Definitions

  • the invention relates to a wheel hub removal device for removing a wheel hub from a bearing located in a steering knuckle according to the features in the preamble of claim 1.
  • a Radnabendemontagevortechnisch of the generic type is from the DE 20 2004 010 887 U1 known.
  • two or three stud bolts are screwed into threaded holes in the hub flange.
  • a flange plate is determined.
  • the flange plate serves to hold a press unit.
  • a pressure plate is provided, which is supported by pressure pins on a support ring which is incorporated between the stub axle and the wheel hub. The pressure pins are inserted through the threaded holes, which are not occupied by the studs.
  • a Wheel hub with a five-hole flange and a use of three studs can therefore be used two pressure pin.
  • the known device has proven very well in practice. However, there are vehicles or vehicle types in which the extraction of the wheel hub with mounted joint or drive shaft due to the space-constrained conditions is difficult, because you can not get to the threaded holes in the Radflanschnabe to set the studs hereon. Also for dismantling sometimes so high extraction forces are required that the known disassembly device, because there can be used only two or three pressure pin, reaches its limits.
  • the invention is based on the prior art based on the object to improve a Radnabeterontagevorraum application technology, especially in terms of power transmission, and designed so that even such hubs can be removed in which a determination of the stud directly on the hub flange is not possible.
  • a flange adapter which is fixable on the wheel hub flange and projects circumferentially relative to the wheel hub flange, wherein in the flange adapter receptacles are provided for the stud bolts, via which the stud bolts are coupled to the flange adapter.
  • the flange adapter according to the invention creates opposite the wheel hub flange further outward recordings or connection options for fixing the studs. These can now be fixed to the flange adapter, which is connected to the hub flange. The rear flange plate is fixed to the stud bolt. Subsequently, the remaining device components are mounted.
  • a further advantage is that it no longer has to resort directly to the threaded bores in the wheel hub flange for fixing the stud bolts.
  • the stud bolts are mounted and fixed at the free end of the flange plate.
  • the pressure plate is positioned, which is supported on the support ring via the pressure bolts, which are inserted through the threaded holes in the hub flange.
  • the press unit is incorporated. Upon actuation of the pressing unit, the axial force generated thereby is transmitted via the pressure pin and the support plate on the steering knuckle and pulled out of the wheel hub from the bearing in the steering knuckle.
  • the flange adapter is annular and composed of two mutually coupled ring segments. This allows a simple and secure installation of the flange adapter even in confined spaces.
  • the flange adapter In the flange adapter an annular groove is formed.
  • the flange adapter engages around the outer circumference of the wheel hub flange with the annular groove.
  • the groove base rests against the outer surface of the wheel hub flange and the two side legs of the annular groove or the flange adapter engage around the wheel hub flange.
  • the ring segments of the flange adapter are connected by bolts extending in their plane.
  • the stability of the connection between the ring segments can be further increased if positive-locking elements are provided on the contacting abutment surfaces of the ring segments, which engage with each other. In this way, also a fit connection can be made.
  • the interlocking elements are formed by pins and pin holes.
  • a press unit which comprises a hydraulic cylinder and a threaded spindle.
  • the threaded spindle passes through with its base body a hole in the flange plate and is fixed to this.
  • the support ring which is installed between the stub axle and the wheel hub, is preferably also formed by two mutually coupled ring segments, which are connectable by means of bolts.
  • interlocking interlocking elements are provided on the contacting abutment surfaces of the ring segments. These also consist of pins and mortises, the bolts pass through the pins.
  • annular surfaces are provided in the support ring two remote via a step.
  • the annular surfaces have different diameters and are configured so that the support ring engages around the front end of the wheel hub. This is the inner ring surface on the front side of the steering knuckle. In this way, a stable fixing and support of the support ring is ensured on the steering knuckle.
  • the wheel hub 2 has a wheel hub flange 4 with threaded holes 5 and is seated with its hub neck 6 in a roller bearing 7, which is mounted in a bearing bore 8 of the steering knuckle 3.
  • the Radnabendemontagevorides 1 comprises a flange 9, which is indirectly supported via studs 10 on the hub flange 4 with the inclusion of a flange adapter 11.
  • the flange adapter 11 can be fixed to the wheel hub flange 4.
  • the flange adapter 11 is annular and can be assembled from two ring segments 12, 13 which can be coupled together.
  • the ring segments 12, 13 are connected by extending in its plane E bolt 14 together. These are guided by lateral holes 15 in the ring segment 12.
