Description

A COMPRESSED-AIR BRAKE SYSTEM TECHNICAL FIELD OF THE INVENTION AND BACKGROUNDART The present invention relates to a compressed-air brake systemfor heavy and medium heavy motor vehicles, comprising a frontbrake circuit and a rear brake circuit each having at least one reg-ular compressed-air tank configured to contain compressed-air of a regular pressure to be supplied to service brakes of the vehicle.
Such brake systems also have a third brake circuit in the form ofa parking brake circuit, and medium heavy motor vehicles does here mean motor vehicles with a weight 2 3.5 ton.
The compressed-air is produced by a compressor, which is nor-mally driven by the engine of the vehicle, and then supplied to saidregular compressed-air tanks of the front brake circuit and the rearbrake circuit. Braking of the vehicle is then obtained by actuationof valves supplying the service brakes of the vehicle with the com-pressed-air from said tanks. These service brakes may be of anyconceivable type controlled by supply of compressed-air, for ex-ample disc brakes or drum brakes. Said regular pressure of thecompressed air in said tanks is normally in the order of 10 bar.The total volume of said regular compressed-air tanks, which maybe more than one per brake circuit, is for a truck typically 90 litres+ 30 litres/further axle, which often means in the order of 200 li-tres. lt may constitute problems to fit this total volume for the tanksfor providing the total air volume needed for the brake system of such a truck. This means a number of air tanks arranged in the chassis of the truck, and they have sometimes to be mounted onthe outside of the frame reducing the available space for arrangingfuel tanks.
SUMMARY OF THE INVENTION The object of the present invention is to provide a compressed-airbrake system defined in the introduction being improved in at least some aspect with respect to such systems already known.
This object is obtained by providing such a compressed-air brakesystem with the features listed in the characterizing part of ap-pended patent claim 1.
By the arrangement of said at least one high compressed-air tankconfigured to contain compressed-air of a pressure exceeding theregular pressure by at least 50% and having this/these com-pressed-air tank(s) configured to contain a total amount of air in arelation of at least 1:1 to the total amount of air said regular com-pressed-air tanks are configured to contain, the same amount ofair as in brake systems having only regular compressed-air tanksmay be provided in a reduced total volume of compressed-airtanks. Accordingly, the brake performance of such a brake systemmay be maintained with a smaller total tank volume. Thus, spaceare made available for other equipment of the vehicle, such asadditional or larger fuel tanks.
US 4 496 192 discloses a compressed-air brake system havinghigh compressed-air tanks instead of regular compressed-air tanks and a pressure limiting member arranged between these compressed air tanks and valves controlling the supply of com-pressed air to the service brakes. This brake system is providedwith high compressed-air tanks for making the initiation of the braking action of the service brakes particularly rapid.
Furthermore, US 6 149 246 discloses a compressed air supplysystem for providing compressed air to a brake system as well asan air-suspension system of the vehicle so as to save volume needed for compressed-air tanks of these two systems.
According to an embodiment of the invention said relation is atleast 1.5:1 or at least 2:1. This means that the total volume forcompressed-air tanks may be reduced by 20%-60% or 25-65%,which means that a considerable space is made available for other purposes.
According to another embodiment of the invention said at least onehigh compressed-air tank is configured to contain compressed airof a pressure exceeding said regular pressure by 50%-600%, atleast 100% or at least 200%. The upper limit means that the vol-ume reduction for compressed air tanks will be at least 40% butalready the lower limit of 50% means a minimum volume reduction of nearly 20%.
According to another embodiment of the invention the total volumeof said high compressed-air tank(s) is at least the same as thetotal volume of said regular compressed-air tanks or exceeds this total volume by at least 50% or at least 100%. These features re- sult in a substantial possible reduction of the total volume of com-pressed-air tanks with respect to having the same amount of com- pressed air in only regular compressed-air tanks.
According to another embodiment of the invention the total volumeof said regular compressed-air tanks is s 15 litres, z 3 litres or 3-15 litres per axle of the vehicle. This results in a possibility to use small air tanks which will be easy to fit into the chassis of a vehicle.
