Abstract: An aluminum alloy brazing sheet including a core material, a sacrificial material provided on one surface of the core material, a brazing filler material provided on the other surface side of the core material, and an intermediate layer provided between the core material and the brazing filler material. The core material contains Si: 0.30 to 1.00 mass %, Mn: 0.50 to 2.00 mass %, Cu: 0.60 to 1.20 mass %, Mg: 0.05 to 0.80 mass %, and Al. The sacrificial material contains Si: 0.10 to 1.20 mass %, Zn: 2.00 to 7.00 mass %, Mn: 0.40 mass % or less, and Al. The intermediate layer contains Si: 0.05 to 1.20 mass %, Mn: 0.50 to 2.00 mass %, Cu: 0.10 to 1.20 mass %, and Al.

Abstract: The present invention is a vehicle traveling control device, which can extend the life of a structure constituting a vehicle body. For this purpose, the traveling control device includes respective pressure sensors (22) for detecting pressures exerted on suspensions, a vehicle speed detector (33), a controller (10) for obtaining stress exerted on at least one of a frame (1), a vessel (41), front axles (42), and a rear axle (43) based on pressure detection values from the respective pressure sensors (22) and for issuing a deceleration instruction when the obtained stress is greater than a predetermined allowable value, and a speed control means (31) for inputting the deceleration instruction and controlling at least one of an engine fuel injection quantity, a transmission, and a braking device so that a detected value from the vehicle speed detector (33) equals an instruction speed of the deceleration instruction.

Abstract: A suspension, for use on a construction machine, to provide excellent riding comfort, ease of operation, and stability, and a control method for controlling this suspension.
