Definitions
- the invention relates to a soil compaction device according to the preamble of claim 1.
- Such vibration plates usually consist of a drive having upper mass and a lower mass, which consists essentially of a Ground contact plate and a vibration excitation device driven by the drive consists.
- the vibration exciter usually it is one, two or four unbalance exciters that arranged on one or two excitation shafts driven by the drive are.
- the upper mass is in several places with the lower mass by spring damper units, z. B. rubber buffer coupled.
- From DE-B-1 168 350 is a soil compaction device with a Upper mass, a ground contact plate and a vibration exciter having lower mass, and with the upper mass with the Known undersize at several points spring units.
- the spring preload can be used for piston-cylinder units belonging to the upper mass change the associated spring unit, whereby the The contact pressure of the floor contact plate on the floor can be adjusted can.
- the upper mass is essentially a road roller educated.
- EP-A-0 142 198 shows a comparable soil compaction device, in which the spring preload of spring units of one Piston-cylinder unit for changing the contact pressure of the ground contact plate can be adjusted.
- From US-A-3,802,791 is a soil compaction device with a an upper mass carrying a vibration exciter device and a Bottom contact plate having known sub-mass.
- the one at the top Vibrations are generated via an intermediate plate and spring units transferred to the lower mass.
- additional spring damper units installed, their spring preload by tilting the upper mass in the forward or reverse direction is changeable.
- the soil compacting device can only be steered by tugging on a guide bracket.
- the invention has for its object a vibration plate with a Specify directional control that is structurally simple yet highly effective is.
- the asymmetrical with respect to the direction of travel Change the damping properties or characteristic values of at least a damping element, for example on the right or left Side of the vibration plate can be arranged around the yaw moment Vertical axis of the plate is generated so that the plate is in the corresponding Direction turns.
- the vibration plate can therefore be operated via the steering device during driving depending on the operator's request Be turned in the direction.
- At least one Spring damper unit is a damping material made of an electroviscous Fluid on through the steering device with a variable electrical Voltage can be applied. Change electroviscous liquids their viscosity depending on an electrical effect on them Tension. When using an electroviscous liquid in one Damper it is possible to completely reduce the damping characteristics of damping to vary rigidly and therefore, depending on the voltage applied, set the desired damping value.
- One or more such dampers are preferably used together with Rubber buffers are used, the upper mass with the lower mass in known Pair Wise.
- the electroviscous dampers are parallel to the Rubber buffers arranged.
- Yet another embodiment of the invention is characterized in that that the spring damper unit, its spring and / or damping characteristics can be changed, has several springs and / or dampers, the one by the steering device via an actuator can be switched off.
- This makes it possible, e.g. the coupling point of the Rubber buffer on the lower or upper mass by interposing Vary springs or other rubber buffers. It is also possible individual rubber buffers completely by means of a magnetic latch bridge or switch on another rubber buffer.
- An upper mass 1 consists essentially of a drive 2, which on a Frame 3 attached and covered by a protective frame 4. On the frame 3 is also a guide drawbar 5 with a steering lever 6 appropriate.
- the upper mass 1 is on its frame 3 by means of several, usually four rubber buffers 7 attached to a sub-mass 8, which essentially from a ground contact plate 9 and a vibration exciter 10 exists. Since the vibration excitation device 10 and the one driving it Drive 2 are known, their detailed description is omitted.
- the rubber buffers 7 are usually between the frame 3 and the ground contact plate 9 used.
- damping elements which act as damping material contain an electroviscous liquid (e.g. RHEOBAY®).
- electroviscous Liquids are characterized in that their viscosity depends is changeable by an applied voltage. So it is e.g. possible, the electroviscous fluid in the damper is largely free of resistance to flow, so the damping effect is low. on the other hand the viscosity can also be increased significantly by applying the voltage become, which leads to an increase in the damping effect.
- the change in the voltage to be applied to the electroviscous damper is by pressing the steering lever 6, which with a suitable, not shown control unit is connected.
- the control unit generates and varies the voltage as desired.
- An embodiment is particularly preferred in which on both sides, i.e., seen in the direction of travel, at least one electroviscous on the left and right Damper is arranged. Change the fluids in both dampers with appropriate actuation of the steering lever 6 its viscosity, so that on the two sides achieved different damping effects and the desired Yaw moment can be generated around the vertical axis of the vibration plate can.
- the use of known oil pressure shock absorbers is also possible with variable cross-sections that can be influenced from the outside possible.
- the coupling point of the rubber buffer on the lower or Upper mass can be varied, for example by interposing others Rubber buffers or springs. Switching then takes place either by means of an actuator or an electromagnetic actuator which by Pressing a latch either completely bridges the rubber buffer or switch on another rubber buffer.
- Still another embodiment of the invention is based on the Guide drawbar completely dispensed with. Instead, remote control used, which enables the operator to use the vibrating plate operate from a distance and therefore outside the danger zone. Furthermore, the operator is no uncomfortable vibrations exposed more. However, this not only has the advantage of increasing comfort: Because of the guide drawbar and the previously used, expensive Hydraulics can be dispensed with, are significant manufacturing costs save.
