摘要： A gearshift controller for an industrial vehicle, includes: a speed ratio detection unit that detects a speed ratio of speeds of an input axis and of an output axis of a torque converter; a gearshift control unit that shifts up a speed stage when the detected speed ratio is equal to or more than a first predetermined value and shifts down the speed stage when the detected speed ratio is equal to or less than a second predetermined value, which is smaller than the first predetermined value; and an operation member with which a downshift to the first speed is instructed by operation thereof by an operator. When the downshift is instructed by the operation member, the gearshift control unit controls the speed stage to be kept at the first speed for a predetermined time period regardless of the speed ratio detected by the speed ratio detection unit.

摘要： A method of operating a hydraulic pump of a drive train of a motor vehicle having a transmission with a hydrodynamic torque converter and a engine, with the input speed of the hydraulic pump being adjusted depending on the speed of the engine. The input speed of the hydraulic pump is adjusted depending on the pump speed of the torque converter, which corresponds to the speed of the engine and depends on the turbine speed of the torque converter, such that when the pump speed of the torque converter is higher than the turbine speed of the same, the hydraulic pump is operated at a speed higher than the speed of the engine. When the turbine speed of the torque converter and the pump speed of the same equalize, the excessive increase in the input speed of the hydraulic pump is reduced in relation to the speed of the engine.

摘要： A transmission assembly is disclosed. The transmission assembly includes a continuously variable transmission driven by an input shaft at an input speed, a mechanical transmission coupled to the continuously variable transmission for selecting a first gear range and a second gear range, an output shaft driven by the mechanical transmission at an output speed, and controller operable to receive a speed command and generate a transmission ratio is command which control a ratio of the output speed to the input speed, and generate a shift command which causes the mechanical transmission to shift from the first gear range to the second gear range. An upper transmission ratio limit defined by an engine lug limit. A lower transmission ratio limit is defined by an engine overspeed limit. The controller causes the transmission to execute a shift from the first gear range to the second gear range which causes an instantaneous change in output speed. The engine lug limit or the engine overspeed limit are adjusted to inhibit a subsequent shift from the second gear range to the first gear range. A method for controlling a transmission assembly is also disclosed.

摘要： A method of power transmission in a mechanical/hydraulic type transmission system, by which changeover is smoothly effected between hydraulic power transmission and mechanical power transmission is provided. To this end, there are provided a hydraulic power transmitting means, for transmitting a mechanical power (Pm), which has been converted by a hydraulic motor (42), to the outside (300) by the engagement of a clutch (A), and a mechanical power transmitting means for transmitting a mechanical power (Po) to the outside (300) by the engagement of a clutch (B). Upon changeover from hydraulic power transmission to mechanical power transmission, the releasing of the clutch (A) is performed after the engagement of the clutch (B) is started and before the engagement of the clutch (B) is completed.

摘要： An automatic transmission includes a multi-speed transmission gear mechanism having an input shaft, an output shaft and a plurality of friction coupling elements. A hydraulic control system selectively supplies a hydraulic pressure to the friction coupling elements, thereby selectively applying the friction coupling elements to cause the transmission gear mechanism to shift to a speed which is determined according to a predetermined shift pattern. The control system sets a target hydraulic pressure to be applied to the friction coupling elements according to the kind of the shift to be effected and the engine load, and, when it is detected that the transmission gear mechanism is to make a backout upshift due to reduction in the engine load, increases the target hydraulic pressure by an amount which is determined according to the throttle opening and the turbine speed.
