Definitions

  • the invention relates to a method for mounting an electrical machine, in particular a generator or a starter mechanism as a starter, for starting a combustion engine.
  • the present inventions starts out from a starter, in particular from a coaxial starter, for starting a combustion engine, in particular for motor and/or utility vehicles and a connection assembly for a force transmitting connection of two components of the connection assembly, as for example a push-on pinion connection for mounting a put-on pinion on a corresponding shaft according to the generic term of the independent claims.
  • Object of the present invention are starters and starting mechanisms for vehicles having combustion engines comprising an electrical machine having an anchor and a commutator/collector, wherein the anchor has an anchor shaft and a corresponding anchor bearing.
  • an object of the present invention is a motor vehicle starter having an electric motor and an engaging system, for example according to a free ejective starter or a -type starter.
  • Starter motors having a starting relay for vehicles with combustion engines are well known from prior art.
  • Such starter motors comprise generally a direct current electric motor for starting the combustion engine.
  • Starting mechanisms known from prior art comprise a free wheel gear(-box) having a rotatable pinion, which is supported with clearance.
  • Corresponding starters for passenger cars and utility vehicles are well known. Those cars and vehicles comprise a starter pinion that is put on a pinion shaft, wherein the starter pinion is driven from the pinion shaft by a positive connection, in particular by a serration.
  • Those starters are for example known as free ejective starters.
  • starters for start-stop-applications comprise this kind of push-on pinions, wherein such starters are arranged as nose-type starters.
  • an axial fixing of this kind of starters is formed by a spring-lock washer or retainer or a combination of retainer and stop ring.
  • a starter having a free-wheel gear with a bayonet locking comprising a spring bearing provided at a pinion in front thereof, a spring bearing provided at a pinion shaft in the rear of the spring bearing and in front of a second helical spline and a cushion spring being interposed between the two spring hearings.
  • the cushion spring can be mounted in front of the pinion and the second helical spline. Therefore, as the distance between the first and the second helical splines can be shortened and an equivalent bending moment acting from the pinion to a pinion clutch at the time of engine cranking can be reduced. Moreover the load stress that acts on each part of the pinion shaft and the pinion clutch can be reduced.
  • the axial distance limitation may be used for different connection assemblies having different geometries, especially different length. Due to the adjustable stop being adjustable in an axial direction the stop matches to all kind of connection assemblies having different length.
  • the adjustable stop is limited with regard to its width in axial direction but is adjustable with regard to its position relatively to one or both of the pinion or the pinion shaft. By this a safe axial limitation is guaranteed.
  • the electric machine or electrical machine is formed as a starter motor having a bayonet locking for realizing a pinion stop function.
  • the bayonet locking and the dependent bayonet design are based on three main characteristics. First an internal spline on the starter motor pinion and/or in the overrunning clutch (short: ORC) that has half of the teeth specified for its diameter.
  • an external spline at the driven shaft or pinion shaft has corresponding spline geometry in a front area that has half of the vacancies specified for its diameter.
  • the bayonet locking and/or the bayonet design according to the present invention improve the system balancing and the strength regarding high speed conditions. Further the bayonet locking does not depend on the position of the ORC inside the starter.
  • the assembly process can also be improved. Instead of using washers on the back part of the pinion a fixed stopper is used on the front part of the driving shaft. Thus an improved balancing and an improved strength against high speed conditions are realized. Further the solution is not dependant on the ORC position inside the starter motor.
  • the assembly process is improved. Additionally the number of components is reduced.
  • Last but not least the stop component can be designed to also perform a sealing function.
