Definitions

  • the invention relates to a rolling test stand for tires or rims with a mounting spindle for a
  • Vehicle wheel the spindle bearing of which is attached to a slide which can be moved radially to a running drum, and with a force measuring device for at least the radial contact forces, a measuring element being arranged between the spindle bearing and the slide, which has separate deformation bodies for radial forces and axial forces acting on the spindle bearing.
  • Roll-off test benches of this type are used to test tires or rims for motor vehicles under conditions which are close to the company and in some cases considerably more. Radial contact forces and transverse forces, essentially axially directed to the spindle bearing, must be measured.
  • the forces measured in this way are displayed after preparation of the measured values and / or are used to calculate further parameters.
  • the measured forces can be used to regulate the contact or lateral force.
  • Rims are not directly measured the forces introduced on the mounting spindle. Rather, they are forces occurring between the slide and the machine frame are measured, for example a load cell being arranged between the cylinder or the spindle as a force-introducing part and the slide. It is also known to measure only the hydraulic pressure in the hydraulic cylinder acting on the slide in order to determine the applied radial force or lateral force therefrom. However, the forces measured in this way are falsified by friction forces, temperature influences and other factors that occur on the slide. The force measurement is therefore inaccurate, so that this type of test bench cannot be certified.
  • Measuring device is therefore relatively complex and takes up a lot of space.
  • the object of the invention is therefore to design a rolling test stand of the type mentioned at the outset in such a way that it has a simple and robust construction and is therefore particularly suitable as a rim test stand.
  • the measuring element has as deformation body at least one bending web deformable only by radial forces and at least one bending web deformable only by axial forces, and that the bending webs carry strain measuring elements which are connected to an evaluation circuit of the force measuring device.
  • the measuring element arranged between the spindle bearing and the slide can be designed with simple constructional measures so that it is suitable for absorbing high forces, whereby a separate detection of radial forces and axial forces is made possible. Neither the mass of the slide nor the frictional forces acting on the slide or similar factors influence the measurement.
  • bending webs as the deformation body enables on the one hand the absorption of high forces to support the spindle bearing; on the other hand, the bending webs equipped with strain gauges form sufficiently sensitive measuring elements that deliver usable measuring signals directly in the evaluation circuit.
  • the measuring element preferably consists of two arranged parallel to one another, on the one hand with the
  • Each measuring plate is divided by a family of bending webs that can be deformed in the radial direction and a family of bending webs that can be deformed in the axial direction into three plate sections that are movable relative to one another.
  • the two measuring plates are comparatively easy to manufacture, compact components, which on the one hand enable the necessary parallel guidance of the spindle bearing in the radial and axial direction (in each case with respect to the spindle axis) and at the same time form the measuring elements. Separate parallel guides and separate measuring elements can therefore be dispensed with.
  • the invention is based on one
  • FIG. 1 is a rolling test stand for tires or rims in a plan view
  • Fig. 2 is an enlarged view in the direction of arrow II in Fig. 1 and
  • Fig. 3 is an enlarged view of one of the measuring plates used in the rolling test stand according to FIGS. 1 and 2.
  • the rolling test stand shown in FIGS. 1 and 2 as an exemplary embodiment of the invention has a running drum 3 mounted in a machine frame 1 in drum bearings 2, on the cylindrical peripheral surface 4 of which a vehicle wheel 5 rolls, which consists of a rim 6 and a pneumatic tire 7.
  • the rolling test bench is used, for example, for tire testing. Instead, the rolling test bench can also be used as a rim test bench or as a tire uniformity testing machine.
  • the vehicle wheel 5 is received in a receiving spindle 8 which is rotatably mounted in a spindle bearing 9.
  • the spindle bearing 9 is attached to a steering bracket 11 via measuring plates 10, which will be described in more detail later, and which can be adjusted on a carriage 12 about a pivot axis 13 directed radially onto the running drum 3.
  • an adjusting cylinder 14 which is supported on the slide 12, articulates on the steering bracket 11.
  • the carriage 12 is loaded by a force
  • the two parallel measuring plates 10, which connect the spindle bearing 9 to the steering bracket 11 are each by three parallel bending webs 15, 16 and 17, which extend in the radial direction, and by three in Bending webs 18, 19 and 20 which extend in the axial direction are subdivided into three plate sections 10a, 10b and 10c which are movable relative to one another.
  • the two plate sections 10c are screwed onto the steering bracket 11.
  • the middle plate section 10b is guided so as to be movable in the radial direction while deforming the bending webs 18, 19 and 20.
  • the bending webs are preferably made in one piece with the plate sections 10a, 10b and 10c and therefore form bending beams clamped on both sides.
  • the middle bending web 16 or 19 carries strain gauges 21 or 22 applied as strain measuring elements on both sides of the web ends, which are connected in a bridge circuit to an evaluation circuit (not shown) of a force measuring device.
  • a bending web 16 or 19 of each family of parallel bending webs 15, 16 and 17 or 18, 19 and 20 thus forms a deformation element of a measuring element.
  • the running drum 3 is determined from the deformation of the bending web 19. By swiveling the steering bracket 11 cornering forces of the vehicle wheel 5 can be caused. These axial forces occurring in the axial direction of the receiving spindle 8 are determined from the deformation of the bending web 16.

Abstract

Banc d'essai de roulement pour pneus et jantes, qui comporte une broche réceptrice (8) pour une roue (5) de véhicule à moteur, le palier (9) de ladite roue étant monté sur un chariot (12) pouvant être déplacé radialement par rapport à un tambour de roulement (3). Un dispositif de mesure de forces possède un élément de mesure (10) placé entre le palier (9) de broche et le chariot (12). Ledit élément de mesure, conçu en tant que corps de déformation, comporte au moins une barrette de flexion (19) déformable uniquement sous l'effet de forces radiales et au moins une barrette de flexion (16) déformable uniquement sous l'effet de forces axiales. Lesdites barrettes de flexion (16, 19) portent des éléments de mesure d'extension (21, 22) qui sont reliés à un circuit d'évaluation du dispositif de mesure de forces.
