Definitions

  • the invention relates to a method for fixing a retaining disk on a torque transmission part.
  • the invention further relates to a torque transmission part with a fixed retaining disk for starting devices and a starting device comprising the torque transmission part.
  • starters or starters are used, which are fed with a separate from the fuel supply power supply.
  • electric motors usually used, the starting pinion is first meshed in the ring gear of the internal combustion engine to turn the internal combustion engine. The electric motor then accelerates via the starter pinion the ring gear of the internal combustion engine until it can continue to run without support.
  • the freewheel thus provides an overtaking opportunity for a starter pinion when the engine is started and rotates faster in the decompression phase than a starter motor pretends in the starter.
  • roller freewheels that connect the starting pinion on the output shaft with a driver on the drive shaft.
  • DE 10 2009 001 738 A1 describes a roller freewheel for a starter of an internal combustion engine.
  • a guide disc closes spaces from a trained with a guide part roller freewheel.
  • a holding plate which serves the axial securing of the Andrehritzels.
  • the retaining disc also prevents the escape of Lubricant.
  • a driver holds together with a positively secured locking cap the freewheeling parts in an interior.
  • the retaining plate is fixed during assembly of the freewheel by stamping the cap.
  • different mounting washers must be used during assembly of the freewheel.
  • the thickness, the inner and the outer diameter of the retaining washer to the tip circle of the pinion gear and outer diameter of the freewheeling track must fit.
  • This increases the production cost, since in the freewheel assembly a variety of different retaining disks must be stored and mounted. Ultimately, this results in a certain risk that wrong retaining washers are installed in the freewheel assembly.
  • the method proposed according to the invention makes it possible to attach the at least one retaining disk to the torque transmission part before the freewheel mounting. That the torque transmission part is provided after its production directly with at least one matching retaining disk. Only then are the components of the freewheel, the driver and the cap mounted on the torque transmitting member. Consequently, it is inevitable for each pinion-freewheel combination to assign the designated holding plate (s) with the correct diameters and the correct thickness.
  • the diameter of the retaining plate (s) for the axial securing is important.
  • the thickness of the retaining disc (s) is relevant for the Einspurvorgang. Because with a too thick disc could (n) the holding disc (s) or the freewheel in the meshed state butt against the ring gear of the internal combustion engine and thus cause damage.
  • the installation of the holding disc (s) can be made more reliable by assigning the right holding disc to each starting pinion already before free-wheel mounting.
  • the possibility of obstructing false holding disks due to the large number of possible combinations is thus greatly reduced.
  • the at least one retaining disk is fixed by bending in the at least one recess of the torque transmission member so that the inner diameter of the at least one retaining disk is smaller than the outer diameter of the torque transmitting member and the inner diameter of the at least one retaining disk is greater than the outer diameter of the recess ( en) in the torque transmission part.
  • the outer diameter of the recess (s) in the torque transmitting member and the inner diameter of the at least one retaining disk in the fixed state is further selected to provide a clearance fit between the at least one retaining washer and the recess (s) in the torque transmitting member. In this case, there is a clearance fit when the at least one retaining disk is rotatably fixed to the torque transmission part.
  • the inner diameter of the at least one retaining disk is thus greater than the outer diameter of the recess (s) of the torque transmission member.
  • the at least one holding plate is bent by means of a stamping tool in the at least one recess and thus fixed captive. This step is particularly facilitated if the at least one retaining disk has been pushed in a soft state.
  • a soft state is to be understood as meaning any state in which the at least one holding disk is plastically deformable. This can be achieved, for example, if the at least one holding disk is hot and the material from which the at least one holding disk is made is still plastically deformable.
  • the at least one retaining disk can be bent radially after pushing in a particularly simple manner by means of a stamping tool, ie the inner diameter of the at least one retaining disk is reduced by the bending. After cooling, the at least one retaining disk then sits captive in the at least one recess of the torque transmission part.
  • the invention proposes a torque transmission part for receiving a freewheel, in particular for starting devices comprising a pinion, an inner ring and at least one recess which is provided circumferentially on an outer diameter of the torque transmitting member, wherein at least one retaining disc is received in the at least one recess on the torque transmission part ,
  • the torque transmission part proposed according to the invention can be used, in particular, for installation in starters, wherein the at least one retaining disk is provided on the torque transmission part before the freewheel is mounted.
  • the torque transmission part according to the invention thus makes it possible to reduce the production cost. Also, the mounting of the retaining washers is greatly facilitated and thus made the production reliable.
  • the torque transmission part is formed in one piece or in several parts.
  • a one-piece design has the advantage that fewer assembly steps are required, with a multi-part design supports the common part concept, since a higher flexibility in the combination of components is possible.
  • the at least one retaining washer is seated with a clearance fit in the at least one recess of the torque transmission part. The clearance fit between the at least one retaining washer and the at least one recess of the torque transmitting member allows the at least one retaining washer to be rotatably fixed to the torque transmitting member. This is necessary so that a decoupling between the Anund output shaft can take place through the freewheel.
  • the at least one retaining disk has at least two sections of different thickness in the radial direction.
  • the at least one retaining disc can be configured in this embodiment so that the guide pulley of the freewheel is integrated into the at least one retaining disc. This reduces the number of parts to be mounted on the torque transmitting member and thus facilitates the later assembly of the freewheel.
  • the at least one retaining disk made of a metallic material such as spring plate and / or a plastic.
  • the materials used for the production of retaining disks must be temperature resistant, since in the freewheel strong temperature fluctuations can occur. For example, the friction of the freewheel generates temperatures up to 180 ° C. The installed materials are thus subject to heavy loads.
  • the at least one retaining disk can be provided with a coating which provides additional protection for the at least one retaining disk. Coatings such as SiC, bonded coating, diamond coatings such as DLC (Diamond like carbon), Bornitrit with phosphate, titanium nitrite or hard chrome are conceivable as a lubricant in the freewheel.
  • a starting device for internal combustion engines which comprises a torque transmission part with at least one built-in retaining disc in the at least one recess before the freewheel assembly, has the advantage that the effort in terms of holding disks is significantly reduced, thereby increasing the efficiency of the production of starting devices.

