Two-stage shock absorption automobile suspension structure and locking control method

Abstract

The invention relates to the technical field of automobile suspensions, in particular to a two-stage shock absorption automobile suspension structure. The two-stage shock absorption automobile suspension structure comprises a shock absorption body and a locking control mechanism. The shock absorption body is composed of a first-stage shock absorption structure and a second-stage shock absorption structure which are connected in series. The first-stage shock absorption structure comprises a first-stage damper, a first-stage inerter and a first-stage spring. The first-stage damper is connected with the first-stage inerter in series. The first-stage damper and the first-stage inerter which are connected in series are connected with the first-stage spring in parallel. The second-stage shock absorption structure comprises a second-stage damper, a second-stage inerter and a second-stage spring. The second-stage damper, the second-stage inerter and the second-stage spring are connected in parallel to form a second-stage spring, damper and inerter parallel connection integrated device. The locking control mechanism comprises an inerter braking locking piece which can be driven to lock thefirst-stage inerter, the rigidity of a suspension system is increased, and traveling safety and control stability are improved.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to a two-stage damping automobile suspension structure and a locking control method. Background technique [0002] With the improvement of people's living standards and the advancement of automobile research and development, people's requirements for various performances of automobiles are getting higher and higher. The car suspension system has an important influence on the car's ride comfort, driving safety and handling stability. Can drive smoothly. [0003] The current suspension types are mainly divided into passive suspension and active suspension. Although the traditional passive suspension, that is, the spring-damper two-element structure can meet the basic performance requirements of the car, it is difficult to improve and break through due to its structural limitations. Although active suspension is superior to traditional passive suspension in terms of per...

[0003] The current suspension types are mainly divided into passive suspension and active suspension. Although the traditional passive suspension, that is, the two-element structure of the spring damper can meet the basic performance requirements of the car, it is difficult to improve and break through due to its structural limitations.

Although active suspension is superior to traditional passive suspension in terms of performance, it requires multiple sensors for data detection, resulting in complex structure and high cost, which is not suitable for general promotion
