Automobile handlingAutomobile handling and vehicle handling are descriptions of the way a wheeled vehicle responds and reacts to the inputs of a driver, as well as how it moves along a track or road. It is commonly judged by how a vehicle performs particularly during cornering, acceleration, and braking as well as on the vehicle's directional stability when moving in steady state condition. In the automotive industry, handling and braking are the major components of a vehicle's "active" safety, as well as its ability to perform in auto racing.
Automotive suspension design processAutomotive suspension design is an aspect of automotive engineering, concerned with designing the suspension for cars and trucks. Suspension design for other vehicles is similar, though the process may not be as well established.
Géométrie directionnelle d'AckermannLa géométrie de direction de Rodolphe Ackermann est un dispositif mécanique de direction d'une voiture ou d'un autre véhicule permettant, avec une géométrie simple, de braquer les roues droite et gauche d'un essieu, avec une légère différence d'angle. Ceci permet, lors d'un virage, que les roues internes et externes s'inscrivent dans des cercles de rayons différents (le cercle dans lequel s'inscrit la roue interne au virage étant d'un rayon inférieur au cercle dans lequel s'inscrit la roue externe au virage).
Weight distributionWeight distribution is the apportioning of weight within a vehicle, especially cars, airplanes, and trains. Typically, it is written in the form x/y, where x is the percentage of weight in the front, and y is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including handling, acceleration, traction, and component life. For this reason weight distribution varies with the vehicle's intended usage.
Suspension de véhiculeLes suspensions d'un véhicule sont les éléments permettant de relier les masses non suspendues (typiquement la roue, les pièces d'entraînement de roue, souvent les systèmes de freinage, etc) aux masses suspendues (typiquement le châssis, le moteur et tous les composants du véhicule fixés au châssis). L'utilisation de la suspension est imposée par les irrégularités de la surface sur laquelle se déplace le véhicule.
Directional stabilityDirectional stability is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium (water, air, road surface, etc.) when disturbed (rotated) away from that original direction. If a vehicle is directionally stable, a restoring moment is produced which is in a direction opposite to the rotational disturbance.
Véhicule (transport physique)vignette|Train de conteneurs. Un véhicule est mais cet article se focalise sur ce qui concerne le transport physique, quel que soit le milieu (terre, air, mer) et les moyens mis en œuvre pour y arriver (force animale ou mécanique par exemple). Il s'agit le plus souvent d'un moyen de transport motorisé, mais sa finalité première n'est pas toujours le transport en lui-même (engins de loisirs, travaux publics, machines agricoles, engins militaires).