  • the section which is arranged in the sliding bearing 104 of the intermediate bearing 101 is followed by a section with a straight toothing 125 (internal toothing), which is part of a shaft-hub connection 128.

  • the retaining disc 210 may be made of simple sheet metal, such as spring steel, or plastic.
  • the radial bending 232 of the retaining disk 210 can be achieved by any manufacturing method known to the person skilled in the art, which applies a bending moment to, for example, a metal sheet and thus effects the at least partial folding over of a surface part. Examples of such processes are stamping, deep drawing, laser bending or any other bending process.
  • a holding plate made of plastic can be produced by injection molding or similar methods directly in the radially bent state. The goal of these methods is to reversibly reduce the inner diameter 218 of the retaining disk 210, so that it can be pushed onto the torque transmission part 212.
  • the sliding of the retaining disk 210 on the torque transmission part 212 may from the direction of the starter pinion 22 or, as in FIG. 4 indicated by A, take place from the direction of the inner ring 140 with outer diameter 238.

  • a stamping tool 222 At the level of the recess 214 is then a stamping tool 222, as in FIG. 4 indicated, appropriate.
  • the bent retaining disk 210 is preferably in the soft state at least partially straightened straight again, so that the inner diameter 218 of the disc decreases. In this way, the retaining disk 210 can be fixed with clearance fit in the recess 214 on the torque transmitting member 212.
  • clearance is to be understood as meaning that the retaining disk 210 is captively inserted in the recess 214 and permits relative movements. Accordingly, the retaining disk 210 is not seated in an interference fit on the torque transmission part 212. The disk can thus move axially within the recess and around the in FIG. 4 Rotate the horizontal axis of the torque transmission member 212.
  • the retaining disk 210 is still in the soft state after being pushed onto the torque transmission part 212. This facilitates the bending and thus simplifies the fixing of the retaining disk 210.
  • FIG. 5 shows the torque transmission member 212 produced by the above-described method, to which a holding plate 210 is mounted in the recess 214.
  • This part can be produced by means of the inventive method, regardless of the freewheel assembly. Since the different retaining washers 210 are previously applied to the torque transmitting member 212, the reliability of production can be increased. Thus, due to the different diameters, the possibility of incorrect assembly is lower, since, when pushed on, the inner diameter 218 of the radially bent retaining disk 210 must fit over the outer diameter 216 of the torque transmission part 212. This can be considered overall as a backup that protects against the installation of false holding disks 210.
