Embodiment
As shown in Figure 1, the whole device of apparatus of the present invention is placed in a closed spring strut 14, comprises a connecting rod fixed mount 7, the many groups of connection rod set be made up of three connecting rods, upper and lower two movable disk 1,6.The connection rod set that the installation site of more than three groups or three groups is identical, measure-alike, each connection rod set has three connecting rods, three connecting rods are divided into upper, middle and lower three, upper connecting rod 2 is fixed on connecting rod fixed mount 7 upper end, and movable disk 1 is placed with on upper roller 11,11 roller in upper connecting rod 2 upper end, lower link 5 is fixed on connecting rod fixed mount 7 lower end, lower link 5 lower end is with lower roller, and place lower movable disk 6 below lower roller, intermediate connecting rod 4 connects upper and lower strut.Connecting rod fixed mount 7 is similar to a drum type, middle is empty, the fixing upper connecting rod 2 in connecting rod fixed mount 7 upper surface, lower link 5 is fixed in lower surface, and the perforate of connecting rod fixed mount lower planes, upper movable disk 1 is placed on above the upper roller 11 of connecting rod 2, and lower movable disk 6 is placed on below the lower roller of lower link 5.
Specifically, operating mechanism disc spring energy storing device of the present invention comprises the connecting rod fixed mount 7 of hollow, multiple connection rod set, upper movable disk 1 and lower movable disk 6, disc spring 10 and spring pull bar 13.In embodiments of the present invention, each connection rod set comprises connecting rod 2, middle connecting rod 4 and lower link 5, described upper connecting rod 2 and lower link 5 are fixed on the upper and lower side of connecting rod fixed mount 7 respectively by the first and second rotating shafts 3,8, and the two ends of middle connecting rod 4 connect connecting rod 2 and lower link 5 respectively.Described spring pull bar 13 is by pulling force by upper movable disk 1, lower movable disk 6, fixed mount 7, and disc spring 10 links together.
The end of described upper connecting rod 2 and lower link 5 is respectively arranged with roller 11 and lower roller 12, when spring pull bar 13 is by pulling force, upper connecting rod 2 upper end is contacted by upper roller 11 with upper movable disk 1 and rolls above, lower link 5 lower end is contacted with lower movable disk 6 by lower roller 12, and acts in disc spring 10.
In the example in fig 1, the mode of three groups of connecting rods is taked.In implementation process, in whole process, connecting rod fixed mount 7 is fixed by pressing plate 9.Lower movable disk 6 is below close to disc spring 10, is close to lower roller 12 above, and upper movable disk 1 is close to roller 11 below, above fixing spring pull bar 13(also can be chain).Because three groups of connecting rod installation sites are identical, measure-alike, therefore three upper rollers 11 of upper connecting rod 2 upper end of three connection rod set are all in same level, and three lower rollers 12 of three lower link 5 lower ends are all in same level.When energy storage, spring pull bar 13 moves downward, and pulls movable disk 1 to move downward together thereupon, upper movable disk 1 passes to upper roller 11 power, and like this, power is delivered to lower roller 12 by connection rod set, lower roller 12 depresses movable disk 6, and lower movable disk 6 presses disc spring 10, realizes energy storage.During disc spring fault offset, contrary with said process.Further, described disc spring 10 is provided with spring guide sleeve 15 and leads for disc spring.
As shown in Figure 2, be the fixed form of connection rod set and connecting rod fixed mount 7.In disk spring energy storage process, upper connecting rod 2 rotates clockwise, and middle connecting rod 4 counterclockwise movement, lower link 5 rotates clockwise.In disc spring energy release process, upper connecting rod 2 rotates counterclockwise, and middle connecting rod 4 clockwise movement, lower link 5 rotates counterclockwise.In implementation process, in will keeping all the time, connecting rod 4 changes in the same side of vertical direction with the angle of vertical direction.
As shown in Figure 3, be working state schematic representation when device is implemented.In the present example, upper movable disk is pulled S
2time, disc spring compression S
1.Like this, the object that when working by disc spring, stroke amplifies just is achieved.
