<p>The invention concerns an arrangement for the actuation of a parking brake o f a vehicle, particularly that of an agricultural or industrial utility vehicle. The arrangement includes an actuating mechanism (12) and an actuator (14). The actuating mechanism (1 2) can be forced into an engaged position by means of a preload. A movement of the actuating mechanism (12) can be performed against the force of the preload by means of the actuator (14). The actuating mechanism (12) includes a parking brake blocking arm (16 ) supported in bearings, free to rotate about an axis (22), that engages in a lock , whe n it is in an engaged position, in a component (26) supported in bearings, free to rotate. Moreover the present invention concerns an agricultural or industrial utility vehicle wit h a parking brake (io). In order to permit an actuation of the parking brake (io) with relatively low force even with high loads upon the components of the parking brake (io) and in order t o reduce the requirements upon the tolerances of the components of the parking brake (io) , the actuating mechanism (12) is provided with a toggle joint configuration (4o).The toggle joint configuration (40) and the parking brake blocking arm (16) interact with eac h other in such a way that the movement of the parking brakeblocking arm (16) and the toggle joint configuration (40) can be performed as a function of the actuation of the actuator (14).</p> |
