The present invention relates to an arrangement of measurement devices on a semitrailer motor vehicle having a tractive unit, a semitrailer unit, and a fifth wheel fastened to the tractive unit. The measuring arrangement includes a support structure for the fifth wheel and measurement devices for measuring forces arising between the semitrailer and the tractive unit attached to the support structure. The measurement devices preferably measure acceleration, tractive or braking forces and/or the weight of the semitrailer.

Arrangement of measuring devices on a semitrailer motor vehicle

The present invention relates to an arrangement of measuring devices on a semitrailer motor vehicle having a tractive unit, a semitrailer unit and a fifth wheel fastened to the tractive unit. An intermediate plate is disposed between the fifth wheel, the tractive unit and the semitrailer and is connected to the semitrailer. Measuring devices are disposed on the intermediate plate for measuring acceleration, tractive or braking forces and for measuring the weight of the semitrailer. The measured values are used to influence and improve the driving behavior of the semitrailer motor vehicle.

The present invention relates to the arrangement of measuring devices on a semitrailer motor vehicle having a tractive unit, a semitrailer unit and a fifth wheel fastened to the tractive unit. The measuring devices(s) in each arrangement are disposed between the fifth wheel and the semitrailer. In one embodiment, a force sensor for measuring tractive and acceleration forces is disposed on a coupling claw forming part of a locking mechanism associated with the fifth wheel. In the same embodiment, a measuring device for measuring impact and pressure forces arising during braking is operationally connected to a movably mounted contact part forming part of the locking mechanism. Alternative embodiments of the present invention showing different measuring arrangements are also disclosed.

The present invention relates to an arrangement of measuring devices on a semitrailer motor vehicle having a tractive unit, a semitrailer unit and a fifth wheel fastened to the tractive unit. The fifth wheel has a coupling plate which is pivotally disposed on a support structure such as a support block. The measuring arrangement includes measuring devices for measuring acceleration, tractive or braking forces which arise in the fifth wheel of the tractive unit. In the various embodiments disclosed herein, the measuring devices are incorporated into the support structure. If desired, the measuring devices may also include devices for effecting measurement of the weight of the semitrailer. The measured values are converted in an evaluation device into appropriate control commands for influencing the driving behavior of the semitrailer motor vehicle.
