摘要： A hydraulic vehicular transmission has a plurality of drive speed establishing devices (e.g. clutches) to be actuated for selecting a drive speed, and a pair of similar drive direction establishing devices to be actuated for selecting a drive direction. The drive establishing devices are all actuated and deactuated hydraulically by respective solenoid operated control valves via respective pilot operated valves. Since the solenoid valves are susceptible to malfunctioning, as in the event of trouble in the associated electrical circuitry, emergency control valves are interposed respectively between the solenoid valves and the pilot operated valves. Each emergency control valve is to be hand operated in the event of the malfunctioning of the associated solenoid valve for actuating or deactuating the associated speed or direction establishing device via the associated pilot operated valve. Additional features are incorporated for the greater utility of the transmission control system.

摘要： Provided is a device for performing speed change not leading to engine stall in a working vehicle such as a wheel loader while sustaining a required tractive force and reducing fuel consumption. When a speed (“forward”, “second speed”) suitable for a work is selected by a speed change operator, control means makes a modulation clutch engaged in response to the vehicle speed drop and makes a lock-up state where a lock-up clutch is engaged transit to a lock-up and modulation clutch slip state where the lock-up clutch is engaged while the modulation clutch slips. Subsequently, the control means performs a clutch control for causing a transition to both clutch slip state where the lock-up clutch and the modulation clutch slip in response to the vehicle speed drop, hence causing the transition to a torque converter operation state where the modulation clutch is engaged and the lock-up clutch is released.

摘要： A construction vehicle includes a control unit configured to shift gear after performing pre-shifting to couple a target speed-change gear that corresponds to a target speed with a target speed-change shaft in non-transmitting state of rotation of the input shaft when the gear shift is performed from a current speed to the target speed, in a state in which the current speed gear that corresponds to the current speed step and the current speed-change shaft that corresponds to the current speed gear are coupled. When the vehicle speed detected by the vehicle speed detecting section is zero, the control unit is configured to perform pre-shift auxiliary control prior to the pre-shifting control to input the rotation of the input shaft to the target speed-change shaft in a state in which the target speed-change shaft is not coupled to the plurality of speed-change gears.

摘要： A lubricating oil supply control device controls a lubricating oil supply amount to a transmission in a construction machine including a torque converter with a lock-up clutch. The lubricating oil supply control device includes a clutch state determining section, a lubricating oil amount detecting section and a lock-up clutch controlling section. The clutch state determining section determines whether or not the lock-up clutch is being coupled. The lubricating oil amount detecting section detects whether or not the lubricating oil supply amount to the transmission is short of a preliminarily set supply amount. The lock-up clutch controlling section decouples the lock-up clutch when the lock-up clutch is being coupled and the lubricating oil supply amount is short of the preliminarily set supply amount.

摘要： In a speed change gear system (1) in accordance with the present invention for changing between forward movement and rearward movement of a vehicle and for changing a speed of the vehicle by selectively fixing sun gears, carriers and ring gears of a plurality of epicyclic gear devices with respective mating clutches (8, 14, 24, 28), a brake (29) is connected to an output shaft (21) of this speed change gear system (1) to share energy absorption of the respective clutches, and the hydraulic pressure for the brake (29) is controlled in accordance with a rotation rate of the output shaft (21). Therefore, these clutches (8,14,18,24,28) can be small-sized. When the brake (29) is released, a quantity of lubrication oil being supplied is reduced, and therefore the stirring resistance of the lubrication oil can be reduced, and the transmission efficiency can be satisfactory.
