Description

Kinetic energy accumulation fuel-saving system for motor vehicles
The present invention is a kind of kinetic energy accumulation fuel-saving system that can be used for various power actuated vehicles, particularly automobile.
As everyone knows, various power actuated vehicles such as automobile are that the friction drag that utilizes brake equipment to produce is realized slowing down or stopping.Glancing impact, fuel consumption and heat energy dissipation that the vehicle energy that obtains becomes on the drg have fallen.According to the pertinent data introduction, the board automobile of making a leapleap forward that load-carrying is 2.5 tons, when the speed of a motor vehicle when 50 kilometers/hour drop to 30 kilometers/hour, the automobile kinetic energy that braking consumes needs change with the heat energy of 30~40 milliliters of gasoline; The Jiefang brand automobile that load-carrying is 4 tons, when the speed of a motor vehicle drops to when stopping from 40 kilometers/hour, the kinetic energy that braking consumes is equivalent to consume 100 milliliters in gasoline; The fuel oil that the driving engine normal starting is once required can be bought car in installments and be travelled 200~1000 meters.Then be multiplied in fault or the required fuel oil of starting cold season.Starting continually, reinforcing, braking and parking are the common features of all power actuated vehicles, and urban transit bus is more outstanding.This waste of power is considerable, and has increased environmental pollution.
Task of the present invention just provides a kind of way and device of the inertia kinetic energy can store motor vehicle brake the time, to reduce the invalid loss of fuel oil.
The kinetic energy accumulation fuel-saving system of the present invention's power actuated vehicle (particularly automobile), it is the invertibility of utilizing liquid pump-hydraulic motor, adopt hydraulic accumulator, inertia kinetic energy during with car brakeing converts fluid pressure to by the mechanical-hydraulic device and can store, can discharge hydraulic pressure when needing, assist vehicle launch or reinforcing by the hydraulic-machinery device.
Adopt the present invention's kinetic energy accumulation fuel-saving system for motor vehicles, because of kinetic energy can store, do not need to replace braking to come fuel-economizing to slide, so can improve the economy of Vehicle Speed and operation, performances such as vehicle launch, reinforcing, braking and vibration damping have been improved simultaneously, prolonged the life-span of brake system, in addition, because of fuel-economizing has also reduced the caused environmental pollution of exhaust emission simultaneously.
Explain content of the present invention below in conjunction with accompanying drawing.
Fig. 1 shows the working condition of system when car brakeing or parking.
Fig. 2 shows the working condition of system when vehicle launch or reinforcing.
The present invention's kinetic energy accumulation fuel-saving system for motor vehicles is to come design-calculated according to present generally driver's operating habit.Just can realize the glancing impact energy storage automatically and exoergic when afterburning without any need for additional move.
The braking stored-energy process as shown in Figure 1, when foot is gently stepped on brake pedal, before the braking gas circuit is not opened, earlier by pressurized air (or electric power or fluid power or machinery) effect, be (P, the E) among Fig. 1, power-transfer clutch (17) is engaged, and the inertia of automobile drags oil pump (1) rotation by the last power take-off gear (16) of change speed gear box (14), transmission gear (15), power-transfer clutch (17), and the oil in the fuel tank (2) is pressed into energy storage (6) by hydraulicchange-over valve (3), check valve (5).After pressure in the energy storage (6) is set up, open hydraulicchange-over valve (8), pressure oil to hydraulic clutch (17), keeps and increases the engaging force of power-transfer clutch by the oil circuit shown in the dotted line among the figure, and system is worked reliably.Rising along with hydraulic pressure in the energy storage.It stops the counter torque of oil pump rotation also to increase thereupon, and makes car brakeing.Inertia kinetic energy during car brakeing just converts fluid pressure to and can be stored in the energy storage like this.The pressure oil that surpasses accumulator volume discharges by safety valve (7), the top pressure of restriction hydraulic efficiency pressure system.Pressure in compression indicator (9) the indication energy storage.Car deceleration is after parking, and check valve (5) is sealed the hydraulic pressure energy in the accumulator up for safekeeping, and prevents that oil pump from reversing.Because power-transfer clutch this moment (17) keeps engaging under hydraulic coupling, this system also can strengthen hand braking effect.
When the anxious glancing impact of need, firmly step on brake pedal, in hydraulic efficiency pressure system energy storage braking, opened the brake equipment gas circuit, at this moment, hydraulic storage energy brake and mechanical friction braking are worked simultaneously, realize stronger braking.
Starting or the exergonic process when afterburning when the light accelerator pedal of foot, make change-over valve (4) commutation by machinery or electric power as shown in Figure 2.If have pressure oil in the energy storage this moment, then make hydraulicchange-over valve (3) commutation through change-over valve (8) and change-over valve (4), the pressure oil in the energy storage (6) drives oil pump (1) rotation by change-over valve (3), make oil pump become oil motor, (turning to identical) with crude oil pump.By under the pressure of energy storage, keeping oncoming clutch (17), gear (15), gear (16) to drive the transmission shaft of change speed gear box (14), assist or replacement actuating motor starting vehicle motor, or give whole vehicle reinforcing.The efficient of this system depends primarily on the work efficiency of liquid pump-hydraulic motor.
Release along with energy, when the pressure in the energy storage drops to certain value, change-over valve (8) resets under action of the spring, the cut-off pressure oil circuit, under action of the spring, power-transfer clutch (17) is thrown off, and change-over valve (3) resets, system is preparation and accepts the braking stored-energy state once more, and throws off with the machine driven system of vehicle.Vehicle continues to travel under general state.So not only can reduce the waste of power of oil pump idle running, and can prolong the service life of system.Change-over valve (8) is equivalent to a sequence valve, just opens during to certain pressure, to guarantee the positive engagement of power-transfer clutch, then closes when being lower than certain pressure, keeps in the energy storage certain excess pressure being arranged.
During vehicle ', owing to Uneven road causes the up-down vibration on spring top, its loss the kinetic energy that advances of vehicle.To this inevitable vibration, a lot of vehicles are often decayed it by the shock damping action of liquid damper, and this part vibrational energy is lost by the heat energy that throttling pore converts liquid to repeatedly.For reclaiming this part energy, the additional device that claim 2 is proposed is as shown in the long and short dash line frame among Fig. 2, driving damping energy storage piston (13) during vehicle damping spring (10) vibration pumps, open one group of check valve (11) or another group check valve (12) respectively, oil in the fuel tank (2) is sucked oil cylinder, and be pressed into hydraulic accumulator (6), when shock damping action is taken place in vibration, become the partial vibration transformation of energy hydraulic pressure to store, in order to assisting the usefulness of vehicle reinforcing.
Hydraulic valve in this system can make up by the selection standard hydraulic part, also can be designed to special multifunction integrated valve series, to adapt to the needs of various vehicles, especially will show its economy when mass production.
This economizer system is simple, not only can be used for designing the motor vehicles such as new automobile, and can be used for the motor vehicles such as existing automobile are carried out add-assembly.
