摘要： An engine torque, which corresponds to a target engine speed inputted in a controller, is determined by a functional computing function unit. A torque correction value is added to the engine torque, followed by the multiplication with a constant. The product is divided by a pump delivery pressure to determine a pump displacement. A target tilting corresponding to this value is determined by another functional computing function unit, and is then compared with another target tilting which has been determined from a negative control pressure. The smaller one is selected and is outputted as a target tilting. The torque correction value is set at an EEPROM through an input device as desired. Selection of a negative value as the torque correction value makes it possible to prevent occurrence of stalling.

摘要： An exhaust gas temperature raising processing system, which increases a load acting on an engine to raise the exhaust gas temperature, includes an electric assist motor connected to the engine and an inverter for adjusting a torque of the electric assist motor. It also includes a main controller having a first determination unit for determining whether or not an actuator control valve is in a non-feed state and a second determination unit for determining whether or not clogging has occurred on a filter of an exhaust gas purification system. When the non-feed state is determined by the first determination unit and clogging is determined to have occurred on the filter by the second determination unit, the main controller drives the electric assist motor to generate electric power such that a load acting on the engine is increased.

摘要： A hybrid construction machine has an electric motor for driving the swing structure, and the electric motor is prevented from becoming incapable of generating torque due to a low energy state or an overcharged state of an electricity storage device. A swing-mode selector switch 77 which is manually operated switches between a hydraulic/electric combined swing mode for driving the swing structure by driving both the electric motor and a hydraulic motor and a hydraulic solo swing mode for driving the swing structure by driving only the hydraulic motor. For a normal operation, the swing mode is initially set in the hydraulic/electric combined swing mode. For a specific operation, the operator switches the swing-mode selector switch from a hydraulic/electric combined swing position to a hydraulic solo swing position.

摘要： On the basis of reference torque and torque correction amount output units (T1 and T2), a torque control command pressure is calculated so that the input torques of first and second pumps are increased. The calculated torque command instruction pressure is then supplied as external command pressure to the varying mechanism of a regulator used for the first and second pumps so as to prevent the input torques of the first and second pumps from being decreased more than necessary. As a result, even when three variable displacement hydraulic pumps are used with the discharge pressure of one of the hydraulic pumps reduced by a pressure reducing valve and further the input torques of the other two hydraulic pumps are decreased by that pressure, the engine output can be efficiently utilized, and the work rate does not decrease.
摘要翻译：基于参考扭矩和扭矩校正量输出单元（T1和T2），计算转矩控制指令压力，使得第一和第二泵的输入转矩增加。然后将计算出的转矩指令指令压力作为外部指令压力提供给用于第一和第二泵的调节器的变化机构，以防止第一和第二泵的输入转矩减小到超过所需的压力。结果，即使使用三个可变排量液压泵，其中一个液压泵的排出压力由减压阀减小，另外两个液压泵的输入转矩也减小了该压力，发动机输出可以有效利用，工作率不降低。

摘要： In a toroidal type continuously variable transmission, a power roller bearing that serves as a thrust bearing includes an inner race composed of a part of a power roller, an outer race opposed to the inner race, and balls arranged for rolling motion between the outer and inner races. The power roller is in rolling contact with input and output disks and pressed thereby in a thrust direction. An end face of the inner race is formed having a first raceway groove having an arcuate cross section and in contact with the balls. An end face of the outer race is formed having a second raceway groove having an arcuate cross section and in contact with the balls. The second raceway groove is shallower than the first raceway groove, and the center of each of the balls is situated nearer to the inner race than a center position between the respective end faces of the outer and inner races is.
