Torsion bar type long-stroke adjustable suspension

The utility model provides a torsion bar type long-stroke adjustable suspension which is used for a vehicle and comprises a wheel assembly (6). A wheel axle of the wheel assembly is connected with theguide stand column (2); a rack is arranged on the side wall of the guide stand column. The rack is meshed with a gear piece in the guide rail seat (1); a gear piece in the guide rail seat (1) is connected with a worm wheel of the worm and gear transmission mechanism (4) through an elastic torsion bar (3); a worm of the worm and gear transmission mechanism (4) is driven by a motor (5) to rotate, and the worm and gear transmission mechanism drives a guide rail base to vertically ascend and descend at a rack of the guide stand column through a torsion bar. The utility model has the advantages ofsimple structure and long adjustable stroke, and can realize full-stroke resilience force adjustability. 本实用新型提出一种扭杆式长行程可调悬架，用于车辆，所述悬架包括车轮总成（6）；所述车轮总成的车轮轮轴与导向立柱（2）相连；所述导向立柱的侧壁处设有齿条；所述齿条与导轨座（1）内的齿轮件啮合；所述导轨座（1）内的齿轮件经弹性扭杆（3）与蜗轮蜗
