Its model name literally means front-wheel-drive, one of the car's break-through innovations. Front-wheel drive ( FWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the front wheels only. Most modern front-wheel-drive vehicles feature a transverse engine, rather than the conventional longitudinal ...
Contents. 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.
Powertrain layout. The powertrain layout of a motorised vehicle such as a car is often defined by the location of the engine or motors and the drive wheels . Layouts can roughly be divided into three categories: front-wheel drive (FWD), rear-wheel drive (RWD) and four-wheel drive (4WD). Many different combinations of engine location and driven ...
Ackermann geometry. The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii . It was invented by the German carriage builder Georg Lankensperger in Munich in 1816 ...
Drivetrain. A drivetrain (also frequently spelled as drive train or sometimes drive-train) or transmission system, is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. [ 1]
Turning the handlebar rotates the front wheel with respect to the plane of the circumference of the rear wheel. Friction of the front wheel with the ground provides the lateral forces that steer the bicycle. Modern bicycles have the front-wheel ground-contact-point trailing behind the steering axis, which is the long axis of the bicycle fork ...
A locking differential is a mechanical component, commonly used in vehicles, designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack thereof) available to either wheel ...
The Geneva drive or Geneva mechanism is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel ( driven wheel) that advances it by one step at a time. The drive wheel also has an elevated circular ...
