Machine, system output is output shaft, and engine clutch makes engine output shaft be connected with corresponding power intake.
Specific torque relationship are as follows: Tout=TengK/ (1+k), wherein k is planet row gear ring radius and sun gear radius
Ratio, TengFor the torque of engine, ToutFor the output torque of output shaft.Middle friction tray is combined with left frictional disk, can will too
Sun wheel is locked, and the rotation of driven by engine planet carrier directly drives gear ring and rotated, and then by power by exporting in output shaft,
Realize engine direct drive.
4, Brake energy recovery mode
Under the mode, middle friction tray is in an intermediate position, is not combined with left frictional disk and right frictional disk, due to the second electricity
Machine is connected directly with gear ring, and braking energy relies primarily on the recycling of the second motor.Under Brake energy recovery mode, engine not work
Make, the second motor becomes generator, braking energy is converted to power storage in power battery.
When practice, since braking time is shorter, the time existing for Brake energy recovery mode is also shorter, if second
Clutch is also provided between motor and planet row, although the loss of energy can be reduced under engine direct drive mode, braking
It needs in a short period of time to close the clutch between the second motor and planet row under energy recuperation mode, it is virtually impossible to real
It is existing, therefore, in actual utilization, it is more harm than good that clutch is set between the second motor and planet row.Therefore, actual conditions
Under, the second motor is connected directly with planet row.
In the present invention, engine output shaft, first motor output shaft and the second motor output shaft are arranged side by side, and avoid same
Two motors must be made into the mode of hollow shaft and manufacture difficulty and manufacturing cost is caused to increase when axis is arranged.In the present embodiment,
The axis of three is parallel to each other, in other embodiments, at an angle can arrange between three.In the present embodiment, the
One motor is stand-by motor, and the second motor is driving motor.
In the present embodiment, middle friction tray is the second frictional disk, and left frictional disk is third frictional disk, and right frictional disk is
First frictional disk.When middle friction tray is in conjunction with right frictional disk, bidirectional clutch is in connection position, middle friction tray and left frictional disk knot
When conjunction, bidirectional clutch is in locked position, when middle friction tray is not combined with left frictional disk and right frictional disk, at bidirectional clutch
In disengaging position.In the present embodiment, third gear is sub-motor gear, and third gear shaft is sub-motor gear axis.
