Definitions

  • the present invention relates to a method for testing and a test apparatus adapted for testing, and in particular for mechanical testing of the relative fastening between the different vehicle components and the fastening of same to the vehicle's chassis.
  • the invention accordingly relates to testing and searching for wear in wheel suspensions and/or chassis of vehicles, and also on connections and pull rods between tractor units and trailers in juggernauts.
  • a test apparatus previously known from said design registration and from practical use, includes an apparatus provided with two test plates which hydraulically or pneumatically may be moved horizontally.
  • a test apparatus previously known from said design registration and from practical use, includes an apparatus provided with two test plates which hydraulically or pneumatically may be moved horizontally.
  • test apparatus When the applicant's previously known test apparatus was used, one single operator could move the wheels forward and backwards horizontally while regarding the components of the car looking for undesired play and defects in connections. However, the apparatus was not able to test wear due to vertical movements, and could not test or check load dependent brake systems on heavier vehicles.
  • a moveable jack 5 is also shown.
  • this jack is not used to obtain any vertical movement of the wheels, only for releasing the weight of the vehicle. Accordingly the chassis of the vehicle is relieved while the wheels are moved horizontally, which in the reality gives a test situation quite different from the conditions during use of the car.
  • German patent De 3.040.355 C2 it is also known to provide a test apparatus for motor vehicles, using separate self -powered and brakeable belt driven units for each wheel, in which each belt unit is fastened to mutually perpendiculary arranged bearings, so that resiprocating movements along three orthogonal axes may be superimposed on the movements of the belt itself.
  • test apparatus shown in DE 3.040.355 C2 is not suitable for testing of heavy vehicles, as each belt unit is rather vulnerable of heavy mass forces, and in addition it is not suited for transmitting abrupt movements in a precise manner to a heavy vehicle, as each belt unit is somewhat resilient and flexible, which also renders transmission of fast movements with long strokes to heavy vehicles impossible.
  • the shown apparatus is in addition rather complicated as it includes a large number of relatively movable components exposed to hard wear during use. Due to the same reasons this apparatus will be rather expensive, it will require much maintenance and a large amount of different reserve parts must be kept available. These conditions probably also contribute to the fact that this apparatus is not found in practical use.
  • the object of the present invention thus is to provide a method for testing and a test apparatus which in particular is adapted to check the function of the wheel suspensions, the brakes and the spring systems of heavier vehicles .
  • a further object of the present invention is to provide a method and a test apparatus for testing and detecting vertical as well as horizontal local wear and excisting deficiencies in wheel suspensions, together with a testing of chock absorbers and the fastening points for same.
  • a further object of the present invention is to provide a method and a test apparatus which make it possible to simulate different road conditions and different load of the vehicle, and accomplish this testing of valves and level regulations of heavier vehicles without using an assortment of movable, heavy loads. Further it is an object of the present invention to provide a method according to which a comprehensive testing of heavier vehicles will be particular easy and practical and may be undertaken by means of one single test apparatus which in addition may be monitored by one single operator, as the operator may move freely around and below the vehicle while he, by simple manual actions, controls different and strong forces, e.g. by operating one joystick and a few switches .
  • test apparatus which may be combined with previously known test apparatus, to give a new test apparatus with which both horizontal and vertical forces acting on each single or on different wheel suspensions of each vehicle, may be controlled in one single operation. And at the same time additional but different tests, e.g. testing of brakes and of the wheel's toe-in and the parallalism of the drive shafts may be carried out by using the same test apparatus .
  • Fig. 1 shows a test apparatus according to the present invention provided with two test plates
  • Fig. 2 shows the principle of the present invention used on a wheel shaft while the wheels are suspended at different levels, shown by means of a cross section of the apparatus at the test plate position

  • the same reference numbers are used on all the figures when found appropriate, that some of the design details are omitted in the figures to avoid crowded figures, and that the scale not necessarily is the same in the different figures and not for different details in one single figure; as the principle of the invention and the elements required to explain same, is deemed to be substantial .
  • the test apparatus 10 comprises two test plates 1,2 adapted to be moved individually in vertical direction.
  • the test plates 1,2 may be moved both upwards and downwards from their initial positions, and this movement is obtained as the plates are exposed to forces by means of a conventional power transmission system, not shown on the figure to avoid crowding of same.
  • the power transmission system may be of a mechanical, hydraulical, pneumatical or electromechanical system, or may comprise a combination of two or more such systems.
  • a hydraulic system often will be preferred, as hydraulic equipment is used on most control and repair plants for vehicles.
  • the selection of a power transmission system is however, only a practical question, and any system which is used will be within the scope of this invention.
  • test plates 1 and 2 may be moved up and/or down from an initial position within certain predetermined limits. Normally the upward directed movement is obtained by means of a power system, such as hydraulic, while movement downwards takes place as a free or attenuated fall movement. However, also the downward movement may, if desired be undertaken with control from a power operated system.

  • the cable 15 normally is an electric multiconductor and the control unit 13 comprises the required interfaces, including e.g. relays and valves, for powering of the different power units (not shown) used to move the test plates 1,2.
  • the power units may e.g. comprise hydraulic cylinders and pistons, including the required connections. People skilled within this technical field will easily understand how the equipment may be built to ensure that an operator by moving a sliding switch on the portable operating unit 14, may cause an upward or downward movement of the test plates 1 and 2.
  • the control unit 13 may be provided with a switch 16 which changes the signals to one of the test plates so that the plates always move in opposite directions, or in such a manner that one of the plates will stay quiet.

  • the wheels 3,4 may be adjusted to different levels, which leads to a tilting position of the vehicle located on the test apparatus so that the wheel shaft 20 will be askew, which again gives the possibility for testing of many different connections in the wheel suspension unit, and the function of air spring couplings as well as movements of the chassis or frame.

Abstract

Technique et dispositif de test permettant de contrôler des véhicules, notamment de vérifier les suspensions de roues, les suspensions de train avant, les freins et/ou les éléments du châssis, afin de détecter des points d'usure ou des défauts locaux. Le dispositif de test comprend au moins une plaque de test (1, 2) sur laquelle il est possible de placer une roue ou un groupe de roues (3, 4), et qui est conçue pour être déplacée d'une manière contrôlée pendant que le véhicule est positionné de façon qu'au moins une roue ou un groupe de roues (3, 4) se trouve sur la plaque de test correspondante (1, 2). La technique peut être mise en oeuvre par un seul opérateur placé à l'endroit convenable, qui vérifie visuellement la zone à contrôler et/ou la touche pendant qu'elle se déplace de la manière désirée. Le dispositif est caractérisé par le fait que chaque plaque de test (1, 2) est conçue pour être déplacée en direction verticale à une vitesse suffisamment élevée et avec une course suffisamment longue pour que la suspension de roue correspondante soit exposée à des forces similaires à celles auxquelles elle est exposée durant l'utilisation normale du véhicule. Des détecteurs peuvent être utilisés pour contrôler les déplacements relatifs entre les différents composants du véhicule. Le dispositif peut également être utilisé pour d'autres tests, par exemple pour tester les freins et l'alignement et le parallélisme des arbres de transmission faisant partie d'une unité remorque et caravane complète. Tous les tests nécessaires à un véhicule peuvent être effectués par un seul dispositif.
