Description
Technical field
The present invention relates to a kind of actuating device, be specifically related to a kind of energy-saving driving device of new-energy automobile.
Background technology
Facing mankind fossil energy and is petered out; and depend on the ecological deterioration two that fossil energy causes unduly and challenge greatly; take petroleum-based energy as the fast development of the orthodox car of power; the mankind are made to be absorbed in the Double jeopardy of scarcity of resources and ecological deterioration; therefore, the new-energy automobile developing energy-conserving and environment-protective becomes the development tendency of industry gradually.Described new-energy automobile refers to that propulsion source has except driving engine, also includes the automobile of other propulsion source.
The braking of automobile is realized by brake disc and brake clamp or the friction between brake wheel and brake shoe brake cheek.In the process, car load kinetic energy is dissipated with the form of heat by friction, causes the waste of energy.Particularly in the operating mode of city, because traffic congestion and transport administration need, vehicle needs to accelerate repeatedly, slow down, and the energy that braking consumes consumes in gross energy at vehicle and occupies sizable ratio.
Braking energy feedback is the very important means improving automobile energy efficiency, it typically refers to electronlmobil (such as pure electric automobile and hybrid vehicle) in deceleration or descending process, under the prerequisite ensureing deceleration and stopping performance, the inertia energy of running car is passed to motor by driving system, motor works in either a generation, for closed-center system charging, thus the feedback realizing braking energy utilizes.Braking energy feedback can promote the continual mileage of electronlmobil, reduces the weight of on-vehicle battery.In addition, the wearing and tearing of brake bush can also be reduced.

The concise and to the point description of specific works process of the present invention is: when vehicle first time starts to walk, flywheel 4 rotating speed is zero, and not store mechanical energy in flywheel 4, at this moment, electric controller DK passes through fly wheel brake 5 by flywheel 4 locking, if electric controller DK drives the first motor/generator 1 and the second motor/generator 7-5 to work simultaneously, now, gear ring 7-1 and sun wheel 7-4 rotates, and pinion carrier 7-3 does not rotate, and the torque T of the second motor/generator 7-5
cmbe added on clutch end after power coupling transmission component 7 amplifies k times, then add the breakaway torque of car load, reduce pick-up time, during starting, the torque of wheel is
Along with the increase of the speed of a motor vehicle, namely drive the rotating speed n of wheel
wincrease, the rotating speed n of the second motor/generator 7-5
cmproportional increase simultaneously.Namely
When vehicle needs to slow down, fly wheel brake 5 is released by electric controller DK, applies a negative torque T to the second motor/generator 7-5 simultaneously
cm, namely enter generating state, the second motor/generator 7-5 reduces speed now, and now, pinion carrier 7-3 rotates, and flywheel driven 4 also rotates.Like this, be applied on clutch end after the negative torque of the second motor/generator 7-5 amplification by power coupling transmission component 7, car brakeing feedback torque T can be presented as
br, make car retardation.Namely
This torque is simultaneously applied on flywheel 4 by planetary wheel 7-2, pinion carrier 7-3 and the second motor/generator 7-5, makes flywheel 4 enter acceleration mode, and namely flywheel 4 torque is
Now flywheel 4 accelerates, and the second motor/generator 7-5 and car retardation, namely the kinetic energy part before car brakeing is generated electricity by the second motor/generator 7-5 and is entered storage battery, and a part is converted into the mechanical energy of flywheel 4 in addition, is stored in flywheel 4.Flywheel 4, second motor/generator 7-5 and vehicle wheel rotational speed meet simultaneously
Because the inertia of vehicle is comparatively large, and the rotor inertia of flywheel 4 and the second motor/generator 7-5 is less, makes the deceleration of the second motor/generator 7-5 faster than the deceleration of entire vehicle, therefore, when the rotating speed of the second motor/generator 7-5 is reduced to zero, at this moment, the speed of a motor vehicle is still higher.If also need car retardation, at this moment still apply negative torque to the second motor/generator 7-5, the second motor/generator 7-5 enters as reciprocal acceleration mode, namely enters motoring condition.At this moment the kinetic energy of vehicle is all converted into the kinetic energy of flywheel 4, a part of electric energy conversion is also the kinetic energy of flywheel 4 by the second motor/generator 7-5 simultaneously, flywheel 4 continues to accelerate, until car retardation stops, now flywheel 4 still keeps high rotating speed, second motor/generator 7-5 keeps negative rotating speed, namely
Now, if vehicle needs to accelerate, then positive torque is applied to the second motor/generator 7-5, enter generating state, second motor/generator 7-5 starts reverse deceleration, and this positive torque is simultaneously applied to clutch end after being amplified by power coupling transmission component 7, for wheel accelerates to provide power; This torque simultaneously is also applied on high speed flywheel 4 by power coupling transmission component 7, makes flywheel 4 slow down (torque relation is with above-mentioned moderating process).Namely a kinetic energy part for flywheel 4 is converted into electric energy by the second motor/generator 7-5, and a part is converted into the kinetic energy of vehicle in addition.
Along with the continuation of vehicle acceleration state, after the second motor/generator 7-5 is oppositely decelerated to zero rotating speed, then continue to apply forward torque to the second motor/generator 7-5, second motor/generator 7-5 starts forward to accelerate, enter motoring condition, until vehicle acceleration terminates (rotation speed relation is contrary with above-mentioned moderating process).
Be more than one complete from the description decelerating to accelerator.
If when the mechanical energy that flywheel 4 stores is zero, electric controller DK again by flywheel 4 locking by fly wheel brake 5, when slowing down to vehicle, again can be discharged flywheel 4, making flywheel 4 store mechanical energy.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
