Definitions
- the invention relates to a suspension for a rail vehicle, in which in the wheel area between the wheel axle and a frame as primary suspension and / or between the frame and a spring element is provided to the vehicle body as secondary suspension, which a hydraulic unit with a working cavity, the volume of which is opposed by two movable end pieces is changeable, and has a spring gas container which by a movable separator is divided into a gas space and a hydraulic space, the working cavity is connected to the hydraulic room and these two rooms with a liquid are filled, but the gas space is filled with a gas.
- EP 0 568 042 A1 describes a spring element of the type mentioned at the beginning for a Bogie, in which hydropneumatic spring elements, consisting of cylinder and Pistons with assigned liquid and gas volumes are provided.
- hydropneumatic spring elements consisting of cylinder and Pistons with assigned liquid and gas volumes are provided.
- the gas volume can be arranged in the spring elements, or there are gas accumulators on the spring elements connected as external elements, with a part of the liquid volume in the gas storage and the gas volume is included.
- a disadvantage of this suspension system is that it can roll during practical operation. and tilting movements of a rail vehicle can not compensate for what with a high Derailment risk.
- DE 196 51 138 A1 describes a suspension consisting of two connected in parallel Spring systems with three springs arranged parallel to each other, one Spring is designed as a hydropneumatic spring, which is a bellows made of elastomeric material has a support plate with the upper part using fastening means a rolling piston connects, the hydropneumatic spring of one system with the hydropneumatic spring of the second spring system by means of an overflow channel pressure equalizing connected is.
- a second spring is provided around each hydropneumatic spring, which extends from the support plate to the base of the rolling piston, one third spring is installed in the rolling piston.
- DE 907 150 C describes a suspension of vehicles in which the wheel load is above a liquid pressure medium is transferred to several air cushions connected in series, which gradually come into effect, the air cushions being filled with air Bubbles are formed from an elastic material and a wall part as a sealing surface is trained.
- a hydropneumatic spring device which consists of hydraulic cylinder units, one between individual spring elements Pipeline is provided which cooperates with a pressure receptacle is partially filled with gas, which can be compressed by the liquid.
- a pressure receptacle is partially filled with gas, which can be compressed by the liquid.
- For support the hydropneumatic spring device are made of further helical springs Metal provided. The presence of additional metal springs prevents space-saving, arrangement of the spring elements adapted to the structural conditions of the rail vehicle.
- US 4,245,563 A describes a combination of helical metal springs and one hydropneumatic suspension, the nested and partially open cylinders has, wherein a liquid exchange is possible between the cylinders.
- the large installation volume is also a disadvantage here.
- EP 0 321 324 A1 presents a hydropneumatic suspension which has a cylinder has, which is connected by a support arm to a wheel, an am Car body attached piston is provided, the axis of which is guided in a cylinder bore and that is connected to a hydropneumatic pressure accumulator.
- suspension does not meet the requirements for rail vehicles because it is due to their very special embodiment can only be used for motor vehicles.
- This task is based on a spring system of the type mentioned solved that the working cavity of two or more hydraulic units via a synchronizing unit communicates with a common spring gas container.
- the synchronization unit has a cavity, which by a freely displaceable piston in at least three separate sub-cavities are separated, at least one of these sub-cavities is connected to a spring gas container, and at least two of the other partial cavities are each connected to at least one working cavity of a spring element.
- each working cavity of a hydraulic unit has exactly one Has spring gas container.
- the spring element 1 shown in FIG. 1 has a hydraulic unit 2 with two end pieces 3a and 3b, which are sealingly connected to one another via a bellows 4.
- a working cavity 5 is limited, which accordingly the distance between the end pieces 3a and 3b can be changed.
- the rolling bellows 4 rolls according to the Reduction of the distance between the two end pieces 3a and 3b on what is generally used as a rolling cylinder trained end piece 3b.
- the working cavity 5 is connected via a line 7 a spring gas container 8 in connection.
- the spring gas container 8 is usually a membrane formed part 9 divided into a gas space 10 and a hydraulic space 11.
- the Hydraulic chamber 11, the line 7 and the working cavity 5 are incompressible Fluid, the hydraulic fluid, the gas space 10, however, filled with a gas.
- an end stop 12 designed as a rubber buffer on the inside of the end piece 3b recognize which for the case of tip strokes or as an emergency spring for the case is thought that the spring mechanism due to, for example, the loss of Hydraulic fluid fails.
- a hydraulic fluid generally an oil
- gas is considered as Spring medium chosen because it shows a progressive behavior, and thus an optimal use the travel is guaranteed.
- FIG. 2 shows a chassis frame 13, a wheelset bearing 14 and a wheel 15 of a rail vehicle shown.
- the installation of a spring element 1 according to FIG. 1 is schematic between the chassis frame 13 and the wheelset bearing 14 indicated.
- the spring element 1 With an expedient Embodiment is the spring element 1, although it only has to transmit pressure forces in usually both with the chassis frame 13 and with the housing of the wheelset bearing 14 screwed.
- 3 to 5 show roughly schematic spring systems in which the hydraulic units 2a-2d of spring elements 1 attached in the area of wheels 15 of a rail vehicle are, the working cavities of the hydraulic units logically interconnected are.
- the embodiment in which each working cavity has one is not shown has its own spring gas container, so the hydraulic units are not coupled to each other are.
- springing of each wheel is possible separately, however can not pitch or roll independently of diving movements without additional Stabilizing device are suspended.
- Fig. 3 shows a spring system in which a rolling movement of the vehicle is largely suppressed by the fact that the working cavities of two hydraulic units 2a and 2b, which in the area of wheels 15 on opposite sides of an axis are attached, via lines 16a and 16b and a synchronization unit 19a to one common spring gas container 8a are coupled.
- the synchronization unit 19a its mode of operation is discussed in detail below, the task falls to - in In this case, two - work cavities to couple so that a compression of the one spring element immediately to deflect the spring element coupled to it or exactly taken to compress the interconnected hydraulic units 2a and 2b leads, whereby a roll motion is avoided.
- this pairing of opposite hydraulic units on necessary for each axis is of course.
- the working cavities are hydraulic units 2a and 2d and 2b and 2c of a vehicle side via a common line 17a and 17b connected with each other.
- the hydraulic units on one side are not above one Synchronizing unit in contact with each other.
- hydraulic units 2a and 2c and 2b are diagonally opposite one another and 2d via lines 18a, 18c and 18b, 18d and via a synchronization unit 19a, 19b coupled to a common spring gas container 8a.
- a cavity 20 by a freely movable Piston 21 separated into three independent sub-cavities 22-24.
- the subareas 22 and 23 are connected via lines 25 and 26 to the working cavities of two hydraulic units, Subarea 24 via a line 27 to the hydraulic chamber of a spring gas container in connection. Both the hydraulic units and the spring gas tank are not here shown.
- a compression of the two end pieces 3a caused by a force effect and 3b of a hydraulic unit 2 as in FIG. 1 leads to the volume displaced thereby flows into a partial cavity, for example partial cavity 22 of the synchronizing unit 19.
- level control by means of a pump and height regulator is provided, via which achieves an unchangeable height of the vehicle body regardless of the load can be.
