Abstract
An assembly (10) for connection between a steering wheel (12) and a steerable member (14) includes a clutch mechanism (28) operatively connected to the steering wheel (12) and a drive mechanism (30) connected between the clutch mechanism (28) and a push pull cable (22). The push pull cable (22) is in turn connected to the steerable member (14). The clutch mechanism (28) prevents torsional forces from the steerable member (14) to be transmitted to the steering wheel (12). The clutch mechanism (28) includes a driving dog (38) connected to the steering wheel shaft (18) and a pinion member (40) connected to the drive mechanism (30). The driving dog (38) includes three radially extending legs (44, 45, 46) and the pinion member (40) includes arcuate arms (64, 65, 66) extending therebetween. Rollers (84-89) are biased by springs (96-98) to be wedged between the arms (64, 65, 66) and housing (32), and are released only upon rotation of the legs (44, 45, 46).
