Abstract

A differential is required, for example, in a motor vehicle in order to compensate for the different path lengths of the two driving wheels of a live axle during cornering. However, the previous differential has the disadvantage that it distributes the torque uniformly to the driving wheels. If one driving wheel has low adhesion here, the vehicle may remain stationary. This is due to the fact that the other driving wheel receives only the same torque and this torque is not sufficient to drive the car. This cannot occur with the controlled differential. This differential prevents a situation where the driving wheels receive too little torque. This puts the motor vehicle in a considerably better position on the road. The controlled planetary differential comprises two planetary gear sets and a control wheel. The two planetary gear sets must be driven in opposite directions. Either the ring gears or the sun gears are driven. The two planet carriers must be rigidly connected to one another. The control wheel must furthermore be rigidly connected to the planet carriers. Control is exercised by rotating or fixing the control wheel.

Description

Beschreibung:Description:

Geregeltes Planetendifferentialgetriebe Eile Erfindung betr fft ein Differentialgetriebe, welches aus zwei Planetengetrieben aufgebaut ist und durch ein speziell angedeordnetes Steuerrad geregelt wird. Mit diesem Differentialgetriebe kann zum Beispiel, bei einem Kraftfahrzeug das Drehmoment der Kardanwelle kontinuierlich auf die beiden Antriebsraeder einer Achse verteilt werden. Ein Differentialgetriebe ist notwendig in einem Kraftfahrezeug, da bei einer Kurvenfahrt unterschiedlich Weglaengen der beiden Antriebsraeder auftreten. Ein herkoemmliches Differentialgetriebe hat den Nachtei, dass es den Drehmoment gleichmaessig auf die Antriebsraeder verteilt. Da aber den beiden Antriebsraedern nie die gleiche Reibung entsgegengesetzt wird, ist dies Nachteilhaft.Variable speed planetary differential gear Rush invention concerns a Differential gear, which is made up of two planetary gears and through a specially arranged steering wheel is regulated. With this differential gear For example, in a motor vehicle, the torque of the cardan shaft can be continuous be distributed over the two drive wheels of an axle. A differential gear is necessary in a motor vehicle because it is different when cornering Path lengths of the two drive wheels occur. A conventional differential gear has the disadvantage that it distributes the torque evenly to the drive wheels. But since the two drive wheels are never opposed to the same friction, this is disadvantageous.

Ganz besonders auf einem Untergrund welcher den Antriebsraedern eine schlechte Haftung bietet, (zum Beispiels: Schlamm, Els, Schnee, Unebenheiten). Bei diesen Extremfaellen kann es vorkommen, dass sich ein Antriebs dreht, das Zweite aber stillsteht und das Fahrzeug ebenfalls stllsteht, weil die Bodenhaftung des drehenden Antriebsrades zu gering ist. Die Bodenhaftung der Antriebsraeder kann vergoessert werden, durch Differentialsperre, Allrad oder zum Beispiel durch Kettenmontage Diese Loesungen weisen aber alle groessere Nachteile auf.Especially on a surface that is one of the drive wheels offers poor adhesion (for example: mud, els, snow, bumps). at In these extreme cases it can happen that one drive turns, the second but stands still and the vehicle also stands still because the grip of the rotating drive wheel is too low. The traction of the drive wheels can can be enlarged, through differential lock, four-wheel drive or, for example, through chain mounting However, these solutions all have major disadvantages.

Am geeignesten waere hier ein geregeltes Differentialgetriebe und dieses moechte ich hier vorstellen und unter Patentschutz stellen lassen Da sich das herkoemmliche Differentialgetriebe nicht regeln laesst, musste ich ein neues entwickeln. Es haneldt sich hierbei um mein Planetendifferentialgetriebe.A regulated differential gear would be most suitable here I would like to introduce this here and put it under patent protection the conventional differential gear couldn't be regulated, I had to get a new one to develop. This is my planetary differential gear.

Das Planetendifferentialgetriebe besteht aus zwei Planetengetrieben. Die beiden Planetenradtraeger der Planetengetriebe muessen fest miteinander verbunden sein. Mit den Planentenradtraegern muss ein Steuerrad fest verbunden sein, womit dann das Getriebe geregelt wird. Die Planetenradtrager selbst koennen auch als Steuerrad fungieren. Die beiden Planetengetriebe muessen entgegengesetzt angetrieben werden. Es koennen die Hohlraeder oder die Sonnenraeder angetrieben werden. Durch speziellen Antrieb des Steuerrades koennen nun die Planetenradtraeger in Bewegung gesetzt werden. oder festgehalten werden Dadurch kann das Drehzahlverhaeltnis der be 1 den Abtriebsraeder (Planetengetriebe) veraendert werden.The planetary differential gear consists of two planetary gears. The two planetary gear carriers of the planetary gears must be firmly connected to each other be. A steering wheel must be firmly connected to the tarpaulin wheel carriers, with which then the transmission is regulated. The planet carrier itself can also be used as a steering wheel act. The two planetary gears must be driven in opposite directions. The hollow wheels or the sun wheels can be driven. By special Drive of the steering wheel can now be set in motion the planetary gear carriers. or be held (Planetary gear).

Man kann mit diesem diesem Planetendifferentialgetriebe ein Drehmoment kontinuierlich in zwei Drehmomente aufteilen.You can get a torque with this planetary differential gear continuously split into two torques.
