PURPOSE:To make it possible to suitably distribute drive power in accordance with the running condition of a vehicle, by delivering a drive control signal for making a drive power distribution approach a four wheel drive condition, to a valve solenoid in response to increasing of a computed rotational speed difference between left and right wheels. CONSTITUTION:A drive power distributing device 10 comprises a drive power input shaft 11, a transmission unit 12, an input shaft 13, a rear wheel side drive shaft 14, multi-disc friction clutch 15, an oil pump 16, a hydraulic oil discharge pipe 17, an oil suction pipe 18, a reserve tank 19, a gear train 20 and a front wheel side drive shaft 21. Further, a drive power distribution control device 40 comprises a front and rear side rotational speed sensors 41, 42, a proportional constant setting means 44, a control unit 45, a valve solenoid 46, an electromagnetic proportional relief valve 47 and a branch drain pipe 48. The control unit 45 computes the rotational difference between the drive shafts 21, 14, and delivers, to the solenoid 46, a signal for making the distribution of drive power approach a four wheel drive condition in response to increasing of the rotational speed difference between the drive shafts 21, 14. |
