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： 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.
