Embodiment Construction

[0011] figure 1 The shown spring frame is used to support the coil spring 1, wherein in this embodiment, as shown in the figure, one end of the coil spring 1 is supported on the spring seat 2. At the inner center of the coil spring 1, there is a A damper 3 of a piston rod 5 which is inserted axially pivotably into the damper sleeve 4. This damper can form a structurally predetermined damping. Of course, dampers with variable damping forces can also be used. The connection of the wheel suspension is realized via a flange not further shown in the bottom area. The connection of the piston rod 5 is realized in a known manner via a component 6 of the body structure. For this purpose, the piston rod 5 is connected by means of a nut 7 is screwed onto an angle-elastic (winkelastish) and shock-elastic connecting piece 8. This is in turn operatively connected to the body structure component 6 by means of bolts 9. The spring carrier works together with an adjustment device 10, which is ...

Abstract

The invention provides a vehicle running mechanism provided with a tensioned helical spring frame which supports and is arranged between two spring seats and a cushioning device. A piston rod and / or apart of a cushioning device casing pipe is arranged inside the helical springs. At least one spring seat can move in the axial direction through an annular motor consisting of a stator and a rotor and a driver element comprising a transmission gear consisting of a lead screw nut and a lead screw. One end of a lead screw nut and at least one part of the lead screw is arranged in the helical springs in the radial direction; and the other end is radially arranged in the area, into which the annular motor extends in the axial direction.

Description

technical field [0001] The invention relates to a vehicle running gear with a spring carrier for supporting a helical spring tensioned between two spring seats and a damping device, wherein a part of the piston rod and / or a part of the piston rod are arranged in the helical spring Shock absorber sleeve in which at least one spring seat is axially displaceable by means of a drive unit consisting of a ring-shaped electric motor consisting of a stator and a rotor and a transmission consisting of a spindle and a spindle nut. Background technique [0002] From DE-A 195 10 032, a spring carrier in a vehicle running gear is known, which is used to support a helical spring tensioned between two spring seats and comprises at least one axially movable spring seat and Fastening on the chassis and body structure of vehicles, where the spring seat is positioned axially by means of a drive unit. An electric motor is used here as the drive unit, a transmission being arranged between the m...
