Definitions

  • the invention relates to a fan drive for the cooling system of a motor vehicle, in which the Centrifugal fan in the center of a box-shaped cooling system, consisting of several coolers for different media, is arranged, the drive member in the rear wall of the cooling system is mounted and has a driven pulley with a driving pulley on a shaft of the drive machine of the motor vehicle by means of V-belts or the like connected is.
  • V-belts which are between one Pulley on the crankshaft of the engine and a pulley on the shaft of the fan are arranged.
  • the V-belt also runs over a movable tensioning pulley.
  • the the movable tension pulley and the driving pulley are attached to the motor housing.
  • the engine drives other auxiliary machines such as water pumps, hydraulic pumps, Compressors and generators, which in some cases creates a structural narrowness that Accessibility impeded in the event of inspection and maintenance activities.
  • the present invention is based, the cooling system is attached to the frame of the motor vehicle and the Fan stored on the cooling system. This principle is also shown in the aforementioned DE 41 17 336 A1.
  • the cooling system and the fan are attached directly to the engine, while the third principle the cooling system is attached to the frame and the fan to the crankshaft of the Motors has stored.
  • the fan drive described at the beginning corresponds to WO 98/45600, which also relates to a box-shaped cooling system and also belongs to the first principle described. However, there is no constructive solution for the drive specified, but only in general from a belt drive.
  • the object of the invention is to design the fan drive so that the cooling system remains very compact, ensures safe continuous operation and assembly advantages for the Manufacturer of motor vehicles offers.
  • the rear wall has struts which are in the center, within the cooling system converge, where the drive element of the fan is mounted, being outside a center connected to the rear wall is arranged on which the fulcrum a tension lever is located, which carries a tension roller and that the driving, the driven Pulley and the tension pulley are arranged in front of or in the plane in which the rear edge of the Radiator or the rear edge of the rearmost protruding radiator of the cooling system lies.
  • the tension pulley is rotatably supported at one end of a tension lever, at the other end Clamping elements are arranged, which consist of a tension spring and a working cylinder.
  • the Tension lever itself is mounted at a fixed point on the rear wall or a support strut, so that it can be pivoted about this point.
  • the mainspring is used to maintain the Belt tension during operation, while the preferably pneumatic working cylinder can bring the tensioning lever and thus the tensioning roller into a position in which changing the V-belt is easily possible.
  • a pneumatic cylinder is particularly advantageous if the Cooling system for trucks is provided because they have compressed air, which also in the The truck is at a standstill and can be used.
  • the through the driven pulley of the fan, through the driving pulley and the level formed by the tensioning roller is located within the retracted rear wall, so that very little additional space is required. Lateral relative movements are also possible, the movable tensioning roller ensures that the V-belts in all operating situations are under optimal tension. However, it is also possible to move the tension pulley outside the plane of the To arrange pulleys, however, all the parts described are intended according to the invention or are in the plane where the rear edge of the radiator or the furthest back arranged cooler. The size of the possible offset of the pulleys and Tensioner pulley will practically move within relatively small limits.
  • pulleys can also be arranged offset to one another if the installation or the space in the motor vehicle that require.
  • the driving pulley is simple with the connecting flange on the crankshaft To connect drive machine.
  • the distance between the engine and the cooling system is significantly reduced, which saves installation space.
  • the cooling system is equipped with the complete fan drive, which now is part of the same, so that when mounting it in the motor vehicle only its attachment to Frame of the motor vehicle and the connection between the drive member, the drive flange on the crankshaft of the engine, and the connection flange mentioned on the cooling system must be done.
  • the pulleys can be multiple pulleys be and / or offer the possibility of transmitting the torques and Varying speeds, e.g. B. in that one of the pulleys is formed in two parts and two parts can be pushed together or apart depending on the torque can, causing the V-belt running in the pulley closer or farther to the axis of the Pulley shifts, which leads to changed speeds.
  • the necessary ones Devices are part of the prior art. A belt drive that offers these possibilities works for example from EP 0 020 005 and therefore need not be described in more detail.
  • the drive element of the fan can be a drive shaft.
  • the drive member should preferably be a continuously switchable clutch, for example a viscous coupling or an electromagnetic coupling. This makes training unnecessary the pulley with speed-changing features or properties.
  • the number and arrangement of the support struts of the rear wall which are generally designed as profiles the rest of their design can be different.
  • the back wall becomes a four-sided Be frame construction.
  • it is also possible to dispense with the four-sided frame for example four Guide struts in a star shape from the corners to the center, as in the previous one unpublished application DE 199 50 753.8 was shown.
  • the formation of the back wall there should - at least with regard to the arrangement of the support struts - also for the present application be used.
  • the supporting structure of the rear wall is preferably made of aluminum and can be designed as a welded construction as well as in die cast aluminum.
  • the cover between the support struts can be made of plastic or aluminum sheet.
  • the cover has stiffening beads or the like which increase the stability the light metal construction are known.
  • the rear wall 8 is a frame construction, the four sides 25 to 28th has, which consist of profiled aluminum.
  • Three struts 12, 13 and 14 extend to Center 3, in which the drive member 7 of the fan 2 is rotatably mounted.
  • Fig. 2 In the shown The embodiment is the drive member 7 a continuously switchable electromagnetic clutch.
  • the clutch 7 is equipped with a driven pulley 9 and with on the output side the impeller of the fan 2 connected.
  • a carrier 15 is connected to the center 3. At a Not shown embodiment, the carrier 15 is not with the center 3 but with the Frame construction of the rear wall 8 connected.
  • the pivot point 16 or pivot point of the clamping lever 17 has been provided on the carrier 15.
  • One end 20 of the tensioning lever 17 carries a tensioning roller 18.
  • the tensioning roller is 18 connected to a ball bearing 29 at the end 20 of the clamping lever 17.
  • the pivot point 16 of the Tensioning lever 17 is of a conventional type.
  • a tension spring engages at the other end 21 of tensioning lever 17 23 and a pneumatic cylinder 24 as shown in FIGS. 1, 3 and 4.
  • the tension spring 23 and the pneumatic cylinder 24 have a common abutment 32 on the Support strut 12 on.
  • the pneumatic cylinder 24 is only attached to the abutment 32 been while a rail 34 has been provided for the function of the tension spring 23, the at its end has a counter bearing 35 for the tension spring 23, which over the operation of the cooling system 1 the tension lever 17 receives forces acting on the tension spring 23.
  • the piston rod 33 of the double-acting pneumatic cylinder 24 is extended, whereby the Tension lever 17 rotated about the pivot point 16 and the tension roller 18 assumes a position in which the V-belt 11 can be removed.
  • a known clamping element 22 are used, both Functions united. Such a clamping element 22 that a tension spring with a Damping element is z.
  • pivotable counter bearing 32 must be provided in order to be able to change the V-belt 11.
  • cooler 6 that the cooling system has different coolers 4, 5 and 6.
  • the cooler shown is located opposite the cooler 6, so that the cooling system 1 on all four sides has a cooler.
  • the cooler 6 and the cooler 5 may be a common coolant cooler.
  • the upper cooler 4 a charge air cooler.
  • the charge air cooler 4 has a rear edge 30, which is located in the level 31.