According to another embodiment of the invention the total volumeof said high compressed-air tank(s) is 10-100 litres, 30-100 litresor 40-80 litres, which are suitable total volumes of tanks containingcompressed-air of a high pressure for obtaining a reduction of the total volume of compressed-air tanks aimed at.
According to another embodiment of the invention said regularcompressed-air tanks are configured to contain compressed-air ofa pressure of 7.5-15 bar, 10-13 bar or 12.5 bar. These are suitablelevels of compressed-air to be supplied to service brakes of a ve- hicle of this type.
According to another embodiment of the invention said com-pressed-air tank(s) is/are configured to contain compressed-air ofa pressure of 2 15 bar, 2 20 bar, 20-60 bar or 30-50 bar. Theselevels of the pressure in the high compressed-air tanks enables asubstantial reduction of the total volume of compressed-air tanksin a compressed-air brake system for heavy and medium heavy motor vehicles.
According to another embodiment of the invention said tanks ofthe system are configured to contain compressed-air in an amountof 1 bar x m3 - 3.5 bar x m3. These amounts of compressed air inthe tanks of the brake system makes it possible to obtain a brake performance required for this type of vehicles.
According to another embodiment of the invention the system com-prises a brake circuits protecting device from which said frontbrake circuit and rear brake circuit are branched, and the systemcomprises one said high compressed-air tank having the outletthereof connected to a said pressure limiting member in its turnconnected to said brake circuits protecting device or associatedtherewith so as to deliver compressed-air of a said regular pres-sure to the brake circuits downstream said device. This means thatone high compressed-air tank may be used to provide compressedair of a regular pressure to be supplied to the service brakes ofthe brake system to the regular compressed-air tanks of the indi- vidual brake circuits.
According to another embodiment constituting a further develop-ment of the embodiment last mentioned the system comprises afurther regular compressed air tank having the inlet connected tosaid pressure limiting member and the outlet connected to saidbrake circuits protecting device for delivering compressed-air of aregular pressure to this device. This constitutes another alterna-tive to have a high compressed-air tank upstream the branching ofthe brake circuits from the brake circuits protecting device butfeeding compressed-air with said regular pressure to the regularcompressed-air tanks of the brake circuits through the brake cir- cuits protecting device.
According to another embodiment of the invention the system hasa brake circuits protecting device from which said front brake cir-cuit and rear brake circuit are branched, and the front brake circuitand the rear brake circuit have each at least one said high com-pressed-air tank connected to said at least one regular com-pressed-air tank of that circuit through a said pressure limitingmember. This constitutes a further alternative to position highcompressed-air tanks to reduce the total volume of compressed-air tanks of a compressed-air brake system of the type to which the present invention is directed.
According to another embodiment of the invention the system alsocomprises a parking brake circuit having at least one said regularcompressed-air tank configured to contain compressed-air of a regular pressure to be supplied to the parking brake of the vehicle.
According to another embodiment of the invention one or more ofsaid brake circuits of the system has a plurality of said regularcompressed-air tanks connected in parallel to supply compressed- air to said brakes of the vehicle.
The invention also relates to a motor vehicle according to claim15.
Other advantageous features as well as advantages of the present invention appear from the description following below.
BRIEF DESCRIPTION OF THE DRAWINGS With reference to the appended drawings, below follows a specific description of embodiments of the invention cited as examples. ln the drawings: Fig1 is a schematic view illustrating how compressed-airtanks for a brake system may be arranged in a truck,and Figs 2-5 show parts of compressed-air brake systems of rele- vance for the present invention of four embodiments ofcompressed-air brake systems according to the inven- tion.
DETAILED DESCRIPTION OFINVENTION EMBODIMENTS OF THE Fig 1 shows schematically how compressed air tanks 1-4 of a com-pressed-air brake system may be arranged on the chassis 5 of amotor vehicle 6 in the form of a truck. lt appears that these com-pressed-air tanks may demand a considerable space restrictingthe space available for other components of the vehicle, such as fuel tanks.
