摘要： PROBLEM TO BE SOLVED: To enable a lockup state in a low-speed region and prevent a shortage in the amount of lubricant for a transmission due to this.
SOLUTION: The control device, which is a device for controlling the amount of the transmission lubricant for a construction machine having a torque converter with a lockup clutch, comprises a clutch state determination means, a lubricant amount detection means and a lockup clutch control means. The clutch state determination means determines whether a lockup clutch 7 is in a connection state or not. The lubricant amount detection means detects whether the supply amount of the lubricant to a transmission 2 is short for a preset supply amount or not. The lockup clutch control means causes the lockup clutch 7 to be put in a disconnection state when the lockup clutch 7 is in a connection state and the supply amount of the lubricant is short for a preset supply amount.

摘要： PROBLEM TO BE SOLVED: To provide a construction vehicle capable of quickly switching shift stage even in such a state that the vehicle is stopped. SOLUTION: In the construction vehicle of this invention, when switching the shift stage from a current speed stage to a target speed stage, a control part switches the shift stage after conducting pre-shift for engaging a target shift shaft in which rotation transmission with an input shaft is disabled and a target shift stage gear corresponding to the target speed stage while a current shift stage gear corresponding to a current speed stage and a current shift shaft corresponding to the current shift stage gear are engaged and rotation transmission between the input shaft and the current shift shaft is enabled. The control part conducts the pre-shift after executing a pre-shift auxiliary control for inputting rotation of the input shaft to a target shift shaft while the target shift shaft and the plurality of shift stage gears are not engaged in the case in which a vehicle speed detected by a vehicular speed detection part is zero.

摘要： PROBLEM TO BE SOLVED: To further reduce fuel consumption while maintaining while maintaining a required tractive force, and to carry out speed change not leading to engine stall in a working vehicle such as a wheel loader. SOLUTION: When a speed ("drive", "second speed") suitable for work is selected by a speed change operator 70, a control means 80 makes a modulation clutch 20 engaged in response to the vehicle speed V drop, and makes a lock-up state where a lock-up clutch 40 is engaged to transit to a lock-up and modulation clutch slip state where the lock-up clutch is engaged and the modulation clutch is slipping. Subsequently, the control means causes transition to a both clutch slip state where the lock-up clutch and the modulation clutch are slipping in response to the vehicle speed V drop.
