Definitions
- the mechanism for the hydrostatic regulation of the mechanism concerns the stepless speed regulation, which uses the principle of the gear pump.
- Execution consist of two intermeshing gears.
- the pair of wheels is mounted in a sealed housing and the spaces in which the supply channel and the discharge channel open out are formed in the contact points of the wheels. Due to the peripheral rotation, the liquid is foiled from the access space into the discharge space.
- This basic principle is modified in the various applications depending on the intended purpose and function, because this pump can also work as a drive unit.
- the device according to the invention for the hydrostatic regulation of the rotation of mechanisms, which consists of the gear transmission which is closed and sealed in the housing, where the separate rooms are formed, which are further equipped with the spin speed controller and the pressure medium supply is realized through the axle feed channel, the essence of which is that the gear transmission is formed by the planetary gear transmission, with space limited by the tip circle of the ring gear and the circular line part of the sun gear and the planet gear being filled by the segments which are the components of the regulating disc form, which is provided with the regulating valve.
- the overcurrent channels are formed in the segments, which switch through the constant pressure spaces created on the contact of the toothing of the individual wheels and which flow into the regulating valve to which the centrifugal regulator, which is mounted on the drive shaft, is kinetically connected.
- the regulating valve consists of two disks, which are displaceable and rotatably and rotatably rotatably on the drive shaft, the disk facing the regulating disk being provided with the needle closure elements which engage in the collecting channel in the regulating disk, on which one end of the spring is supported and the second end of the spring is supported on the disk of the regulating valve, its second disk being kinetically connected to the centrifugal regulator.
- Axle feed channel formed in the drive shaft is in the Place the distribution of the working pressure medium with a return valve and in it the distribution radial channels open, which are led out between the teeth of the sun gear.
- the device according to the invention creates a transmission gear which is able to transmit the rotary movement between the source of rotation and another mechanism and is capable of continuously changing the speed ratio and the torque ratio between the drive element and the driven element.
- This speed and torque ratio can be controlled either straight or through automatic regulation: or with another connected control mechanism.
- the increased performance is not due to the increased weight and the larger dimensions and is very compact.
- FIG. 1 shows a cross section through the device, where the internal arrangement of the wheels, the segments, the pressure chambers and of the switching channels is visible
- FIG. 2 shows a section in the plane AA from FIG. 1
- Gig. 3 represent a section in the plane B - 3 from FIG. 1.
- the device consists of a planetary gear
- the sun gear 1 is mounted on the drive shaft 10, which has an axis feed channel 1 6 drilled out in the axis.
- the axis feed channel 16 ends with a check valve 18, behind its closure element the radial distribution channels 17, which are designed between the teeth of the sun gear 1, open into the axis feed channel 16.
- the sun gear 1 is in permanent engagement with the planet gears 3, which are in permanent engagement with the ring gear 4, which is mounted on the driven shaft 5.
- This entire planetary gear 1, 3, 4 is tightly closed from the end faces by the regulating disks 9, which also form the carriers of the planet gears 3.
- the components of the regulating disks 9 form the segments 2, which fill the space between the ring gear 4 and the planet gears 3 so that the separate pressure spaces are formed when the individual gear wheels 1, 3, 4 come into contact.
- eight pressure chambers are always arranged opposite one another.
- the overflow channels 6 are arranged, which pass through the chamber with the same pressure and are merged into the collecting channel 14 of the regulating valve 7.
- the needle lock elements 1 3 engage in the collecting channel 14 and are fixedly connected to the disk 11, which is rotatably mounted on the drive shaft 10 with the second disk 1 2.
- the disks 11, 12 are rotatable relative to one another and are arranged so as to be displaceable in view of the drive shaft 10. Between the disc 11 and the regulating disc 9, a spring 15 is accommodated.
- the hard work pendulums of the centrifugal controller 8 are supported on the second disk 12.
- Rotation of the sun gear 1 The movement of the liquid, which is continuously supplemented by the axis feed channel 16, occurs by means of the overflow channels 6 on the principle of the function of the gear pump.
- the centrifugal pendulum of the centrifugal controller 8 is deflected by increasing the speed of the drive shaft 1 0.
- the centrifugal pendulums press the disc 11 via the second disc 12.
- the resistance of the spring 15 is overcome.
- the proposed device is possible as an automatic or semi-automatic transmission, a hydraulic clutch with the possibility of automatic regulation or for the construction of a hydraulic brake system, etc.

Abstract
Un dispositif servant à la régulation hydrostatique de la rotation de mécanismes est constitué d'un engrenage planétaire (1, 3, 4) qui comprend des chambres de compression traversées par des canaux de décharge (6). Ces canaux de décharge (6) s'ouvrent dans un canal collecteur (14) où le liquide en écoulement est étranglé par les éléments de fermeture à aiguille (13) commandés par le régulateur centrifuge (8). Ce dispositif peut être utilisé comme embrayage, comme frein ou comme transmission.