Fig 2 shows schematically a compressed-air brake system for aheavy and a medium heavy motor vehicle according to a first em-bodiment of the invention. A compressor 7, which may be driven by the engine for the propulsion of the vehicle, is configured to create a flow of compressed-air through a conduit 8 to an air dryerunit 9 removing water created through the compression of air fromthe air flow and further to a high compressed-air tank 10 config-ured to contain compressed-air of a high pressure, for example inthe order of 20-40 bar. The outlet of the tank 10 is connected to aunit 11 containing a brake circuits protecting device 12 from whichthree brake circuits 13-15 are branched, namely a parking brakecircuit 13, a front brake circuit 14 and a rear brake circuit 15. Thus,this device 12 does for security reason restrict these three brakecircuits with respect to each other. The unit 11 also contains apressure limiting member 16 configured to limit the pressure ofcompressed-air arriving thereto from the tank 10 to a lower valueappropriate for compressed to be supplied to the parking brakeand service brakes of the vehicle. lt is shown how inlets of regularcompressed-air tanks 17, 18 in the rear and front brake circuitsare connected to the unit 11, and these regular compressed-airtanks are configured to contain compressed-air of a regular pres-sure, typically 12.5 bar, to be supplied to service brakes of thevehicle. lt is indicated that the outlets of these regular com-pressed-air tanks 17, 18 are connected to valves 19, 20 to be ac-tuated to supply compressed air to service brakes of the vehicle when braking the vehicle.
Thus, the high compressed-air tank 10 functions as a type of mas-ter compressed-air tank providing the regular compressed-airtanks 17, 18 with compressed-air. Thanks to the higher pressurein the high compressed-air tank 10 the total volume of the com-pressed-air tanks for containing a certain amount of compressed-air may be reduced with respect to having only regular com- pressed-air tanks in the brake system. The higher the pressure in the high compressed-air tank and the larger the volume of this air tank the more space may be saved.
Fig 3 shows a compressed-air brake system according to a secondembodiment of the invention differing from that shown in Fig 2 onlyby the arrangement of the pressure limiting member 16 directlydownstream the compressed-air tank 10 with a further regularcompressed-air tank 21 arranged between the pressure limitingmember 16 and the brake circuits protecting device 12. This is thereason for using the same reference numerals in this Figure as inFig 2. This constitutes a further alternative to provide the totalamount of compressed-air to be available for ensuring proper brak-ing of the vehicle through the compressed-air brake system.
Fig 4 shows a compressed-air brake system according to a thirdembodiment of the invention having a compressor 40, an air dryerunit 41, a brake circuits protecting device 42 from which a parkingbrake circuit 43, a front brake circuit 44 and a rear brake circuit 45are branched. The front brake circuit and the rear brake circuithave each a high compressed-air tank 46, 47 configured to containcompressed-air of a high pressure, and these are through a pres-sure limiting member 48, 49 connected to a regular compressed-air tank 50, 51 configured to supply compressed-air of a regularpressure, such as 12.5 bar, to service brakes of the vehicle byactuation of valves 52, 53. Thus, the high compressed-air tanks46,47 are configured to feed the regular compressed-air tanks 50,51 with compressed air for providing them with compressed-air ofa pressure suitable for controlling the service brakes of the vehi- cle.
Fig 5 shows a compressed-air brake system according to a fourthembodiment of the invention illustrating a possible variation of thestructure of the compressed-air brake system within the scope ofthe present invention, in which 59 is a compressor, 60 an air dryerunit, 61 a brake circuits protecting device, 62 a parking brake cir-cuit, 63 a front brake circuit, 64 a rear brake circuit, 65-68 highcompressed-air tanks configured to contain compressed-air of ahigh pressure, 69 and 70 pressure limiting members and 71-76regular compressed-air tanks configured to contain compressed-air of a regular pressure to be supplied to a parking brake and the service brakes of the vehicle.
The embodiments of the invention shown in the figures and de-scribed above are only a few of numerous possible embodimentsof the invention, and the embodiment selected for a particular mo-tor vehicle is depending upon a number of parameters, such as themain application of the motor vehicle, the number of axles thereofand the degree of priority to save space for making it available for other components than compressed-air tanks.
Thus, a lot of possible modifications of the embodiments disclosedabove would be apparent to a person with skill in the art withoutdeparting from the scope of the invention as defined in the ap-pended claims.
