Abstract

1. Sensor for anti-skid and anti-slip systems for measurement of vehicle shaft speed having a wheel having magnetic poles fixed on a wheel axis (3) and a pulse transmitter (8), characterised in that a bevelled wheel (4) is provided as the poled wheel, of which the pole faces (10) form at least approximately part of a spherical surface, the centre of which is coincident with the centre (11) of the spherical bearing which carries the wheel axis.

Description

Foreliggende oppfinnelse vedrører en målglver for glide- og slippbeskyttelsesanlegg til måling av omdreiningstallet for kjøretøyaksler med et til en hjulaksel anordnet kjegletannhjul som polhjul og en pulsgiver. The present invention relates to a gauge for skid and slip protection systems for measuring the number of revolutions of vehicle axles with a bevel gear arranged on a wheel axle as a pole wheel and a pulse generator.

Det er kjent I praksis en målgiver ifølge ingressen til patentkravet, for skinnegående kjøretøyer ved hvilke det er festet et polhjul utformet som et sylindertannhjul ved frontsiden av en hjulaksel. En magnetisk pulsgiver er anordnet i aksellagerlokket, således at mellom dens måleflate og toppsirkelen av sylindertannhjulet oppstår en klaring på fra 0,5 til 1,2 mm. Hjulaksellageret er i dette tilfellet utformet som et rulleaksellager. In practice, a gauge is known according to the preamble to the patent claim, for rail-running vehicles to which a pole wheel designed as a cylindrical toothed wheel is attached to the front side of a wheel axle. A magnetic pulse transmitter is arranged in the axle bearing cap, so that between its measuring surface and the top circle of the cylinder gear there is a clearance of from 0.5 to 1.2 mm. In this case, the wheel axle bearing is designed as a roller axle bearing.

US-patent 3801845 og 4171495 viser begge kjegletannhjul som virker på samme måte som det ovenfor nevnte sylindertannhjul. US patents 3801845 and 4171495 both show bevel gears which work in the same way as the above-mentioned spur gear.

Slike målgivere kan ikke anvendes for kjøretøyer utrustet med pendellager, da pendelbevegelsen til polhjulene ;kan være Such gauges cannot be used for vehicles equipped with pendulum bearings, as the pendulum movement of the pole wheels can be

i in

større enn avstanden mellom pulsgiveren og polhjulet, særlig ved pendelvinkler fra og til f.eks. ± 3°. greater than the distance between the pulse generator and the pole wheel, especially with pendulum angles from and to e.g. ± 3°.

Oppfinnelsen som den er karakterisert i kravet, løser oppgaven av å skaffe en målgiver for bruk på pendellagre, ved hvilke de tillatte pendelbevegelser er negligerbare. The invention as characterized in the claim solves the task of providing a target sensor for use on pendulum bearings, in which the permitted pendulum movements are negligible.

Fordelene som oppnås gjennom oppfinnelsen kan ses i det vesentlige deri at beskadigelse henholdsvis ødeleggelse av pulsgiveren er gjort unngåelig. The advantages achieved through the invention can be seen essentially in that damage or destruction of the pulse transmitter is made avoidable.

I det følgende blir oppfinnelsen nærmere forklart ved hjelp av kun en utførelsesmåte representert ved tegningen. In the following, the invention is explained in more detail using only one embodiment represented by the drawing.

Den enkeltstående figur viser et snitt gjennom en del av et pendelrullelager i et skinnegående kjøretøy. Et aksellagerhus 1 rommer et pendelrullelager 2 med sentrum 11, med hvilke den ene del av en hjulaksel på sin side er dreibart opplagret. På frontsiden av hjulakselen 3 er det festet gjennom skruer 5 et kjeglehjul 4 med tenner 14 utformet som polhjul. I et aksellagerlokk 7 festet med. skruer 6 til aksellagerhuset 1 er det festet en magnetisk pulsgiver 8, således at en luftspalte A på eksempelvis 0,5 til 1,2 mm adskiller en måleflate 9 til pulsgiveren 8 fra toppsirkelflaten til kjeglehjulet 4 som i det videre benevnes som poloverflaten 10. Poloverflaten 10 blir tilnærmet omhyllet av en kulesoneoverflate, hvorved kulesenteret sammenfaller med senteret 11 til pendelrulle-lageret 2. Likeens er aksen 12 til pulsgiveren 8 rettet mot dette sentrum 11. En elektrisk kabel 13 forbinder pulsgiveren 8 med en her ikke nærmere angitt, i og for seg kjent glide-og rotasjonsbeskyttelsesanordning. The single figure shows a section through part of a pendulum roller bearing in a rail-running vehicle. An axle bearing housing 1 houses a pendulum roller bearing 2 with a center 11, with which one part of a wheel axle is rotatably supported on its side. On the front side of the wheel axle 3, a bevel wheel 4 with teeth 14 designed as pole wheels is attached through screws 5. In an axle bearing cap 7 attached with. screws 6 to the axle bearing housing 1, a magnetic pulse transmitter 8 is attached, so that an air gap A of, for example, 0.5 to 1.2 mm separates a measuring surface 9 of the pulse transmitter 8 from the top circular surface of the bevel gear 4, which is referred to in the following as the pole surface 10. The pole surface 10 is approximately enveloped by a ball zone surface, whereby the ball center coincides with the center 11 of the pendulum roller bearing 2. Similarly, the axis 12 of the pulse generator 8 is directed towards this center 11. An electric cable 13 connects the pulse generator 8 with one not specified here, in and for known sliding and rotation protection device.

Med fordel kan innvirkningen av pendelbevegelsen helt elimineres, når tanntoppen av tannen 14 utformes ringformet til senteret 11. Videre kan kjeglehjulet istedet oppvise tenner av en annen polart, f.eks. ved hjelp av trykte kretser, hullskiver etc, hvorved i det minste tilnærmet kulesoneformede poloverflater opprettholdes. Advantageously, the influence of the pendulum movement can be completely eliminated, when the tooth apex of the tooth 14 is shaped annularly to the center 11. Furthermore, the bevel wheel can instead have teeth of a different polarity, e.g. by means of printed circuits, perforated disks etc., whereby at least approximately spherical zone-shaped pole surfaces are maintained.
