Description
Technical field
The utility model is related to a kind of automobile chassis suspension system, especially a kind of pneumatic cylinder.
Background technology
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.
Invention content
The purpose of this utility model is to provide a kind of pneumatic cylinder, overcomes existing pneumatic cylinder that can only adjust vehicle
Chassis 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 is outstanding
In the design for hanging cylinder, hydraulic control is combined with the control technology of magnetorheological fluid, realizes the adjustment vehicle of hydro pneumatic suspension respectively
Chassis clearance and variable damping function.Using this Novel oil gas suspension cylinder, in the active suspension system of vehicle chassis, leading to
The adjusting of control system is crossed, can have the function of adjusting chassis clearance and variable damping simultaneously, adapt vehicle to various roads
Condition.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows:A kind of pneumatic cylinder, feature exist
In:Including cable, cable connects electromagnetic piston by piston rod, and the both ends of electromagnetic piston are full of magnetorheological fluid, magnetorheological
Liquid is flowed by electromagnetic piston in electromagnetic piston both sides, and piston separates the nitrogen of the magnetorheological fluid in left side and right side, living
Stopper rod is connect with wheel portion, and 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 unicom.
Advantageous effect:
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, a kind of Novel oil gas suspension cylinder is provided and is used for
In active suspension system, by hydraulic control and magnetorheological fluid control technology, makes it while there is the adjustment liftoff height of vehicle chassis
Degree and variable damping function, have expanded the function of suspension system, have improved adaptability of the vehicle chassis to different road conditions.
Description of the drawings
Fig. 1 is the structural schematic diagram of Novel oil gas suspension cylinder.
Specific implementation mode
The utility model pneumatic cylinder as shown in Figure 1, cable 1 connect electromagnetic piston 5, electromagnetism by piston rod 2
The both ends of piston 5 are full of magnetorheological fluid 4, and magnetorheological fluid 4 can be flowed by electromagnetic piston 5 in 5 both sides of electromagnetic piston, piston
6 separate the magnetorheological fluid 4 in left side and the nitrogen 8 on right side, and when installing and using, piston rod 2 is connect with wheel portion, cylinder body 10 with
Frame section connects, and in vehicle travel process, is impacted by uneven road surface, impact force passes through piston rod 2 and magnetorheological fluid 4
It is transmitted to piston 6, to compressed nitrogen 8, nitrogen 8 realizes shock-absorbing function, electricity by compressing to absorb the impact that uneven road surface is brought
The size of current that the speed that magnetic piston 5 moves can then be conveyed to cable 1 by external controller changes the viscous of magnetorheological fluid
Degree, to change the movement speed of electromagnetic piston 5, that is, variable damping.The electric current that cable 1 inputs is bigger, magnetorheological fluid
Viscosity is bigger, and 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 got over
Small, the movement speed of electromagnetic piston 5 is faster.9 both sides of piston are all hydraulic oil 7, and hydraulic oil can circulate in 9 both sides of piston, work as vehicle
When chassis needs to carry out height to adjust, volume of the hydraulic oil 7 in cylinder body can be controlled from hydraulic fluid port 11 by external hydraulic system
To realize:When from hydraulic fluid port 11 into hydraulic oil 7, piston rod 3 is displaced outwardly, and pneumatic cylinder length elongation, vehicle chassis is liftoff
Height is raised;When under the gravity of vehicle chassis from hydraulic fluid port 11 toward exterior liquid pressure oil 7, piston rod 3 moves inward, oil
Gas suspension 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 unicom, by hydraulic system to hydraulic pressure oil capacity in cylinder body
Control changes the terrain clearance of vehicle chassis, passes through performance with improve 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 vehicle chassis two kinds of functions of terrain clearance simultaneously.
