Les moyens couramment employés pour obtenir ces

  
deux vitesses peuvent être divers et comporter par exemple

  
 <EMI ID=4.1> 

  
d'une boîte de vitesse, d'un dispositif a double embrayage,

  
ou encore d'un mécanisme a une ou deux poulies variables*

  
La plupart de ces moyens nécessitent une commande mécanique dont l'agent moteur" dans le cas d'une machine

La présente invention a pour objet un dispositif  de commande de changement de vitesse Utilisent un petit  moteur électrique de faible puissance et qui ne présente

partiel, des positions différentes de la came de commande"*  La figure 3 est une vue schématique, en perspective <EMI ID=11.1> 

  
 <EMI ID=12.1> 

  
Sur la figure 1, on voit que le variateur de vitesse   <EMI ID=13.1> 

  
que réunit une courroie 3, La poulie variable 1 est clavette sur l'arbre du moteur principal 4, qui entraîne le tambour 5 de la machine par l'intermédiaire du variateur de vitesse

  
 <EMI ID=14.1> 

  
 <EMI ID=15.1>  .Le flasque mobile de là poulie variable 1 peut être entraîna dans un mouvement de translation axial priée  une butée 9, solidaire d'un levier 10, de telle tort@ que la courroie 3 se place au diamètre désirée Le levier 10 <EMI ID=16.1> 

  
est entraînée par une tringlerie 12, elle-même actionnée

  
 <EMI ID=17.1> 

  
 <EMI ID=18.1> 

  
Un jeu de contacts 20, 21 , 22, solidaires de

  
Marbre de sortie, par lesquels passe le courant d'alimentation du petit moteur 16, permet d'immobiliser la came 13  dans la position voulue. 

  
pans le présent exemple, trois vitesses sont prévues  auxquelles correspondent trois positions de la came de commande 13, à savoir la position "lavage" représentée  sur la figure 2a (poulie 1 réglée au diamètre effectif  minimum) ; là position "vidange" à vitesse intermédiaire ' 

  
 <EMI ID=19.1> 

  
que montre la figure 2c. En alimentant successivement et séparément les fils B, C et A, on obtient, dans l'ordre, la vitesse de vidange, la vitesse d'essorage et le retour à la vitesse de lavage. / 

  
Les contacts 20, 21 et 22 sont commandés par une came 23 et, si cela est nécessaire, on peut agencer cette came de telle sorte qu'il se produise un verrouillage électrique entre la position de vitesse de lavage et la  position de vitesse d'onsorage, c'est-à-dire qu'il soit

  
 <EMI ID=20.1> 

  
der la vitesse intermédiaire pour atteindre la vitesse d'essorage.

  
Bien entendu, plus de trois vitesses peuvent être prévues si cela est jugé nécessaire. 

  
La figure 3 montre avec plus de détails le mécanisme de liaison élastique entre le groupe moteur de commande 14 et le levier 10,

  
Le levier 10, tiré par le ressort 15 qui est tendu d'une certaine valeur, vient en butée sur un écrou 24,

  
vissé sur la tringle 12.

  
L'écrou 24 permet un réglage de position du levier
10, donc de la butée 9, ce qui donne la possibilité  d'ajuster les différentes vitesses aux valeurs désirées, 

  
Le ressort 15 permet de limiter les efforts d'arcboutement lorsque la came 13 est au point mort,

during washing, the other fast, used during the east *. rogue

  
The means commonly used to obtain these

  
two speeds can be different and include for example

  
 <EMI ID = 4.1>

  
a gearbox, a double clutch device,

  
or a mechanism with one or two variable pulleys *

  
Most of these means require a mechanical control including the driving agent "in the case of a machine.

The present invention relates to a speed change control device Using a small electric motor of low power and which has no

The following description next to the drawing

  
 <EMI ID = 8.1>

  
understand how the invention can be realized, the particularities which emerge both from the drawing and from the text forming, of course, part of the said invention * Figure 1 is a schematic perspective view of the entire gear change and its controls Figure 2 shows, also in perspective but <EMI ID = 9.1>

 <EMI ID = 12.1>

  
In figure 1, we see that the variable speed drive <EMI ID = 13.1>

  
that brings together a belt 3, The variable pulley 1 is keyed on the shaft of the main motor 4, which drives the drum 5 of the machine through the speed variator

  
 <EMI ID = 14.1>

  
 <EMI ID = 15.1>. The movable flange of the variable pulley 1 can be driven in an axial translational movement required a stop 9, integral with a lever 10, so that the belt 3 is placed at the desired diameter. lever 10 <EMI ID = 16.1>

  
is driven by a linkage 12, itself actuated

  
 <EMI ID = 17.1>

  
 <EMI ID = 18.1>

  
A set of contacts 20, 21, 22, integral with

  
Output marble, through which the supply current of the small motor 16 passes, makes it possible to immobilize the cam 13 in the desired position.

  
In the present example, three speeds are provided to which correspond three positions of the control cam 13, namely the "washing" position shown in FIG. 2a (pulley 1 adjusted to the minimum effective diameter); there position "emptying" at intermediate speed '

  
 <EMI ID = 19.1>

  
shown in Figure 2c. By successively and separately feeding the son B, C and A, we obtain, in order, the emptying speed, the spin speed and the return to the washing speed. /

  
The contacts 20, 21 and 22 are controlled by a cam 23 and, if necessary, this cam can be arranged in such a way that an electrical locking occurs between the washing speed position and the washing speed position. onsorage, that is to say that it is

  
 <EMI ID = 20.1>

  
der the intermediate speed to reach the spin speed.

  
Of course, more than three speeds can be provided if this is deemed necessary.

  
Figure 3 shows in more detail the elastic linkage mechanism between the control motor unit 14 and the lever 10,

  
The lever 10, pulled by the spring 15 which is stretched by a certain amount, comes into abutment on a nut 24,

  
screwed onto the rod 12.

  
Nut 24 allows lever position adjustment
