Definitions

  • the invention relates to a drive shaft with an attached carrier for a pulley according to the preamble of claim 1.
  • Drive shafts of the type discussed here are known. Decisive for safe operation is the attachment of the driver for a pulley to the drive shaft and its axial securing. Due to vibrations that are based inter alia on the torque input to the pulley and the mounted on the drive shaft consumers, in particular a pump of a motor vehicle, often loosens the connection between the drive shaft and driver. This creates an axial clearance between the drive shaft and driver, which ultimately leads to damage or failure of the drive shaft-driver connection due to the vibrations.
  • the object of the invention is therefore to provide a secure connection between the drive shaft and a driver for a pulley, which ensures safe operation even with strong vibrations.
  • a drive shaft which has the features mentioned in claim 1.
  • a driver for a pulley is attached, via which a torque is introduced into the drive shaft.
  • This can be coupled, for example, with a pump, in particular a compressor, of a motor vehicle.
  • the drive shaft is characterized in that the driver is fastened by means of a clamping disc on the drive shaft such that it is flush with a shoulder the drive shaft is applied.
  • the drive shaft thus passes through the driver with a stub shaft on which a clamping disc is pushed and pressed from its free end.
  • the driver attaches to a shoulder of the drive shaft, with at most a minimal, axial clearance between the driver and the shoulder is given.
  • vibrations can cause virtually no axial movement between the driver for the pulley and the drive shaft, so that no axial shocks on the attachment of the driver to the drive shaft Act. During operation of the drive shaft loads on the attachment of the driver are thus reduced to a minimum.
  • a preferred drive shaft is characterized in that a fastening washer is arranged between the driver and the clamping disk. Their material can be adapted to the direct coupling between the drive shaft and driver so that it results in a particularly secure connection.
  • Another preferred drive shaft is characterized in that on the driver elastic damping elements are provided, the torque fluctuations that can occur in particular by acting on the pulley forces, but also by the attached to the drive shaft consumer, to a minimum. This leads to a further relief of the connection between the drive shaft and driver and thus to increased reliability.
  • FIG. 1 shows an exploded view of a connection point between drive shaft and driver for a belt pulley
  • Figure 2 shows a drive shaft with an attached driver
  • FIG 3 shows a partial longitudinal section through the fastening region between the drive shaft and driver.
  • Figure 1 shows a drive shaft 1, a driver 3 for a pulley, not shown here, a mounting plate 5 and a clamping plate. 7
  • the configuration of the drive shaft 1 can be adapted on the one hand to the driving forces introduced into it and, on the other hand, to those which consumers are introduced to it.
  • the drive shaft 1 serves to introduce a torque into a pump, not shown here, in particular a CO 2 compressor of a motor vehicle.
  • the drive shaft 1 has at its first end 9 a stub shaft 11, the outer diameter of which is smaller than an adjoining region 13 of the drive shaft 1.
  • a stub shaft 11 the outer diameter of which is smaller than an adjoining region 13 of the drive shaft 1.
  • an abutment formed here as a shoulder 15 is provided, on the mounting disc 5 in the mounted state is applied.
  • the shoulder 15 could be provided as an abutment and a drive shaft 1 transversely penetrating pin.
  • the shaft stub 11 opposite the second end 17 is formed so that here in.
  • the drive shaft 1 introduced torque to a consumer, such as the compressor mentioned above, can be delivered.
  • the mounting plate 5 is attached in a suitable manner, for example by means of three fasteners 19, 21 and 23, which engage in corresponding recesses 25, 27, 29 in the driver 3.
  • fasteners screws, but preferably also rivets, can be used, which do not solve so easily with vibrations.
  • the mounting plate 5 has a central opening 31, the inner diameter is selected so that the stub shaft 11 can pass as free of play here.
  • the clamping disc 7 is designed as usual. It has a main body 33 with a central opening 35, from which emanate a number of radial slots, which do not extend to the peripheral line of the clamping disc 7. As a result, a number of spring tongues 39 are formed, which form an obtuse angle with respect to an imaginary plane in which the circumferential line of the clamping body 7 lies.
  • the main body 33 of the clamping disc 7 is made of a resilient material, preferably spring steel.
  • FIG. 1 shows the drive shaft 1 with the driver 3 mounted therein, which is connected to the mounting plate 5.
  • the clamping disc 7 of the driver 3 is held on the stub shaft 11 so that the mounting plate 5 rests with minimal axial play on the shoulder 15. It is best if an axial clearance is completely avoided. A game of 0.1 mm to 0.2 mm is acceptable. It is crucial that axial impacts on the attachment of the driver 3 are avoided.
  • the driver 3 has a disk-shaped base body 43 which is provided with radially extending to the stub shaft 11 ribs 45, between which a clearance 47 is formed.
  • an elastic element not shown here, can be introduced, via which a torque is introduced into the driver 3 via a pulley, not shown here.
  • the driver 3 can be made of plastic, but preferably of tiefziehpunem sheet metal.
  • FIG. 3 shows the fastening region between drive shaft 1 and driver 3 in longitudinal section.
  • the drive shaft shown here cut off, which penetrates the fixing plate 5 with its stub shaft 11.
  • fasteners of which, for example, the fasteners 19 and 21 can be seen attached to the driver 3.
  • the driver 3 is placed on the first end 9 of the drive shaft 1, so that the free end 11 penetrates the opening 31 of the mounting plate 5.
  • the clamping disc 7 is placed on the free end 41 of the stub shaft 11.
  • Their main body 33 is subjected to an axial force, so that it hangs firmly on the surface 49 of the mounting plate 5.
  • a drive shaft 1 can be connected to a driver 3 for a pulley, wherein after the assembly of the driver 3 on the drive shaft 1 at most a minimum initial axial clearance is given. So vibrations can not see axial shocks between driver 3 and drive shaft 1 lead, which could eventually cause damage. Shocks are already avoided because the clamping disc 7, the mounting plate 5 resiliently presses against the shoulder 15. If axial movements occur, they are resiliently intercepted by the clamping disk 7, so that impacts are avoided.
