Problems solved by technology
[0002] Suspension is an important part of the vehicle chassis, which has a great impact on the dynamic performance of the vehicle. The damping coefficient of the traditional shock absorber is a fixed value, which cannot meet the adjustment requirements of the damping coefficient of the shock absorber when the vehicle load changes, so it is difficult to achieve the required Satisfactory damping effect
The semi-active suspension developed in recent years can adjust the damping coefficient of the shock absorber in real time according to changes in vehicle driving conditions. However, due to its complex structure, slow response, high control system design requirements and reduced reliability, the overall performance is still to be further improved

The invention provides a pneumatic damp-adjustable coaxial integrated damping brace which comprises a damper, an air spring arranged above the damper, a pneumatic damp adjustable damping device fixed on a damper lateral wall and an air pipe connecting the air spring and the pneumatic adjustable damping device. The air spring and the damper are arranged coaxially and integrally. Damping coefficient of a damper can be adjusted according to vehicle load changes, larger damping coefficient is provided when a vehicle load is large, and smaller damping coefficient is provided when the vehicle load is small. The self-adaptation capacity of a suspension system is improved, and damping performance of a vehicle suspension is improved. The pneumatic adjustable damping device is simple in structure and fewer in parts and improves machining and assembling efficiency and reliability of the pneumatic damp-adjustable damping brace.
Description
technical field [0001] The invention relates to the technical field of vehicle chassis, in particular to an aerodynamically adjustable damping coaxial integrated vibration damping strut suitable for vehicles equipped with air suspension and whose effective load varies greatly. Background technique [0002] Suspension is an important part of the vehicle chassis, which has a great impact on the dynamic performance of the vehicle. The damping coefficient of the traditional shock absorber is a fixed value, which cannot meet the adjustment requirements of the damping coefficient of the shock absorber when the vehicle load changes, so it is difficult to achieve the required Satisfactory damping effect. The semi-active suspension developed in recent years can adjust the damping coefficient of the shock absorber in real time according to changes in vehicle driving conditions. However, due to its complex structure, slow response, high control system design requirements and reduced re...
