Description

AN ARRANGEMENT FOR MOUNTING A SUPPORT CROSSBEAM BETWEEN A FIRST MEMBER AND AN OPPOSING SECOND MEMBER OF A VEHICLE TECHNICAL FIELD The invention relates to an arrangement for mounting a support crossbeam between a first member and an opposing second member of a vehicle according to the preamble of claim 1 . The invention also relates to a vehicle.
BACKGROUND ART Vehicles such as trucks are provided with suspension systems comprising spring elements. Such spring elements are fastened by means of spring fastening members attached to the longitudinal beams of the vehicle frame.
In order to increase stability it may be desired to attach a crossbeam between such spring fastening members. It is however not always necessary and attachment of such a support crossbeam increases assembly time and takes up additional weight. Different solutions for thus mounting a crossbeam are known. EP1086836, for example, discloses an arrangement for mounting of a support crossbeam between spring fastening members.
In certain countries/regions it may be a requirement. For such situations retrofitting is the most suitable solution. However mounting a crossbeam afterwards takes time and usually requires extra inserts due to tolerances.
There is thus a need to improve mounting of a support crossbeam between a first member and an opposing second member of a vehicle.
OBJECTS OF THE INVENTION An object of the present invention is to provide arrangement for mounting a support crossbeam between a first member and an opposing second member of a vehicle which facilitates retrofit of such a crossbeam.
