Which part of the car is the bridge head?

[MelanieLee]

The bridge head of a car refers to the steering axle. Here is an introduction about the axle: 1. Introduction: The car axle (also called the axle shaft) is connected to the frame (or the load-bearing body) through the suspension, with wheels installed at both ends. The function of the axle is to bear the load of the car and maintain normal driving on the road. 2. Types: The axle can be an integral type, like a huge barbell, with both ends supporting the body through the suspension system, so the integral axle is usually matched with a non-independent suspension; the axle can also be a split type, like two umbrellas inserted on both sides of the body, each supporting the body through the suspension system, so the split axle is matched with an independent suspension. 3. Maintenance: Before driving, check whether the external connecting bolts of the axle are loose, whether the axle is leaking oil, and whether the wheel hub and reducer assembly are making abnormal noises.
