Description

Technical Field

[0001] The utility model relates to the technical field of steering axles, in particular to an automobile air suspension follow-up steering axle. Background Art

[0002] A steering axle refers to an axle that is responsible for steering. The front axle of a general car is a steering axle, and the front and rear axles of a four-wheel steering car are both steering axles. It uses the steering knuckle in the axle to deflect the wheels at both ends at a certain angle to achieve the steering of the car. In addition to bearing the vertical load of the car, it also bears the longitudinal force and lateral force and the torque caused by these forces. The steering axle is usually located at the front of the car, so it is often called the front axle. The steering axle structure of various models is basically the same, mainly consisting of a front beam and a steering knuckle. For front-wheel drive cars and all-wheel drive cars, the front axle has to steer and transmit power, so it is called a steering drive axle. For common rear-wheel drive cars, the front axle does not transmit power, but has to undertake the steering task. It is both a steering axle and a driven axle. This kind of steering axle, if using non-independent suspension, is an integral bridge; if using independent suspension, it is a disconnected bridge.

[0003] In the normal operation of the existing steering axle, the kingpin seat does not have a load-bearing structure, is subjected to large forces during use, and is prone to deformation or breakage. In addition, during the steering process of the steering wheel, it is impossible to stably align the steering wheels at both ends at the same angle after rotation, and there is a certain error. An automobile air suspension follow-up steering axle is needed to solve this problem. Utility Model Content
