Description

15 20 25 30 35 504 510 2 omradet mellan stödytorna tillàts att elastiskt deformeras under trycktankens fastspänning fas en kraftbalans och en kraftverkan, som ej tappar spännkraft och gör trycktankens fastspänning mycket tillförlitlig och väsentligen okänslig för vibrationer, yttre krafter och störande moment. Med vulster pà bada sidor om stödorganets mellanliggande de- formerbara omràde förenklas monteringen av spännbandet ytterligare genom att spännbandet kan styras till ett cent- rerat och riktigt läge pà stödorganet för god balans och kraftverkan mellan stödorgan och tank. _11.. The area between the support surfaces is allowed to elastically deform during the clamping of the pressure tank, a force balance and a force action which does not lose clamping force and makes the clamping of the pressure tank very reliable and substantially insensitive to vibrations, external forces and disturbing moments. With beads on both sides of the intermediate deformable area of the support member, the assembly of the strap is further simplified by the strap being guided to a centered and correct position on the support member for good balance and force action between support member and tank. _11 ..

Figur 4 visar bakifran tankinfästningen i fig 2.Figure 4 shows from behind the tank attachment in figure 2.

Figur 5 visar tankinfästningen med spännband enligt fig 2. 1.. J I figurerna visas en trycktank l fastspänd med ett spännband 2 pà ett chassifast stödorgan sásom en hallare 3 för tanken med tvà fran varandra eventuellt genom anordnade vulster 4, 5 axiellt àtskilda upphöjningar, vilkas ytor verkar som stödytor 6, 7 för tanken vid dess fastspänning med det omlagda spännbandet. Ett mellan upphöjningarna befintligt omrade 8 verkar som mothàll för det omlagt monterade spänn- bandet och är med en spalt mot tanken anordnat att tillàtas att elastiskt deformeras vid spännbandets àtdragning och böjas mot tanken utan att kontakt med tanken behöver er- hàllas. Vulsterna 4, 5 pà hallaren 3 är riktade utàt fran tanken och i första hand tänkta att underlätta monteringen av spännbandet och styra in och centrera spännbandet pà rätt plats pà hállaren. Hàllaren kan vara fastsatt pà ett underlag 10 15 504 510 3 sásom en rambalk 9 med fyra skruvförband 10.Figure 5 shows the tank attachment with tensioning straps according to Figure 2. 1. The figures show a pressure tank 1 fastened with a tensioning strap 2 on a chassis-fixed support member such as a holder 3 for the tank with two spacers possibly arranged by beads 4, 5 axially separated elevations, surfaces act as support surfaces 6, 7 for the tank at its clamping with the rearranged clamping band. An area 8 present between the elevations acts as an abutment for the re-assembled strap and is arranged with a gap against the tank to be allowed to elastically deform when the strap is tightened and bent towards the tank without having to maintain contact with the tank. The beads 4, 5 on the holder 3 are directed outwards from the tank and are primarily intended to facilitate the assembly of the strap and guide in and center the strap in the right place on the holder. The holder can be attached to a base 10 such as a frame beam 9 with four screw connections 10.

Med denna typ av fastsättning räcker det med ett enda spännband som anordnas mellan stödorganets upphöjningar med eller utan vulster. Stödorganet eller hällaren kan med fördel vara utformad med relativt liten tjocklek eller vara anordnad att vid spännbandets àtdragning för tankens fast- spänning deformeras mer eller mindre. Vid behov kan fastspän- ningen tillåtas deformera stödorganet så att detta även kom- mer i kontakt med tanken vid spännbandet mellan upphöjning- arna eller vulsterna. Pa detta sätt kan erhàllas en kontroll pà att spännbandet har fastspänts med tillräcklig spännkraft.With this type of fastening, a single strap arranged between the supports of the support member with or without beads is sufficient. The support member or pourer can advantageously be designed with a relatively small thickness or be arranged to deform more or less when the tensioning strap is tightened for the tank. If necessary, the clamping can be allowed to deform the support member so that it also comes into contact with the tank at the clamping band between the elevations or beads. In this way, a check can be obtained that the clamping band has been clamped with sufficient clamping force.

Med denna typ av fastspänning fär stödorganet i första hand tillatas att deformeras för att fä en ytterligare spännkraft.With this type of clamping, the support member is primarily allowed to deform to obtain an additional clamping force.

Vid andra tillämpningar kan också tanken och/eller spänn- bandet tillåtas att ytterligare deformeras för att fa en förstärkt spännkraft.In other applications, the tank and / or the tensioning belt can also be allowed to be further deformed in order to obtain a reinforced tensioning force.

Claims

10 15 20 25 30 35 504 510 BAIENIKRAY

1. A method of arranging an attachment of a pressure tank in a vehicle, characterized in that the tank (1) is fixed between two support surfaces (6,7) on the vehicle and a tensioning strap (2), that the tensioning strap (2) is tightened fixed around the tank (1) and an area between the support surfaces (6,7) at a distance from the tank (1) and that this area was allowed to elastically deform at the clamping of the tank (1) to give an additional clamping force to the attachment.

Pressure tank attachment for a pressure tank such as a pressure tank for compressed air to a braking system in a vehicle, characterized in that a support member (3) on the vehicle for the tank (1) between the tank (1) and a base is formed with two separate support surfaces (6, 7) and an intermediate area (8) arranged to be separated by a gap from the tank during its attachment and that the intermediate area (8) is arranged to be elastically deformable so that when using a folded strap ( 2) and its tension for fixing and holding the tank against the support member is elastically deformed to give an additional clamping force to the attachment.

Pressure tank attachment according to claim 2, characterized in that the support member is provided with beads (4, 5) between each support surface (6, 7) and the intermediate area (8) directed outwards from the tank during its attachment to mounting of the strap (2) control the position of the strap (2) and thereby facilitate its mounting.

Pressure tank attachment, according to claim 2 or 3, characterized in that the support member is designed as a holder (3) and arranged to be attached to a base such as a beam (9), for example a frame beam with screw joints (10).
