Torsion bar type long-stroke adjustable suspension

The invention provides a torsion bar type long-stroke adjustable suspension for vehicles. The torsion bar type long-stroke adjustable suspension comprises a wheel assembly (6); a wheel axle of the wheel assembly is connected with a guide pillar (2); racks are arranged on the side wall of the guide pillar; the racks mesh with a gear part in a guide rail seat (1); the gear part inside the guide railseat (1) is connected with a worm wheel of a worm wheel and worm transmission mechanism (4) through an elastic torsion bar (3); a worm of the worm wheel and worm transmission mechanism (4) is drivento rotate by a motor (5); and the worm wheel and worm transmission mechanism drives the guide rail seat to rise and fall vertically at the rack position of the guide pillar through the torsion bar. According to the torsion bar type long-stroke adjustable suspension, the structure is simple, the adjustable stroke is long, and adjustable resilience of the whole stroke can be realized. 本发明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
