Abstract
The utility model relates to an environmental protection energy saving device for an urban bus, which can proceed on the basis of reserving the original bus model structure. A hydraulic control part and a bus transmission system are connected by use of the engagement of gears, and further, the hydraulic control part is connected with an oil motor of an oil pump via a clutch on a transmission shaft of the oil motor of the oil pump. When the bus transmission system is engaged with the gears and drives the oil motor of the oil pump to rotate via the clutch, the oil motor of the oil pump sends pressure oil to an energy accumulator for storing energy. Contrarily, the pressure oil of the energy accumulator is output to drive the oil motor of the oil pump, and a dynamic force is sent to a bus gearbox via the clutch and the engagement of the gears.
Description
The utility model relates to a kind of urban public traffic vehicles environment protecting power economizer, belong to traffic and transport field.
The characteristics of urban public traffic vehicles operation are many for stopping, braking is frequent, cause the high and increase urban air pollution of power consumption, the professional tries hard to make right material performance maximal efficiency for this reason, some improvement in the design of mechanism, have been done, but still there are some problems, as: too complicated, the former vehicle change of mechanism is excessive, cost is expensive, makes the application scenario be subjected to great restriction.
The purpose of this utility model mainly is to overcome deficiency of the prior art, proposed a kind of energy saver and newly designed, when having realized reclaiming the urban public traffic vehicles operation because of braking the energy that is frequently consumed.
The technical solution of the utility model is mainly under the situation that does not change former vehicle structure, the principle of transformation of energy is used for the utility model, first, increase and designed a cover hydraulic efficiency gear, the energy of being wasted when being mainly used in car brakeing promptly is converted into oily pressure energy to the kinetic energy of vehicle movement by hydraulic efficiency gear, and pressure can be able to store, can be converted into the kinetic energy output that gear rotates to the pressure of oil by hydraulic efficiency gear in the time of also can or quickening, start vehicle at vehicle start; Second increases and to have designed circuit kit, signal such as be used to send the work of modulated pressure device, stop.
The utility model is braked stop more can be energy-conservation significantly in the frequent running environment, promptly the power that braking, the kinetic energy that slows down have been stored when being used as startup for the second time, acceleration utilizes again, especially combine China's national situation, under the situation that keeps former vehicle structure, set up hydraulic efficiency gear and circuit, structure is simple more than prior art, and can also reduce aerial contamination to the city bus automobile, the utlity model has very strong practical value and application prospect.
Below with reference to accompanying drawing feature of the present utility model is described in detail:
Fig. 1 the utility model hydraulic efficiency gear scheme drawing
Fig. 2 the utility model circuit diagram
As shown in Figure 1 and Figure 2, the utility model mainly comprises hydraulic efficiency gear control part and circuit control part, and the hydraulic efficiency gear control part mainly comprises: energy storage 1, compression indicator 2, hydraulic control one-way valve 3, two-position four-way solenoid directional control valve 4, by pass valve 5, oil filter 6, oil pump-oil motor 7, check valve 8, fuel tank 9, Hydraulic Pump transmission shaft hydraulic clutch 10, Hydraulic Pump shaft gear 11, sequence valve 12, reducing valve 13, power-assisted oil cylinder 14, two-position three way solenoid directional control valve 15; Electric control system mainly comprises: source switch K, five grades of gear micro-switchs, comprise open contact WK5-1 and normally closed contact WK5-2, fourth gear gear micro-switch, comprise open contact WK4-1 and normally closed contact WK4-2, third gear gear micro-switch, comprise open contact WK3-1 and normally closed contact WK3-2, second gear gear micro-switch comprises open contact WK2-1 and normally closed contact WK2-2, the brake pedal micro-switch comprises open contact WKB1, WB2, and the electromagnetic control part DT2 of two-position three way solenoid directional control valve 15 electromagnetic control part DT1 and two-position four-way solenoid directional control valve 4.The utility model can carry out on the basis that keeps former vehicle type structure, by utilizing gear 11 and gear 16 engagements that the driving system of fluid control part with vehicle coupled together, gear 11 can link to each other with 7 of oil pump-oil motors by the power-transfer clutch 10 on oil pump-oil motor 7 transmission shafts again, when gear 16 driven wheels 11, can drive oil pump-oil motor 7 by power-transfer clutch 10 rotates, oil pump-oil motor 7 is transported to energy storage 1 to pressure oil with energy storage, otherwise, the pressure oil output of energy storage 1 is driven oil pump-oil motor 7, power is sent into the change speed gear box of vehicle by the engagement of power-transfer clutch 10 and gear 11 and gear 16.
When vehicle need reclaim kinetic energy, the people makes two-position three way solenoid directional control valve 15 electromagnetic control part DT1 energising for providing signal, pressure oil in the energy storage 1 enters reducing valve 13 through two-position three way solenoid directional control valve 15, promoting power-assisted oil cylinder 14 then separates vehicle power source with running part, then power-transfer clutch 10 is engaged by sequence valve 12, at this moment the kinetic energy of vehicle is through gear 16, gear 11, oil pump-oil motor 7 is rotated, oil pump-oil motor 7 from fuel tank 9 through check valve 8 oil suctions, pressure oil is through oil filter 6, two-position four-way solenoid directional control valve 4, hydraulic control one-way valve 3 enters energy storage 1, after vehicle stops, disconnect the electric current of two-position three way solenoid directional control valve 15 electromagnetic control part, when oil pressure surpasses the pressure that allows, by pass valve 5 automatically unloadings.
When vehicle launch, the people is for providing signal, make two-position three way solenoid directional control valve 15 and two-position four-way solenoid directional control valve 4 electromagnetic control part DT1 and DT2 energising, under the control of two-position three way solenoid directional control valve 15, power-assisted oil cylinder 14 separates vehicle power source 5 running parts, at this moment power-transfer clutch 10 partly combines oil pump-oil motor 7 and system of vehicle transmission, hydraulic control one-way valve 3 is opened simultaneously, pressure oil in the energy storage 1 enters oil pump-oil motor 7 through the two-position four-way solenoid directional control valve, make its rotation, output kinetic energy, vehicle is quickened, disconnect two-position three way solenoid directional control valve 15 and the DT1 of electromagnetic control portion of two-position four-way solenoid directional control valve and the electric current of DT2 behind certain speed, the vehicle of motion drives vehicle motor and starts.
Micro-switch is installed on by the declutch shift shaft of transmission for vehicles loam cake, if a certain gear quits work, then corresponding gear micro-switch contact keeps often opening with normally closed; As a certain gear engaged, then corresponding gear micro-switch contact changes state, the open contact closure, and normally closed contact is opened.Brake pedal micro-switch normally closed contact WB1, WB2 be when depressing the play motion of brake pedal, but glancing impact not also, WB1, WB2 are converted to closure state by normally open.As shown in Figure 2,, and depress the play motion of brake pedal when five grades or fourth gear work, but glancing impact not as yet also, the DT1 of two-position three way solenoid directional control valve 15 just switches on, and this device just is in the recover kinetic energy state; When third gear or second gear work, and depress the play motion of brake pedal, but glancing impact not as yet also, the DT2 of the DT1 of two-position three way solenoid directional control valve 15 and two-position four-way solenoid directional control valve 4 just switches on, and this device just is in the energy dispose procedure of pressure oil.
