Description
Improvements in and Relating to Apparatus
for and a Method of Determining the Extent
to which a Vehicle has been Loaded
This invention relates to apparatus for and a method of determining the extent to which a vehicle has been loaded and, more especially but not exclusively, concerns apparatus for and a method of comparing the unladen and loaded weights of a vehicle to provide a measure of the extent to which further loading (if any) can be accommodated without exceeding a predetermined laden weight. The invention also concerns apparatus for and a method of enabling a load to be distributed evenly (or otherwise) within or onto a vehicle.
The term "vehicle" is used herein to embrace any carriage or conveyance used on land and includes such vehicles as vans, lorries, trucks, heavy goods vehicles, trailers, farm equipment and railway wagons.
Heavy goods vehicles are subject to certain constraints when using public highways. One such constraint concerns the load which can safely be carried by a given vehicle. This load is determined by the appropriate authority on construction or inspection of the vehicle and is recorded on the vehicle itself. This load, known as the fully laden weight of a vehicle, is expressed as the maximum weight which can be applied through each half-axle of the vehicle to the road surface.
When the load carried by a heavy goods vehicle is believed to be such that the vehicle's laden weight exceeds its permitted fully laden weight, the vehicle is normally escorted to a weighbridge where appropriate measurement of the load applied through each wheel or set of wheels can be effected. However, in many instances an operator of a heavy goods vehicle, for example a furniture removal van, has no way of knowing precisely the weight of a load carried by his vehicle or the manner in which the load is distributed over the chassis floor, and can, therefore, unwittingly exceed the vehicles permitted fully laden weight and face prosecution for doing so.
The present invention sets out to provide means by which an operator can readily ascertain the extent to which a vehicle has been loaded and/or means by which an operator can determine the distribution of the load within the vehicle.
According to the present invention in one aspect there is provided apparatus for indicating the extent and/or manner in which a vehicle has been loaded, the apparatus comprising sensing means supported above one or each axle or half-axle of a vehicle, the or each sensing means being operable to detect variations in the distance between the or each axle or half-axle and the vehicle bed or chassis during loading of the vehicle and to cause a display to be activated indicative of the laden weight of the vehicle.
The or each sensing means may comprise a plurality of individual sensors which are activated sequentially as the distance between the respective axle and the bed or chassis varies during loading of the vehicle, each sensor being coupled electrically to a display unit and operable to cause a signal to be passed to a member of the display when the distance between the axle and the bed or chassis reaches a predetermined value. The display member may comprise a light and/or audible alarm. The sensors may be connected to operate differently coloured lights to provide an effective indication of the load applied to the vehicle chassis.
The individual sensors are preferably spaced in a vertical sense and may be supported on an arm upstanding from the respective vehicle axle (or a member supported thereon) or an arm depending from the undersurface of the vehicle bed or chassis. The sensors are preferably sequentially operated by some form of activating device carried by an arm depending from the undersurface of the vehicle bed or chassis or upstanding from the respective vehicle axle (or a member supported thereon).
Alternatively, the or each sensing means may comprise a tubular housing dependent from the undersurface of the bed or chassis of a vehicle, a slide mounted with the housing and selectively movable downwardly into contact with an axle or half axle of the vehicle (or a member supported on or above the axle), relative movement between the slide and the housing in use of the apparatus effecting sequential switching of sensors coupled electrically to a display unit to indicate the extent and/or manner of loading of the vehicle.
The slide may be driven selectively downwardly by an electric motor, the slide including a switching device which causes the electric motor to be deactivated as the switching device makes contact with the vehicle axle (or a member supported on or above the axle).
The slide may be supported by a line wound onto an output shaft of the electric motor, operation of the motor causing the slide to be moved upwardly or downwardly as required.
The activating device may comprise a light source operable to project a defined beam of light onto the vertical array of individual sensors, each sensor comprising a light activated device including, for example, a fibre optic coupled to transfer light from the light source to effect operation of the display.
Alternatively, the activating device may comprise a plurality of fingers of different length either projecting upwardly from the respective vehicle axle or projecting downwardly from the vehicle bed or chassis, each finger co-operating with a switch or the like to effect operation of the display.
In another aspect, the invention provides a method of determining the extent and/or manner of loading of a vehicle, the method including the steps of sensing variations in the distance extant between an axle or half axle of the vehicle and the undersurface of the vehicle bed or chassis, and producing from the sensed variations a visual display which indicates to the operator the extent to which the vehicle is loaded.
The display may include separate displays for the several sensing means positioned one towards each suspension unit of the vehicle thereby to provide to the operator an indication as to the manner in which the load is distributed within the vehicle.
Means may be provided for detacting whether or not the vehicle bed or chassis lies in a horizontal plane and/or adjusting the sensors to accommodate any difference which may be present.
The invention will now be described by way of example only with reference to the accompanying diagrammatic drawings in which:
Figure 1 is a schematic side view of apparatus in accordance with the invention;
Figure 2 is a section taken along line II-II of
Figure 1;
Figure 3 is a schematic rear view of a heavy goods vehicle showing apparatus in accordance with the invention in place;
Figure 4 is a schematic side view of an alternative device in accordance with the invention;
Figure 5 schematically shows a typical visual display for use with apparatus in accordance with the invention; and
Figure 6 is a side view in section of an alternative apparatus in accordance with the invention.
The load determining device illustrated in Figures 1 and 2 comprises a light source 1 including a light transmitting fibre connected optically to a high intensity light beam source 2 mounted on the vehicle structure. The light source 1 is located within a tubular housing positioned within a through-hole of an upstanding arm 3 mounted on and towards one end of the housing of a vehicle axle 4. Spaced a small distance from light emitting end of the light source 1 is a vertical array of light receivers 5 each comprising a light transmitting fibre connected optically to a converter operable to output an electrical pulse when light is transmitted. The array is carried by an arm 6 suspended from the under surface of the vehicle bed or chassis 7.Each light receiver 5 is mounted within a housing 8 for movement within a guideway 9 such that the position of the housing and therefore the light receiver within the guideway can be varied by means of screws 12 whose heads co-operate with the sides of the guideway to lock the housing at any selected height. The several optic fibres form part of a loom 10.
