Abstract:
1. A hybrid power drive system, comprising: an engine; a first motor; a first clutch operatively coupled between the engine and the first motor; a first decelerating mechanism having an input portion and an output portion, the input portion operatively coupled between the first clutch and the first motor, the input portion configured to receive rotational power from at least one of the first motor and the engine; the first decelerating mechanism having an output portion operative to drive at least one wheel of a first wheel set; a second decelerating mechanism having an input portion and an output portion; a second motor operatively coupled to at least one wheel of a second wheel set through the second decelerating mechanism; an energy storage device coupled separately to the first motor and to the second motor; and wherein, the engine, the first clutch and the first motor are connected in sequence, and the second decelerating mechanism and the at least one second wheel are connected in sequence; and wherein the first and second decelerating mechanisms are configured to decelerate a rotational speed of the corresponding output portion relative to the corresponding input portion, wherein a rotation speed of the corresponding input portion is substantially greater than the rotational speed of the corresponding output portion.
