Problems solved by technology

If the spring and the damper are supported separately on the rod guide, this leads to construction space disadvantages, since the two elements must lie on the line of action of the rod guide and cannot be arranged offset relative to the line of action
[0003] The disadvantage of the known solution is that a relatively large space is required when the spring unit is separated from the shock absorber unit in order to arrange the spring unit and the shock absorber unit in the area of ​​the axle arrangement and especially to arrange the spring unit and the shock absorber unit. The vibrator unit is connected to the corresponding load-bearing guide rod in a force-transmitting manner
However, this results in an increased space requirement for the axle arrangement in the transverse direction compared to a combined spring-damper unit
The increased space requirement of the axle arrangement leads to a reduction in the space possibilities between the wheel carriers or to a The width of the vehicle is increased

Embodiment Construction

[0025] figure 1 and 2 A first embodiment of an axle arrangement 10 is shown. The axle arrangement is here substantially equipped with a first link 30 and a second link 40 , which extend in a force-transmitting manner between the wheel carrier 20 and the body 100 . Here, the wheel 200 is connected and rotatably fixed to the wheel bracket 20 . For retraction and deployment in a damped manner, a spring unit 60 and a shock absorber unit 70 separate therefrom are provided. In order to be able to ensure the transmission of forces to the spring unit 60 and the damper unit 70 , the axle arrangement 10 is here designed as a multi-link system with support links 50 . The support link 50 also extends in a force-transmitting manner between the wheel carrier 20 and the body 100 .

[0026] like figure 1 and 2 As clearly shown, the carrier link 20 is connected in a force-transmitting manner to the wheel carrier 20 via the carrier section 52 . Now if in the lateral direction QR of the v...

Abstract

An axle device for the connection of a wheel to the body of a vehicle, having a wheel carrier for the fastening of the wheel, a first link and a second link for force-transmitting connection to the body, which links are both connected to the wheel carrier, furthermore having a supporting link with a carrier portion, which is connected to the wheel carrier, and with a body portion for force-transmitting connection to the body. The supporting link has a spring portion or supporting a spring unit and a damper portion for supporting a damper unit, which spring portion and damper portion are spacedapart from each other in the direction of travel of the body. The body portion has a torsion support portion with fastening freedom in the direction of travel and in the transverse direction of the body and with fastening stiffness in the vertical direction of the body.

Description

technical field [0001] The invention relates to an axle arrangement for joining the wheels of a vehicle to a vehicle body and to a vehicle having a body with at least two such axle arrangements at an axle. Background technique [0002] The invention deals with an axle arrangement as it is used in a vehicle with independent wheel suspension. The forces acting on the wheel must be supported in all degrees of freedom. This usually takes place on the one hand via chassis links, which may possibly be provided with active adjustment elements, for example for steering. On the other hand, the forces acting on the wheels are supported via the spring-damper unit. This is used to improve comfort, safety and stability. The spring-damper unit can either be embodied coaxially or the spring and damper can be separated from each other. A separate link serves to predetermine a defined relative movement of the wheel between the wheel carrier and the body during retraction and deployment. ...
