Abstract
The utility model discloses a kind of double hydraulic control single lever-type oil hydraulic cylinder, it comprises cylinder sleeve, free-standing piston, lower hydraulic fluid port, piston rod, upper hydraulic fluid port, and free-standing piston is positioned at cylinder sleeve, and lower hydraulic fluid port is positioned at the bottom of cylinder sleeve, upper hydraulic fluid port is positioned at the center of piston rod, and one end and the cylinder sleeve of piston rod are slidably connected.The utility model can lifting vehicle chassis height rapidly, improves passing ability and the reliability of vehicle.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, particularly relates to a kind of double hydraulic control single lever-type oil hydraulic cylinder.
Background technique
The chassis lifting function of modern high end automobile mainly utilizes and regulates the air quantity of pneumatic spring and pressure, thus reaches the object of chassis lifting.But mix with anti-vibration function realization substantially, at the volley, the reliability of its height is just difficult to ensure, and ageing due to what inflate, and the amplitude of general lifting is little, maximum tens centimetres.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of double hydraulic control single lever-type oil hydraulic cylinder, its rapid lifting vehicle chassis height, improves passing ability and the reliability of vehicle.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of double hydraulic control single lever-type oil hydraulic cylinder, it is characterized in that, it comprises cylinder sleeve, free-standing piston, lower hydraulic fluid port, piston rod, upper hydraulic fluid port, stand alone type piston is positioned at cylinder sleeve, lower hydraulic fluid port is positioned at the bottom of cylinder sleeve, upper hydraulic fluid port is positioned at the center of piston rod, and one end and the cylinder sleeve of piston rod are slidably connected.
Preferably, described lower hydraulic fluid port and upper hydraulic fluid port are all oil inlet and outlets.
Preferably, the oil filling amount of described lower hydraulic fluid port determines the height of free-standing piston.
Preferably, the oil filling amount of described upper hydraulic fluid port determines the relative height of piston rod and free-standing piston.
Preferably, the diameter of one end of described piston rod is greater than the diameter of the other end of piston rod.
Preferably, described free-standing piston can slide up and down in cylinder sleeve, and the top and the bottom of free-standing piston are oil pocket.
Preferably, the piston of described piston rod and free-standing piston are all equipped with seal arrangement.
Positive progressive effect of the present utility model is: the rapid lifting vehicle chassis height of the utility model, improves passing ability and the reliability of vehicle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model double hydraulic control single lever-type oil hydraulic cylinder.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model double hydraulic control single lever-type oil hydraulic cylinder comprises cylinder sleeve 1, free-standing piston 2, lower hydraulic fluid port 3, piston rod 4, upper hydraulic fluid port 5, stand alone type piston 2 is positioned at cylinder sleeve 1, lower hydraulic fluid port 3 is positioned at the bottom of cylinder sleeve 1, upper hydraulic fluid port 5 is positioned at the center of piston rod 4, and one end and the cylinder sleeve 1 of piston rod 4 are slidably connected.Lower hydraulic fluid port 3 and upper hydraulic fluid port 5 are all oil inlet and outlets.The diameter of one end of piston rod 4 is greater than the diameter of the other end of piston rod 4.Piston and the free-standing piston of described piston rod are all equipped with seal arrangement.Stand alone type piston can slide up and down in cylinder sleeve, and the top and the bottom of free-standing piston are oil pocket.Piston rod is open-core type piston rod.
The oil filling amount of lower hydraulic fluid port determines the height of free-standing piston, and the oil filling amount of upper hydraulic fluid port determines the relative height of piston rod and free-standing piston, and the oil filling amount of the oil filling amount and lower hydraulic fluid port that namely go up hydraulic fluid port determines the height of piston rod jointly.The change (can not often change) of lower hydraulic fluid port oil filling amount can promote the change of free-standing piston position, also just changes the basis of piston rod, thus changes vehicle chassis height, for obtaining fast rising or falling speed and amplitude provides technical support.And the change of upper hydraulic fluid port oil filling amount is dynamic, be gone to change by the control overflow of anti-vibration.
If the utility model double hydraulic control single lever-type oil hydraulic cylinder all installed by all wheels, under the control of corresponding hydraulic pressure, can lifting vehicle chassis height within the specific limits, improve the passing ability of vehicle, and can provide a kind of possible for the height of dynamic adjustments anti-vibration and hardness.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
