    摘要： A system for transmitting power from an engine shaft to a power take-off (PTO) shaft of a utility vehicle, comprising a transmission (3) having an input shaft (3a) coupled to the engine shaft and an output (3b, 3c) driveably connectable to one or more driven axles (4, 5) of the vehicle. A synchronised shift device (7) is operable to selectively connect an output shaft (7a) thereof to one of the transmission input shaft and output, said output shaft (7a) further being driveably connectable to the PTO shaft (10). The synchronised shift device (7) comprises inner and outer coaxially aligned and respectively rotatable input bodies alternately connectable to the shift device output shaft (7a), with the inner input body connected to the transmission input shaft (3a) and the outer input body driveably connected to the transmission output (3b, 3c). The arrangement provides switching between engine speed and ground speed operation of the PTO.

    摘要： A control device of a four-wheel-drive vehicle having an electronic control coupling (92L, 92R) changing a transmission torque, and a connecting/disconnecting mechanism (32) connecting/disconnecting an input to the input-side rotating member of the coupling, the control device (78) comprises: a storage portion (180a, 182a) storing a relationship between the drive current to the coupling and the transmission torque of the coupling; a control portion (180, 182) controlling the drive current based on the relationship; and a learning portion (180b, 182b) performing correction for the relationship through learning by applying a braking torque to the input-side rotating member by an electromagnetic actuator (128). The learning portion performs the correction for the relationship by using the drive current supplied to the coupling and the braking torque at the time of determination that the transmission torque is balanced with the braking torque based on rotational speeds of the input-side rotating member and the output-side rotating member while the rotational speed of the input-side rotating member is increased.

    摘要： The invention relates to a connecting device of a vehicle drive train, outside a variable-speed transmission, for the rotary coupling of a vehicle shaft (12) and of a vehicle drive train element (13) which is rotatable relative thereto, having a sliding sleeve (10) which is arranged non-rotatably and axially displaceably between at least one first and second position on the vehicle shaft (12), wherein, in the first position, the sliding sleeve (10) brings about rotary decoupling of the vehicle shaft (12) from the vehicle drive train element (13) and, in the second position, brings about the rotary coupling thereof, and having actuating means (16, 17, 18) for displacing the sliding sleeve (10) between the first and second position, with at least one shift groove (16, 17) along a circumference of the sliding sleeve (10), and engagement means (18) for engaging in the shift groove (16, 17). According to the invention, the sliding sleeve (10) is moveable rotatably and axially with respect to the engagement means (18), wherein the shift groove (16, 17) is designed in the form of a radial cam such that, when the engagement means (18) engage in the shift groove (16, 17) and when the sliding sleeve (10) rotates with respect to the engagement means (18), the sliding sleeve (10) is moved axially by the shift groove (16, 17) between the first and second position.
