Pneumatic spring has: top plate 1, and it is installed on the vehicle body of vehicle; Lower panel 2, the below that it is positioned at top plate is configured in the chassis side; The flexible member 3 of tubular, it disposes with lower panel 2 across top plate 1; And elastomeric stopper 4, it is installed between lower panel 2 and the chassis.In addition, in Fig. 1 and Fig. 3～Fig. 5, the state after flexible member 3 interior air are discharged from is shown.
In this mode of execution, use rubber system bellows as flexible member 3.Flexible member 3 is made up of the range upon range of rubber of the reinforced stock layer that will be embedded with gut threads as the mesosphere; In the upper end portion and the underpart of flexible member 3, be formed with reinforcement edge (bead) 3a of portion, the 3b of the heavy wall that forms strengthening coiling reinforced stock layer on the edge core.That is, flexible member 3 has: strengthen the edge 3a of portion, 3b, it is formed on place, two end part up and down; And the bendable portion 3c of tubular, it is by being formed on that the range upon range of rubber of strengthening between the edge 3a of portion, the 3b constitutes and thin-walled ground forms.
As shown in Figure 1, top plate 1 has: discoid support plate 5, and it is a metallic; The reinforcement edge supporting portion 6 of drum, it is positioned at the central part of support plate 5, protrudes to lower panel; And protection rubber layer 7, it is positioned on the lower surface of support plate 5, is arranged on strengthening edge supporting portion 6 and compares the part place in the radial direction outside, and in strengthening edge supporting portion 6, embedding has the edge of the reinforcement 3a of portion.The central authorities of plate 1 are formed with the vent hole 10 of the air pressure inside that is used to regulate flexible member 3 in the above.
Like Fig. 1 and shown in Figure 2; Elastomeric stopper 4 has rubber layer that is made up of vulcanized rubber 11 and the back-up coat 12 alternately laminated range upon range of rubber section 15 that form that are made up of steel plate; In the top and the lower end, metal top board 13 and base plate 14 is bonding with range upon range of rubber section 15.Range upon range of rubber section 15 forms the cylindric of heavy wall.
It is discoid that lower panel 2 utilizes metallic material to form, and the top board 13 of elastomeric stopper 4 utilizes secure components such as bolt, nut to be fixed.Top board 13 forms circular.Lower panel 2 also has as the function of strengthening the edge supporting portion, and embedding in the plate 2 below has the edge of the reinforcement 3b of portion.
At the downside of strengthening the edge 3b of portion, rubber base 8 is installed along the shape of strengthening the edge 3b of portion.Rubber base 8 forms ring-type by rubber and reinforcing metalwork.Thus, can keep the durability of flexible member 3 well.
Strengthen edge and bear under portion 6 and the situation of lower panel 2 after the air of the inside of flexible member 3 is discharged (under the situation after the venting), strengthen edge supporting portion 6 and be supported on the lower panel 2, with the function of the safety traffic of guaranteeing vehicle.Be fastened with slip thin plate 9 respectively on the surface of contact that reinforcement edge supporting portion 6 and lower panel 2 contact when venting.
Slip thin plate 9 is made up of the thermoplasticity or the thermosetting synthetic resin that can be shaped as thin and tough and tensile thin plate, uses the little resin of friction factor.Specifically, can enumerate fluorine-type resin, polyethylene and polypropylene etc.In this mode of execution, use the fluorine-type resin thin plate.
The base plate 14 of elastomeric stopper 4 forms discoideus, and centre portion forms with the mode to the top protrusion with limiting part 16 cards hooking part 17 only therein.Hooking part 17 forms conical front end is cut the truncated cone shape that forms, and is fixed under the state in inserting range upon range of rubber section 15.Limiting part 16 is made up of the bolt of band hexagon ring, forms the tapped hole that can screw togather with limiting part 16 at the top of a side hooking part 17.And limiting part 16 forms the restriction posture when only blocking with hooking part 17, and limiting part 16 is forming the releasing posture when hooking part 17 unloads.
