Abstract
Fluid pressure type vehicle kinetic energy recovery system, the brake kinetic energy that can be used to various vehicles such as automobile, motorcycle, electric motor car, bicycle is retrieved and is recycled, can reduce the vehicle and be expert at and sail the in -process because energy loss that frequent brake led to the fact, improving energy efficiency. Fluid pressure type vehicle disc brake kinetic energy recovery system is become with the switching -over valves by brake coupling, hydraulic pump, pneumatic cylinder, hydraulic motor, drive clutch and supporting check valve, overflow valve, choke valve. Its know -why is: when the car brakeing, the vehicle shaft passes through the brake coupling and drives the hydraulic pump to the pneumatic cylinder oil transportation, and with the automobile body jack -up that makes progress, kinetic energy turns into gravitional force after the pneumatic cylinder extension, when the braking finished the vehicle and starts to walk again, automobile body dead weight compression pneumatic cylinder arranged oil to hydraulic motor, and hydraulic motor drives the drive clutch and acts on the vehicle shaft, and the drive vehicle moves ahead, and gravitional force turns into kinetic energy again.
Description
Technical field
The present invention relates to a kind of novel hydraulic vehicle kinetic energy recovery system, can be used for brake recover kinetic energy and the recycling of the various vehicles such as automobile, motor bike, battery-driven car, bicycle, vehicle can be reduced in the process of moving due to the waste of power that frequently braking causes, improve energy utilization rate.
Background technology
Along with science and technology constantly progress, Living consumption improves constantly, and automobile has become the trip instrument of daily life indispensability.By the end of 2014, world car recoverable amount reached 8.5 hundred million, and wherein China's automobile guarantee-quantity reaches 2.6 hundred million, and in continuous rising tendency.What day by day highlight along with huge total vehicle is more serious environmental pollution and energy shortage problem, how to reduce fuel oil consumption and the pollutant discharge amount of automobile, realizing low-carbon environment-friendly trip, is the urgent and severe problem of in face of us one of pendulum.
Vehicle waste of power in the process of moving, the overwhelming majority occurs in the brake process of vehicle, particularly on the urban highway day by day blocked up, along with braking continually, the kinetic energy of automobile is converted into heat energy by the friction of brake facing, is a kind of energy dissipation greatly, also therefore, with recover kinetic energy of braking for problem, various countries expand to be studied widely, and current research direction mainly contains mechanical type brake recover kinetic energy and electromagnetic brake recover kinetic energy Liang Ge branch.
Comparatively famous in mechanical type brake kinetic energy recovery system is the flywheel-type braking kinetic energy recovery device be applied in F1 racing car, its know-why passes through gear transmission, be the rotation potential energy of flywheel by kinetic transformation, when vehicle is started to walk again, energy back drives automobile to advance in transmission shaft by gear by flywheel again.The shortcoming of technique is when depressing braking time and being long, flywheel dally for a long time and with air and bearing friction, degradation of energy is comparatively large, is applicable to the brake in short-term when crossing curved during racing track travels and accelerates, being not suitable for travel conditions modern urban road having longer parking period; In addition, the size of flywheel stored energy depends on rotating speed and the deadweight of flywheel, when Speed of Reaction Wheels is too high, the degradation of energy caused with air or bearing friction obviously increases, and when flywheel deadweight increases, complete vehicle weight can be increased again simultaneously, reduce fuel economy on the contrary.Due to the shortcomings of technique, make it and fail to be applied widely.
The principle of electromagnetic brake kinetic energy recovery system passes through generator set, be that electric energy carries out storing and recycling by kinetic transformation, the shortcoming of technique is that electric energy generated depends on magnetic field power and coil winding number, the operation of other electronic components in car and the personnel health that rides can be affected during high intensity magnetic field, increase coil winding number and can increase complete vehicle weight again, therefore be only applied in minority family expenses vehicle at present, electric energy generated is also less, only can as the auxiliary power supply of electrical equipment in car.
Under this technical background, develop fluid pressure type brake kinetic energy recovery system, this system is compared to mechanical type and electromagnetic brake kinetic energy recovery system, there is structure simple, energy transformation ratio is high, and the storage time is long, drives the advantages such as steady, can be applied in any type of vehicle, there is promotion prospect comparatively widely.
Summary of the invention
In order to be for recycling and reuse by the kinetic energy of loss during braking automobile, reduce energy dissipation, reduce fuel oil consumption, invented hydraulic vehicle brake kinetic energy recovery system.It is characterized in that: hydraulic vehicle brake kinetic energy recovery system is made up of brake coupling, Hydraulic Pump, hydraulic actuating cylinder, HM Hydraulic Motor, driving clutch and supporting check valve, by pass valve, flow regulating valve and change-over valve, wherein brake coupling and driving clutch and vehicle wheel shaft are connected, it is the input and output port of energy, hydraulic actuating cylinder is installed between vehicle hanging and vehicle body, can by vehicle body upwards jack-up.Its know-why is: when car brakeing, and vehicle axles drives Hydraulic Pump to hydraulic actuating cylinder oil transportation by brake coupling, and by vehicle body upwards jack-up after hydraulic actuating cylinder extends, kinetic transformation is gravitional force; When end of braking vehicle is started to walk again, vehicle body deadweight compression hydraulic cylinder is by oil discharged to HM Hydraulic Motor, and HM Hydraulic Motor drives driving clutch to act on vehicle axles, and drive vehicle forward, gravitional force is converted into kinetic energy again.

Detailed description of the invention
When normal vehicle operation, brake coupling 03 and driving clutch 13 are all in released state, and fluid pressure type brake kinetic energy recovery system is in off position, as shown in Figure 2.
When driver steps on brake pedal, braking procedure starts, brake coupling 03 combines, driving clutch 13 is separated, and change-over valve 11 is switched to closed condition, and the transmission gear 02 that rotates through of wheel passes to brake coupling, and drive Hydraulic Pump 05 to rotate beginning to hydraulic actuating cylinder 09 oil transportation, by vehicle body 10 upwards jack-up after hydraulic actuating cylinder 09 extends, brake kinetic energy is converted and saves as the gravitional force of vehicle body, thus achieves the removal process of energy.In the process, filter 04 serves the effect of clean oil circuit, and overflow 08 serves the effect of pressure protect, and adjust flux is responsible for by flow regulating valve 07, ensures the steady lifting of hydraulic actuating cylinder 09, and check valve is responsible for blocking backflow, keeps the lifting state of hydraulic actuating cylinder.Energy recovery process during car brakeing as shown in Figure 3.
When vehicle is started to walk again, brake coupling 03 is separated, driving clutch 13 combines, change-over valve 11 is switched to open mode, and vehicle body 10 starts to decline under self gravitation impact, and oil is discharged by compression hydraulic cylinder 09 simultaneously, HM Hydraulic Motor 12 is driven to rotate, pass to gear cluster 02 by driving clutch 13, drive vehicle wheel rotation, thus achieve the recycling process of energy.In the process, flow regulating valve serves adjust flux, ensures the function that power steadily exports.Energy recycling process during vehicle recurrence step as shown in Figure 4.
