Abstract

The invention relates to an external electro-hydraulic combined type vehicle posture adjusting unit. The external electro-hydraulic combined type vehicle posture adjusting unit is mainly composed of amain body executing mechanism, an additional oil chamber and a driving transmission mechanism. The driving transmission mechanism makes the main body executing mechanism realize vehicle posture adjustment; and oil in an additional oil chamber ensures that an inner cavity of the main body executing mechanism is filled with the oil, the inner cavity of the main body executing mechanism is closed when the vehicle posture adjustment is completed, and a force borne by the vehicle posture adjustment unit is borne by the oil in the inner cavity of the main body executing mechanism due to a fact thata feeding mode of a ball screw in the main body executing mechanism has no self-locking characteristic. Due to the fact that the adjusting units are independently arranged at upper ends of the corresponding elastic damping elements in a suspension system, the vehicle posture adjusting function is achieved by changing the lengths of the units, and the problems that a traditional vehicle posture adjusting system is complex in structure, large in occupied space in a vehicle, poor in maintainability, low in reliability and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery, and in particular relates to an external electro-hydraulic composite vehicle attitude adjustment unit. Background technique [0002] In view of the complex working environment of armored vehicles and the large change between empty and full loads, in order to improve their terrain adaptability, it is usually necessary to add a hydraulic vehicle attitude adjustment system. The hydraulic vehicle attitude adjustment system of traditional armored vehicles places the hydraulic source, drive system, valve block and pipeline inside the vehicle body, and adjusts the vehicle attitude by adjusting the oil in the oil-gas spring in the suspension system connected to it. Although this method has the advantages of fast response speed and high adjustment accuracy, it has problems such as complex structure, large space in the car, poor maintainability and low reliability.
