DRIVING FORCE DISTRIBUTING DEVICE

摘要

A driving force distributing device includes a single pump for supplying control hydraulic pressure to each of first and second hydraulic clutches, an electric motor for driving the pump, a flow rate variable mechanism for changing a ratio of flow rate of hydraulic fluid supplied to each of the first and second hydraulic clutches and a controlling means for controlling the electric motor and the flow rate variable mechanism. The driving force distributing device can variably control a flow rate of hydraulic fluid supplied to first and second hydraulic clutches based on changing a ratio of flow rate of hydraulic fluid supplied to the first and second hydraulic clutches in the flow rate variable mechanism and a control of changing rotational speed of the pump using the motor.

1. A driving force distributing device comprising a first hydraulic clutch and a second hydraulic clutch for distributing driving force from a driving source to each of a pair of driving wheels,
the driving force distributing device for distributing driving force to each of the pair of driving wheels by variably controlling engaging force of each of the first and second hydraulic clutches according to running conditions of a vehicle, the driving force distributing device comprising: a single pump for supplying control hydraulic pressure to each of the first and second hydraulic clutches; an electric motor for driving the pump; a flow rate variable mechanism for changing a ratio of flow rate of hydraulic fluid supplied from the pump to each of the first and second hydraulic clutches; and a control means for controlling the electric motor and the flow rate variable mechanism, wherein the driving force distributing device controls driving force distributed each of the pair of driving wheels by variably controlling a flow rate of hydraulic fluid supplied to the first hydraulic clutch from the pump and a flow rate of hydraulic fluid supplied to the second hydraulic clutch from the pump separately on the basis of a control of changing a ratio of the flow rate of hydraulic fluid supplied to each of the first and second hydraulic clutches from the pump in the flow rate variable mechanism and a control of a rotational speed of the pump using the electric motor.
