Abstract

1468492 Positive detents; change-speed controls AUTOMOBILWERK EISENACH VEB 10 April 1975 [11 April 1974] 14735/75 Headings F2E and F2D Two components 6, 7 of an automatic transmission system are lockable by respective pawls K R , K P which are actuable by an acutating member 20 mounted on a longitudinally displaceable shaft 21 and slidable thereon in either longitudinal direction against springs 23; the member 20 is provided with two cam surfaces respectively operatively engageable with the pawls K P , K R upon displacement of the shaft 21 and a bushing 4 has regions 41, 42 to radially support the member 21 adjacent each of the pawls K P , K R . In the illustrated embodiment, the shaft 21 is movable with a setting lever 2 connected with a gear selector lever, and the pawls K P , K R are respectively moved into their locking positions when the lever 2 is moved into the extreme shift positions P, R. Members 6, 7 are respectively a reaction wheel 6 and a pawl crown 7.
