Definitions

  • the invention relates to an airline unit for a hydraulic power steering, the construction principle is based on a pumping element that primarily in a housing made of light alloy!
  • the pumping unit consists essentially of a WeSSe. the runner. Wings, a curve ring and a Stirr ⁇ iatte. Depending on the model range, a second end plate or control plate is used here.
  • the axial end is formed by a lid, also made of light metal.
  • the shaft is guided in the housing by a Kugeiagerung and is connected to the runner located on it without play. In the radially arranged slots of the rotor, the inclusion of the wings takes place. The in the case or ceiling!
  • the crescent-shaped cam ring encloses the runner together with the lateral Sitrn- / Steuerplatie or the cover between the cylindrical peripheral surface of the rotor and the el ips ipsen-like bore of the cam ring are the two crescent-shaped pump chambers. Their volume results from the largest possible sickle segment between two wings and the width of the runner or the wings.
  • the oil flow generated in the crescent-shaped pressure chambers is due to the design of the longitudinal or transverse to the shaft positioned valves for pressure and
  • Volume flow limitation passed, limited to the set values and continued via a connected hose line to the hydraulic power steering.
  • the moment in the housing is guided by a Kugeiagerung.
  • the edge of the housing is bent over on the outer ring of the bearing.
  • the operating temperature for such pumps in vehicles is approximately 80 0 C. Due to the different thermal expansion coefficients of the materials of the housing and the bearing creates a greater radial and axial clearance at these temperatures.
  • a special EC bearing thermal expansion compensation or thermal expansion bearing
  • An EC bearing has two PA11 radial rings on the outside.
  • the vibrations of the engine cause strong longitudinal slamming.
  • forces of up to 60 g act on the components of the pump.
  • the axial play in the camp and the strong vibrations creates a Smulsskraft that can damage the pump.
  • the forces can be so great that the bearing is blown out of the pump, which means a complete failure of the pump.
  • the invention therefore has the object to avoid a failure of the pump through the camp and to reduce the cost of storage.
  • plastic When choosing the material for the axial compensation ring, plastic has proven to be the best solution.
  • metal TFT springs are unsuitable because they produce abrasion on the housing.
  • FIG. 1 shows the Detasi of the storage of Welie (1) of a rotary vane pump according to the prior art.
  • an expensive EG-bearing (3) is arranged in the housing (2) of the pump.
  • the EC bearing has externally two radial rings to compensate for the radial clearance.
  • FIG. 2 shows the detail of the storage of the WeHe (1) of a squeeze pump according to the invention.
  • the pump is a standard ball bearing (4) arranged soft axially by a plastic ring (5) is biased.
  • the plastic ring (5) axsal is arranged on the side facing the rotor of the pump side of the ball bearing.

Abstract

L'invention concerne une pompe à ailettes composée d'un élément pompe logé dans un carter (2) en métal léger. L'élément pompe comporte un arbre (1), un rotor, des ailettes, un anneau de came et au moins une plaque frontale, l'arbre étant logé par un roulement à billes dans le carter. Le jeu axial du roulement à billes est compensé par un anneau en plastique (5).
