Setting in motion, in particular to an agricultural tractor, and thus relates to the tractor

摘要

P the movement comprises an input shaft 11 coupled to the motor of the tractor, and an output shaft 17. Between the two shafts 11, 17, are mounted a clutch 16 to the hydraulic control, and a reducing gear 10 to 13, 14, associated with the clutch 16. The casing of the reducing adapter 10 contains the oil which may be sucked in by a hydraulic pump 18, rotating with the input shaft 11. The pump 18 delivers the oil under pressure through a pipe 20, leading to a member 19 for controlling the clutch. A calibrated discharge valve 21 ensures the return of the oil to the casing of the reduction gear 20. A solenoid valve of the branch 23 makes it possible to the short - circuited the discharge valve 21, to reduce the oil pressure in the pipe 20. / p & & p & application to the movement, in particular to agricultural tractors. / p
