Definitions
- Compressor with hydraulic pump and method for manufacturing a compressor with hydraulic pump
- the invention relates to a system comprising a compressor and a hydraulic pump for use in a commercial vehicle, the compressor comprising a crankshaft for driving the compressor, and wherein the hydraulic pump is drivable by an extension of the crankshaft.
- the invention further relates to a method for producing a system with a compressor and a hydraulic pump for use in a commercial vehicle, wherein the compressor comprises a crankshaft for driving the compressor, the hydraulic pump is driven by a request of the crankshaft and the compressor and the hydraulic pump are integrated in a common housing.
- Modern commercial vehicles have many subsystems that are operated with compressed air. These include, for example, an air-operated service brake or air suspension.
- a compressed air supply device is normally provided in the commercial vehicle, which comprises a compressor.
- This compressor is mechanically driven by the combustion engine of the commercial vehicle.
- the coupling of the compressor This is usually done via a toothing at one end of the crankshaft of the engine.
- the compressor itself has a crankshaft, on the side facing away from the toothing often a hydraulic pump, for example a power steering pump, is arranged.
- a radial play balance bearing for example a Maltese cross, or a multi-tooth bearing, which tolerates a higher torque but tolerates a lesser clearance compared to the Maltese cross.
- the radial play compensation bearing is necessary because the shaft is guided into the compressor on the drive side with a simple slide bearing, whereby a fairly large clearance of up to 0.1 mm is permitted.
- the disadvantage here is in particular the complex connection structure between the compressor and hydraulic pump and the necessary seals between the two separate housings.
- the invention has for its object to simplify the necessary connection structures between the compressor and hydraulic pump.
- the invention is based on the generic system in that the crankshaft is supported by a ball bearing.
- a ball bearing to support the crankshaft of the compressor, the hydraulic pump connected to the compressor can be protected from radial forces.
- the connection between the extension and the crankshaft can therefore be carried out without structurally complicated connecting elements which allow a radial clearance.
- the compressor bearing facing the hydraulic pump can be combined with the compressor facing bearing of the hydraulic pump, since the two separate bearing requiring radial clearance is eliminated.
- crankshaft and the extension are made in one piece.
- a one-piece production of crankshaft and extension represents both the most stable and the structurally simplest way to connect the two parts.
- the compressor and the hydraulic pump are integrated in a common housing.
- the hydraulic pump in the compressor housing possibly necessary seals between the two housing parts can be omitted.
- the hydraulic pump in the housing of the compressor the axial length of the system can be reduced.
- coolant-carrying channels are provided which cool both the compressor and the hydraulic pump.
- additional Connecting elements between the housing of the compressor and the housing of the hydraulic pump which can connect coolant-carrying ducts on the housing of the hydraulic pump to coolant-carrying ducts on the housing of the compressor, which greatly simplifies the production.
- the ball bearing is arranged on the side facing away from the hydraulic pump.
- the arrangement of the ball bearing on the side facing away from the hydraulic pump allows the assembly of the ball bearing after the crankshaft is already mounted in the system with compressor and hydraulic pump.
- the generic method for producing a system with a compressor and a hydraulic pump is further developed in that the shaft is inserted from the side facing away from the hydraulic pump in the common housing.
- the common housing can be made closed on the side of the hydraulic pump, which is why there are no additional Eingriffsm ⁇ goudreen with seals necessary.
- the so-called rear compressor bearing can be mounted in this way together with the shaft.
- the generic method can be further developed, in particular, by arranging a ball bearing on the side of the crankshaft facing away from the hydraulic pump. After inserting the crankshaft into the common housing, no further access to the crankshaft is required for mounting additional bearings. Furthermore, it may be provided that coolant-carrying channels for cooling the compressor and the hydraulic pump are arranged on the common housing. Common coolant-carrying channels allow simultaneous cooling of the compressor and hydraulic pump.
- Figure 1 is a schematic representation of a system according to the invention with compressor and hydraulic pump.
- FIG. 1 shows a schematic representation of a system according to the invention with compressor and hydraulic pump.
- An illustrated system 10 with a compressor 12 and a hydraulic pump 14 is driven by a drive motor 28 of a commercial vehicle 16.
- the compressor 12 includes a cylinder head 36, a piston chamber 32, piston 30, which are coupled via connecting rods 34 with a crankshaft 18 and move up and down in the interior of the piston chamber 32.
- the crankshaft 18 is mounted on the side facing the drive motor 28 by a ball bearing 22 and extended on the side facing away from the drive motor 28 by an extension 20 over the actual area of the compressor 12 addition.
- a bearing 38 is arranged, which is referred to as a rear compressor bearing.
- the bearing 38 combines two previously necessary in this area bearing each other, which were arranged on both sides of a radial play enabling connection between the crankshaft 18 and extension 20.
- the extension 20 of the crankshaft 18 drives a hydraulic pump 14, which is arranged together with the compressor 12 in a housing 24.
- continuous coolant channels 26 are further arranged, via which both the compressor 14 and the hydraulic pump 14 can be cooled.
- crankshaft 18 and the bearing 38 are first introduced into the housing 24 from the side facing away from the hydraulic pump 14, and then the ball bearing 22 is mounted on the side facing away from the hydraulic pump for supporting the crankshaft 18.
- both compressor and hydraulic pump usually have a life that is at least identical to the vehicle life.
