摘要： A continuously variable transmission unit, which combines a toroidal-type continuously variable transmission of the double-cavity type and an epicyclic train, comprises a low-speed clutch and a high-speed clutch. In a low-speed drive mode, the low-speed clutch is connected to allow all torque to be transmitted to an output shaft through the toroidal-type continuously variable transmission. In a high-speed drive mode, the high-speed clutch is connected to allow most of torque to be transmitted to the output shaft through an epicyclic train and some of the torque to be applied to output discs of the toroidal-type transmission. The combination of the transmission and the epicyclic train serve to improve the transfer efficiency and durability of the continuously variable transmission unit.

摘要： Improved input and output discs for toroidal type continuously variable transmissions are obtained by select processing techniques to form hardened layers. Processing techniques include, e.g., carburizing, carbonitriding, and high-frequency induction hardening. Shot peening may be used to impart compressive residual surface stress to predetermined disc portions to enhance resistance to cracking.

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 purification system for an engineering machine is capable of avoiding decreases in working efficiency during regeneration control by burning off a deposit of particulate matter from a filter efficiently during a work pause time. An operating section 17 of a display monitor 16 is used to set a work pause time and a work pause switch 13 notifies a vehicle body control unit 21 that the hydraulic excavator has entered a work pause state. In response, the vehicle body control unit 21 calculates the time required for a regenerating device to burn off the current amount of particulate matter deposited on the filter, and when the calculated time is longer than the preset work pause time, a regeneration controller 4a of an engine control unit 4 is activated, and a solenoid control valve 15 is switched to a closed position during the preset work pause time.
