IPC: B60K11/04
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To reduce noises that leak behind a working vehicle during normal driving and to prevent overheating of the engine during high-load driving. SOLUTION: A louver mechanism 17 provided at an exhaust port changes the area of an opening between louvers 18 by changing the angles of the louvers 18 using a stepping motor 20. When the temperature of radiator water detected by a water temperature gauge 14 and the temperatures of operating oil for a working vehicle and operating oil for a travel unit, detected by respective oil temperature gauges 15, 16, are all not higher than respective set temperatures, a control unit controls the stepping motor 20 to increase the angles of the louvers 18 to point them upward. If either one of the temperatures of the radiator water, the operating oil for the working vehicle and the operating oil for the travel device exceeds its set temperature, the stepping motor 20 is controlled so that the angles of the louvers 18 are changed to orient them in the horizontal direction.
