A steering column may also perform the following secondary functions: energy dissipation management in the event of a frontal collision; provide mounting for: the multi-function switch, column lock, column wiring, column shroud(s), transmission gear selector, gauges or other instruments as well as the electro motor and gear units found in EPAS and SbW systems;
Marles steering gear was an hour-glass-and-roller steering gear for mechanically propelled vehicles invented by British inventor and businessman Henry Marles (1871-1955) who also gave his name to his joint-venture Ransome & Marles a major British ball-bearing manufacturer. Aside from ease of use Marles' steering's great appeal to drivers was ...
Rev-matching is where the driver uses the throttle to match the revs to the road speed so that gear changes are not jerky. This is commonly used by drivers with non-synchromesh gearboxes, or those driving racing vehicles [26] Double-clutching is required on non-synchro gearboxes. To double-clutch while downshifting: depress the clutch pedal and ...
Locking hubs. Locking hubs, also known as free wheeling hubs are fitted to some (mainly older) four-wheel drive vehicles, allowing the front wheels to rotate freely when disconnected (unlocked) from the front axle. This is done to reduce the mechanical resistance of the front-portion of the drivetrain when four-wheel drive is not in use. [1]
Available as options, anti-lock brakes and low-speed traction control became popular features. [15] For 1997, several updates were made to improve handling response and steering control [16] Showcased in the redesign was the new Modular V8 engine. First introduced in the 1991 Lincoln Town Car, the 4.6 L SOHC V8 replaced the overhead-valve 302 ...
Differential (mechanical device) A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering.

An automatic transmission (sometimes abbreviated AT) is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions.
By rotating the actuator's nut, the screw shaft moves in a line. Wheel and axle: Hoist, winch, rack and pinion, chain drive, belt drive, rigid chain and rigid belt actuators operate on the principle of the wheel and axle. A rotating wheel moves a cable, rack, chain or belt to produce linear motion. [1]
