- the at least one drive shaft bearing and the at least one connecting rod bearing are arranged such that the at least one drive shaft bearing is located at least partially within the at least one connecting rod bearing in the radial direction.
- the case that the drive shaft bearing is completely in the connecting rod bearing interior is referred to as complete coverage.
- the synergetic aim of the concept of the invention is to prevent negative, in particular caused by bending mechanical effects such as vibrations, structure-borne noise and airborne sound development both by the axially overlapping bearing arrangement and by the improved introduction of the connecting rod forces in the housing as possible.
- This is achieved in particular by the axial arrangement of the first bearing or A-bearing within the connecting rod bearing and the frame-fixed attachment of the inner ring of the A-bearing on the frame-fixed axle journal.
- tilting moments are reduced or avoided on the drive shaft bearings, in particular on a first bearing or A-bearing and on the drive shaft acting axial forces.
- low-noise and low-vibration operation is of great importance, since here, in contrast to applications in the truck sector, the acoustic requirements are higher or more sensitive.
- the concept preferably provides the basis for a functioning in an improved manner, in particular vibration and low noise compressor assembly. Furthermore, a reduction of forces and / or moments, and in particular a reduction of the dynamic loads and vibrations associated with the forces and / or moments, lead to a gentler mode of operation which has a positive effect on the efficiency and longevity of the compressor arrangement.
- these loads include, in particular, tilting moments acting on the connecting rod bearing, which occur in a conventional drive shaft bearing by shaft bending.
- the reduction or avoidance of such tilting moments by a storage according to the concept of the invention leads to a better durability of the connecting rod;
- the connecting rod can thereby be designed smaller and thus lighter, in particular in a constructive optimization.
- the drive shaft is mounted in the connecting rod-side drive shaft bearing, which is arranged on a connecting rod end of the drive shaft in a bearing plane, as the first bearing on a first bearing receiving section arranged coaxially with the axis of rotation.
- the further development is based on the consideration that a distance in the axial direction between the bearing plane of the first bearing, or A-bearing and connecting rod plane, leads to a bending moment, which in particular in a Forming the drive shaft results.
- a deformation can lead to possibly unfavorable dynamic load conditions and noise and vibration development in the case of a rotating drive shaft.
- noise and vibration developments can be further enhanced by possibly over the operating time increasing bearing clearance.
- Deformations of the drive shaft are due in particular to connecting rod forces, which arise in a compression of the air by the movement of the compressor piston in the cylinder and are passed through the connecting rod bearing and / or the first bearing or A-bearing in the drive shaft.
- the bending moment is proportional to the Pleuel practicen and the distance in the axial direction between the bearing plane and the connecting rod level.
- the development has recognized that with a reduction of the distance in the axial direction between the bearing plane of the first bearing or A-bearing and the connecting rod plane of the connecting rod acting on the drive shaft bending moment is reduced.
- a reduction can be achieved in particular if the first bearing or A-bearing is arranged in the radial direction within the connecting rod bearing.
- the distance in the axial direction between the bearing plane of the first bearing or A-bearing and the connecting rod level of the connecting rod bearing caused by a connecting rod, acting on the drive shaft bending moment is completely avoided.
- the drive shaft is mounted in the arranged at a connecting rod distal end of the drive shaft connecting rod drive shaft bearings as a second bearing on a coaxial with the axis of rotation at the end of the connecting rod remote second bearing-receiving portion.
- the housing may include and house the compressor assembly and / or the drive and / or other components, and particularly advantageously modular in particular, in each case for compressor assembly and drive individually, but composable, be formed.
- the compressor assembly of the first bearing receiving portion for receiving the first bearing is formed as a cylindrical cavity, and / or the first bearing is further mounted on a frame fixed to the housing and mounted substantially coaxially to the axis of rotation journals, wherein the first bearing in the cylindrical cavity between the first bearing receiving portion and the journal sits.
- the first bearing firmly seated on the axle journal and stuck in the first bearing-receiving portion and the axle journal and the first bearing-receiving portion rotatably connects relative to each other.
- the bearing outer ring of the first bearing is fixed to the bearing-receiving section of Drive shaft connected. In this way, a rotational relative movement between the frame-fixed axle journal and the drive shaft is made possible about the axis of rotation.
- the compressor has a plurality of, in particular a first connecting rod and a second connecting rod. Specifically, this may involve compressing gas, especially air, into two or more compression chambers.
- a two-stage compressor is realized by the arrangement of two cylinders, the cylinders each having a compressor piston and a connecting rod. These are driven in particular by a drive shaft and are preferably arranged such that the overall system is in a practically balanced state.
