Problems solved by technology

[0003] The known solution has the disadvantage that the combination of sporty and comfortable properties of the chassis often leads to opposite behavior and is therefore not possible
The previously proposed solution of a single spring steel solution for a complex valve arrangement varying between comfort and sport settings constitutes a possible, but still unimpressive, range of variation possibilities. satisfactory solution

Embodiment Construction

[0033] figure 1 A chassis arrangement 10 according to the invention is shown which is equipped with a pneumatic suspension system 20 . The comfort function of the pneumatic suspension system 20 is provided by a pneumatic spring chamber 30 which may be pressurized with compressed air to provide spring comfort.

[0034] In order to be able to provide switching according to the invention between steel spring chassis properties and pneumatic spring chassis properties, a mechanical spring arrangement 40 in the form of a helical spring is arranged in the pneumatic chamber 30 as a steel spring. The mechanical spring device 40 has two connection sections 42 and 44 , which are supported at the top and bottom on corresponding countersections 32 and 34 of the pneumatic chamber 30 . In this case it can already be seen that the two opposing sections 32 and 34 are provided in each case with a dedicated transition section 50 which each has a transition space 52 . The switching spaces 52 ea...

Abstract

A chassis device (10) for a suspension system of a vehicle wheel suspension (110) for a chassis (100), the chassis device having a pneumatic suspension system (20) with a first connecting section (42) and with a second connecting section (44) arranged in the pneumatic spring chamber (30), and a second spring section (30), the first connecting section being supported on a first opposing section (32) of the pneumatic spring chamber (30) supported by a second section of the pneumatic spring chamber wherein at least one of the two opposing sections (32, 34) has a transition section (50) designed to change the position of the connection section (42, 44).

Description

technical field [0001] The invention relates to a chassis arrangement for a suspension system of a vehicle chassis wheel suspension and to a method for changing the chassis properties of a vehicle chassis. Background technique [0002] As is well known, vehicles are equipped with different chassis depending on their use. Specifically, two usage differences are encountered at this point. First, there are vehicles or drivers who place a high priority on comfortable driving. Second, there are drivers or vehicles that place a high priority on sporty driving. These two fundamental usage differences, which can be designated as "comfort" or "sport", differ in particular in the area of ​​the chassis by the selection of the corresponding suspension system arrangement or chassis arrangement. Comfort vehicles are often equipped with a pneumatic suspension, which makes it possible to provide the vehicle with particularly comfortable suspension comfort. Sports vehicles are often equi...
