However, since a certain signal processing time is required for this, the suspension unit is adapted to the deflection due to the suspension unit only after a certain time (thus delayed in time with respect to driving over a protrusion).

Embodiment Construction

[0047] Figure 1A A utility vehicle 1 is shown having a body floor 2 on which a first axle 3 and a second axle 4 are arranged. Furthermore, the first wheel 11 is arranged on the first axle 3 and the second wheel 12 is arranged on the second axle 4 . Naturally, at least two wheels are arranged on each axle, wherein in this schematic side view only one wheel 11 , 12 can be seen on each axle 3 , 4 . The first axle 3 and the second axle 4 are arranged to extend in the width direction B here. The utility vehicle 1 is currently moving forward in the longitudinal direction L at a constant speed v.

[0048] Figure 1A Also shown is a situation in which the utility vehicle 1 rides on the protrusion 8 via only the first axle 3 , in particular the first wheels 11 . The force or deflection 13 of the first axle 3 is detected by the sensor 9 and transmitted to the control unit 14 . This transmission can be done by wire or wirelessly.

[0049] After driving on the protrusion 8 , the util...

Abstract

A suspension unit for a utility vehicle, the suspension unit including a control unit, wherein the utility vehicle has a body floor, a first axle and a second axle are connected to the body floor, wherein the utility vehicle includes a suspension device capable of being relative to the body floor Suspended at least one vehicle seat and / or vehicle cab, wherein the vehicle seat and / or vehicle cab are arranged substantially above the second axle in the vertical direction, wherein the first axle is used to travel on the protrusion , the deflection value of the first axle caused by the disturbance can be determined by at least one sensor, wherein the suspension of the vehicle seat and / or the vehicle cab can be changed by the control unit before or while driving on the disturbance with the second axle .

Description

technical field [0001] The invention relates to a suspension unit comprising a control unit for a utility vehicle, wherein the utility vehicle has a body floor to which a first axle and a second axle are connected, wherein the utility vehicle comprises a At least one vehicle seat and / or vehicle cab suspended from the body floor, wherein the vehicle seat and / or the vehicle cab are arranged substantially above the second axle, viewed in the vertical direction. Background technique [0002] Suspension units are known from the prior art, in which the suspension and / or damping of the suspension unit is varied as a function of detected sensor data. In this case, the sensor is arranged in the vicinity of the vehicle seat in order to thus be able to determine the influence of external influences on the vehicle seat, for example when driving over a protrusion. Until now, however, it has been possible only to react to already-proceeding movements of the vehicle seat or the vehicle ca...