- a two-stage compressor leads in particular to the advantages of higher achievable efficiencies and compression pressures.
- first connecting rod and the second connecting rod are arranged such that the first connecting rod in a first bearing spacing and the second connecting rod are arranged in a second bearing distance in the axial direction, ie in the direction of the axis of rotation, to the bearing plane.
- first and the second bearing spacing can be selected depending on the design requirement such that in particular deformations of the drive shaft and loads on the connecting rod and bearing can be minimized as possible.
- bending moments acting on the drive shaft can be minimized by reducing the bearing distance to the connecting rod receiving the larger forces.
- the setting of the bearing spacing can be used advantageously to produce a wave bending, in particular to compensate for a deformation of the axle journal.
- This is illustrated by way of example in the drawing in FIG. 3 and further explained in connection with FIG. 3 by way of example within the framework of a preferred embodiment.
- the first connecting rod and the second connecting rod are arranged such that the bearing plane in the axial direction centrally between a first connecting rod plane (already here for clarity: in the drawing with P1) and a second connecting rod level (already here for clarification: indicated in the drawing by P2).
- this means that the first and the second connecting rod level are arranged in an equal axial distance in terms of magnitude, but in the opposite direction to the bearing plane.
- the compressor has a first connecting rod, which is arranged in the bearing plane of the first bearing, the bearing distance between the connecting rod level and bearing level is practically equal to zero.

This is illustrated by way of example in the drawing in FIG. 3 and further explained in connection with FIG. 3 by way of example within the framework of a preferred embodiment.
- the first connecting rod and the compressor piston are rigidly connected to each other, in particular the compressor is designed as a wobble piston compressor.
- the compressor is designed as a single-stage compressor. Specifically, this means that the gas, in particular the air, is compressed in a compression chamber.
- This compression chamber is formed by the interior of the cylinder and the conrod-side opposite side of the compressor piston.
- the compressor is designed as a multi-stage compressor, in particular two-stage compressor.
- Such a multi-stage compressor can be realized by the arrangement of several, in particular two, pistons, the pistons each having a compressor piston and a connecting rod. These are driven in particular by a drive shaft and are preferably arranged such that the overall system is in a practically balanced state.
- the gas can be compressed, for example, in two compression chambers, which are each formed by a cylinder and a double-sided pressurizable compressor piston.
- the connecting rod opposite side of the compressor piston in this case forms, together with the lying on this side of the compressor piston interior of the cylinder, the first compression chamber.
- the side facing the connecting rod further forms, together with the interior of the cylinder located on that side of the compressor piston, the second compression chamber.
- the connecting rod bearing is formed as a rolling bearing, in particular a ball bearing, needle roller bearings, cylindrical roller bearings, roller bearings or the like rolling bearing.
- Needle and cylindrical roller bearings and rolling bearings with cylindrical rolling elements generally have a high radial load capacity due to the line contact with the running surface.
- Ball bearings have a relatively high axial and radial load capacity due to the osculation in the rolling contacts.
- Barrel bearings also allow, due to the crowned design of the rolling elements and a hollow spherical outer ring raceway, a certain oscillating movement between the inner and outer ring.
- the first bearing and / or the second bearing is formed as a sliding bearing. Specifically, this can be achieved by a lubricated or lubrication-free slide bearing. This leads advantageously to a low-maintenance, particularly preferably maintenance-free, interpretation of the rotatable connection, since they - apart from the Relativbewe- between shaft and bearing - no moving parts, in particular no rolling elements, has.
- the first bearing and / or the second bearing is fixed non-positively, in particular by a tolerance ring.
- the tolerance ring may be formed by a metal spring ring, or a ring made of rubber or plastic with a suitable cross section, or another suitable, compressible connecting element.
- the first bearing or A-bearing and / or the second bearing or B-bearing alternatively and / or additionally also in other ways, for example by a form-fitting locking ring arranged in the axial direction or by frictional or thermal Shrink, be fixed.
- a tolerance ring may relate both to the inside of the inner ring and on the outside of the outer ring of the respective bearing. Consequently, for example, a tolerance ring arranged between the cavity and the outer ring of the first bearing would be possible for the first bearing as well as between a tolerance ring arranged between the axle journal and the inner ring.
- the invention leads to the solution of the problem also to a compressed air supply system for operating a pneumatic system.
- This compressed air supply system comprises: an aforementioned compressor assembly, an air dryer and a valve assembly.
- the invention for solving the problem also leads to a vehicle with a compressed air supply system and a pneumatic system, wherein the compressed air supply system has a compressor arrangement according to the concept of the invention.
