1, automobile front axle
The front axle, that is, the front axle, is a device that transmits various forces between the frame and the front wheel and the bending moment and torque they produce. The front axle is mostly driven axle, also called steering axle, which is generally distributed at the front end of the vehicle, so it is called front axle. It uses steering knuckles to connect the steering system. The steering force output by the steering gear can be transmitted to the wheels to realize the steering of the vehicle. It not only supports the sprung mass at the front of the vehicle, but also bears various longitudinal forces, lateral forces and related moments.
2. Automobile rear axle
The rear axle refers to the rear transmission shaft component for vehicle power transmission. It consists of two half-bridges, which can realize the differential motion of the half-bridges. It is also used to support the wheels and connect the rear wheels. If it is a front-axle driven vehicle, then the rear axle is just a follow-up axle, which only plays a bearing role. If the front axle is not a drive shaft, then the rear axle is a drive shaft. At this time, in addition to bearing, it also plays the role of driving, deceleration and differential speed. If it is a four-wheel drive, there is usually a transfer box in front of the rear axle. The rear axle is divided into a full axle and a half axle. The whole bridge is equipped with dependent suspension, such as leaf spring suspension, and the half bridge is equipped with independent suspension, such as McPherson suspension.
Extended data:
The front axle and the rear axle are part of the automobile chassis driving system. The driving system is the part where the car runs on the road. Connect the parts of the automobile assembly into a whole to support and ensure the running of the automobile.
Front axle and rear axle refer to the parts of front axle and rear axle. The front axle comprises a damping spring, a steering gear and a balance shaft, and the rear axle further comprises a transmission shaft and a transmission gear. The rear of multi-axle truck is also divided into driven rear axle and non-driven rear axle. The non-driven rear axle is not part of the driving wheel, and there is no transmission shaft connection. Generally, it is only applicable to heavy trucks and tractor heads with more than three axles.
Both the front axle and the rear axle are connected to the frame through elastic elements (such as coil springs, leaf springs, airbags, shock absorbers, etc.). ) to lift the car body and sedan chair. Usually, the front axle is the steering axle and the rear axle is the driving axle.
