Abstract

EN UN DISPOSITIVO HABITUAL DE ESTE TIPO SE CIERRA UN CONTACTO ELECTRICO, CUANDO UN ELEMENTO ELASTICO ELASTOMERO PERTENECIENTE A UNA COPLAMIENTO DE LANZA, SE INSTALA, BAJO LA INFLUENCIA DE UNA FUERZA AXIAL EN UNA MEDIDA PREDETERMINADA O POR ENCIMA DE LA MISMA. EL DISPOSITIVO ANUNCIA SOLO, POR TANTO, LA FUERZA AXIAL EJERCIDA HACIA ARRIBA DE UNA DETERMINADA MAGNITUD DE EMPLEO. EN LOS CASOS DE EMPLEO, EN LOS QUE SE LLEGA AL VOLUMEN DE LA FUERZA AXIAL, ESTE DISPOSITIVO NO RESULTA APROPIADO. PARA ELIMINAR ESTA DESVENTAJA, LA PATENTE SE PROPONE ENCAUZAR LA MENCIONADA PRESION DE LA FUERZA AXIAL EN EL ELEMENTO ELASTICO ELASTOMERO Y COLOCAR UN SENSOR DE PRESION (2,18 O 7), ENTRE EL ELEMENTO ELASTICO ELASTOMERO (5 O 16) Y LA CAJA (PIEZA DE SOPORTE 3 O 9) O LA BARRA DE TRACCION (6, 22) DEL ACOPLAMIENTO. OTRA POSIBILIDAD ES QUE EL SENSOR DE PRESION (10) SE COLOQUE EN EL ELEMENTO ELASTICO ELASTOMERO (5, 16). EL TERRENO PREFERIBLE DE UTILIZACION ES LA TECNICA DEL AUTOMOVIL.
