The invention discloses a two-stage rigidity shock absorber, a vehicle body front suspension and a vehicle body rear suspension, and relates to the technical field of automobile parts. The two-stage rigidity shock absorber comprises a damping spring, wherein a double-rigidity spring is arranged outside the damping spring in a sleeving manner; the double-rigidity spring is divided into a first rigidity section and a second rigidity section; and the screw pitch of the first rigidity section is smaller than that of the second rigidity section. The two-stage rigidity shock absorber can meet the shock absorption requirements of all-weather all-road-condition vehicles, the shock absorber and a cab are prevented from being damaged, the service lives of a piston and an oil seal of the shock absorber are prolonged, and the comfort of a driver is improved.

    本发明公开了一种二级刚度减震器、车身前悬置及车身后悬置,涉及汽车配件技术领域,其包括阻尼弹簧,阻尼弹簧外套设有双刚度弹簧,该双刚度弹簧分为第一刚度段和第二刚度段,且第一刚度段的螺距小于第二刚度段的螺距。本发明可以适应全天候全路况的车辆减震需求,防止减震器及驾驶室损坏,并提高了减震器活塞、油封的使用寿命,以及驾驶员的舒适性。
