Das Differential - Fast jeder hat schon mal davon gehört - das gibts wohl irgendwo im Auto - aber wer kann wirklich sagen wie es funktioniert? Die wenigsten vermutlich. Das werden wir mit diesem Set ändern. Die Funktion und Bauart dargestellt in einem schicken kleinen Modell - ideal auch für Schulen als Anschauungsobjekt.

Ursprünglich entwickelt wurde das Fahrzeug-Differential 1825 vom französischen Ingenieur Onesiphore Pecqueur - und dann ca. 100 Jahre später wurde es von Ferdinand Porsche himself deutlich nachgebessert. Erste Differantiale wurden aber auch schon in der Antike nachgewiesen. Und natürlich hatte daVinci so etwas auch im Programm ;-)

Es dient im Fahrzeug dazu, unterschiedliche Geschwindigkeiten auf der gleichen Achse zuzulassen. Fährt ein Fahrzeug eine Kurve, dreht sich das innere Rad langsamer als das äussere Rad - das Differential macht zum einen die Lenkung leichter und verhindert hohen Verschleiß an den Reifen.

Wie bei allen unseren Modellen gilt: Kein Klebstoff erforderlich. Die Teile sind mit einem Laser vorgeschnitten und müssen nur noch aus der Platte herausgebrochen und zusammengesteckt werden.

Maße: 175x135x105mm

Teile: 163

Geeignet ab 14 Jahren

Great for the price
The item is great bit I wish it were a bit more sturdy and it folded flat. It folds into a square so it does take up some room when it's not in use.

Cheap, screw holes don't line up, screen is to short, and bars take WD-40 and a mallet
This has been my worst purchase on Amazon ever. DO NOT BUY. My first issue was that bars #4 and #5 would not go together, I ended up buying WD-40 and a mallet and that kind of got them together. Now I went to but the screen on (which is almost see thought) and the screen is to short. I can't attached the bottom bar to the tall bar. The screw hole is in the wrong spot, so the screen is not secure. No amount of pulling on the screen will make it grown .25" longer. Since I can't get the bars secure the walls are not steady and fall over easily. The feet did go together very nice. I can't return them according to Amazons policy. I bought 2 sets. I'm not going to try to build the other set I have. And I can't take apart the first set, since the bars are so tightly together. Also the polls have rust on them.

Very Poor Built Quality
Color: Black, Size: 3-Panel
They use cheap tarp like cloth that you might find on a tent, so it is not suitable as a teleconferencing background without blur applied. The legs are flimsy and lack rubber feet, so it will scratch floors. The tubing is flimsy and very hard to move and adjust. This is only good if you are setting it up somewhere like a gym or a garage.

These are PERFECT for my Art Show coming up!
This is going to be PERFECT for my Art Show display. And also....EASY to put up and take down as well as store. I'm so grateful to have found them! They are super light weight. And sturdy for my application. And elegant and have clean lines for my display. I have ivy draped and also fairy lights which make it look classy yet simple! Love them!
