Description
Technical field
The utility model relates to road roller, especially a kind of hybrid power road roller.
Background technology
Road roller belongs to the category of road furniture in engineering machinery, the embankment compacting operation that is widely used in the Larger Engineering Projects such as high-grade highway, railway, airfield runway, dam, stadium, can roll sand, half viscosity and clayed soil, subgrade stability soil and asphalt concrete pavement layer.The inertia force that vibratory roller utilizes the interior device of road roller cylinder rotating eccentricity wheel to produce makes road roller produce shock, compacting road surface.Vibration force than road roller from great several times.During operation, road roller is answered after head start could starting of oscillation, and internal combustion engine should be first as for middling speed, and then is adjusted at a high speed.Vibratory roller surge when starting of oscillation is higher, and power demand is larger; And when steady operation, operating pressure is lower, power demand is less.In order to meet starting of oscillation power requirement, need the motor that mesh power is larger, cause performance waste and cost to increase, efficiency is lower, poor work stability.
Summary of the invention
The purpose of this utility model is to provide a kind of hybrid power road roller, and solution single-power motor need to be equipped with the technical problem of relatively high power motor.
The purpose of this utility model realizes as follows: this hybrid power road roller design motivation components of system as directed, dynamical system comprises motor, transfer case, hydraulic pump, banked direction control valves, hydraulic motor, vibrating device, controller, electric generator/electric motor, electric storage device, engine output power connects transfer case, transfer case is connecting fluid press pump and electric generator/electric motor respectively, electric generator/electric motor is electrically connected with electric storage device, the hydraulic power of hydraulic pump is through banked direction control valves connecting fluid pressure motor, and hydraulic motor outputting power connects vibrating device; Controller is electrically connected with banked direction control valves, electric generator/electric motor, transfer case respectively.The power of this system engine is slightly larger than the required power of the normal steady operation of road roller.Like this, when the normal steady operation of road roller, engine power is divided into two-way by transfer case, one road drives hydraulic pump to produce pressure oil and drives hydraulic motor to drive vibrating device work, another road drives electric generator/electric motor as generator, generate electricity and store energy in electric storage device, and system is in energy storage state.During starting of oscillation, power demand is larger, and electric generator/electric motor is that system is supplemented the under-supply energy of motor as motor, and motor and motor are simultaneously for hydraulic pump provides energy, and system can state in releasing.Controller, according to the state of operating conditions system charging and discharging, meets the normal steady operation power demand different with starting of oscillation, guarantees that again motor operates in optimum Working all the time simultaneously.The utility model adopts hybrid power, braking and energy during failure of oscillation can also be reclaimed to storage.
Electric storage device is battery, super capacitor or ultracapacitor.
Super capacitor belongs to double layer capacitor, it is the one that has dropped in the world capacity maximum in the double layer capacitor of volume production, the double layer capacitor of its basic principle and other kind is the same, is all to utilize the double electrical layers of active carbon porous electrode and electrolyte ingredient to obtain the capacity of super large.
Ultracapacitor is a kind of novel energy storage device growing up the 1970s and 1980s in last century.It is a kind of between traditional capacitor and battery, there is the power supply of property, mainly rely on electric double layer and redox pseudocapacity charge storage electric energy, thereby be different from traditional electrochmical power source.The outstanding advantages of ultracapacitor is that power density is high, the time that discharges and recharges is short, have extended cycle life, operating temperature range is wide.
As similar designs of the present utility model, the mode that also can adopt hydraulic accumulator to carry out energy storage, saves transfer case of the present utility model, electric generator/electric motor, electric storage device, and after hydraulic pump and connect hydraulic energy storage device.Hydraulic accumulator is a kind of energy savings device in hydraulic system, it is in due course and changes the energy in system into compression energy or potential energy stores, when system needs, again compression energy or potential energy are changed into hydraulic energy and discharge, again mend feed system.When system instantaneous pressure increases, it can absorb this part energy, guarantees that whole system pressure is normal.
The utility model is considered respectively normal steady operation and two kinds of operating modes of starting of oscillation, and system is in the situation that having met main operating mode, and larger power demand while adopting auxiliary power reply starting of oscillation, can be used the motor of smaller power, and cost is lower; During normal work, power loss is little, and the power of motor is fully used, and has reduced energy consumption and discharge, better working stability.
