Definitions
- the invention relates to a belt drive arrangement for an internal combustion engine, comprising a drive pulley, which is driven by a crankshaft of the internal combustion engine, a first driven pulley, with which a first auxiliary unit can be driven, a second driven pulley, with which a second auxiliary unit can be driven, and an endless belt, which an inner side and an inner side of the opposite side comprises and wrapped around the drive pulley and the driven pulleys at least in sections as Umschlingungsgetrle.
- the invention relates to an internal combustion engine with such a belt drive arrangement.
- ancillaries are, for example, the water pump, which circulates the coolant of the engine and thus contributes to the regulation of the engine temperature, the generator or the alternator, which is required for the supply of the electrical system ⁇ the Kärteffenverêtr, which is used to operate an air conditioner, hydraulic pumps for the operation of a power steering, fans for the cooler, etc.
- the ancillaries are via drive pulleys or Drive wheels driven by the crankshaft of the internal combustion engine .. In today's automotive industry belt drives are used, which transmits the drive power from the crankshaft to the ancillaries.
- the invention proposes a Riementriebanord- ⁇ voltage for an internal combustion engine having a drive pulley, which is driven by a crankshaft of the internal combustion engine, a first driven pulley, with a first auxiliary unit can be driven, a second driven pulley, with a second
- An accessory is drivable and includes an endless belt.
- the belt has an inner side and an outer side lying opposite the inner side and, as a belt transmission, wraps around the drive disk and the output disks at least in the opposite direction. section-wise.
- the belt, the drive pulley and the first driven pulley with. enclose its inside in Berschreibendem contact and wrap the second driven pulley with its outside in touching contact.
- the belt contacts with its inside the drive pulley, which is driven by the crankshaft and a first output disk "drives a first auxiliary unit and with the belt skirts the second driven pulley, with which a second Mauäggre- is gat driven.
- the wrap of the driven pulley can be performance related, wherein the first auxiliary unit, which is connected to the first driven pulley, has a higher power and the second auxiliary unit, which is connected to the second driven pulley, has a lower power consumption.
- the higher the power consumption of an auxiliary unit the higher the load torque that generates this accessory in the belt drive.
- the belt thus wraps around drive pulleys which are connected to ancillary units which constitute a high load moment with an inner side.
- Output disks which are connected to an accessory that generates low Lastmomertte in the belt, are wrapped by the back with the outside or with the belt.
- a tensioning roller can be arranged in the direction of rotation of the belt after the second driven pulley, which pulley is wrapped at least in sections with the outside of the belt.
- the auxiliary units can be arranged such that, for each unit, the wrap angle is equal to the power consumption or the load torque of the machine. gregats is adjusted. This is made possible by the positioning of the.
- Tension pulley is an accessory that generates a low load torque and an accessory that generates a higher load torque. The function of the tensioner in the wrapping direction after an auxiliary unit with low power consumption is made possible by the low induced load torque generated by the auxiliary unit.
- tension roller between the first driven pulley and the second driven pulley can be arranged.
- Tension pulley in front of an auxiliary unit ml with a high load torque additionally has the advantage that at maximum load of this auxiliary unit, the looping on the associated driven pulley is increased.
- the belt is elongated as the load torque of the accessory increases.
- the tensioner adjusts and thereby increases the wrap around the output gear of the associated auxiliary unit.
- a third driven pulley may be provided, which is connected to a third auxiliary unit, wherein the third driven pulley is wrapped with an inner side of the belt.
- the belt when installed can describe a substantially L-shaped orbit.
- first auxiliary unit may be a generator and the second auxiliary unit may be a water pump.
- the third auxiliary unit may be formed as a refrigerant compressor.
- the invention relates to an internal combustion engine for a motor vehicle comprising a belt drive arrangement described above.
- the invention is explained in more detail below with reference to the description of the figures.
- the claims, the figures and the description include a variety of features "which are explained in the following in connection with exemplary embodiments described of the present invention. The person skilled in the art will also consider these features individually and in other combinations to form further embodiments that are adapted to corresponding applications of the invention.
- Fig. 1 is a side view of a belt drive assembly
- FIG. 2 is a perspective view of a belt drive arrangement.
- the belt 20 is formed as a closed Endtosriemen and has an inner side 21 and an outer side 22. With its inner side 21 of the belt 20 wraps around a drive wheel 11 which is rotatably connected to a crankshaft, not shown, of an internal combustion engine. By the rotation of the crankshaft, the drive wheel 11 is rotated and the belt 20 taken in the direction of rotation R. With its inner side 21 of the belt 20 also wraps around a first output gear 12 and a third output gear 14. With its outer side 22 of the belt wraps around a second output gear 13 and a tension roller 15. The output gears 12, 13, 14 are rotationally fixed or via a freewheel each connected to an auxiliary unit.
- the first drive wheel 12 is connected to a generator, the second drive wheel to a water pump 13 and the third drive wheel 14 to a refrigerant compressor.
- the Hubwheels 12, 13, 14 are set in rotational motion and thus the
- the belt 20 may be a toothed belt, V-belt or V-ribbed belt.
- the teeth or the ribs on the inner side 21 and the belt front side are arranged.
- the outer side 22 or der- belt back then generally has no elevation and is flat.
- the surface of the belt back 22 may also be roughened, provided with a structure or constructed analogously to the inner side 21.
- the second output gear 13 is looped by the belt 20, wherein the outer side 22 of the belt is in touching contact with the output gear 13, only a lower torque or a lower power can be transmitted here. Consequently, according to the invention a performance-related arrangement of the ancillaries is generated, with ancillaries that exert a high load torque on the belt 20, are wrapped by the inner side 21 and accessories that a low load torque in the belt. 20 are entangled from the outside 22 of the belt 20. Since the drive torque is relatively high, and the drive wheel 1 1 is wrapped with the inside of the belt.
- the belt 20 in the installed state has a substantially L-shaped contour.
- the drive wheel 11, the first driven gear 12 and the third output gear 14 are such excluded each other 'oriented such that they form a triangle.
- the belt is deflected in the area between the drive disk 11 and the driven pulley 12, so that the essentially L-shaped course results. Consequently, the second output gear 13 acts as a deflection roller in the sense ofrolsgration. As a result, a sufficient clamping force can be generated in the belt 20, while reducing the space requirement.
