This construction uses a differential. Both wheels could turn with different speed and this makes a construction much more stable when turning. 

You can attach a frame around the front wheels to make them more stable and to allow for better aligning. The module extends the front wheel built at BigDaddy Front - front wheels mechanism module for a large LEGO Mindstorms Competition Robot
