Braked differential steering

It is for steering vehicles of continuous tracks. Input: white ring gear of n1 velocity. Output: blue shafts of large gears and wheels of n2 and n3 velocities. Pink satellite gears connect the two blue shafts. Each shaft has a grey brake controlled by an eccentric at the end of violet steering bar via green follower and yellow levers. The video shows: When the steering bar is at neutral position, two brakes do not work, the vehicle moves straight (n1 = n2 = n3). When the steering bar turns counter-clockwise, the left brake works, the left shaft stops (n2 = 0), the right shaft speeds up (n2 = 2.n1), the vehicle turns left with minimum radius. By slipping the brake (n2 is greater than 0; n1 = (n2 + n3)/2), turns of greater radius can be achieved. Here the differential with spur gears is used:    • Car differential with spur gears 1   It can be replaced with any kind of car differentials.
