<p>A park-lock device (1) comprising a first arm (3) arranged on a shift actuating device (22) to move with at least a portion of the shift actuating device (22) between at least a first position and a second position, a bracket member (9) movable between at least a first position and a second position wherein the bracket member (9) is adapted to actuate an engagement device (17) to prevent rotation of a transmission output shaft (21) in the second position, wherein the first arm (3) and the bracket member (9) is mechanically interconnected via a spring member (8), wherein when the first arm (3) is in the first position the spring member (8) is in a first position wherein the bracket member (9) remains in a first position, wherein when the first arm (3) is in a second position, the spring member (8) is in a second position of higher potential spring energy than in the first position, wherein the spring member is biased to move the bracket member (9) towards the second position, wherein the park-lock device(1) further comprises an electrically actuated locking device (13) comprising a movable locking member (13a) adapted to be releasably engaged with the bracket member (9), wherein when the movable locking member (13a) is in a first position, it prevents movement of the bracket member (9) from a first position to a second position, wherein when the movable locking member (13a) is in a second position upon actuation of the park-lock device 1, the bracket member (9) is allowed to move from the first position to the second position, whereby the engagement device (17) is actuated to prevent rotation of the transmission output shaft (21).</p> |
