Abstract

A chassis arrangement (10), in particular for utility vehicles (1), with at least one axle (3) that extends transverse to the travel direction and carries wheels (4). Movement of the axle (3) is damped by vibration dampers (11) provided with end sections (15), and with at least one stabilizer assembly (12) that has two longitudinally extending sections (13) and a transverse section (14) that connects the longitudinally extending sections. An end section (15) of the vibration damper (11) is held directly on and is connected to the stabilizer assembly (12) on an extension (16, 17) of the transversely orientated section (14) beyond the longitudinal section (13).

First claim

The invention claimed is:

1. A chassis arrangement, for a utility vehicle, with at least one axle extending transversely to a travel direction and carrying wheels;
movement of the axle being damped by vibration dampers, each of the dampers having one end connected to a frame of the vehicle and having an opposite lower end;
at least one stabilizer assembly pivotally connected to the frame of the vehicle comprising two longitudinally extending sections and a transversely orientated tubular, non-linear section, the transversely oriented tubular, non-linear section having axially opposite ends, the ends of the transversely orientated tubular, non-linear section are connected to a first end of the respective two longitudinally extending sections, the lower ends of the vibration dampers being held directly on a respective extension of the transversely orientated tubular, non-linear section, the extensions comprising an outwardly facing pin and a separate flange element which are received at least partially into the ends of the transversely orientated tubular, non-linear section and extend transversely outside the longitudinally extending sections;
the axle being spring loaded by air suspensions;
the lower ends of the vibration dampers being directly connected to the two longitudinally extending sections at a location between where the at the least one stabilizer assembly is pivotally connected to the frame of the vehicle and the axle; and
two air suspensions are supported on each of the at least one axle, on each transverse side of the vehicle, and transversely inside the longitudinally extending sections such that the dampers are located with respect to air suspensions on opposite transverse sides of the longitudinally extending sections, and the two air suspensions are provided in a space saving arrangement in the travel direction over the axle.

2. The chassis arrangement according to claim 1 , wherein the opposite ends of the transversely orientated tubular, non-linear section each have an opening, and the flange element is at least partially inserted into the opening of the transversely oriented tubular, non-linear section of the stabilizer assembly such that the flange element is located transversely between the longitudinally extending section and the vibration damper.

3. The chassis arrangement according to claim 1 , wherein the lower end of the vibration damper has an eye which is held on the extension of a transversely orientated tubular, non-linear element of the stabilizer assembl.

4. A utility vehicle (UV), with at least one chassis arrangement having at least one axle extending transversely to a travel direction and carrying wheels, and movement of the axle being damped by vibration dampers provided with lower ends;
at least one stabilizer assembly pivotally connected to the frame of the vehicle comprising two longitudinally extending sections and a transversely orientated tubular, non-linear section, the transversely oriented tubular, non-linear section having axially opposite ends, the ends of the transversely orientated tubular, non-linear section are connected to an end of the respective two longitudinally extending sections, the lower ends of the vibration dampers being held directly on a respective extension of the transversely orientated tubular, non-linear section, the extensions comprising an outwardly facing pin and a separate flange element which are received in the ends of the transversely orientated tubular, non-linear section and extend transversely outside the longitudinally extending sections;
the axle being spring loaded by air suspensions;
the lower ends of the vibration dampers being directly connected to the two longitudinally extending sections at a location between where the at the least one stabilizer assembly is pivotably connected to the frame of the vehicle and the axle; and
two air suspensions are supported on the axle, on each transverse side of the vehicle, and transversely inside the longitudinally extending sections such that the dampers are located with respect to air suspensions on opposite transverse sides of the longitudinally extending sections, and the two air suspensions are provided in a space saving arrangement in the travel direction over the axle.

5. A chassis arrangement for a utility vehicle having at least one axle carrying wheels and extending transverse to a travel direction of the vehicle, the travel direction defining a longitudinal axis;
vertical movement of the axle being damped by a vibration damper provided with opposite upper and lower ends,
at least one stabilizer assembly pivotally connected to the frame of the vehicle comprising two longitudinally extending sections and a transversely orientated tubular non-linear element that is connected to axle-side ends of the longitudinally extending sections such that the lower end of the vibration damper is held directly on and connected to the stabilizer assembly on an extension of the transversely orientated tubular non-linear element by an outwardly facing pin that is received within laterally open ends of the transversely oriented tubular non-linear element such that the vibration damper is connected to the stabilizer assembly laterally outside the longitudinally extending section and the lower ends of the vibration dampers are directly connected to the two longitudinally extending sections at a location between where the at the least one stabilizer assembly is pivotally connected to the frame of the vehicle and the axle;
the axle being spring loaded by air suspensions; and
two air suspensions are provided on the axle on each transverse side of the vehicle such that the two air suspensions are connected to the stabilizer assembly laterally inside the longitudinally extending section.
