PROBLEM TO BE SOLVED: To provide a transmission capable of easily storing a driving member of a front wheel in one gear case and small in longitudinal dimension. SOLUTION: A front wheel output shaft 34 is arranged to be in parallel with a second input shaft 21 linked to an engine on the same axis, the rotation of the second input shaft 21 is transmitted to an intermediate output shaft 28 arranged below the input shaft through a transmission clutch 23 and a plurality of gears 27, 30 linked to the clutch, a front wheel driving gear 35 of the front wheel output shaft 34 and a rear wheel driving gear 33 of a rear wheel output shaft 32 arranged below the intermediate output shaft 28 are engaged with the intermediate output gear 29 of the intermediate output shaft 28, and these members are stored in one gear case 13.

Transmission of vehicle with grader

PURPOSE:To reduce a cost by detecting engine speed of front and rear wheels with a simple speed detector, and controlling oil pressure supplied to a grader blade controlling cylinder based on a revolving speed difference calculated with a controller. CONSTITUTION:In the case snow is to be removed with a grader blade 30, a differential lock mechanism 88 of a distribution machine 54 is in an unlocking state, and differential of output of the front and rear wheels is in an allowable state. After that, speed signals of a front wheel speed detector 154 and a rear wheel speed detector 156 provided respectively to front and rear wheels are supplied to a second controller 48. Then, the controller 48 detects slip ratio in comparison with speed signals of the detectors 154 and 156. A signal of the slip ratio is supplied to a hydraulic adjusting device 34, and hydraulic pressure oil supplied to a hydrulic cylinder device 114 is controlled to lift a blade 30. The blade 30 is pushed against the snow surface so as to obtain an optimum slip ratio. According to the constitution, unexpensive dectors can be used, as reliability and maintenance efficiency can be promoted.
