- the wheel bearing assembly comprises a hollow body unit, a fixing unit and a stator unit, wherein the hollow body unit has a maximum extent along an axial direction, a pressure chamber extending substantially along the axial direction and an end portion, wherein the fixing unit is fixed to the end portion, wherein at the fixing unit Statorü is fixed and wherein the stator unit has fastening and sealing means by means of which a rotor unit airtight and rotatable relative to the stator to the wheel bearing assembly can be added.
- the hollow body unit is preferably a preferably rigid or steerable axle of a commercial vehicle that reaches its maximum extension along an axial direction A.
- the hollow body unit is designed as a hollow body, or tubular body, with inner and outer diameters that are variable along the axial direction.
- the hollow body unit At a first end in the axial direction, the hollow body unit has an end portion.
- a fixing unit is fixed to the hollow body unit, wherein corresponding means for fixing the two units to one another are provided on the hollow body unit and on the fixing unit.
- the hollow body unit has a pressure chamber, which preferably serves to guide a fluid, particularly preferably air, within the hollow body unit. It is advantageous if the pressure chamber is sealed by appropriate sealing means so that it can hold pressures of up to 15 bar, but at least 6 bar.
- the stator unit is fixed to the fixing unit and has fastening and sealing means for fastening or sealing a rotor unit attached to the stator unit.
- the stator unit is characterized in that it adjoins the pressure chamber with a first end and can be attached to a rotor unit with a second end, opposite the first end.
- the stator unit is fixed relative to the fixing unit and the hollow body unit, ie it can not rotate or shift relative to the hollow body unit or fixing unit.
- the rotor unit to be mounted on the stator unit is rotatably supported relative to the hollow body unit, fixing unit and stator unit.
- the rotor unit is fixed to further rotating units of the wheel bearing assembly.
- the stator unit has sealing means, which preferably also sufficiently seal when the two are to be sealed against each other Move parts relative to each other.
- sealing means which preferably also sufficiently seal when the two are to be sealed against each other Move parts relative to each other.
- the stator unit preferably has a recess or a through bore extending along the axial direction, through which compressed air can pass from the pressure chamber into the stator unit and from there into the rotor unit. In this way, compressed air can pass from the stationary hollow body unit or from the stationary pressure chamber via the stator unit into the rotor unit and thus into the rotating part of the wheel bearing arrangement.
- the tire pressure in the tire can preferably be determined directly at any time, since the pressure in the tire, with unhindered flow of the components through which it flows, is equal to the pressure in front of the monitoring unit.
- specific target values for the tire pressure can be stored in the monitoring unit, which are compared with the currently existing tire inflation pressure and appropriate measures are initiated.
- the monitoring unit has a
- the hollow body unit has a storage area adjacent to the end section, wherein a bearing arrangement is mounted on the hollow body unit in the storage area and can be clamped by the fixing unit against displacement relative to the hollow body unit.
- the hollow body unit thus preferably fulfills a second object, namely to receive a bearing arrangement and to clamp it.
- the Lageran- order serves to secure a rotor or a rotating assembly against displacement relative to the hollow body unit and rotatably support relative to the hollow body unit.
- the rotating component to be supported rotatably about the hollow body unit may, for example, be a wheel hub with a brake disc or brake be drum.
- the hollow body unit has a bearing area, which is preferably located on the outside, that is, at one end of the hollow body unit adjacent to the end portion.
- the storage area moreover preferably has a projection pointing inward in the axial direction towards the center of the hollow body unit, to which the storage arrangement can preferably be deposited.
- the bearing assembly is secured in this way against displacement or displacement along the axial direction towards the center of the hollow body unit.
- the fixing element preferably engages in threads provided for this purpose or similar fastening means, brings a force in the axial direction towards the center of the hollow body unit and thus secures the bearing arrangement against displacement outward along the axial direction.
- the bearing arrangement is preferably a rolling bearing, for example a tapered roller bearing, ball bearing or cylindrical roller bearing, which can preferably transmit forces in the axial direction and transversely in the radial direction and in this way fixes the rotating component of the wheel bearing arrangement both in the radial direction and in the axial direction.
- the fixing unit is preferably applied to the stationary or relative to the hollow body unit non-rotatably mounted inner ring of a rolling bearing and exerts a force on this. This function to be performed by the fixing unit is preferably comparable to the function of a wheel nut or axle bolt which secures one or a plurality of bearings directly or by means of one or a plurality of spacers against displacement in the axial direction.
