Definitions

  • the present invention relates to a wheel drive, in particular for road pavers, with a drive shaft coupled to a drive motor and an output shaft connected to a wheel, the drive shaft and the output shaft being aligned parallel to the axis.
  • Such wheel drives are known. In particular, they are used in mobile construction machines to create road surfaces. These so-called road pavers have a bulk material pickup at one end and a processing device for manufacturing the roadway by means of the bulk material picked up at the other end. The bulk material is usually below the construction machine, d. H. below the wheel axles, transported from the bulk material pick-up to the processing device.
  • a disadvantage of pavement pavers of this type is that due to the low overall height of the known and previously used portal axles, the clearance below these axles is relatively small. As a result, however, only a limited amount of bulk material can be transported from the receiving device to the processing device. This in turn disadvantageously reduces the speed of work or production.
  • increasing the driving speed of the road paver during road manufacturing does not offer a solution, since this working speed cannot be increased arbitrarily while maintaining the specified quality standards. It is therefore an object of the present invention to provide a wheel drive of the type mentioned at the outset, which ensures an increase in the free space below the wheel axis of a construction machine.
  • a wheel drive according to the features of main claim 1 is used to achieve this object.
  • a wheel drive according to the invention has at least one intermediate shaft between an input shaft and an output shaft, the intermediate shaft being operatively connected to the other two shafts. Furthermore, according to the invention, the intermediate shaft is arranged axially parallel to the drive shaft and the output shaft, in such a way that a height offset between the drive shaft and the output shaft takes place relative to one another. The height offset between the drive shaft and the output shaft results in a significant increase in the free space below the drive shaft or the portal axis itself, since the available space is optimally used for the same height by the height offset of the drive shaft to the output shaft according to the invention.
  • two opposing wheel drives each form a portal axis, the portal axis forming a portal-like free space below two drive motors of the drive shafts which are each arranged independently of one another, and the free space being curved upwards in the direction of the drive motors like a hood.
  • Such an arrangement ensures that the space available underneath the portal axis is almost completely available as space for the execution of rubble.
  • the formation of two independently arranged drive motors for each wheel drive also increases the space available below the Portal axis at.
  • the two drive motors can be controlled independently of one another, which advantageously advantageously improves the steerability of the construction machine.
  • a two-stage shift stage is arranged between the drive shaft and the intermediate shaft, which enables a shift between a high and a low gear ratio or a first and a second speed. This ensures that, in addition to a low working speed, a relatively high driving speed of the construction machine is made available, whereby the possible uses of the corresponding construction machine are significantly increased.
  • the switching stage consists of two coaxial switching shafts, a coupling device being formed on the second switching shaft.
  • the clutch device consists of two single clutches, preferably two multi-plate clutches, which can be actuated hydraulically or mechanically.
  • the first selector shaft has a first gearwheel, the first gearwheel engaging in a counter pinion of the second selector shaft with the first clutch.
  • the first selector shaft also has a counter pinion, in which a second gearwheel of the second selector shaft engages with the second clutch.
  • the first clutch is connected to the counter pinion of the second selector shaft via a first cage
  • the second clutch is connected to the gear of the second selector shaft via a second cage.
  • a multi-disc brake is arranged coaxially with the output shaft.
  • a construction machine in particular a road paver, with a portal axle consisting of two wheel drives according to the type described above is also claimed.
  • Figure 1 is a schematic representation of two opposite wheel drives according to the invention.
  • Figure 2 is a schematic, partially sectioned illustration of the wheel drive according to the invention.
  • the wheel drives 10 shown schematically in FIG. 1 each have a drive motor 26 and a corresponding gear housing 56 and a rim 54, on each of which a wheel 16 is arranged.
  • the two wheel drives 10 form a portal axle 22.
  • Below the axle 22 there is a free space 24 which is surrounded by an axle cover 58.
  • the axle cover 58 consists of two side elements 60, 62 and a hood-like bulge 64 adjoining them at the top.
  • the hood-like design of the axle cover 58 is only possible through the design of the wheel drives 10 according to the invention. It is clear that the available space 24 below the axis 22 can be used optimally. Bulk goods are transported from one end of the construction machine to the other end in this free space 24.
  • FIG. 2 shows the wheel drive 10 in detail. It can be seen that the wheel drive 10 has a drive shaft 14 coupled to the drive motor 26, an output shaft 18 connected to the wheel 16 being aligned axially parallel thereto. Between the drive shaft 14 and the output shaft 18, an intermediate shaft 20 is formed, which on the one hand is operatively connected to them and on the other hand is also arranged parallel to the axis of the drive shaft 14 and the output shaft 18. It is clear that this results in a height offset between the drive shaft 14 and the output shaft 18 relative to one another.
  • the overall shape of the wheel drive 10 adapts to the spatial conditions specified by the wheel 16 and the rim 54. The same applies to the gear housing 56 of the wheel drive 10 or the axle cover 58 connected to it.
  • a two-stage switching stage 28 is arranged between the drive shaft 14 and the intermediate shaft 20.
  • the switching stage 28 enables switching between a high and a low gear ratio or a first and a second speed.
  • the low driving speed is d. H. the working speed of the construction machine in first gear 1 m / min.
  • the actual driving speed of the construction machine can be 20 km / h or more in second gear.
  • the shift stage 28 consists of two coaxial shift shafts 30, 32, a clutch device 34 consisting of two individual clutches 36, 38 being formed on the second shift shaft 32.
  • the mode of operation of the switching stage 28 is such that the first switching shaft 30 has a first gear 40 which engages in a counter pinion 42 of the second switching shaft 32 with the first clutch 36.
  • the first selector shaft 30 has a counter pinion 44, which is in a second gear 46 of the two th switching shaft 32 engages with the second clutch 38.
  • the first clutch 36 is connected to the counter pinion 42 of the second selector shaft 32 via a first cage 48.
  • the second clutch 38 is connected to the gear 46 of the second selector shaft 32 via a second cage 50.
  • the individual clutches 36, 38 are designed as multi-plate clutches.
  • the clutch device 34 is actuated hydraulically or mechanically, the clutch device 34 being closed with disk springs and opened with corresponding pistons.
  • one of the two individual clutches 36, 38 is always open. In the event of a pressure drop, however, both clutches 36, 38 close, the two clutches 36, 38 then serving as a safety parking brake.
  • the two clutches 36, 38 can also both be open. This is necessary, for example, when towing the construction machine. The opening takes place with a hydraulic system or mechanically via an emergency release device 76.
  • the drive motors 26 are hydraulic motors. The possibility of individually controlling the respective drive motors 26 significantly increases the steerability of the construction machine.
  • a multi-disc brake 52 is arranged coaxially with the output shaft 18 and serves as an additional wheel brake.
