Abstract

The invention discloses a vehicle attitude adjustment system using precise transmission control, which comprises a controller (1) and four vehicle attitude adjustment servo execution units, wherein the four vehicle attitude adjustment servo execution units are connected with the controller (1) and are respectively Corresponding to the arrangement of each wheel position; the four vehicle attitude adjustment servo execution units have the same structure, each vehicle attitude adjustment servo execution unit includes an oil and gas spring (5), and the oil and gas spring (5) is arranged on the chassis corresponding to each wheel position, The controller 1 controls the charging and discharging of the oil-gas spring (5) to realize the lifting and lowering of the chassis. Compared with the traditional hydraulic system, the system adopts the electric cylinder instead of the hydraulic pump station to provide power for the system, cancels the overflow unit in the traditional hydraulic system, and has higher energy utilization rate.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension adjustment, and relates to a vehicle attitude adjustment system utilizing precise transmission control. Background technique [0002] The existing suspension devices of wheeled armored vehicles in my country usually use leaf springs or coil springs as elastic elements. The non-adjustable spring rate and body posture make it difficult to greatly improve the off-road performance of the vehicle. In recent years, suspension devices using gas springs as elastic elements have been widely used in civil and military vehicles. A set of control systems in addition to gas springs can be used to adjust the suspension stiffness and body posture of the vehicle. Therefore, the adjustable oil-gas spring technology has become a hot spot in the future research and application of armored vehicles. [0003] In order to further improve the off-road driving performance of wheeled armored vehicles, it is ne...
