CONJUNTO DE ALAVANCA DE COMANDO DE MODALIDADE MULTIPLA

A lever is integral with a rotatable hub (40). A brake lever (70) pivoted on a pivot (16) is biased by a spring (76) to urge a brake show (74) against part of the hub (40). A detent lever (80) pivoted on the same pivot (16) is biased by a spring (88) to engage a detent roller (84) with a sector of t...

Zusammenfassung:	A lever is integral with a rotatable hub (40). A brake lever (70) pivoted on a pivot (16) is biased by a spring (76) to urge a brake show (74) against part of the hub (40). A detent lever (80) pivoted on the same pivot (16) is biased by a spring (88) to engage a detent roller (84) with a sector of the hub containing detent notches (62, 64). A centering spring biases the lever hub (40) to the illustrated, neutral position. A rotary cam (26) acts on cam followers (72, 82) on the brake lever (70) and detent lever (80) to disengage both brake and detent in the position shown. The cam is rotatable to other positions by a solenoid (90) pawl (92) and ratchet wheel (36), one position allowing the brake to engage (establishing a friction-held mode for the lever) and another position allowing the detent to engage, providing for detent holding of the lever in its spring centred mode.
