Embodiment Construction

[0046] The following directions "left" and "right" are based on figure 1 described as a basis.

[0047] Such as figure 1 A hydro-pneumatic suspension system with active volume control is shown, including:

[0048] Hydraulic cylinder A1, a rod piston body 10 is arranged inside the hydraulic cylinder A1, and the rod piston body 10 dynamically seals the hydraulic cylinder A1, and divides the hydraulic cylinder A1 into the first oil storage for storing oil A space 1a and a first gas storage space 1b for storing gas, a part of the piston rod of the rod piston body 10 is located in the first gas storage space 1b. exist figure 1 Among them, the first oil storage space 1a is located on the right side, the first gas storage space 1b and the rod piston body 10 are located on the left side, and optionally there is electromagnetic adjustable damping between the rod piston body 10 and the hydraulic cylinder A1. Same as the prior art, there is no seal between the first gas storage space...

Abstract

The invention relates to the field of hydro-pneumatic suspension systems of vehicles, in particular to a hydro-pneumatic suspension system capable of realizing active volume control and a vehicle. The hydro-pneumatic suspension system comprises a hydraulic cylinder body A, a hydraulic cylinder body B, a gas energy accumulator, a bidirectional throttling structure and an active expansion and contraction device, wherein the active expansion and contraction device is used for actively controlling movement of a rod-less piston body in the hydraulic cylinder body B. A vehicle body levelness detection sensor sends a detected inclination angle of the vehicle to a vehicle ECU; the vehicle ECU controls the active expansion and contraction device to push and pull the moving amount and the moving direction of the rod-less piston body in the hydraulic cylinder body B according to a preset expansion and contraction amount; the active expansion and contraction device pushes and pulls the rod-less piston body to further actively adjust the position of the rod-less piston body on the basis of passive adjustment of the hydro-pneumatic suspension system, so that the shortcoming of purely passive adjustment of the hydro-pneumatic suspension system for the balance of a vehicle body is overcome.

Description

technical field [0001] The present application relates to the field of oil-pneumatic suspension systems for vehicles, in particular to an active volume-controlled oil-pneumatic suspension system and a vehicle. Background technique [0002] The suspension system is the general term for the force transmission connection device between the frame and the wheel of the vehicle. Its main function is to buffer the impact force transmitted from the uneven road to the frame or body, and attenuate the vibration caused by it, so as to ensure the smooth running of the vehicle. , the suspension system determines the stability, comfort and safety of the vehicle, and is one of the most critical components of a modern vehicle. At present, leaf springs and rubber hollow springs are still mostly used in trucks below 30t. More and more heavy-duty vehicles with a load of more than 30 tons use oil-air suspension. Oil-air suspension can improve the working conditions of the driver, increase the a...