- a compressor arrangement according to the concept of the invention is advantageous in particular in passenger cars, since high acoustic requirements prevail in the area of the passenger cars and a low-noise and low-vibration operation of the compressor arrangement is or is of great importance.

- the first compressor piston 150 is near top dead center, i. H. at the upper end of the stroke H, shown. Due to the fact that it is a wobble piston compressor in the embodiment shown here, that is, the first connecting rod 140 and the first compressor piston 150 are rigidly connected, the oscillating movement is predominantly, but not completely translational. Therefore, the first connecting rod 140 and the first compressor piston 150 in the up and down movement perform a kinematics corresponding, tumbling motion.

- connecting rod receiving portion 320 is integrally connected to the drive shaft 220;
- connecting rod receiving portion 320 and drive shaft 220 are designed in two pieces and are joined together via a corresponding positive, non-positive or cohesive connection.

- the resulting, specifically induced deformation can, analogous to the bearing arrangement described in Fig. 3B, be used to compensate for the deformation of the journal 450.
- a bearing arrangement shown in FIG. 3D can furthermore be used selectively to take account of and compensate for this circumstance.
- the connecting rod force FP2 acting on the second connecting rod bearing 161 is greater than the connecting rod force FP1 acting on the first connecting rod bearing 1 60. Consequently, the axial position of the A-bearing 360 is shifted in the direction of the more heavily loaded connecting rod bearing, in this case the connecting rod bearing 161, so that the second bearing clearance LA2 is smaller than the first bearing clearance LA1.
- Critical deformation in this context refers to a deformation which leads directly or indirectly to one or more of the disadvantages mentioned at the outset, in particular with regard to noise and vibration development and wear behavior.
- Fig. 4 shows a schematic representation of a deflection of a drive shaft 220 and a stub axle 450. In this simplified view, the deformations are exaggerated.
- a connecting rod force FP which acts on the connecting rod bearing 1 60, is transmitted to the drive shaft 220 and thus to the A bearing 360.
- the drive shaft 220 is deformed such that the B-bearing 362 as low as possible forces, in particular lateral forces and Tipping moments, act.
- the pin deflection ZA is thus partially or completely compensated.
- FIG. 5 shows a greatly simplified, schematic overview of a compressed air supply system 500 with a compressor arrangement 1000 according to the concept of the invention for supplying a pneumatic system 600.
- the compressed air supply system 500 has an air intake 0 for sucking in fresh air, which continues to carry fluid with an inlet of the compressor 100 , in particular gas-conducting, is connected.
- the compressor 100 is driven as part of the compressor assembly 1000 by a drive 200 via a drive shaft 220.
- the compressed fresh air is further provided via a compressed air source 1, which is followed by a branch 510.
- a vent valve 520 a vent 3 is connected.
- an air dryer 520 is connected to the branch 510, which continues to lead to a compressed air connection 2.
- the pneumatic system 600 can be, for example, an air spring system or a further pneumatic system, in particular a vehicle. Furthermore, individual valves, throttles and the like adjusting means and individual components, in particular the pneumatic system, not shown in this illustration for reasons of clarity and simplicity.
- Fig. 6 shows a schematic representation of a vehicle 800 - present in the form of a car - with a compressed air supply system 500 and a pneumatic system 600.
- a low-noise and low-vibration operation is of great importance, since here, in contrast to Applications in the truck sector, the acoustic requirements are higher or more sensitive. This, therefore, without limiting the applicability for trucks or other commercial vehicles, exemplified car 800 has four wheels 801, 802, 803 and 804, of which the two respective front wheels are shown here due to the sectional view.
- the pneumatic system 600 has four air springs 601, 602, 603 and 604, of which the two respective front air springs are shown here analogous to the wheels due to the sectional view.
- the air springs 601, 602, 603 and 604, which are respectively associated with the wheels 801, 802, 803 and 804, are supplied as part of the pneumatic system 600 by the compressed air supply system 500 with compressed air.
- the compressed air supply system 500 is fluidly connected via the gallery 570 with the components of the pneumatic system 600, in this case the air springs 601, 602, 603 and 604 shown here.
- the compressed air supply system 500 is shown greatly simplified in this illustration, so that only the compressed air reservoir 560 and the compressor 100 according to the concept of the invention is visible.
- the compressor 100 according to the concept of the invention can additionally or alternatively be used independently of the compressed air supply system in a modification not shown here.
- the concept preferably provides the basis for a functioning in an improved manner, in particular vibration and low noise compressor assembly. Furthermore, a reduction of forces and / or moments, and in particular a reduction of the dynamic loads and vibrations associated with the forces and / or moments, lead to a gentler mode of operation which has a positive effect on the efficiency and longevity of the compressor arrangement.
