GAVRILOV ALEKSEI V

The invention relates to a suspension for motor vehicles, having controllable ground clearance and comprising a helical spring (1) having a control apparatus (2) which is fastened to the body of the vehicle and is rotatably arranged, preferably by means of a gear stage driven by an electric motor. According to the invention, the control apparatus (2) is designed as a shaped nut which is screwed directly onto the coils of the preferably cylindrical helical spring (1) and has rolling elements which are located along the helical curve and are connected to the coils of the helical spring, whereinthe control apparatus (2) can be secured completely to the helical spring (1) and is movable relative thereto. The suspension for motor vehicles ensures increased rigidity of the suspension when reducing ground clearance, reduced rigidity of the suspension when increasing ground clearance, and the possibility to install a telescoping damper within the helical spring without blocking access to thetop fastening point thereof.

本发明涉及一种具有可控底盘间隙和刚度的机动车辆的悬架，其包括螺旋弹簧(1)，该螺旋弹簧具有控制装置(2)，该控制装置被固定至车辆的车身并且优选地借助于由电马达驱动的传动级可旋转地定位。控制装置(2)被实现为成形螺母，其直接旋拧在优选为圆柱形的螺旋弹簧(1)的线圈上，并具有沿螺旋线定位并与螺旋弹簧的线圈相连接的辊体；相对于螺旋弹簧，控制装置(2)完全可移动并可固定在其上。机动车辆的悬架确保了底盘间隙减小时悬架的刚度提高，底盘间隙增大时悬架的刚度减小，以及在不阻碍对其上部固定点的触及的情况下在螺旋弹簧内部内置伸缩阻尼器的可能性。
