Definitions
- the invention relates to a vibration damper comprising a piston rod, which merges into a piston rod pin to form a contact shoulder and at this piston rod pin a piston valve leads, which is biased against the contact shoulder of the piston rod. Furthermore, the invention relates to a piston valve for a vibration damper, comprising a piston body, which is placed axially between support disks.
- Vibration dampers are used in motor vehicles mostly in the form of hydraulic-mechanical damper and in particular between a respective vehicle body and the axles of the respective motor vehicle for use.
- a vibration damper then serves on the one hand the prevention of Aufschaukeins and ringing of the vehicle body when excited by the road o- in certain driving conditions, as well as the realization of a rapid decay of an excited by the road vibration of a vehicle wheel. In the latter case, a traction of this vehicle wheel is always guaranteed.
- Vibration dampers are usually designed as telescopic shock absorbers in the form of one or two rohrdämpf NEN, wherein a damping effect by the displacement of a damping medium, usually in the form of a hydraulic fluid, is achieved. This displacement takes place via a piston valve, which is equipped with mostly several passages for the damping medium. To define characteristics of the vibration damper resistances are opposed to the flow of the damping medium, which are often present in the form of valve disks which are biased against a valve seat and cover openings of the passage openings until reaching a defined pressure. In order to avoid damping force scattering in series production of vibration dampers, however, it is always necessary to ensure a constant, defined tension of the valve disks in the course of assembly.
- DE 10 2010 040 458 A1 discloses a vibration damper, in which a piston rod leads to a piston rod end on a piston valve.
- the piston valve is biased by a fastening nut against a contact shoulder of the piston rod, which is formed in the transition from an outer diameter of the piston rod to the piston rod pin.
- the piston valve comprises a piston body, which is traversed axially with passage openings, wherein the passage openings are each coverable via an opening via valve discs. Within the piston valve, the piston body is then placed together with the valve discs axially between support discs.
- a vibration damper comprises a piston rod, which merges with the formation of a contact shoulder in a piston rod pin and thereby performs a piston valve on this piston rod pin.
- the piston valve is then biased against the abutment shoulder of the piston rod.
- the piston rod pin is configured at one axial end of the piston rod and provided on the part of the axial end with an external thread on which a fastening nut can be placed with an internal thread in order to bias the piston valve against the abutment shoulder can.
- the abutment shoulder is defined by a shoulder over which the piston Rod reduced from a previous outer diameter to the outer diameter of the piston rod pin.
- the abutment shoulder is present as a substantially axial, annular abutment surface for the piston valve.
- axial is to be understood as meaning an orientation in the direction of a longitudinal central axis of the piston rod or of the piston valve
- radially means an orientation in the direction of a radius of the piston rod or of the piston valve
- the invention now the technical teaching that axially between the contact shoulder of the piston rod and the piston valve, a shim is placed, which compared to the piston rod and / or an immediately following component of the piston valve of a material with a lower yield strength is made.
- a shim is provided in the axial direction between the contact shoulder of the piston rod and the piston valve whose material is weaker in terms of yield strength than the material of the piston rod and / or the material of an immediately following component of the piston valve.
- Such a design of a vibration damper has the advantage that in the series production of the vibration damper Dämpfkraftstreuungen can be reduced, which have their cause in production-related form deviations of the contact shoulder.
- an angle spanned by the piston rod pin and the abutment shoulder is exactly 90 °, whereby deviations from this ideal angle can occur due to tolerances.
- an angle> 90 ° has the disadvantage that, when the piston valve is biased against the contact shoulder, high stresses occur in the contact area of the piston valve on the contact shoulder and, as a result, set losses.
- an angle ⁇ 90 ° leads to an increased tension of the piston valve, in particular of its valve discs, which can lead to a functional impairment of the piston valve.
- the "yield strength" is to be understood as meaning, in particular, a flow limit of a material in the direction of compression and / or drawing, ie, a tension occurring under tensile and / or compressive stress, at which point a plastic deformation of the material begins
- the material of the shim may be designed to be generally weaker in terms of its yield point than that of the piston rod and / or the adjacent component of the piston valve, in which case a bending limit and a torsional limit of the material of the shim would be less than that of the material of the piston rod and / or the material of the immediately following component of the piston valve.