- the pressure chamber is a recess in the hollow body unit, wherein the pressure space is delimited at a first end by a supply nozzle and at a second end by a fixing unit and the stator unit.
- the recess according to the invention in the hollow body unit is equal to the pressure chamber.
- sealing elements which are arranged both on the compressed air supply, ie in the region of the supply nozzle, and also on the compressed air removal, ie in the range of fixing unit or stator unit.
- These sealing elements are preferably static seals, ie seals between two parts that are not moving relative to each other. It is preferable to resort to conventional sealing elements such as O-rings or profile sealing rings.
- a recess in the hollow body unit is introduced and provided with a thread in the region of the supply nozzle, wherein the supply nozzle, on which an external thread is provided, can be screwed into the recess.
- a compressed air line, via which the compressed air passes into the hollow body unit, can preferably be attached to the supply nozzle.
- an end portion sealing element is provided on the contact surface between the end portion and the fixing unit.
- This sealing element between the end portion of the hollow body unit and the fixing unit, compressed air is prevented from escaping through gaps formed between the end portion and the fixing unit.
- This seal is preferably required when the hollow body unit or the recess in the hollow body unit is used as a pressure chamber. In this case, on the one hand, it must be ensured that the compressed air does not escape in an uncontrolled manner over the contact surface between the end section and the fixing unit, and furthermore that any adjacent assemblies, such as the bearing arrangement, are not exposed to compressed air and possibly damage in them Subassemblies are caused.
- the second fastening region is designed as a disk, which is pressed against the hollow body unit by the first fastening region, wherein a seal can be provided on the contact surface between the second fastening region and the hollow body unit, which prevents the escape of compressed air from the pressure chamber ,
- the concentric alignment of the stator unit relative to the axial direction is particularly important for the reason that the stator unit is connected to a rotating component of the rotor unit, wherein the axial direction is the axis of rotation. Eccentric bearing of the stator unit would result in a translatory movement of the rotor unit and resulting damage.
- the second attachment region protrudes into the recess of the hollow body unit.
- the second attachment portion has an inner portion which extends substantially in the axial direction and thus protrudes into the recess on the hollow body unit. This can be particularly preferred when the space at the end of the hollow body unit is limited and must be avoided outwardly projecting or protruding from the hollow body unit parts.
- a venting recess is provided on the fixing unit.
- This vent recess can relieve the system or the pressure chamber especially at too high pressure.
- the venting recess is mounted so that compressed air, which could get past the seal between the end portion and fixing unit, does not get into the storage area, but is discharged through the vent hole in the environment.
- the vent recess thus represents a security element, which ensures that the safe Operation of the wheel bearing assembly is not affected by escaping compressed air, which enters the storage area.
- FIG. 2 shows a further sectional view of a preferred embodiment of the wheel bearing arrangement according to the invention
- Fig. 3 is a further sectional view of a preferred embodiment of
- This recess preferably has a thread, so that the stator unit 5 can be screwed into the second fastening region 32 of the fixing unit 3 by means of a corresponding thread.
- the stator unit 5 in turn has on its inner side suitable seals and projections, which make it possible to attach a - not shown in the figure - rotor unit to the stator 5 and to connect airtight with this.
- the compressed air can pass from the pressure chamber 15 into the stator unit 5 and over the rotor unit as far as further rotating parts of the wheel bearing arrangement via the rotor unit. So that the air in the pressure chamber 15 can not escape other than via the stator and the rotor unit 5, a seal 9 is provided, which is located between the hollow body unit 1 and fixing unit 3.
- a recess with an internal thread is provided on the hollow body unit 1, into which a male thread attached to the supply pipe 14 can engage and in this way defines the supply pipe to the hollow body unit.
- the supply nozzle 14 has suitable geometries, which preferably serve to define a pressure line at the supply nozzle 14 and to guide compressed air into the supply nozzle 14 via this pressure line, which in turn feeds the compressed air into the pressure chamber 15.
- FIG. 2 shows a preferred embodiment of the fixing unit 3, which is attached to the hollow body unit 1.
- FIG 4 shows another preferred embodiment of the fixing unit 3, wherein the fixing unit 3 is made in one piece. Furthermore, the fixing unit 3 has an external thread, which is preferably screwed into a designated internal thread on the hollow body unit 1. In a recess on the fixing unit 3, which is aligned concentrically to the axial direction A, the stator 5 can be screwed. Preferably, a sealing element 9 is provided on the contact surface between the hollow body unit 1 and fixing unit 3.
