Description

Styreanordning for beltegående kjøretøy. Steering device for tracked vehicles.

Foreliggende oppfinnelse angår en styreanordning for beltegående kjøretøy hvor hovedkraftoverføringen til beltene skjer mekanisk over en vanlig differensial. The present invention relates to a steering device for tracked vehicles where the main power transmission to the tracks takes place mechanically via a conventional differential.

Det er ved kjøretøyer av denne art vanlig å anvende styrekoplinger og styrebremser som avvekslende arbeider på det ene eller annet belte, eller der anvendes en såkalt styrt differensial hvor man med styrebremser over et planetdrevsystem kan gi beltene forskjellig hastighet. In vehicles of this type, it is common to use steering couplings and steering brakes that work alternately on one or the other belt, or a so-called controlled differential is used where steering brakes over a planetary drive system can give the belts different speeds.

Hensikten med foreliggende oppfinnelse er å tilveiebringe en styreanordning av den innledningsvis nevnte art hvor man unngår bremser og deres slitasje og hvor der bare anvendes hydrostatiske kop-lingsorganer. The purpose of the present invention is to provide a control device of the type mentioned at the outset where brakes and their wear are avoided and where only hydrostatic coupling means are used.

Dette skjer ifølge oppfinnelsen ved at hver drivaksel fra differensialen er koplet med en felles hydraulisk motor hvor det hydrauliske kretsløp mellom motoren og den hydrauliske pumpe regulerer den innbyrdes omdreiningshastighet av drivakslene. According to the invention, this happens in that each drive shaft from the differential is connected to a common hydraulic motor where the hydraulic circuit between the motor and the hydraulic pump regulates the mutual speed of rotation of the drive shafts.

På denne måte kan man på en vanlig hjultraktor med uforandret drivverk anvende den hydrostatiske styreanordning ifølge oppfinnelsen både for hel- og halv-belter og gi traktoren terrenggående egen-skaper som en vanlig beltetraktor. Men oppfinnelsen kan også med fordel anvendes på spesiell beltetraktor. In this way, the hydrostatic control device according to the invention can be used on an ordinary wheeled tractor with an unchanged drive mechanism for both full and half tracks and give the tractor off-road characteristics like an ordinary tracked tractor. But the invention can also be advantageously applied to special crawler tractors.

To utførelseseksempler på oppfinnelsen skal forklares nærmere under henvis-ning til tegningen. Two embodiments of the invention will be explained in more detail with reference to the drawing.

av styreanordningen ifølge oppfinnelsen med en roterende hydraulisk motor og en hydraulisk pumpe. of the control device according to the invention with a rotating hydraulic motor and a hydraulic pump.

Fig. 2 viser skjematisk en annen ut-førelse av styreanordningen ifølge oppfinnelsen med en hydraulisk motor og en hydraulisk pumpe. Fig. 1 viser en styreanordning ifølge oppfinnelsen med en roterende hydraulisk motor 9 hvor drivhjulene 1 som driver beltene 2 drives av en differensial 10. Den ene drivaksel er over tannhjul koplet med motorens 9 rotor og den annen drivaksel er over tannhjul koplet med motorens 9 rotorhus. Det hydrauliske medium fra et reservoar 8 blir over en hydraulisk pumpe 7 og en styreventil 6 ledet inn og ut av motoren ved hjelp av en muffe på motorens aksel. Ved kjøring rett frem eller til-bake oppstår ingen relativ bevegelse mellom rotor og rotorhus i motoren. Skal kjøretøyet svinge pådras motoren over pumpen og styreventilen den ene eller annen vei slik at der oppstår forskjell i om-dreiningshastighetene av de to drivhjul og kjøretøyet svinger. På fig. 2 drives beltene 12 av drivhjul 11 som over tannhj ulsutveksling drives fra differensialen 10. Hver drivaksel for de to drivhjul 11 er over tannhj ulsutveksling forbundet med hvert sitt planetdrev idet planethj ulenes 13 opplagring i de to planetdrev er stivt forbundet med hverandre, solhjulene 14 er over et felles tannhjul 15 forbundet med en hydraulisk motor 16 som kan pådras den ene eller den annen vei ved hydraulisk medium fra et reservoar 8 over en pumpe 7 og en styreventil 6. Fig. 2 schematically shows another embodiment of the control device according to the invention with a hydraulic motor and a hydraulic pump. Fig. 1 shows a control device according to the invention with a rotating hydraulic motor 9 where the drive wheels 1 that drive the belts 2 are driven by a differential 10. One drive shaft is via gears connected to the rotor of the motor 9 and the other drive shaft is via gears connected to the rotor housing of the motor 9 . The hydraulic medium from a reservoir 8 is led via a hydraulic pump 7 and a control valve 6 into and out of the motor by means of a sleeve on the motor's shaft. When driving straight ahead or backwards, no relative movement occurs between the rotor and the rotor housing in the motor. If the vehicle is to turn, the engine over the pump and the control valve is applied one way or the other so that there is a difference in the rotational speeds of the two drive wheels and the vehicle turns. In fig. 2, the belts 12 are driven by drive wheels 11 which are driven from the differential 10 via a gear exchange. Each drive shaft for the two drive wheels 11 is connected via a gear exchange to each of its planetary gears, the bearing of the planetary gears 13 in the two planetary gears being rigidly connected to each other, the sun gears 14 are over a common gear wheel 15 connected to a hydraulic motor 16 which can be applied one way or the other by hydraulic medium from a reservoir 8 over a pump 7 and a control valve 6.
