<p>PURPOSE:To rapidly prevent the occurrence of racing through simple operation by slipping a shift clutch during shift operation and a direct coupling clutch during direct coupling operation in a state that the number of revolutions of an engine is maintained approximately at the same value during control of prevention of the occurrence of racing. CONSTITUTION:The crank shaft of a diesel engine 1 is connected to an input shaft 4 of a shift direct coupling clutch 3 located on the input side of a transmission 2. The shift direct coupling clutch 3 has a shift clutch 5 and a direct coupling clutch 6, an inner cylinder 7 on the input side of the shift clutch 5 is coupled to the input shaft 4, and an outer cylinder 8 on the output side to a torque converter 9. An outer cylinder 12 on the input side of the direct coupling clutch 6 is coupled to the input shaft 4 and an inner cylinder 13 on the output side to an input shaft 14 of a transmission 15. During the occurrence of racing of a drive wheel, an engine rotation speed is maintained at a specified value, and an oil pressure on the side where either the shift clutch 5 or the direct coupling clutch 6 is engaged is gradually decreased to exert a slip. After convergence of racing, a clutch is engaged, and control is made such that an engine speed is increased.</p> |
