Definitions
- the present invention relates to a compressor system for supplying compressed air to a commercial vehicle with a compressor, a clutch and a
- Auxiliary device wherein the compressor system is drivable via a drive shaft of the drive motor of the commercial vehicle and the compressor is completely decoupled by the clutch from the drive motor.
- Modern commercial vehicles have various subsystems that can be operated with compressed air. This includes, for example, a compressed air powered
- a compressed air supply device is normally provided in the utility vehicle, which comprises a compressor.
- This compressor is mechanically driven by a drive motor of the utility vehicle. Since the need for compressed air within the utility vehicle usually no
- Continuous operation of the compressor may require a clutch between the Drive motor and the compressor may be provided to allow decoupling of compressor and drive. This is desirable because the operation of the compressor consumes energy that can be saved if no compressed air is needed or if the existing compressed air supply the
- Compressed air demand of the consumer over a certain period of time can cover.
- Compressor is switched off.
- the compressor can be disengaged mainly on highways.
- the steering assistance is not absolutely necessary because of the small radii of the curves.
- steering maneuvers for example to
- Electric motor This is in principle feasible, but the electric motor has a large Achieve power of about 50kW, which is why also claimed according to space and weight.
- the document DE 10 2009 023 869 A1 discloses a compressor system and a method for operating such a compressor system for supplying compressed air to a commercial vehicle.
- the commercial vehicle comprises a drive motor and is driven by the drive motor via a drive train.
- Driveline is branched off via a drive a drive train for the compressor system, which comprises a compressor and an auxiliary device, in this case a hydraulic pump.
- the compressor system is driven as a whole by the drive train, wherein via a gear drive a power take-off for driving the hydraulic pump is provided.
- a clutch is arranged, the open or
- a disadvantage of this compressor system is that it takes a relatively large amount of space due to the parallel structure. Furthermore, the gear drive and the drive not only take up additional space but also significantly increase the weight of the entire compressor system.
- a hollow shaft is arranged coaxially to the drive shaft, which can be connected via the clutch to the drive shaft in order to at least indirectly drive at least one respective piston of the compressor movable up and down in a cylinder.
- the drive shaft extends through the hollow shaft and drives the auxiliary device, which may preferably be a hydraulic pump to.
- the auxiliary device is driven independently of a coupling position of the engine via the drive shaft.
- the at least one piston of the compressor is opposite to the clutch on or off.
- the compressor is completely decoupled from the drive motor, whereby energy can be saved.
- the at least one piston via a on a
- This cylindrical, eccentric element is preferably a cam.
- the cylindrical, eccentric element is a part of the hollow shaft.
- the hollow shaft has a single section having a larger radius and an eccentric geometry as compared with the outer radius of the shaft.
- the invention includes the technical teaching that the cylindrical, eccentric element can be plugged onto the hollow shaft. Between the cylindrical,
- eccentric element and the hollow shaft is preferably a press fit.
- a connecting rod connected via a connecting rod with the at least one piston abuts the cylindrical, eccentric element.
- a rotational movement of the hollow shaft is converted via the cylindrical, eccentric element of the adjoining connecting rod and the connecting rod in a translational movement of the at least one piston.
- the compressor has at least two cylinders, each with a piston movable up and down therein, the at least two pistons being driven via cylindrical eccentric elements arranged in series on the outer peripheral surface of the hollow shaft.
- the compressor has at least two cylinders each with a piston movable up and down therein, at least one piston being connected to the outer peripheral surface of the piston
- Hollow shaft arranged cylindrical, eccentric element is driven, and at least one piston is driven directly via the drive shaft.
- the drive shaft at the point where the connecting rod engages preferably a crank.
- the compressor is designed either as a single-stage compressor, as a two-stage compressor or as a multi-stage compressor.
- FIG. 2 shows a schematic representation of a compressor system, comprising a compressor with two pistons, according to a second embodiment
- Fig. 3 is a schematic representation of a compressor system comprising a compressor with two pistons, according to a third embodiment.
- the compressor system of Figure 1 consists essentially of a driven by a drive motor 5 drive shaft 4, which drives an auxiliary device 3. Coaxial with the drive shaft 4, a hollow shaft 6 is arranged, which is connectable via a coupling 2 with the drive shaft 4. As soon as the coupling connecting the drive shaft 4 with the hollow shaft 6 is closed, the hollow shaft 6 rotates at the same speed as the drive shaft 4 after a short start-up phase.
- the hollow shaft 6 drives via an outer peripheral surface of the hollow shaft 6 arranged cylindrical, eccentric element 9a and a connecting rod arranged thereon I Ia a in a cylinder 7a up and down movable piston 8a.
- the piston 8a is connected via a connecting rod 10 with the connecting rod I Ia.
- the compressor system has a compressor 1 with two cylinders 7a, 7b.
- a piston 8a, 8b movable up and down is respectively arranged, wherein the two pistons 8a, 8b are driven via a cylindrical, eccentric elements 9a, 9b arranged in series on the outer circumferential surface of the hollow shaft 6 ,
- the cylindrical, eccentric elements 9a, 9b are offset by 180 ° to each other.
- FIG. 3 shows a further embodiment of the compressor system comprising a compressor 1 with two cylinders 7a, 7b.
- the one piston 8a is driven by a cylindrical eccentric member 9a disposed on the outer peripheral surface of the hollow shaft.
- the other piston 8b is driven directly via the drive shaft 4.
- the drive shaft 4 at the point where the connecting rod 1 lb attacks a crank 12.
- both the auxiliary device 3 and the piston 8b of the compressor 1 is driven at an open coupling position via the drive shaft 4.
- the other piston 8a can be switched on or off via the clutch 2.
