Leopard 2. Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both.
A later design of cross-drive transmission, the Allison X1100, was used in the 1970s experimental US MBT-70 and XM1 [3] tanks, then later adopted in the M1 Abrams.This adopts a different principle for the steering cross-coupling: instead of a hydro-dynamic torque converter, it uses a hydrostatic combination of a hydraulic pump and a hydraulic motor.
An electric motor drives a shaft on which is arranged a series of cams or a drum studded with pegs along its surface. Associated with each cam is one or more switches.The motor rotates at a fixed speed, and the camshaft is driven through a speed reducing gearbox at a convenient slow speed.
The dashpot timer is a fluid time-on-timer that can be used in definite time motor acceleration starters and controllers. A dashpot timer is a container, a piston, and a shaft. The dashpot timer functions when a magnetic field forces a piston to move within a cylinder when the coil is energized.
The key feature of the Ward Leonard control system is the ability to smoothly vary the speed of a DC motor, including reversing it, by controlling the field and hence the output voltage of a DC generator, as well as the field of the motor itself. As the speed of a DC motor is dictated by the supplied voltage, this gives simple speed control.

The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classification of locomotive axle arrangements (based on counting either the axles or the bogies).
