First vibration energy recovery device of the present invention is installed on vehicle, before installation, original vehicle damper need to be unloadedUnder, vibration energy recovery device being installed to the position of damper, vibration energy recovery device is by upper end and the car of mounting cylinder 1Body end is connected, is connected with vehicle nonspring carried mass by the two-sided rack 4, and between the two-sided rack 4 and vehicle nonspring carried massReload buffer spring, to play the effect of vehicle shock absorber.
When Vehicle Driving Cycle is when jolting road surface, the impact meeting that road surface produces wheel is transferred to buffer spring through nonspring carried mass, entersAnd pass to the two-sided rack 4, and now suspension is in compressed process, and the two-sided rack 4 moves upward, and then drives the first transmissionGear 2 rotates counterclockwise, and drives the second travelling gear 3 to clockwise rotate simultaneously;
When the first travelling gear 2 rotates counterclockwise, can drive the input of the first one-way clutch 5 to rotate counterclockwise,Now the first one-way clutch 5 is in engagement, and the output of the first one-way clutch 5 is for rotating counterclockwise, and then bandMoving the first row star-wheel 8 rotates counterclockwise;
When the second travelling gear 3 clockwise rotates, can drive the input of the second one-way clutch 6 to clockwise rotate,Now the second one-way clutch 6 is in released state, and the input of the second one-way clutch 6 is non-interference with respect to output;
When the first row star-wheel 8 rotates counterclockwise, by the transfer function of ring gear 7 and centre wheel 10, drive the second rowStar-wheel 9 and the third line star-wheel 11 rotate counterclockwise, because the second one-way clutch 6 is in released state, and the second planetary gear 9 meetingsDrive the output of the second one-way clutch 6 to rotate counterclockwise;
Under the first row star-wheel 8 rotates counterclockwise, centre wheel 10 clockwise rotates, through the speedup of gear speeder 12Effect, drives generator 13 to generate electricity, and has realized the charging of battery 14.
Otherwise when suspension is during in resilience state, suspension is in drawing process, the two-sided rack 4 moves downward, and then bandMoving the first travelling gear 2 clockwise rotates, and drives the second travelling gear 3 to rotate counterclockwise simultaneously;
When the first travelling gear 2 clockwise rotates, can drive the first one-way clutch 5 inputs to clockwise rotate, thisTime the first one-way clutch 5 in released state, the first one-way clutch 5 inputs are non-interference with respect to output;
When the second travelling gear 3 rotates counterclockwise, can drive the input of the second one-way clutch 6 to rotate counterclockwise,Now the second one-way clutch 6 is in engagement, and the output of the second one-way clutch 6 is for rotating counterclockwise, and then bandMoving the second planetary gear 9 rotates counterclockwise;
When the second planetary gear 9 rotates counterclockwise, by the transfer function of ring gear 7 and centre wheel 10, drive the first rowStar-wheel 8 and the third line star-wheel 11 rotate counterclockwise, because the first one-way clutch 5 is in released state, and 8 meetings of the first row star-wheelDrive the first one-way clutch 5 output rotate counterclockwise;
Under the second planetary gear 9 rotates counterclockwise, centre wheel 10 clockwise rotates, through the speedup of gear speeder 12Effect, drives generator 13 to generate electricity, and has realized the charging of battery 14.
So, no matter vehicle suspension is under which kind of state, can both realize the recovery of vibrational energy, by the buffering elastic installing additionalSpring, has ensured the comfortableness that car two is taken, and makes the present invention can replace existing vehicle shock absorber completely, and does not affect existing carStructure, kill two birds with one stone.