- the yield strength of the material of the shim is chosen to be at least lower than that of the material of the piston rod, but it may also be less than a yield point of the material of the immediately following component of the piston valve.
- the ratio to the material of the piston rod and in this case at least the material of the piston rod selected in the region of the contact shoulder is essential, since otherwise a plastic, form-fitting application of the compensation disc to the contact shoulder compensating for its deformation. softness becomes impossible. If the yield strength of the material of the compensation disc is then also selected to be lower than that of the material of the immediately following component of the piston valve, then the positive engagement of the compensation disc is further improved.
- a vibration damper according to the invention is now mounted by first pushing the shim and at least the immediately following component of the piston valve onto the piston rod journal of the piston rod against the contact shoulder and then tensioning it with a preload against the contact shoulder.
- This preload is above a later assembly preload force.
- the entire piston valve is then preloaded with the mounting biasing force on the piston rod pin.
- at least the component of the piston valve immediately following the balancing disk is pushed onto the piston rod journal during pretensioning with the preload and is subsequently biased against the contact shoulder together with the balancing disk. It can also be arranged on the pin in this biasing but also several components of the piston valve or the complete valve.
- the subsequent biasing and attachment of the piston valve on the piston rod pin with the assembly biasing force is carried out in particular by means of a fastening nut, which is guided for this purpose with an internal thread on an external thread of the piston rod pin.
- a piston valve for a vibration damper comprises a piston body, which is placed axially between support discs.
- the invention also includes the technical teaching that at least one of the support plates on a piston body facing the axial side is at least partially concave curved, while the piston body on each of these at least one support disk facing axial side at least partially convex curved is designed.
- at least one of the support disks is equipped on the side of the piston body with a concave curvature which extends in the radial direction at least over a part of this support disk.
- the piston body has on one of these at least one support disk side facing a curvature, said curvature, however, is convex and extends at least over part of the radial extent of the piston body.
- Such an embodiment of a piston valve has the advantage that due to the shields defined by the curvatures of the at least one support disk and the piston body, a bias of intermediate valve disks against a valve seat on the piston body is increased. Due to this higher bias of the valve discs Dämpfkraftstreuonne between the individual manufactured piston valves and thus also the vibration dampers can be avoided in mass production.
- the support disks and also the piston body of the piston valve are designed with surfaces extending in a straight line in the radial direction.
- the shape of the support disks and the piston body no increase in bias of the valve disks caused on a piston body valve seat, so that it may come in series production of the piston valve to insufficient bias of the valve disks and thus Dämpfkraftstreuonne.
- the piston body is axially penetrated with at least one passage opening, which can be covered at each of an orifice via at least one valve disc.
- a combination of the technical teachings of the independent claims 1 and 7 can now take place by a piston valve according to the independent claim 7 in a vibration damper according to the independent claim 1 is used as a piston valve.
- this vibration damper over a seated between contact shoulder and piston valve shim, and in the region of its piston valve via at least one curved support disk and a curved executed piston body.
- a piston valve of the vibration damper but also be designed such that it comprises a piston body, which is axially interspersed with at least one passage opening.
- the at least one passage opening can be covered in each case via an opening via at least one valve disk, wherein the piston body and the at least one valve disk are placed between support disks on the piston rod journal.
- the support disks and the piston body of the piston valve are designed without bulges.
- the at least one passage opening can be covered at each of an orifice via a valve disk pack, that is, a plurality of axially successive valve disks are provided in the region of the mouth of the at least one passage opening.
- the at least one valve disc is located on a side facing away from the piston body on an intermediate disc, which extends radially over a portion of the at least one valve disc. With the help of this washer, a defined bending of the at least one valve disc can be realized, wherein in the case of a valve disc package, the piston body axially outboard valve disc of the package rests against this washer.

- the respective mouth is released only after reaching a certain pressure in the associated passage openings, which is sufficient to lift the respective valve disc package 8 and 9 from an associated valve seat 17 and 18 respectively.
- the valve disc packs 8 and 9 thus influence the flow of the damping medium via the passage openings and set this against a resistance.
- a defined bending of the individual valve discs of the valve disc packs 8 and 9 is realized by the respective associated intermediate disc 10 and 1 1, which is axially in contact with the outermost valve disc of the respective valve disc package 8 and 9 and until then covered radially with the valve discs , from where the kinking should take place.
