Background technique

Vibration damper is the critical component of vehicle suspension system, main be damping with acting on, keep and provide vehicle riding comfort and stability.Vibration damper is hydra-shock absorber basically at present; Mainly be to move up and down through shock absorber piston; Make the oil of vibration damper get into another chamber through different Kong Congyi chambeies, the intermolecular interior friction of this moment hole wall and oil drag and fluid produces resistance to vibration, and making the Vehicular vibration Conversion of energy is fluid heat energy; Be dispersed in the environment by the vibration damper absorption, this part energy is not utilized again.

Summary of the invention

The utility model purpose has provided a kind of vehicle generating damping device, can not only make vehicle damping, and can utilize the energy of vibration damper to generate electricity.

To achieve these goals, the utility model adopts following technological scheme:

A kind of vehicle generating damping device, it comprises two cover vibration absorption unit, two sleeving valve roads and generator units, vibration absorption unit comprises oil hydraulic cylinder; The valve road comprises first one-way valve, second one-way valve, the 3rd one-way valve and the 4th one-way valve; Generator unit comprises variable displacement motor and generator; Oil hydraulic cylinder epicoele inlet connects fuel tank through first one-way valve, and the epicoele outlet is through second one-way valve link variable motor inlet; Oil hydraulic cylinder cavity of resorption inlet connects fuel tank through the 3rd one-way valve, and the cavity of resorption outlet is through the 4th one-way valve link variable motor inlet.

Further, variable displacement motor links to each other with the sensor of vehicle.

Further, it also comprises the additional fuel tank that is arranged on the variable displacement motor outlet port.

The beneficial effect of the utility model:

1, can not only make vehicle damping, and can utilize the vibration damper energy to generate electricity, can improve the stability of trailer reversing.

2, can utilize automobile sensor controlled variable motor displacement, realize ACTIVE CONTROL.At zig zag, when anxious acceleration and emergency braking, it is comparatively hard that passenger can be experienced suspension, and at cruising and soft.

3, when a cylinder pressure raises suddenly in this system, locking leads to the one-way valve of another oil hydraulic cylinder automatically, has realized single hydraulic cylinder self locking function, and the oil hydraulic cylinder of homonymy suspension does not produce mutual interference, does not need electronic control;

4, can utilize the sensor of vehicle self, not need extra setting.

5, the shared generator unit of single wheel is practiced thrift vehicle body space, has reduced cost.

Description of drawings

The selected embodiment's of Fig. 1 the utility model structural representation.

Fig. 2 is the utility model user mode schematic representation.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain, following explanation only is exemplary, does not limit the protection domain of the utility model.

With reference to accompanying drawing 1, a kind of vehicle generating damping device, it comprises two cover vibration absorption unit, two sleeving valve roads and generator units, vibration absorption unit comprises oil hydraulic cylinder 4; The valve road comprises first one-way valve 2, second one-way valve 5, the 3rd one-way valve 3 and the 4th one-way valve 6; Generator unit comprises variable displacement motor 8 and generator 9; Oil hydraulic cylinder 4 epicoeles inlet connects fuel tank 1 through first one-way valve 2, and the epicoele outlet is through second one-way valve, 5 link variable motors, 8 inlets; Oil hydraulic cylinder 4 cavity of resorptions inlet connects fuel tank 1 through the 3rd one-way valve 3, and the cavity of resorption outlet is through the 4th one-way valve 6 link variable motors 8 inlets.

Variable displacement motor 8 of the present invention links to each other with the sensor 7 of vehicle; Sensor 7 comprises the front of the car height sensor; Back height sensor, wheel steering and rotary angle transmitter, TPS and vehicle speed sensor; Can realize the adjusting of each suspension damping rigidity through the control motor displacement.

The present invention also comprises the additional fuel tank 10 that is arranged on variable displacement motor 8 outlet ports, is used for compensation and reclaims oil plant.

With reference to accompanying drawing 2, use two vehicle generating damping devices on a kind of automobile, when the automobile urgent brake car; It is very big to detect vehicle deceleration by vehicle speed sensor, is judged to be emergency braking, reduces the discharge capacity of the variable displacement motor 8 of the left and right sides simultaneously; This moment, automobile had the braking nose dive phenomenon, and oil hydraulic cylinder oil pressure promptly left front and right front suspension increases suddenly, and the one-way valve that pins left back and right back oil hydraulic cylinder respectively prevents that fluid from recharging; Flow back to oil sump tank through variable displacement motor 8 then; But because this moment, the variable displacement motor discharge capacity reduced, it is slower that fluid is got into the speed of oil sump tank, so this moment, left front suspension damping rigidity with forward right side increased; Effectively prevent braking nose dive, improved the travelling comfort of vehicle.

When automobile quickened suddenly, it was very big to detect vehicle acceleration by vehicle speed sensor, and TPS detects aperture change suddenly greatly; Be judged to be anxious acceleration, reduce the discharge capacity of the variable displacement motor of the left and right sides simultaneously, this moment, automobile had the recoil phenomenon; Be that left back and oil hydraulic cylinder oil pressure right rear suspension increase suddenly; The one-way valve that pins left front and right front oil hydraulic cylinder respectively prevents that fluid from recharging, and flows back to oil sump tank through variable displacement motor then, but because the variable displacement motor discharge capacity reduces at this moment; It is slower that fluid is got into the speed of oil sump tank; So this moment, the suspension damping rigidity of left back and right lateral side increased, recoil phenomenon when effectively having prevented acceleration has improved the travelling comfort of vehicle.

When vehicle takes a sudden turn; There are wheel steering and rotary angle transmitter to judge turn direction and size, reduce the discharge capacity of outside variable displacement motor, increase the discharge capacity of inboard variable displacement motor; Realize that outside suspension damping rigidity increases; Inboard suspension damping rigidity reduces, and improves automobile ride, effectively prevents rollover.

The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any type of restriction,, can not be used to limit the utility model though the utility model has disclosed through the foregoing description; The technology contents of those skilled in the art's above-mentioned announcement capable of using is made many variations or improved equivalent embodiment, and these equivalent embodiments should belong to the scope of the technological scheme of the utility model.
