Abstract
The utility model relates to an energy storage and transduction device of a pure electric vehicle, which is mainly characterized by comprising an inertial energy storage plate and a one-way overrun clutch, wherein the one-way overrun clutch can be fixedly arranged on a driving shaft, and the inertial energy storage plate is fixedly arranged on the outer periphery of the one-way overrun clutch. The energy storage and transduction device has the functions of storing energy and releasing kinetic energy, so that the electric vehicle can have small instantaneous peak value current when being started, namely the electric vehicle can be started under the conditions of low voltage and low current and have equal torque. The energy storage and transduction device of the pure electric vehicle is especially suitable for being configured on pure electric vehicles.
Description
Technical field
The utility model relates to engineering part, is a kind of energy storage transducing head of pure electric vehicle.
Background technology
In the prior art, the engine installation of automobile mainly is spark ignition engine and diesel engine.Along with people to the cry that reduces environmental pollution under the natural resources condition less and less such as more and more higher and oil, the actuating device such as pure electronic of hybrid power, battery+electrical motor is developed by leaps and bounds.At present, the pure electric automobile in research and development, electrical motor generally adopt permanent magnet direct current motor, and be battery-powered.Because being load zero stall when using on pure electric automobile, existing dc permanent magnet motor starts, its instantaneous peak current generally all will exceed several times even tens times of rated operational current, big instantaneous peak current like this, exceed battery allow to spark several times even tens times of electric current index, then accumulator electrode very easily damages under long-term electrical motor instantaneous current impacts, so what existing storage battery occurs recycles the life-span number of times less than 30%, a group storage battery of car load is recycled continuously travel total kilometrage less than service life of 30,000 kilometers.For a long time, people generally believe that motor technology reaches its maturity, but battery still has many deficiencies, as capacity, quality, charging times, charging rate or the like.The inventor recognizes through development research for many years, and the main bottleneck of pure electric automobile that designs battery+electrical motor at present is neither electrical motor, neither battery, but lack a kind of can store mechanical can the energy storage transducing head.
Summary of the invention
The purpose of this utility model provides a kind of energy storage transducing head of pure electric vehicle, make it can accumulation of energy energy storage when the electrical motor idling, and the energy storage transducer can discharge kinetic energy with idle work when the electrical motor stall, so just can overcome load zero stall effectively and start the too high and problem of infringement battery of instantaneous peak current, thereby improve the circulation repeated usage life-span of storage battery, and can effectively improve the driveability ability of pure electric automobile and the electric energy effective rate of utilization of accumulator capacity improves once electrically-charged continual mileage.
The technical solution of the utility model that realizes above-mentioned purpose is, is provided with a closed-center system at the mouth of axle drive shaft.Closed-center system in the utility model is a kind of inertia energy storage dish, simultaneously, also include one can with axle drive shaft ingear mono-directional overrun clutch; Said inertia energy storage dish is packed on the excircle of mono-directional overrun clutch.
As above said inertia energy storage dish can be that a kind of pull back spring by a disk body, polylith reducing slide block and respective numbers is formed in the utility model; Disk body evenly is separated into a plurality of radially cells, and each radially is provided with a reducing slide block in the cell, and the reducing slide block connects with a termination of pull back spring, and the other end of pull back spring connects firmly on the excircle of mono-directional overrun clutch.Said reducing slide block can include three, four, five, six ... nine.On this inertia energy storage dish, also be provided with an output shaft.
After the utility model is configured in battery-powered motor output end as mentioned above, can implement the segmentation of motor deceleration gap bridge, energy storage and reducing, idle.When turning on the power switch, can be powered by the program of setting by controller makes the inertia energy storage dish begin energy storage work to the idle task driven mono-directional overrun clutch of electrical motor, reducing slide block in the energy storage dish of this moment outwards slides it with the effect of the idle speed value of the increase of energy storage value and setting and enlarges span to desired location, when need not outside to use the propulsion source of power output shaft, when the energy storage dish has stored enough energy value again and has reached the idle speed value of setting, can stop idling energy storage work in the control motor, make energy storage dish under the energy that store foot begin conversion and idle work by separating the energy storage dish with mono-directional overrun clutch that motor shaft links this moment.When the energy storage dish when conversion does not also have extraneous required propulsion source in the idling work, by will be discharged into the limit to energy stored the time, may command follow procedure turn-on power is powered to electrical motor again, the idle at once work of electrical motor is also ordered about the energy storage dish by mono-directional overrun clutch and is proceeded energy storage, repeats automatic operation with this.
Structure as seen from the above mentioned, because pure electric vehicle disposes the utility model, then can the accumulation of energy energy storage during electrical motor idling, and can stop that the energy storage transducing head can discharge kinetic energy under the situation at electrical motor, idle work, so during the utility model work, the zero blocking-free start instantaneous peak current of electrical motor is little, its instantaneous peak current is in electrical motor allows the working current value scope of maximum power; Electrical motor just can start under the little current status of low voltage, and can have equal moment of torsion; Operating temperature of the present invention is low, and temperature rise is less than 100 ℃.
