differential gear

This design would have been simpler than using a differential gear.

Other locking systems may not even use differential gears but instead drive one wheel or both depending on torque value and direction.

When the trailer's wheels turn, the differential gears spin and power the blades.

It is like the differential gear on the back axle of a car.

In a car, differential gears compensate for such unequal travel.

There were several disadvantages that accompanied the lack of a true differential gear.

This centered the weight more proportionately and kept the differential gears protected.

The addition is done by an analogue method, using a differential gear.

It was tried to avoid the use of sprockets, chains and a differential gear as each wheel worked completely independent from the other.

There were thirty gears, all enmeshed, even a differential gear.