As shown in Figure 2, the central part of plate 2 is formed with through hole 18 below, and when limiting part 16 formed the restriction posture, limiting part 16 was held with the state that inserts in the through hole 18.At this moment, not under the state of the power of exposure level direction, limiting part 16 is as shown in the figure at pneumatic spring, and the inner peripheral surface with through hole 18 does not contact, and is positioned at the center of through hole 18.
In the pneumatic spring of said structure, under the situation that limiting part 16 and hooking part 17 cards are ended, the air in the flexible member 3 is discharged; As shown in Figure 3; In that top plate 1 is supported under the state on the lower panel 2, will unload with the pipe arrangement that vent hole 10 is connected, vent hole 10 is exposed.And,, from the vent hole 10 of top plate 1 limiting part 16 is carried out charge and discharge operations with respect to hooking part 17 and gets final product as long as use suitable assembly tool.

Through hole 18 forms the slotted hole of comparing the rectangular shape of on the fore-and-aft direction C of vehicle, growing with the left and right directions B of vehicle.Therefore; Form under the situation of restriction posture at limiting part 16; Even like vehicle start the time or when stopping this on the fore-and-aft direction of pneumatic spring active force, limiting part 16 does not contact with through hole 18 yet, can not limit the relative fore-and-aft direction displacement between lower panel 2 and the base plate 14.Thus, can keep good riding comfort to the swing of the fore-and-aft direction of vehicle.
On the other hand; When passing through bend with high speed, act under the situation of stronger power on this left and right directions at pneumatic spring like vehicle; When the relative left and right directions displacement amount of 14 of plate 2 and base plates reaches established amount (in Fig. 2, being length X) below; Limiting part 16 can contact with the inner peripheral surface of through hole 18, limits the displacement more than or equal to established amount, thereby makes non-linearization of spring constant.Thus, in the high speed route, can guarantee high stability.
Be used at vehicle under the situation of low speed route, limiting part 16 formed remove posture.Thus, not only under the situation of active force on the fore-and-aft direction of pneumatic spring, and under the situation of active force on the left and right directions of pneumatic spring, the opposing horizontal direction displacement that lower panel 2 and base plate are 14 can not be limited.Therefore, vehicle can be relaxed effectively, good riding comfort can be kept to the swing of direction all around with the swing of low speed when the bend.
As described above said; Through pneumatic spring involved in the present invention is applied in the vehicle; Thereby need not according to the route that goes and the pneumatic spring of resetting time and again only utilizes the posture of switching limiting part that vehicle is applicable on any route in high speed route and the low speed route.
In this mode of execution; Be illustrated with respect to the mode that hooking part 17 can freely be provided with loading and unloading to limiting part 16; But be not limited thereto; For example, also can be that the engagement portion that limiting part is moved on the central shaft CA of vent hole 10 is set, utilize limiting part to switch the restriction posture and remove posture with respect to the position of engagement portion 21.
Specifically; Like Fig. 4 and shown in Figure 5, as limiting part 20, ground same as described above; As long as use the bolt of band hexagon ring, the engagement portion 21 of the tapped hole that moves on the central shaft CA of limiting part 20 at vent hole 10 is got final product being provided with on the base plate 14 to have simultaneously.If the combination of limiting part in this mode 20 and engagement portion 21 is compared with the combination of above-mentioned limiting part 16 and hooking part 17, then the bolt length of the former limiting part 20 is longer, and the degree of depth of the tapped hole of engagement portion 21 forms deeplyer.
Thus, make limiting part 20 rotations through utilizing hexagon wrench 19, and limiting part 20 is gone up and down with respect to engagement portion 21.Specifically; In order to make limiting part 20 form the restriction posture; As long as insert in the through hole 18, for being formed, limiting part 20 removes posture, as long as and limiting part 20 is descended towards base plate 14 and make limiting part 20 rise to limiting part 20 towards top plate 1.In this mode, need not limiting part 20 is taken out to the outside from vent hole 10, can limit posture and the switching of removing posture more simply.
