What is the front axle structure of a car?
1 Answers
The front axle structure of a car consists of: front axle, kingpin, steering knuckle, brake assembly, wheel hub assembly, steering arm, and tie rod assembly. The front axle is a device that transmits various directional forces between the frame and the front wheels, as well as the resulting bending moments and torques. It is connected to the steering system via the steering knuckle, allowing the steering force output by the steering gear to be transmitted to the wheels to achieve vehicle steering. The front axle of a car not only supports the sprung mass of the front part of the vehicle and bears vertical loads but also withstands various longitudinal forces, lateral forces, and related moments. The front axle of a car can be categorized by brake type into drum brakes and disc brakes, and by brake system into air brakes and hydraulic brakes (single-leading-shoe and duo-servo types). The axle load ranges from 0.5 to 7.5 tons for micro trucks, light trucks, medium trucks, and heavy trucks.
