Truck Transmission Loses Reverse, Owner Devises Way to Make It Go Backwards Anyway


(Video Link)

YouTube user hexdude24 owns a truck. The reverse gear in his transmission went out. He can't afford to fix it. In the meantime, he's using this device that he made. It slips under his rear wheels. As he drives forward, it pulls his truck backward.

Forgive me, readers: Alex hired me for my looks, not my brains. How does this system work? I'm struggling to understand it.

The rollers (the narrow white tubes) reverse the direction in which the rear wheels push on the ground. Imagine a pair of two gears meshed together or rubber wheels. If one gear turns clockwise, the other must turn counterclockwise. The truck's rear wheels are like the driving gear in this case, and the rollers act like the other gear. The tire turns "clockwise", and the roller "counterclockwise", just like putting the vehicle in reverse (the front wheels can spin freely in either direction). The chains serve as axles for the rollers, keeping them in place under the wheels. Makes sense?

Yes. What he said ^
The tires no longer touch the ground. Instead by going forward the tires drive the cylinders in reverse and the reversing cylinders are in contact with the ground.
