<p>A differential-locking positive clutch (3) for disabling a vehicle differential gearing (2) is operated by a brake-actuating device (4) for a vehicle-braking brake (1) through a connecting mechanism (34) including a spring (6). The spring may store an actuating force for a clutch-operating member (5), which is preferably composed of a slidable shaft, when interlockable members of the clutch are not in alignment with each other. The connecting mechanism preferably includes a movable first engaging member (7) which is engaged to the clutch-operating member such that a movable second engaging member (48) operated by a clutch-operating device (45) may also be engaged to the clutch-operating member so as to permit an operation of the locking clutch independently of the brake. Both of a safe stopping of vehicle at its straight travel condition and a reduction of the vehicle braking distance are successfully attained.</p> |
