Definitions
- the invention relates to a roller bearing, in particular an angular contact ball bearing, for mounting a steering shaft of a motor vehicle, comprising a bearing inner ring and a bearing outer ring, between which bearing balls roll on associated raceways, the bearing inner ring being 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 various preloading and supporting elements.
- Such a bearing arrangement is previously described in DE 40 13 655 C2.
- 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 the steering tube can be made, for example, in such a way that a coil spring connects the steering shaft and the 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 bearing 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 such a steering bearing.
- Such a steering bearing is previously described in DE 19952 119 A1.
- the object of the invention is therefore to develop a steering bearing, the manufacture and assembly of which is simplified and which has good electrical conductivity.
- this task is performed according to the characterizing part of Claim 1 in connection with its preamble solved in that the bearing inner ring merges into an axially extending area following its raceway area, this axially extending area being provided with at least one circumferential point with two spaced-apart incisions, so that at least one elastic projection is formed , which is directed radially inward and makes a conductive contact with the steering shaft.
- the conductive connection between the steering shaft and the steering tube is taken over by the inner ring of the bearing itself, so that on the one hand an additional component that takes over the power line does not have to be manufactured and handled.
- This unnecessary component reduces the overall cost of the warehouse.
- the tolerance ring is provided with an exemption in the region of this elastic projection.
- 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 bearing inner ring with a radial projection, a tensioning element is arranged at the other end of the tolerance ring for the axial preloading of the bearing and the bearing balls are guided in a cage on one End has a radially outwardly facing first projection engaging behind the bearing outer ring and at the other end a radially inwardly facing second projection engaging behind the bearing inner ring.
- the tensioning element is to be a corrugated spring which engages with corresponding recesses of the tolerance ring with axial projections which are evenly spaced apart in the circumferential direction.
- the bearing inner ring and the bearing outer ring are produced by a non-cutting shaping process and are subjected to a hardening process.
- the bearing outer ring merges into an axially extending region following its raceway region, this axially extending region being provided with at least one circumferential location with two spaced-apart incisions, so that at least one elastic projection is formed which extends radially is directed outside and makes a conductive contact with the steering tube.
- 1 and 2 show a longitudinal section through a steering bearing according to the invention without or with a steering shaft
- 3 shows a longitudinal section through the bearing inner ring
- Figure 4 is a plan view of the bearing inner ring in the region of the elastic projection.
- the angular contact ball bearing 1 shown in FIGS. 1 and 2 consists of the two non-cutting bearing rings 2 and 3, between which bearing balls 5 run on associated raceways in the cage 4.
- the bearing rings 2, 3 are made of St4 or 16MnCr5 steel, case-hardened and tempered.
- the cage 4 engages behind the bearing outer ring 3 on the left-hand side with the radially outwardly directed projection 6 and engages behind the bearing inner ring 2 on the right-hand side with the radially inwardly directed second projection 7.
- the bearing inner ring 2 is seated on the tolerance ring 8 with its inner circumferential surface polymeric material and is subdivided into holding tongues 10 by spacings 9 which are evenly spaced apart around its circumference and which engage behind the bearing inner ring 2 with the radially outwardly directed projection 11.
- a captive unit is formed by the tolerance ring 8 and the bearing cage 4.
- the tolerance ring 8 is equipped with the corrugated spring 12, which has axially directed projections 13 which engage in associated recesses 14 in the tolerance ring 8.
- the bearing inner ring 2 has the raceway area 2.1, which merges into the axially extending area 2.2. At least one circumferential point, preferably three circumferential points, the axially extending region 2.2 is provided with two notches 2.3 spaced apart in the circumferential direction, so that an elastic projection 2.4 is formed.
- This elastic projection 2.4 is oriented radially inwards in the direction of the bearing axis 16 and, as FIG. 2 shows, bears against the steering shaft 15. The management of the electrical see current takes place via the steering shaft 15, the bearing inner ring 2, the bearing balls 5, the bearing outer ring 3 up to a steering tube, not shown.
