Description
Technical field
The present invention relates to a kind of automobile chassis suspension system, especially a kind of pneumatic cylinder.
Background technique
The pneumatic cylinder of existing automobile meets vehicle and is required to realize chassis clearance adjustment, cannot change resistance
Buddhist nun；Damping can be changed, can not achieve chassis clearance adjustment.The liftoff height in adjustment chassis of vehicle requirement cannot be realized simultaneously
Degree and two kinds of functions of variable damping.
Summary of the invention
The object of the present invention is to provide a kind of pneumatic cylinders, overcome existing pneumatic cylinder that can only adjust vehicle chassis
Terrain clearance is unable to variable damping or can only variable damping the shortcomings that being unable to adjust vehicle chassis terrain clearance.Novel oil gas suspension cylinder
Design in, hydraulic control is combined with the control technology of magnetorheological fluid, respectively realize hydro pneumatic suspension adjustment vehicle chassis
Terrain clearance and variable damping function.Using this Novel oil gas suspension cylinder, for passing through control in the active suspension system of vehicle chassis
The adjusting of system processed can have the function of adjusting chassis clearance and variable damping simultaneously, adapt vehicle to various road conditions.
In order to solve the above-mentioned technical problem, technical scheme is as follows: a kind of pneumatic cylinder, it is characterised in that:
Including cable, cable connects electromagnetic piston by piston rod, and the both ends of electromagnetic piston are full of magnetorheological fluid, and magnetorheological fluid is logical
It crosses electromagnetic piston to be flowed in electromagnetic piston two sides, piston separates the nitrogen of the magnetorheological fluid in left side and right side, piston rod
It is connect with wheel portion, cylinder body is connect with frame section.
Improvement to above-mentioned technical proposal: the pneumatic cylinder is used for the suspension system of vehicle chassis, and structure type is adopted
With core structure, in piston rod, piston rod and cylinder body are combined into a hydraulic cylinder, rod chamber for magnetorheological fluid and nitrogen closing
With rodless cavity connection.
The utility model has the advantages that
It is an object of the invention to overcome the shortcomings of above-mentioned prior art, a kind of Novel oil gas suspension cylinder is provided for Active suspension
In system, by hydraulic control and magnetorheological fluid control technology, makes it while there is adjustment vehicle chassis terrain clearance and variable resistance
Buddhist nun's function has expanded the function of suspension system, improves vehicle chassis to the adaptability of different road conditions.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Novel oil gas suspension cylinder.
Specific embodiment
Pneumatic cylinder of the present invention as shown in Figure 1, cable 1 connect electromagnetic piston 5, electromagnetic piston 5 by piston rod 2
Both ends be full of magnetorheological fluid 4, magnetorheological fluid 4 can be flowed by electromagnetic piston 5 in 5 two sides of electromagnetic piston, and piston 6 will be left
The magnetorheological fluid 4 of side is separated with the nitrogen 8 on right side, and when installing and using, piston rod 2 is connect with wheel portion, cylinder body 10 and vehicle frame
Part connects, and in vehicle travel process, by the impact of uneven road surface, impact force is transmitted to by piston rod 2 and magnetorheological fluid 4
Piston 6, thus compressed nitrogen 8, nitrogen 8 is absorbed the impact of uneven road surface bring by compression and realizes that shock-absorbing function, electromagnetism are living
The size of current that the mobile speed of plug 5 can then be conveyed to cable 1 by external controller changes the viscosity of magnetorheological fluid, from
And change the movement speed of electromagnetic piston 5, that is, variable damping.The electric current that cable 1 inputs is bigger, and the viscosity of magnetorheological fluid is got over
Greatly, the movement speed of electromagnetic piston 5 is slower；Otherwise the electric current that cable 1 inputs is smaller, and the viscosity of magnetorheological fluid is smaller, electromagnetism
The movement speed of piston 5 is faster.9 two sides of piston are all hydraulic oil 7, and hydraulic oil can circulate in 9 two sides of piston, when vehicle chassis needs
When carrying out height adjustment, hydraulic oil 7 can be controlled from hydraulic fluid port 11 by external hydraulic system and realized in cylinder intracorporal volume: when
When from 11 feed liquor pressure oil 7 of hydraulic fluid port, piston rod 3 is displaced outwardly, and pneumatic cylinder length elongation, vehicle chassis terrain clearance is adjusted
It is high；When under the gravity of vehicle chassis from hydraulic fluid port 11 toward exterior liquid pressure oil 7, piston rod 3 is moved inward, pneumatic cylinder
Length shortens, and vehicle chassis terrain clearance is lowered.
Novel oil gas suspension cylinder is mainly used for the suspension system of vehicle chassis, and structure type uses core structure, magnetorheological
In piston rod 3, piston rod 3 and piston rod 2 mainly realize shock-absorbing function, the electricity inputted by cable 1 for liquid and nitrogen closing
The viscosity that size changes magnetorheological fluid is flowed, to change the damped coefficient of damping, to be adapted to different road conditions.3 He of piston rod
Cylinder body 10 is combined into a hydraulic cylinder, rod chamber and rodless cavity connection, by hydraulic system to oil capacity hydraulic in cylinder body
It controls to change the terrain clearance of vehicle chassis, to improve the passage capacity of vehicle chassis.
It is applied on new oil cylinder when magnetorheological fluid control technology and hydraulic control combine, passes through control system
It adjusts, Novel oil gas suspension cylinder can realize variable damping and adjustment two kinds of functions of vehicle chassis terrain clearance simultaneously.
