AI Technical Summary

Technical Problem

In the existing technology, the front suspension system of the cab is prone to lateral movement and abnormal noise during driving. In addition, the gap between the inner cylinder of the rubber sleeve of the suspension system base and the outer cylinder of the lateral sleeve is large, making it difficult to solve the abnormal noise problem and affecting the driving experience.

Method used

A cab front suspension support mechanism was designed, which adopts an upper bracket with sleeve welding assembly. By setting ferrules and rubber sleeves at both ends of the assembly for transition rotation connection, the excess clearance generated by rotational fit is eliminated. The swing of the small swing arm welding assembly is restricted by fixing bolts and top rod bolts, thereby reducing vibration and abnormal noise.

Benefits of technology

It effectively eliminates abnormal noises caused by gaps in the suspension system, improves driving comfort, has a simple structure, is easy to install and use, and is suitable for widespread promotion.
