Assemble it and discover the principle of working of the Car Differential.

Learn How the Differential Works
The Ugears STEM Lab Differential is a stylised educational model designed to demonstrate the core principles behind how a car differential operates. This clever mechanism allows wheels on the same axle to rotate at different speeds, enabling smooth turning without skidding, reducing tyre wear, and improving overall vehicle control. Once assembled, you can interact with the model by adjusting the control lever to explore different modes, including independent wheel movement and locked rotation.

Experiment and Discover
Go beyond the build with the included Pocket Model Study Guide. This resource explores the creation story, mechanism design, and key concepts behind the differential, along with engaging tasks to deepen your understanding. It’s a hands-on way to connect theory with real-world application.

Augmented Reality Experience
Bring your learning to life with integrated Augmented Reality features. Using the Ugears app, you can explore how similar mechanisms are used in real production environments and interact with digital overlays that enhance your understanding of the model.

When and Who Invented It
The differential was invented in 1825 by French engineer Onesiphore Pecqueur. It was later refined in the 1930s by German automotive engineer Ferdinand Porsche, helping shape the modern automotive systems we rely on today.

Where It’s Used
Differentials are a key component in vehicle transmission systems, improving manoeuvrability and performance by allowing wheels to adapt to varying speeds during turns.

Everything You Need in the Box
Like all Ugears STEM Lab models, this kit includes everything required for a complete build and learning experience. Pre-cut wooden components are easy to assemble without glue or tools, simply push the pieces out and slot them together. A detailed, step-by-step colour instruction manual ensures a smooth building process.

You’ll also gain access to a digital Study Guide via QR code, packed with explanations, definitions, and insights into how the mechanism works, along with examples for further hands-on exploration.
