Description

High-strength servo axle assembly with double tie rods

Technical Field

The utility model relates to the technical field of follow-up bridges, in particular to a high-strength follow-up bridge assembly with double tie rods.

Background

The air suspension for the follow-up axle is a vehicle component formed by parts such as a bearing air bag, a lifting air bag, a steering damper, a thrust rod, a tie rod and the like, and has the functions of improving the follow-up axle, increasing the bearing capacity of the whole vehicle, reducing tire wear and resistance of tires, along with compact structure, light dead weight and adaptability to the requirements of weighing and charging. The bridge is put down when the load is heavy, so that the number of the load-bearing bridges is increased; the rear axle is a rear driving axle component for vehicle power transmission. It is composed of two half-bridges, and can implement half-bridge differential motion. It is also a device for supporting the wheels and connecting the rear wheels. In the case of a front-axle driven vehicle, the rear axle is only a trailing axle and only plays a role of load bearing. If the front axle is not a drive axle, the rear axle is a drive axle, which in addition to the load-bearing function also serves as a drive and deceleration function as well as a differential function, and if the front axle is four-wheel drive, a transfer case is generally arranged in front of the rear axle. The rear axle is divided into a whole axle and a half-bridge, the whole axle is provided with a non-independent suspension, such as a plate spring suspension, and the half-bridge is provided with an independent suspension, such as a Macpherson suspension.
