Description
Technical field
The present invention relates to a kind of parallel hydraulic battery-driven car regenerative braking energy reclaiming system.
Background technology
At present, carried out appreciiable research to the Regenerative Braking Technology of battery-driven car abroad, achieved obvious progress, many products can be applied on real vehicle.Oil-electric vehicle regeneration brake system, the external storage battery that adopts reclaims braking energy more.China's development battery-driven car, regenerative braking system of electric vehicle, proposes the regeneration brake systems such as storage battery, super capacitor, flywheel, hydraulic accumulator.Due to domestic on existing battery technology, very difficult storage battery or super capacitor do storage unit and reclaim braking energy.Series-connected regenerative brake system CPS (Constant Pressure Source), adopts level pressure source hydraulic-driven, and fly wheel system structure is simple, and fuel-saving efficiency is high, and shortcoming is that cost is high, is difficult to adapt to battery-driven car.
Summary of the invention
The present invention is directed to current fly wheel system cost high, be difficult to adapt to the narrow problem of battery-driven car, applicable area, propose a kind of applied widely, parallel hydraulic battery-driven car regenerative braking energy reclaiming system that cost is low.
A kind of parallel hydraulic battery-driven car regenerative braking energy reclaiming system 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 connects with described mechanical drive input shaft, and the output shaft of described mechanical drive is connected with wheel by drive axle; The power taking axle of described mechanical drive is connected with the input end of described retarder, and described retarder is connected with controllable capacity pump, and the pipeline of described controllable capacity pump is connected with fuel tank, and described flywheel is engaged 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 described energy storage is with described three-position four-way valve, be all connected by conduit under fluid pressure between described controllable capacity pump and described three-position four-way valve.
Described controllable capacity pump is arranged on described fuel tank by conduit under fluid pressure.
Described energy storage configures by pass valve, and described by pass valve is connected with described energy storage, described three-position four-way valve respectively by conduit under fluid pressure.
When battery-driven car first time starts, user carries out start-up operation, and storage battery discharges, starter motor, and the mechanical drive be now connected with motor transmits drive axle propulsive effort thus passes to wheel, thus starts automobile; When brake of electric vehicle, vehicle wheel rotation makes drive axle that moment of torsion has been passed to mechanical drive, and the deceleration through retarder has passed to controllable capacity pump moment of torsion, and power-transfer clutch engages, and makes flywheel turns, recuperated energy; When flywheel reaches critical speed soon, disengaging of clutch, the fluid in fuel tank flows into energy storage from fuel tank through three-position four-way valve and carries out energy storage, and unnecessary fluid flows into fuel tank through by pass valve; When also having unnecessary hydraulic energy, three-position four-way valve commutates, and hydraulic energy can be allowed to be stored in energy storage; When battery-driven car again starts or accelerates, motor starts transferring energy to drive battery-driven car, jointly automobile is driven with the energy that flywheel discharges, 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 battery-driven car, fluid through controllable capacity pump flows into fuel tank, will make battery-driven car than acceleration capacity grow when not having flywheel gear like this.
The invention has the beneficial effects as follows: applied widely, structure is ripe, cost is low, be convenient to repacking, achieve energy regenerating recycling.
