The specific embodiment
As shown in Figure 1; The described a kind of double dynamical coupling drive system of the utility model embodiment comprises main drive motor 1, auxilliary drive motor 2 and differential gear box 3, and said main drive motor 1 is connected with transmission gear 5 through output shaft 1; Driven wheel on transmission gear 5 and the differential gear box 3 is connected with a joggle; One side of differential gear box 3 is provided with free-wheel clutch 6, and the right half part of free-wheel clutch 6 is captiveed joint with differential gear box 3, and free-wheel clutch 6 is connected with auxilliary drive motor 2 through transmission shaft 7; The set inside of differential gear box 3 has planetary wheel 8; Planetary wheel 8 is connected with a joggle with left side axle side gear 9 and right axle gear 10 respectively, and left side axle side gear 9 is connected with free-wheel clutch 6 through described transmission shaft 7, and right axle gear 10 is connected with vehicle bridge through output shaft 2 11.
During concrete the use; Auxilliary drive motor 2 links to each other with left side axle side gear 9 with the left-half of free-wheel clutch 6 respectively through the spline on the semiaxis of left side; Free-wheel clutch 6 right half parts and differential gear box 3 are fixed together, thereby make free-wheel clutch 6 right half parts have identical rotating speed with differential gear box 4.
When main drive motor 1, auxilliary drive motor 2 rotating speeds opposite; The rotating speed of differential gear box 3 is identical with the rotary speed direction of auxilliary drive motor 2; Because being the rotating speed of power-transfer clutch left-half, the characteristic of free-wheel clutch 6 can not be higher than right half part; Therefore the rotating speed of auxilliary drive motor 2 can not be higher than the rotating speed of differential gear box 3, and two kinds of operating modes are arranged this moment, and promptly the rotating speed of the equal or auxilliary drive motor 2 of the rotating speed of the rotating speed of auxilliary drive motor 2 and differential gear box 3 is less than the rotating speed of differential gear box 3.
Operating mode one: auxilliary drive motor 2 is identical with differential gear box 3 rotating speeds
Wherein
,
,
are respectively the rotating speed of auxilliary drive motor 2, differential gear box 3 and output shaft 2 11, and
,
,
are respectively the torque of motor
, differential gear box 3 and output shaft 2 11.Rotating speed through changing main drive motor 1, auxilliary drive motor 2 changes the speed of a motor vehicle, because the torque of output is the stack of two drive motor, 1,2 torques, therefore can satisfy the requirement of heavy load power such as climbing.
The feedback braking of energy under this operating mode:
Mouth load meeting band 1,2 rotations of two drive motor during brake, thereby charges the battery energy recovery.The motor controller controls motor is in power generation mode during brake, the mouth load drive electric power generation and with electrical power storage in closed-center system (battery), braking energy feedback.
Operating mode two: auxilliary drive motor 2 is different with the rotating speed of differential gear box 3; Promptly auxilliary drive motor 2 rotating speeds are less than differential gear box 3, and this moment, diff began differential action, because auxilliary drive motor 2 rotating speeds are less than the rotating speed of differential gear box 3; So auxilliary drive motor 2 is in regenerating condition always; Promptly auxilliary drive motor 2 is charging the battery always, and the energy part of main drive motor 1 offers the mouth powered vehicle and goes, and a part is passed battery back through auxilliary drive motor 2 feedbacks.Relation by the diff rotating speed
The rotating speed that gets mouth 11 is:
Wherein
is respectively the rotating speed of auxilliary drive motor 2, differential gear box 3 and mouth 2 11; Along with the rotating speed of assisting drive motor 2 constantly descends; It is that the speed of a motor vehicle constantly raises that the rotating speed of mouth 2 11 constantly raises; But propulsive effort constantly reduces, and can be made by the transport characteristics of diff that propulsive effort is minimum to drop to
(the wherein torque of
differential gear box).To be 0 until auxilliary drive motor 2 rotating speeds, this moment, mouth 2 11 can reach maximum speed of revolution
.When this operating mode is applicable to high vehicle speeds, and stepless change.
Because auxilliary drive motor 2 is in regenerating condition under this operating mode, so this mechanism is equally applicable to hybrid power, can main drive motor 1 be changed to driving engine always, the engine operation motor is given batteries charging under this operating mode.
Vehicle all can have braking energy feedback with above-mentioned two kinds of operating modes are identical under this operating mode when drag; The utility model can be realized the reverse gear of vehicle equally, makes the counter-rotating of main drive motor 1 can realize reversing gear of car.In addition when auxilliary drive motor 2 broke down, vehicle also can cruising.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
