摘要： A transmission comprising an input shaft connectable to a power generation device such that the input shaft is rotatable at a power input rotational speed, an output shaft connectable to a driveline of the vehicle, and a plurality of gear sets selectable to operably connect the input shaft to the output shaft providing a rotational speed reduction ratio therebetween. The gear sets comprise a master active gear set having a master gear ratio, a slave active gear set having a slave gear ratio, and a passive gear set having a passive gear ratio. The passive gear set is operable to selectively engage the master and slave active gear sets to provide the high numeric compound ratio rotational speed reduction that is the product of the master active gear ratio, the slave active gear ratio and the passive gear ratio.

摘要： Variable motion control devices and methods of use. The devices and methods relate to providing an output, such as a rotational shaft output, transmitted from a rotational shaft input, with the output varying based on a control input. The devices and methods are used, for example, to provide a variable output for use with a compressor, power take off, or transmission or differential application. To provide the variable output, the devices and methods include use of mechanical component systems, such as spur gear planetary systems, ring gear planetary systems, bevel gear arrangements, or combinations of such features. The control input is implemented, for example, by arrangements of bindably meshed gears, tension between pulleys joined by belts or similar arrangements of sprockets and chains, use of magnetic clutches, hydraulic or pneumatic controls, or braking devices.

摘要： An oil pressure control device, which changes a range of a vehicle transmission includes: a pressure adjusting device that engages or releases forward and reverse frictional-engagement devices by adjusting an oil pressure supply, a sensor that detects a range selected by a vehicle driver, and a controller that controls the clutch pressure adjusting device based on a signal from the sensor. When the stop range is selected after selecting the reverse (forward) range, a forward (reverse) range is selected. After supplying an initial oil pressure to the forward (reverse) frictional-engagement device, the pressure adjusting device is controlled so that the pressure decreases from the initial oil pressure to a predetermined oil pressure. Subsequently, the oil pressure is initially increased at a small increase rate from the predetermined oil pressure. After a predetermined time period has elapsed, the pressure adjusting device increases the oil pressure at a large increase rate.
