Title (EN) AXIAL ROTARY EDDY CURRENT BRAKE WITH ADJUSTABLE BRAKING FORCE
(FR) FREIN MAGNETIQUE ROTATIF AXIAL PRESENTANT UNE FORCE DE FREINAGE REGLABLE
Abstract:
(EN) The present invention relates to an axial adjustable, rotary brake device using eddy current resistance, having an annular rotating conductive reaction member fastened on a central axle, having a frame, and fitted with permanent magnets disposed on either one side or both sides of said member, wherein the magnets produce a magnetic field between the magnet arrays, and through the member. Relative motion of the member and magnets produces eddy current resistance opposing the movement of the member. The magnets are mounted such that their respective positions relative to each other and thus to the intermediate conductive member can be changed by an adjusting Structure to increase or decrease the space between magnets and member, (air gap), distance from the rotational center or their relationship to each other. Various other configurations for changing the spatial relationship of magnets and members are presented which can be employed to produce many embodiments and variations of the present invention.
(FR) La présente invention concerne un dispositif de freinage axial rotatif, réglable, qui utilise une résistance aux courants de Foucault, présente un élément de réaction conducteur rotatif annulaire fixé sur un essieu central; comprend un châssis et est équipé d'aimants permanents disposés sur un ou les deux côtés de l'élément, lesquels aimants produisent un champ magnétique entre les réseaux d'aimants et à travers l'élément. Un mouvement relatif de l'élément et des aimants produit une résistance aux courants de Foucault qui s'oppose au mouvement de l'élément. Les aimants sont montés de sorte que leurs positions respectives les uns relativement aux autres et relativement à l'élément conducteur intermédiaire puissent être changées par une structure de réglage pour augmenter ou diminuer l'espace entre les aimants et l'élément (distance d'éclatement), la distance depuis le centre de rotation, ou leur relation les uns vis-à-vis des autres. Diverses autres configurations destinées à changer la relation spatiale des aimants et des éléments sont décrites, qui peuvent être mises en oeuvre pour produire plusieurs modes de réalisation et variantes de l'invention.
