Background technology
At present, the Regenerative Braking Technology of electronlmobil carried out appreciiable research abroad, obtained obvious progress, many products can be applied at real vehicle.The oil-electric vehicle regeneration brake system, the external storage batterys that adopt reclaim braking energy more.China's Development of EV, the electronlmobil regeneration brake system has proposed the regeneration brake systems such as storage battery, super capacitor, flywheel, hydraulic accumulator.Since domestic on existing battery technology, be difficult to do storage unit with storage battery or super capacitor and reclaim braking energy.Series connection regeneration brake system CPS (Constant Pressure Source) adopts level pressure source hydraulic-driven, and fly wheel system is simple in structure, and fuel-saving efficiency is high, and shortcoming is that cost is high, is difficult to adapt to electronlmobil.
Summary of the invention
The present invention is directed to present fly wheel system cost high, be difficult to adapt to electronlmobil, the narrow problem of applicable area, a kind of applied widely, hydraulic electric automobile regenerative braking energy reclaiming system in parallel that cost is low has been proposed.
A kind of hydraulic electric automobile regenerative braking energy reclaiming system in parallel of the present invention, it is characterized in that: comprise storage battery, motor, mechanical drive, retarder, fuel tank, drive axle, flywheel and energy storage, described storage battery is electrically connected with described motor; The output shaft of described motor, described drive axle all join with described mechanical drive; The output shaft of described mechanical drive is connected with the wheel of automobile and the input end of described retarder respectively, and described retarder links to each other with fuel tank with controllable capacity pump, and described flywheel engages with described controllable capacity pump by power-transfer clutch; Described energy storage is connected with described controllable capacity pump by three position four-way directional control valve, and all links to each other by conduit under fluid pressure between described energy storage and described three-position four-way valve, described controllable capacity pump and the described three-position four-way valve.
Described controllable capacity pump is installed on the described fuel tank by conduit under fluid pressure.
Dispose by pass valve on the described energy storage, and described by pass valve links to each other with described energy storage, described three-position four-way valve respectively by conduit under fluid pressure.
When electronlmobil started for the first time, the user carried out start-up operation, and storage battery discharges, starter motor, and the mechanical drive that be connected with motor this moment passes to wheel to propulsive effort, thereby starts automobile; When automobile brake, vehicle wheel rotation makes drive axle pass to mechanical drive to moment of torsion, through the deceleration of retarder moment of torsion has been passed to controllable capacity pump, and power-transfer clutch engages, and makes flywheel rotate the recovery ability; When flywheel reached critical speed soon, disengaging of clutch, the fluid in the fuel tank flowed into energy storage from fuel tank through three-position four-way valve and carry out energy storage, and unnecessary fluid flows into fuel tank through by pass valve; When also having unnecessary hydraulic energy, the three-position four-way valve commutation can allow hydraulic energy be stored in the energy storage; When automobile started again, flywheel just can discharge the energy of storage, drove automobile and advanced; When automobile needs quick start, motor starts transferring energy, the energy that discharges with flywheel drives automobile jointly, the fluid of energy storage flows into controllable capacity pump through three-position four-way valve, drive controllable capacity pump and then provide moment of torsion to automobile, flow into fuel tank through the fluid of controllable capacity pump, the acceleration capacity grow that will make automobile like this when not having flywheel gear.
The invention has the beneficial effects as follows: applied widely, structure is ripe, cost is low, be convenient to the repacking, realized the energy recycling.
