摘要： A speed change mechanism (1) constructed by connecting in tandem a hydraulic type speed change unit (17) having a plurality of hydraulic clutches (57, 58, 59) to be alternatively engaged and a hydraulic type speed change unit (20) having a plurality of hydraulic clutches (66, 67, 68) to be alternatively engaged, wherein a time-varying region (common slip region) is secured in which the two clutches slip in common such that during speed change, when the working hydraulic pressure in a clutch to be engaged is on its way to gradual increase, the working hydraulic pressure in a clutch to be disengaged lowers. This common slip region is made smaller during shift-down than during shift-up by a change in time-difference between the pressure increase start time for the clutch to be engaged and the pressure decrease start time for the clutch to be disengaged or by a change in the pressure decrease property of the clutch to be disengaged, and is maintained constant irrespective of whether one or two hydraulic clutches are engaged and disengaged during speed change respectively or irrespective of a difference in engine rpm.

摘要： An engine stall prevention control method for construction machines for automatically preventing engine stalls without complicated inching pedal operations to thereby prevent the operator from being exhausted, comprising a transmission (10) in which forward and reverse clutches (40, 32) that are located at the first step from an input shaft (13) are selectively brought into engagement to perform shifting between forward and reverse gears and a plurality of speed-change clutches (66, 68, 74) that are located at the second step from the input shaft (13) are selectively brought into engagement to perform shifting between speed gears, and respective electronically controlled modulating valves (107-111) for generating hydraulic pressures corresponding to electric commands from a transmission controller (131) at the respective clutches, said method being characterized in that an engine stall prevention control zone (P) and an engine stall prevention control releasing zone (Q) are set by an engine speed and a differentiated value of the engine speed, whereby when those engine speed and differentiated value of the engine speed fall within the control zone (P), the hydraulic pressure of said engaged clutch is reduced, while when falling within the release zone (Q), the hydraulic pressure of the engaged clutch is increased.

摘要： An electronic pressure control valve (40) is connected to a lockup clutch (4) directly connected to input/output shafts (1a, 2a) of a torque converter (2). In order to change the speed, the lockup clutch (4) is disconnected when the filling of transmission clutches (21-24) to be engaged next has been finished, to prevent the nonavailability of torque. With respect to the lockup clutch (4) in which an inner pressure (Pt) of the torque converter is applied to a back pressure portion of a piston, the inner pressure of the torque converter (2) is applied to the side of a proportional solenoid (42) of the pressure control valve (40), to enable an initial pressure to decrease. During a speed changing operation, the lockup clutch (4) is not completely disconnected to maintain the low pressure, whereby a shock due to the lockup clutch shifting operation is lessened. In order to gradually increase the hydraulic pressure, a degree of opening of a throttle, the weight of the vehicle and a gear ratio are determined, and a rate of gradual increase is varied in accordance with these values. In order to drive the vehicle at a regular speed, the hydraulic pressure in the lockup clutch is controlled so that it is in the vicinity of the level of the engine output torque, to thereby widen the region of travelling with the lockup clutch used.

摘要： This invention relates to a method and apparatus for controlling a structure in which electronic pressure control valves (21-24) are connected separately to the clutches (H, L, 1st, 2nd) in a transmission having a two-step clutch system consisting of main speed change gears (1st, 2nd) and auxiliary speed change gears (H, L) to enable each clutch to be controlled independently. In the case where a discharge rate of a pump at the time of starting the engine is not sufficiently high with both auxiliary clutches and main clutches required to be engaged, the speed change is done by supplying a hydraulic pressure at staggered time to the clutches (H, L) in the main speed change gear and the clutches (1st, 2nd) in the auxiliary speed change gear so that the supply of a hydraulic pressure to the main clutches is started after the filling of the auxiliary clutches has been completed, whereby variations in the filling time, which is ascribed to a decrease in the discharge rate of the pump, are minimized.

摘要： A hydraulic control system includes a linear solenoid valve, an ON-OFF solenoid valve and a hydraulically-operated frictional engagement device. A first hydraulic pressure is regulated by the linear solenoid valve within a predetermined pressure-regulation control range, and is supplied to the frictional engagement device. In a state in which the frictional engagement device is placed in a predetermined engaged state based on the first hydraulic pressure, a second hydraulic pressure, which is higher than the pressure-regulation control range, is supplied from the ON-OFF solenoid valve to the frictional engagement device, such that the frictional engagement device is placed in a fully engaged state with a high engaging torque based on the second hydraulic pressure.
