Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and principle of work, manufacturing process and operation using method etc., be described in further detail, to help, those skilled in the art conceive utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
ABS hydraulic circuit principle of work shown in Fig. 1 comprises Four processes: conventional brake, decompression process, pressurization, voltage stabilizing process.
(1) conventional brake: when chaufeur depresses brake pedal 1, slip rate S<20%, now ABS does not work, and switch valve is opened.Now the flow direction of braking liquid is from brake pump 11---A chamber 9---and switch valve---B chamber 10---brake cylinder 12, the increase with brake pedal 1 power increases by the pressure of braking liquid;
(2) decompression process: when ECU detects slip rate S>20%, automobile (ABS) anti-skid brake system will get involved work.ECU will give the input and output solenoid valves of multifunctional electromagnetic valves 7, opens after input solenoid valves, closes after output solenoid valve energising.The C chamber that high pressure control liquid will pass through bottom voltage regulation cylinder 8, piston will be pushed and move, and A chamber 9 and B chamber 10 are separated, and so will be cut off from master brake cylinder to the braking liquid loop of brake wheel wheel cylinder.B chamber 10 volume is increased, and pressure reduces.
(3) pressurization: when ECU detects slip rate S<20%, ECU control inputs and output solenoid valve power-off, now input closed electromagnetic valve, and output solenoid valve is opened.Control fluid and flow into fluid reservoir 6, high-voltage oil liquid flows out from C chamber, voltage regulation cylinder 8 lower end, and piston declines, and B chamber 10 volume reduces, and pressure increases;
(4) voltage stabilizing process: when ECU detect slip rate S level off to 20% time, ECU control inputs and output solenoid valve energising.Wherein, close after input solenoid valves, also close after output solenoid valve energising.Now movable piston will produce displacement switch valve is closed.So, namely A chamber 9 and B chamber 10 are cut off, and B chamber 10 volume will be stablized constant.It is constant that pressure maintains initial value.
In whole braking procedure, ABS system is ceaselessly cycled to repeat conventional brake, decompression process, pressurization, voltage stabilizing process Four processes, makes the slip rate of automobile remain at about 20%, both ensure that safety, achieve again good braking effect.
Low pressure oil in fluid reservoir 6 is converted into high pressure oil by boost pump 4 in fig. 2 and energy recovery device of automobile exhaust 5 collaborative work, namely presses to energy storage by check valve 3, is the hydraulic energy of hydraulic oil 53 in this process by the thermal energy of motor exhaust.In braking procedure for brake cylinder 12 provide energy work as pressure reach designated value time, check valve 3 is opened, and is flowed in accumulator 2 store, for next process is prepared by hydraulic circuit.
In order to ensure ABS system worked well, the pressure needed for hydraulic oil 53 in accumulator 2 need reach 18MPa.In vehicle traveling process, energy recovery device of automobile exhaust 5 absorbs the heat in tail gas, and is passed to the kerosene 56 of sealing in elasticity leather bag 52, the volume of kerosene 56 is changed, finally makes the volume of elasticity leather bag 52 increase.Hydraulic oil 53 in rigidity pressure casing 51 is pressed in accumulator 2.Along with the increase of elasticity leather bag 52 volume, elasticity leather bag 52 finally can be full of outer rigid housing 51, and the hydraulic oil 53 now in accumulator 2 remains on 18Mpa.
Automobile just travelled soon or ambient temperature lower, the tail gas in freeing pipe 54 can not provide enough energy to be pressed in accumulator 2 from fluid reservoir 6 by hydraulic oil 53.In this case, when the pressure of hydraulic oil 53 is lower than 15 MPa, the ECU on multifunctional electromagnetic valves 7 can control boost pump 4 and start working, and presses in accumulator 2 by the hydraulic oil 53 in fluid reservoir 6 through check valve 3; When the pressure of the hydraulic oil 53 in accumulator 2 reaches 18MPa, switch disconnects, and boost pump 4 quits work, and under guaranteeing any operating mode, ABS can normally work.
In ABS Braking system process, i.e. the three phases of decompression, pressurize, supercharging, by energising and the power-off of multifunctional electromagnetic valves 7, opening and closedown of control plunger, has assisted the process of voltage regulation cylinder 8 voltage stabilizing, pressurize and supercharging.Under normality, under the effect of main spring tension force, by sliding plunger, switch valve is backed down, A chamber 9 is communicated with B chamber 10, to connect the braking liquid loop of master brake cylinder and brake wheel wheel cylinder.In abs braking process, by changing the volume size in each chamber in cylinder, reach the object of decompression, pressurize and supercharging.
Fig. 3 is energy recycle device principle assumption diagram, energy recovery device of automobile exhaust 5 outside is withstand voltage outer rigid housing 51, internal layer is elasticity leather bag 52, it is wrapped in around the exhaust pipe of engine 54 road wall, has high temperature high voltage resistant, good, the anticorrosive aging of contractibility, feature that adiathermancy is good.An airtight space is formed between elasticity leather bag 52 and the exhaust pipe of engine 54, be filled with kerosene 56, when high-temperature engine tail gas is discharged by freeing pipe 54, the kerosene 56 that its heat will be passed to rapidly by the overheater 55 be wrapped on freeing pipe 54 in elasticity leather bag 52, after kerosene 56 is heated, volume expands, and will form thermometer bulb.Being in High Temperature High Pressure air between elasticity leather bag 52 and the exhaust pipe of engine 54 will expanded by heating, and the pressure of the hydraulic oil 53 between pressure casing 51 and thermometer bulb is raised.That hydraulic oil 53 is pressed in accumulator 2 by check valve 3 by what fill in the space between elasticity leather bag 52 and rigidity pressure casing 51.Achieve heat energy to hydraulic pressure transformation of energy.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
