged in a sleeve seat of the sleeve, the axial length d of the buffer function unit is smaller than the axial length D of the sleeve seat, and D-d is larger than or equal to 50 mm and smaller than or equal to 100 mm. The length of the buffer rod can be adjusted through the gap between the buffer function units, and installation of the buffer rod is facilitated. And the type and buffering strength of the buffering function unit can be adjusted according to different traction working conditions, peak traction force transmitted by the traction rod is reduced, smoothness in the traction process is enhanced, and the service life of the traction rod is prolonged.

    本发明提供了一种缓冲强度可调式救援车牵引杆装置,其特征在于,所述装置包括:牵引连杆;牵引部,设置于所述牵引连杆两端,所述牵引部进一步包括:牵引套筒,一缓冲功能单元设于所述套筒的套筒座内,所述缓冲功能单元的轴向长度d小于套筒座的轴向长度D,且:50mm≤D‑d≤100mm。本发明可以利用缓冲功能单元的间隙,调节缓冲杆的长度,便于缓冲杆的安装。并可以根据不同的牵引工况调节缓冲功能单元的类型与缓冲强度,减少牵引杆传递的峰值牵引力,增强在牵引过程中的平顺性,提高牵引杆的寿命。
