摘要： A shift control system of a toroidal CVT for a vehicle is arranged to calculate a command gear ratio by adding a desired gear ratio and a torque shift compensation quantity for compensating a difference between the desired gear ratio and an actual gear ratio which difference is generated by a shifting operation of the toroidal CVT, and to set a magnitude of the torque shift compensation quantity employed in an automatic shift range to be larger than a magnitude of the torque shift compensation quantity employed in other shift range except for the automatic shift range when the actual gear ratio is in a first gear ratio region except for a second gear ratio region including a largest gear ratio.

摘要： A hydraulic control device operates a sliding selector shaft, in particular a gearbox for motor vehicles, with a bore made in a wall of a gearbox housing for accommodating a plastic piston. The piston is actively connected to the sliding selector shaft and delimits a pressure chamber and, under hydraulic pressure, radially guides and axially displaces the sliding selector shaft. The piston has a body and a guide section consisting of plastic. The piston is guided directly at the bore, designed as a non-reinforced and unlined cylinder bore, in the wall of the gearbox housing, consisting of a light metal alloy. This creates control device, which is of a much simpler, and more compact design compared with prior art.

摘要： In a toroidal continuously variable transmission, a secondary oil pump is provided in addition to a primary oil pump driven by an engine. The secondary oil pump is driven in response to rotation of a road wheel. A hydraulic servo mechanism is connected to a trunnion to create an offset of the power roller from a neutral position for a tilting motion of the power roller. A feedback device is provided for feeding a degree of progress for ratio changing back to the hydraulic servo mechanism so that the power roller returns to the neutral position when a desired transmission ratio has been reached. When the road wheel is rotated in a stopped state of the engine, hydraulic pressure from the secondary oil pump is supplied to the hydraulic servo mechanism so that an actual transmission ratio is brought closer to a desired transmission ratio.

摘要： An adaptive electronic transmission control for an automatic transmission having multiple-ratio gearing establishing plural torque flow paths between a torque input member and a driven member, the relative motion of the elements of the gearing being controlled by a friction torque establishing member and an overrunning coupling connection between two gear elements of the gearing. A ratio shift is achieved by establishing a driving connection between a selected gearing element and a torque delivery shaft. The shift is achieved by controlling the capacity of the friction element using a fluid pressure actuator. Shift quality is optimized by establishing a bias pressure on a friction element accumulator and by using a feedback control system to control the rate of change of transmission ratio during the shift.
