Abstract

Se describe una transmision que emplea un selector de velocidades de tipo tambor teniendo "pads" o almohadillas circunferenciales que utilizan geometría de almohadilla de transmision, que permite que una almohadilla esté en contacto completo en el tambor. Cada almohadilla tiene su centro de gravedad "Cg" sobre la parte izquierda del punto de pivote de manera que la fuerza centrífuga de la almohadilla "Cf" mantiene a la almohadilla fuera de contacto en el tambor cuando rota en neutro. Un resorte tiene uno de sus extremos enganchado a una ranura de la almohadilla y su otro extremo está fijo en un punto; también descansa sobre el muelle hidráulico en otro punto. La disposicion del muelle y su forma permite al resorte actuar en dos direcciones mayores requeridas para la operacion apropiada de la almohadilla. Una accion es halar la almohadilla alrededor de su punto de pivote a la posicion neutra al rotar la almohadilla alrededor del pivote una determinada distancia. Al mismo tiempo, cuando la almohadilla es halada a la posicion neutra, el muelle hidráulico es rotado alrededor de su punto de pivote a la posicion contra el resorte. Estos dos movimientos ubican a la almohadilla en su posicion de descanso con ciertos intervalos de luz detrás y al frente de la almohadilla. Debe destacarse que la fuerza centrífuga "Cf" es una fuerza mayor, que mantiene a las almohadillas en una posicion neutra cuando los engranajes están en modo de operacion libre.A transmission is described that employs a drum-type speed selector having "pads" or circumferential pads that use transmission pad geometry, which allows a pad to be in full contact in the drum. Each pad has its center of gravity "Cg" on the left side of the pivot point so that the centrifugal force of the pad "Cf" keeps the pad out of contact in the drum when it rotates in neutral. A spring has one of its ends hooked to a groove in the pad and its other end is fixed at one point; It also rests on the hydraulic spring at another point. The arrangement of the spring and its shape allows the spring to act in two major directions required for the proper operation of the pad. One action is to pull the pad around its pivot point to the neutral position by rotating the pad around the pivot a certain distance. At the same time, when the pad is pulled to the neutral position, the hydraulic spring is rotated around its pivot point to the position against the spring. These two movements place the pad in its resting position with certain intervals of light behind and in front of the pad. It should be noted that the centrifugal force "Cf" is a major force, which keeps the pads in a neutral position when the gears are in free operation mode.
