Definitions
- the invention relates to a roller bearing for mounting a steering shaft, consisting of two bearing rings with roller bodies arranged between them, the inner ring being received by a tolerance ring made of an elastically resilient polymeric material and means for transmitting the electrical current from the steering shaft to a steering tube receiving the roller bearing are.
- the invention relates to a steering bearing, the outer ring of which is received by a tolerance ring made of an elastically resilient polymeric material.
- Rolling bearings of this type are used for mounting steering shafts in steering columns of motor vehicles.
- the bearing is an angular contact ball bearing, which is used together with another angular contact ball bearing and forms a bearing arrangement with this additional angular contact ball bearing and different preloading and supporting elements.
- Such a bearing arrangement is previously described in DE 40 13 655 C2.
- a generic angular contact ball bearing as is often used for the bearing of steering shafts, is previously known from DE 38 08 556 A1.
- the inner ring is received by a Toieranzring made of plastic, which engages behind the inner and outer ring with a radial projection.
- a spring element in the form of a spring ring is arranged, which is held in the tolerance ring by a locking disk, which is also secured in the tolerance ring by a radially inward projection.
- a bearing is used as an upper steering bearing in a steering column, means for transmitting the electrical current from the steering shaft via the roller bearing to the receiving steering tube must be present. This is necessary to activate the signal horn or to deploy the airbag.
- the conductive connection between the steering shaft and steering tube can, for example, be such that a clock spring connects the steering shaft and steering tube in a conductive manner.
- a conductive intermediate ring is arranged in the upper steering bearing, which creates a current-conducting connection between the steering shaft and the inner bearing ring. In this case, the power is transmitted via the steering shaft, conductive intermediate ring, inner race, rolling element, outer race to the steering tube.
- an additional part namely the clock spring or the intermediate ring must be manufactured and handled. This makes the assembly process more expensive and increases the price of the steering bearing.
- the object of the invention is therefore to develop a steering bearing, the manufacture and assembly of which is simplified.
- this object is achieved according to the characterizing part of claim 1 in that the tolerance ring is made of an electrically conductive polymeric material.
- the conductive connection between the steering shaft and steering tube is thus taken over by an inherent component of the steering bearing itself.
- immanent is to be understood literally as “inherent, containing in the matter concerned”. It is obvious that this simplifies the assembly of a steering bearing, since an additional component that takes over the power line does not have to be manufactured and does not have to be handled.
- the electrical properties of plastics are usually such that they are used as insulating materials. Appropriate measures, however, can be used to increase the electrical conductivity to such an extent that they behave like metals, ie conduct the electrical current.
- the conductivity of the polymeric material is realized by adding carbon, steel fibers or soot particles. This has the advantage that the conductivity of the polymer plastic is already present during its manufacturing process, so that post-treatment of the finished plastic part is not necessary.
- the conductivity of the polymeric material can also be produced by a metallic coating, wherein according to claim 4 this metallic coating should be applied galvanically, chemically or by PVD processes.
- Galvanic process engineering basically allows components of almost any shape to be provided with dense, non-porous and firmly adhering metal coatings.
- the deposition is carried out in a known manner from aqueous solutions which contain the metal to be deposited in the form of ions. By applying voltage, the metal ions are transported to the component surfaces, where they are reduced and adhered to the surface.
- the chemical or electroless metallization is carried out in a known manner in such a way that metal ions are precipitated from a salt solution by reducing agents.
- the metallic precipitate that forms is deposited on the component.
- the metal layers deposited during direct currentless metallization are generally very thin, with layer thicknesses in the range from 1 to 5 ⁇ m being common.
- Metal layers deposited in such a currentless manner can then be galvanically reinforced if required.
- PVD processes to be layers which are produced on the principle of "physical vapor deposition", ie they are formed by the deposition of atoms or molecules from the gas phase.
- the layer thickness range of these layers can range from a few tenths of a ⁇ m to a few millimeters.
- the PVD processes include vacuum evaporation (sputtering), sputtering (sputtering layers) and ion plating.
- vacuum evaporation metal is evaporated in a known manner in a vacuum chamber and is deposited on the surface of the component.
- the advantage of this process lies in the high separation speed. In general, only thin layers down to approx. 1 ⁇ m are deposited in these processes, because tensions can occur in thicker coatings due to the relatively high process temperature, which can lead to crack formation and delamination.
- the coating material is knocked out of a target by noble gases generated in a glow discharge plasma, atomized and deposited on the component mounted near the target.
- the metallic coating should be a copper or a silver layer. Both metals are particularly advantageous because, on the one hand, they have a very high electrical conductivity and, on the other hand, they can also be deposited relatively easily onto a plastic component using the methods described above.
- the tolerance ring is made of a conductive polyamide.
- Polyamides are known to the person skilled in the art because of their outstanding mechanical properties known. In particular, they have good dimensional stability under heat and are very resistant to fuels and lubricants.
- the rolling bearing is filled with an electrically conductive grease.
- Such greases usually contain a 20% copper content and ensure that the current transfer from the inner ring to the rolling element and the outer ring is improved.
