ABSTRACT:
A rotating assembly (10) is associated with transmission and parking brake components (33,34) of a work vehicle or arbor and chuck components of a machine tool operation. The use of one component during operation of the other component can result in damage to the components. The rotating assembly (10) has a first member (12) and a second annular member (14). Rotation of each member (12,14) is associated with operation of a respective component, such as shifting the transmission (33) or applying or releasing the brake (34). Apparatus (38) maintains one of the first member (12) and second annular member (14) against rotation and frees the other of the members (14,12) for rotation at respective positions (40,42) of the apparatus (38) for selectivey interlocking the first member (12) relative to the second member (14). This prevents application of the brake (34) if the transmission (33) is not in neutral and prevents shifting of the transmission (33) from neutral before the brake ( 34) is released.
