Embodiment Construction

[0027] figure 1 and figure 2 A representation of an independent suspension 1 for a commercial vehicle according to the invention is shown in each case. The independent suspension 1 shown here comprises a steering knuckle 2 with a hub 3 . The steering knuckle 2 is connected to the steering knuckle bracket 5 by means of a kingpin 4 and is mounted rotatably about an axis of rotation A. As shown in FIG. Steering knuckle king pin 4 in figure 2 is shown in a sectional view and can be seen more clearly there. exist figure 1 and figure 2 At its upper end, the steering knuckle kingpin 4 has an eye-shaped fastening section 6 which has a through-cut fastening hole 7 therein, which here is embodied as a bore. Adjacent to this borehole, the steering knuckle kingpin 4 has a cylindrical mounting section 8. In the fastening hole 7 of the steering knuckle kingpin 4 there is at least one bearing 9 which enables a defined vertical deflection of the upper transverse link 10 , 11 fastene...

Abstract

The invention relates to an independent suspension for a commercial vehicle, comprising a steering knuckle, which is arranged on a steering knuckle pin in a rotatable manner about a first rotational axis and which comprises a wheel hub; a steering knuckle carrier, which is connected to the steering knuckle by means of the steering knuckle pin; a vibration damper and a spring element, each of which can be fixed to a fixing element formed on the steering knuckle carrier and to another fixing element of the vehicle body; and at least one upper transverse link and at least one lower transverse link, which are at least indirectly connected to the steering knuckle and to another fixing means of the vehicle body. The upper transverse link is arranged above the steering knuckle carrier in the installed position, and the lower transverse link is arranged below the upper transverse link in the installed position. The invention is characterized in that the upper transverse link is fixed to the steering knuckle pin and is rotatably supported about a second steering knuckle-side rotational axis; the lower transverse link is supported on the steering knuckle carrier in a rotatable manner about a third steering knuckle-side rotational axis of the lower transverse link; and the third steering knuckle-side rotational axis of the lower transverse link is radially spaced from the first rotational axis of the steering knuckle.

Description

technical field [0001] The invention relates to an independent suspension for commercial vehicles. Background technique [0002] For example EP0935537B1 discloses an independent suspension for a motor vehicle having a steering knuckle with a hub, a knuckle bracket, an upper transverse link and a lower transverse link. Specifically, the independent suspension includes: a steering knuckle arranged on a steering knuckle kingpin in a manner capable of rotating around a first rotation axis, the steering knuckle having a hub; a steering knuckle bracket connected to the steering knuckle through the steering knuckle kingpin a shock absorber and a spring element, which can each be fastened on one side to a fastening element formed on the steering knuckle bracket and on the other side to another fastening element of the body; at least one upper part A transverse link and at least one lower transverse link, wherein the transverse link is at least indirectly connected on one side to th...