- roller bearing is designed as an angular contact ball bearing
- the tolerance ring has resilient retaining tongues over part of its axial length due to recesses evenly spaced apart in the circumferential direction, which engage behind the inner ring with a radial projection
- a clamping element at the other end of the tolerance ring is arranged for the axial preloading of the bearing and the bearing balls are guided in a cage which at one end has a radially outwardly facing first projection which engages behind the outer bearing ring and at the other end a radially inwardly facing second projection which engages behind the inner bearing ring owns.
- the tensioning element should be designed as a corrugated spring which engages with corresponding recesses of the tolerance ring with uniformly spaced axial projections. In this way, a captive bearing assembly is formed with simple means, which can be handled very well.
- a second special embodiment of a steering bearing emerges from claim 10. Thereafter, the bearing outer ring should be formed in two parts, the tolerance ring form a component integrally connected with a spring and have radially elastic projections and axially elastic ribs on the opposite side of a radially inwardly projecting flange of the bearing inner ring.
- the roller bearing can also be designed with a tolerance ring made of an electrically conductive polymeric material which, in reverse of the procedure, receives the bearing outer ring of a roller bearing with its inner receiving bore.
- the bearing outer ring is designed as a thin-walled, slotted sleeve which surrounds the bearing needles with pretension and which is in turn surrounded by the tolerance ring with pretension.
- Figure 1 shows a longitudinal section through a steering column bearing
- Fig. 2, 3, 4 shows a longitudinal section through differently designed steering bearings.
- the steering column 1 shown in Figure 1 consists of the steering shaft 2, which is rotatably mounted at its upper and at its lower end via two spaced needle bearings 4 in the stationary steering tube 3.
- the needle bearings 4 shown enlarged in FIG. 2 consist of the thin-walled sleeve 5, which has the continuous slot 6 at one point on its circumference.
- the inner circumferential surface of the sleeve 5 forms the outer raceway (not designated) for the bearing needles 8 guided in the cage 7.
- the second raceway of the bearing needles 8 is formed by the circumferential surface of the steering shaft 2.
- the slotted sleeve 5 is surrounded by the elastic tolerance ring 9 ben, so that the bearing needles 8 are held by the tolerance ring 9 or the slotted sleeve 5 under tension, ie the needle bearing 4 is set without play.
- the elastic tolerance ring 9 is provided on its outer lateral surface with knobs 10 and 11 which are arranged next to one another and which have a different radial extent. If the tolerance ring 9 is now made from an electrically conductive polymeric material in the manner according to the invention, the current flow through the needle bearing 4 can start from the metallic steering shaft 2 via the metallic bearing needles 8 of the sleeve 5 and the conductive tolerance ring 9 to the metallic steering tube 3.
- the angular contact ball bearing 12 shown in FIG. 3 consists of two non-cutting bearing rings 13 and 14, between which bearing balls 15 which are guided in the cage 16 roll on associated raceways.
- the bearing rings 13, 14 are made without cutting from St4 or 16MnCr5 steel, case-hardened and tempered.
- the cage 16 engages behind the bearing outer ring 13 on the left side with a radially outwardly directed first projection 17 and engages behind the bearing inner ring 14 on the other side with the radially inwardly directed second projection 18.
- the inner ring surface of the bearing inner ring 14 sits on the tolerance ring 19, which in turn is made in accordance with the invention from an electrically conductive polymeric material.
- This tolerance ring 19 is subdivided into holding tongues 21 by recesses 20 which are evenly spaced apart around its circumference and which engage behind the bearing inner ring 14 with the radially outward projection 22. In this way, a captive unit is formed by the tolerance ring 19 and the bearing cage 16.
- the tolerance ring 19 is equipped with a corrugated spring 23 which has axially directed projections 24 which engage in associated recesses 25 of the tolerance ring 19.
- the electrical current is again conducted via the steering shaft 2, not shown, the conductive higen tolerance ring 19, the bearing inner ring 14, the bearing balls 15 and the bearing outer ring 13 to the steering tube 3, also not shown.
- the ball bearing 26 consists of the bearing outer ring 27, the two partial rings 28, 29 of which are received by the sleeve 30 with ribs folded inwards.
- the other raceway for the bearing balls 33 is formed by the bearing inner ring 31, which has a radially inwardly projecting flange 32 on the left side.
- the tolerance ring 34 is in turn made of a conductive polymeric material and is arranged within the receiving bore of the bearing inner ring 31.
- a spring 35 which consists of the same polymeric material as the tolerance ring 34 and is made in one piece with it, borders on the right end face of the tolerance ring 34.
- a plurality of ribs 36 arranged one behind the other in the circumferential direction serve as spring elements.
- the tolerance ring 34 has a plurality of radially elastic projections 38 which protrude into the area of the bore of the tolerance ring 34. These projections 38 can snap into recesses 39 in the steering shaft 2 and are supported within the recesses 39 on supporting surfaces 40, the supporting surfaces 40 preferably being located in planes perpendicular to the steering shaft axis.
- the current transfer takes place in the manner already described from the steering shaft 2 via the conductive tolerance ring 34, via the bearing inner ring 31, the bearing balls 33 and the bearing outer ring 27 to the steering tube 3.
