AI Technical Summary
Existing technologies cannot guarantee low stiffness in the connection between the cab and the frame under normal operating conditions, and it is difficult to increase stiffness under stable handling conditions, resulting in poor vehicle handling and vibration isolation.
Design a hydraulic damping bushing for a driver's cab, comprising a main spring assembly and a secondary spring assembly. Through a liquid flow channel and hydraulic chamber structure, the main rubber spring dampens vibration under normal operating conditions, while the secondary rubber spring participates in vibration damping under stable handling conditions. The stiffness of the secondary spring assembly is adjusted by a drive unit to achieve adjustable stiffness.
The system improves vehicle stability and ride comfort under normal operating conditions, while enhancing rigidity under stable handling conditions to ensure vehicle operation stability and ride comfort.