  • At the contacting abutment surfaces 16, 17 of the ring segments 12, 13 form-fitting elements 18 in the form of pins 19 on the ring segment 12 and pin holes 20 are formed on the ring segment 13 which engage with each other. As a result, a fitting connection between the ring segments 12, 13 is produced.
  • the pins 19 are designed sleeve-shaped, so that the bolts 14 can be screwed through the holes 15 through the pins 19 and the pin holes 20 into threaded holes 21 in the ring segment 13 and the ring segments 12, 13 can be clamped together.
  • the flange adapter 11 has a circumferential annular groove 22 and engages around the outer circumference 23 of the wheel hub flange 4 with the annular groove 22.
  • the groove base 24 bears against the outer surface 25 of the wheel hub flange 4.
  • the two side legs 26, 27 of the flange adapter 11 surround the wheel hub flange 4 and are laterally on this. In this way, a stable coupling of the flange adapter 11 is ensured with the hub flange 4, via which high tensile and compressive forces can be transmitted.
  • flange adapter 11 projects circumferentially relative to the wheel hub flange 4.
  • receptacles 28 are provided in the form of threaded holes into which the stud bolts 10 are each screwed with a threaded end 29.
  • the flange plate 9 can be fixed.
  • through holes 31 are provided in the flange plate 9, through which cylinder screws 32 can be passed and screwed into threaded bores 33 of the stud bolts 10 at the end.
  • the wheel hub removal device 1 further includes a pressure plate 34 which is positioned between the stud bolts 10.
  • the pressure plate 34 is supported via pressure pin 35 on a support ring 36, which between the stub axle. 3 and the wheel hub 2 is incorporated.
  • the pressure pins 35 are inserted through the threaded holes 5 in the hub flange 4 to rest on the support ring 36. At the wheel hub flange 4 facing away from the end 37 of the pressure pin 35, these engage in blind holes 38 of the pressure plate 34 a.
  • the stud bolts 10 are provided at their end 30 with a profiled corrugated portion 40.
  • the support ring 36 is also composed of two mutually coupled ring segments 41, 42, which are braced by means of bolts 43 with each other.
  • ring segments 41, 42 At the contacting abutment surfaces 44, 45 of the ring segments 41, 42 form-fitting elements 46 in the form of pins 47 and pin holes 48 are provided, which engage with each other.
  • the bolts 43 pass through the pins 47 and the pin holes 48 and are screwed into threaded holes 49 in the ring segment 42.
  • the support ring 36 has two offset over a step 50 annular surfaces 51, 52.
  • the support ring 36 thus surrounds the front end 53 of the hub neck 6, wherein the inner annular surface 51 abuts the end face of the steering knuckle 3.
  • the annular surface 52 extends at a distance to a shoulder 54 of the hub neck 6.
  • the pressing unit 55 comprises a hydraulic cylinder 56 and a threaded spindle 57.
  • the threaded spindle 57 has a base body 59 provided with an external thread 58 and is screwed with this into a provided with an internal thread 60 bore 61 in the flange plate 9.
  • an actuating polygon 63 is provided at the free end 62 of the threaded spindle 57.
  • a spigot 65 is provided at the hydraulic cylinder 56 facing the end 64 of the threaded spindle 57.
  • the hydraulic cylinder 56 can be pre-centered during assembly.
  • the Figures 2 and 4 show the Radnabeterontagevorraum 1 in the mounted state before pulling out the wheel hub 2 from the steering knuckle 3.
  • the hydraulic cylinder 56 of the pressing unit 55 By Actuation of the hydraulic cylinder 56 of the pressing unit 55 with pressure, the hydraulic cylinder 56 is extended. The force is transmitted to the pressure plate 34, which is supported on the steering knuckle 3 via the pressure bolts 35 and the support ring 36. The introduction of force leads to a displacement of the pressing unit 55 together with the flange plate 9 and the stud bolt 10 away from the steering knuckle 3, so that the wheel hub 2 is pulled out of the roller bearing 7 in the steering knuckle 3. This is in the Figures 3 and 5 clarified.
  • the hydraulic cylinder 56 If the available stroke of the hydraulic cylinder 56 is insufficient for pulling out the wheel hub 2, the hydraulic cylinder 56 is depressurized and the threaded spindle 57 is actuated. As a result, the hydraulic cylinder 56 is pressed back into its starting position. Subsequently, the hydraulic cylinder 56 can be pressurized again and the available hub be used again until the hub 2 is completely pulled out of the steering knuckle 3 and can be dismantled.
