Abstract: A method for operating a vehicle drive-train having a continuously power-branched transmission with secondary coupling. In the open operating condition of reversing clutches of a reversing gear unit, torque applied in the area of a drive output can be supported by a range group in the area of a variator. In the event of a command to interrupt the power flow between a drive engine and the drive output, it is checked whether the vehicle is on an inclined surface and if the result of that inquiry is positive, the power flow between the drive engine and the transmission is interrupted at the latest when the rotational speed of the drive output is reduced to zero by opening the reversing clutches, while the active connection between the drive output and the variator is maintained by way of the range group.

Abstract: An automated twin-clutch multi-speed transmission is disclosed for use in a four-wheel drive vehicle. The transmission includes a first engine clutch operable to establish a releasable drive connection between the engine and a first input shaft, a first motor/generator connected to the first input shaft, a second engine clutch operable to establish a releasable drive connection between the engine and a second input shaft, a second motor/generator connected to the second input shaft, a mainshaft, and a geartrain for selectively establishing a plurality of forward and reverse speed ratio drive connections between the input shafts and the mainshaft. The transmission further includes power-operated dog clutches for selectively engaging constant-mesh gearsets associated with the geartrain, and a transmission controller for controlling coordinated actuation of the first and second engine clutches, the first and second motor-generators, and the power-operated dog clutches to permit non-power interrupted (“powershift”) sequential gear changes automatically without input from the vehicle operator. An interaxle differential transfers drive torque from the mainshaft to the front and rear drivelines to establish a full-time four-wheel drive mode.

Abstract: In a driving apparatus for a four-wheel drive vehicle in accordance with the present invention, a multiple disc clutch is incorporated between a front wheel driving system and a rear wheel driving system, a hydraulic chamber is formed in a fixed casing supporting rotatably a front differential case in the front wheel driving system and a clutch piston is disposed in the hydraulic chamber. Bearings are disposed between the clutch piston and the front differential case in order to enable them to rotate relatively. Hydraulic pressure generated from hydraulic pressure generation means disposed outside each driving system is caused to act on the clutch piston so that the multiple disc clutch is operated by the press force of the clutch piston through the front differential case and the differential operation of the front and rear wheel is restricted in accordance with the operation force of the multiple disc clutch. Accordingly, the size in the radial direction can be reduced in the axial direction of the apparatus itself, and even if there is any limitation to the space, a large hydraulic pressure is permitted to act on the muliple disc clutch by forming only the small hydraulic chamber described above.

Abstract: A hydraulically-actuated starting clutch adapted for a continuously variable transmission which is located at the output of the transmission to couple the vehicle wheels to the engine upon a signal from the throttle induced system oil pressure. The clutch includes a cover connected to the drive shaft through a hub forming a pressure chamber behind a piston, a Belleville spring acted upon by a pressure disc extending between the spring and the piston and urging a pressure plate against the clutch plate and an end plate secured in the cover, and retractor fingers on said pressure disc engaging said pressure plate. A cooling oil impeller is positioned between the end plate and a clutch plate hub and operatively connected to the end plate, and the clutch plate is operatively connected to a sleeve shaft to drive the differential for the vehicle wheels. Also, a balance cap is operatively connected onto the hub to form a balance chamber in front of the piston to receive oil and compensate for the centrifugal effect of the oil in the pressure chamber behind the piston.

Abstract: A limited slip differential assembly includes a planetary gear assembly, a differential case, a differential gear assembly and a hydraulic clutch assembly. The differential case is coupled for rotation with a portion of the planetary gear assembly. The differential gear assembly is arranged within the differential case and includes a first side gear and a second side gear for coupling with first and second drive wheels of a vehicle, respectively. The hydraulic clutch assembly includes a clutch pack and a clutch actuator. Pressurized hydraulic fluid from a transmission pump is selectively provided to the clutch pack to actuate the clutch pack between an open configuration, in which the side gears rotate independently, and a fully closed configuration, in which the side gears rotate together such that the first and second drive wheels rotate at a same speed.

Abstract: A control apparatus for an automatic transmission includes a shift control section configured to perform a shift of the automatic transmission; and a judder judging section. The shift control section is configured to judge whether or not a progress of the shift is during an inertia phase. The judder judging section calculates a characteristic-gradient index value which is a value obtained by quantifying a phenomenon that appears as a relative rotational speed between input and output of the first friction-engagement element becomes reduced with a progress of the inertia phase. The phenomenon appears in a different way in dependence upon whether a relational characteristic of a friction coefficient of the first friction-engagement element with respect to the relative rotational speed is a positive-gradient characteristic or a negative-gradient characteristic. The judder judging section determines that the judder has occurred based on the characteristic-gradient index value.
