The invention belongs to the technical field of vehicle suspensions, and particularly relates to a linear electromagnetic pump drive-by-wire suspension actuator and a control method. The linear electromagnetic pump drive-by-wire suspension actuator comprises an actuator cylinder body, an electromagnetic linear module, a double-acting linear reciprocating pump and a three-position four-way reversing valve. The actuator cylinder body comprises an inner cylinder barrel, an outer cylinder barrel, a piston, a piston rod, a guide device, a rod cavity connector, a rodless cavity connector and a bottom valve body. The electromagnetic linear module, the double-acting linear reciprocating pump and the three-position four-way reversing valve are mounted outside the outer cylinder barrel; compared with a traditional drive-by-wire suspension, the drive-by-wire suspension actuator driven by the linear electromagnetic pump has the advantages that the response speed is higher, the accuracy is higher, and the accuracy and the response speed are better; the suspension intelligent control system realizes a somatosensory entertainment mode in a vehicle parking state; compared with a traditional suspension, the active vibration reduction performance is improved, and the entertainment function of an automobile in a cab based on the active suspension is enriched.

    本发明属于车辆悬架技术领域,具体涉及一种直线电磁泵驱动线控悬架作动器及控制方法;直线电磁泵驱动线控悬架作动器包括作动筒本体、电磁直线模块、双作用直线往复泵和三位四通换向阀;作动筒本体包括内缸筒、外缸筒、活塞、活塞杆、导向装置、有杆腔接口、无杆腔接口以及底阀体;电磁直线模块、双作用直线往复泵和三位四通换向阀安装在外缸筒外;本发明公开的一种直线电磁泵驱动线控悬架作动器相比于传统线控悬架有更快的响应速度和更高的准确度,基于更优的准确度和响应速度;悬架智控系统实现了车辆停车状态下的体感娱乐模式;相比传统悬架既提升了主动减振性能,又丰富了汽车基于主动悬架的驾驶舱内娱乐功能。
