Description
Technical field
The present invention relates to a kind of energy-recuperation system, especially relate to a kind of energy-recuperation system of automotive engine.
Background technology
In the vehicle traveling process, when chaufeur unclamps Das Gaspedal, driving engine is in idle state, the power of driving engine output this moment is except offering electrical generator, air-conditioning compressor, power assistance pump for steering, water pump, some power is wasted, and this part energy that is lost is the energy more than needed of driving engine.In today of resource growing tension, how can energy-saving and emission-reduction, become the problem that car production producer more and more payes attention to.
Summary of the invention
The present invention be to provide a kind of can be in vehicle traveling process with the energy recovery more than needed of driving engine, and in needs, discharge, auxiliary engine drives running car, and supplies with the hydraulic power-assisted steering system of automobile at any time, this kind system architecture is simple in structure, and is easy to use, reliable.
Technical scheme of the present invention is: a kind of automotive engine energy-recuperation system, comprise with automobile gearbox countershaft-gear gears in mesh axle (1) and be installed in magnetic clutch (2) on the gear wheel shaft (1), it is characterized in that: described energy-recuperation system also includes fuel tank (7), pump-motor (3) and energy storage (5), described magnetic clutch (2) is positioned between described gear wheel shaft (1) and the described pump-motor (3), and hydraulic oil enters into described energy storage (5) after described pump-motor (3) pressurization.
Technical scheme of the present invention also has: between described pump-motor (3) and the described energy storage (5) hydraulic control one-way valve (4) is installed, solenoid directional control valve (6) is used to control described hydraulic control one-way valve (4).
Technical scheme of the present invention also has: described energy storage (5) connects the motor turning force aid system through check valve (8).
Native system with the energy recovery more than needed of driving engine, and discharges in needs in vehicle traveling process.In the removal process of energy more than needed, native system can not increase any added burden to automotive engine.During car acceleration, native system quits work automatically, does not influence the normal outputting power of driving engine, has therefore played the effect of good energy-saving and emission-reduction.
Description of drawings
Accompanying drawing 1 is the composition scheme drawing of this automotive engine energy-recuperation system, wherein, and 1 expression gear wheel shaft, 2 expression magnetic clutchs, 3 expression pump-motors, 4 expression hydraulic control one-way valves, 5 expression energy storages, 6 expression solenoid directional control valves, 7 expression fuel tanks, 8 expression check valves.
The specific embodiment
The native system major part comprises: gear wheel shaft 1, magnetic clutch 2, pump--motor 3, energy storage 5, fuel tank 7 and corresponding solenoid valve.When the auto idle speed running needs recovery to have more than needed energy, magnetic clutch 2 combinations, pump--motor 3 is worked in the mode of pump, the hydraulic oil in the fuel tank 7 is pressed in the energy storage 5 store; When the energy demand of being reclaimed discharges, magnetic clutch 2 combination once more, and this moment pump--motor 3 is with motor mode work, high pressure oil driving pump-motor 3 high speed revolutions in the energy storage 5, thereby auxiliary engine work is car acceleration; In vehicle traveling process, the regenerated energy in the energy storage 5 can be supplied with the motor turning force aid system at any time at running car or engine off state simultaneously, and like this, automotive engine does not just need to drive the boost pump acting.In the removal process of energy more than needed, native system can not increase any added burden to automotive engine.During car acceleration, native system quits work automatically, does not influence the normal outputting power of driving engine.
Gear wheel shaft 1 meshes with the countershaft-gear of Automotive transmission, and A face shown in the long and two-short dash line connects with automobile gearbox in the accompanying drawing 1.Connected by magnetic clutch 2 between pump--motor 3 and the gear wheel shaft 1, combination during magnetic clutch 2 energisings separates during outage.
Pump--motor 3 is axial plunger type variable capacity pumps--motor, energy storage 5 is a high pressure accumulator.Reclaim in the process of energy more than needed, pump-motor 3 is worked in the mode of pump, hydraulic oil is pressed into the energy storage 5 from fuel tank 7 store; The high pressure oil that stores reaches certain limit and need discharge when utilizing again, and pump--motor 3 rotates under the effect of high pressure oil with motor mode work, 1 rotation of driven gear axle, thus auxiliary engine work is car acceleration, hydraulic oil flow is got back to fuel tank 7 simultaneously.
For energy storage 5 is set recovery upper limit force value respectively, discharges upper limit force value, is discharged the threshold pression value, when the pressure of energy storage 5 reaches the recovery higher limit, energy recovery process end more than needed; When the pressure of energy storage 5 reached the release higher limit, auxiliary engine work began to release energy; When the pressure of energy storage 5 reaches the release lower limit, finish to release energy.Therefore, in vehicle traveling process, energy storage 5 can keep being not less than the pressure that discharges lower limit always, and such pressure is enough to provide constant voltage oil stream to the steering boost system of automobile.
Concrete working mechanism is as follows:
1, reclaims energy more than needed: begin recuperated energy when driving engine is in idling.Magnetic clutch 2 energising combinations in the removal process, pump--motor 3 is worked in the mode of pump, and hydraulic oil flows to energy storage 5 from fuel tank 7 through hydraulic control one-way valve 4.
2, recuperated energy finishes: the pressure that driving engine finishes idling or energy storage 5 reaches when reclaiming higher limit, and magnetic clutch 2 outages separate, and pump--motor 3 quits work.
3, discharge the energy that is reclaimed: in the process of car acceleration, the pressure of energy storage 5 reaches when discharging higher limit, magnetic clutch 2 energising combinations, solenoid directional control valve 6 energisings are opened, thereby make hydraulic control one-way valve 4 reversing sense conductings, and pump--motor 3 is with motor mode work, by magnetic clutch 2 driven gear axles 1, and then the rotation of driving automobile countershaft-gear, auxiliary engine work is car acceleration.
4, the end that releases energy: automobile finishes to quicken or energy storage 5 pressure reach when discharging lower limit, and magnetic clutch 2 outages separate, and solenoid directional control valve 6 outages are closed, thereby make hydraulic control one-way valve 4 close pump--and motor 3 quits work.
5, supply with boosting pump for car steering: in the vehicle traveling process, the pressure of energy storage 5 can remain on the state that discharges lower limit that is not less than always, thereby provides the pressure stable oil sources through check valve 8 for the steering boost system of automobile.
Certainly, above-mentioned explanation is not a limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also belong to protection scope of the present invention.
