Automobile axle ( Also known as the axle) With the frame through suspension, Or a monocoque body) Install the wheels connected to both ends. Role: in the frame and the axle ( The wheels) Heritability and torque between suspension, rather than the axle. Axle's role is to bear the load of the car, keep the car on the road of moving. Axle can be integrated, such as: hydraulic trailer axle. As a huge barbell, both ends by suspension system to support the body, so integral axle usually cooperate with the independent suspension; Axle can also be broken open, like two umbrella in on both sides of the car body, and their respective through suspension system to support the body, so breaking axle with independent suspension. According to different driving mode, the axle is divided into drive axle, steering axle and steering bridge four axles and support. The steering axle and support bridge are driven bridge. Most of the cars driven by lead after ( FR) , so the front axle as steering axle and rear axle as the drive axle; And before the front drive ( FF) Automobile front axle be steering drive axle and rear axle bridge ACTS as a support. To bridge structure is basically the same, is composed of two steering knuckle and a beam. If the beam to the body, steering knuckle is the head, he swung his neck is that we often say that the king pin, wheel is installed on the steering knuckle, like the head with a straw hat. However, when you drive, turn straw hat, head did not turn, middle separated with bearing, head just sway. Neck - — King pin is wheel rotation axis, the axis axis is not perpendicular to the ground, the wheels themselves are not vertical, there is a lesson in wheel alignment. The difference between the steering drive axle and steering axle is everything is hollow, beam into a bridge shell, steering knuckle became a steering knuckle shell, because inside the root drive shaft. Because of this drive axle is located in the middle of the bridge shell differential in two, and turned into two half shaft. Two hat is not simply set on the head, with the inside of the two half shaft directly connected. Half shaft in the position of the 'neck' is more a joint - — Universal joint, so half shaft is turned into two parts, inside outside half shaft and half shaft. According to the structural type, suspension Bridges can be divided into broken open and integral type two kinds. Breaking axle for joint structure, it used with independent suspension; The centre of one-piece axle is rigid solid or hollow beam. It is more than independent suspension. According to the different movements of the wheels, can be divided into the drive axle, steering axle, steering axle drive axle and bearing bridge four types. Among them, steering axle and bearing bridge are driven bridge. General automobile front axle for more steering axle and rear axle or during and after more than two bridge for the drive axle; Cross-country car or most of the car's front axle is drive axle, steering axle is to drive axle is called; Some single bridge drive three axis motor ( 6×2) Tin ( Or rear axle) Is the drive axle, the rear axle ( Or tin) Are bearing bridge.