The assembly of the light source and the light receivers may be housed within a flexible rubber cover to protect the same during use.
As will be seen from Figure 3, load determining devices are mounted one towards each end of each half-axle of the vehicle; preferably the devices are located as close to the respective suspension unit 11 of the vehicle as is practicable.
As mentioned previously, the individual glass or other light transmitting fibres of the light receiving array are connected to a converter operable to output an electrical pulse as and when each fibre is transmitting light. These pulses are in turn transmitted via a printed circuit board to a display unit 13 as illustrated in
Figure 5 of the drawings.
The display unit 13 would typically be situated in the cab of the vehicle and/or on the rear of the vehicle for ease of viewing when loading. The display unit 13 includes an ON-OFF switch and a series of lights for each sensing device. Thusr the left hand column of the unit is driven by the sensing device located at the left hand side of front axle of the vehicle; the second column from the left is driven by the sensing device located at the right hand side of the front axle; the third column from the left is driven by the sensing device located at the left hand side of the rear axle; and the right hand column is driven by the sensing device located at the right hand side of the rear axle. When a vehicle has three or more axles, further columns would be provided.
Each column comprises a vertical array of five lights, each being driven by one individual light receiver of the respective array. The lights of each column show, from top to bottom, when the vehicle is loaded to 25% of its fully laden weight; 50% of the fully laden weight; 75% of the fully laden weight; 100% of the fully laden weight; and at a predetermined percentage (e.g. 10% or 20%) above the fully laden weight (this latter percentage possibly being in accord with an excess permitted by the relevant authorities).
Thus, an operator can quickly see from the visual display, the extent of loading to each axle end of the vehicle.
One or more level sensors may be provided to show whether or not the vehicle bed or chassis lies generally in a horizontal plane. If not, then the various sensors may be adjusted to accommodate any variations which may occur due to the bed or chassis not lying generally horizontally.
In order to calibrate each load determing device, the vehicle with its bed or chassis generally lying in a horizontal plane, is loaded to its allowable fully laden weight (or to 108% of such weight) and the heights of the individual light receivers are adjusted so that the uppermost receiver is aligned with the light source. The vehicle is then gradually unloaded, each receiver being aligned so that it corresponds to a predetermined percentage of the vehicle's fully laden weight.Thus, in the example illustrated, the uppermost receiver corresponds to 108% of the maximum permitted laden weight; the second receiver corresponds to the vehicle's permitted laden weight; the third receiver corresponds to 75% of the vehicle's fully laden weight; the fourth receiver corresponds with 50% of the vehicle's fully laden weight; and and the lower most receiver corresponds to 25% of the vehicle's fully laden weight.
This calibration can be checked at periodical intervals to accommodate, for example, suspension unit wear. Calibration would preferably be carried out by a responsible authority and the devices rendered tamper proof in order to enable inspectors to rely upon the accuracy of the devices.
It will be understood that sensing devices other than the optical devices illustrated could be employed, one typical alternative being illustrated in Figure 4 of the drawings. In this arrangment, each sensing device comprises a series of electrical or electronic-switches 14 mounted on an arm 15 suspended from the undersurface of the vehicle chassis 16. The switches 14 are sequentially activated by mechanical fingers 17 upstanding from a carrier 18 mounted on the respective axle housing.
In the alternative embodiment of the invention illustrated in Figure 6, load determining devices as illustrated each comprising a tubular housing 21 are secured by brackets to the underside of the chassis or bed of the vehicle at positions above the axles or half axles of the vehicle. Mounted for sliding movement within each housina 21 is a slide 22 supported by a line 23 which is wound at one end onto an output shaft 24 of an electric motor 25. The other end of each line 23 is secured to a pulley 26 secured to the upper end of the slide 22. Thus, operation of each electric motor 25 effects either raising or lowering of the respective slide 22 within its tubular housing 21. If Figure 6 the slide is shown in its upper position in broken line and its lower position in full line.A switch 27 protrudes from the lower end of each slide 22, this switch operating to stop the electric motor as and when the switch comes into contact with the axle or half axle of the vehicle -or a plate or the like supported above this axle or half axle.
A vertical array of micro switches is positioned within the side wall of each housing 21, these being sequentially operated by a switching mechanism carried by the slide as it moves relative to the housing during loading of the vehicle.
In opertion of the load determining device illustrated in Figure 6, before loading of the vehicle begins each electric motor 25 is operated to cause the respective slide to move downwardly until the switch 26 makes contact with the respective axle or mounting plate.
Each slide is, therefore, supported by the respective axle or mounting plate. As loading progresses, so the vehicle bed moves down to cause the housings 21 to move over the slides 22 to activate sequentially the micro switches.
Once loaded satisfactorily, the slides are raised by operation of the electric motors 25 so that they are protected by their housings when not in use.
Advantages which accrue from weight determination devices in accordance with the invention include inter alia an ability to check whether a vehicle is overloaded; increased suspension unit life by reduced overloading; ability of an authority to check on loading without recourse to the use of weighbridges; enhanced vehicle safety; an ability to distribute a load evenly within a vehicle; and increased profitability due to a reduced or minimal likelihood of being faced with fines or loss of drivers through inadvertent overloading of a vehicle.
It will be understood that the foregoing is merely exemplary of devices in accordance with the invention and that modifications can readily be made thereto without departing from the true scope of the invention.
