Title: Disque d’embrayage avec dispositif a roue libre comprenant deux systemes de rampes
Inventor: FINKENZELLER MARC
IPC: F16D13/64
Filed: 2023-04-20
Abstract: Le disque d’embrayage 2 décrit dans la présente description comporte un dispositif à roue libre 8 disposé radialement à l’intérieur avec deux systèmes de rampes 13, 15 pouvant tourner l’un par rapport à l’autre, la rotation du premier système de rampes 13 entraînant au moyen d’une roue libre de commande 22 un décalage axial du second système de rampes 15, qui entraîne un déplacement axial des disques extérieurs 7 et des disques intérieurs 12 dans la direction d’actionnement 21, de sorte qu’en régime de frein moteur, un couple puisse être transmis entre la garniture de friction 3 et le moyeu 10 par l’intermédiaire du bloc de disques. Lorsque la roue libre de commande 22 interrompt, en régime de décélération, la transmission de couple, le dispositif à ressort 19 entraîne le retour en arrière des systèmes de rampes 13, 15, et la liaison par friction dans le bloc de disques est libérée. La transmission de couple par l’intermédiaire des disques intérieurs 12 et des disques extérieurs 7 est ainsi interrompue, de sorte que lorsque l’embrayage est embrayé, un mode roue libre puisse être mis en œuvre, le moteur à combustion interne 202, accouplé à la garniture de friction 3, pouvant tourner indépendamment de l’arbre d’entrée de boîte de vitesse 203, accouplé au moyeu 10.

Title: Advancing mechanism for strip - has variable amplitude advancing motion
IPC: B21D43/10
Filed: 1971-10-14
Abstract: Appts. for inducing an advancing motion is sufficiently variable amplitude to a band of material, e.g a steel strip (straightened or not) in the work direction using a conveyor with grips. The rectilinear advancing motion of the band produced by a carrier of the grip conveyor is converted by devices into a (partially) circular motion to be transmitted to a second carrier which is part of the advancing mechanism. The transformation of rectilinear forward motion into circular motion is accomplished by an articulated rod which has its free end kinetically linked to the advance mechanism by an eccentric plate which can be regulated. Advantages include greater simplicity and more ontrol. The amplitude is directly proportional to the forward motion of the grips.
