A13/ Covenanter information request


Recommended Posts

Chris,

 

it was a conventional four speed gearbox. The steering was achieved with Wilson steering units, one bolted on each side of the gearbox. These used pneumatically controlled brake bands to apply epicyclics that varied the speed of the tracks. There was also a further external band brake between the steeing unit and the final drive to give a skid turn and act as a main brake.

 

The Merritt Brown combined speed change and steering in one unit and was first used in Churchill.
