Definitions

  • the rods that are conventional in conventional drives of wiper arms have the advantage that blocking forces that occur during operation of the wiper system can be absorbed by elastic deformation of the rods. Such a deformation, however, only occurs when the forces that occur during normal operation of the windshield wiper system are exceeded, for example in the case of a sudden load which occurs, for example, when large amounts of snow are removed from a windshield.
  • the sudden load on the wiper arms is also transmitted via the drive rod to those which are usually provided with teeth Gear means which are provided between the drive rod and the drive motor. Nevertheless, loads acting suddenly on the wiper arms can at least partially be absorbed by the elastic deformation of the drive linkage. Thus, voltage peaks can be reduced, which protects the gear means.
  • the axial forces that occur when the wiper arms are driven are conducted from the armature shaft via a securing element to the elastic element and from there to the inner ring of the roller bearing and via the roller body into the outer ring fixed to the housing and into the housing of the reversing motor.
  • the elastic elements are not deformed.
  • a transmission of axial forces into the housing of the reversing motor is possible through the arrangement of securing elements fixed to the anchor shaft and elastic elements on both sides of the inner ring, both with axial thrust forces in a first direction and in the opposite direction to this.
  • the axial forces can therefore be derived in both directions without deformation of the elastic elements in the housing of the reversing motor.
  • the axial thrust forces can be transmitted in a first axial direction via a first securing element fixed to the anchor shaft and a first elastic element to the inner ring of a first roller bearing and from there via the rolling element and the outer ring into the housing of the reversing motor.
  • the axial thrust forces are transmitted to the inner ring of the second roller bearing via the second anchor shaft-fixed securing element and the second elastic element and from there via the roller body and the outer ring into the housing of the reversing motor.
  • the elastic elements are coupled to sensors which detect the deformation of the elastic elements and are connected to a control of the reversing motor.
  • the sensors can be designed, for example, as pressure sensors and, when a limit pressure is exceeded, send a signal to the controller of the reversing motor, which then automatically switches off the reversing motor. In this way, simple overload protection can be implemented.
  • the forces required to deform the elastic elements 30 and 50 are smaller than the forces which would destroy the toothing of the worm shaft 12 and the worm wheel 14. Thus, destruction of the worm shaft 12 and the worm wheel is prevented by deforming the elastic members 30 and 50.
  • the remaining energy portion of the above Pulse energy can be introduced into the transmission housing 6 via the inner ring 42 and transmission via the roller body 44, the outer ring 46 and the stop 48.
  • a pulse denoted by direction 70 is transmitted from the wiper arm (not shown) via the output shaft 16 to the worm wheel 12 and thus to the worm shaft and the armature shaft 10.
  • the impulse then acts in the direction denoted by 66 and can be reduced via the shaft collar 32 and the deformation of the elastic element 30.
  • the remaining energy can be introduced into the motor housing 4 via the inner ring 24, the roller bodies 26 and the outer ring 28 and via the stop 34, so that destruction of the toothing of the worm shaft 12 and the worm wheel 14 is avoided.
  • FIG. 2 shows a second embodiment of a section of a reversing motor, in which only one roller bearing is used.
  • the bearing shown in FIG. 2 can be used, for example, in the reversing motor 2 shown in FIG. 1 at the height of the roller bearing 20 shown there. (Of course, additional bearings, preferably plain bearings, can also be provided in the arrangement according to FIG. 2.)
  • the reversing motor according to FIG. 2 has a motor housing 104, which is shown in sections, and an armature shaft 110, shown partially broken off.
  • the armature shaft 110 is mounted in the motor housing 104 via a roller bearing.
  • the roller bearing has an inner ring 124, roller bodies 126 designed as balls and an outer ring 128.
  • the elastic elements 130 and 150 are deformed. In order to reduce an impulse force that acts in the direction designated 162, the elastic element 130 deforms; to reduce an impulse force, which acts in the direction designated 166, the elastic deforms Element 150. This prevents the teeth of worm shaft 12 and worm wheel 14 from being destroyed.

Abstract

L'invention concerne un moteur réversible (2), entraînant notamment une installation d'essuie-glace, en particulier sur un véhicule à moteur. Ce moteur est équipé d'un arbre d'induit (10) soumis à des forces de poussée (62, 66) et logé dans deux paliers à roulement (18, 20) dont les bagues intérieures (24, 42) sont disposées sur l'arbre d'induit (10) au moyen d'un siège coulissant. Dans le sens axial, sur chacune des faces orientées l'une vers l'autre ou en opposition mutuelle des bagues intérieures (24, 42), se trouve un élément élastique (30, 50) appuyant contre un élément de sécurité (32, 52) solidaire de l'arbre d'induit, ces éléments élastiques servant à transmettre les forces de poussée (62, 66) aux bagues intérieures (24, 42) et des bagues intérieures au carter (4, 6) du moteur réversible (2), par l'intermédiaire d'éléments de roulement (26, 44) et de bagues externes (28, 46) fixées au carter. Les éléments élastiques (30, 50) ne se déforment que sous l'action de forces de poussée (68, 70) supérieures aux forces de poussée (62, 66) développées lors du fonctionnement normal du moteur réversible.
