Definitions
- the invention relates to a device for driving units an internal combustion engine, such as a water pump and fan, via a belt drive that can be driven from the crankshaft.
- an internal combustion engine such as a water pump and fan
- auxiliary units such as. a water pump, an alternator, an air conditioning compressor or other ancillary units are mostly used driven by a belt drive together with a belt.
- the present invention is therefore based on the object to improve a device of the type mentioned at the outset in such a way that the fan is driven independently of the basic association can and that forces and loads of the fan do not affect the basic association.
- the drive of the fan is now from the basic association Cut. This means that for one thing there are no repercussions done on the basic unit and secondly that any Desired speed ratios for the fan possible are, although it is also driven by the crankshaft becomes.
- the relative rotatability can e.g. by a Rolling bearing device, e.g. a ball bearing, done in between is switched. Basically, this is the drive shaft for the fan itself in a proven manner coaxial to the crankshaft, however, uncoupled from it accordingly.
- Another advantage of the invention is that this results in cost and weight reductions. Translations for the fan are both ins Slow "as well as ins Fast "possible.
- a first pulley 2 On a crankshaft 1, which is only in principle in FIG. 1 is shown, a first pulley 2 is arranged, the due to the connection with the crankshaft 1 at engine speed circulates.
- a V-belt 3 connects one on a water pump shaft 4 a water pump 5 arranged second V-belt pulley 6 with the first pulley 2.
- the one over the second Belt pulley 6 guided V-belt 3 drives in a known manner further auxiliary units, such as an air conditioning compressor 7 and one Alternator 8, each with associated pulleys.
- a tension pulley 9 between the first V-belt pulley 2 and the air conditioning compressor 7 provides the required voltage of the V-belt 3.
- V-belt 3 closes again the V-belt pulley 6 of the water pump 5 back.
- the pulleys 2 and 6, the water pump 5, air conditioning compressor 7 (if present) and alternator 8, together with these V-belts 3 connecting units to each other form a basic structure or first belt drive.
- the third pulley 10 is via a second V-belt 11 with a fourth V-belt pulley 12 in drive connection and forms a second Belt drive.
- the fourth V-belt pulley 12 is with a connecting flange 13 provided, which is arranged on an intermediate shaft 14 is.
- a roller bearing and ball bearing connection 15 is the Intermediate shaft 14 mounted inside a driver 16.
- the Driver 16 is with the first V-belt pulley 2 connected via screw connections.
- This type of mounting makes the fourth V-belt pulley 12 arranged coaxially to the crankshaft 1, but from this uncoupled so that they are independent of the speed of the crankshaft 1 is.
- the speed of the fourth pulley 12 and thus connected connecting flange 13 depends on the Translations via V-belt pulleys 2, 6, 10 and 12 or their diameters to each other. This way, any one can given translation i can be set.
- the flange 13 is with a coupling, e.g. a viscous coupling, 17 connected, the coaxial to the intermediate shaft 14 and so that it is also coaxial to the crankshaft 1.
- a coupling e.g. a viscous coupling
- 17 On the clutch 17 a fan 18 is arranged. Structure and mode of operation the clutch 17 and its connection to the fan 18 generally known, which is why it is not discussed in more detail here becomes.
- the drive of the fan 18 via that on the water pump shaft 4 arranged pulley 10 and the co-axial to the crankshaft 1st fourth pulley 12 supported on the intermediate shaft 14 is independent of the basic association. This applies to both Effects of forces as well as the possibility of other gear ratios to create for the fan drive.
