The invention discloses a height adjustment device of an independent hydro-pneumatic suspension vehicle. The height adjustment device mainly comprises a position change oil cylinder, a positioner, a control mechanism, a lever, a vibration reduction mechanism, a rocker arm mechanism and a suspension mechanism, wherein the upper end of the position change oil cylinder, the lower end of the positioner and one end of the lever are intersected at one point and are connected, the control mechanism is connected with the lever through an adapter rod, the other end of the lever is connected with one end of the vibration reduction mechanism, the other end of the vibration reduction mechanism is connected with one end of the rocker arm mechanism, the rocker arm mechanism and the suspension mechanism are connected and rotate at the same angle in the same direction, a positioning groove is formed in the positioner, and the position change oil cylinder pushes the positioner to perform positioning through the positioning groove. The height adjustment device has the advantages of being simple in structure, easy to install, quick to adjust, high in accuracy, reliable in work and strong in environmental suitability, is suitable for height adjustment of the independent hydro-pneumatic suspension vehicle and can be also popularized to a hydro-pneumatic or pneumatic non-independent suspension vehicle.
Description
technical field [0001] The invention relates to the technical field of height adjustment devices, in particular to a height adjustment device for a vehicle with oil and gas independent suspension. Background technique [0002] In order to meet the cross-country requirements of military vehicles with oil and gas independent suspension for crossing trenches, climbing vertical walls, and wading, as well as the different height requirements for road, railway, and air transportation, it is necessary to adjust the height of the vehicle. The existing height adjustment device usually adopts the coaxially installed angle sensor as the detection element, and the electromagnetic reversing valve is the oil filling and discharging control element. Although the structural layout is relatively simple, the installation accuracy is high, the control system is complicated, and the reliability is low. , poor environmental adaptability, etc., cannot well meet the harsh environment and high reli...
