Problems solved by technology

However, the essential disadvantage is still the overheating of the supporting structure, since the heat can generate thermal stresses in the supporting structure and / or the lubricant provided in the supporting structure loses its functionality

Embodiment Construction

[0018] figure 1 A sectional view of the wheel suspension is shown as an example of a left-hand drive motor vehicle wheel 1 . Motor vehicle wheel 1 with brake disc 6 is connected to hub 4 in a rotationally fixed manner. The hub 4 is provided with internal teeth 4a, into which a drive shaft, not shown, engages. The wheel hub 4 is mounted rotatably relative to the wheel bearing bracket 2 via a wheel bearing 5 . Arranged on the wheel bearing carrier 2 is a bearing outer ring 8 which forms a radially outer running surface for the rolling bodies of the wheel bearing 5 .

[0019] The wheel bearing carrier 2 is formed in two parts from a first part 2 a and a second part 2 b and projects with arms 7 and 9 into an annular gap X provided between the brake disk 6 and the vehicle wheel 1 . The arms 7 and 9 are dimensioned in such a way that there is an air gap X1 and X2 in each case between the arm and the brake disk 6 or the motor vehicle wheel 1 . In principle, with such an arrangeme...

Abstract

The suspension has a carrier unit provided with a motor vehicle wheel (1) and pivotable around steering axis (S). The carrier unit includes a wheel hub (4), at which the motor vehicle wheel is arranged. A two-piece wheel bearing carrier (2) is equipped with a wheel bearing (5), by which the wheel hub is supported in relation to the wheel bearing carrier. The steering axis is formed in a wheel center plane, and a part (2a) of the wheel bearing carrier is supported in relation to another part (2b) of the wheel bearing carrier and tiltable around the steering axis.

Description

technical field [0001] The invention relates to a wheel suspension for a motor vehicle with the features of the preamble of claim 1 , having a carrier unit for a wheel of the motor vehicle which is pivotable about a steering axis. Background technique [0002] Wheel suspensions with pivotable carrier units are used in particular for steerable motor vehicle wheels and are known in various embodiments. For example, wheel suspensions with double tie rods or McPherson shock struts are known, in which the steering axis is arranged at a relatively large inclination of 12-14 degrees relative to the longitudinal plane of the vehicle , this inclination is also known as the opening angle (Spreizungswinkel). In the described embodiment, since the steering shaft runs at a relatively large distance from the center of the wheel, the forces acting on the wheel through this distance generate a so-called disturbing moment acting on the steering, which is considered to be uncomfortable and ...
